A company is transitioning its mobile banking applications to operate on Amazon EC2 instances within a VPC. These applications require DNS resolution to an on-premises Active Directory domain, which is accessible via an AWS Direct Connect link. What is the most efficient solution with minimal administrative effort to facilitate this DNS resolution?
A
Deploy a pair of EC2 instances in two different Availability Zones within the VPC to act as caching DNS servers for resolving queries from the application servers.
B
Set up an Amazon Route 53 private hosted zone and configure it with NS records directing to the on-premises DNS servers.
C
Utilize Amazon Route 53 Resolver to establish DNS endpoints and set up conditional forwarding rules to manage DNS namespace resolution between the on-premises data center and the VPC.
D
Launch a new Active Directory domain controller in the VPC and establish a bidirectional trust relationship with the existing on-premises Active Directory domain.
