Full question →mediummultiple choiceObjective-mapped
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. The application consists of a single App Service instance. Which Azure DDoS Protection tier should they enable to meet this requirement while minimizing cost?
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
Basic
DDoS Protection Basic is free and automatically included for all Azure resources. It provides protection against common network-layer attacks, making it the simplest and most cost-effective choice for a single web application.
B
Distractor review
Standard
DDoS Protection Standard is a paid tier that offers enhanced features like adaptive tuning, detailed metrics, and protection for multiple virtual networks. It is not required for a single App Service instance and would incur unnecessary cost.
C
Distractor review
Premium
There is no 'Premium' tier for Azure DDoS Protection. The available tiers are Basic and Standard.
D
Distractor review
No protection is needed because Azure App Service is inherently protected against DDoS attacks.
While Basic protection is automatic, it is not correct to say no protection is needed. Basic is sufficient, but it is a form of protection.
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: Basic — Azure provides two DDoS Protection tiers: Basic and Standard. The Basic tier is automatically enabled for all Azure services at no additional cost and provides protection against common network-layer attacks. For a single application, the Basic tier is sufficient to meet the requirement of protecting against Layer 3/4 attacks. The Standard tier offers additional benefits such as adaptive tuning, attack analytics, and cost protection for scaled resources, but it is only needed for larger deployments or for workloads that require enhanced guarantees and support.
