Network Implementation

A company plans to move both its DNS registrar and DNS hosting to Amazon Route 53. Its website receives tens of thousands of visits daily, and its current DNS provider cannot handle the load. The company needs to migrate as quickly as possible but cannot accept any downtime.

Which solution satisfies these requirements?

  • A Transfer the domain name to Route 53. Create a Route 53 private hosted zone, and copy all the existing DNS records. Update the name servers on the domain to use the name servers that are specified in the newly created private hosted zone.
  • B Copy all DNS records from the existing DNS servers to a Route 53 private hosted zone. Update the name servers with the existing registrar to use the private hosted zone name servers. Transfer the domain name to Route 53. Ensure that all the changes have propagated.
  • C Transfer the domain name to Route 53. Create a Route 53 public hosted zone, and copy all the existing DNS records. Set the TTL value on each record to 1 second. Update the name servers on the domain to use the name servers that are specified in the newly created public hosted zone.
  • D Copy all DNS records from the existing DNS servers to a Route 53 public hosted zone. Update the name servers with the existing registrar to use the Route 53 name servers for the hosted zone. When the changes have propagated, perform a domain name transfer to Route 53.
Explanation

A public Route 53 hosted zone is required for Internet DNS resolution. Recreate the existing records in that zone, change the name servers at the current registrar to the Route 53 name servers, and allow the DNS change to propagate before transferring the domain registration. This keeps DNS service available throughout the registrar transfer; AWS specifically advises migrating DNS service before transferring registration when the current registrar might stop providing DNS service.
