An architect is planning the physical server configuration for a vSAN-based infrastructure.
Which operations mode should a RAID controller support to minimize potential server downtime during physical disk failures?

1. A. RAID controller with Passthru mode
2. B. RAID controller with RAID 5 mode
3. C. RAID controller with RAID 10 mode
4. D. RAID controller with RAID 6 mode

Correct Answer: D

An architect has 50 ESXi hosts to deploy and DHCP servers are not allowed on any network. Which automated host deployment method should the architect use?

1. A. Stateless vSphere Auto Deploy
2. B. Stateful vSphere Auto Deploy
3. C. Scripted installation
4. D. Interactive installation

Correct Answer: C

An architect is tasked with designing a new VMware software-defined data center (SDDC) using VMware vSAN. The architect uses a storage assessment tool to determine the storage requirements for the new vSAN cluster. The new SDDC is going to be deployed into the existing data center and must be connected to a shared core network switch.
The architect decides to use vSAN ReadyNodes with the following configuration:
Two disk groups with:
Write Intensive NVMe 800 GB drive for cache
Four 3.84 TB Mixed Use NVMe for capacity
Four 10 GbE ports
Which element represents a risk that should be included in this design?

1. A. The number of 10 GbE capable ports in the vSAN ReadyNode
2. B. The use of vSAN ReadyNodes
3. C. The existing network is 10 GbE capable
4. D. The use of NVMe drives for cache and capacity

Correct Answer: C

An architect is designing a new VMware solution for a customer that has a number of different resource
profiles.
The following are the business requirements for the design:
The solution must support virtual machines with the following storage profiles:
-Write-intensive
-Backup
-Write-Once-Read-Many (WORM) archive
The solution must support migration of virtual machine disks between storage profiles.
The WORM archive data must be located at an isolated secure site.
The backup storage array must only be connected to a backup media server.
All data should be recoverable from backup.
Which design decision should the architect make to meet the business requirements?

1. A. The solution will leverage a single storage array for the WORM archive and write-intensive storage profiles
2. B. The solution will leverage the same array for the backup and write-intensive storage profiles
3. C. The solution will leverage a different array for each storage profile
4. D. The solution will leverage a single storage array for all storage profiles

Correct Answer: C

An architect is designing storage for a new vSphere environment to meet the following requirements: Asynchronous replication is required between two sites.
The impact on the storage layer should not impact the performance of the compute layer.
Each application tier will require different replication attributes.
Virtual machine live migration across compute and storage must be supported.
Virtual machine aware back up will be leveraged.
Operational management overhead should be minimized.
Operational automation should be supported.
Which storage design recommendations would meet the requirements?

1. A. Two new Fibre Channel storage arrays will be deployed, one at either site.Each application tier will be initially provisioned a new LU
2. B. Data replication will be offloaded to the new arrays.
3. C. Two new vSphere clusters enabled with vSAN will be deployed, one at either sit
4. D. vSAN will be used to provide policy-based management for each application tier.vSphere Replication will be used to replicate the virtual machine data in an asynchronous configuration.
5. E. Two new ISCSI storage arrays will be deployed, one at either site.Each application tier will be initially provisioned a new LU
6. F. Data replication will be offloaded to the new arrays.
7. G. Two new storage arrays will be deployed, one at either site.vSphere Volumes (vVOLs) will be used to provide policy-based management for each application tie
8. H. Data replication will be offloaded to the new arrays.

Correct Answer: B
