VMware VMware Certifications 5V0-22.23 Questions & Answers

• Question 61:

  When adding a disk to a host that was previously used in a decommissioned vSAN cluster the intended disk does not show among the available devices in disk management.

  Which action should be taken prior to assigning the disk on disk management?

  A. Format the existing partition

  B. Create a 1GB metadata partition

  C. Delete all device partitions

  D. Create a VMFS partition

  Correct Answer: C

  Explanation: When adding a disk to a host that was previously used in a decommissioned vSAN cluster, the disk may still have some vSAN metadata partitions that prevent it from being recognized by disk management. To resolve this issue, the disk partitions need to be deleted using either ESXCLI or partedUtil commands. This will erase all data on the disk and make it available for use in disk management.

• Question 62:

  A vSAN administrator of a non-internet connected vSAN environment wants to upgrade the environment from the vSAN 7.0 U3 to the vSAN 8.0 using vLCM.

  Which option, if any, should be used as a depot in this case?

  A. Configure the vSphere Lifecycle Manager to download the updates from an Online Depot.

  B. Configure the vSphere Lifecycle Manager to download the updates from the VMware Depot using HTTPS.

  C. Configure the vSphere Lifecycle Manager to download updates from a local UMDS- shared repository.

  D. It is not possible to use the vSphere Lifecycle Manager on a non-internet connected environment.

  Correct Answer: C

  Explanation: To upgrade the vSAN environment from vSAN 7.0 U3 to vSAN 8.0 using vLCM in a non-internet connected environment, the administrator should configure the vSphere Lifecycle Manager to download updates from a local UMDS-shared repository. UMDS stands for Update Manager Download Service, which is a component of vSphere Lifecycle Manager that can be used to download patches and updates for ESXi hosts, virtual appliances, and VMware Tools from the VMware online depot and store them in a shared repository. The administrator can then configure the vSphere Lifecycle Manager to use the UMDS-shared repository as a custom depot for patching and upgrading the vSAN cluster. This option allows the administrator to perform offline upgrades without requiring internet access for the vSAN cluster12 References: 1: VMware vSphere Lifecycle Manager Administration, page 22 2: VMware vSphere Update Manager Download Service, page 5

• Question 63:

  An administrator is deploying a new two-node vSAN cluster with a shared witness to a remote location.

  Which requirement must be met?

  A. The ESXi hosts must have SSDs or NVMe configured for Virtual Flash File System.

  B. The ESXi host's controller cache and advanced features must be disabled.

  C. The ESXi host's drives must be configured in RAID 1 to support Failures to Tolerate of 1.

  D. The ESXi hosts must have a minimum of 64 GBs of memory.

  Correct Answer: D

  Explanation: To deploy a new two-node vSAN cluster with a shared witness, the administrator must meet several requirements, one of which is that the ESXi hosts must have a minimum of 64 GBs of memory. This is because each host must have enough memory to run the VMs and also to support the vSAN metadata overhead. The other options are not requirements for a two-node vSAN cluster with a shared witness. The ESXi hosts do not need SSDs or NVMe for Virtual Flash File System, as they can use any supported storage devices for vSAN. The ESXi host's controller cache and advanced features do not need to be disabled, as they can be used to improve performance and reliability. The ESXi host's drives do not need to be configured in RAID 1, as vSAN uses its own software-defined RAID mechanism to provide Failures to Tolerate.

• Question 64:

  A vSAN administrator has an existing cluster where each ESXi host has the following:

  Disk group #1 with one cache device and three capacity devices. Disk group #2 with one cache device and two capacity devices.

  What must the vSAN administrator do to expand disk group #2 to have three capacity devices?

  A. Create a new disk group with a single capacity device and then migrate the existing capacity devices

  B. Add the new capacity device to the disk group and vSAN will automatically rebalance

  C. Put the entire ESXi host in maintenance mode, evacuate all data, then add the new capacity device

  D. Put the disk group in maintenance mode, evacuate all data, then add the new capacity device

  Correct Answer: B

  Explanation: To expand disk group #2 to have three capacity devices, the vSAN administrator should add the new capacity device to the disk group and vSAN will automatically rebalance. This action allows the administrator to increase the storage capacity of the disk group without disrupting any ongoing operations or evacuating any data. vSAN will automatically distribute data across all devices in the disk group to balance performance and utilization. The other options are not correct. Creating a new disk group with a single capacity device and then migrating the existing capacity devices is not necessary, as it would require more steps and resources than adding a device to an existing disk group. Putting the entire ESXi host or the disk group in maintenance mode and evacuating all data is not required, as it would cause downtime and data movement that could be avoided by adding a device to an existing disk group.

