AZ-204 Practice Question: Connect to and consume Azure services and third-party services
An application calls a Service Bus topic through HTTP. The developer must implement retries without overwhelming the remote system during partial outages. Which retry pattern is best?
⚠ Common exam trap
Candidates often confuse 'exponential backoff' with 'immediate retries' or 'infinite retries,' overlooking the critical need for jitter and a maximum retry limit to prevent overwhelming the remote system during partial outages.

Correct answer & explanation
✓
Exponential backoff with jitter and a maximum retry limit
Exponential backoff with jitter and a maximum retry limit is the best pattern because it progressively increases the delay between retries, preventing the client from overwhelming the Service Bus topic during partial outages. The jitter randomizes the delay to avoid thundering herd problems, while the maximum retry limit ensures the system doesn't retry indefinitely, aligning with Azure's recommended retry guidance for HTTP-based calls to Service Bus.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Disable all timeout settings
Why it's wrong here
Missing timeouts can cause thread starvation and cascading failures.
- ✗
Immediate infinite retries
Why it's wrong here
Infinite tight retries can amplify outages.
- ✗
Retry only after restarting the application
Why it's wrong here
Restarts are not a controlled resilience pattern.
- ✓
Exponential backoff with jitter and a maximum retry limit
Why this is correct
Backoff with jitter reduces retry storms and gives the remote service time to recover.
