CCNA: Cisco Certified Network Associate — Question 91

An engineer needs to configure LLDP to send the port description type length value (TLV). Which command sequence must be implemented?

Answer options

• A. switch(config-if)#lldp port-description
• B. switch#lldp port-description
• C. switch(config-line)#lldp port-description
• D. switch(config)#lldp port-description

Correct answer: A

Explanation

The correct answer is A because the command 'switch(config-if)#lldp port-description' is used in interface configuration mode, which is necessary for configuring LLDP on a specific interface. The other options are either in the wrong configuration mode or do not apply to the interface level, thus making them incorrect for this specific task.
