Ultimate access to all questions.
A company hosts an internal website behind an Application Load Balancer (ALB) within a VPC that uses the CIDR block 172.31.0.0/16. They configure a private hosted zone for the domain example.com in Amazon Route 53 and establish an AWS Site-to-Site VPN connection between their office network and the VPC.
A network engineer must implement a DNS solution to enable employees to access the internal website via a private domain URL (https://example.com) from the office network.
Which two steps should be taken to fulfill this requirement?
A
Create an alias record that points to the ALB in the Route 53 private hosted zone.
B
Create a CNAME record that points to the ALB internal domain in the Route 53 private hosted zone.
C
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.
D
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.
E
On the office DNS server, configure a conditional forwarder for the private domain to the VPC DNS at 172.31.0.2.
