 The difference between crash consistent and application consistent cloning methods is that the application consistent method ensures that the cloned virtual machine is in a consistent state with respect to the application and database, while the crash consistent method does not guarantee that1. The application consistent method uses the VMware snapshot or the Microsoft Volume Shadow Copy Service (VSS) to quiesce the application and flush the pending I/O operations to the disk before creating the clone, which prevents data corruption or loss2. The crash consistent method does not quiesce the application or flush the pending I/O operations, and creates the clone as if the virtual machine had crashed, which may result in data inconsistency or recovery issues3. The application consistent method is recommended for virtual machines that run database applications, such as SQL Server or Oracle, while the crash consistent method is suitable for virtual machines that run non-database applications, such as web servers or file servers4. The application consistent method is not available only for Linux operating systems (option D), as it also supports Windows Server operating systems that have VMware Tools or VSS installed5. The crash consistent method should not be used only for the virtual machines with Fault Tolerance enabled (option C), as it can be used for any virtual machine that does not require application consistency. Both methods are not the same,and the speed of cloning is not the only difference (option B), as they have different implications for the data integrity and availability of the cloned virtual machine. References:

According to the HPE SimpliVity Administration Guide1, the file level restore option allows you to recover individual files or folders from a backup of a virtual machine. Thisoption is useful when you need to restore a specific file that was accidentally deleted or corrupted, without affecting the rest of the virtual machine. The file level restore option supports both Windows and Linux based virtual machines, and can be performed using the HPE SimpliVity plugin in the vSphere Web Client. The file level restore option creates a temporary virtual machine from the backup, mounts the virtual disks, and copies the selected files or folders to a destination of your choice. The temporary virtual machine is then deleted automatically.

The other options are not suitable for recovering a single file from a Linux based virtual machine. Restoring a virtual machine from the backup would overwrite the entire virtual machine with the backup data, which may not be desirable or necessary. Moving a virtual machine from DR site to the primary site would not help if the file was deleted from both sites. Reverting to the SimpliVity snapshot would also overwrite the entire virtual machine with the snapshot data, which may not be the latest or the most relevant version. References:

 According to the HPE InfoSight for HPE SimpliVity Getting Started document1, HPE InfoSight provides the following functionality for HPE SimpliVity:

• Monitoring of cluster, node, and virtual machine performance, capacity, and health
• Reporting of system configuration, inventory, and compliance
• Analysis of trends, anomalies, and root causes
• Prediction of future resource needs and potential issues
• Recommendation of best practices and optimization actions

One of the key features of HPE InfoSight is the ability to monitor the latency of virtual machines, which is the time it takes for a request to be processed by the system. Latency is an important indicator of the performance and efficiency of the system, and HPE InfoSight provides detailed and granular data on the latency of each virtual machine, as well as the breakdown of the latency components, such as CPU, memory, network, and storage. HPE InfoSight also provides alerts and notifications when the latency exceedsthe predefined thresholds, and helps to identify and resolve the root causes of the latency issues.

Therefore, the correct answer is D. monitoring of virtual machine latency, as this is one of the functionality that HPE InfoSight provides for HPE SimpliVity. References:

 According to the HPE SimpliVity documents and learning resources, the difference between crash consistent and application consistent cloning methods is that the application consistent method ensures that the cloned virtual machine is in a consistent state with respect to the application data and transactions. This means that the application consistent method allows the pending 10 operations to finish before committing them to the database, and flushes the memory buffers and caches to the disk. This ensures that the cloned virtual machine can resume the application without any data loss or corruption. The crash consistent method, on the other hand, does not guarantee that the cloned virtual machine is in a consistent state with respect tothe application data and transactions. This means that the crash consistent method does not wait for the pending 10 operations to finish or flush the memory buffers and caches to the disk. This may result in some data loss or corruption if the cloned virtual machine resumes the application. The crash consistent method is faster than the application consistent method, but less reliable. The other options are incorrect because they are either false or irrelevant. Both methods are not the same, and the difference is not only speed of cloning. The crash consistent method can be used for any virtual machine, not only for those with Fault Tolerance enabled. The application consistent method is available for both Windows and Linux operating systems, not only for Linux. References: Clone a virtual machine; HPE SimpliVity frequently asked questions, page 17; Using HPE SimpliVity Official Certification Study Guide, page 65

