Topic 1 Question 135
2 つ選択A company deploys an internal website behind an Application Load Balancer (ALB) in a VPC. The VPC has a CIDR block of 172.31.0.0/16. The company creates a private hosted zone for the domain example.com for the website in Amazon Route 53. The company establishes an AWS Site-to-Site VPN connection between its office network and the VPC.
A network engineer needs to set up a DNS solution so that employees can visit the internal webpage by accessing a private domain URL (https://example.com) from the office network.
Which combination of steps will meet this requirement?
Create an alias record that points to the ALB in the Route 53 private hosted zone.
Create a CNAME record that points to the ALB internal domain in the Route 53 private hosted zone.
Create a Route 53 Resolver inbound endpoint. On the office DNS server, configure a conditional forwarder to forward the DNS queries to the Route 53 Resolver inbound endpoint.
Create a Route 53 Resolver outbound endpoint. On the office DNS server, configure a conditional forwarder to forward the DNS queries to the Route 53 Resolver outbound endpoint.
On the office DNS server, configure a conditional forwarder for the private domain to the VPC DNS at 172.31.0.2.

- 正解だと思う選択肢: AC
AC is correct - why would you select A & B ? makes no sense, Alias records are free for AWS resources, you would get charged for lookups for CNAME records.

The question doesn't mention any existence of on prem DNS server.
