VMware 5V0-22.23 Online Questions & Answers

• Question 1:

  After a server power failure, the administrator noticed the scheduled resyncing in the cluster monitor displays objects to be resynchronized under the pending category.

  Why are there objects in this category?

  A. The delay timer has not expired.
  B. These objects belong to virtual machines, which are powered off.
  C. Object resynchronization must be started manually.
  D. There are too many objects to be synchronized.
  A. The delay timer has not expired.

  ---

  explanation:

  Explanation/Reference:

  The reason why there are objects in the pending category of the scheduled resyncing in the cluster monitor is that the delay timer has not expired. The delay timer is a configurable setting that determines how long vSAN waits before repairing a non-compliant object after placing a host in a failed state or maintenance mode. The default value is 60 minutes, but it can be changed in the vSAN Services configuration. The pending category displays the objects with the expired delay timer that cannot be resynchronized due to insufficient resources in the current cluster or the vSAN FTT policy set on the cluster not being met. The other options are not correct. These objects do not belong to virtual machines that are powered off, as vSAN resynchronizes all objects regardless of their power state. Object resynchronization does not need to be started manually, as vSAN initiates it automatically when the delay timer expires. There are not too many objects to be synchronized, as vSAN can handle multiple resynchronization tasks in parallel.

• Question 2:

  What is the purpose of host rebuild reserve in vSAN?

  A. Reserves space for internal operations
  B. Reserves space in case of single host failure
  C. Stores vSphere HA heartbeats
  D. Allocates capacity for vCLS
  B. Reserves space in case of single host failure

  ---

  explanation:

  Explanation/Reference:

  The host rebuild reserve is a feature that allows vSAN to reserve space in the cluster for vSAN to be able to repair in case of a single host failure. This reservation is set to one host worth of capacity, which means that if one host in the vSAN cluster fails and no longer contributes storage, there is still sufficient capacity remaining in the cluster to rebuild and re-protect all vSAN objects. This feature prevents the creation of new VMs or powering on VMs if such operations consume the reserved space. By default, the host rebuild reserve is disabled, but it can be enabled in the vSAN Services configuration. The other options are not related to the hostrebuild reserve.

• Question 3:

  A vSAN administrator is using the vSAN ReadyNode Sizer to build a new environment. While entering the cluster configurations, a fellow colleague inquires about the Operations Reserve option.

  What is the purpose of using this option?

  A. Provides space for internal operations
  B. Configures space for external operations
  C. Reserves space for tolerating failures
  D. Allocates space forvSAN uparades
  A. Provides space for internal operations

  ---

  explanation:

  Explanation/Reference:

  The purpose of using the Operations Reserve option in the vSAN ReadyNode Sizer is to provide space for internal operations such as deduplication, compression, encryption, snapshots, clones, and rebalancing. The Operations Reserve is calculated as a percentage of the total usable capacity of the vSAN cluster. The default value is 30%, but it can be adjusted based on the expected workload characteristics and data services requirements. The other options are not correct, as they do not describe the Operations Reserve option. Configuring space for external operations, reserving space for tolerating failures, and allocating space for vSAN upgrades are not part of the Operations Reserve option.

• Question 4:

  An existing vSAN OSA cluster has this specification:

  Four ESXi hosts with all flash configuration Each with two disk groups Each disk group with one cache device and four capacity devices There are five more device slots available per host

  The CTO would like to provision new applications, and these will need more capacity and performance.

  Which two methods should be used by the vSAN administrator to meet this goal with the least amount of impact? (Choose two.)

  A. Replacing all capacity devices with a similar larger device
  B. Replacing all cache devices with a larger device
  C. Adding one more disk group per host with the same configuration
  D. Adding faster cache devices
  E. Adding an ESXi host with identical device configuration
  C. Adding one more disk group per host with the same configuration
  E. Adding an ESXi host with identical device configuration

  ---

  explanation:

  Explanation/Reference:

  Adding one more disk group per host with the same configuration and adding an ESXi host with identical device configuration are the two methods that the vSAN administrator should use to meet the goal of increasing capacity

  and performance with the least amount of impact. Adding one more disk group per host will increase the raw storage capacity by 20% and also improve the performance by distributing the I/O load across more cache devices and disk groups.

