Question 697 of 1,152
Security ArchitecturemediumMultiple ChoiceObjective-mapped

Quick Answer

The correct choice is full-disk encryption with a hardware-backed key store like a TPM, preferably combined with a pre-boot PIN. This works because the TPM securely stores the decryption key on the laptop’s motherboard, so even if the drive is removed and placed in another system, the key remains inaccessible without the original TPM. Adding a pre-boot PIN introduces a second authentication factor, ensuring that both the physical hardware and the user’s knowledge are required to decrypt the data. On the Security+ SY0-701 exam, this scenario tests your understanding of data-at-rest protection and the difference between software-based encryption and hardware-backed solutions. A common trap is choosing BitLocker without a TPM or relying solely on a password, which can be bypassed by removing the drive. Remember the mnemonic “TPM + PIN = locked-in” to recall that the TPM binds the key to the hardware, and the PIN adds a layer only the user knows.

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.

Sales staff use company laptops on public Wi-Fi and travel frequently. The company wants the disk contents unreadable if a laptop is stolen, even if the drive is removed and placed in another system. Which control is the best fit?

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.

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 full-disk encryption with a hardware-backed key store such as a TPM, preferably with a pre-boot PIN.

Full-disk encryption (FDE) with a hardware-backed key store like a TPM ensures that the entire disk contents are encrypted at rest. Even if the drive is removed and placed in another system, the decryption key remains bound to the original TPM, and a pre-boot PIN adds an additional authentication factor, making the data unreadable without both the TPM and the correct PIN.

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.

  • Require a screen lock after five minutes of inactivity.

    Why it's wrong here

    A screen lock helps with casual access, but it does not protect data from drive removal attacks.

  • Enable full-disk encryption with a hardware-backed key store such as a TPM, preferably with a pre-boot PIN.

    Why this is correct

    Full-disk encryption protects data at rest, and hardware-backed keys prevent the drive from being read outside the original device.

    Clue confirmation

    The clue word "best" in the question point toward this answer.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Encrypt only the most sensitive folders with file-level encryption.

    Why it's wrong here

    File-level encryption leaves other data exposed and is less effective against full-drive theft scenarios.

  • Rely on remote wipe because the device will usually connect to the internet again.

    Why it's wrong here

    Remote wipe is useful, but it cannot be guaranteed before an attacker accesses the offline drive.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often choose remote wipe (Option D) because it sounds proactive, but they overlook the critical requirement that the device must be online for remote wipe to work, which is not guaranteed for a stolen laptop that may never connect to the internet.

Detailed technical explanation

How to think about this question

Full-disk encryption (e.g., BitLocker with TPM) encrypts the entire volume using a symmetric key (the Full Volume Encryption Key, FVEK) that is itself encrypted by the TPM's storage root key (SRK). The TPM seals the key to the specific hardware state, so even if the drive is moved to another system, the TPM will not release the key, and without the pre-boot PIN, the key remains inaccessible. In a real-world scenario, an attacker could attempt a cold boot attack, but a TPM with a PIN mitigates this by requiring authentication before the key is unsealed.

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.
