- A
Keep the primary as General Purpose, create a readable secondary in the same region, and configure active geo-replication to a secondary in West Europe.
Why wrong: General Purpose cannot guarantee 5-second RPO.
- B
Upgrade the primary to Business Critical, configure a failover group with a readable secondary in West Europe using Business Critical, and use the listener endpoint for application connections.
Business Critical meets RPO, readable secondary serves read traffic, failover group provides automated failover with listener endpoint.
- C
Deploy a zone-redundant Business Critical database in East US and use auto-failover groups to a secondary in West Europe with General Purpose.
Why wrong: General Purpose secondary cannot meet the RPO; also no readable secondary for read traffic.
- D
Upgrade the primary database to Business Critical, create a readable secondary in the same region, and use geo-restore for DR.
Why wrong: Geo-restore cannot meet the RPO of 5 seconds and RTO of 1 hour.
DP-300 Practice Question: Plan and configure a high availability and disaster recovery environment
This DP-300 practice question tests your understanding of plan and configure a high availability and disaster recovery environment. 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.
You are the database administrator for a global e-commerce company that uses Azure SQL Database for its product catalog. The database is currently deployed in the East US region using the General Purpose service tier. The company is expanding to Europe and wants to improve disaster recovery posture. The new requirements are: RPO of 5 seconds, RTO of 1 hour, and the ability to serve read traffic from the secondary region during normal operations. The budget is limited, so you must minimize cost while meeting these requirements. The application connection strings can be updated to a listener endpoint. What should you recommend?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"minimum / minimize"Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Upgrade the primary to Business Critical, configure a failover group with a readable secondary in West Europe using Business Critical, and use the listener endpoint for application connections.
Option D is correct because it uses Business Critical in the primary region for low RPO and readable secondary in the secondary region for read traffic, while using a failover group for automated failover. Option A is wrong because General Purpose cannot meet 5-second RPO. Option B is wrong because a readable secondary in the same region doesn't serve read traffic from Europe. Option C is wrong because zone-redundancy doesn't protect regionally.
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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
