NEW QUESTION 63
An ecommerce website running on AWS uses an Amazon RDS for MySQL DB instance with General Purpose SSD storage. The developers chose an appropriate instance type based on demand, and configured 100 GB of storage with a sufficient amount of free space.
The website was running smoothly for a few weeks until a marketing campaign launched. On the second day of the campaign, users reported long wait times and time outs. Amazon CloudWatch metrics indicated that both reads and writes to the DB instance were experiencing long response times. The CloudWatch metrics show 40% to 50% CPU and memory utilization, and sufficient free storage space is still available. The application server logs show no evidence of database connectivity issues.
What could be the root cause of the issue with the marketing campaign?
- A. It exhausted the network bandwidth available to the RDS for MySQL DB instance.
- B. It exhausted the maximum number of allowed connections to the database instance.
- C. It caused the data in the tables to change frequently, requiring indexes to be rebuilt to optimize queries.

A user has created a VPC with a public subnet. The user has terminated all the instances which are part of the subnet.
Which of the below mentioned statements is true with respect to this scenario?
- A. The subnet to which the instances were launched with will be deleted
- B. When the user launches a new instance it cannot use the same subnet
- C. The user cannot delete the VPC since the subnet is not deleted
- D. Secondary network interfaces attached to the terminated instances may persist.
Answer: D
Explanation:
Explanation
A Virtual Private Cloud (VPC) is a virtual network dedicated to the user's AWS account. A user can create a subnet with VPC and launch instances inside that subnet. When an instance is launched it will have a network interface attached with it. The user cannot delete the subnet until he terminates the instance and deletes the network interface. By default, network interfaces that are automatically created and attached to instances using the console are set to terminate when the instance terminates. However, network interfaces created using the command line interface aren't set to terminate when the instance terminates.
