Your company currently has a VPC defined as 10.0.0.0/16. Subnets are defined in this VPC, along with Instances created in the subnet. You need to ensure that resources in the VPC can resolve your on-premises DNS resources. How can you achieve this? Choose 2 answers from the options given below.

Answer options:

A.Create an EC2 Instance in your VPC which will act as the DNS server.
B.Configure DHCP Options for your VPC to point to the EC2 Instance.
C.Configure DHCP Options for your Subnet to point to the EC2 Instance.
D.Create a private hosted zone in Route53.

Answer – A and B
Here you can create your own EC2 Instance which will act as the DNS server. The VPC can then use the DHCP Options which points to this EC2 Instance as the DNS resolver.
Option C is incorrect because the DHCP options set is tagged with the VPC and not the subnet.
Option D is incorrect because the private hosted zone should be used with routing requests in the VPC.For more information on DNS in a VPC, please refer to the below URL
