The answer is application control using an allowlist for approved executables and publishers. This control is correct because it explicitly defines which software is permitted to run, blocking any unauthorized tools downloaded from the internet while allowing approved internal apps and vendor-updated software that match criteria like file hashes or publisher signatures. On the Security+ SY0-701 exam, this scenario tests your understanding of application control as a host-based security measure that prevents execution of unapproved code, often contrasted with application blocklisting, which is a common trap—blocklists are reactive and easily bypassed by new malware variants. A useful memory tip is “allowlist, not blocklist,” since allowlisting explicitly denies everything not on the list, making it far more effective against unauthorized software.
SY0-701 Security Architecture Practice Question
This SY0-701 practice question tests your understanding of security architecture. 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 company wants to stop employees from running unauthorized tools downloaded from the internet on managed Windows laptops, but still allow approved internal apps and vendor-updated software. Which control is best?

Correct answer & explanation
✓
Application control using an allowlist for approved executables and publishers.
Application control with an allowlist (also known as whitelisting) is the correct choice because it explicitly defines which executables, scripts, and publishers are permitted to run on managed Windows laptops. This prevents unauthorized tools downloaded from the internet from executing, while allowing approved internal apps and vendor-updated software that match the allowlist criteria. Technologies like Windows Defender Application Control (WDAC) or AppLocker enforce this by checking file hashes, publisher signatures, or path rules at runtime.
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.
✓
Application control using an allowlist for approved executables and publishers.
Why this is correct
Allowlisting blocks unapproved software while still permitting known-good internal and vendor-signed applications.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Full-disk encryption on every laptop before deployment.
Why it's wrong here
Encryption protects data at rest, but it does not prevent users from launching unauthorized programs.
✗
A stronger screen-lock timeout and automatic logoff policy.
Why it's wrong here
Session controls help reduce exposure, but they do not control which applications can execute on the endpoint.
✗
A firmware password for the BIOS without any other endpoint restrictions.
Why it's wrong here
Firmware passwords help protect boot settings, but they do not stop users from running unwanted software inside the OS.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse data-at-rest protection (encryption) or session management (screen lock) with application execution control, mistakenly thinking they can prevent unauthorized software from running, when in fact they address entirely different security domains.
Detailed technical explanation
How to think about this question
Under the hood, allowlisting works by intercepting process creation requests via a kernel-mode filter driver (e.g., AppLocker's appid.sys) and comparing the executable's attributes—such as Authenticode signature, publisher, or SHA-256 hash—against a predefined policy. In a real-world scenario, a company might use WDAC with a managed installer rule to automatically trust software deployed via Microsoft Intune or SCCM, while blocking any unsigned or unapproved binary, even if the user has administrative rights.

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.
