VMware VMware Certifications 5V0-22.23 Questions & Answers

• Question 31:

  In which type of environment is vSAN storage used as a mandatory, primary storage?

  A. VMware Cloud on AWS

  B. VMware Horizon

  C. VMware Aria Automation

  D. TanzuKubernetes Grid Integrated Edition

  Correct Answer: A

  Explanation: VMware Cloud on AWS is a service that delivers a fully managed VMware SDDC on AWS infrastructure. It uses vSAN as the mandatory, primary storage for the SDDC clusters. vSAN provides a high-performance, resilient, and secure shared storage solution for the VMware Cloud on AWS environment. The other options are not correct, as vSAN is not mandatory or primary for them. VMware Horizon, VMware Aria Automation, and Tanzu Kubernetes Grid Integrated Edition can use vSAN as an optional or secondary storage solution, but they can also use other types of storage.

• Question 32:

  An administrator is responsible for managing a five-node vSAN cluster. The vSAN Cluster is configured with both vSphere High Availability (HA) and vSphere Distributed Resource Scheduler (DRS). The vSAN Cluster is currently hosting 150

  virtual machines that have consumed 60% of the usable capacity.

  Each virtual machine belongs to one of the following vSAN Storage Policies:

  vSANPolicy1:

  Site Disaster Tolerance: None

  Failures to Tolerate: 1 failure - RAID-5 (Erasure Coding)

  vSANPolicy2:

  Site Disaster Tolerance: None

  Failures to Tolerate: No data redundancy

  Following an unplanned power event within the data center, the administrator has been alerted to the fact that one host has permanently failed.

  What will be the impact to any virtual machine that was running on the failed host using vSANPolicy1?

  A. Each virtual machine will be restarted on another vSAN host usingvSphere HA.

  B. Each virtual machine will be unavailable for up to 90 minutes while the automatic recovery process completes.

  C. vSAN will defer the start of the recovery process for 60 minutes, and the virtual machines will not power on until the recovery process has been completed.

  D. Each virtual machine must be restored from backup.

  Correct Answer: A

  Explanation: The impact to any virtual machine that was running on the failed host using vSANPolicy1 is that each virtual machine will be restarted on another vSAN host using vSphere HA. This is because vSANPolicy1 has a Failures to Tolerate setting of 1 failure - RAID-5 (Erasure Coding), which means that each object has four components (three data and one parity) distributed across four hosts. If one host fails, the object can still be accessed with the remaining three components,and vSphere HA will restart the virtual machine on another host. vSAN will also try to rebuild the missing component on another host, if there is enough capacity and resources. The other options are incorrect because they either assume that the object is unavailable or that the recovery process is delayed or impossible.

• Question 33:

  The Resyncing Objects view in the vCenter UI reports that some objects are currently resyncing. Which two actions would cause this situation? (Choose two.)

  A. A change to the storage policy is applied to the objects.

  B. DRS is relocatingVMs between vSAN nodes.

  C. A host failure occurs in the cluster

  D. HA Virtual Machine Monitoring forced a VM to reboot.

  E. VM snapshot is being deleted.

  Correct Answer: AC

  Explanation: Two actions that would cause some objects to be currently resyncing are: A change to the storage policy is applied to the objects. This action triggers a resynchronization of objects to make them compliant with the new policy settings, such as FTT, RAID level, stripe width, etc. The resynchronization process copies data from one host to another to create or update replicas or parity segments. A host failure occurs in the cluster. This action causes some objects to become non-compliant with their storage policy, as they lose one or more replicas or parity segments due to the host failure. The resynchronization process rebuilds the missing components on other hosts in the cluster to restore compliance and availability.References: : VMware vSphere Storage Guide, page 129 : Monitor the Resynchronization Tasks in the vSAN Cluster 1 : VMware vSAN Specialist v2 Exam Preparation Guide, page 13

• Question 34:

  A vSAN administrator needs to build a vSAN ESA cluster with RAID-5/FTT 1 adaptive storage policy. What is the absolute minimum number of hosts that need to be part of that vSAN ESA cluster?

