Quiz covering Performance Optimization

What you'll be asked

  1. Which EBS volume type is considered the best general-purpose choice for most workloads that require a balance of price and performance?
  2. You have an application running on an EBS-backed EC2 instance that is experiencing high latency due to IOPS throttling. Your volume is a gp3 volume with 500 GB of storage. What is the most cost-effective way to increase IOPS without changing the volume type?
  3. A database application requires sub-millisecond latency and high sustained IOPS. Which EBS volume type is specifically designed for these high-performance, mission-critical workloads?
  4. An EC2 instance is utilizing an EBS volume, but you observe that the 'EBSByteBalance%' metric is consistently low. What does this indicate?
  5. You are running a high-performance database on a c6g.large instance with an io2 volume. Despite having provisioned 64,000 IOPS, the application is not achieving the expected performance. What is the most likely bottleneck?
