An administrator has enabled a VPC DNS forwarder that points to 10.20.0.10 in a shared services VPC. Name resolution from the web segment fails whenever the core link is unavailable.

Which configuration would keep DNS available during the core outage?

Explanation

A private Transit Gateway can provide an alternate private Layer 3 routing path between the web segment and the shared-services VPC hosting the DNS forwarder. Transit Gateway is a network transit hub for interconnecting VPCs, and its DNS support can be enabled for attached VPCs. MTU, source NAT, and DHCP do not create a resilient path to the remote DNS forwarder.
