NEW QUESTION # 67
An administrator is tasked with preparing for a Cross vCenter migration in a stretched vSAN cluster where the virtual machines migration will be orchestrated via VMware Site Recovery Manager.
Which action should the administrator take so the migration is successful?
- A. Make sure that Witness traffic is on the management NIC.

NEW QUESTION # 68
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 proactive tests haven't been run yet.
- C. vSAN performance service is turned off.
- D. vSAN performance verbose mode is not enabled.
Answer: C
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 # 69
An architect is working with an All-Flash vSAN configuration and will be using the Flash Caching Devices in vSAN.
Which requirement is specifically needed for these devices?
- A. IOPS
- B. Write endurance
- C. Capacity
- D. Read endurance
Answer: B
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
NEW QUESTION # 70

- A. vSAN iSCSI
- B. vSAN File services
- C. VMware vSAN Direct
- D. vSAN Compression Only
Answer: C
NEW QUESTION # 71

NEW QUESTION # 72
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 data. Both vSAN clusters are managed by the same vCenter server.
What should the administrator configure?
- A. HCI Mesh on vSAN
- B. vVOLs on vSAN
- C. iSCSI targets on vSAN
- D. NFS volumes on vSAN
Answer: A
Explanation:
HCI Mesh is a unique, software-based approach for disaggregation of compute and storage resources. HCI Mesh brings together multiple independent vSAN clusters for a native, cross- cluster architecture that disaggregates resources and enables utilization of stranded capacity.
Simply, vSAN allows one or more vSAN clusters to remotely mount datastores from other vSAN clusters (servers) within vCenter inventory. This approach maintains the essence and simplicity of HCI by not fundamentally changing the existing HCI model or requiring specialized hardware.
Now, a cluster with excess compute can mount excess storage from a remote vSAN cluster.
NEW QUESTION # 73
An administrator is tasked with setting up HCI mesh between the following two vSAN clusters:
- Cluster 1 uses FTT=1 via mirroring
- Cluster 2 uses FTT=1 via Erasure Coding
The administrator configures Cluster 2 as the cluster that is contributing storage to HCI mesh.
Which FTT applies to objects created on Cluster 1 when using the HCI Mesh shared storage?
- A. HCI mesh always uses FTT = 0.
- B. HCI Mesh always uses the source vSAN cluster to set its policy.
- C. HCI Mesh always uses the default vSAN policy from the target site.
- D. HCI mesh always uses FTT = 1.
Answer: C

NEW QUESTION # 75
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. Tag the vmk1 for Witness traffic.
- C. Configure vmk0 with IP address on the same range as that of vmk1.
- D. Configure vmk1 with IP address on the different network than that of vmk0.
Answer: C
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 # 76
An architect is designing a vSAN cluster where the hosts have more than 512 GB of memory.
Which two boot devices are recommended for these hosts? (Choose two.)
- A. SATADOM
- B. Disk Device
- C. PMEM
- D. USB
- E. SD
Answer: A,B
NEW QUESTION # 77
Due to the success of the recently deployed developer-only private cloud solution, a company has a new requirement to at least double the usable capacity in their all-flash vSAN cluster.
The vSAN cluster is deployed into a co-located datacenter that is owned by a third-party hosting company. The hosting company charges a fixed monthly cost for rack space and power consumption. The service owner has been given a limited budget for additional hardware purchases, but not for on-going co-location costs.
The current vSAN cluster has the following configuration:
* 10 vSAN Nodes with 2 CPUs (20 cores), 512 GB RAM
* 1 Disk Group per vSAN node
- 1 x 400 GB
- 4 x 1.8 TB
* De-duplication and Compression is enabled.
* vSAN Capacity is currently:
- Total: 72 TB
- Usable: ~40 TB (FTT1/RAID1) and ~60 TB (FTT1/RAID5).
As a result of any action taken, the service owner would like to ensure that overall availability of the vSAN cluster is increased.
Which two recommendations meet the requirement to increase capacity while maintaining service availability? (Choose two.)
- A. Install an additional 3 x 1.8 TB SSDs per vSAN node.
- B. Update the existing Disk Group, and claim the newly installed drives for each node.
- C. Replace existing SSDs with an 800 GB SSD and 4 x 3.8 TB SSDs per vSAN node.
- D. Create a new Disk Group, and claim the newly installed cache and capacity SSD drives for each node.
- E. Install an additional 400 GB SSD and 4 x 1.8 TB SSDs per vSAN node.
Answer: A,D
NEW QUESTION # 78
An architect is designing a vSAN cluster.
Which storage controller option will yield optimal performance?
- A. Hugh queue depth
- B. Set caching to 50% read on the controller
- C. Enable battery write-back caching
- D. RAID 0
Answer: A
Explanation:
Storage Controller Queue Depth
There are two important items displayed by the VCG for storage I/O controllers that should be noted. The first of these is "features" and the second is queue depth.
Queue depth is extremely important, as issues have been observed with controllers that have very small queue depths. In particular, controllers with small queue depths (less than 256) can impact virtual machine I/O performance when vSAN is rebuilding components, either due to a failure or when requested to do so when entering maintenance mode.
Design Decision : Choose storage I/O controllers that have as large a queue depth as possible.
While 256 are the minimum, the recommendation would be to choose a controller with a much larger queue depth where possible.

- B. Restore the communication with the KMS server, and re-establish the trust relationship.
- C. Replace the caching device in each affected disk group.
- D. Run /etc/init.d/vsanvpd restart to rescan the VASA providers.
