A help desk technician receives an alert that an unmanaged laptop was plugged into a conference room network jack and was automatically placed into a restricted network segment until it passed a security check. Which control is responsible for that behavior?
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
Network access control (NAC).
NAC can authenticate devices, check posture, and place noncompliant systems into a limited or quarantine network segment.
B
Distractor review
Data loss prevention (DLP).
DLP monitors data movement and sensitive content, but it does not decide whether a device may join the network.
C
Distractor review
Intrusion prevention system (IPS).
An IPS can block malicious traffic, but it does not perform device admission control or assign a remediation VLAN.
D
Distractor review
Sandboxing gateway.
Sandboxing is used to detonate suspicious files or links, not to control network access for endpoint devices.
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: Network access control (NAC). — NAC is the correct control because it evaluates a device before or as it joins the network and can enforce posture checks, authentication, and quarantine or remediation VLAN placement. This behavior is common when an unmanaged or noncompliant device is detected on a port. NAC is especially useful for controlling access in office environments where both managed and unmanaged devices may physically connect to network ports. Why others are wrong: DLP is about protecting sensitive data from leaving the organization, not about device admission. IPS blocks malicious traffic patterns after a device is already connected, but it does not control initial access or posture enforcement. Sandboxing analyzes suspicious content rather than endpoint access. The clue is the restricted network segment after connection, which is a hallmark of NAC.
