Optional concept notes
LACP
Negotiates compatible physical links into one logical channel.

LACP
The core idea stays the same. The surrounding objective changes the evidence, decision, or task the exam asks for.
Port-channel interface
Represents an EtherChannel bundle as one logical interface.
Member consistency
Requires compatible speed trunk and VLAN settings across bundled links.
Layer 3 EtherChannel
Bundles routed physical ports under one logical IP interface.
Complete one provider lesson, then answer four related questions. That is enough for today; more practice is optional.
Your lesson stays open here while the provider opens in another tab. Choose one source; the notes above are optional.
Practice the reasoning here
Write or inspect a small Cisco configuration, name the expected show-command evidence, and explain how a frame or packet crosses it.
- State the expected result before changing or testing anything.
- Name the observation, command, log, or report that would confirm it.
- Explain why the closest alternative does not fit the same requirement.
Check the whole objective
This unlocks objective 2.4 for recall. The latest checkpoint needs 70% or higher; a lower result puts the lesson back near the front of your timeline.
