Esri EGMP2201 Dumps

Scenario Overview:

Editors are spending multiple hours resolving conflicts during reconciliation.

Key points:

Conflicts are detected by attribute (not by object).

Traditional versioning is used.

Weekly compression and weekly reconcile/post workflows are in place.

Why Reconcile and Post Daily?

Conflicts occur when multiple editors make overlapping edits. The longer versions remain unreconciled, the more conflicts accumulate, leading to time-consuming resolution.

Daily reconciliation and posting minimizes the number of changes between the parent and child versions, reducing the likelihood and volume of conflicts.

(ArcGIS Documentation: Reconcile and Post)

Key Benefits of Daily Reconciliation:

Fewer Changes to Compare: With fewer edits accumulated in each version, conflict detection is faster.

Less Complex Conflicts: Simplifies resolution since changes are smaller and more recent.

Improved Editor Productivity: Editors spend less time resolving conflicts, freeing up time for other tasks.

Alternative Options:

Option A: Detect conflicts by object

While this may reduce conflict granularity, it can lead to overwriting valid edits at the object level, which may not be acceptable in collaborative workflows.

Option B: Compress the geodatabase daily

Compression reduces the state tree and improves performance but does not directly reduce the number of conflicts during reconciliation.

Therefore, implementing daily reconciliation and posting is the most effective way to reduce conflicts and improve editing efficiency.

Scenario Overview:

The analyst creates a join between a large dataset and a nonspatial table to calculate an attribute field.

An error occurs, indicating that the join field is not indexed.

Cause of the Problem:

Joins between datasets rely on indexed fields to optimize the join operation. Without an index, the system must perform a full table scan, which can lead to errors or slow performance when working with large datasets.

Solution:

Running theAdd Attribute Indextool creates an index on the join field, enabling efficient joining operations.(ArcGIS Documentation: Attribute Indexes)

Steps to Resolve:

Open theAdd Attribute Indextool in ArcGIS Pro.

Select the nonspatial table as the input dataset.

Choose the field used in the join operation as the field to index.

Run the tool to create the attribute index.

Alternative Options:

Option A:Add Spatial Index is irrelevant for nonspatial data.

Option C:Rebuild Indexes reorganizes existing indexes but cannot create new ones, which is required here.

Thus, the analyst should run theAdd Attribute Indextool to resolve the error.

 Understanding the Scenario:The GIS administrator lacks database administrator credentials but requires an enterprise geodatabase for vector data storage. In this setup, the database administrator (DBA) is responsible for preparing the database, including setting up users and permissions, while the GIS administrator is tasked with enabling it as an enterprise geodatabase.

 Tool Selection Overview:

Create Feature Dataset:This tool is for creating a logical grouping of related feature classes inside an existing geodatabase. It is unrelated to enabling or creating an enterprise geodatabase.

Enable Enterprise Geodatabase:This tool is used when a database has already been created and configured by the DBA, and the GIS administrator needs to enable it as an enterprise geodatabase. It adds geodatabase system tables and functionality to the database. This aligns with the scenario described.

Create Enterprise Geodatabase:This tool creates a new database and configures it as an enterprise geodatabase in one step.However, this tool requires database administrator credentials, which the GIS administrator in this scenario does not have.

 Key Steps to Enable an Enterprise Geodatabase:

Preparation by DBA:The DBA sets up the database, ensuring the appropriate users and permissions are in place. They also provide connection details to the GIS administrator.

Using the Enable Enterprise Geodatabase Tool:

Navigate toArcGIS ProorArcGIS Enterprise tools.

Open theEnable Enterprise Geodatabasetool.

Specify the database connection file for the target database.

Provide the authorization file (a valid ArcGIS Server Enterprise license file) to enable geodatabase functionality.

Execute the tool to add system tables, stored procedures, and geodatabase functionality to the database.

 References:

ArcGIS Pro Documentationon Enable Enterprise Geodatabase.

Esri Enterprise Geodatabase Concepts: Official Esri documentation provides comprehensive details on the role of DBAs and GIS administrators in setting up enterprise geodatabases.

ArcGIS Enterprise Licensing Guide: Detailed information about authorization files for enabling geodatabases.

