VMware vSphere 6 Beta Foundations — Question 10

The following are the configuration details of a 12-node all-flash VSAN cluster:
✑ Every node has one disk group
✑ Each disk group consists of one cache device and six capacity devices
Which two methods can be used to increase the size of the cache tier in each host? (Choose two.)

Answer options

• A. Promote a capacity device to a cache device so that each disk group has two cache devices.
• B. Add a new cache device to the host. Reconfigure the host to have two disk groups with one cache device and three capacity devices per disk group.
• C. Add a second cache device to each disk group.
• D. Replace the existing cache device in each disk group with a larger cache device.

Correct answer: C, D

Explanation

The correct answers are C and D because adding a second cache device enhances the cache tier's size directly, while replacing the existing cache device with a larger one also increases capacity. Options A and B are incorrect as they do not conform to the requirement of increasing the cache tier size effectively within the current disk group configuration.
