AWS Certified SysOps Administrator – Associate — Question 80

A SysOps administrator is unable to launch Amazon EC2 instances into a VPC because there are no available private IPv4 addresses in the VPC.

Which combination of actions must the SysOps administrator take to launch the instances? (Choose two.)

Answer options

• A. Associate a secondary IPv4 CIDR block with the VPC.
• B. Associate a primary IPv6 CIDR block with the VPC.
• C. Create a new subnet for the VPC.
• D. Modify the CIDR block of the VPC.
• E. Modify the CIDR block of the subnet that is associated with the instances.

Correct answer: A, C

Explanation

The correct actions are A and C. By associating a secondary IPv4 CIDR block with the VPC, the administrator can increase the available private IPv4 addresses. Creating a new subnet also provides additional IP address space for the instances. Options B, D, and E do not directly resolve the issue of insufficient private IPv4 addresses for launching new EC2 instances.
