Question 1

A company runs a fleet of Linux Virtual Machines in Azure.

They need to implement a backup solution. The application running on the VMs caches significant amounts of data in memory. If a backup is taken while data is in memory but not yet written to disk, restoring that backup could lead to application corruption.

You need to ensure that backups capture all data in memory and pending I/O operations are flushed to disk before the snapshot is taken.

What type of backup must you configure?

Accepted Answer

Understand the difference between crash-consistent (disk only) and application-consistent (memory flushed to disk).

Question 2

What mistakes do candidates make on this AZ-305 question?

Accepted Answer

Confusing crash-consistent with application-consistent. Crash-consistent is fine for simple file servers, but dangerous for databases or memory-heavy apps.
