Full question →mediummultiple choiceObjective-mapped
A company is building a new application that requires a fully managed relational database. The application has varying workloads across different databases. The company wants to pool resources to optimize cost and allow each database to scale as needed. They also need automated backups with point-in-time restore and geo-replication for disaster recovery. Which Azure data 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 SQL Database
Azure SQL Database supports elastic pools for resource sharing among databases, automated backups, point-in-time restore, and active geo-replication for disaster recovery.
B
Distractor review
Azure SQL Managed Instance
Managed Instance provides near 100% SQL Server compatibility but does not support elastic pools. It is better suited for migrations requiring instance-scoped features.
C
Distractor review
Azure Database for MySQL
Azure Database for MySQL is a fully managed MySQL database, but it does not provide elastic pools for sharing resources across databases.
D
Distractor review
Azure Database for PostgreSQL
Azure Database for PostgreSQL is a fully managed PostgreSQL service, but it lacks elastic pool functionality.
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 SQL Database — Azure SQL Database supports elastic pools, which allow multiple databases to share resources in a pool, optimizing cost. It also provides built-in backup, point-in-time restore, and active geo-replication. Azure SQL Managed Instance offers more compatibility but lacks elastic pools. Azure Database for MySQL/PostgreSQL are fully managed but do not offer elastic pools natively.
