A Direct Connect circuit is up and BGP is established, but one application prefix is unreachable. Which checks are most useful next? Select 2 answers.

1. Check advertised and received prefixes, route filters, and the selected forwarding route.
2. Check the return route and any more-specific routes that may override the intended path.
3. Replace the circuit solely because its physical state is available.
4. Delete every BGP route before collecting the current routing evidence.
5. Increase the application connection timeout without examining route advertisements.
