Question
An administrator receives many complaints about increased boot times from a WI user over the past few days. Upon further review, the administrator discovers delays in the deployments of VD' desktops. The administrator could not find any indications that the cluster resources are insufficient. What should the administrator verify to resolve this issue?
Options
- AErasure Coding was disabled
- BIf a node failed
- CIf Shadow Clone was disabled
- DIf Memory Overcommitment was disabled

Explanation
Shadow Clone (C) is a Nutanix feature specifically designed to accelerate VDI boot storms. It detects when multiple VMs are reading the same data (e.g., a shared base disk image during boot) and creates a local copy of that data on each host's storage tier, reducing cross-node network I/O. If Shadow Clone is disabled, all VMs must fetch base image blocks across the network from the CVM that holds the data, causing significant boot-time delays and slow desktop deployments - even when overall cluster CPU and memory appear sufficient. Erasure Coding (A) affects storage efficiency, not boot performance. A failed node (B) was already ruled out by the resource check. Memory Overcommitment (D) would affect runtime performance, not boot time.
