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. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.

Exhibit

Refer to the exhibit.

```json
{
  "properties": {
    "createMode": "Recovery",
    "sourceDatabaseId": "/subscriptions/.../resourceGroups/rg1/providers/Microsoft.Sql/servers/server1/databases/db1",
    "requestedServiceObjectiveName": "GP_Gen5_2",
    "elasticPoolId": null,
    "location": "eastus"
  }
}
```

You are reviewing an ARM template for creating a new Azure SQL Database. The template uses the above JSON to create a database named 'db2' from 'db1'. The source database 'db1' is currently in a failed state due to a storage issue. What will be the result of deploying this template?

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

✓

The deployment will fail because db1 is not in a recoverable state.

The ARM template creates a new database by copying from a source database. Azure SQL Database requires the source database to be in an online and healthy state to perform a copy operation. Since db1 is in a failed state due to a storage issue, it is not accessible for copying, so the deployment will fail.

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.

  • ✓

    The deployment will fail because db1 is not in a recoverable state.

    Why this is correct

    Recovery mode requires the source to be dropped or after geo-failover.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    It will create an empty database because the source is not accessible.

    Why it's wrong here

    Empty database creation would require createMode 'Default'.

  • ✗

    It will delete db1 and create db2 as a replacement.

    Why it's wrong here

    Recovery mode does not delete the source.

  • ✗

    It will create a new database by recovering db1 to its last known good state.

    Why it's wrong here

    Recovery mode works only for dropped databases or after geo-failover, not for failed state databases.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates may confuse a database copy with a point-in-time restore, assuming that a failed source can still be used to create a new database via recovery, but the copy operation explicitly requires an online source.

Detailed technical explanation

How to think about this question

The database copy operation in Azure SQL Database uses the CREATE DATABASE AS COPY OF statement, which requires the source database to be in an ONLINE state. If the source is in a failed state, the copy cannot initiate because the underlying storage is unavailable. In contrast, a point-in-time restore (PITR) can recover a database to a specific point in time even if the source is offline, but that requires a different resource type (Microsoft.Sql/servers/databases with restorePointInTime property) in the ARM template.

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

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.
