The answer is SecurityEvent | where EventID == 4769 and TicketEncryptionType == 0x17. This KQL query is correct because Kerberoasting detection relies on identifying Kerberos TGS requests for service principal names (SPNs) that use RC4 encryption, which is a known weakness attackers exploit to crack service account passwords offline. Event ID 4769 specifically logs every TGS request in Windows security logs, and filtering for TicketEncryptionType 0x17 isolates the RC4-encrypted tickets that are the hallmark of a Kerberoasting attack. On the SC-200 exam, this question tests your ability to distinguish between Kerberos event IDs: 4768 logs TGT requests (for initial authentication), while 4769 logs TGS requests (for service access). A common trap is confusing these two events or overlooking the encryption type filter. Remember the mnemonic “4769 for Service” to recall that TGS requests target SPNs, and “0x17 is RC4 heaven” for the encryption type attackers prefer.
SC-200 Perform threat hunting Practice Question
This SC-200 practice question tests your understanding of perform threat hunting. 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.
You are hunting for signs of Kerberoasting in Microsoft Sentinel. Which hunting query using KQL would you use to identify service principal names (SPNs) being queried via Kerberos TGS requests?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
SecurityEvent | where EventID == 4769 and TicketEncryptionType == 0x17
Kerberoasting involves requesting TGS tickets for SPNs. Option D is correct because SecurityEvent 4769 logs TGS requests, and TicketEncryptionType 0x17 indicates RC4 encryption used in Kerberoasting. Option A is incorrect because Event 4768 is for TGT requests. Option B is incorrect because DeviceLogonEvents may not contain SPN details. Option C is incorrect because DeviceEvents may not capture this security event.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✓
SecurityEvent | where EventID == 4769 and TicketEncryptionType == 0x17
Why this is correct
Event 4769 is TGS request; 0x17 is RC4 encryption.

Read the scenario before looking for a memorised answer.
✗
DeviceEvents | where ActionType == 'KerberosTicketRequest'
Why it's wrong here
ActionType may not be available.
✗
DeviceLogonEvents | where LogonType == 'Kerberos' and AccountDomain == 'Service'
Why it's wrong here
Does not capture SPN queries specifically.
✗
SecurityEvent | where EventID == 4768 and TicketEncryptionType == 0x17
Why it's wrong here
Event 4768 is for TGT requests, not TGS.
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.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
