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. 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 are designing a disaster recovery strategy for an Azure SQL Database in the West US region. The database is used by a mission-critical application with an RPO of 5 seconds and an RTO of 30 seconds. Which deployment option should you choose?

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

Use active geo-replication with a readable secondary in another Azure region

Active geo-replication provides an asynchronous replica in a secondary region with an RPO of up to 5 seconds and supports manual failover with an RTO of approximately 30 seconds, meeting the strict RPO and RTO requirements for disaster recovery. Zone-redundant configuration (Option C) offers high availability within a single region but does not protect against regional outages, so it is not a disaster recovery solution. Failover groups (Option B and D) have an RTO of about 1 hour, exceeding the 30-second requirement. Therefore, Option A is correct.

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.

  • Use active geo-replication with a readable secondary in another Azure region

    Why this is correct

    Correct. Active geo-replication offers an RPO of up to 5 seconds and an RTO of around 30 seconds, matching the requirements precisely. It creates a readable secondary in a different Azure region for disaster recovery.

  • Use a failover group with a secondary in a paired region

    Why it's wrong here

    Incorrect. Failover groups provide an RPO of about 5 seconds but an RTO of approximately 1 hour, which exceeds the 30-second RTO. Also, they require a secondary in a paired region and do not guarantee the low RTO needed.

  • Deploy the database with zone-redundant configuration in the primary region

    Why it's wrong here

    Incorrect. Zone-redundant configuration provides high availability within a single region by replicating across availability zones. It does not provide disaster recovery across regions, so it cannot protect against a regional outage.

  • Deploy the database with an auto-failover group to a secondary region

    Why it's wrong here

    Incorrect. An auto-failover group is essentially a failover group with automatic failover policies. The RTO is still around 1 hour, not meeting the 30-second requirement.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Candidates often mistake high availability within a region for disaster recovery. While zone redundancy protects against zonal failures, it does not provide cross-region resilience. For true disaster recovery with very low RPO/RTO, active geo-replication is the appropriate choice.

Detailed technical explanation

How to think about this question

Zone-redundant configuration uses Azure SQL Database's built-in high availability model, which leverages Always On Availability Groups across three zones within a region, ensuring synchronous data replication with zero data loss (RPO=0) and automatic failover within seconds. This is distinct from geo-replication, which uses asynchronous replication and introduces a replication lag that can exceed 5 seconds under load, making it unsuitable for the given RPO/RTO targets. In a real-world scenario, if the primary region experiences a full outage, zone-redundant configuration would still fail because all zones are in the same region, but the question's RPO/RTO requirements are so low that only intra-region zone redundancy can satisfy them.

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.

TExam Day Tips

  • 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

An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
