Veeam Certified Engineer (VMCE) 2020 — Question 20

The backup administrator configured replication for a VM from Data Center 1 to Data Center 2, which runs every day at 1 a.m. A power surge takes out Data
Center 1 at 7 a.m. and the administrator fails over the replica at 8 a.m. When the power comes back on, the administrator performs the `failback` action at 2 p.m. and checks the state of the original VM. They recognize that not all data is available. What is missing?

Answer options

• A. Data from 1 a.m. to 7 a.m.
• B. Data from 1 a.m. to 2 p.m.
• C. Data from 8 a.m. to 2 p.m.
• D. Data from 7 a.m. to 8 a.m.

Correct answer: B

Explanation

The correct answer is B because the data generated after the last successful replication at 1 a.m. and before the failback at 2 p.m. was not captured in the replication process. Option A includes data that was replicated before the power surge, while C and D refer to periods after the failover that do not affect the original VM's data integrity.
