The answer is sys.dm_db_resource_stats, which is the correct dynamic management view to query when you need to identify high resource consuming queries in Azure SQL Database. This DMV returns per-minute resource consumption data, including CPU, I/O, and log write percentages, directly reflecting DTU usage at the database level. On the Microsoft Azure Database Administrator Associate DP-300 exam, this question tests your understanding of Azure-specific DMVs versus their SQL Server counterparts—a common trap is choosing sys.dm_exec_query_stats, which is unavailable in Azure SQL Database, or sys.dm_exec_requests, which only shows currently running queries. The key distinction is that sys.dm_db_resource_stats provides historical, aggregated resource metrics, making it ideal for pinpointing periods of high DTU consumption and correlating them with specific queries. For a memory tip, think “DB Resource Stats = Database Resource Stats” to remember it’s the database-level view for DTU analysis, not the server-level or execution-level views.
DP-300 Practice Question: Monitor, configure, and optimize database resources
This DP-300 practice question tests your understanding of monitor, configure, and optimize database resources. 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 an Azure SQL Database that is experiencing higher than expected DTU consumption. You need to identify which queries are consuming the most resources. Which dynamic management view should you query?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Query sys.dm_db_resource_stats
sys.dm_db_resource_stats provides per-minute resource consumption data for the database. Option A is wrong because sys.dm_exec_query_stats is not available in Azure SQL Database (it is for SQL Server). Option C is wrong because sys.dm_os_wait_stats is for server-level waits. Option D is wrong because sys.dm_exec_requests shows only currently executing requests.
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.
✗
Query sys.dm_exec_requests
Why it's wrong here
sys.dm_exec_requests shows only currently executing requests, not historical resource consumption.
✗
Query sys.dm_os_wait_stats
Why it's wrong here
sys.dm_os_wait_stats is for server-level wait statistics, not per-query resource usage.
✗
Query sys.dm_exec_query_stats
Why it's wrong here
sys.dm_exec_query_stats is not available in Azure SQL Database.
✓
Query sys.dm_db_resource_stats
Why this is correct
sys.dm_db_resource_stats provides per-minute resource usage data for the database.

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.

Variation 1. Your Azure SQL Database is experiencing high CPU usage. You suspect a specific query is causing the issue. You have enabled Query Store. How can you identify the query that has consumed the most cumulative CPU time over the last hour?
medium
A.Use sys.dm_exec_query_stats to sort by total_worker_time.
✓ B.Use the Query Store Top Resource Consuming Queries report and filter by the last hour.
C.Use sys.dm_exec_requests to find queries with high CPU.
D.Use the Query Store Regressed Queries report.
Why B: Option D is correct because the Top Resource Consuming Queries report in Query Store shows cumulative CPU time, duration, and other metrics, allowing easy identification. Option A is wrong because sys.dm_exec_query_stats shows current cached plans but not cumulative over a specific time window. Option B is wrong because the Regressed Queries report shows plan changes, not CPU consumption. Option C is wrong because sys.dm_exec_requests shows currently running queries, not historical cumulative use.
