A company runs a web application on Azure App Service with a backing Azure SQL Database in a single region. They need to ensure availability during an Azure region outage. The solution must automatically fail over the entire application stack with minimal data loss and redirect user traffic to the secondary region. Which combination of Azure services should they implement?
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
Distractor review
Azure Traffic Manager with active-passive and geo-replication for Azure SQL Database
Traffic Manager can route traffic but does not provide HTTP-level routing or WAF capabilities. Geo-replication for SQL Database alone does not provide automatic failover; auto-failover groups are needed.
B
Best answer
Azure Front Door with active-active or active-passive routing and auto-failover groups for Azure SQL Database
Azure Front Door provides global HTTP/HTTPS routing with health probes and automatic failover, and auto-failover groups for SQL Database provide geo-replication with automatic failover, meeting RPO and RTO requirements.
C
Distractor review
Azure Application Gateway with backend pools in multiple regions and SQL Database failover groups
Azure Application Gateway is a regional load balancer and cannot route traffic across regions globally.
D
Distractor review
Azure Load Balancer with multiple regions and Azure SQL Database automatic failover
Azure Load Balancer is a regional layer-4 load balancer and cannot handle cross-region traffic routing.
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 Front Door with active-active or active-passive routing and auto-failover groups for Azure SQL Database — Azure Front Door provides global load balancing and traffic routing with health probes and automatic failover. For the database, auto-failover groups enable geo-replication with automatic failover and RPO of seconds to minutes. Traffic Manager can also do global routing but Front Door is better for web applications with HTTP/HTTPS. Application Gateway is regional. Azure Load Balancer does not provide global routing.
