SY0-701 Security Operations Practice Question

This SY0-701 practice question tests your understanding of security operations. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 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?

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.

Question 1mediummultiple choice

Full question →

A
Implement a host-based intrusion detection system (HIDS) that alerts on USB insertion events.
Why wrong: 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
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
Enable BitLocker encryption on all USB drives to prevent unauthorized data access.
Why wrong: 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
Configure the local group policy to disable all USB ports on all workstations.
Why wrong: 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.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Deploy a data loss prevention (DLP) agent configured with rules to monitor and block unauthorized data transfers to removable media.

Option B is correct because a Data Loss Prevention (DLP) agent can be configured with granular rules to monitor and block unauthorized data transfers to removable media (e.g., USB drives) based on content inspection, file type, or volume thresholds. This allows authorized USB usage while preventing exfiltration of proprietary data, meeting the requirement for both detection and blocking without disabling all USB ports.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
Implement a host-based intrusion detection system (HIDS) that alerts on USB insertion events.
Why it's wrong here
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.
✓
Deploy a data loss prevention (DLP) agent configured with rules to monitor and block unauthorized data transfers to removable media.
Why this is correct
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.

✗
Enable BitLocker encryption on all USB drives to prevent unauthorized data access.
Why it's wrong here
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.
✗

Why it's wrong here
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 traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse detection-only controls (like HIDS alerts) with prevention controls, or they assume encryption (BitLocker) can stop data exfiltration, when in fact encryption only protects data at rest and does not prevent copying from the host.

Detailed technical explanation

How to think about this question

DLP agents operate by hooking into the operating system's file system driver (e.g., using minifilter drivers on Windows) to intercept read/write operations to removable media in real time. They can apply rules based on regex patterns for sensitive data (e.g., credit card numbers, social security numbers), file extensions, or volume thresholds (e.g., >100 MB in 5 minutes), and can block the transfer or quarantine the file while logging the event for audit. In a real-world scenario, a DLP agent might allow a user to copy a presentation to a USB drive but block a script attempting to copy a database export, all without requiring USB port disablement.

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.

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 developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
