A company runs a public-facing web application on Azure App Service in the West US region. They want to protect against network-layer (Layer 3/4) DDoS attacks and have a single web application. Which Azure DDoS Protection tier should they use?
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
Best answer
DDoS Protection Basic (default)
DDoS Protection Basic is always on for all Azure resources and provides automatic detection and mitigation of common network-layer DDoS attacks. No configuration is needed, and it is adequate for a single web app.
B
Distractor review
DDoS Protection Standard
DDoS Protection Standard must be enabled on a virtual network and provides enhanced mitigation capabilities, dedicated traffic monitoring, and cost protection. It is not required for a single App Service because Basic already covers network-layer attacks.
C
Distractor review
Azure Web Application Firewall (WAF) on Application Gateway
WAF protects against application-layer attacks (Layer 7) like SQL injection, not network-layer DDoS attacks. It can be used alongside DDoS Protection but does not replace it.
D
Distractor review
Azure Front Door with DDoS Protection Standard
Front Door provides global load balancing and can have DDoS Protection Standard enabled on its associated virtual network, but this is an unnecessary for the stated requirement for a single App Service and incurs additional cost. Basic remains the default and sufficient option.
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-500 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: DDoS Protection Basic (default) — DDoS Protection Basic is automatically enabled for all Azure resources at no additional cost. It continuously monitors and mitigates common network-layer attacks at the Azure edge. For a single App Service instance, Basic is sufficient. DDoS Protection Standard would require a virtual network and is typically used for larger, multi-tier architectures or when additional diagnostics and cost benefits are needed.
