CCNA: Cisco Certified Network Associate — Question 886

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

Answer options

• A. SNMP
• B. DNS lookup
• C. syslog
• D. NTP

Correct answer: B

Explanation

The correct answer is B, as DNS lookup translates the device name into an IP address, allowing the Telnet connection to be established. A (SNMP) is used for network management and monitoring, C (syslog) is for logging system messages, and D (NTP) is for time synchronization, none of which facilitate the Telnet connection directly.
