QuestionQ1

Data Storage Software

Refer to the exhibit.

Question Image

The customer has expanded Cluster A by adding a new HA pair. The customer cannot replicate data from the new HA pair to Cluster B or Cluster C.

Which two actions will fix the problem?

Choose two
Explanation

Intercluster replication uses intercluster LIFs, not management LIFs. Each node requires an intercluster LIF in each IPspace used for peering. Because Cluster A uses IPspace AB to communicate with Cluster B and IPspace AC to communicate with Cluster C, the two nodes in the new HA pair need two additional intercluster LIFs in both IPspaces.

Self-encrypting drives provide hardware-based encryption for data at rest. Their encrypted contents cannot be read without the drive’s encryption key, protecting the data if the storage device is repurposed, returned, misplaced, or stolen.
