Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Session key
Why it's wrong here
Session keys are used to encrypt communications, but their expiration is not typically user-facing.
- ✓
Ticket-Granting Ticket (TGT)
Why this is correct
TGT expiration requires the user to re-authenticate to the KDC to obtain a new TGT.
- ✗
Service ticket
Why it's wrong here
Service tickets are short-lived and obtained using the TGT. A service ticket expiration would affect only that service, not the entire session.
- ✗
Authentication Server (AS) reply
Why it's wrong here
The AS reply is a one-time message, not a ticket that expires.
