質問 1：
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. Install an additional 3 x 1.8 TB SSDs per vSAN node.
D. Replace existing SSDs with an 800 GB SSD and 4 x 3.8 TB SSDs per vSAN node.
E. Create a new Disk Group, and claim the newly installed cache and capacity SSD drives for each node.
正解：A,E

質問 2：
As a part of a network hardware refresh project, all the network switches have been replaced with a newer, high-performance model. After the replacement, the company users started experiencing slowness on the applications hosted on their vSAN-backed VMs.
The vSAN administrator checked the vSAN Network Health status and noticed that the "Hosts large ping test" has failed.
What could be the cause of this performance degradation issue?
A. MTU 9K is not configured on the vDS switch.
B. MTU 9K is not configured on the hosts VMnic ports.
C. MTU 9K is not configured on the ToR switch.
D. MTU 9K is not configured on the hosts vSAN vMKernel ports.

質問 3：
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 lose access to its VMDK.
B. Proper policies result in higher inter-site bandwidth utilization.
C. When a site is disconnected, the VM will continue to have access to its VMDK.
D. Bandwidth is unnecessarily sent across the inter-site link.

質問 5：
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.
Which two root causes can be identified to help remediate the issue? (Choose two.)
A. vSAN VMKemel portgroup is configured with the "Route based on IP hash" teaming policy
B. Large packet losses and retransmissions on the network layer
C. One or more disk groups are congested
D. vSAN encryption is enabled
E. Incorrect sizing of the disk groups capacity disks
正解：B,C

質問 6：
An 8-Node vSAN Stretched Cluster (4+4+1) with a single disk group has a policy with PFTT=1 (mirrored across sites) and SFTT=1/FTM Mirroring (Local Protection) configured.
The administrator has been alerted that there is a problem with the cluster. The following has been observed:
* The vSAN Witness Host is offline.
* Two disk failures on two hosts have occurred in the preferred site.
This has resulted in a critical production virtual machine's vmdk becoming inaccessible.
Which step needs to be performed by the administrator to resolve the issue?
A. Replace access to the existing vSAN Witness Host
B. Replace only one failed disk on the preferred site.
C. Replace the vSAN Witness Host
D. Replace all failed disks on the preferred site.
正解：A

質問 7：
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.
Which storage option will work for this use case?
A. Obtain additional free capacity from the existing NAS storage.
B. Obtain additional free capacity from the existing FC storage.
C. Create an HCI Mesh using the first cluster's datastore.
D. Create an HCI Mesh using the second cluster's datastore.
正解：D
