The answer is to deploy the instance in the Business Critical tier with zone redundancy and configure a failover group to another region. The Business Critical tier with zone redundancy ensures zero data loss during planned maintenance and automatic failover within 30 seconds by synchronously replicating data across three availability zones within a single region, guaranteeing that committed transactions are never lost. To meet the regional disaster recovery requirements of a 5-minute RPO and 1-hour RTO, a failover group provides automated, asynchronous replication to a secondary region, enabling a coordinated failover that meets those specific recovery objectives. On the DP-300 exam, this question tests your ability to distinguish between intra-region high availability and cross-region disaster recovery, with a common trap being the assumption that active geo-replication is supported for Managed Instance—it is not, as failover groups are the only native DR option. Remember the mnemonic: "Zone for zero loss, group for geo recovery."
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.
You are designing a high availability and disaster recovery solution for an Azure SQL Managed Instance that hosts a mission-critical database. You need to ensure zero data loss during planned maintenance and automatic failover within 30 seconds. Additionally, you must protect against a regional outage with an RPO of 5 minutes and an RTO of 1 hour. Which TWO features should you implement? (Select two.)
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure a failover group to a secondary region.
Option A is correct because Business Critical tier with zone redundancy provides zero data loss and fast failover within a region. Option C is correct because a failover group to another region provides DR with RPO of 5 minutes and RTO of 1 hour. Option B is wrong because General Purpose tier does not support zone redundancy. Option D is wrong because default backup retention does not meet RPO/RTO. Option E is wrong because active geo-replication is not supported for Managed Instance.
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 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.

Variation 1. You need to ensure that an Azure SQL Managed Instance remains available in the event of a single availability zone failure in a region that supports availability zones. What should you configure?
easy
A.Configure a failover group to another region.
B.Deploy the instance in General Purpose tier with zone redundancy.
C.Use a Hyperscale tier instance with zone redundancy.
✓ D.Deploy the instance in Business Critical tier with zone-redundant configuration.
Why D: Option B is correct because zone-redundant deployment for Managed Instance is available in Business Critical tier. Option A is wrong because General Purpose does not support zone redundancy. Option C is wrong because failover groups are for regional disasters, not zonal failures. Option D is wrong because Hyperscale is not a tier for Managed Instance.
