• Question 1:

  An administrator wants to orchestrate the update of the controller driver and firmware in a vSAN cluster.

  Which is a required step when using VMware vSphere Update Manager and vSAN Health Service to perform the updates?

  B. Install a vendor tool for the controller.

  C. Manually create a vSAN system baseline.

  D. Ensure all controllers are in pass-through mode.

  Correct Answer: C

• Question 2:

  A 4-node vSAN cluster has a single disk group per host. An administrator wants to increase the capacity of the vSAN datastore by adding a second disk group to each host in the cluster. The newer drives intended for the second disk group are certified and in compliance with VMware Compatibility Guide (VCG). However, the newer devices procured are of a different make and model than the existing disk group composition.

  Considering the scenario, which statement is true?

  A. This configuration is supported, however performance may vary across disk groups.

  B. The Capacity Tier devices need to be the same make and model as other disk groups.

  C. The Cache Tier devices need to be the same make and model as other disk groups.

  D. This configuration is supported, however a separate controller is mandatory for each disk vendor.

  Correct Answer: B

• Question 3:

  A customer environment includes:

  4-node vSAN cluster

  5 SQL servers with an OS virtual disk and database virtual disk

  Current policy uses the vSAN Default Storage policy

  A vSAN administrator has created a new policy with fault tolerance method of Erasure Coding with Failures to tolerate equal to 1. The administrator will apply this new policy to the OS disk only.

  Considering this scenario, which two statements are true? (Choose two.)

  A. The policy can't be applied as there are not enough nodes to comply with the policy.

  B. The object tree will have to be rebuilt when the policy is applied.

  C. vSAN policies can only be applied to entire VMs.

  D. This policy will require additional transitional space, until all objects are recreated.

  E. The policy will result in size reduction and only will require 1.5x space instead of 2x.

  Correct Answer: BD

• Question 4:

  Which Kubernetes component must be configured to allow for dynamics provisioning of container volumes on vSAN?

  A. vSphere Container Storage Interface driver

  B. vSphere Cloud Storage Plugin

  C. glusterfs

  D. Cinder

  Correct Answer: A

• Question 5:

  A vSAN disk group contains one cache drive and four capacity drives. A drive that belongs to this disk group has failed. The entire disk group containing the failed drive is offline. What are two possible reasons the entire disk group is offline? (Choose two.)

  A. Deduplication and compression is enabled on the cluster.

  B. RAID-5/6 (Erase Coding) is one of the failure tolerance methods in use.

  C. The failed drive is configured as a cache drive for the disk group.

  D. Data-at-rest encryption is enabled for the disk group.

  E. Two capacity drives in the disk group are offline.

  Correct Answer: CE

• Question 6:

  The Cloud Native Storage control plane in vSphere allows an administrator to provision storage directly from which cloud technology?

  A. Kubernetes Clusters

  B. vRealize Automation

  C. Docker nodes

  D. AWS EC2 instances

  Correct Answer: A

• Question 7:

  An administrator is working with an application which has three characteristics:

  latency sensitive database striped over multiple virtual disks no application redundancy

  Which storage policies meet the VM performance and cluster constraint while protecting against at least 1 failure?

  A. RAID 6, Stripe Width 2

  B. RAID 1, Stripe Width 2

  C. RAID 1, Stripe Width 1

  D. RAID 5, Stripe Width 1

  Correct Answer: D

• Question 8:

  The clomd service has stopped on 1 host in a 3-node vSAN cluster. All other services on the host, as well as the other 2, are healthy. Additionally, the unmodified vSAN Default Storage Policy is in use. Which would be an expected outcome for a new VM deployed into the vSAN cluster?

  A. VM deployment will fail.

  B. VM deployment will complete but VM IO will fail.

  C. VM deployment will complete but performance will be degraded.

  D. VM deployment will be deferred by vCenter.

  Correct Answer: C

• Question 9:

  Which two must be considered when creating a vSAN solution that will utilize VMware vSphere Replication? (Choose two.)

  A. Deduplication and compression must be disabled for PIT snapshots.

  B. Point-in-time snapshots count towards component limit.

  C. vSAN Encryption cannot be used with vSphere Replication.

  D. Additional read I/O will be generated by vSphere Replication.

  E. AES-NI must be enabled prior to using snapshots for replication.

  Correct Answer: CD

• Question 10:

  An administrator has been tasked with the shutdown process of one of the nodes in a 4-node vSAN Cluster, in order to replace a motherboard. The administrator must select the correct maintenance mode option to ensure all objects remain compliant with the vSAN Default Storage Policy. No changes have been made to this policy.

  Which maintenance mode option should the administrator select?

  A. Allow Reduced Redundancy

  B. Ensure Accessibility

  C. Full Data Migration

  D. No Data Migration

  Correct Answer: D
