Question 76

During a vSAN design workshop, an architect collected the following customer requirements:

• Reduce the impact of a disk failure on a vSAN capacity node.

• Reduce the need for a rebuild upon a disk failure.

• Achieve the best performance for application workloads.

• Leverage the amount of available vSAN space efficiently.

The customer has already purchased all hardware and therefore the vSAN 7.0 U1 cluster is constrained to one Disk Group per node.

Which vSAN cluster option should the architect enable to meet these requirements?

    Correct Answer: A

    To meet the requirements of reducing the impact of a disk failure, reducing the need for a rebuild upon a disk failure, achieving the best performance for application workloads, and leveraging the amount of available vSAN space efficiently, the most appropriate choice would be enabling Deduplication and Compression. Deduplication and Compression improve the space efficiency by eliminating redundant data and compressing the data, thereby maximizing the available vSAN space. Additionally, it can enhance the performance by reducing the amount of data that needs to be read from and written to disk. This aligns well with the constraints of having only one Disk Group per node, as it maximizes the use of the existing hardware. Consequently, Deduplication and Compression is the best option to meet all the specified requirements.
