Microservices - Real-World Architecture Case Studies

Awhile(true) { callService() }

Bretry(count=-1) { callService() }

Cretry(0) { callService() }

Dretry(count=5) { callService() }

Step-by-Step Solution

Solution:

Step 1: Understand retry syntax with limits
Retries must have a positive count to limit attempts.
Step 2: Evaluate options
retry(count=5) { callService() } uses a positive count (5), valid retry limit; others are infinite or zero retries.
Final Answer:
retry(count=5) { callService() } -> Option D
Quick Check:
Positive retry count = correct syntax [OK]

Quick Trick: Retries need a positive count to avoid infinite loops [OK]
