Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A branch office uses a flat LAN, and a compromise on one user workstation could spread quickly to finance systems. Management wants finance workstations isolated from general users, but finance staff still need access to a central finance application and network printer. What is the best design change?
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
Move finance devices to the guest Wi-Fi network so they are separated from employees.
Guest Wi-Fi is usually less trusted and is not an appropriate zone for business systems needing controlled access.
B
Best answer
Create separate VLANs for finance and user devices, then apply inter-VLAN ACLs to allow only required application and printer traffic.
Separate VLANs provide segmentation, and inter-VLAN ACLs enforce which systems may communicate. This limits lateral movement while still allowing the finance team to reach approved shared resources such as the finance application and printer.
C
Distractor review
Keep the flat LAN but require stronger passwords on finance PCs and shared folders.
Stronger passwords help account security, but they do not stop a compromised host from scanning or attacking other systems on the same network.
D
Distractor review
Place all devices in one VLAN and rely on endpoint antivirus to stop spread.
Endpoint antivirus is important, but it does not replace network segmentation for reducing lateral movement and controlling traffic paths.
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: Create separate VLANs for finance and user devices, then apply inter-VLAN ACLs to allow only required application and printer traffic. — The best approach is to separate devices into VLANs and then control traffic between those VLANs with ACLs or firewall rules. That design limits broadcast domains and reduces the ability of a compromised user workstation to reach finance assets. It also allows only the necessary application and printer traffic, which is a practical balance between security and business use. Segmentation is especially important in branch offices where flat networks are easy to abuse. Why others are wrong: Option A places business systems in an untrusted zone and would create operational and security problems. Option C does not address network lateral movement. Option D depends on malware defenses alone and ignores the stronger control of segmentation and traffic filtering.
