- A
Enable Secure Boot and set a UEFI administrator password.
Why wrong: Secure Boot ensures only signed OS boot loaders run, but it does not prevent booting from USB drives if they are in the boot order; a password alone doesn't restrict boot devices.
- B
Disable all external boot devices in the UEFI boot order and set a supervisor password.
Disabling external boot devices in the boot order prevents the system from attempting to boot from them; a supervisor password prevents unauthorized changes to these settings.
- C
Set the boot mode to Legacy BIOS and disable USB support.
Why wrong: Legacy BIOS may still allow booting from USB depending on configuration; disabling USB support entirely would also disable keyboard/mouse, making the kiosk unusable.
- D
Enable the TPM and set a power-on password.
Why wrong: TPM is for encryption and attestation, not boot control; a power-on password prevents unauthorized access but does not restrict boot devices.
Quick Answer
The answer is to disable all external boot devices in the UEFI boot order and set a supervisor password. This works because UEFI firmware controls the boot sequence at a hardware level, so removing USB and optical media from the boot list ensures the system only loads from the internal SSD, while the supervisor password locks those settings from being tampered with by a public user. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding of UEFI security versus legacy BIOS—a common trap is thinking that simply changing the boot order is enough, but without a password, anyone can reboot and re-enable USB booting. To prevent booting from USB in UEFI for public kiosk security, remember the two-step rule: strip the boot list, then lock the door. A useful memory tip is “Order then Ward”—set the boot order first, then guard it with a password.
220-1101 BIOS / UEFI Practice Question
This 220-1201 practice question tests your understanding of bios / uefi. 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 technician is tasked with securing a workstation that will be used in a public kiosk. The requirement is that the system must only boot from the internal SSD and must prevent booting from USB drives or optical media. Which UEFI security feature should be configured?
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
Disable all external boot devices in the UEFI boot order and set a supervisor password.
To prevent unauthorized booting from external media, the technician must set a boot order that prioritizes the internal SSD and disable other boot devices. Additionally, setting a UEFI administrator password prevents unauthorized users from changing these settings.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

- ✗
Enable Secure Boot and set a UEFI administrator password.
Why it's wrong here
Secure Boot ensures only signed OS boot loaders run, but it does not prevent booting from USB drives if they are in the boot order; a password alone doesn't restrict boot devices.
- ✓
Disable all external boot devices in the UEFI boot order and set a supervisor password.
Why this is correct
Disabling external boot devices in the boot order prevents the system from attempting to boot from them; a supervisor password prevents unauthorized changes to these settings.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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 practitioner preparing for the 220-1201 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
