- A
Enforcing multi-factor authentication for all external users.
MFA prevents login even if passwords are guessed, reducing the risk of unauthorized access.
- B
Requiring all file transfers to use SFTP instead of HTTPS.
Why wrong: SFTP and HTTPS both provide encryption; the issue is authentication, not protocol choice.
- C
Implementing file-level encryption with keys stored on-premises.
Why wrong: Encryption protects data at rest but does not block initial access with guessed credentials.
- D
Configuring the service to use a custom domain certificate.
Why wrong: Custom certificates enhance trust but do not improve password security.

SSCP Practice Question: Uses a cloud-based file synchronization service…
This SSCP practice question tests your understanding of sscp exam topics. 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.
An organization uses a cloud-based file synchronization service to share project files with external partners. The security team discovers that an unauthorized third party accessed sensitive documents by guessing weak passwords. Which additional control would most effectively mitigate this risk?
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
✓
Enforcing multi-factor authentication for all external users.
Option A is correct because multi-factor authentication directly addresses credential guessing by requiring a second factor. Option B is incorrect because SFTP does not inherently provide stronger authentication than HTTPS. Option C is incorrect because file-level encryption with on-premises keys does not prevent unauthorized access if the attacker already has valid credentials. Option D is incorrect because a custom domain certificate does not affect authentication strength.
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
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 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.