• Question 65:

  Due to a planned power outage, an administrator decides to shut down the vSAN cluster using the Shutdown Cluster Wizard. The administrator starts by checking the vSAN health service to confirm the cluster is healthy and then powers off all virtual machines (VMs) including vCLS VMs.

  Which step needs to be taken before starting the Shutdown Cluster Wizard?

  A. Place all ESXi hosts into maintenance mode

  B. Disable cluster member updates from vCenter Server

  C. Turn off High Availability

  D. Shutdown vCenter

  Correct Answer: C

  Explanation: To shut down the vSAN cluster using the Shutdown Cluster Wizard, the administrator needs to turn off High Availability (HA) before starting the wizard. This is because HA monitors the cluster for host failures and attempts to restart the affected VMs on other hosts. If HA is not turned off, the cluster might register host shutdowns as failures and trigger unnecessary VM restarts, which can interfere with the graceful shutdown process. Therefore, the administrator should disable HA from the Configure tab of the cluster before using the Shutdown Cluster Wizard12 References: 1: Shut Down the vSAN Cluster Using the Shutdown Cluster Wizard 3 2: Manually Shut Down and Restart the vSAN Cluster 4

• Question 66:

  Which two considerations should an architect assess when designing a HCI Mesh solution with VMware vSAN and VMware vSphere High Availability (HA)? (Choose two.)

  A. A server vSAN cluster can serve its local datastore up to five client vSAN clusters.

  B. A client cluster can mount up to ten remote datastores from one or more vSAN server clusters.

  C. A minimum of three nodes are required within the client cluster for vSphere HA to work

  D. If vSphere HA is to work with HCI Mesh, Datastore with Permanent Device Loss (PDL) must be confiqured to Power off and restart VMs.

  E. If vSphere HA is to work with HCI Mesh, Datastore with AllPaths Down (APD) must be configured to Power off and restart VMs.

  Correct Answer: CE

  Explanation: To design a HCI Mesh solution with VMware vSAN and VMware vSphere High Availability (HA), two considerations that the architect should assess are: A minimum of three nodes are required within the client cluster for vSphere HA to work. This is because vSphere HA needs at least three nodes in a cluster to form a quorum and elect a master host that monitors the availability of other hosts and VMs. If there are less than three nodes in a cluster, vSphere HA cannot function properly and might fail to detect or respond to host or VM failures. If vSphere HA is to work with HCI Mesh, Datastore with All Paths Down (APD) must be configured to Power off and restart VMs. This is because APD is a condition that occurs when a storage device becomes inaccessible due to loss of physical connectivity, resulting in I/O errors or timeouts for VMs that use that device. When using HCI Mesh, APD can happen if the network connection between the client cluster and the server cluster is lost or disrupted, causing the remote datastore to become unavailable. To ensure that vSphere HA can restart the affected VMs on another host that has access to their storage, Datastore with APD must be set to Power off and restart VMs in the vSphere HA settings. The other options are not correct. A server vSAN cluster can serve its local datastore up to 15 client vSAN clusters, not five. This is the maximum number of client clusters that can mount a remote datastore from a server cluster using HCI Mesh. A client cluster can mount up to five remote datastores from one or more vSAN server clusters, not ten. This is the maximum number of remote datastores that can be mounted by a client cluster using HCI Mesh.

• Question 67:

  A vSAN administrator has two identical VMware vSAN clusters, one for staging workloads and another for production workloads. Due to an unforeseen capacity requirement, the vSAN administrator is tasked with merging the staging vSAN cluster into the production.

  Which three actions should the vSAN administrator perform on the staging cluster prior to moving the vSAN nodes to the production cluster? (Choose three.)

  A. Disable vSAN Services

  B. Delete all Disk Groups

  C. Enable File Services

  D. Delete all partitions from the capacity disks

  E. Mark the disks for partial reservation

  F. Remove all capacity drives

  Correct Answer: ABD

  Explanation: The three actions that the vSAN administrator should perform on the staging cluster prior to moving the vSAN nodes to the production cluster are: Disable vSAN Services: This will stop any vSAN-related operations on the staging cluster, such as resynchronization, rebalancing, or repair. This will also prevent any new virtual machines from being created or migrated to the staging cluster. Delete all Disk Groups: This will remove all disks from the vSAN cluster and erase all data on them. This will also free up the disks for use in the production cluster. Delete all partitions from the capacity disks: This will ensure that there are no remnants of any previous vSAN configuration on the disks. This will also avoid any potential conflicts or errors when adding the disks to the production cluster. Enabling File Services, marking the disks for partial reservation, and removing all capacity drives are not necessary or recommended actions for this scenario. Enabling File Services would add an unnecessary layer of complexity and overhead to the staging cluster. Marking the disks for partial reservation would reduce the available capacity for vSAN and potentially cause performance issues. Removing all capacity drives would leave only cache disks in the staging cluster, which would not be compatible with vSAN. References: VMware vSAN Specialist v2 Exam Preparation Guide, page 10

• Question 68:

  A customer wishes to host a new range of applications with high-performance requirements, specifically, low latency. The current vSAN platform is based on ReadyNode hardware and uses a vSAN 7.0 U2 hybrid topology configuration.

