Question 171

A company is about to migrate an application from its on-premises data center to AWS. As part of the planning process, the following requirements involving DNS have been identified.

On-premises systems must be able to resolve the entries in an Amazon Route 53 private hosted zone.

Amazon EC2 instances running in the organization's VPC must be able to resolve the DNS names of on-premises systems The organization's VPC uses the CIDR block 172.16.0.0/16. Assuming that there is no DNS namespace overlap, how can these requirements be met?

Change the DHCP options set for the VPC to use both the Amazon-provided DNS server and the on-premises DNS systems. Configure the on-premises DNS systems with a stub-zone, delegating the name server 172.16.0.2 asauthoritative for the Route 53 private hosted zone.

Which two actions should you take to fix this problem? (Choose two.)

Use BGP AS prepend attribute to prepend additional AS numbers while advertising routers from R1 to VGW.

Use BGP local preference attribute to assign R1 to a lower local preference number than R2.
