Veeam Certified Engineer (VMCE) v12 — Question 117

After performing a failover to a disaster recovery site, it is decided that the virtual machines need to be failed back to the original production site, and that any changes made during the failover should be discarded.

Which option should be used?

Answer options

• A. Commit tailback
• B. Failback
• C. Undo failover
• D. Undo failback

Correct answer: C

Explanation

The correct answer is 'Undo failover' because it allows for reverting the virtual machines back to the original state before the failover, discarding any changes made during that time. 'Failback' suggests a normal return process without discarding changes, while 'Undo failback' does not apply as it refers to reversing a failback action, which is not the situation here. 'Commit tailback' is not relevant to the failover process.
