• D. 10.111.4.1

Correct answer: A

Explanation

The correct DNS server address for a VPC is typically the first usable IP address in the VPC CIDR block. In this case, 10.111.0.2 is the first usable IP in the range of 10.111.0.0/16. The other options either fall within the subnet range or are not the first usable IP in the VPC range.
