Question1: 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?

Question2: 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?

Question3: A 4-node vSAN cluster is configured with an erasure coding storage policy. The Ensure Accessibility maintenance mode was selected. While performing the maintenance, a second node fails.
What will be the impact on the vSAN cluster?

Question4: data centers, the customer relayed the following information:
* Highest possible mitigation during a host failure in terms of capacity.
* A constraint in this year's IT budget.
What should the architect recommend?

Question5: An architect is tasked to design a VMware Horizon Solution with vSAN. The architect needs to use a solution to host the user's profile shares in a highly available manner, and it must be guest OS independent.
Which solution will match these requirements?

Question6: An administrator is planning to deploy cloud-native workloads onto the vSAN Direct datastore.
Which storage policy structure rule is supported?

Question7: An architect needs to automate an infrastructure that supports VMware Horizon as well as VMware Tanzu.
Which solution mandates the use of VMware vSAN?

Question8: 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?

Question9: Which statement accurately describes the result when proper VM Storage Policy Affinity Rules on a stretched vSAN cluster are set?

Question10: An administrator is tasked with setting up Kerberos authentication only for the vSAN File services.
Which version of Kerberos must be selected if the NFS version is v4.1?

Question11: A company has deployed a 12-node (6-6-1) vSAN 7.0 stretched cluster for all production workloads.
The customer currently uses four different vSAN storage policies for running the workloads depending on the applications requirements:
* Policy 1 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Erasure Coding
* Policy 2 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Mirroring
* Policy 3 - Site Disaster Tolerance=None - Keep Data on Preferred, FTT=Mirroring
* Policy 4 - Site Disaster Tolerance=None - Keep Data on Non-Preferred, FTT=Mirroring During the setup of the vSAN stretched cluster, the following VM/Host Rules were created:
* Preferred Site - Preferred Site workloads should run on DC1 hosts.
* Secondary Site - Secondary Site workloads should run on DC2 hosts.
Which two activities should the administrator complete to ensure that there is no impact to production services during the maintenance window in the Preferred Site? (Choose two.)

Question12: cluster for a customer who is planning to use vRealize Automation to provision 600 virtual machines into that cluster, with expected growth up to 1,000 VM. Each VM has a 40GB thick-provisioned disk.
Which flash disk size is required for the cache tier per ESXi node to meet all requirements?

Question13: 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?

Question14: In a stretched vSAN cluster, how is Read Locality established after fail over to the secondary site?

Question15: An administrator is tasked to create a custom storage policy for workloads and is including additional disk stripes while defining the storage policy.
What is the main purpose of this practice?

Question16: An administrator is planning to deploy cloud-native workloads onto the vSAN Direct datastore.
Which storage policy structure rule is supported?

Question17: In a vSAN stretched cluster, which value must be set in the vSAN policy if there is no requirement for data mirroring across sites?

Question18: 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?

Question19: 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?

Question20: 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?

Question21: A cache disk failure marked a vSAN disk group as failed, and the data is being rebuilt on other disk groups.
Which action should the vSAN administrator take to reduce the negative impact on the VMs?

Question22: Upon investigating a workload performance issue, a vSAN administrator observed a high backend IOPs on a vSAN cluster.
Which two causes explain this behavior? (Choose two.)

Question23: A 30-minute power maintenance window has been approved on Sunday. Due to a delay, the maintenance took 20 minutes longer to finish.
During this time, the vSAN administrator noticed that one of the clusters nodes was affected by a power shortage, as it was connected to an affected power source. The default vSAN storage policy has been applied.
What will be the status of the vSAN objects on the affected host immediately after it is recovered?

Question24: An administrator is tasked with setting up Kerberos authentication only for the vSAN File services.
Which version of Kerberos must be selected if the NFS version is v4.1?

Question25: During a maintenance action on a vSAN node, a vSAN administrator noticed that the default repair delay time is about to be reached.
Which two commands must be run to extend the time? (Choose two.)
