Question # 1

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.

Question # 2

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?

A.

Enabling Resync Throttling

B.

Enabling Maintenance mode with no data evacuation

C.

Enabling automatic rebalance

D.

Setting the vSAN policy’s IOPS limit for object value to 0 (unlimited)

Question # 3

Which three steps are required to decommission a stretched cluster and convert it to a standard vSAN cluster? (Choose three.)

A.

Reinstall the ESXi hosts

B.

Remove the Fault Domain configuration

C.

Remove the vSAN partition schema on the disk groups

D.

Delete the witness host VM

E.

Repair the cluster objects

F.

Disable and remove the stretched cluster

Question # 4

An administrator is tasked with sharing storage from one vSAN cluster to another vSAN cluster. SPBM management must be preserved end-to-end, and the policy must be applied by the source vSAN cluster which is storing the data. Both vSAN clusters are managed by the same vCenter server.

What should the administrator configure?

A.

NFS volumes on vSAN

B.

iSCSI targets on vSAN

C.

HCI Mesh on vSAN

D.

vVOLs on vSAN

Question # 5

A vSAN policy has been configured with Erasure Coding on a vSAN stretched cluster.

Which RAID level and FTT setting have been specified?

A.

SFTT with RAID1

B.

PFTT with RAID1

C.

PFTT with RAID5/6

D.

SFTT with RAID5/6

Question # 6

An architect intends to use the Primary Level of Failures To Tolerate (PFTT) to calculate the minimum number of required hosts for a vSAN cluster.

Which calculation model should be used?

A.

1 * PFTT + 1

B.

2 * PFTT + 2

C.

1 * PFTT + 2

D.

2 * PFTT + 1

Question # 7

An architect is reviewing a vSAN cluster that has an unbalanced cluster configuration.

Which behavior will the architect observe?

A.

Consistent maintenance procedures

B.

Reduced predictability of storage performance

C.

Reduced deduplication capabilities

D.

Faster rebuild times

Question # 8

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

Question # 9

An architect is currently working with a customer to transform their existing ESXi hosts to vSAN nodes. The customer expressed the following requirements.

• First phase will transform 50% of the hosts to a hybrid vSAN nodes.

• Second phase will transform the remaining 50% hosts to an All-Flash vSAN nodes.

The following constraint exists:

• Each host has a 4-port x 1 GbE network interface.

Which two recommendations should the architect make to align with the customer ' s requirements? (Choose two.)

A.

Hybrid vSAN clusters can have shared 1 GbE network adapters.

B.

All-Flash vSAN clusters must have dedicated 10 GbE network adapters.

C.

Hybrid vSAN clusters must have dedicated 1 GbE network adapters.

D.

All-Flash vSAN clusters can have shared 10 GbE network adapters.

E.

Hybrid vSAN clusters must have dedicated 10 GbE network adapters.

Question # 10

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 storage

What should the architect recommend?

A.

vSAN iSCSI Target Service

B.

Stretched vSAN Cluster

C.

vSAN Direct

D.

vSAN File Services
