  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.

• Question 72:

  A six-node vSAN ESA cluster contains multiple virtual machines, and a vSAN storage policy with the rule "Failures to tolerate" set to "1 failure - RAID-5 (Erasure Coding)" is assigned. A vSAN administrator has changed the rule in the assigned policy to "2 failures - RAID-6 (Erasure Coding)".

  What is the result of this change?

  A. No changes occur until the policy is reapplied.
  B. The changes are queued for 60 minutes.
  C. The policy change is rejected immediately.
  D. The updated policy is serially applied to the virtual machines.
  D. The updated policy is serially applied to the virtual machines.

  ---

  Explanation/Reference:

  The updated policy is serially applied to the virtual machines is the correct answer because changing the rule in the assigned policy will trigger a policy compliance check and a resynchronization of the affected objects. The policy change will not be rejected, queued, or ignored, as it is a valid and supported operation. However, the policy change will not be applied in parallel, as that would cause too much network and disk traffic. Instead, the policy change will be applied one virtual machine at a time, starting with the most critical ones, until all virtual machines are compliant with the new policy.

• Question 73:

  Which VMware solution requires vSAN usage?

  A. VMware Cloud Foundation
  B. VMware Horizon
  C. VMware Telco Cloud Automation
  D. VMware Aria Automation
  A. VMware Cloud Foundation

  ---

  Explanation/Reference:

  The VMware solution that requires vSAN usage is VMware Cloud Foundation. VMware Cloud Foundation is an integrated software stack that bundles compute virtualization (VMware vSphere), storage virtualization (VMware vSAN), network virtualization (VMware NSX), and cloud management and monitoring (VMware vRealize Suite) into a single platform that can be deployed on premises or as a service within a public cloud. VMware Cloud Foundation relies on vSAN as the primary storage solution for its workload domains, which are logical pools of resources that can be used to run different types of workloads. The other options are not correct. VMware Horizon, VMware Telco Cloud Automation, and VMware Aria Automation are VMware solutions that do not require vSAN usage, although they can benefit from it. VMware Horizon is a platform that delivers virtual desktops and applications across a variety of devices and locations, and it can use any supported storage solution, including vSAN. VMware Telco Cloud Automation is a cloud-native orchestration and automation platform that enables communication service providers to accelerate the deployment and lifecycle management of network functions and services across any network and cloud. It can use any supported storage solution, including vSAN. VMware Aria Automation is not a valid VMware solution name.

• Question 74:

  What is the minimum required number of hosts to provide data redundancy for a vSAN stretched cluster using dual-site mirroring and local protection with 1 failure - RAID-1 (Mirroring)?

  A. 3 hosts
  B. 3 hosts
  C. 4 hosts
  D. 6 hosts
  D. 6 hosts

  ---

  Explanation/Reference:

  The minimum required number of hosts to provide data redundancy for a vSAN stretched cluster using dual-site mirroring and local protection with 1 failure - RAID-1 (Mirroring) is six hosts. This is because a vSAN stretched cluster requires at least three hosts per site, and each site must have enough hosts to tolerate one host failure. Therefore, the minimum configuration is three hosts per site, plus one witness host at a third site, for a total of six hosts. References: [VMware vSAN Specialist v2 EXAM 5V0- 22.23], page 14

• Question 75:

  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/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.
