Optional concept notes
Global unicast
Identifies a globally routable IPv6 interface in 2000::/3.
Link-local
Supports same-link IPv6 communication using FE80::/10 addresses.
IPv6 multicast
Delivers one packet to subscribed interfaces using FF00::/8.
IPv6 anycast
Routes a shared unicast address to the nearest advertising 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 1.9 for recall. The latest checkpoint needs 70% or higher; a lower result puts the lesson back near the front of your timeline.
