• Question 31:

  The following are configuration details for a three-node vSAN cluster:

  1.

  Each host has two disk groups and each disk group has 7x1.2TB 10K SAS drives.

  2.

  Each host has 16.8TB of raw capacity and the three-node cluster has 50.4TB of raw capacity.

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: A

• Question 32:

  The following are configuration details for a 10-node hybrid vSAN cluster:

  Each node has 7 x 2 TB magnetic disks, 1 x 800 GB SSD.

  What is the raw capacity of this cluster as configured?

  A. 148TB

  B. Not enough information provided. Cannot be calculated.

  C. 140TB

  D. Cannot be calculated until vSAN is online.

  Correct Answer: A

• Question 33:

  vSAN supports Microsoft Windows Server Failover Cluster (WSFC) with which configuration?

  A. File share witness quorum with Exchange Database Availability Groups, SQL Server AlwaysON Availability Groups (AAG)

  B. Virtual raw device mapping (RDM) with Exchange Database Availability Groups, SQL Server AlwaysOn Availability Groups (AAG)

  C. FCI witness quorum with Exchange Database Availability Groups, SQL Server AlwaysOn Availability Groups (AAG)

  D. NFS mount witness quorum with Exchange Database Availability Groups, SQL Server AlwaysON Availability Groups (AAG)

  Correct Answer: C

• Question 34:

  What is the Storage-Based Management framework primarily used for?

  A. Providing a single unified control plane across a broad range of data services and storage solutions

  B. Defining target deduplication and compression ratios and distributing workloads to optimize space efficiency based on the defined targets

  C. Ensuring an appropriate RPO is assigned and monitored using either synchronous or asynchronous replication of a datastore

  D. Reducing the latency on datastores by distributing IO across physical devices by abstraction and pooling of resources

  Correct Answer: A

• Question 35:

  A. Network

  B. Physical Disk

  C. Device Mapping

  E. Replication

  Correct Answer: ABD

• Question 36:

  When using RAID-5 with a 100GB virtual disk, what is the maximum capacity consumed on the vSAN datastore for this virtual disk?

  A. 100GB

  B. 150GB

  C. 133GB

  D. 200GB

  Correct Answer: B

• Question 37:

  An eight-node vSAN cluster has been deployed. vSAN fault domains are NOT configured. A virtual machine with a 100GB virtual disk (VMDK) is created on the cluster. The 100GB virtual disk is assigned a storage policy with the following rules:

  1.

  Primary level of failures to tolerate = 1

  2.

  Failure tolerance method = RAID-1 (Mirroring) ?Performance

  Which statement is true about how vSAN places the component(s) that make up this object?

  A. Three mirrored data components are created and distributed across separate hosts. There is NO need for a witness component.

  B. Three mirrored data components plus a witness component are created. The data components are distributed across three hosts in the cluster. Witness components are placed on the hosts that contain data components to verify the data components are online.

  C. One data component is created to minimize capacity consumption. Two witness components are placed on separate hosts to avoid "split-brain" scenarios.

  D. Two mirrored data components plus a witness component are created. The components are distributed across three nodes in the cluster.

  Correct Answer: B

• Question 38:

  Which two VM Storage Policy rules are supported with vSAN iSCSI Target LUNs? (Choose two.)

  A. Replication

  B. RAID-5/6 erasure coding - Capacity

  C. Deduplication and Compression

  D. Force Provisioning

  Correct Answer: BC

• Question 39:

  Which statement is true about the deduplication and compression feature in vSAN?

  A. Redundant blocks across multiple disk groups are NOT deduplicated.

  B. Compression removes redundant data blocks, whereas deduplication removes additional redundant data within each data block.

  C. Compression occurs as data is moved from the capacity tier to the cache tier.

  D. Deduplication and compression are enabled by default when the vSAN cluster is created.

  Correct Answer: A

• Question 40:

  What is the purpose of the cache tier in an all-flash vSAN cluster?

  A. Read caching only.

  B. 30% write caching and 70% read caching.

  C. 20% write caching and 70% read caching and 10% checksum metadata.

  D. Write caching only.

  Correct Answer: D

  Explanation: Since there is no read cache in all-flash vSAN clusters, the I/O flow is subtlety different when compared to a read operation on hybrid configurations. On an all-flash vSAN, when a read is issued, the write buffer is first checked to see if the block is present References: https://www.vsan-essentials.com/chapter-5-architectural-details
