The answer is implementing endpoint device control or DLP rules to restrict removable media use. This is correct because Data Loss Prevention (DLP) solutions are specifically designed to monitor, block, or enforce policies on data transfers to external devices like USB drives, directly preventing data exfiltration via removable media. On the Security+ SY0-701 exam, this concept tests your understanding of DLP endpoint device control as a technical control for data-at-rest and data-in-use protection, often appearing in scenario-based questions where you must choose the most specific countermeasure against unauthorized copying. A common trap is selecting a general policy or awareness training instead of a technical enforcement mechanism, so remember that DLP rules actively enforce restrictions rather than just advising against them. Memory tip: think of DLP as a digital bouncer at the USB port—it checks every file trying to leave and stops sensitive data from walking out the door.
SY0-701 General Security Concepts Practice Question
This SY0-701 practice question tests your understanding of general security concepts. 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.
Exhibit
Current controls on finance laptops:
- Full-disk encryption enabled
- SIEM alerting on impossible-travel logins
- Weekly security awareness reminders
- USB ports left enabled for engineering and finance teams
Incident summary:
- Two finance users copied monthly revenue files to personal flash drives after downloading them
- Internet access and email must remain available for normal work
Based on the exhibit, which additional control is the best fit to prevent employees from copying sensitive reports to removable media?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.

A
Block all internet access on finance laptops except for the accounting website.
Why wrong: This is far broader than needed and would disrupt normal work. The problem is removable-media copy risk, not general internet use.
B
Implement endpoint device control or DLP rules to restrict removable media use.
This is the best control because the incident involves data being copied to USB devices. Awareness and encryption do not stop a user from transferring files to removable media. Endpoint device control or DLP can block, log, or limit USB storage use, directly reducing the exfiltration path while preserving normal internet and email access.
C
Increase the password complexity requirements for finance users.
Why wrong: Stronger passwords do not address local data copying to USB drives. The data leaves through a physical channel, so authentication strength is not the primary issue.
D
Add more antivirus signatures to the endpoint protection platform.
Why wrong: Antivirus is useful against malware, but it does not stop legitimate users from copying sensitive reports to flash drives. The incident is a data-loss problem, not a malware-detection problem.

Correct answer & explanation
✓
Implement endpoint device control or DLP rules to restrict removable media use.
Endpoint device control or DLP (Data Loss Prevention) rules are specifically designed to monitor, block, or restrict the use of removable media such as USB drives. By implementing such controls, an organization can enforce policies that prevent sensitive data from being copied to unauthorized external storage devices, directly addressing the threat of data exfiltration via removable media.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse network-based controls (like web filtering) with physical data exfiltration controls, or they mistakenly believe that stronger authentication or antivirus updates can prevent intentional data copying to removable media.
Detailed technical explanation
How to think about this question
Endpoint device control typically operates by intercepting system calls to the operating system's storage stack, using filter drivers or kernel-mode callbacks to evaluate device insertion requests against a policy. DLP solutions can further inspect file metadata, content patterns (e.g., credit card numbers via regex), and apply rights management or encryption before allowing a write operation. In a real-world scenario, a finance user might attempt to copy a PDF containing PII to a USB drive; a DLP agent would scan the file, detect sensitive data, and block the transfer while logging the incident for audit.

TExam Day Tips
→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 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. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
