A company has deployed a 12-node (6-6-1) vSAN 7.0 stretched cluster for all production workloads.
The customer currently uses four different vSAN storage policies for running the workloads depending on the applications requirements:

* Policy 2 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Mirroring
* Policy 3 - Site Disaster Tolerance=None - Keep Data on Preferred, FTT=Mirroring

- B. Tag the vmk1 for Witness traffic.
- C. Configure vmk0 with IP address on the same range as that of vmk1.
- D. Tag the vmk0 for vSAN traffic.

If both vmk0 and vmk1 are configured on the same range, a multihoming condition will occur and vSAN traffic will flow from vmk0, rather than vmk1.
NEW QUESTION 38

Answer: C
NEW QUESTION 39
An administrator is tasked with sharing storage from one vSAN cluster to another vSAN cluster. SPBM management must be preserved end-to-end, and the policy must be applied by the source vSAN cluster which is storing the dat a. Both vSAN clusters are managed by the same vCenter server.
What should the administrator configure?
- A. iSCSI targets on vSAN

NEW QUESTION 40
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 network diagnostic mode is not enabled.
- B. vSAN performance service is turned off.
- C. vSAN proactive tests haven't been run yet.
- D. vSAN performance verbose mode is not enabled.
Answer: B
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 41

* 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. Replace the failed disk with a storage device that is identical in class but smaller in capacity.
- 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. Remove the affected Disk Group from the vSAN Cluster, and choose Full Data Migration.
