DP-300 Practice Question: Monitor, configure, and optimize database resources
Which TWO metrics in Azure SQL Database's Intelligent Insights can indicate a performance degradation due to increased resource consumption? (Choose two.)
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
✓
Increased query duration.
Options A and D are correct. In Azure SQL Database's Intelligent Insights, increased query duration and high DTU consumption are key metrics that indicate performance degradation due to increased resource consumption. Increased query duration suggests that queries are taking longer, often due to resource contention. High DTU consumption reflects high usage of CPU, memory, and I/O, which can degrade performance. Option B (high number of deadlocks) indicates concurrency issues but does not directly measure resource consumption. Option C (increased transaction log usage) is related to write activity, not a primary performance metric in Intelligent Insights. Option E (failed authentication attempts) is a security metric, unrelated to resource consumption.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Increased query duration.
Why this is correct
Longer query duration indicates performance degradation.
- ✗
High number of deadlocks.
Why it's wrong here
Deadlocks are concurrency issues, not directly resource consumption.
- ✗
Increased transaction log usage.
Why it's wrong here
Log usage is not a direct performance metric in Intelligent Insights.
- ✓
High DTU consumption.
Why this is correct
DTU consumption directly indicates resource usage.
- ✗
Failed authentication attempts.
Why it's wrong here
This is a security metric.
