AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

An organization has a Direct Connect link between its on-premises data center and an AWS VPC. EC2 instances in the VPC must resolve host names in the on-premises corp.example.com domain by using the existing on-premises DNS server at 10.0.0.2. The operations team wants a scalable solution that requires no per-instance configuration changes or manual record maintenance. According to AWS best practices, which action will meet these requirements?

  • Enable DNS resolution and DNS hostnames in the VPC; the Amazon-provided DNS server will automatically forward corp.example.com queries across Direct Connect.

  • Create a private hosted zone for corp.example.com in Route 53 and manually populate A and CNAME records for all on-premises hosts.

  • Update the VPC's DHCP options set to hand out 10.0.0.2 as the primary DNS server, then restart networking on every EC2 instance.

  • Create a Route 53 Resolver outbound endpoint in two private subnets. Add a rule that forwards queries for corp.example.com to 10.0.0.2 and associate the rule with the VPC.
