The correct answer is to set zoneRedundant to true and configure an auto-failover group with a secondary region. This is because Azure SQL Managed Instance does not support native zone redundancy for surviving a full regional outage; zoneRedundant only protects against failures within a single availability zone, not an entire region. To achieve regional outage protection without data loss, you must pair a primary instance with a secondary instance in a different Azure region using an auto-failover group, which provides continuous data replication and automatic failover. On the DP-300 exam, this question tests your understanding of the distinction between high availability within a region versus disaster recovery across regions—a common trap is assuming zoneRedundant alone covers regional failures. Remember the memory tip: “Zone for the zone, group for the globe”—zone redundancy handles local zone faults, while an auto-failover group handles global region outages.
DP-300 Plan and implement data platform resources Practice Question
This DP-300 practice question tests your understanding of plan and implement data platform resources. 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.
Refer to the exhibit. A DBA is creating an Azure SQL Managed Instance using the ARM template snippet shown. The DBA needs to ensure the instance can survive a regional outage without data loss. What change should be made to the template?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Set zoneRedundant to true and configure an auto-failover group with a secondary region
Option C is correct because Azure SQL Managed Instance does not natively support zone redundancy for regional outage protection; instead, it requires configuring an auto-failover group with a secondary instance in a paired region. Setting zoneRedundant to true alone only protects against zone failures within a single region, not a full regional outage. The auto-failover group ensures continuous replication and automatic failover to the secondary region, meeting the requirement of surviving a regional outage 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.
✗
Set collation to SQL_Latin1_General_CP1_CS_AS
Why it's wrong here
Collation change does not affect availability.
✗
Set zoneRedundant to true
Why it's wrong here
Zone redundancy protects against zonal failures, not regional outages.
✓
Set zoneRedundant to true and configure an auto-failover group with a secondary region
Why this is correct
Failover group with a secondary region provides regional disaster recovery.

Change storageAccountType to RA-GRS
Why it's wrong here
Storage account type does not affect instance availability.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse zone redundancy (which protects against datacenter failures within a region) with regional disaster recovery, and incorrectly assume that setting zoneRedundant to true is sufficient for surviving a regional outage, when in fact Azure SQL Managed Instance requires an auto-failover group with a secondary region for that purpose.
Detailed technical explanation
How to think about this question
Azure SQL Managed Instance uses Always On Availability Groups internally for high availability, but for disaster recovery across regions, you must explicitly create an auto-failover group that links the primary instance to a secondary instance in a different Azure region. The auto-failover group uses synchronous replication for the primary and asynchronous replication for the secondary, with a configurable grace period (default 1 hour) before automatic failover triggers. In a real-world scenario, if a regional outage occurs, the auto-failover group automatically promotes the secondary to primary, and applications can reconnect using the listener endpoint, ensuring zero data loss if the replication lag is within the grace period.

→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

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.
