Step-by-Step Solution
Solution:
Step 1: Recall Bulkhead pattern effect
Bulkhead isolates failures to prevent system-wide impact.Step 2: Apply to instance failure scenario
Only the failed instance is affected; others keep working normally.Final Answer:
Only the failing instance is affected; others continue working -> Option DQuick Check:
Bulkhead isolates failures = Only the failing instance is affected; others continue working [OK]
Quick Trick: Bulkhead isolates failure to single instance [OK]
Common Mistakes:
- Assuming all instances fail together
- Thinking instances merge automatically
- Believing retries happen without isolation
