Question 18 of 100 | ← Chapter 1

A SysOps administrator is investigating issues on an Amazon RDS for MariaDB DB instance. The SysOps administrator wants to display the database load categorized by detailed wait events. How can the SysOps administrator accomplish this goal?

• A. Create an Amazon CloudWatch dashboard.
• B. Enable Amazon RDS Performance Insights. ✓
• C. Enable and configure Enhanced Monitoring.
• D. Review the database logs in Amazon CloudWatch Logs.

Correct Answer: B. Enable Amazon RDS Performance Insights.

Explanation

该题考查Amazon RDS性能监控的核心服务区分。Performance Insights专为数据库负载分析设计，通过可视化SQL执行等待事件定位性能瓶颈，可直接展示按等待事件分类的负载详情；而CloudWatch侧重基础资源指标，增强监控聚焦操作系统级数据，数据库日志则记录运行状态而非结构化性能分析。正确答案为B。