  A. 6 hosts

  B. 4 hosts

  C. 5 hosts

  D. 3 hosts

  Correct Answer: D

  Explanation: To build a vSAN ESA cluster with RAID-5/FTT 1 adaptive storage policy, the absolute minimum number of hosts that need to be part of that vSAN ESA cluster is 3. This is because the vSAN ESA supports a new RAID-5 erasure coding scheme in a 2+1 configuration, which writes the data in a VM as a stripe consisting of 2 data bits and 1 parity bit, across a minimum of 3 hosts. This scheme can tolerate a single host failure (FTT=1) while consuming 1.5x the capacity of the primary data. This scheme is suitable for smaller vSAN clusters that want to reduce capacity usage without compromising performance12 References: 1: VMware vSAN Specialist v2 ExamPreparation Guide, page 15 2: Adaptive RAID5 Erasure Coding with the Express Storage Architecture in vSAN 8 3

• Question 35:

  An organization wants to implement a virtual desktop infrastructure (VDI) solution on their vSAN storage. They also need to store their applications running inside the VDI environment on vSAN storage. Which two end-user computing (EUC) solutions could be implemented to satisfy the requirements of the organization? (Choose two.)

  A. Agp_ Volumes

  B. Workspace ONE Access

  C. Horizon

  D. Workspace ONE UEM

  E. Dynamic Environment Manager

  Correct Answer: CE

  Explanation: Horizon and Dynamic Environment Manager are two end-user computing (EUC) solutions that can be implemented on vSAN storage to provide a virtual desktop infrastructure (VDI) solution and store applications running inside the VDI environment. Horizon is a platform that delivers virtual desktops and applications across a variety of devices and locations, while Dynamic Environment Manager is a tool that provides personalization and dynamic policy configuration across any virtual, physical, and cloud- based Windows desktop environment. The other solutions are not directly related to VDI or application storage on vSAN.

• Question 36:

  A vSAN administrator needs to update vSAN from version 7.0.2 to version 8.0. Which is the correct order to perform the update?

  A. vSphere -> vCenter -> vSAN on-disk format

  B. vSphere -> vSAN on-disk format -> vCenter

  C. vCenter -> vSphere -> vSAN on-disk format

  D. vSAN on-disk format -> vSphere -> vCenter

  Correct Answer: C

  Explanation: The correct order to perform the update from vSAN version 7.0.2 to version 8.0 is to upgrade the vCenter Server first, then upgrade the ESXi hosts, and finally upgrade the vSAN on-disk format. This order follows the general vSphere upgrade order, which ensures compatibility and interoperability between different components. Upgrading the vCenter Server first allows it to manage and monitor the ESXi hosts and the vSAN cluster during the upgrade process. Upgrading the ESXi hosts second ensures that they have the latest software patches and drivers for vSAN. Upgrading the vSAN on-disk format last enables the new features and functionality of vSAN 8.0. The other options are not correct, as they do not follow the recommended upgrade order.

• Question 37:

  All of the virtual machines running on a hybrid vSAN datastore have this storage policy assigned:

  Failures to Tolerate (FTT) rule is set to "2 Failures - RAID-1 (Mirroring)"

  The vSAN administrator needs to reduce the amount of vSAN datastore capacity the virtual machines will consume.

  Which action should the vSAN administrator take to meet this goal?

