Topic #: 1
[All AWS Certified Advanced Networking - Specialty ANS-C01 Questions]

A company has a hybrid IT setup that includes services that run in an on-premises data center and in the AWS Cloud. The company is using AWS Direct Connect to connect its data center to AWS. The company is using one AWS Site-to-Site VPN connection as backup and requires a backup connectivity option to always be present. The company is transitioning to IPv6 by implementing dual-stack architectures.

Which combination of steps will transition the data center's connectivity to AWS in the LEAST amount of time? (Choose two.)

  • A. Create a new Site-to-Site VPN tunnel for the IPv6 traffic.
  • B. Create a new dual-stack Site-to-Site VPN connection between the data center and AWS. Provision routing. Delete the original Site-to-Site VPN connection.
  • C. Associate a new dual-stack public VIF with the Direct Connect connection. Migrate the Direct Connect traffic to the new VIF.
  • D. Add a new IPv6 peer in the existing VIF. Use the IPv6 address provided by Amazon on the peer router.
  • E. Send IPv6 traffic between the data center and AWS in a tunnel inside the existing IPv4 tunnels.

AD are correct since a new vpn is needed and a new IPv6 peer can be added to the existing vif BE are wrong - since you cannot add iPv6 to an existing s2s and a s2s cannot be dual stack (https://docs.aws.amazon.com/vpn/latest/s2svpn/ipv4-ipv6.html) C is good but not fulfil the least amount of time requirement

Not sure why people are saying A as A has only ipv6 and the requirement is for dual-stack. Need B for new dual-stack VPN + D for adding ipv6 to the existing DX vif.

• Option A: Creating a new Site-to-Site VPN tunnel for IPv6 traffic allows you to gradually transition your connectivity to AWS while still using the existing Direct Connect connection. • Option D: Adding an IPv6 peer to the existing VIF enables you to start sending IPv6 traffic over the existing connection, allowing you to test your dual-stack architecture without disrupting the existing connectivity.
