A network engineer must create a diagram of a multivendor network. Which command must be configured on the Cisco devices so that the topology of the network is allowed to be mapped?
Click on the arrows to vote for the correct answer
A. B. C. D.A
The command that should be configured on the Cisco devices to enable mapping of the topology of a multivendor network is lldp run. Therefore, the correct answer is A.
LLDP (Link Layer Discovery Protocol) is a standard protocol that allows devices to share information about their identities, capabilities, and neighbors on a network. It is a vendor-neutral protocol, which means it can be used to discover and map the topology of a multivendor network. When the lldp run command is configured on a Cisco device, it enables the device to send and receive LLDP packets.
The other answer choices are:
B. cdp run: This command enables the Cisco Discovery Protocol (CDP), which is a Cisco proprietary protocol used to discover and map Cisco devices on a network. While CDP can be useful in mapping Cisco-specific devices, it may not be as effective in a multivendor environment.
C. cdp enable: This command enables CDP on a specific interface of a Cisco device. Similar to the previous answer, while CDP can be useful in mapping Cisco-specific devices, it may not be as effective in a multivendor environment.
D. flow-sampler-map topology: This command is not relevant to mapping the topology of a network. It is used to configure a flow sampler to monitor traffic patterns in a network.
Therefore, the correct answer is A.
