A financial services company runs a critical SQL Server database on Azure Virtual Machines. They require a disaster recovery solution with an RPO of less than 15 seconds and an RTO of less than 1 hour. Which technology 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 Site Recovery
Incorrect. Azure Site Recovery typically has an RPO of several minutes, which does not meet the sub-15-second requirement.
B
Best answer
SQL Server Always On Availability Groups
Correct. Always On Availability Groups with synchronous replication can provide an RPO of zero and an RTO of seconds to minutes, satisfying the disaster recovery requirements.
C
Distractor review
Azure Backup for SQL Server
Incorrect. Azure Backup provides point-in-time restore but has a typical RPO of hours and RTO that is not suitable for sub-1-hour recovery.
D
Distractor review
Geo-redundant backups
Incorrect. Geo-redundant backups are for storage-level redundancy and do not provide the required low RPO/RTO for a SQL Server database.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

FAQ
Questions learners often ask
What does this AZ-305 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: SQL Server Always On Availability Groups — SQL Server Always On Availability Groups with synchronous commit mode can achieve very low RPO (near zero) and fast failover (RTO typically under a minute), meeting the stringent requirements. Other options like Azure Site Recovery or Azure Backup have higher RPO/RTO.
