Question 6 of 953

Plan and configure a high availability and disaster recovery environment →hardMultiple SelectObjective-mapped

Quick Answer

The answer is to initiate a planned failover from the Azure portal or PowerShell, ensure the new primary has a readable secondary configured, and update the application connection string. A planned failover is the correct approach for planned failover geo-replication maintenance because it synchronizes all committed transactions before switching roles, guaranteeing zero data loss—unlike an unplanned failover which may sacrifice recent writes. On the DP-300 exam, this scenario tests your understanding of active geo-replication’s graceful role swap versus forced failover; a common trap is choosing “force failover with data loss” when the intent explicitly requires maintenance without data loss. Remember that a planned failover is always the safe, synchronous choice for maintenance windows, while forced failover is reserved for actual disasters. Memory tip: “Plan to sync, don’t force to lose”—planned failover syncs data first, forced failover skips sync and risks loss.

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 uses Azure SQL Database with active geo-replication for disaster recovery. The primary database is in the West Europe region. You need to perform a planned failover to the secondary in North Europe for a maintenance window. Which THREE actions should you take? (Choose three.)

A
Initiate a forced failover to ensure the fastest switchover.
Why wrong: Forced failover may cause data loss; planned failover is preferred for maintenance.
B
Manually seed the new secondary database after failover.
Why wrong: Seeding happens automatically when geo-replication is established.
C
After failover, verify that the new secondary (in West Europe) is configured as a readable secondary.
To restore DR capabilities, the former primary should be re-configured as a secondary.
D
Update the application connection strings to point to the new primary in North Europe.
Applications must connect to the new primary after failover.
E
Initiate a planned failover (no data loss) from the Azure portal or PowerShell.
Planned failover ensures no data loss during maintenance.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

After failover, verify that the new secondary (in West Europe) is configured as a readable secondary.

Options A, C, and D are correct. A planned failover ensures no data loss by synchronizing all transactions before switching. After failover, the new primary should have a readable secondary or geo-replication configured to maintain DR. Updating the connection string is necessary for applications. Option B is wrong because you want to avoid data loss. Option E is wrong because seeding is automatic.

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.
