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.
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
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
Distractor review
Use a single WPA3-Personal passphrase printed in the lobby for all managed devices.
A shared passphrase does not verify device identity and is easy to leak or reuse.
C
Distractor review
Rely on MAC address allow lists because they cannot be forged easily.
MAC addresses are not a strong control because they can be spoofed and are not proof of compliance.
D
Best answer
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
Distractor review
Hide the SSID and disable client isolation to reduce discovery by attackers.
Hidden SSIDs do not provide real security, and client isolation is unrelated to managed-device compliance.
Common exam trap
Common exam trap: an active trunk can still block the VLAN you need
A trunk being up does not prove every VLAN is crossing it. Check allowed VLAN lists, native VLAN mismatch, VLAN existence and access-port assignment.
Technical deep dive
How to think about this question
VLAN questions usually combine access-port and trunking clues. The key is to identify whether the issue is local to one switchport, caused by the trunk, or caused by the VLAN not existing where it needs to exist.
KKey Concepts to Remember
- Access ports place end devices into a single VLAN.
- Trunk ports carry multiple VLANs between switches.
- Allowed VLAN lists decide which VLANs can cross a trunk.
- Native VLAN mismatch can create confusing symptoms.
TExam Day Tips
- Use show vlan brief to verify access VLANs.
- Use show interfaces trunk to verify trunk state and allowed VLANs.
- Do not treat every same-VLAN issue as a routing problem.

FAQ
Questions learners often ask
What does this SY0-701 question test?
Access ports place end devices into a single VLAN.
What is the correct answer to this question?
The correct answer is: Deploy 802.1X with EAP-TLS so devices prove possession of a unique certificate. — The strongest combination is certificate-based wireless authentication with 802.1X/EAP-TLS and network access control with posture checks. EAP-TLS ensures only trusted managed devices can authenticate to Wi-Fi using unique certificates. NAC then verifies the endpoint remains compliant and can quarantine devices that fall out of policy. Together, these controls address both identity and ongoing posture, which shared passwords cannot do. Why others are wrong: A shared WPA3 passphrase and MAC filtering do not prove device ownership or compliance. Hidden SSIDs are not a meaningful security control. The goal is to authenticate managed endpoints and enforce policy dynamically, which is why 802.1X plus NAC is the correct pairing.
