A microservice logs show frequent timeouts due to slow downstream services. What is the best immediate action to improve system stability?
AImplement fallback responses and circuit breakers
BMerge services to reduce network calls
CRemove retries to reduce load
DIncrease timeout values to wait longer
Step-by-Step Solution
Solution:

  1. Step 1: Analyze timeout cause

    Slow downstream services cause timeouts, risking cascading failures.

  2. Step 2: Choose best immediate fix

    Fallbacks and circuit breakers prevent overload and provide graceful degradation.

  3. Final Answer:

    Implement fallback responses and circuit breakers -> Option A

  4. Quick Check:

    Timeout fix = Fallback and circuit breaker [OK]
Quick Trick: Use fallback and circuit breaker for slow services [OK]
Common Mistakes:
  • Increasing timeout causing longer waits
  • Removing retries without fallback
  • Merging services causing complexity