 Why the Correct Answer is B:The tool “Enable Enterprise Geodatabase” is specifically designed for situations where the database setup is handled by a DBA, and the GIS administrator is responsible only for enabling geodatabase capabilities. Since the GIS administrator does not have DBA credentials, they cannot use the “Create Enterprise Geodatabase” tool, which would require those credentials to create and configure a new database.

Scenario Overview:

An editor updates500,000 recordsin achild versionof the Default version using a field calculation.

Another editor updates the Default version, and thechild version is reconciledwith Default.

What Happens During Reconciliation?

In traditional versioning, edits to feature classes are stored in theAddsandDeletes tables.

During reconciliation:

Changes in the child version that differ from the Default version areduplicatedin the Adds and Deletes tables to track the differences.

This allows conflicts to be detected and resolved while preserving all edits.(ArcGIS Documentation: Traditional Versioning Workflow)

Alternative Options:

Option B: They will be migrated to the Base table

Migration to the base table occurs only when changes are posted and the geodatabase is compressed.

Option C: They will be removed from the States repository table

The States repository table tracks state transitions and is unaffected during reconciliation.

Thus, during reconciliation, the500,000 records are duplicated in the Adds and Deletes tablesto manage and detect conflicts.

To migrate an enterprise geodatabase to another server while changing its name and repository table owner, creating anew enterprise geodatabaseis the most appropriate workflow.

1. Why Create a New Enterprise Geodatabase?

New Geodatabase Name: Creating a new geodatabase allows specifying a different name for the database.

Change Repository Table Ownership: During the setup of the new geodatabase, the repository tables can be assigned to a new owner (e.g., DBO instead of SDE).

Fresh Configuration: This method provides full control over database settings, structure, and ownership during migration.

2. Why Not Other Options?

Restore a Database Backup:

Restoring a backup would preserve the original database name and ownership settings, which conflicts with the requirement to change these configurations.

Migrate Storage Geoprocessing Tool:

This tool is used for changing the storage type of geodatabase tables (e.g., from binary to XML). It is not designed for migration or renaming geodatabases or altering repository table ownership.

3. Steps to Create a New Enterprise Geodatabase:

Create the New Geodatabase:

Use theCreate Enterprise Geodatabasegeoprocessing tool in ArcGIS Pro or database-specific tools to set up the new geodatabase on the target server.

Configure the repository tables to use the desired owner (e.g., DBO).

Export Data from the Old Geodatabase:

UseGeodatabase replication,Export to File Geodatabase, or other export tools to migrate data to the new geodatabase.

Import Data to the New Geodatabase:

Load the exported data into the new geodatabase using theImport/Load Datatools.

Update Services and Connections:

Update database connection files and any published services to point to the new geodatabase.

References from Esri Documentation and Learning Resources:

Creating an Enterprise Geodatabase

Migrating Enterprise Geodatabases

Conclusion:

Creating anew enterprise geodatabaseis the best method to meet the requirements of renaming the database and changing the repository table owner.

To create database connection files that point to a specific edit version for users, theGeodatabase Connection Propertiesoption should be used.

1. What are Geodatabase Connection Properties?

This option allows you to set specific connection details, such as the target version (edit version) within a traditionally versioned geodatabase.

It ensures that each user connects directly to their designated version, isolating edits and preventing conflicts in multi-user environments.

2. Why Use Geodatabase Connection Properties?

Provides control over which version of the geodatabase the user accesses.

Ensures security and consistency by directing users to their designated edit versions rather than the default version.

Allows administrators to pre-configure connection files for distribution to users.

3. Why Not Other Options?

Connection Properties:

Refers to general connection details like username, password, and server but does not allow specifying a particular version.

Database Properties:

Refers to database-level settings but does not configure specific user-level connection details, such as the target version.

Steps to Use Geodatabase Connection Properties:

InArcGIS Pro, go to theCatalog Pane.

Create a new database connection by selectingAdd Database.

In the connection properties dialog, specify:

The user’s credentials.

Thespecific versionthe user will edit under the Geodatabase Connection Properties section.

Save the connection file and distribute it to the user.