 According to the HPE SimpliVity Solution Design Guide1, Lanamark is a cloud-based service that collects and analyzes data from customer environments to support the solution design process. Lanamark can collect data from various sources, such as vCenter Server, Hyper-V, XenServer, physical servers, and storage arrays. However, if the customer environment is not connected to the internet, Lanamark Snap can be used to collect the data offline and then upload it manually to the Lanamark portal. Lanamark Snap is a portable tool that can be downloaded from the Lanamark portal and run on any Windows workstation that has access to the customer environment. Lanamark Snap can connect to the vCenter Server and collect the performance data from the ESXi hosts and virtual machines. Lanamark Snap can also collect data from other sources, such as physical servers and storage arrays, by using agents or scripts. Lanamark Snap saves the collected data in a compressed file that can be uploaded to the Lanamark portal for analysis and reporting.

Therefore, the correct answer is D. Download Lanamark Snap and use it to collect the data, and then upload manually to the Lanamark portal, as this is the best option to collect data from an ESXi infrastructure that is not connected to the internet. References:

 According to the HPE SimpliVity REST API Reference Guide1, the svtcli account is a local emergency account that can be used to access HPE SimpliVity data using REST API whenthe hypervisor-based user is unavailable. This account can only perform a limited set of operations, such as getting information about hosts, clusters, backups, datastores, and virtual machines, and restoring backups of virtual machines. The svtcli account can request an authentication token using the emergency grant type, which is valid for 10 minutes of inactivity or 24 hours of continuous activity. The other options are not correct because:

• The svtcli account is not used when two or more VCs are not available. In that case, the federation management is transferred to the remaining VCs2.
• The svtcli account is not used when the hypervisor-based user is unavailable. In that case, the emergency grant type is used to access the REST API using the svtcli account1.
• The svtcli account is not used for daily management tasks performed using CLI. For that purpose, the hypervisor-based user is used, which has full access to the CLI commands3. References: 1: HPE SimpliVity REST API Reference Guide (A00019351ENW), pages 9-10, 14-152: HPE SimpliVity Administration Guide (A00019350ENW), page 303: HPE SimpliVity CLI Reference Guide (A00019352ENW), page 9.

Before moving a virtual machine to another datastore, you need to take a snapshot of the virtual machine using the HPE SimpliVity plugin in vSphere. This ensures that the virtual machine is in a consistent state and that the data is protected. The snapshot also serves as a backup in case the move operation fails or is interrupted. After taking the snapshot, you can use the HPE SimpliVity move operation to move the virtual machine to the desired datastore, either within the same cluster or across clusters. The move operation preserves the data efficiency and resiliency of the virtual machine, and does not require any downtime or reconfiguration12. References: Move a virtual machine to another datastore - Hewlett Packard Enterprise, HPE SimpliVity frequently asked questions

HPE SimpliVity provides storage HA by creating two copies of each virtual machine data across different nodes in a cluster. This ensures that the virtual machines can continue to run even if one node fails. However, this also consumes twice the storage capacity for each virtual machine. For development virtual machines that do not require storage HA, the customer can save storage capacity by creating a single-replica datastore for these virtual machines. A single-replica datastore is a datastore that has only one copy of the virtual machine data on one node. This reduces the storage consumption by 50%, but also increases the risk of data loss and unavailability in case of node failure. Therefore, the customer should carefully weigh the trade-offs between storage efficiency and data protection when using a single-replica datastore. References: HPE SimpliVity Data Virtualization Platform; HPE SimpliVity User Guide
