Given a federation upstream configured to share an exchange named logs from a remote RabbitMQ server, what will happen if a message is published to the local logs exchange?
AThe message will stay local and not be sent to the remote server
BThe message will be forwarded to the remote exchange automatically
CThe message will be received from the remote exchange and appear locally
DThe message will be duplicated on both local and remote exchanges
Step-by-Step Solution
Solution:
Step 1: Understand Federation direction
Federation pulls messages from remote to local, not the other way around.
Step 2: Analyze message flow
Publishing locally to the exchange does not send messages upstream; messages flow from remote to local only.
Final Answer:
The message will stay local and not be sent to the remote server -> Option A
Quick Check:
Federation pulls from remote; local publish stays local = B [OK]
Quick Trick:Federation pulls messages from remote to local, not vice versa [OK]
Common Mistakes:
MISTAKES
Thinking federation pushes messages upstream
Assuming messages duplicate automatically
Confusing federation with shovel direction
