- A
Enable Secure Boot in firmware and block external boot devices where possible.
Secure Boot checks boot components against trusted signatures before they are allowed to run, which directly addresses tampered or untrusted pre-boot code. Disabling external boot adds another layer by reducing the chance of unauthorized removable media being used to bypass protections.
- B
Turn on screen lock after ten minutes of inactivity.
Why wrong: Screen locking protects an unlocked session, but it does nothing to stop malicious code from loading before the operating system starts.
- C
Increase the password complexity policy for user accounts.
Why wrong: Stronger passwords help account security, but they do not prevent a device from booting an untrusted loader.
- D
Disable Windows Defender notifications on the endpoints.
Why wrong: Suppressing alerts reduces visibility and does not mitigate the underlying firmware or boot-chain problem.
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.
Several company laptops were found to boot from a removable drive containing an untrusted pre-boot utility before the operating system loaded. The security team wants to prevent unsigned or tampered boot code from starting. Which control is the best fit?

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 and block external boot devices where possible.
Secure Boot is a UEFI firmware feature that verifies the digital signature of boot code against a trusted database before execution. By enabling Secure Boot and blocking external boot devices, the security team ensures that only signed, trusted bootloaders and drivers can run, preventing untrusted pre-boot utilities from loading. This directly addresses the scenario where laptops boot from a removable drive containing unsigned or tampered boot code.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why this is correct
Secure Boot checks boot components against trusted signatures before they are allowed to run, which directly addresses tampered or untrusted pre-boot code. Disabling external boot adds another layer by reducing the chance of unauthorized removable media being used to bypass protections.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse endpoint security controls (like screen lock or password policies) with boot-time integrity mechanisms, failing to recognize that Secure Boot is the only option that validates code before the OS loads.
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 boot device is selected, the firmware checks the bootloader's signature against db; if missing or revoked, boot is halted. In a real-world scenario, an attacker could use a bootable USB with a modified bootkit like BootHole to bypass OS-level defenses, making Secure Boot combined with locked boot order a critical defense-in-depth measure.
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 SOC analyst notices unusual lateral movement in the network at 2 AM. The IR playbook dictates: identify and contain (isolate the affected machine), then eradicate (remove the malware), then recover (restore from backup), then document. Skipping containment before eradication risks the attacker regaining access. Questions like this test the sequence and rationale of incident response phases.
