Step-by-Step Solution
Solution:
Step 1: Identify queue type for message safety
Quorum queues replicate messages across nodes, protecting against node crashes.Step 2: Check durability setting
Durable=true ensures messages survive broker restarts, important for message safety.Step 3: Evaluate other options
Classic queues with durable=false or exclusive=true do not guarantee safety; lazy queues with auto-delete=true remove queues automatically.Final Answer:
Quorum queue with x-queue-type set to quorum and durable=true -> Option BQuick Check:
Quorum + durable=true = message safety [OK]
Quick Trick: Use quorum queue with durable=true for safety [OK]
Common Mistakes:
MISTAKES- Using classic queues without durability
- Confusing lazy or exclusive queues with safety features
- Ignoring durable setting
