NEW QUESTION 29
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.
The company also has the following:
* An iSCSI array of 300TB. which runs at 76% of its capacity
* A NAS system of 200TB, which runs at 10% of its capacity
* A Fiber channel (FC) array of 300TB, which runs at 80% of its capacity The administrator is asked to add an additional 25TB of storage to the first cluster. The administrator is also made aware that there is no budget to purchase new hardware and that the vSAN Storage Policy Based Management must be kept in place.

NEW QUESTION 32
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. Deploy a new extra large vSAN witness appliance at the witness site.
- B. Add the new vSAN witness appliance to vCenter Server.
- C. Configure the new vSAN witness as a shared witness appliance.

- F. Configure the vSAN stretched cluster to use the new vSAN witness.
Answer: C,E,F
NEW QUESTION 33
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 verbose mode is not enabled.
- C. vSAN proactive tests haven't been run yet.
- 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 34
An administrator managing a vSAN cluster of six-nodes with policy FTT-2/RAID-6 decided to put one of the nodes in maintenance mode using the "Full-data migration" option.
What will happen after this action is taken?
- A. The system will prompt to add an additional host to the cluster in order to preserve the policy compliance.
- B. The host will enter in maintenance mode and only data with no redundancy will remain accessible.
- C. The host will enter into maintenance mode if both components of a certain object are residing on that host, then one of the components will be moved to another available host.
- D. The host will enter in maintenance mode and the data will remain accessible until the host exits maintenance mode.
Answer: D
NEW QUESTION 35
Upon checking the latency goal under vSAN performance diagnostics, the vSAN Administrator sees this message displayed:
The increase in latency in the vSAN stack might be beyond expected limits.

- A. vSAN encryption is enabled
- B. vSAN VMKemel portgroup is configured with the "Route based on IP hash" teaming policy
- C. Incorrect sizing of the disk groups capacity disks
- D. Large packet losses and retransmissions on the network layer
- E. One or more disk groups are congested
Answer: D,E
NEW QUESTION 36

NEW QUESTION 40
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. Create a new Disk Group, and claim the newly installed cache and capacity SSD drives for each node.
- B. Install an additional 400 GB SSD and 4 x 1.8 TB SSDs per vSAN node.
- C. Update the existing Disk Group, and claim the newly installed 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: A,E

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 = 0
- D. SFTT = 1
Answer: B
