- A
Create an Elastic Database Job that runs a T-SQL script to rebuild and reorganize indexes based on fragmentation thresholds, scheduled via job schedule.
Elastic Database Jobs are the recommended service for automating T-SQL tasks across one or many Azure SQL databases, with built-in scheduling and retry.
- B
Configure SQL Agent on the Azure SQL Database logical server to run index maintenance jobs.
Why wrong: SQL Agent is not available in Azure SQL Database; it is only available in SQL Server on Azure VMs or Managed Instance.
- C
Use Azure Automation runbooks with the Invoke-Sqlcmd cmdlet to run index maintenance scripts on a schedule.
Why wrong: Azure Automation can work, but it requires more overhead for runbook development, module management, and doesn't natively integrate with Azure SQL schedules as cleanly as Elastic Jobs.
- D
Deploy an Azure Function with a timer trigger that connects to the database and runs index maintenance commands.
Why wrong: Azure Functions can perform this task but lack the built-in job scheduling, retry, and logging features provided by Elastic Database Jobs, making it less efficient.
Quick Answer
The answer is to create an Elastic Database Job that runs a T-SQL script to rebuild and reorganize indexes based on fragmentation thresholds, scheduled via job schedule. This is the most efficient approach because Elastic Database Jobs are purpose-built for automated index maintenance across Azure SQL Databases, offering native scheduling, built-in retry logic, and centralized monitoring—unlike Azure Automation runbooks, which require manual schedule maintenance and error handling. On the DP-300 exam, this scenario tests your ability to choose the right tool for recurring T-SQL operations against Azure SQL, often appearing as a trap where candidates mistakenly select Azure Automation for its familiarity, forgetting that Elastic Database Jobs are the optimized, managed solution for index maintenance schedules. A key memory tip: think “Jobs for jobs”—Elastic Database Jobs handle repetitive database tasks like index rebuilds and reorganizations, while Automation is better suited for broader infrastructure orchestration.
DP-300 Configure and manage automation of tasks Practice Question
This DP-300 practice question tests your understanding of configure and manage automation of tasks. 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 manage a critical Azure SQL Database that requires automated index maintenance. You need to ensure that index rebuilds only occur during low-usage periods defined in a schedule, while index reorganizations run more frequently. What is the most efficient way to implement this using Azure Automation?
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
Create an Elastic Database Job that runs a T-SQL script to rebuild and reorganize indexes based on fragmentation thresholds, scheduled via job schedule.
Azure Automation runbooks can execute T-SQL scripts, but they require maintaining a schedule and handling errors manually. Elastic Database Jobs are purpose-built for scheduling T-SQL against Azure SQL Databases, providing simple scheduling, retry logic, and built-in monitoring. Option A is correct. Option B is less efficient because it requires more manual setup. Option C is not designed for this. Option D lacks scheduling.
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.

Same concept, more angles
3 more ways this is tested on DP-300
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. You are managing an Azure SQL Database that requires automated index maintenance. You want to use a solution that minimizes administrative overhead and leverages built-in Azure capabilities. Which approach should you recommend?
medium- ✓ A.Enable automatic tuning for the database and configure the 'CREATE INDEX' and 'DROP INDEX' recommendations.
- B.Deploy a third-party maintenance solution and connect it to the Azure SQL Database.
- C.Create a custom PowerShell script and run it via Azure Automation Runbook on a schedule.
- D.Schedule a SQL Agent job to rebuild indexes using a T-SQL script.
Why A: Option C is correct because Azure SQL Database's automatic tuning can automatically create and drop indexes based on workload patterns, minimizing manual overhead. Option A is wrong because Elastic Database Jobs require custom scripting and are not fully automated. Option B is wrong because it still requires manual scheduling and maintenance. Option D is wrong because it is a third-party tool and not built-in.
Variation 2. A company uses Azure SQL Database and wants to automatically send an email notification when an index fragmentation exceeds 30% for any database. Which solution should they implement?
medium- A.Create an Azure Monitor alert based on fragmentation
- B.Use Elastic Database Jobs to check fragmentation and send email
- C.Configure SQL Agent job to send email
- ✓ D.Use Azure Automation runbook to query sys.dm_db_index_physical_stats and send email
Why D: Azure Automation runbooks can query fragmentation and send emails via SendGrid. Elastic Database Jobs can check fragmentation but cannot send emails directly. Azure Monitor alerts can trigger on metrics like DTU but not on index fragmentation. Azure Logic Apps can receive data but require custom setup.
Variation 3. A company uses Azure SQL Managed Instance and needs to automatically rebuild fragmented indexes weekly during low usage. They also need to update statistics. Which approach should they take?
hard- A.Use Elastic Database Jobs to run index maintenance
- ✓ B.Use Azure Automation runbook with Invoke-SqlCmd to run maintenance scripts
- C.Use Azure Logic Apps with SQL connector
- D.Create a SQL Agent job on the managed instance
Why B: Azure Automation runbooks can run maintenance scripts but require custom coding. SQL Agent is not available in managed instance. Elastic Database Jobs cannot be used with managed instance. Azure Logic Apps can trigger but are not ideal for long-running T-SQL. The correct approach is to use Azure Automation with PowerShell runbooks executing T-SQL.
