A Company Hosts an Internal File-Sharing Application Running on Amazon

question 122

Multiple Choice

A company hosts an internal file-sharing application running on Amazon EC2 instances in VPC_A. This application is backed by an Amazon ElastiCache cluster, which is in VPC_B and peered with VPC_A. The company migrates its application instances from VPC_A to VPC_B. Logs indicate that the file-sharing application no longer can connect to the ElastiCache cluster. What should a database specialist do to resolve this issue?

• A) Create a second security group on the EC2 instances. Add an outbound rule to allow traffic from the ElastiCache cluster security group.
• B) Delete the ElastiCache security group. Add an interface VPC endpoint to enable the EC2 instances to connect to the ElastiCache cluster.
• C) Modify the ElastiCache security group by adding outbound rules that allow traffic to VPC_B's CIDR blocks from the ElastiCache cluster.
• D) Modify the ElastiCache security group by adding an inbound rule that allows traffic from the EC2 instances' security group to the ElastiCache cluster.
