DP-300 Practice Question: Plan and configure high availability and disaster recovery
This DP-300 practice question tests your understanding of plan and configure high availability and disaster recovery. 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.
Network Topology
Refer to the exhibit. An administrator wants to ensure that during a regional outage, the failover group automatically fails over without data loss if possible. What is the current configuration gap?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The backup storage redundancy is Local, which does not provide geo-redundancy for backups.
Automatic failover with data loss grace period is set to 60 minutes. The backup redundancy is Local, which means backups are stored only in the primary region. If a regional disaster occurs, backups might be lost. Geo-redundant backups would be needed to recover in the secondary region without data loss.
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.
✗
The failover policy is set to Automatic, but the grace period is too long.
Why it's wrong here
Grace period is acceptable; the issue is backup redundancy.
✓
The backup storage redundancy is Local, which does not provide geo-redundancy for backups.
Why this is correct
Geo-redundant backup storage (GRS) is needed to protect backups across regions.

Read the scenario before looking for a memorised answer.
✗
The secondary managed instance mi2 is in the same region as the primary.
Why it's wrong here
Secondary is in westus, primary in eastus; different regions.
✗
The read-only endpoint failover policy is Disabled, which prevents read-only traffic after failover.
Why it's wrong here
Read-only failover policy is not required for automatic failover.
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.
