Application delivery

Azure Application Gateway

Regional Layer 7 load balancing, TLS termination, and web application firewall.

Key points

  • Application Gateway provides regional HTTP(S) routing, TLS termination, health probes, and optional WAF.
  • Listeners, certificates, path rules, backend pools, probes, subnet design, and WAF policy define the regional boundary.

Best-known use cases

  • Route private regional web traffic by path while protecting the application with a regional WAF.

What candidates often confuse it with

  • Application Gateway is regional Layer 7; Front Door operates at the global edge and Load Balancer handles Layer 4 flows.

Key takeaway

Choose Application Gateway for regional HTTP(S) delivery that needs path routing, TLS, or WAF near the backends.

Mode

Exam fidelity: Microsoft does not publish a fixed live question count or guarantee a question-type mix for AZ-305. This lane contains multiple-choice exam-style practice; no supplemental matching, ordering, or case-study exercises were needed. Practice percentages do not reproduce Microsoft's scaled scoring, and difficulty labels describe this site's Expert-level architecture and trade-off complexity rather than a Microsoft-published question rating.
