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. 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.
Which TWO of the following are benefits of using Azure SQL Database failover groups for high availability?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Automatic failover to a secondary region based on a grace period.
Options A and D are correct. Failover groups provide automatic failover (A) and read-only routing (D). Option B is wrong because failover groups do not provide load balancing within a region. Option C is wrong because failover groups do not replicate data synchronously across zones within a region (zone-redundancy does). Option E is wrong because failover groups do not provide backup redundancy.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Synchronous replication of data across availability zones.
Why it's wrong here
Zone-redundancy provides that, not failover groups.
✓
Automatic failover to a secondary region based on a grace period.
Why this is correct
Failover groups support automatic failover.

Read the scenario before looking for a memorised answer.
✓
Routing of read-only queries to the secondary region.
Why this is correct
Failover groups can route read-only queries to the secondary.
Related concept
Read the scenario before looking for a memorised answer.
✗
Load balancing read-write traffic across multiple replicas.
Why it's wrong here
Failover groups do not load balance; only one primary is used.
✗
Geo-redundant backup storage for disaster recovery.
Why it's wrong here
Backup storage redundancy is separate from failover groups.
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.
