What is the purpose of an outbound Route 53 Resolver endpoint?

To forward DNS queries from VPCs to on-premises DNS servers

To receive DNS queries from on-premises DNS servers

To provide DNS resolution for public domains

In AWS, how can split-horizon DNS be implemented for a domain used both internally and externally?

By using a public hosted zone and a private hosted zone with the same domain name

By using a single hosted zone with multiple records

By using Route 53 Resolver endpoints

In a multi-account AWS environment, what is a common pattern for implementing centralized DNS management?

Create a private hosted zone in each account and duplicate all DNS records

Use a shared services account to host private hosted zones and associate them with VPCs in other accounts

Use public hosted zones for all internal DNS resolution

Configure each VPC with its own DNS server

A company has a VPC with an outbound Resolver endpoint. They need to resolve names in the domain corp.example.com using on-premises DNS servers at 192.168.1.10 and 192.168.1.11. They also need to resolve names in the domain aws.example.com using a DNS server in a peered VPC at 10.0.0.53. Which configuration should you implement?

Create a forwarding rule for corp.example.com and rely on the VPC's default DNS resolution for aws.example.com.

Create a private hosted zone for aws.example.com and a forwarding rule for corp.example.com.

Create a single forwarding rule for example.com that targets both the on-premises servers and the peered VPC server.

Create two forwarding rules: one for corp.example.com targeting the on-premises servers, and one for aws.example.com targeting the peered VPC server.

In Route 53 Resolver, what is a conditional forwarding rule used for?

To block DNS queries for a specific domain

To forward DNS queries for a specific domain to a designated DNS server

To create a private hosted zone for a specific domain

To cache DNS responses for a specific domain
