VMware VMware Certifications 2VB-601 Questions & Answers

• Question 41:

  How does vSAN respond when a vSAN drive is pulled from a server chassis or a host if a vSAN cluster fails without warning?

  A. Components on the affected device(s) are marked as absent. vSAN will attempt to rebuild the components after the VSAN.ClomRepairDelay timer, which is set to 60 minutes by default, expires.

  B. Components on the affected device(s) are marked as inaccessible. vSAN will attempt to rebuild the components the next time a host enters maintenance mode.

  C. Components on the affected device(s) are marked as degraded. vSAN will attempt to rebuild the components the next time a host enters maintenance mode.

  D. Components on the affected device(s) are marked as healthy. vSAN will attempt to rebuild the components after the VSAN.ComponentRecovery timer, which is set to 60 minutes by default, expires.

  E. Components on the affected device(s) are marked as stale. vSAN will attempt to rebuild the components after the VSAN.ComponentRecovery timer, which is set to 90 minutes by default, expires.

  Correct Answer: A

• Question 42:

  Which VMware-recommended tool is used to size vSAN deployments?

  A. ReadyNode Configuration

  B. vSAN TCO and Sizing Calculator

  C. vSAN Hardware Compatibility List

  D. Sizing spreadsheets available from partners

  Correct Answer: B

• Question 43:

  What must be enabled for the vSAN online health feature to function?

  A. Proactive Tests Service

  B. vRealize Operatons vSAN Status Plugin

  C. Customer Experience Improvement Program

  D. vSphere Proactive HA

  Correct Answer: C

• Question 44:

  An administrator is designing a new vSphere cluster with vSAN enabled that will span four racks with multiple hosts per rack. The requirement is to provide recoverability during a rack outage.

  What needs to be done to meet this requirement?

  A. Configure Site Recovery Manager.

  B. Nothing, vSAN will automatically recover.

  C. Configure vSphere Replication.

  D. Configure fault domains.

  Correct Answer: D

• Question 45:

  What is the purpose of the cache tier in an all-flash vSAN configuration?

  A. The cache tier is used only for write buffering.

  B. The cache tier is used only for read cache.

  C. 70% of the cache tier is used for read cache and 30% is used for write buffering.

  D. 50% of the cache tier is used for read cache and 50% is used for write buffering.

  Correct Answer: A

  Explanation: all-flash vSAN configurations continue to use the cache tier as a write buffer References: https://www.vsan-essentials.com/chapter-5-architectural-details

• Question 46:

  Which statement is true about two-node vSAN cluster configuration?

  A. Two-node configurations do not require a witness host appliance.

  B. Only the 'Ensure data accessibility' option can be used when entering maintenance mode.

  C. Two witness host appliances can be simultaneously used for redundancy.

  D. When a host fails, vSAN rebuilds data on the other host to protect against another failure.

  Correct Answer: B

• Question 47:

  Which storage policy is automatically created by Horizon View?

  A. Level of failures to tolerate

  B. Checksum

  C. Horizon Default Storage Policy

  D. Linked Clone

  Correct Answer: D

• Question 48:

  Which three of the listed statements are true about vSAN deduplication and compression? (Choose three.)

  A. Deduplication and compression can help to provide additional host failure tolerance.

  B. Deduplication and compression require at least four hosts.

  C. Deduplication and compression reduce redundant data within each disk group.

  D. Deduplication and compression results vary based on the types of data stored in a vSAN environment.

  Correct Answer: ACD

• Question 49:

  When can a change to a storage policy be made?

  A. Only when creating a new policy, because policies become protected objects after creation.

  B. A change to SPBM policies can be made at any time.

  C. A change to a policy can be made at any time, but only if there are no VMs using that policy.

  D. After shutting down any VMs using that policy to ensure data integrity.

• Question 50:

  A 16-node vSAN cluster has been deployed in a primary data center. All virtual machines are assigned a storage policy containing the rule Primary level of failures to tolerate = 1. A storage controller in one of the nodes produces several errors and eventually suffers a permanent failure.

  How does vSAN handle this issue?

  A. All components on the drives attached to the failed storage controller are marked "Stale". An administrator must log into the vSphere Web Client and click the Repair Objects Immediately button to

  restore redundancy.

  B. All components on the drives attached to the failed storage controller are marked "Stale". vSAN starts rebuilding the affected components on other healthy drives in the vSAN cluster after 60 minutes have elapsed.

  C. All components on the drives attached to the failed storage controller are marked "Absent". vSAN starts rebuilding the affected components on other healthy drives in the vSAN cluster after the affected host is put into maintenance node.

  D. All components on the drives attached to the failed storage controller are marked "Degraded". vSAN immediately starts rebuilding the affected components on other healthy drives in the vSAN cluster.

  Correct Answer: D
