- A
Session key
Why wrong: Session keys are used to encrypt communications, but their expiration is not typically user-facing.
- B
Ticket-Granting Ticket (TGT)
TGT expiration requires the user to re-authenticate to the KDC to obtain a new TGT.
- C
Service ticket
Why wrong: Service tickets are short-lived and obtained using the TGT. A service ticket expiration would affect only that service, not the entire session.
- D
Authentication Server (AS) reply
Why wrong: The AS reply is a one-time message, not a ticket that expires.

SSCP Access Controls Practice Question
This SSCP practice question tests your understanding of access controls. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An organization uses Kerberos for SSO. A user reports that after entering their password, they receive a 'ticket expired' error when trying to access a network share. The system administrator checks the Kerberos configuration. Which ticket is most likely expired?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"most likely"Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Ticket-Granting Ticket (TGT)
The Ticket-Granting Ticket (TGT) has a limited lifetime (typically 8-10 hours). When it expires, the user must re-authenticate to get a new TGT.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
