The answer is options A, C, and D: testing failover regularly, using a recovery plan to orchestrate failover for multi-tier applications, and enabling replication for all critical VMs. These three practices form the backbone of a robust Azure Site Recovery business continuity strategy because they ensure your disaster recovery plan is validated, coordinated, and comprehensive. Testing failover without impacting production verifies that recovery time objectives are met, while recovery plans automate the correct startup order and dependencies for complex applications. Enabling replication for every critical VM guarantees no single point of failure is left unprotected. On the AZ-305 exam, this question tests your ability to distinguish between operational best practices and common misconfigurations—a frequent trap is assuming a single target region is sufficient, which can cause resource contention during a regional outage. Remember the mnemonic “T-R-E” for Test, Recover, Enable: test failovers, use recovery plans, and enable replication for all critical workloads.
AZ-305 Design business continuity solutions Practice Question
This AZ-305 practice question tests your understanding of design business continuity solutions. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
Which THREE of the following are best practices for designing a business continuity solution using Azure Site Recovery? (Select THREE.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Perform test failovers regularly to validate the recovery plan
Options A, C, and D are correct. Testing failover regularly validates the DR plan. Using a recovery plan orchestrates failover of multi-tier applications. Enabling replication for all critical VMs ensures protection. Option B is wrong because using a single target region for all VMs can cause resource contention; multiple target regions may be needed. Option E is wrong because manual failover should be used only if automatic fails.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

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.

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.
