Full question →mediummultiple choiceObjective-mapped
A security analyst notices repeated attempts to copy large amounts of data to USB drives from a user's workstation. The analyst suspects the user may be exfiltrating company proprietary data. The company wants to implement a technical control that can both detect and block such data exfiltration without completely disabling all USB ports, as some users require USB for authorized work. Which of the following would best meet this requirement?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Implement a host-based intrusion detection system (HIDS) that alerts on USB insertion events.
A HIDS can detect USB insertion and generate alerts, but it does not actively block data transfers. The requirement specifies both detection and blocking, so this option is insufficient.
B
Best answer
Deploy a data loss prevention (DLP) agent configured with rules to monitor and block unauthorized data transfers to removable media.
A DLP agent can inspect data in real time, apply policies to classify sensitive content, and block transfers that violate company rules. This meets the need to both detect and block exfiltration while still permitting authorized USB use.
C
Distractor review
Enable BitLocker encryption on all USB drives to prevent unauthorized data access.
BitLocker encrypts the contents of USB drives, protecting data if the drive is lost or stolen. However, it does not prevent data from being copied to the drive in the first place, so it does not address the exfiltration problem.
D
Distractor review
Configure the local group policy to disable all USB ports on all workstations.
Disabling all USB ports would prevent any USB use, including authorized work. The scenario requires a solution that still allows some users to use USB drives for legitimate purposes, making this option too restrictive.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this SY0-701 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Deploy a data loss prevention (DLP) agent configured with rules to monitor and block unauthorized data transfers to removable media. — A Data Loss Prevention (DLP) agent can be configured with policies that monitor data content and destination, alerting or blocking transfers that violate rules. This allows authorized USB use while preventing unauthorized data exfiltration. Other options either lack blocking capability (HIDS), fail to prevent copying (BitLocker), or are too restrictive (disabling all USB ports).
