The answer is to enable zone redundancy on the Hyperscale database. This configuration is correct because Hyperscale’s architecture uses multiple page servers and log service replicas, and enabling zone redundancy automatically distributes these compute and storage replicas across different Azure availability zones, ensuring the database remains available during a single zone failure without any manual intervention. On the Microsoft Azure Database Administrator Associate DP-300 exam, this question tests your understanding of high-availability features specific to the Hyperscale service tier, where a common trap is confusing zone redundancy with active geo-replication or failover groups—geo-replication handles regional disasters, not zone failures, and failover groups apply to managed instances, not Hyperscale databases. A useful memory tip is to think of zone redundancy as “local safety within one region” versus geo-replication as “regional escape.”
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.
You have an Azure SQL Database in the Hyperscale service tier. You need to ensure that the database remains available during a single Azure zone failure. The solution must not require manual intervention. What should you configure?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable zone redundancy on the Hyperscale database.
Option A is correct because Hyperscale supports zone redundancy, which automatically places replicas in different zones. Option B (active geo-replication) is for DR, not zone failure. Option C (failover group) is for managed instances. Option D (auto-failover group) is for managed instances, not Hyperscale databases.
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.
✗
Create a failover group with a secondary in a different zone.
Why it's wrong here
Failover groups are for managed instances, not Hyperscale.
✓
Enable zone redundancy on the Hyperscale database.
Why this is correct
Hyperscale zone redundancy provides automatic recovery from zone failure.

Read the scenario before looking for a memorised answer.
✗
Configure active geo-replication to a secondary server in a different zone.
Why it's wrong here
Active geo-replication is for cross-region DR, not zone failure.
✗
Configure an auto-failover group with a secondary in a different zone.
Why it's wrong here
Auto-failover groups are for managed instances.
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.