  Adding an ESXi host with identical device configuration will increase the raw storage capacity by 25% and also improve the performance by adding more compute and network resources to the cluster. Both methods can be done without

  disrupting any ongoing operations or requiring any data evacuation or resynchronization. The other options are incorrect for the following reasons:

  Replacing all capacity devices with a similar larger device is incorrect because it will not increase the performance and will have a significant impact on the cluster. Replacing the capacity devices requires deleting the disk groups, which will

  erase all data on them and trigger a resynchronization of the affected objects. This can be disruptive and time-consuming, and also introduce additional network and disk traffic.

  Replacing all cache devices with a larger device is incorrect because it will not increase the capacity and will have a significant impact on the cluster. Replacing the cache devices also requires deleting the disk groups, which will have the same drawbacks as replacing the capacity devices. Moreover, increasing the cache size may not improve the performance significantly, as vSAN OSA uses afixed cache ratio of 70% for write buffer and 30% for read cache, regardless of the cache device size. Adding faster cache devices is incorrect because it will not increase the capacity and will have a significant impact on the cluster. Adding faster cache devices also requires deleting the disk groups, which will have the same drawbacks as replacing the cache devices. Furthermore, adding faster cache devices may not improve the performance significantly, as vSAN OSA uses a fixed cache ratio of 70% for write buffer and 30% for read cache, regardless of the cache device speed.

• Question 5:

  The DevOps team of an organization wants to deploy with persistent storage on a dedicated vSAN cluster. The storage administrator is tasked to configure the vSAN cluster and leverage the vSAN Direct feature.

  Which two requirements must the administrator meet to complete this task? (Choose two.)

  A. A valid vSAN license for the vSAN cluster
  B. HA enabled on the vSAN cluster
  C. A dedicated network for vSAN Direct
  D. An integration with vSAN File Services
  E. Unclaimed disks in the hosts forvSAN Direct
  A. A valid vSAN license for the vSAN cluster
  E. Unclaimed disks in the hosts forvSAN Direct

  ---

  explanation:

  Explanation/Reference:

  To configure vSAN Direct, the administrator must meet two requirements: a valid vSAN license for the vSAN cluster and unclaimed disks in the hosts for vSAN Direct. A vSAN license is required to enable vSAN features and services, including vSAN Direct. Unclaimed disks are local storage devices that are not used by vSAN or any other service, and can be claimed by vSAN Direct to create datastores for persistent storage. The other options are not requirements for vSAN Direct. HA is an optional feature that can be enabled on any cluster, but is not specific to vSAN Direct. A dedicated network for vSAN Direct is not necessary, as vSAN Direct uses the same network as vSAN. An integration with vSAN File Services is not required, as vSAN Direct does not provide file shares, but block storage. References: Set Up vSAN Direct for vSphere with Tanzu; vSAN Licensing Guide

• Question 6:

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

  ---

  explanation:

  Explanation/Reference:

  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

• Question 7:

  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
  A. ESXi Version

  ---

  explanation:

  Explanation/Reference:

  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 8:

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

  ---

  explanation:

  Explanation/Reference:

  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 9:

  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
  A. Disable vSAN Services
  B. Delete all Disk Groups
  D. Delete all partitions from the capacity disks

  ---

  explanation:

  Explanation/Reference:

  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 10:

  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.
  C. A minimum of three nodes are required within the client cluster for vSphere HA to work
  E. If vSphere HA is to work with HCI Mesh, Datastore with AllPaths Down (APD) must be configured to Power off and restart VMs.

  ---

  explanation:

  Explanation/Reference:

  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. References: VMware vSAN HCI Mesh; vSphere Availability; Handling All Paths Down (APD) Conditions
