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 Managed Instance configured with a failover group across two regions. The primary region experiences a complete outage. You perform a manual failover to the secondary region. After the primary region is restored, you need to bring the original primary back into the failover group. What is the correct order of actions?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "primary"
Why it matters: Asks for the main purpose or function, not a secondary benefit. Eliminate answers that describe side-effects or partial functions.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Remove the original primary from the failover group and then add it back as a secondary.
Option C is correct because after a manual failover, the original primary becomes a secondary. To bring it back, you must first remove it from the failover group (if it's still listed), then re-add it as a secondary. Option A is wrong because automatic failover is not configured. Option B is wrong because you should not create a new instance. Option D is wrong because you should perform a planned failover to restore the original primary, but only after re-adding it.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Perform a planned failover back to the original primary region.

✗
Create a new SQL Managed Instance in the original region and add it to the failover group.
Why it's wrong here
Incorrect: The original instance still exists.
✗
Perform a forced failover to the original primary region.
Why it's wrong here
Incorrect: A forced failover is not needed; the original primary is already a secondary.

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.
