RabbitMQ - Clustering

AMessages remain accessible on nodeA and nodeC due to queue mirroring

BAll messages on nodeB are lost immediately without recovery

CThe cluster stops processing messages until nodeB is restored

DMessages are automatically redirected to an external backup server

Step-by-Step Solution

Solution:

Step 1: Identify queue mirroring in RabbitMQ clusters
Mirrored queues replicate messages across multiple nodes.
Step 2: Analyze node failure impact
If nodeB fails, mirrored queues on nodeA and nodeC still hold the messages.
Final Answer:
Messages remain accessible on nodeA and nodeC due to queue mirroring -> Option A
Quick Check:
Mirroring ensures message availability despite node failure [OK]

Quick Trick: Mirrored queues keep messages available on surviving nodes [OK]

Common Mistakes:

MISTAKES

Assuming messages are lost when one node fails
Believing the cluster halts all operations on node failure
Thinking messages redirect to external backups automatically
