VMware HCI Master Specialist Questions and Answers
Upon checking the latency goal under vSAN performance diagnostics, the vSAN Administrator sees this message displayed:
The increase in latency in the vSAN stack might be beyond expected limits.
Which two root causes can be identified to help remediate the issue? (Choose two.)
An administrator wants to enable encryption on an existing vSAN cluster that already contains virtual machines.
Which additional step should the administrator take to ensure no data is lost during the encryption process?
A customer is planning to migrate their physical Microsoft SQL Server clustered workloads to vSAN enabled vSphere clusters.
The following requirements must be met:
* Each MSSQL cluster is made up of 3 nodes
* Highest possible availability against node failures
* Some of the vSAN clusters will only consume storage
What should the architect recommend?
An architect is designing a vSAN cluster.
Which storage controller option will yield optimal performance?
A company has engaged a consultant to upgrade an existing vSAN cluster to vSAN 7.0 U1. The company wants to ensure that the same vSAN process can be used in the future.
During the discovery phase, the consultant found the following information about the existing environment:
* The vCenter Server is currently version 7.0.
* The vSAN Cluster has the following configuration:
- vSAN version: 7.0
- Number of vSAN nodes: 6
- Encryption: enabled
- Deduplication and Compression: enabled
- Fault Domains: 1
- vSAN Capacity Utilization: 60%
* Each vSAN node has the following configuration:
- ESXi version: VMware vSphere 7.0
- CPU: 2 processors, 20 cores
- RAM: 1024GB RAM.
- Disk: 2 Cache SSDs and 6 Capacity SSDs
- Network: 4 x 10GbE
* All current hardware (which is from a single vendor) is listed on the vSAN Compatibility Guide for vSAN 7.
Which three recommendations should the consultant make to ensure that the vSAN cluster upgrade is completed? (Choose three.)
Which flash disk size is required for the cache tier per ESXi node to meet all requirements?
An architect needs to automate an infrastructure that supports VMware Horizon as well as VMware Tanzu.
Which solution mandates the use of VMware vSAN?
A company has deployed a 12-node (6-6-1) vSAN 7.0 stretched cluster for all production workloads.
The customer currently uses four different vSAN storage policies for running the workloads depending on the applications requirements:
* Policy 1 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Erasure Coding
* Policy 2 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Mirroring
* Policy 3 - Site Disaster Tolerance=None - Keep Data on Preferred, FTT=Mirroring
* Policy 4 - Site Disaster Tolerance=None - Keep Data on Non-Preferred, FTT=Mirroring
During the setup of the vSAN stretched cluster, the following VM/Host Rules were created:
* Preferred Site - Preferred Site workloads should run on DC1 hosts.
* Secondary Site - Secondary Site workloads should run on DC2 hosts.
Which two activities should the administrator complete to ensure that there is no impact to production services during the maintenance window in the Preferred Site? (Choose two.)
An administrator wants to deploy Kubernetes on an end-to-end VMware stack, using VMware vSAN for storage.
Which VMware product should the administrator install as the Kubernetes platform choice?
In a vSAN stretched cluster, which value must be set in the vSAN policy if there is no requirement for data mirroring across sites?
An administrator has noticed that a number of the virtual machines in the preferred site are showing as either failed or partitioned.
In which two ways would the administrator expect the virtual machines to respond? (Choose two.)
An architect intends to use the Primary Level of Failures To Tolerate (PFTT) to calculate the minimum number of required hosts for a vSAN cluster.
Which calculation model should be used?
An administrator is planning to change a vSAN Storage Policy to apply a Failures To Tolerate (FTT) of 2, using RAID-6.
What is the minimum number of vSAN nodes required?
An architect collected the below technical requirements from the customer during a vSAN cluster design workshop:
* Maximize the vSAN datastore usable capacity.
* Deduplication and compression are required to help utilize available capacity efficiency.
* Ensure the highest level of resiliency wherever possible.
Which disk group configuration should the architect include in the design?
An architect is working with an All-Flash vSAN configuration and will be using the Flash Caching Devices in vSAN.
Which requirement is specifically needed for these devices?
In a stretched vSAN cluster, how is Read Locality established after fail over to the secondary site?
An administrator is setting up vSAN file services on a vSAN cluster.
Which two security policies on the distributed port groups are automatically enabled in the process? (Choose two.)
An architect is tasked with designing a solution that includes the following requirements:
• The solution must support 5,000 virtual machines.
• The solution must include software defined storage.
• The deployment of the solution must be automated.
• The solution must provide storage-policy based disaster recovery for all workloads.
Which combination of three products will fulfill these requirements? (Choose three.)
A company has engaged a consultant to upgrade an existing vSAN cluster to vSAN 7.0 U1.
During the discovery phase, the consultant found the following information about the existing environment:
* The VMware vCenter Server has recently been upgraded from VMware vSphere 6.7 U3 to version 7.0 U1.
* The vSAN Cluster was recently expanded with identical hardware specification, but from a different hardware vendor.
* The hardware for each vSAN node is listed on the vSAN Compatibility Guide (VCG) for vSAN 7.
* The vSAN Cluster has the following configuration:
- vSAN version: 6.6.1
- Number of vSAN nodes: 10
- Encryption: enabled
- Deduplication and Compression: enabled
- vSAN Capacity Utilization: 60%
* Each vSAN node has the following configuration:
- VMware vSphere ESXi version: 6.5 Update 3
- CPU: 2 processors, 20 cores
- RAM: 768GB RAM.
- Disk: 2 Cache SSDs and 6 Capacity SSDs
- Network: 4 x 10GbE
Which three recommendations should the consultant make to ensure all data remains protected in the event of a vSAN failure? (Choose three.)
