1In a stretched vSAN cluster, how is Read Locality established after fail over to the secondary site?
  • 100% of the reads comes from vSAN hosts on the local site
  • 50% of the reads comes from vSAN hosts on the local site
  • 100% of the reads comes from vSAN hosts on the remote site
  • 50% of the reads comes from vSAN hosts on the remote site
Answer: A
2During a maintenance action on a vSAN node, a vSAN administrator noticed that the default repair delay time is about to be reached. Which two commands must be run to extend the time? (Choose two.)
  • /etc/init.d/vsanmgmtd restart
  • esxcli system settings advanced set -o /VSAN/ClomRepairDelay -i 50
  • esxcli system settings advanced set -o /VSAN/ClomRepairDelay -i 80
  • /etc/init.d/clomd restart
  • /etc/init.d/vsanobserver restart
Answer:
3A write intensive application has been deployed recently into an All-flash 4-node vSAN cluster. Each node has one disk group with the following configuration: • 1 x 400 GB SSD for Cache • 4 x 3.84 TB SSD for Capacity After the deployment, the administrator notices that the overall workload performance is degraded and observes a low-write, buffer-free percentage. Which action should be taken to remediate this issue?
  • Adding a second cache disk to the existing disk group
  • Replacing the cache disk in the existing disk group with a larger one
  • Enabling automatic rebalance from the vSAN services advanced options
  • Increasing the number of capacity disks in the existing disk group
Answer: B
4An administrator wants to deploy a desktop and application virtualization solution on top of vSAN. Which VMware product should the administrator install?
  • VMware Dynamic Environment Manager
  • VMware Horizon Apps
  • VMware Workspace One Access
  • VMware Horizon
Answer: D
5An administrator has been tasked with enabling encryption for existing virtual machines on a vSAN cluster. Which three prerequisites must be satisfied before completing the task? (Choose three.)
  • Create an encryption storage policy
  • Enable Data-In-Transit encryption first
  • Enable that the virtual machines are powered on
  • Verify if a role with privilege ג€Cryptographic operations.Encrypt newג€ is assigned
  • Verify if a role with privilege ג€Cryptographic operations.Migrateג€ is assigned
  • Establish a trusted connection with the KMS
Answer:
6Upon 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.)
  • vSAN VMKemel portgroup is configured with the ג€Route based on IP hashג€ teaming policy
  • vSAN encryption is enabled
  • Large packet losses and retransmissions on the network layer
  • Incorrect sizing of the disk groups capacity disks
  • One or more disk groups are congested
Answer:
7An architect is designing for a production vSAN cluster, and the customer introduced these requirements related to File Services: ✑ A minimum of 12 files shares. ✑ 30TB NFS capacity to mount workload VMs. What should be the architect's recommendations?
  • Point out the risks regarding putting the hosts in maintenance mode in terms of FSVM.
  • Confirm on all of the requirements and move forward with the physical design.
  • Raise concerns regarding support when running VMs on an NFS share as risk.
  • Highlight the required number of nodes required for the vSAN cluster as a constraint.
Answer: C
8An administrator has received an alert indicating that a single capacity device is close to failing within the production vSAN Cluster. The administrator must now complete preemptive maintenance on the vSAN Cluster without impacting the availability of workloads or vSAN File Services. The following information is known about the vSAN Cluster: ✑ vSAN 7.x Cluster ✑ vSAN node count: 8 ✑ De-Duplication and Compression: Enabled. ✑ Encryption: Disabled Current Utilization: 45% ✑ Disk Groups: 2 ✑ Devices per node: 2 x 400 GB SSD, 6 x 1.8 TB SSD Which three steps should the administrator take to successfully complete the task? (Choose three.)
5V0-21.21 question 8
  • Remove the affected Disk Group from the vSAN Cluster, and choose Full Data Migration.
  • Replace the failed disk with a storage device that is identical in class and capacity.
  • Remove the affected Disk Group from the vSAN Cluster, and choose No Data Migration.
  • Replace the failed disk with a storage device that is identical in class but smaller in capacity.
  • Put the affected vSAN host into maintenance mode to physically replace the storage device.
  • Remove the affected Disk from the Disk Group, and choose Full Data Migration.
Answer:
9A 30-minute power maintenance window has been approved on Sunday. Due to a delay, the maintenance took 20 minutes longer to finish. During this time, the vSAN administrator noticed that one of the clusters nodes was affected by a power shortage, as it was connected to an affected power source. The default vSAN storage policy has been applied. What will be the status of the vSAN objects on the affected host immediately after it is recovered?
  • The cluster will be partitioned and the vSAN host will need to be rejoined.
  • A rebuild of the affected objects will occur.
  • All objects will remain accessible.
  • All objects on the affected host will be lost.
Answer: C
10Due to the success of the recently deployed developer-only private cloud solution, a company has a new requirement to at least double the usable capacity in their all-flash vSAN cluster. The vSAN cluster is deployed into a co-located datacenter that is owned by a third-party hosting company. The hosting company charges a fixed monthly cost for rack space and power consumption. The service owner has been given a limited budget for additional hardware purchases, but not for on-going co-location costs. The current vSAN cluster has the following configuration: ✑ 10 vSAN Nodes with 2 CPUs (20 cores), 512 GB RAM ✑ 1 Disk Group per vSAN node - 1 x 400 GB - 4 x 1.8 TB ✑ De-duplication and Compression is enabled. ✑ vSAN Capacity is currently: - Total: 72 TB - Usable: ~40 TB (FTT1/RAID1) and ~60 TB (FTT1/RAID5). As a result of any action taken, the service owner would like to ensure that overall availability of the vSAN cluster is increased. Which two recommendations meet the requirement to increase capacity while maintaining service availability? (Choose two.)
  • Install an additional 400 GB SSD and 4 x 1.8 TB SSDs per vSAN node.
  • Update the existing Disk Group, and claim the newly installed drives for each node.
  • Create a new Disk Group, and claim the newly installed cache and capacity SSD drives for each node.
  • Install an additional 3 x 1.8 TB SSDs per vSAN node.
  • Replace existing SSDs with an 800 GB SSD and 4 x 3.8 TB SSDs per vSAN node.
