Step-by-Step Solution
Solution:

  1. Step 1: Understand UnhealthyThresholdCount meaning

    This value defines how many consecutive failed health checks mark a target unhealthy.

  2. Step 2: Compare failure count with threshold

    Since 4 failures exceed the threshold of 3, the target is marked unhealthy.

  3. Final Answer:

    Unhealthy -> Option A

  4. Quick Check:

    Failures > UnhealthyThresholdCount = Unhealthy [OK]
Quick Trick: Failures above threshold mark target unhealthy [OK]
Common Mistakes:
  • Assuming target remains healthy after failures
  • Confusing unhealthy with draining or unknown
