Question 1easymultiple choice
Full question →easymultiple choiceObjective-mapped
Guest tablets in a conference room use the same physical switches as employee devices. The security team wants guests to have internet access only, with no route to internal subnets. Which design best meets the goal?
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
Distractor review
Keep guests on the same VLAN and rely on a separate Wi-Fi password.
A different password does not stop routing between guest and internal devices on the same segment.
B
Best answer
Place guests on a separate VLAN and block internal access with ACLs.
A separate VLAN creates logical segmentation, and ACLs enforce which networks the guests can reach.
C
Distractor review
Use stronger WPA3 encryption on the wireless network and leave the network flat.
Stronger encryption protects the wireless link, but it does not separate guest traffic from internal systems.
D
Distractor review
Enable MAC address filtering on the switch and allow all ports to remain in the default network.
MAC filtering is easy to bypass and does not provide the network isolation the team needs.
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: Place guests on a separate VLAN and block internal access with ACLs. — A separate guest VLAN keeps visitor traffic logically isolated from employee traffic, even when they share the same physical switching infrastructure. Access control lists then limit which destinations the guest network can reach, such as allowing internet access while denying internal subnets. This is a common and effective way to reduce risk from unmanaged or less-trusted devices. Why others are wrong: A different password does not separate traffic once devices are on the same network. WPA3 only protects the wireless connection; it does not enforce internal segmentation. MAC filtering is weak and not a real boundary for guest isolation, so it should not be the primary control.
