- A
The service account password must be weak
Why wrong: Weak password is not a condition; it only affects cracking success.
- B
The domain must be using NTLM authentication
Why wrong: Kerberos is used for Kerberoasting.
- C
The attacker must have domain admin privileges
Why wrong: Any domain user can request TGS tickets for Kerberoasting.
- D
The attacker must be able to request TGS tickets from the domain controller
TGS tickets are necessary for offline cracking.
- E
The service account must have a Service Principal Name (SPN) registered
SPN is required to request a TGS ticket for that account.

PT0-002 Attacks and Exploits Practice Question
This PT0-002 practice question tests your understanding of attacks and exploits. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
A penetration tester is assessing an Active Directory environment and wants to perform Kerberoasting to obtain service account passwords. Which TWO conditions are required for a successful Kerberoasting attack?
Answer choices
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
✓
The attacker must be able to request TGS tickets from the domain controller
A domain account with a Service Principal Name (SPN) and the ability to request a TGS ticket are required for Kerberoasting.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The service account password must be weak
Why it's wrong here
Weak password is not a condition; it only affects cracking success.
- ✗
The domain must be using NTLM authentication
Why it's wrong here
Kerberos is used for Kerberoasting.
- ✗
The attacker must have domain admin privileges
Why it's wrong here
Any domain user can request TGS tickets for Kerberoasting.
- ✓
The attacker must be able to request TGS tickets from the domain controller
Why this is correct
TGS tickets are necessary for offline cracking.
Related concept
Authentication checks who the user is.
- ✓
The service account must have a Service Principal Name (SPN) registered
Why this is correct
SPN is required to request a TGS ticket for that account.
Related concept
Authentication checks who the user is.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
How this comes up in practice
A security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
What to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related PT0-002 questions on access control and AAA configuration.
