Correct answer & explanation

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 plaintext password of the Domain Administrator
Why it's wrong here
Plaintext passwords are not needed if the NTLM hash is known.
- ✗
The Domain Controller's computer account machine password
Why it's wrong here
Golden tickets require KRBTGT; Silver tickets require the specific service account's hash.
- ✓
The NTLM password hash of the specific service account
Why this is correct
Silver tickets encrypt the service ticket using the target service account's NTLM hash.
- ✗
The domain root CA private key (.pfx)
Why it's wrong here
CA private keys are used for PKI/AD CS attacks, not Kerberos Silver Tickets.
