A solutions architect is tasked with defining the DNS strategy for an existing VPC configured with the 10.24.34.0/24 CIDR block and utilizing Amazon Route 53 Resolver for DNS services. The new requirements specify that DNS queries should utilize private hosted zones, and instances with public IP addresses must be assigned corresponding public hostnames. What configuration will ensure proper domain name resolution within the VPC?
A
Establish a private hosted zone, enable both the enableDnsSupport and enableDnsHostnames attributes for the VPC, and modify the VPC DHCP options set to specify domain-name-servers=10.24.34.2.
B
Set up a private hosted zone, link it to the VPC, enable both the enableDnsSupport and enableDnsHostnames attributes for the VPC, create a new VPC DHCP options set with domain-name-servers=AmazonProvidedDNS, and associate it with the VPC.
C
Disable the enableDnsSupport attribute for the VPC, enable the enableDnsHostnames attribute, create a new VPC DHCP options set with domain-name-servers=10.24.34.2, and associate it with the VPC.
D
Create a private hosted zone, link it to the VPC, enable the enableDnsSupport attribute for the VPC, disable the enableDnsHostnames attribute, and update the VPC DHCP options set to include domain-name-servers=AmazonProvidedDNS.
