What facilitates a Telnet connection between devices by entering the device name?

The correct answer is B. DNS lookup. DNS lookup facilitates a Telnet connection by device name by translating the human-readable hostname into its corresponding IP address. This IP address is then used to establish the network connection.

Why each option

DNS lookup facilitates a Telnet connection by device name by translating the human-readable hostname into its corresponding IP address. This IP address is then used to establish the network connection.

ASNMP

SNMP (Simple Network Management Protocol) is used for network device monitoring and management, not for resolving hostnames to IP addresses for connection establishment.

BDNS lookupCorrect

When a user attempts to connect to a network device using its device name (hostname) via Telnet, the system first performs a Domain Name System (DNS) lookup. DNS is responsible for resolving the human-readable hostname into its numerical IP address, which is essential for establishing the underlying network connection.

Csyslog

Syslog is a protocol used for collecting and centralizing log messages from network devices, not for hostname resolution.

DNTP

NTP (Network Time Protocol) is used to synchronize the clocks of network devices, and it has no role in translating device names to IP addresses for connectivity.
