What is the purpose of the DRBD metadata storage?

To store information about the DRBD resource's state, such as generation numbers and bitmap.

To store the actual replicated data.

To store the DRBD configuration file.

To store log files for DRBD operations.

What is the primary role of LINSTOR in a storage environment?

To replace DRBD with a proprietary replication solution.

To provide a backup solution for DRBD devices.

To provide a distributed file system.

To manage and provision DRBD resources across a cluster of nodes.

A Pacemaker cluster uses a DRBD resource as the backing store for a filesystem that is mounted on the active node. The administrator wants to ensure that the filesystem is only mounted on the node that is currently Primary for the DRBD resource. Which Pacemaker configuration should be used?

Configure the DRBD resource as a multi-state resource and rely on Pacemaker to automatically mount the filesystem on the Primary node.

Use a clone resource for the filesystem that runs on all nodes.

Create a location constraint that forces the filesystem to run on a specific node.

Create a colocation constraint that places the filesystem resource with the DRBD resource, and an order constraint that starts the DRBD resource before the filesystem.

What is the role of the DRBD resource agent in a Pacemaker cluster?

It replaces the need for DRBD configuration files.

It automatically promotes both nodes to Primary.

It provides a web interface for DRBD management.

It manages the DRBD resource as a cluster resource, allowing Pacemaker to control its state.

A system administrator is explaining DRBD to a colleague. They want to emphasize that DRBD operates at the block level, replicating writes to a remote node. Which statement correctly describes the DRBD architecture?

DRBD is a userspace daemon that copies files to a remote node.

DRBD is a storage area network (SAN) protocol.

DRBD is a kernel module that intercepts block I/O requests and replicates them to a peer node.

DRBD is a network filesystem that provides shared storage to multiple clients.

362.1 DRBD (weight: 6) LPIC-3-HIGH-AVAILABILITY Practice Questions (Page 3)

Part of the Topic 362: High Availability Cluster Storage domain, which makes up ~26% of our current practice bank. Linux Professional Institute does not publish an official question count, but from its 90-minute exam (~35–60 total, ~9–16 in this domain), expect 3–5 from this objective — we provide 32 practice questions to prepare you well beyond it.