  Which would satisfy the customer's requirement?

  A. Deploy the application on a new cluster with vSAN 8.0 ESA using a new hardware design

  B. Deploy the new applications on the existing cluster with a RAID-6 VM storage policy and an additional stripe width of 4

  C. Deploy the application on a new cluster with vSAN 8.0 OSA using the existing hybrid configuration

  D. Perform an in-place upgrade from vSAN 7.0 U2 OSA to vSAN 8.0 ESA

  Correct Answer: A

  Explanation: Deploying the application on a new cluster with vSAN 8.0 ESA using a new hardware design is the correct answer because it will satisfy the customer's requirement for low latency. vSAN 8.0 ESA is a new architecture that uses a storage pool configuration where all disks are treated as capacity disks and use a new algorithm to distribute data across them. This improves the I/O flow, reduces the write amplification, and eliminates the cache tier bottleneck. Using a new hardware design with all-flash disks or NVMe disks will further enhance the performance and latency of the application, as these disks have faster read and write speeds than hybrid disks. Deploying the new applications on the existing cluster with a RAID-6 VM storage policy and an additionalstripe width of 4, deploying the application on a new cluster with vSAN 8.0 OSA using the existing hybrid configuration, and performing an in-place upgrade from vSAN 7.0 U2 OSA to vSAN

  8.0 ESA are not valid or optimal solutions for this scenario. Deploying the new applications on the existing cluster with a RAID-6 VM storage policy and an additional stripe width of 4 will increase the resiliency and availability of the data, but it will also increase the network traffic, disk space consumption, and parity calculation overhead, which will negatively affect the latency and performance of the application. Deploying the application on a new cluster with vSAN 8.0 OSA using the existing hybrid configuration will not improve the latency significantly, as vSAN 8.0 OSA still uses the same disk group configuration as vSAN 7.0 U2 OSA, where one disk is designated as a cache disk and the rest are capacity disks. The cache disk can still become a bottleneck for high-performance applications, especially if it is not an SSD or NVMe disk. Performing an in-place upgrade from vSAN 7.0 U2 OSA to vSAN 8.0 ESA is not possible, as vSAN ESA requires a different hardware design than vSAN OSA. The existing disk groups need to be deleted and all disks need to be erased before switching to vSAN ESA.

• Question 69:

  A vSAN administrator wants to transition from VMware Update Manager to vSphere Lifecycle Manager. Which element is a mandatory requirement to create an image?

  A. ESXi Version

  B. Component

  C. Firmware and Drivers Add-On

  D. Vendor Add-On

  Correct Answer: A

  Explanation: To create an image using vSphere Lifecycle Manager, the mandatory requirement is to specify the ESXi version. An image is a collection of software components that define the desired state of hosts in a cluster. An image must include at least one ESXi version component, which determines the base hypervisor software for the hosts. Optionally, an image can also include other components, such as vendor add-ons, firmware and drivers add-ons, or custom components. The other options are not correct. A component is a generic term for any software element that can be included in an image, but it is not a specific type of component. A firmwareand drivers add-on is an optional component that provides firmware and drivers updates for hardware devices on the hosts. A vendor add-on is an optional component that provides vendor-specific software for the hosts. References: About Images; Create an Image

• Question 70:

  An administrator has 24 physical servers that need to be configured with vSAN. The administrator needs to ensure that a single rack failure is not going to affect the data availability. The number of racks used should be minimized.

  What has to be done and configured to achieve this goal?

  A. Distribute servers across at least two different racks and configure two fault domains

  B. Configure disk groups with a minimum of four capacity disks in each server and distribute them across four racks

  C. Enable deduplication and compression

  D. Distribute servers across at least three different racks and configure three fault domains

  Correct Answer: D

  Explanation: To ensure that a single rack failure is not going to affect the data availability, while minimizing the number of racks used, the administrator has to do the following: Distribute servers across at least three different racks. This is because vSAN supports up to three fault domains per cluster, which can be used to tolerate one or two failures. If only two racks are used, then only one failure can be tolerated4 Configure three fault domains. A fault domain is a logical grouping of hosts that share a common failure point, such as a rack or a power supply. By configuring fault domains, vSAN can place replicas of an object across different fault domains, so that a failure within one fault domain does not result in data loss orunavailability4 References: 4: VMware vSAN Specialist v2 Exam Preparation Guide, page 13
