Which logging host command meets these requirements: syslog server 10.10.10.1, use a reliable protocol, and avoid well-known TCP/UDP ports?

The command logging host 10.10.10.1 transport tcp port 1024 is correct because it specifies TCP as the transport protocol, which is reliable, and uses port 1024. TCP ensures reliable delivery of syslog messages, which is a key requirement. Port 1024 is a non-well-known port (ports 0-1023 are well-known), fulfilling the requirement to avoid them. The option logging host 10.10.10.1 transport udp port 1024 is incorrect because UDP is an unreliable protocol, meaning message delivery is not guaranteed. The option logging host 10.10.10.1 transport udp port 1023 is incorrect for the same reason (UDP is unreliable) and also because port 1023 is a well-known port. The option logging origin-id 10.10.10.1 is incorrect as it configures the origin ID for syslog messages, not the syslog host or its transport parameters.
