Question 260
Correct Answer: B
The engineer needs to enable LLDP globally. LLDP (Link Layer Discovery Protocol) is a network discovery protocol used to advertise device information to directly connected devices. While LLDP can be enabled on specific interfaces, it will not work unless it is enabled globally on the device. This is essential when connecting to third-party network devices, as LLDP provides a standardized way to exchange information across different vendors' equipment.

such a dumb question...
CCNA_beast_69Option: A
It is correct. Big brain CCNA stuff right here lads.

I am so annoyed with Odom for claiming in OCG that you can have LLDP globally disabled and just configure LLDP on an interface, and then that interface will transmit and/or receive LLDP messages while LLDP is globally disabled on the device. Did anyone else notice that?!
KT_Yu
yup, that is wrong info
ZUMYOption: B
B is correct Link Layer Discovery Protocol (LLDP) is a layer 2 neighbor discovery protocol that allows devices to advertise device information to their directly connected peers/neighbors. It is best practice to enable LLDP globally to standardize network topology across all devices if you have a multi-vendor network.
AbdullahMohammad251Option: B
B is correct since LLDP is globally disabled by default. Check default setting for LLDP table, page 2/6 https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/6-x/system_management/configuration/guide/b_Cisco_Nexus_9000_Series_NX-OS_System_Management_Configuration_Guide/sm_lldp.pdf https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/6-x/system_management/configuration/guide/b_Cisco_Nexus_9000_Series_NX-OS_System_Management_Configuration_Guide/sm_lldp.pdf

Configure Link Layer Discovery Protocol (LLDP) Port Settings on a Switch through the Command Line Interface (CLI) - Cisco "... Disable LLDP on the Interface LLDP is disabled globally on the switch and on all supported interfaces. You must enable LLDP globally to allow a device to send LLDP packets. Once enabled, no changes are required at the interface level. ..."
PokoyoOption: B
Answer B LLDP-MED TLV support is enabled by default if LLDP is enabled globally and locally on a supported interface. Specific TLVs, however, can be enabled and suppressed. https://content.cisco.com/chapter.sjs?uri=/searchable/chapter/content/en/us/td/docs/ios-xml/ios/cether/configuration/15-mt/ce-15-mt-book/ce-lldp-multivend.html.xml

PE router (Provider Edge router): is a router between one network service provider's area and areas administered by other network providers. ISP (Internet Service Provider): is a company that provides access to the internet. ISPs can provide this access through multiple means, including dial-up, DSL, cable, wireless and fiber-optic connections.
