NEW QUESTION 16
A company hosts a vSAN 7 stretched cluster for all development workloads. The original sizing of a maximum of 250 concurrent workloads in the vSAN cluster is no longer sufficient and needs to increase to at least 500 concurrent workloads within the next six months.
To meet this demand, the original 8-node (4-4-1) cluster has recently been expanded to 16 nodes (8-8-1).
Which three additional steps should the administrator take to support the current growth plans while minimizing the amount of resources required at the witness site? (Choose three.)
- A. Upgrade the vSAN stretched cluster to vSAN 7.0 U1.
- B. Deploy a new large vSAN witness appliance at the witness site.
- C. Add the new vSAN witness appliance to vCenter Server.
- D. Configure the vSAN stretched cluster to use the new vSAN witness.
- E. Configure the new vSAN witness as a shared witness appliance.
- F. Deploy a new extra large vSAN witness appliance at the witness site.
Answer: B,D,E
NEW QUESTION 17

- B. Disable vSphere Distributed Resources Schedule (DRS) on the vSAN cluster.
- C. Ensure that the vSAN Encryption is enabled by default on the existing cluster to encrypt old and new data.

NEW QUESTION 21
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. Configure vmk1 with IP address on the different network than that of vmk0.
- 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.

NEW QUESTION 23
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 400 GB SSD and 4 x 1.8 TB SSDs per vSAN node.
- B. Update the existing Disk Group, and claim the newly installed drives for each node.
- C. Create a new Disk Group, and claim the newly installed cache and capacity SSD drives for each node.
- D. Replace existing SSDs with an 800 GB SSD and 4 x 3.8 TB SSDs per vSAN node.
- E. Install an additional 3 x 1.8 TB SSDs per vSAN node.
Answer: C,E
NEW QUESTION 24

- B. Enable Data-In-Transit encryption first
- C. Verify if a role with privilege "Cryptographic operations.Migrate" is assigned
- D. Enable that the virtual machines are powered on
- E. Verify if a role with privilege "Cryptographic operations.Encrypt new" is assigned
- F. Create an encryption storage policy
Answer: A,D,E
NEW QUESTION 25
An administrator has an absent capacity disk.
Which action, if any, should the administrator take to resolve the problem?

- D. Replace the faulty disk.
Answer: C
NEW QUESTION 26
An architect collected the below technical requirements from the customer during a vSAN cluster design workshop:
* Maximize the vSAN datastore usable capacity.
* Deduplication and compression are required to help utilize available capacity efficiency.
* Ensure the highest level of resiliency wherever possible.
Which disk group configuration should the architect include in the design?
- A. One disk group per host, with one cache tier flash disk and four capacity tier flash disks.
- B. Two disk groups per host, each with one cache tier flash disk and four capacity tier flash disks.
- C. Two disk groups per host, each with one cache tier flash disk and six capacity tier flash disks.
- D. Two disk groups per host, each with one cache tier flash disk and six capacity tier magnetic disks.
Answer: D
NEW QUESTION 27
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 28
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
- B. HCI Mesh on vSAN
- C. vVOLs on vSAN
- D. NFS volumes on vSAN
Answer: B
NEW QUESTION 29
