問題文
A client cannot reach a service on a server. You confirm that the client can resolve the server's name to the correct address. Which check should come next?
選択肢
- Rejoin the server to the domain to refresh its computer account.
- Restart the client computer to clear its network stack.
- Recreate the host record for the server in the forward lookup zone, because a record that resolves to the right address can still carry a stale entry elsewhere in the zone that the client falls back to when the first attempt does not answer.
- Verify that the service is listening on the expected port on the server and that the port is permitted through the firewall along the path.
