The correct answer is to decode the base64-encoded command-line argument, as this is the most appropriate hunting technique when investigating a suspicious Word process that spawned with an '-enc' flag. Base64 encoding is frequently used in malicious documents to obfuscate payloads, particularly for PowerShell commands, and decoding the argument directly reveals the attacker’s intended command without further analysis. On the SC-200 exam, this scenario tests your ability to recognize common obfuscation patterns in process creation events, often appearing in threat hunting questions where a seemingly benign Office application launches a hidden script. A common trap is assuming the '-enc' flag is exclusive to PowerShell, but it can appear in other contexts; the key is that decoding is always the immediate next step, not network traffic or hash lookups. Memory tip: think of '-enc' as “encode” — when you see it, your first move is to decode.
SC-200 Perform threat hunting Practice Question
This SC-200 practice question tests your understanding of perform threat hunting. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. 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.
During a threat hunt, you identify a suspicious process that spawned from Microsoft Word with a command-line argument containing ' -enc '. Which hunting technique is most appropriate to investigate this further?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Decode the base64-encoded command-line argument
Option B is correct because base64-encoded command lines are commonly used in malicious documents to obfuscate payloads. Decoding the argument reveals the intended command. Option A is incorrect because decoding is not limited to PowerShell. Option C is incorrect because network traffic analysis may follow but is not the immediate next step. Option D is incorrect because file hash lookup is less relevant for the encoded command.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Review the PowerShell script block logging
Why it's wrong here
While script block logging is useful, the immediate need is to decode the base64 argument.
✗
Initiate network traffic analysis for the host
Why it's wrong here
Network analysis is a later step after understanding the command.
✗
Check the file hash against threat intelligence feeds
Why it's wrong here
Hash lookup is less relevant for encoded commands; the process itself may be legitimate.
✓
Decode the base64-encoded command-line argument
Why this is correct
Base64 decoding reveals the actual command executed, aiding in understanding the threat.

Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
