                          Question #3

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

                          Question #4

                          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. The default gateway must be used as the only isolation address
                          • B. One of isolation addresses should reside in the site 1 data center
                          • C. Host isolation response must exclude the VMs required
                          • D. One isolation address reachable only from the witness appliance in both sites
                          • E. 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

                          Question #5

                          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 only data with no redundancy will remain accessible.
                          • B. The host will enter in maintenance mode and the data will remain accessible until the host exits maintenance mode.
                          • C. 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.
                          • D. The system will prompt to add an additional host to the cluster in order to preserve the policy compliance.
