VMware vSphere 7.x Advanced Design (VCAP-DCV Design 2021) — Question 20

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?

Answer options

• A. Two new Fibre Channel storage arrays will be deployed, one at either site. Each application tier will be initially provisioned a new LUN. Data replication will be offloaded to the new arrays.
• B. Two new vSphere clusters enabled with vSAN will be deployed, one at either site. 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.
• C. Two new ISCSI storage arrays will be deployed, one at either site. Each application tier will be initially provisioned a new LUN. Data replication will be offloaded to the new arrays.
• D. 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 tier. Data replication will be offloaded to the new arrays.

Correct answer: D

Explanation

The correct answer is D because using vSphere Volumes (vVOLs) allows for policy-based management tailored to each application tier while ensuring that data replication is offloaded, satisfying the performance requirements. Options A and C do not meet the policy-based management needs, and option B, while it offers asynchronous replication, does not utilize vVOLs which are specifically required for this scenario.
