Exam N10-008 topic 1 question 215 discussion

This seems correct per: https://www.cisco.com/c/en/us/td/docs/optical/cpt/r9_3/command/reference/cpt93_cr/cpt93_cr_chapter_01000.html

A. show interface Link Aggregation Control Protocol (LACP) is a standard protocol used to bundle multiple physical links together to form a single logical link. To determine whether an LACP bundle is fully operational, the technician will likely use the "show interface" command. This command is used to display the status of network interfaces on a device, such as a switch or router. When the technician runs the "show interface" command, the output will include the status of the LACP bundle, such as whether it is up or down and whether all of the physical links in the bundle are active and working properly. The technician can also use the command "show interfaces ethernet [interface-number] lacp" to display the LACP information for a specific bundle.

Show interface command displays information about the interfaces on a switch, including their operational status, utilization, error statistics, and other key performance metrics. Show config isn't directly asking the router detailed information, but checks the client's port connections that run through your firewall.

Show Etherchannel :)

GPT picks (A) show interface: "The "show interface" command provides detailed information about the status and configuration of network interfaces on a device, including LACP bundles. By using this command, the technician can view the operational status, speed, duplex mode, VLAN information, and any errors or counters related to the LACP bundle. LACP is used for link aggregation, often referred to as "EtherChannel" or "port-channel" in Cisco terminology. It allows multiple physical links to be combined into a single logical link to increase bandwidth and redundancy. The other options are less likely to provide information specifically about the operational status of an LACP bundle: (B) show config: This command typically shows the current configuration settings on the device but may not provide real-time operational status information. (C) show route: This command displays the routing table and routing information but doesn't directly relate to LACP bundle status. (D) show arp: This command shows the Address Resolution Protocol (ARP) table, which maps IP addresses to MAC addresses, but it's not directly related to LACP bundle status."

Show config will not show the status

LACP, a subcomponent of IEEE 802.3ad, provides additional functionality for link aggregation groups (LAGs). Use the link aggregation feature to aggregate one or more Ethernet interfaces to form a logical point-to-point link, known as a LAG, virtual link, or bundle.
