Based on the exhibit, which snapshot characteristic will result in performance degradation?

Refer to the exhibit.

A cloud administrator is investigating a reported performance issue on a virtual machine (VM). The administrator observes low latency on the datastore but high latency within the VM. The administrator notes that it is a standard operating procedure to take a snapshot of the VM whenever there is an application or operating system upgrade on this VM.

Based on the exhibit, which snapshot characteristic will result in performance degradation?
A . Snapshot chain length
B . Snapshot size
C . Snapshot type
D . Snapshot age

Answer: A

Follow these recommendations to get the best performance when using snapshots:

・ Use snapshots as a temporary measure only.

The presence of snapshots can have a significant impact on guest application performance, especially in a VMFS environment, for I/O intensive workloads. The guest applications fully recover performance after snapshots are deleted.

・ Keep the snapshot chain length short when possible, to minimize the guest application performance impact.

Performance degradation is higher as the snapshot chain length increases.

・ If you need to increase the size of a virtual disk that has snapshots associated with it, you must delete the snapshots first before you can increase the virtual disk’s size.
