NEW QUESTION 34
An 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.)
- A. Put the affected vSAN host into maintenance mode to physically replace the storage device.
- B. Replace the failed disk with a storage device that is identical in class and capacity.
- C. Remove the affected Disk from the Disk Group, and choose Full Data Migration.
- D. Replace the failed disk with a storage device that is identical in class but smaller in capacity.
- E. Remove the affected Disk Group from the vSAN Cluster, and choose Full Data Migration.
- F. Remove the affected Disk Group from the vSAN Cluster, and choose No Data Migration.
Answer: A,B,C
Explanation:
If you upgrade the capacity device, verify the following requirements:
- Verify that the cluster contains enough space to migrate the data from the capacity device.
- Place the host in maintenance mode. See Place a Member of Virtual SAN Cluster in Maintenance Mode.
"Select the flash capacity device or magnetic disk, and click Remove selected disk(s) from disk group."

NEW QUESTION 35
Upon investigating a workload performance issue, a vSAN administrator observed a high backend IOPs on a vSAN cluster.
Which two causes explain this behavior? (Choose two.)
- A. The vSAN Resync throttling is enabled.
- B. The vSAN policy protection level has changed from FTT=0 to FTT=1.
- C. The cluster DRS threshold has been set to Aggressive.
- D. The object repair timer value has been increased.
- E. There is a vSAN node failure.
Answer: A,B
NEW QUESTION 36
An administrator wants to check the performance metrics for the workloads and their virtual disks that are running on a vSAN cluster, but no statistical charts are displayed in the vSphere client.
Why is this behavior being seen?
- A. vSAN proactive tests haven't been run yet.
- B. vSAN network diagnostic mode is not enabled.
- C. vSAN performance verbose mode is not enabled.
- D. vSAN performance service is turned off.
Answer: D
Explanation:
Some tools allow for measuring latency peaks. This unfortunately isn't ideal, as it can unfairly represent statistical outliers, which may very well occur when there is little to no I/O activity. The best way to understand the actual behavior of VM and application latencies is to observe in time based performance graphs. Depending on the level of detail, you may need to measure at the individual VMDK level. Become familiar with these graphs to determine what is normal, and what is not for that given application. This is where you can use built-in functionality of vCenter and the vSAN performance service metrics to gather this information.
NEW QUESTION 37

- C. Cluster out of the box
- D. NFS on vSAN
Answer: B
