Does this command create a swarm service that only listens on port 53 using the UDP protocol? Solution: `docker service create -name dns-cache -p 53:53 -service udp dns-cache'

The command contains syntactical errors, specifically using `-name` instead of `--name` and an unrecognized `-service udp` flag, which means it will not execute successfully to create a UDP-only service.

The command uses `-name` instead of `--name` (a single dash is typically for single-letter options), which would cause an error. More critically, the `-service udp` flag is not a valid or recognized option for `docker service create` to specify the protocol for port mapping; the correct way is within the `-p` flag's syntax, like `53:53/udp`.
