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?

• Replace all failed disks on the preferred site.
• Replace the vSAN Witness Host
• Replace access to the existing vSAN Witness Host
• Replace only one failed disk on the preferred site.

An administrator is planning to change a vSAN Storage Policy to apply a Failures To Tolerate (FTT) of 2, using RAID-6.What is the minimum number of vSAN nodes required?

• 6
• 4
• 5
• 8

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

• VMware Cloud Foundation
• VMware Horizon
• VMware Tanzu
• VMware vRealize Automation

A customer is planning to migrate their physical Microsoft SQL Server clustered workloads to vSAN enabled vSphere clusters.The following requirements must be met:* Each MSSQL cluster is made up of 3 nodes* Highest possible availability against node failures* Some of the vSAN clusters will only consume storageWhat should the architect recommend?

• vSAN iSCSI Target Service
• Stretched vSAN Cluster
• vSAN Direct
• vSAN File Services

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

• Host-based rules
• vVOL storage rules
• Tag-based placement rules
• Storage performance-based rules

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.)

• Install an additional 400 GB SSD and 4 x 1.8 TB SSDs per vSAN node.
• Update the existing Disk Group, and claim the newly installed drives for each node.
• Create a new Disk Group, and claim the newly installed cache and capacity SSD drives for each node.
• Install an additional 3 x 1.8 TB SSDs per vSAN node.
• Replace existing SSDs with an 800 GB SSD and 4 x 3.8 TB SSDs per vSAN node.

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.)

• The cluster DRS threshold has been set to Aggressive.
• There is a vSAN node failure.
• The vSAN Resync throttling is enabled.
• The object repair timer value has been increased.
• The vSAN policy protection level has changed from FTT=0 to FTT=1.

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

• 100% of the reads comes from vSAN hosts on the local site
• 50% of the reads comes from vSAN hosts on the local site
• 100% of the reads comes from vSAN hosts on the remote site
• 50% of the reads comes from vSAN hosts on the remote site

During a vSAN design workshop, an architect collected these customer requirements:* Leverage vSAN storage policies with Erasure Coding.* Enable Deduplication and Compression.* Use the minimum number of hosts in the cluster.* Maintain full storage policy compliance when two nodes are down.Which vSAN cluster design meets the customer's requirements?

• Five nodes All-Flash vSAN cluster
• Six nodes All-Flash vSAN cluster
• Six nodes Hybrid vSAN cluster
• Five nodes Hybrid vSAN cluster

During a design workshop for a stretched vSAN cluster, the requirement that some of the VMs be configured with no-mirror between sites was discussed.Which three recommendations should the architect provide to address an event of a network partition between two sites? (Choose three.)

• Host isolation response must exclude the VMs required
• The default gateway must be used as the only isolation address
• One of isolation addresses should reside in the site 1 data center
• VMware vSphere DRS rules to force the VMs to run where the data resides
• One isolation address reachable only from the witness appliance in both sites
• One of isolation addresses should reside in the site 2 data center
