Citrix Virtual Apps and Desktops 7 Assessment, Design and Advanced Configurations — Question 37

Scenario: A Citrix Architect needs to manage the disaster recovery (DR) process for a Citrix Virtual Apps and Desktops environment. The environment currently consists of an active data center typically accessed by users, and a DR data center used in the event that a disaster impacts the primary data center.
Management has made it a priority to minimize the loss of data when failing over between data centers.
The environment has failed over from the primary data center to the DR data center and the primary data center has subsequently been recovered to its normal state.
What is the appropriate sequence of steps that the architect should follow to return to normal operations after the primary data center's stability is confirmed?

Answer options

• A. Complete replication to the primary data center, block access to the DR data center, terminate/drain existing sessions in the DR data center, configure replication back to the DR data center, and enable access in the primary data center.
• B. Terminate/drain existing sessions in the DR data center, complete replication to the primary data center, block access to the DR data center, enable access in the primary data center, and configure replication back to the DR data center.
• C. Block access to the DR data center, terminate/drain existing sessions in the DR data center, complete replication to the primary data center, configure replication back to the DR data center, and enable access in the primary data center.
• D. Block access to the DR data center, complete replication to the primary data center, terminate/drain existing sessions in the DR data center, enable access in the primary data center, and configure replication back to the DR data center.
• E. Terminate/drain existing sessions in the DR data center, block access to the DR data center, complete replication to the primary data center, configure replication back to the DR center, and enable access in the primary data center.
• F. Complete replication to the primary data center, terminate/drain existing sessions in the DR data center, block access to the DR data center, enable access in the primary data center, and configure replication back to the DR data center.

Correct answer: C

Explanation

The correct answer is C, as it ensures that access to the DR data center is blocked, which prevents further session activity that could result in data inconsistency. Terminating/draining sessions in the DR data center before completing replication to the primary data center ensures that only the latest data is synchronized. The other options either allow sessions to continue in the DR data center or do not correctly prioritize the sequence of actions needed for a smooth transition back to normal operations.
