QUESTION 175

What is the process used to restore an entire cluster in the event of a catastrophic failure?

 

A.

Restore the first node by doing a fresh install, restore the first node database from DRS, and then restore the subsequent nodes from the DRS backup location.

B.

Restore the first node from tape or SFTP and then restore each subsequent node.

C.

Restore the first node and then perform a database push to the subsequent nodes in the cluster.

D.

Restore all the nodes in the cluster by means of a fresh install and then restore the features and subcomponents to each server by means of DRS.

 

Correct Answer: A

Explanation:

Disaster Recovery System Administration Guide

Before you restore a cluster, make sure that all nodes in the cluster are up and communicating with the first node. You must carry out a fresh install for the nodes that are down or not communicating with first node at the time of the restore. Restoring the first node restores the whole cluster database. This may take up to several hours based on number of nodes and size of database being restored. If a subsequent node is down or not connected to the cluster during the cluster restore, the database component restore will skip that node and proceed with the next one. You must carry out a fresh install of Cisco Unified Communications Manager on these subsequent nodes.

You can restore the whole cluster as a single operation. The first node and the subsequent nodes do not necessarily need to be restored in two separate operations.
