Full question →mediummultiple choiceObjective-mapped
A company deploys a web application on Azure VMs in an availability set. They need to expose the application to the internet with SSL termination and health probes. Additionally, they need to protect against DDoS attacks and common web vulnerabilities. Which Azure service 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
Azure Application Gateway with Web Application Firewall (WAF) and DDoS Protection
Application Gateway offers SSL termination, health probes, WAF, and can be combined with DDoS Protection.
B
Distractor review
Azure Front Door with WAF and DDoS Protection
Front Door is a global service; for a single-region app, Application Gateway is more appropriate and cost-effective.
C
Distractor review
Azure Traffic Manager and Azure Load Balancer
Traffic Manager is DNS-based and does not handle SSL termination; Load Balancer works at Layer 4 without WAF.
D
Distractor review
Azure CDN with WAF
CDN is for content delivery, not a load balancer for the application itself; it lacks health probes.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this AZ-305 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Azure Application Gateway with Web Application Firewall (WAF) and DDoS Protection — Azure Application Gateway is a Layer 7 load balancer that provides SSL termination, health probes, and a built-in Web Application Firewall (WAF). It can also leverage Azure DDoS Protection (Basic is free, Standard optional). Azure Front Door is a global service, not needed for a single-region deployment. Traffic Manager and Load Balancer do not provide WAF or SSL termination at Layer 7.
