Oracle Database 12c: Performance Management and Tuning Sample Questions:
Question #1
In your database, the measured 99th percentile value is used as the maximum value. You set a warning threshold level of 110% of maximum trigger as an alert.
What is the outcome? (Choose the best answer.)
- A. It generates an error because the warning threshold cannot exceed 100%.
- B. It generates an alert when an observed metric is 99% of the 99th percentile value as measured over the moving window baseline.
- C. It generates an error because the percentage of maximum threshold cannot be set with a significance-level threshold value.
- D. It generates an alert when an observed metric is 110% of the 99th percentile value as measured over the moving window baseline.
- E. It generates an alert when 1 in 100 observations for an observed metric exceeds the 99th percentile value as measured over the fixed baseline.
Correct Answer: A 🗳️
Question #2
Your database supports a mixed workload. In an application, multiple complex queries with functions and expressions are executing. You want to analyze the queries that are currently cached in the library cache to receive recommendations about the usage of indexes and materialized views.
What should you do to achieve this? (Choose the best answer.)
- A. Capture the workload in an STS and submit to SQL Tuning Advisor for recommendations.
- B. Create an STS for the queries cached in the library cache and submit it as an input to SQL Access Advisor.

- D. Create an STS for the queries cached in the library cache and submit it as an input to SQL Performance Analyzer.
Correct Answer: D 🗳️
Question #3

Which three factors will you investigate further to identify the cause of the performance degradation? (Choose three.)
