Click the Exhibit button.

A customer has a 4-node cluster and wants to know what will happen to their data if one of the two HA pairs goes down. Epsilon is configured and working properly and is owned by Node1. Nodes 3 and 4 have failed as shown in the exhibit.
What happens to the customer's data that is owned by the HA pair 3 and 4?

  • A. Nodes 1 and 2 will takeover the storage for nodes 3 and 4 and continue running normally.
  • B. The cluster will go into maintenance mode and only allow administrators access to data on nodes 1 and 2.
  • C. The entire cluster will panic and no data will be accessible.
  • D. The customer will lose access to the data on nodes 3 and 4 but will still have access to storage in nodes 1 and 2.

Suggested Answer: A 🗳️
An HA pair is two storage systems (nodes) whose controllers are connected to each other directly. In this configuration, one node can take over its partner's storage to provide continued data service if the partner goes down.

Correct answer is D Node 1 and 2 still provide access to its owned local storage. Access to storage from node 3 and 4 are not part of the failover so client will loose connection to it. D. The customer will lose access to the data on nodes 3 and 4 but will still have access to storage in nodes 1 and 2.
