Telnet: Telnet is a protocol used to establish remote connections to devices for administration. It directly communicates with devices on the network and is the best tool for identifying and accessing devices that support it on the subnet.

dig (A): Used for DNS queries, unrelated to Telnet.

runap (B): Not a recognized tool in this context.

tracert (C): Tracks the path to a host but does not establish direct connections.

BGP (Border Gateway Protocol) is used for routing data between different ISPs, making it essential for the functioning of the internet. Its primary use is for exchanging routing information between autonomous systems, especially different ISPs. Preventing loops within a LAN is handled by protocols like Spanning Tree Protocol (STP), while improving reconvergence times and sharing routes with a Layer 3 switch are functions of other protocols or internal mechanisms.
