The correct choice is Elastic Database Jobs with a T-SQL script for weekly index rebuilds, scheduled to minimize resource contention. This solution works because Elastic Database Jobs execute T-SQL commands across multiple Azure SQL Databases in an elastic pool with built-in concurrency control, allowing you to stagger or throttle operations so they don’t overwhelm shared pool resources. On the DP-300 exam, this scenario tests your understanding of automation limitations in Azure SQL Database—specifically that SQL Agent is unavailable, making Elastic Database Jobs the only native scheduler for cross-database maintenance. A common trap is selecting automatic tuning, but that only handles index creation and drop, not rebuilds. Remember the key distinction: for automated index maintenance across an elastic pool, think “Jobs, not Agent.”
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 are responsible for automating database maintenance on multiple Azure SQL Databases in an elastic pool. You need to rebuild fragmented indexes weekly. The solution should minimize resource contention. What should you implement?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "minimum / minimize"
Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.
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 with a T-SQL script that rebuilds indexes, and schedule it weekly.
Option C is correct because Elastic Database Jobs can run T-SQL scripts across databases in a pool with concurrency control. Option A is wrong because SQL Agent is not available in Azure SQL Database. Option B is wrong because manual scripts are not automated. Option D is wrong because automatic tuning does not handle index rebuilds; it manages index creation/drop.
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.
✗
Enable automatic tuning and set 'INDEX_REBUILD' option.
Why it's wrong here
Automatic tuning does not rebuild indexes; it only creates/drops indexes based on recommendations.
✗
Create a SQL Agent job on each database to rebuild indexes during off-peak.
Why it's wrong here
SQL Agent is not available in Azure SQL Database.
✓
Use Elastic Database Jobs with a T-SQL script that rebuilds indexes, and schedule it weekly.
Why this is correct
Elastic Jobs are designed for this scenario and can be scheduled to run at low-usage times.
Clue confirmation
The clue word "minimum / minimize" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Write a PowerShell script that connects to each database sequentially and rebuilds indexes.
Why it's wrong here
While possible, it requires manual scheduling and does not leverage built-in automation.
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.
