- A
Use Elastic Database Jobs to run index maintenance scripts on all databases during off-peak hours, with parallel execution throttled.
Elastic Database Jobs can run T-SQL scripts across databases with scheduling and throttling.
- B
Use Azure Logic Apps with a SQL connector to run index maintenance on each database, with retry policies.
Why wrong: Logic Apps are not optimized for running T-SQL scripts across many databases.
- C
Create an Azure Automation Runbook that connects to each database and runs index maintenance sequentially.
Why wrong: Runbooks are less efficient for multiple databases and lack built-in throttling.
- D
Deploy Ola Hallengren’s IndexOptimize stored procedure in each database and schedule it via SQL Server Agent.
Why wrong: SQL Server Agent in Managed Instance is available but not designed for cross-database scheduling.
Quick Answer
The answer is to use Elastic Database Jobs to run index maintenance scripts on all databases during off-peak hours, with parallel execution throttled. This approach is correct because Elastic Database Jobs are purpose-built for orchestrating T-SQL scripts across multiple Azure SQL Managed Instance databases, offering configurable schedules and built-in throttling to minimize performance impact during business hours—critical for an OLTP workload. On the Microsoft Azure Database Administrator Associate DP-300 exam, this scenario tests your understanding of automated index maintenance without downtime, often trapping candidates who choose Ola Hallengren scripts alone (which lack a native scheduler) or Azure Automation Runbooks (which require complex multi-database setup). The key distinction is that Elastic Database Jobs provide both the scheduling and the throttling mechanism natively, making them the most efficient, low-impact solution. Memory tip: think “Jobs throttle jobs”—Elastic Database Jobs handle both the orchestration and the performance guardrails.
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.
Your company uses Azure SQL Managed Instance for a critical OLTP workload. You need to automate index maintenance for all databases in the instance without downtime. The solution must minimize performance impact during business hours. Which approach should you use?

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 Elastic Database Jobs to run index maintenance scripts on all databases during off-peak hours, with parallel execution throttled.
Option A is correct because Elastic Database Jobs can run index maintenance scripts across all databases with configurable schedules and throttling. Option B is wrong because Azure Automation Runbooks can be used but require more setup for multi-database execution and may not have built-in throttling. Option C is wrong because Ola Hallengren scripts are a best practice, but they need a scheduling mechanism; Elastic Database Jobs provide that. Option D is wrong because Azure Logic Apps are not designed for running T-SQL scripts across multiple databases.
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.
