NEW QUESTION 30
cluster for a customer who is planning to use vRealize Automation to provision 600 virtual machines into that cluster, with expected growth up to 1,000 VM. Each VM has a 40GB thick-provisioned disk.
Which flash disk size is required for the cache tier per ESXi node to meet all requirements?
- A. 800GB
- B. 400GB
- C. 600GB
- D. 700GB
Answer: A
Explanation:
40GB x 1000VMs = 40 000 GB total max expected usage 40 000GB / 5 node cluster = 8000 GB per node cache should be 10% so 800GB SSD is needed. However this question is stupid from real life perspective. one host can run up to 200 VMs - so what with MM, any failure ? Cluster should be sized with 6 ESXi hosts minumim
NEW QUESTION 31
Which statement accurately describes the result when proper VM Storage Policy Affinity Rules on a stretched vSAN cluster are set?
- A. When a site is disconnected, the VM will continue to have access to its VMDK.
- B. Proper policies result in higher inter-site bandwidth utilization.
- C. Bandwidth is unnecessarily sent across the inter-site link.
- D. When a site is disconnected, the VM will lose access to its VMDK.
Answer: D
NEW QUESTION 32
After a vSAN Witness Appliance network configuration, the vSAN administrator notices that vSAN traffic flows from vmk0 (Management Traffic) rather than vmk1 (vSAN Traffic).
Which step should be taken to resolve this issue?
- A. Tag the vmk0 for vSAN traffic.
- B. Configure vmk1 with IP address on the different network than that of vmk0.
- C. Tag the vmk1 for Witness traffic.
- D. Configure vmk0 with IP address on the same range as that of vmk1.
Answer: D
Explanation:
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 33
An organization has two vSAN clusters managed by the same vCenter Server, each providing 100TB of storage. The first cluster runs at 75% of its storage capacity, and the second cluster runs at 50% of its storage capacity.

Which requirement is specifically needed for these devices?
- A. Read endurance
- B. IOPS
- C. Write endurance
- D. Capacity
Answer: C
Explanation:
Reference:
In all-flash configurations, vSAN uses the cache layer for write caching only. The write cache must be able to handle high write activities. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan-planning.doc/GUID-1D6AD25A-459A-43D6-8FF5-52475499D6A2.html

- A. vVOLs on vSAN
- B. iSCSI targets on vSAN
- C. HCI Mesh on vSAN
- D. NFS volumes on vSAN

NEW QUESTION 41
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 44
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 1 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Erasure Coding
* Policy 2 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Mirroring
* Policy 3 - Site Disaster Tolerance=None - Keep Data on Preferred, FTT=Mirroring
* Policy 4 - Site Disaster Tolerance=None - Keep Data on Non-Preferred, FTT=Mirroring During the setup of the vSAN stretched cluster, the following VM/Host Rules were created:
* Preferred Site - Preferred Site workloads should run on DC1 hosts.
* Secondary Site - Secondary Site workloads should run on DC2 hosts.
Which two activities should the administrator complete to ensure that there is no impact to production services during the maintenance window in the Preferred Site? (Choose two.)
- A. Update vSphere DRS site affinity rules so that Preferred Site workloads should not run on hosts in DC1.
- B. Change the Site Disaster Tolerance setting in Policy 4 to be "None - Keep Data on Preferred".
- C. Change the FTT setting in Policy 3 to be "Erasure Coding".
- D. Update vSphere DRS site affinity rules so that Preferred Site workloads must run on hosts in DC2.
- E. Change the Site Disaster Tolerance setting in Policy 3 to be "Dual Site Mirroring".
Answer: D,E
NEW QUESTION 45
In a vSAN stretched cluster, which value must be set in the vSAN policy if there is no requirement for data mirroring across sites?
- A. PFTT = 1
- B. PFTT = 0
- C. SFTT = 1
- D. SFTT = 0
Answer: B
Explanation:
PFTT can be seen as "site failures", and you can always only tolerate 1 at most. SFTT can be seen as host failures, and you can define this between 0 and 3 https://www.yellow-bricks.com/2018/03/19/vsan-stretched-cluster-pftt-and-sftt-what-happens-when-a-full-site-fails-and-multiple-hosts-fail/
