LPIC-3 Exam 304 (Virtualization and High Availability) — Question 1

When using DRBD in a Pacemaker cluster, which configuration objects must be managed in order to use the DRBD device as storage for other cluster services?
(Choose TWO correct answers.)

Answer options

• A. A security resource in order to permit other cluster services to access the data on the DRBD device.
• B. A health resource in order to check the integrity of the file system.
• C. A file system resource to mount the device.
• D. A replication resource that synchronizes the DRBD device's data to all nodes that may take over the device after a failover.
• E. A constraint to ensure the device is mounted before the dependent services are started.

Correct answer: C, E

Explanation

The correct answers are C and E because a file system resource is necessary to mount the DRBD device for use, and a constraint ensures that this device is mounted before any services that rely on it are initiated. Options A, B, and D are not required specifically for the DRBD device to be utilized as storage for other services in the cluster.
