The answer is Azure Site Recovery, Azure Traffic Manager, and the test failover capability within Azure Site Recovery. This combination meets the strict RPO of 15 minutes and RTO of 1 hour because Site Recovery handles continuous replication and automated orchestration of failover to a secondary region, while Traffic Manager directs user traffic to the healthy region after failover. For non-disruptive DR testing, Site Recovery’s built-in test failover feature allows you to validate your recovery plan in an isolated environment without impacting production. On the AZ-305 exam, this scenario tests your ability to distinguish between disaster recovery orchestration (Site Recovery) and global traffic routing (Traffic Manager), versus backup tools like Azure Backup or advanced load balancers like Front Door. A common trap is choosing Front Door for failover routing, but Traffic Manager is the simpler, correct choice for region-level failover without needing application-layer acceleration. Memory tip: “Site for sync, Traffic for switch, Test for trust.”
AZ-305 Design infrastructure solutions Practice Question
This AZ-305 practice question tests your understanding of design infrastructure 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.
You are designing a disaster recovery (DR) solution for a critical application hosted on Azure VMs. The solution must meet the following requirements: - Recovery Point Objective (RPO) of 15 minutes. - Recovery Time Objective (RTO) of 1 hour. - Automatically fail over to a secondary region in the event of a regional outage. - Support for non-disruptive DR testing. Which THREE components should you include in the solution? (Choose three.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Azure Site Recovery test failover capability
Option A, Option B, and Option E are correct. Azure Site Recovery provides replication and orchestration of failover to a secondary region, meeting RPO of 15 minutes and RTO of 1 hour. Azure Traffic Manager can be used to route traffic to the secondary region after failover. Azure Site Recovery supports non-disruptive DR testing with test failover. Option C is wrong because Azure Backup is for backup, not DR with automatic failover. Option D is wrong because Azure Front Door is a global load balancer but does not provide DR orchestration; Traffic Manager is sufficient.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
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.
Detailed technical explanation
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
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.
