Question 1 of 30

In a recent performance analysis of your Oracle Database 19c environment, you generated an AWR report that indicated a significant increase in the average wait time for disk I/O operations. After reviewing the report, you noticed that the \"Top Wait Events\" section highlighted \"db file sequential read\" as the primary contributor to the wait time. What would be the most effective initial step to address this performance issue based on the insights from the AWR report?

Investigate and optimize the SQL queries that are causing excessive single-block reads.

Increase the size of the database buffer cache to reduce physical I/O operations.

Review and adjust the database's I/O subsystem configuration for better throughput.

Analyze the AWR report for any recent changes in workload patterns that could have influenced performance.
