• Question 45:

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

• Question 46:

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

• Question 47:

  An administrator managing a vSAN cluster of six-nodes with policy FTT-2/RAID-6 decided to put one of the nodes in maintenance mode using the “Full-data migration” option. What will happen after this action is taken?

  A. The host will enter in maintenance mode and the data will remain accessible until the host exits maintenance mode.
  B. The system will prompt to add an additional host to the cluster in order to preserve the policy compliance.
  C. The host will enter in maintenance mode and only data with no redundancy will remain accessible.
  D. The host will enter into maintenance mode if both components of a certain object are residing on that host, then one of the components will be moved to another available host.
  A. The host will enter in maintenance mode and the data will remain accessible until the host exits maintenance mode.

• Question 48:

  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?

  A. 6
  B. 4
  C. 5
  D. 8
  A. 6

• Question 49:

  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. Create an HCI Mesh using the first cluster's datastore.
  B. Obtain additional free capacity from the existing NAS storage.
  C. Obtain additional free capacity from the existing FC storage.
  D. Create an HCI Mesh using the second cluster's datastore.
  B. Obtain additional free capacity from the existing NAS storage.

• Question 50:

  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.)

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