New vSAN Specialist 2020 Exam 5V0-21.19 Dumps Questions

1. Which two vSAN Health Check items are included for vSphere Update Manager integration? (Choose two.)

2. What is a benefit of using vSphere Distributed Switches in a vSAN network?

3. A single disk in a vSAN disk group suffers from an unrecoverable hardware failure. This causes vSAN to set the health status for all disks in the group to Permanent disk loss, indicating disk failure.

Assuming all other disks have not suffered from a hardware failure, why would vSAN mark all disks in the group as failed?

4. In stretched clusters, what is a benefit of implementing a virtual witness rather than a physical witness?

5. A storage administrator discovers vSAN is rebalancing components across a cluster randomly and faces degraded performance on the applications.

What should be done to avoid these issues?

6. What is the purpose of slack space in vSAN?

7. The objects on a 4-node vSAN cluster are assigned a RAID-5 policy. A network outage occurs causing host one to lose connectivity with the rest of the cluster. Seventy-five minutes elapse.

What is the health state of the objects?

8. A vSAN 5-node cluster has two sets of VMs, each associated with a separate storage policy. -Group A (Storage Policy: FTT=0) -Group B (Storage Policy: FTT=2)

What are two possible results when two hosts in the vSAN cluster fail permanently? (Choose two.)

9. A 3-node vSAN cluster will take which two actions, when a drive is physically removed from a vSAN node? (Choose two.)

10. A vSAN cluster has this configuration:

– 4 hosts with 1 disk group per host

– Each disk group contains 1 cache device and 7 capacity devices

What are two ways to increase the vSAN datastore storage capacity? (Choose two.)

11. An organization is no longer compliant with security requirements because a vSphere administrator disabled encryption on a vSAN cluster.

Which vCenter Server role ensures only authorized vSphere administrators have access to encryption functionality?

12. vCenter Server is offline.

What are two ways to check the health of a vSAN cluster? (Choose two.)

13. What are two purposes of a vSAN storage policy? (Choose two.)

14. An administrator wishes to prevent notifications of vSAN Health status during a scheduled maintenance window.

What can be done to achieve this?

15. An administrator is planning to deploy a new vSAN cluster with these requirements:

– Physical adapters will share capacity among several traffic types

– Guaranteed bandwidth for vSAN during bandwidth contention

– Enhanced security and performance

What must be considered when configuring the new vSAN cluster?

16. Which two conditions should be verified before removing the ESXi host from a vSAN cluster? (Choose two.)

17. Which VM file type resides in the VM home namespace object on a vSAN datastore?

18. In a 10-node hybrid vSAN cluster, each node has seven 4TB magnetic disks and one 2TB SSD.

What is the raw storage capacity of the vSAN datastore?

19. Refer to the exhibit.

A solution architect is setting up a highly resilient vSAN hybrid cluster.

Why is the cache incorrectly sized in this configuration?

20. An all-flash vSAN cluster contains four nodes.

Which two storage policies can the cluster satisfy? (Choose two.)

21. A company implements a vSAN environment with linked clone virtual desktops and homogeneous desktop operating systems. During the last three months, users have experienced intermittent high latency, degraded performance, and lockout from desktops.

Which two methods should an administrator use to monitor and respond to the issues? (Choose two.)

22. An administrator has discovered that space utilized by VMs does not decrease after deleting files and folders within the VMs. The administrator needs to be able to reclaim this space.

Which action could the administrator perform to accomplish this task?

23. End-users are complaining that an application running on an all-flash vSAN datastore is not performing well.

Which performance chart should an administrator view to troubleshoot this issue?

24. Which two features are available with the Cluster Quickstart wizard? (Choose two.)

25. A system administrator running a 6-node cluster is trying to enable the deduplication and compression feature. During the process of switching it on, the General vSAN error occurs.

What is the possible reason the General vSAN error occurred?

26. The vSAN host memory needs to be replaced and the entire operation is expected to take 90-120 minutes.

Which vSAN advanced setting can be adjusted to avoid rebuild operations during the host hardware maintenance?

27. You are designing a vSAN stretched cluster solution.

What is the maximum number of nodes possible for this solution?

28. What are two recommended reasons for configuring a cluster with at least one node in addition to the minimum required number? (Choose two.)

29. vCenter reports a number of vSAN network alarms on a 2-node vSAN Direct Connect cluster. The test pings show irregularities in the ping results.

Using vSAN Health service, which two checks should be used to identify the network root cause? (Choose two.)

30. A vSAN administrator is designing a new all-flash vSAN cluster. The cluster will host read intensive applications.

Which factor should be included in the design to improve read performance?

31. Which storage policy action results in a component resync?

32. vSAN is configured with a storage policy with a Failures To Tolerate (FTT) set to three.

Which type of redundancy is being used?

33. Which default VMware vSphere High Availability cluster setting must be changed when using a vSAN stretched cluster?

34. The cluster level backend IOPS performance graph shows a higher-than-average number of IOPS.

What is a possible reason for this?

35. An administrator of a vSAN 6.5 environment is planning a path to move to unicast for the vSAN network.

How will the administrator achieve this?

36. When using vSAN Encryption, where does the Key Encryption Key persistently reside?

37. What is a mandatory requirement for a vSAN stretched cluster?

38. An architect is asked to design a vSAN cluster with these requirements:

– Supports erasure coding storage policy

– Minimized inaccessibility from single device failures

– Ability to re-protect data after a failure

The desired configuration should be able to survive a single failure.

Which configuration satisfies the design requirements?
