QuestionQ82

Performance-tuning, Optimization, and Upgrades

A large enterprise operates a main campus with two eight-node vSAN clusters and 50 remote sites, each with one two-node cluster. An administrator configures a vLCM desired image for lifecycle management, and vLCM determines that every cluster requires remediation.

How would vLCM improve the remediation operation in this scenario?

  • A When the administrator selects remediate, vLCM will non-disruptively remediate more than one server at the same time in a single cluster.
  • B The administrator can remediate all remote sites and the main campus concurrently.
  • C vLCM cannot remediate the clusters concurrently, so the administrator must complete the sites one-by-one in a parallel manner.
  • D The administrator should remediate the main campus using vSphere Update Manager (VUM) and the 50 remote sites using vLCM.
Explanation

A vLCM desired image can remediate up to 64 clusters in parallel. The 52 clusters in this environment can therefore be remediated concurrently, while vSAN hosts within an individual cluster are remediated sequentially to preserve vSAN data availability and synchronization.
