The answer is planting honey credentials for non-existent Active Directory accounts in a common password manager. This deception-based detection technique works because honey tokens—like fake usernames and passwords—appear legitimate to an attacker who has already breached the perimeter, but any use of them is a high-confidence indicator of lateral movement, as no legitimate user would ever need them. On the CompTIA SecurityX CAS-004 exam, this scenario tests your understanding of how to deploy decoys that blend into normal workflows without alerting the adversary; a common trap is choosing honeypots that require network interaction, which can be detected by experienced attackers. Remember the mnemonic “Honey Hides in Habits”—the best tokens are those an attacker would naturally find and use, like credentials in a password manager, rather than obvious traps that scream “deception.”
CAS-004 Security Operations Practice Question
This CAS-004 practice question tests your understanding of security operations. 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 security architect is designing a deception-based detection system for a high-security environment. The goal is to detect lateral movement by attackers who have already breached the perimeter. Which of the following deception techniques would be most effective at identifying an attacker without alerting them to the deception?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Plant honey credentials (username/password) for non-existent Active Directory accounts in a common password manager.
Option A is correct because honey tokens that appear as real credentials will be used only by attackers, and if used, provide high-confidence detection. Option B will alert attackers. Option C is easily detectable by experienced attackers. Option D may be ignored if attackers don't use network shares.
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.
✗
Configure a network share with honey files and monitor for file access.
Why it's wrong here
Network share access may be automated and not necessarily malicious.
✗
Create a honeypot web server with known vulnerabilities and monitor for interactions.
Why it's wrong here
Honeypots can be detected by attackers scanning for decoy systems.
✗
Deploy fake database tables containing plausible but fictitious data.
Why it's wrong here
Sophisticated attackers may check data authenticity.
✓
Plant honey credentials (username/password) for non-existent Active Directory accounts in a common password manager.
Why this is correct
Honey credentials are low interaction and high value; usage indicates compromise without tipping off attackers.

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 practitioner preparing for the CAS-004 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