References from Esri Documentation and Learning Resources:

Database Connections in ArcGIS Pro

Versioned Database Connections

Conclusion:

UsingGeodatabase Connection Propertiesensures that each database connection file is pre-configured to point to the appropriate edit version for the user, enhancing security and workflow efficiency.

 Understanding the Scenario:

The feature class is versioned and participates in a geodatabase topology.

The goal is to reload data while maintaining versioning and topology integrity.

 Key Considerations for Reloading Data:

Truncate Table:TheTruncate Tabletool efficiently deletes all rows in the feature class without logging individual row deletions in the geodatabase. It is the preferred method for clearing data while minimizing impact on performance.

Append Tool:After truncating the table, theAppendtool can load new data into the feature class, ensuring that the topology and versioning structure remain intact.

Avoiding Delete Rows:Deleting rows manually logs each deletion in delta tables, leading to a potential performance bottleneck and unnecessary transaction logging, especially for versioned datasets.

Geodatabase Topology Consideration:Topology rules will need to be validated after reloading the data to ensure spatial integrity.

 Steps to Reload Data:

Use theTruncate Tabletool to remove existing records.

Use theAppendtool to load the new data into the feature class.

Validate the topology in the geodatabase to check for any errors after the reload.

 References:

Esri Documentation: Truncate Table.

Loading Data into Versioned Feature Classes: Best practices for versioned and topology-aware datasets.

 Why the Correct Answer is A:Running theTruncate Tabletool ensures efficient data clearing, and using theAppendtool maintains the geodatabase's versioning and topology structure. Options B and C involve unnecessary row-level deletions, which are inefficient and could disrupt the versioned workflow.

To track feature class changes while keeping thereconcile, post, and compress processesseparate from thereplica synchronization process, the best approach is tocreate a one-way replica using the archive option on Default.

1. Why Use a One-Way Replica on Default?

One-Way Replication:

Sends data changes from the parent (Default version) to the child geodatabase, ensuring that synchronization does not interfere with the parent geodatabase’s versioning operations.

Archive Option:

Archiving captures all changes to the feature class, providing a history of edits without requiring versioning in the replica.

2. Why Choose the Default Version?

Using the Default version as the parent ensures that all reconciled and posted changes are synchronized to the replica, making the synchronization independent of ongoing versioning workflows in the geodatabase.

3. Why Not Other Options?

Create a One-Way Replica Using the Archive Option on a Child Version of Default:

Replicating from a child version complicates workflows because the child version must be reconciled and posted to Default before updates are reflected in the replica.

Create a Two-Way Replica Using the Archive Option on Default:

Two-way replication synchronizes changes in both directions. This would integrate changes from the child geodatabase into Default, interfering with the reconciliation and posting processes.

Steps to Create the Replica:

Ensure archiving is enabled for the feature classes in the Default version.

Use theCreate Replicatool in ArcGIS Pro and selectOne-Way Replication.

Configure the replica to include the archive option.

Synchronize the replica as needed without affecting versioning processes in the parent geodatabase.

References from Esri Documentation and Learning Resources:

One-Way Replication Overview

Geodatabase Archiving

Conclusion:

To track changes while separating reconcile, post, and compress processes from synchronization, the GIS analyst shouldcreate a one-way replica using the archive option on Default.

To identify which user was responsible for creating each feature in a global enterprise geodatabase, enablingeditor trackingis the appropriate strategy.

1. What is Editor Tracking?

Editor tracking records metadata about feature creation and updates, including:

Whocreated or updated a feature.

Whenthe feature was created or updated.

This information is stored in four additional fields:

Creator

Creation Date

Editor

Edit Date

2. Advantages of Editor Tracking

Automatically tracks and populates user and timestamp fields for feature edits.

Requires no manual intervention by users, ensuring accuracy and consistency.

Works seamlessly in multi-user environments, including enterprise geodatabases.

3. Why Not Other Options?

Add a Global ID:

Global IDs are used to uniquely identify features but do not track user edits or changes.

Use Relationship Classes:

Relationship classes establish connections between features or tables. They are not designed to record user actions or metadata.

Steps to Enable Editor Tracking:

OpenArcGIS Proand connect to the enterprise geodatabase.

Right-click the feature class or dataset and selectManage > Enable Editor Tracking.

