- A
Deploy 802.1X with EAP-TLS so devices prove possession of a unique certificate.
EAP-TLS uses device certificates to authenticate the endpoint, which is far stronger than a shared password. Because each managed laptop has its own certificate, access can be tied to the device identity rather than a static secret. This is a common enterprise wireless control for preventing unmanaged devices from joining corporate Wi-Fi.
- B
Use a single WPA3-Personal passphrase printed in the lobby for all managed devices.
Why wrong: A shared passphrase does not verify device identity and is easy to leak or reuse.
- C
Rely on MAC address allow lists because they cannot be forged easily.
Why wrong: MAC addresses are not a strong control because they can be spoofed and are not proof of compliance.
- D
Enforce NAC posture checks and move noncompliant devices to a remediation VLAN.
NAC posture assessment checks whether the endpoint meets required security conditions before granting normal access. If a device lacks EDR, encryption, or other required settings, placing it in a remediation VLAN lets IT fix the issue without giving the device full network access. This directly supports quarantine and compliance enforcement.
- E
Hide the SSID and disable client isolation to reduce discovery by attackers.
Why wrong: Hidden SSIDs do not provide real security, and client isolation is unrelated to managed-device compliance.
Quick Answer
The answer is to enforce NAC posture checks and move noncompliant devices to a remediation VLAN. This combination works because 802.1X with EAP-TLS provides certificate-based authentication, ensuring only company-managed laptops with a valid PKI-issued client certificate can connect, while Network Access Control (NAC) continuously monitors device compliance—such as antivirus updates or patch levels—and dynamically shunts noncompliant devices into a restricted remediation VLAN for self-healing. On the Security+ SY0-701 exam, this scenario tests your understanding of how 802.1X and NAC work together for wireless compliance, often appearing in questions about replacing shared secrets like WPA2-PSK with stronger, per-device identity controls. A common trap is to select only EAP-TLS and forget the NAC posture-check component, but the requirement explicitly demands quarantine for noncompliant devices, not just authentication. Memory tip: think “certificate to connect, NAC to correct.”
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.
An office is replacing WPA2-PSK. The new design must ensure only company-managed laptops can join the wireless network, and any device that falls out of compliance must be blocked or quarantined until remediated. Which two controls best meet the requirement? Select two.

Correct answer & explanation
Deploy 802.1X with EAP-TLS so devices prove possession of a unique certificate.
802.1X with EAP-TLS is correct because it requires each device to present a unique client certificate issued by the company's PKI. This ensures only company-managed laptops (which have the certificate) can authenticate, and it ties directly into the requirement for device-specific identity rather than a shared secret.
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 often confuse WPA3-Personal's improved encryption with authentication control, but it still relies on a shared passphrase and cannot enforce per-device identity or compliance checks.

Detailed technical explanation
How to think about this question
802.1X with EAP-TLS uses the Extensible Authentication Protocol (EAP) over RADIUS, where the client presents an X.509 certificate to the authentication server (e.g., FreeRADIUS or NPS). The server validates the certificate chain and checks revocation status via OCSP or CRL, ensuring only devices with valid, unexpired certificates gain access. NAC posture checks (option D) complement this by evaluating endpoint health (e.g., antivirus version, patch level) and dynamically assigning noncompliant devices to a remediation VLAN with restricted access.
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.
