RabbitMQ - Clustering
After setting up a RabbitMQ cluster, clients report connection failures when a node goes down. What should you check?
AIf the nodes are running on different operating systems.
BIf clients are configured to connect to multiple nodes.
CIf the cluster has only one node.
DIf the message encryption is enabled.
Step-by-Step Solution
Solution:

  1. Step 1: Understand client connection behavior

    Clients must be able to connect to multiple nodes to handle node failures.

  2. Step 2: Evaluate other options

    Single node cluster means no failover; OS differences and encryption don't cause connection failures on node down.

  3. Final Answer:

    If clients are configured to connect to multiple nodes. -> Option B

  4. Quick Check:

    Client failover needs multi-node config [OK]
Quick Trick: Configure clients for multi-node connection [OK]
Common Mistakes:
MISTAKES
  • Ignoring client connection settings
  • Assuming OS differences cause failures
  • Confusing encryption with connectivity
