- A
Enable Secure Boot in firmware.
Secure Boot helps ensure the device only starts trusted boot components that are signed by a trusted key. That reduces the risk of booting unapproved loaders or malicious recovery media. It is a platform hardening control that directly addresses firmware-level trust during startup, which is exactly what the scenario calls for.
- B
Implement application allowlisting or application control.
Application allowlisting controls which programs can execute on the endpoint, so only approved software runs. This is the correct control when the goal is to prevent unsanctioned utilities from launching after the system boots. Combined with Secure Boot, it covers both startup integrity and runtime execution restrictions.
- C
Rely only on full-disk encryption to stop unauthorized boot code.
Why wrong: Full-disk encryption protects data at rest, but it does not stop a machine from attempting to boot untrusted media. An attacker could still boot into alternate code if firmware settings are weak. Encryption is valuable, but it does not solve the specific boot-control problem described here.
- D
Increase the screen-lock timeout so users are interrupted less often.
Why wrong: Screen lock timing affects idle-session exposure, not startup trust or software execution. It may be useful for operational convenience, but it does nothing to stop unauthorized boot devices or unapproved applications. The scenario requires platform hardening, not a user-inactivity setting.
- E
Use a stronger Wi-Fi password so malware cannot start.
Why wrong: Wi-Fi password strength does not control firmware boot behavior or local application execution. Malware can start from many other pathways, and wireless credentials do not substitute for endpoint hardening. This option addresses the wrong layer of the system.
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 help desk manager is hardening a fleet of Windows laptops. The goal is to prevent booting from untrusted external media and to ensure only approved software can run on the devices. Which two controls best address those goals? Select two.
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
Enable Secure Boot in firmware.
Secure Boot is a UEFI firmware feature that verifies the digital signature of the bootloader against a database of trusted signatures stored in the firmware. By enabling Secure Boot, the system will refuse to boot from any external media (e.g., USB drives) that does not have a valid, trusted signature, directly preventing unauthorized boot code from executing.
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 full-disk encryption with boot security, mistakenly thinking encryption prevents unauthorized boot media, when in fact encryption only protects data confidentiality and does not control the boot process or software execution.

Detailed technical explanation
How to think about this question
Secure Boot relies on the UEFI firmware's signature database (db) and forbidden signature database (dbx). When a bootloader is loaded, its signature is checked against these databases; if the signature is not trusted or is revoked, the boot process halts. Application allowlisting (e.g., Windows Defender Application Control or AppLocker) enforces a policy that only executables with a specific publisher, hash, or path are allowed to run, blocking all unapproved software at runtime.
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.
