A network account owns a Transit Gateway and a Route 53 Resolver rule set that parks, courts, and public-works accounts must use without recreating those resources. How should those networking assets be shared?
Select an answer to reveal the explanation.
Short Explanation
Picture one city highway interchange and one DNS rulebook owned by Public Works Networking — departments get an on-ramp, not their own cloverleaf. AWS RAM is how you share that Transit Gateway and Resolver rule set into workload accounts cleanly.
Full Explanation
AWS RAM is the intended multi-account sharing mechanism for resources such as Transit Gateway and Route 53 Resolver rules. Centralizing ownership in a network account and sharing to consumers reduces sprawl and keeps routing and DNS policy consistent. Duplicating Transit Gateways or manual rule copy-paste increases operational drift. Hosting critical shared networking in a sandbox or via ad-hoc peering is neither a governance nor a scalable connectivity pattern.
