This AZ-305 practice question tests your understanding of design business continuity solutions. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company needs to design a disaster recovery solution for a multi-tier application that includes a web tier, a business tier, and a database tier. The solution must meet the following requirements: - RPO of 15 minutes for the database - RTO of 1 hour for the entire application - Automatic failover for the database - No data loss for the web and business tiers (stateless) Which TWO services should be included in the solution? (Choose two.)
Azure Backup
Why wrong: Does not provide automatic failover.
Azure Traffic Manager
Routes traffic to healthy region for stateless tiers.
Azure Site Recovery for VM replication
Why wrong: Not needed for stateless tiers; can use traffic manager and redeploy.
Azure Front Door
Why wrong: Overkill for a single-region DR; Traffic Manager is simpler.
Azure SQL Database active geo-replication
Provides automatic failover with low RPO.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Azure Traffic Manager
Option B and Option D are correct. Azure SQL Database active geo-replication provides automatic failover with an RPO of 5 seconds, well within 15 minutes. Azure Traffic Manager can route traffic to the secondary region stateless tiers. Option A is wrong because Azure Site Recovery is not needed for stateless tiers; they can be redeployed. Option C is wrong because Azure Front Door is not necessary for a simple DR scenario. Option E is wrong because Azure Backup does not provide automatic failover.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
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.
Detailed technical explanation
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
