- A
Need-to-know, because users only see the data assigned to them.
Why wrong: Need-to-know limits data visibility to people with a business reason. The question is about multiple layers of protection, not about restricting data access.
- B
Separation of duties, because no single person performs every security task.
Why wrong: Separation of duties divides responsibilities among people to reduce fraud or abuse. The question describes stacked safeguards, not divided job responsibilities.
- C
Defense in depth, because multiple layers protect the same asset.
Defense in depth uses several different safeguards so one failure does not expose the asset. MFA, endpoint protection, firewalls, and segmentation are layered controls that work together to reduce risk if one layer fails.
- D
Zero trust, because the portal is hosted in the cloud.
Why wrong: Zero trust is based on continuous verification and not assuming trust based on location. A cloud deployment alone does not automatically make a design zero trust.
SY0-701 General Security Concepts Practice Question
This SY0-701 practice question tests your understanding of general security concepts. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 company uses MFA, endpoint protection, firewalls, and network segmentation together to protect a customer portal. Which security principle does this best illustrate?
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
Defense in depth, because multiple layers protect the same asset.
Defense in depth is the correct principle because the company is deploying multiple, overlapping security controls—MFA, endpoint protection, firewalls, and network segmentation—to protect the same customer portal. This layered approach ensures that if one control fails (e.g., a firewall rule is misconfigured), other controls (e.g., endpoint detection or segmentation) still provide protection, reducing the overall risk of a single point of compromise.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Need-to-know, because users only see the data assigned to them.
Why it's wrong here

Why it's wrong here

Why this is correct
Defense in depth uses several different safeguards so one failure does not expose the asset. MFA, endpoint protection, firewalls, and segmentation are layered controls that work together to reduce risk if one layer fails.

Zero trust, because the portal is hosted in the cloud.
Why it's wrong here
Zero trust is based on continuous verification and not assuming trust based on location. A cloud deployment alone does not automatically make a design zero trust.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse 'defense in depth' with 'zero trust' because both involve multiple controls, but zero trust specifically requires continuous verification and least-privilege access for every request, whereas defense in depth is simply the layering of independent controls without necessarily requiring per-request verification.
Detailed technical explanation
How to think about this question
Defense in depth, also known as layered security, leverages the principle that no single control is infallible; for example, a firewall might block external traffic on port 443, but an endpoint protection agent (e.g., EDR) can detect and block a malicious payload that bypasses the firewall via an allowed application. In practice, network segmentation (e.g., VLANs or ACLs) isolates the customer portal from internal resources, while MFA (e.g., TOTP or FIDO2) adds an authentication layer that mitigates credential theft, creating a resilient security posture that aligns with NIST SP 800-53's 'Protective Technology' family.
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 security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
