RabbitMQ - Clustering

How does RabbitMQ clustering enhance fault tolerance in message delivery?

ABy storing all messages on a centralized database outside the cluster

BBy limiting message delivery to a single node to reduce complexity

CBy disabling message acknowledgments to speed up processing

DBy replicating queues across multiple nodes to avoid single points of failure

Step-by-Step Solution

Solution:

Step 1: Understand clustering in RabbitMQ
Clustering connects multiple RabbitMQ nodes to work as a single logical broker.
Step 2: Identify fault tolerance mechanism
Queues can be mirrored across nodes, so if one node fails, messages remain available on others.
Final Answer:
By replicating queues across multiple nodes to avoid single points of failure -> Option D
Quick Check:
Replication ensures fault tolerance [OK]

Quick Trick: Replication across nodes prevents single points of failure [OK]