Specify the fields for storing creator, editor, creation date, and edit date.

Save and apply the changes.

References from Esri Documentation and Learning Resources:

Editor Tracking—ArcGIS Pro Documentation

Tracking Edits in Enterprise Geodatabases

Conclusion:

Enabling editor trackingis the most effective strategy to identify which user created each feature in a global enterprise geodatabase.

Scenario Overview:

The wells feature class has one row per well.

The well_inspections table has one row for each inspection of a well.

Inspection dates from the well_inspections table need to be displayed as labels clustered around each well on the map.

The goal is to establish a connection between these two datasets without permanently joining them, as the data is being displayed dynamically (inspection dates are clustered around the wells).

Relates in Geodatabases:

A relate is a type of table association in which tables are linked by a common key field but remain separate.

Relates allow for dynamic queries to retrieve related records without duplicating or permanently associating the data.

Using a relate, you can query all inspection dates for a specific well dynamically, display them on the map as labels, and preserve the integrity of both the wells and inspections datasets.

(ArcGIS Documentation: Relates)

Alternative Options:

Option A: Join

A join merges two tables into one virtual table, based on a shared key. However, this approach is static and inappropriate for displaying dynamically clustered labels since the tables would need to be rejoined after every update.

Option C: Relationship Class

A relationship class is a more permanent association that enforces rules between two datasets. It is ideal for maintaining relationships between data but is unnecessary for dynamically labeling inspection dates on the map.

Thus, a relate is the most efficient and appropriate option for this scenario.

 Understanding the Scenario:

Edits made to a feature class need to be immediately visible to all users.

This indicates a requirement for direct edits to the base tables without any versioning overhead.

 Editing Configuration Overview:

Traditional Versioned Editing:Edits are made to delta tables and require version reconciliation and posting to be visible to other users. This introduces a delay and does not meet the requirement for immediate visibility.

Nonversioned Editing:Edits are applied directly to the base table of the feature class, ensuring they are immediately visible to all users. This is the correct choice for the scenario.

Branch Versioned Editing:Edits are made in a branch version and are not immediately visible to other users unless the edits are saved to the default branch. This is not the best choice for immediate visibility.

 Steps to Configure Nonversioned Editing:

Ensure the feature class is set to nonversioned editing mode in the enterprise geodatabase.

Grant necessary permissions for all users to edit the base table.

All edits made to the dataset will instantly reflect for all users.

 References:

Esri Documentation: Nonversioned Editing.

 Why the Correct Answer is B:Nonversioned editing is the only configuration that ensures immediate visibility of edits to all users. Traditional and branch versioning involve workflows that delay edit visibility.

Scenario Overview:

Editors reconcile and post daily, but read-only versions created for analysis are not reconciled or posted.

The geodatabase is compressed nightly, but performance continues to degrade.

Cause of the Problem:

Unreconciled versions, including read-only ones, persist in the state tree, preventing the geodatabase compression from fully collapsing unused states.

Over time, this results in a bloated state tree and worsened performance.

Solution:

Reconciling and posting the read-only versions ensures that the state tree is cleared of unnecessary versions, enabling compression to collapse the database to its optimal state.

(ArcGIS Documentation: Reconcile and Post)

Alternative Options:

Option B: Creating a database view provides a read-only representation of data but does not address the underlying issue of unresolved states in the state tree.

Option C: Disabling editor tracking is unrelated to state tree performance issues and has no impact on the reconciliation or compression processes.

Therefore, reconciling the read-only versions will significantly improve performance.

For a large government organization requiring an equivalent data presence in a standby data center,database replicationis the ideal solution.

1. What is Database Replication?

Database replication involves duplicating data from a primary database to a secondary database in near real-time or on a scheduled basis.

This ensures that both databases are synchronized and capable of serving data if one fails.

2. Why Database Replication Fits the Requirement

Standby Data Center: Database replication provides a fully equivalent copy of the data in the secondary data center.

High Availability and Disaster Recovery: If the primary database is unavailable, the standby database can immediately take over, ensuring business continuity.

3. Why Not Other Options?

Geodatabase Replication:

While it is designed for replicating geodatabase content, it is typically used for GIS-specific workflows, such as syncing field edits. It does not ensure equivalence for non-spatial components of the database.

