Concept notes
RSA host key
Lets an SSH client authenticate the network device server.
IOS domain name
Supports RSA key generation when combined with a hostname.
transport input ssh
Restricts VTY inbound sessions to the SSH protocol.
login local
Authenticates a VTY session against configured local usernames.
Review the concept notes, then answer four related questions. That is enough for today; more practice is optional.
No setup required
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.
Your next milestone
Check the whole objective
This unlocks objective 4.8 for recall. The latest checkpoint needs 70% or higher; a lower result puts the lesson back near the front of your timeline.
One lesson at a time.Your block checks prepare you for this milestone. A score of 70% or higher advances the course; finishing a practice session completes your daily goal.
