A company plans to deploy a multi-tier application on Azure. The web tier requires SSL termination and health probes. The application tier must be isolated from the internet. The database tier requires high availability. They want to minimize administrative overhead and use Azure native services. Which architecture should they recommend?
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 for web tier, Azure Load Balancer (internal) for application tier, and Azure SQL Database with active geo-replication
Application Gateway handles SSL termination and probes; internal Load Balancer keeps app tier private; SQL Database active geo-replication provides HA.
B
Distractor review
Azure Front Door for web tier, Azure Load Balancer for database tier, and SQL Server on Azure VMs with Always On
Front Door is global and not needed for a single-region web tier; Load Balancer is for network traffic, not database tier; SQL Server on VMs adds overhead.
C
Distractor review
Azure Traffic Manager for web tier, Azure Application Gateway for database tier, and Azure SQL Database with failover groups
Traffic Manager is DNS-based and doesn't provide SSL termination; Application Gateway is not a database load balancer.
D
Distractor review
Azure Application Gateway for web tier, Azure Load Balancer (internal) for application tier, and Azure SQL Database with geo-restore
Geo-restore is for point-in-time recovery from a backup, not for high availability with automatic failover.
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 for web tier, Azure Load Balancer (internal) for application tier, and Azure SQL Database with active geo-replication — Azure Application Gateway provides SSL termination, health probes, and Web Application Firewall at Layer 7 for the web tier. An internal Azure Load Balancer distributes traffic to the application tier while keeping it isolated. Azure SQL Database with active geo-replication offers high availability for the database with automatic failover. The other options either misplace services or do not meet all requirements.