It is not ideal for large-scale, organization-wide replication needs.

Disconnected Synchronization:

This is used in offline editing workflows where devices sync their edits with a central database at a later time. It is not suitable for maintaining an equivalent standby database.

4. Types of Database Replication

Asynchronous Replication: Updates are replicated at scheduled intervals, offering flexibility but with slight delays.

Synchronous Replication: Updates occur in real-time, ensuring both databases are always identical.

Steps to Implement Database Replication:

Configure the primary and standby databases in the organization’s DBMS (e.g., SQL Server, PostgreSQL, Oracle).

Use the DBMS's built-in replication tools (e.g., SQL Server's Always On, PostgreSQL’s Streaming Replication).

Set up monitoring to ensure the replication process is functioning correctly.

References from Esri Documentation and Learning Resources:

Database Replication in DBMS

Disaster Recovery with Database Replication

Conclusion:

Database replicationis the recommended technology to establish an equivalent data presence in a standby data center, ensuring high availability and disaster recovery.

Scenario Overview:

The user requires a standard database view of theroads feature classthat resides in a different geodatabase from the primary enterprise geodatabase.

Theroads feature classis frequently edited, and the user needs the view to recognize updates immediately.

Replica Types in ArcGIS:

One-way replicationwith thefull modelis suitable for scenarios where the parent geodatabase sends updates to the child geodatabase, and all schema and data changes are synchronized.

In thefull model, the child database retains versioning and acknowledges updates as they occur in the parent database, enabling the user to see immediate updates in their standard view.(ArcGIS Documentation: Geodatabase Replication Types)

Key Features of the Full Model:

Synchronizesboth schema and datachanges.

Suitable for feature classes withfrequent edits.

Ensures that the standard database view reflects updates immediately upon synchronization.

Alternative Options:

Option A:The simple model in one-way replication supports data-only synchronization and does not update schema changes, making it insufficient for dynamic environments.

Option C:Two-way replication is unnecessary since the edits occur only in the parent geodatabase.

Thus,one-way replication with the full modelis the appropriate choice to meet the requirement.

Scenario Overview:

The GIS data administrator needs to prepare data for offline workflows.

Offline workflows allow users to take data offline for use in disconnected environments, typically for field operations.

Why Enable Sync?

Sync must be enabled on the feature service to allow offline workflows. This capability ensures that edits made offline can later be synchronized with the enterprise geodatabase.

When sync is enabled, data can be downloaded for offline use in supported applications like ArcGIS Field Maps, and changes can be synchronized back to the geodatabase.

(ArcGIS Documentation: Sync)

Alternative Options:

Option A: Enable Archiving

Archiving tracks historical edits but is not required for offline workflows.

Option B: Add Global IDs

While Global IDs are required for enabling sync, adding them alone does not fully configure the dataset for offline workflows.

Thus, to prepare data for offline workflows, the administrator must enable sync on the dataset.

 Understanding the Scenario:The GIS administrator wants to simultaneously grant access to multiple users for a branch-versioned feature class in an enterprise geodatabase. Managing permissions for individual users can be inefficient, especially for larger teams, making roles a better solution.

 Why Grant Permissions to a Role:

Role-Based Access Control (RBAC):In enterprise geodatabases, assigning permissions to a role allows administrators to define access levels once and apply them to multiple users who are members of that role. This simplifies management and ensures consistent permission levels across users.

Branch Versioning Considerations:In branch versioned datasets, role-based permissions ensure that all users working with the feature class can access, edit, or view data as needed without individual customization.

 Steps to Assign Permissions to a Role:

Create a role in the database or use an existing one.

Assign permissions for the branch versioned feature class to the role (e.g., read, edit, or administrative permissions).

Add users to the role.

All users in the role inherit the permissions automatically.

 References:

Esri Documentation: Best practices for managing permissions in enterprise geodatabases: Managing Users and Roles.

Branch Versioning Overview: Information on the unique requirements for branch versioned data: Branch Versioning.

 Why the Correct Answer is A:Using roles allows the GIS administrator to efficiently grant and manage access for multiple users at once. Options like lists or groups are not applicable in the context of enterprise geodatabases, as roles are the standard mechanism for assigning permissions.

