Step-by-Step Solution
Solution:
Step 1: Understand network partition impact
Network partition means datacenters cannot talk but still operate independently.Step 2: Analyze client connection behavior
Clients connected to reachable datacenter still get data, so availability remains.Final Answer:
Availability is maintained if clients connect to the reachable datacenter -> Option DQuick Check:
Network partition + client reachability = availability maintained [OK]
Quick Trick: Clients must connect to reachable datacenter during partition [OK]
Common Mistakes:
- Assuming total availability loss on partition
- Believing Kafka auto-merges conflicting data
- Thinking data is deleted during partition
