Designing for Cisco Internetwork Solutions (DESGN, legacy) — Question 7

A network engineer is tasked to upgrade and expand a large existing production network. From the IOS CLI, what two protocols can be used to build a topology map of the existing network? (Choose two.)

Answer options

• A. SNMP
• B. IP SLA
• C. ICMP Echo
• D. LLDP
• E. Traceroute DE

Correct answer:

Explanation

The correct answers are A (SNMP) and D (LLDP) because both protocols can actively discover and map out network topology. SNMP can gather information from network devices, while LLDP enables devices to advertise their identity and capabilities. Options B (IP SLA) and C (ICMP Echo) do not provide the necessary topology mapping functionalities, and option E (Traceroute DE) is not a valid protocol for this purpose.