Scenario Overview:

The organization has a web service thatmust always be available.

The service reads data from afeature classin an enterprise geodatabase.

The GIS administrator needs to update theschemaof the feature class.

Why Disable Schema Locking?

By default, ArcGIS services enforceschema lockingto ensure data consistency while the service is active. This prevents any modifications to the feature class schema (e.g., adding fields, altering attributes) while the service is running.

Disabling schema locking allows schema updates to occur without disrupting the service's availability.(ArcGIS Documentation: Schema Locking)

Steps to Disable Schema Locking:

Access the ArcGIS Server Manager.

Locate the web service and open itsservice properties.

In the advanced settings, disable theschema lockingoption.

Perform the required schema updates (e.g., adding fields or modifying the feature class).

Re-enable schema locking if necessary for normal operation.

Alternative Options:

Option B: Run the Alter Field geoprocessing tool

This tool modifies fields but cannot execute schema changes while schema locks are active.

Option C: Delete the spatial index

Deleting the spatial index is unrelated to schema changes and could degrade query performance.

Thus, the correct workflow is todisable schema locking on the serviceto allow schema changes without disrupting the web service.

 Understanding the Scenario:

ArcGIS Pro users needUndo/Redo functionality, which is available in versioned workflows.

SQL users also need to edit the dataset, requiring direct access to the database tables.

These requirements point to a need for a versioning method that supports both ArcGIS client workflows and SQL-based edits.

 Versioning Methods Overview:

Nonversioned Editing:Nonversioned editing allows direct editing of the database but does not support Undo/Redo functionality in ArcGIS Pro, making it unsuitable for this scenario.

Traditional Versioning:

Supports Undo/Redo functionality for ArcGIS Pro users.

Stores edits in delta tables (adds and deletes) to manage versions.

SQL users can access and edit the base tables, making it compatible with their needs.

Branch Versioning:Branch versioning supports modern workflows and web services but requires a service-based approach for editing. It does not allow direct SQL edits, making it unsuitable for this scenario.

 Steps to Implement Traditional Versioning:

Enable traditional versioning on the dataset in the enterprise geodatabase.

Ensure appropriate permissions are set for SQL users to access and edit the base tables.

ArcGIS Pro users will work in the versioned environment, allowing Undo/Redo operations during their edits.

 References:

Esri Documentation: Understanding Versioning.

Traditional Versioning Concepts: Best practices for using traditional versioning with multiple user types.

 Why the Correct Answer is B:Traditional versioning fulfills both requirements: Undo/Redo functionality for ArcGIS Pro users and SQL accessibility for direct edits.

To allow editors to see changes made to the default version in their child versions without reconciling, the dataset must be registered astraditional versioned with the option to move edits to base.

1. How This Versioning Method Works

When registering data astraditional versioned with the option to move edits to base, changes made in the default version are immediately visible to all child versions without requiring reconciliation.

This method directly updates the base table for default version edits, bypassing the delta tables used in standard traditional versioning workflows.

2. Why Use This Method?

Immediate Visibility: Editors can see default version updates in their child versions without the need for reconciliation or posting.

Simplified Workflow: Reduces the overhead of managing version reconciliation and posting for users who only need to view updates.

3. Why Not Other Options?

Branch Versioned with Global IDs and Editor Tracking Enabled:

Branch versioning is designed for feature services and web-based editing workflows. It does not allow direct visibility of default version changes in child versions.

Traditional Versioned with Archiving and Editor Tracking Enabled:

This method tracks historical changes but does not allow child versions to see updates in the default version without reconciliation.

Steps to Register Data with Move Edits to Base Option:

InArcGIS Pro, right-click the dataset or feature class and selectManage > Register as Versioned.

Check the option"Move edits to base"during registration.

Save the changes and verify that editors can view default version changes without reconciliation.

References from Esri Documentation and Learning Resources:

Traditional Versioning with Move Edits to Base

Versioning Options in Enterprise Geodatabases

Conclusion:

Registering the dataset astraditional versioned with the option to move edits to baseensures that editors can see changes made to the default version in their child versions without requiring reconciliation.
