- A
Defense in depth
Why wrong: Defense in depth uses multiple layers, but the distinguishing feature here is continuous trust evaluation rather than just stacked controls.
- B
Zero trust
The portal does not trust the session simply because the user authenticated once. It repeatedly evaluates device posture and context before granting sensitive actions, and it can deny access when risk changes. That is the core of zero trust: verify explicitly, assume no persistent trust, and re-evaluate access continuously instead of relying on an initial login event.
- C
Least privilege
Why wrong: Least privilege would limit permissions to only what the user needs, but it does not specifically describe repeated trust checks during a session.
- D
Need-to-know
Why wrong: Need-to-know is about limiting access to information that is necessary for a task, not about re-evaluating session 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 web portal for customer refunds checks device health at sign-in, then re-checks the device and user context before each refund over a threshold. A session that started on a managed laptop is blocked when the laptop later fails posture checks, even though the password remains valid. Which principle is best illustrated?
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.

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
Zero trust
The scenario describes a system that continuously verifies trust—checking device health at sign-in and re-evaluating both device and user context before each high-value action—and blocks access even when the password is valid. This is the core of Zero Trust: 'never trust, always verify,' where authentication and authorization are re-assessed at every transaction, not just at session start. The policy enforces access decisions based on real-time posture (e.g., device compliance, user behavior) rather than relying solely on a static credential.
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
The trap here is that candidates confuse 'Zero Trust' with 'defense in depth' because both involve multiple security layers, but Zero Trust specifically mandates continuous re-validation of trust for each access request, not just layered static controls.
Detailed technical explanation
How to think about this question
Zero Trust architectures often use a Policy Enforcement Point (PEP) and Policy Decision Point (PDP) to evaluate signals like device certificate validity, OS patch level, and geolocation at each request. In this case, the portal likely integrates with a Network Access Control (NAC) or endpoint detection and response (EDR) tool that updates the device's posture score in real time; if the score drops below a threshold (e.g., missing critical patch), the PDP denies the refund action even though the user's session token is still valid. This aligns with NIST SP 800-207, which defines Zero Trust as requiring continuous verification of all assets and subjects.
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.