  A. Modify the FTT rule to "2 Failures - RAID-5 (Erasure Coding)"

  B. Add the "Flash read cache reservation" rule to the storage policy, and set to 0%

  C. Disable Operations reserve and Host rebuild reserve and click "Apply"

  D. Change the FTT rule to "1 Failure - RAID-1 (Mirroring)", and select "Now" for Reapply to VMs

  Correct Answer: D

  Explanation: To reduce the amount of vSAN datastore capacity the virtual machines will consume, the vSAN administrator should change the FTT rule to "1 Failure - RAID-1 (Mirroring)", and select "Now" for Reapply to VMs. This action will reduce the number of replicas for each object from three to two, and thus free up some space on the vSAN datastore. The other options are not correct, as they will not reduce the capacity consumption. Modifying the FTT rule to "2 Failures RAID-5 (Erasure Coding)" will not work for a hybrid vSAN cluster, as erasure coding is only supported for all-flash clusters. Adding the "Flash read cache reservation" rule to the storage policy, and setting to 0% will not affect the capacity layer, as it only controls the amount of flash cache reserved for each object. Disabling Operations reserve and Host rebuild reserve and clicking "Apply" will not change the actual space used by the objects, as these reserves are only logicalsettings that affect how much free space is reported by vSAN. References: 1, page 9; , section 4.3

• Question 38:

  Refer to the exhibit.

  An administrator uses SSH to log into a vSAN ESA host and runs theesxcli vsan debug object overviewcommand.

  

  The administrator notices the Healthy Components column, the last column, is reporting some components are not in a fully healthy state.

  What could cause this behavior?

  A. New physical disks have been claimed and a rebalance operation is underway.

  B. The applied Storage policy has been updated.

  C. New VMDKs have been added to multiple VMs, but the storage policy has not finished applying.

  D. One host is in maintenance mode with ensure accessibility.

  Correct Answer: D

  Explanation: The most likely cause for some components to be not in a fully healthy state is that one host is in maintenance mode with the ensure accessibility option. This option creates temporary durability components on other hosts to maintain the required number of failures to tolerate (FTT) until the original components are restored or rebuilt. These durability components are not considered fully healthy because they do not have full redundancy and might not be compliant with the storage policy. The other options do not explain why some components are not fully healthy, as they do not affect the FTT or the compliance state of the objects.

• Question 39:

  After reviewing various performance charts at a cluster level, an administrator found an individual VM impacting overall performance of the vSAN cluster.

  What feature should be used to introspect multiple performance metrics of a single virtual machine?

  A. esxci

  B. Skyline Health

  C. I/O Trip Analyzer

  D. llOlnsiqht

  Correct Answer: C

  Explanation: To introspect multiple performance metrics of a single virtual machine, such as latency, throughput, IOPS, and congestion, the feature that should be used is I/O Trip Analyzer. This feature allows the administrator to diagnose the virtual machine I/O latency issues by providing a breakdown of the latencies at each layer of the vSAN stack, such as VM, host, network, and disk group. The other options are not correct, as they do not provide multiple performance metrics of a single virtual machine. esxcli is a command-line tool that can be used to manage various aspects of ESXi hosts, but it does not provide detailed performance analysis of virtual machines. Skyline Health is a feature that provides proactive notifications and recommendations for software and hardware issues based on VMware Analytics Cloud, but it does not provide granular performance metrics of virtual machines. llOlnsiqht is not a valid feature name in vSAN.

• Question 40:

  An application refactor requires significant storage that is being added for logs stored on a VM vDISK. The application VMs run on a dedicated vSAN enabled vSphere Cluster with custom CPUs and RAM, and therefore, cannot vMotion to another vSAN enabled cluster.

  The administrator needs a vSAN feature that can be used to allocate additional storage from another vSAN enabled vSphere cluster to this vSAN enabled Cluster.

  Which vSAN feature should be used for this purpose?

  A. vSAN File Services

  B. vSAN HCI Mesh

  C. vSAN Replication

  D. vSAN Stretched Clusters

  Correct Answer: B

  Explanation: To allocate additional storage from another vSAN enabled vSphere cluster to this vSAN enabled Cluster, the administrator should use the vSAN HCI Mesh feature. This feature allows a vSAN cluster to consume storage resources from another vSAN cluster without requiring the hosts to be part of the same cluster. This way, the administrator can leverage the unused or underutilized storage capacity from another cluster and avoid purchasing new hardware or migrating VMs. The vSAN HCI Mesh feature also supports storage policies, encryption, deduplication and compression, and erasure coding across clusters12 References: 1: VMware vSAN Specialist v2 Exam Preparation Guide, page 15
