Full question →mediummultiple choiceObjective-mapped
A company runs a critical web application on Azure App Service in a single region. They need to achieve high availability across regions with automatic failover in the event of a regional outage. Which approach should they recommend?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Deploy multiple App Service instances in the same region with Traffic Manager
Incorrect. This provides redundancy within a single region but does not protect against a regional outage.
B
Best answer
Deploy to multiple regions with Azure Front Door
Correct. Azure Front Door can route traffic across regions and automatically fail over to a healthy region if the primary goes down.
C
Distractor review
Use App Service auto-scaling rules to handle increased load
Incorrect. Auto-scaling adjusts capacity within a region, it does not provide cross-region failover.
D
Distractor review
Enable Azure Site Recovery for the App Service
Incorrect. Azure Site Recovery is designed for virtual machines, not for Azure App Service workloads.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

FAQ
Questions learners often ask
What does this AZ-305 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Deploy to multiple regions with Azure Front Door — Deploying the web app to multiple regions and using Azure Front Door as a global load balancer provides automatic failover based on health probes, ensuring high availability across regions. Traffic Manager is DNS-based and slower to failover.
