Question1: An administrator has an absent capacity disk.
Which action, if any, should the administrator take to resolve the problem?

Question2: An administrator is troubleshooting vSAN performance issues, and the performance diagnostics reports:
"There are errors seen in one or more physical NICs on one or more hosts." Which two problems must be resolved to fix this issue? (Choose two.)

Question3: An organization has two vSAN clusters managed by the same vCenter server, each providing 100 TB of storage. The first cluster runs at 75% of its storage capacity, and the second cluster runs at 40% of its storage capacity.
The company also has the following:

Question15: An administrator is planning to deploy workloads on a six node vSAN cluster, and all nodes are distributed equally across three racks.
Which action is required to ensure that the workload VMs remain compliant with the default vSAN policy after a complete rack failure?

Question16: 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?

Question17: An administrator is setting up vSAN file services on a vSAN cluster.
Which two security policies on the distributed port groups are automatically enabled in the process? (Choose two.)

Question18: An administrator has been tasked to reboot a node in an encrypted vSAN cluster. The vSAN disk groups on that node become locked after rebooting the node.
Which step should be performed to exit the locked state?

Question19: 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?

Question20: An architect intends to use the Primary Level of Failures To Tolerate (PFTT) to calculate the minimum number of required hosts for a vSAN cluster.
Which calculation model should be used?

Question21: 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.)

Question22: An administrator is setting up vSAN file services on a vSAN cluster.
Which two security policies on the distributed port groups are automatically enabled in the process? (Choose two.)

Question23: An administrator has noticed that a number of the virtual machines in the preferred site are showing as either failed or partitioned.
In which two ways would the administrator expect the virtual machines to respond? (Choose two.)

Question24: During a vSAN design workshop, a customer expressed a requirement to decommission an existing enterprise NAS device that provides iSCSI services for a clustered application.
Based on the current state analysis, the following information was noted:
- Current utilization is 500 LUNs.
- All clustered workloads are configured for Multiple Connections per Session.
- LUN sizes range between 10 TB to 30 TB.
What should the architect state regarding the requirements?

Question25: An administrator wants to enable encryption on an existing vSAN cluster that already contains virtual machines.
Which additional step should the administrator take to ensure no data is lost during the encryption process?

Question26: 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?

Question27: An administrator of "vsan-prod" cluster noticed the witness components of VMs are flagged as absent after a failed attempt to replace the vSAN Witness Host.
Which action should the administrator take to resolve this issue?

Question28: 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.)

Question29: 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?
