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. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Your company runs a mission-critical Azure SQL Database in the East US region. To meet an RPO of 5 seconds and an RTO of 30 minutes in the event of a regional outage, which deployment option should you choose?
Failover groups maintain a readable secondary and automatically fail over when primary becomes unavailable, meeting RPO of 5 seconds and RTO of 30 minutes.
B
Zone-redundant configuration
Why wrong: Zone-redundant configuration only protects within a region, not against regional outage.
C
Point-in-time restore
Why wrong: Restoring from backups takes hours and cannot meet the RPO/RTO requirements.
D
Active geo-replication with manual failover
Why wrong: Manual failover requires human intervention, which cannot guarantee 30-minute RTO.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Failover groups with auto-failover policy
Option A is correct because failover groups with auto-failover policy provide automatic failover with an RPO of 5 seconds (default) and RTO of 30 minutes. Active geo-replication requires manual failover, which does not meet the RTO. Zone-redundant configuration only protects within a region. Backup restore has much higher RPO/RTO.
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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
