Question 1

Which Azure Front Door feature protects web applications from common threats like SQL injection and cross-site scripting?

Accepted Answer

Web Application Firewall (WAF) policy

Answer

A WAF policy attached to an Azure Front Door profile inspects HTTP/S requests and blocks or logs malicious patterns such as SQLi and XSS.

Question 2

You need to distribute traffic across VMs in a single region using a private IP frontend. Which Load Balancer type should you use?

Accepted Answer

An Internal (private) Load Balancer uses a frontend IP from a VNet subnet and is not reachable from the internet.

Question 3

What is the primary difference between Azure Front Door and Azure Traffic Manager for global load balancing?

Accepted Answer

Front Door operates at Layer 7 (HTTP/S) with anycast; Traffic Manager operates at Layer 4 DNS resolution

Answer

Front Door is a Layer 7 anycast proxy with caching and WAF, while Traffic Manager is a DNS-based Layer 4 load balancer that redirects clients to endpoints.

Question 4

Which Azure Load Balancer health probe setting determines how many consecutive failures mark a backend as unhealthy?

Accepted Answer

Unhealthy threshold

Answer

The unhealthy threshold specifies the number of consecutive probe failures required before the load balancer removes a backend from rotation.

Question 5

You want Azure Front Door to send traffic to a secondary origin group only when the primary origin group is unhealthy. What feature enables this?
