An administrator has recently added two additional nodes to an existing three-node Nutanix cluster, which hosts critical business application VMs. The administrator will tolerate losing up to two node

Question

Options

• AModify cluster to RF3
• BMigrate VMs to new RF3 container
• CConvert container to RF3
• DCreate a new RF3 container

• A
  80% (28)
• B
  14% (5)
• D
  6% (2)

Explanation

Tolerating the simultaneous loss of two nodes requires Replication Factor 3 (RF3), which stores three copies of all data across three different nodes. With RF3, the cluster can survive the failure of any two nodes and still have one surviving copy of every data block.

• Modify cluster to RF3 (A): The cluster-level replication factor setting must be changed from the default RF2 to RF3. This is done via the Prism Element cluster settings or CLI (ncli cluster edit-params ...).

• Convert container to RF3 (C): Existing storage containers must also be converted to RF3 so that data written to them is replicated three ways. Converting in place is the minimum-effort approach since the existing VMs remain in the same container.

• Migrate VMs to new RF3 container (B) is unnecessary if you convert the existing container (C) - migrating VMs would require vMotion/cold migration and additional downtime.

• Create a new RF3 container (D) would still require migrating all existing VMs into it (Option B), which is significantly more effort than an in-place conversion.
