Exam 200-301 topic 1 question 843 discussion

they are intentionally spinning you with speech then give you the question nothing straight

but in answer B , lldp is not enabled globally.For lldp to function, 'lldp run' command must be issued in the global configuration mode and 'lldp transmit' and 'lldp receive' must be issued in the interface configuration mode.

B is correct

A is incorrect (there is no "lldp enable" command. To enable LLDP on an interface we use the two commands: "lldp transmit" & "LLDP receive") B is correct but it is missing "lldp run command." On cisco devices, LLDP is globally disabled by default and we need to enable it globally, before configuring its settings under a certain interface. Option B is the most Correct of the 4 Choices. C is incorrect (lldp run is a global config command; it is not configured under the interface settings) D is incorrect (CDP run is a global config command; it is not configured under the interface settings).

From my research, I couldn't find one source that uses "lldp enable" command and even if it's used it will be used per interface level. A & C are incorrect. D is wrong because cdp run command is a gloabal configuration command not per interface level and we need to use lldp since it's a multivendor scenario. B is correct

Unfortunately, it is the best of all the crappy answers provided. if lldp run or lldp enabled is run at the config level. it will enable lldp on all the ports. B is the best answers from all of them.

Answer is B. Can't be answer A since 'lldp enable' isn't a legitimate command.

B is correct because the commands "SW1(config-if)#lldp transmit - SW1(config-if)#lldp receive" enable LLDP directly on the specific interface, without needing the command "SW1(config)#lldp run" which would also work, as it enables LLDP on all interfaces. CDP is enabled on all interfaces with the command "(config)#cdp run" and we disable or enable it only on a specific interface with "(config-if)#cdp enable" or "(config-if)#no cdp enable" , but in LLDP the "lldp enable" command does not exist, because we have more options like defining "transmit" and "receive" on the interface, while CDP can only enable or disable a CDP interface with "cdp enable", that's why LLDP has more options. Correct me if I'm wrong on any point!

it doesn't say it's a cisco switch, it's a 3rd party vendor. so. The commands "lldp transmit" and "lldp receive" are used to enable or disable the transmission and reception of LLDP (Link Layer Discovery Protocol) packets on a network device. To effectively use these commands, the LLDP feature must be enabled on the device. The specific command to enable LLDP may vary depending on the operating system or platform. However, a common command is "lldp run" or "lldp enable" to globally enable LLDP on the device. So, to use "lldp transmit" and "lldp receive" commands, it is generally necessary to have "lldp run" or a similar command enabled on the device. This ensures that LLDP is actively running, allowing the device to transmit and receive LLDP packets and participate in the LLDP discovery process with neighboring devices.

https://www.comparitech.com/net-admin/cisco-discovery-protocol/#:~:text=Can%20CDP%20and%20LLDP%20coexist,to%20interoperate%20with%20other%20vendors. Can CDP and LLDP coexist? Yes. CDP and LLDP can coexist, or be used at the same time, especially if your network environment is made up of devices from different vendors. The majority of Cisco devices will also support LLDP, as this allows them to interoperate with other vendors. However, in those devices, LLDP is off by default. I think A is correct because LLDP will not work without "lldp run" command.

In "B" answer is missing "lldp run" command.... without that command lldp will not work

B should be correct. CDP is a Cisco’s Proprietary Layer 2 Neighbor Discovery Protocol; it should be disabled in the global configuration mode and would not work in a multivendor environment. LLDP is the vendor neutral, IEEE 802.1AB standard protocol for Layer 2 Neighbor Discovery that Cisco switches generally support. CDP is enabled by default on Cisco Switches and must be disabled globally. Answer B is correct.

can anyone confirm this?
