The answer is Cisco Identity Services Engine (ISE) with downloadable ACLs (dACL) and VLAN assignment. This solution is correct because ISE dynamically enforces per-user policy at the network edge: when a guest authenticates via 802.1X, ISE uses RADIUS Change of Authorization (CoA) to place the user into a dedicated guest VLAN and simultaneously applies a dACL that permits only internet-bound traffic, while corporate users remain in their native VLAN with full internal access. On the Cisco SCOR 350-701 exam, this scenario tests your understanding of dynamic policy enforcement versus static VLAN configurations—a common trap is assuming a simple ACL on the switch port is sufficient, but the exam emphasizes that ISE’s ability to assign both VLAN and dACL per session is what meets the “internet-only” requirement without affecting corporate users. Remember the key pairing: VLAN for segmentation, dACL for restriction. A useful memory tip is “VLAN to separate, dACL to gate”—ISE handles both dynamically.
350-701 Network Security Practice Question
This 350-701 practice question tests your understanding of network security. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
A company wants to provide both corporate and guest wireless access using the same access points. They require that guest users be placed into a separate VLAN and have internet-only access. Which Cisco solution should be used?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Cisco Identity Services Engine (ISE) with dACL and VLAN assignment
Cisco ISE with downloadable ACLs (dACL) and VLAN assignment is the correct solution because it enables dynamic per-user policy enforcement. When a guest user authenticates, ISE can place them into a dedicated guest VLAN and apply a dACL that restricts traffic to internet-only access, while corporate users remain in their native VLAN with full internal access. This leverages RADIUS CoA (Change of Authorization) and 802.1X to dynamically assign VLANs and filter traffic at the access point or switch.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✓
Cisco Identity Services Engine (ISE) with dACL and VLAN assignment
Why this is correct
ISE can assign VLANs and downloadable ACLs based on user or device identity.

✗
Cisco Prime Infrastructure
Why it's wrong here
Prime Infrastructure is a network management tool, not a policy enforcement point.
✗
Cisco Flexible NetFlow
Why it's wrong here
Flexible NetFlow is a traffic monitoring feature, not a policy enforcement solution.
✗
Cisco TrustSec with SGT
Why it's wrong here
TrustSec uses security group tags for policy but does not directly assign VLANs.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Cisco Prime Infrastructure or TrustSec as policy enforcement tools, but Prime is only for management and TrustSec uses SGTs for role-based access, not direct VLAN assignment for guest isolation.
Detailed technical explanation
How to think about this question
Under the hood, ISE uses RADIUS attributes (e.g., Tunnel-Private-Group-ID for VLAN assignment and Filter-ID for dACL name) to push policy to the network access device (switch/AP). The dACL is downloaded and installed as a per-user ACL, overriding any interface ACL, and is applied after successful 802.1X or MAB authentication. In a real-world scenario, this allows a single SSID to serve both corporate and guest users, with ISE dynamically steering traffic based on user credentials or device posture.

→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway

Real-world example
How this comes up in practice
A help-desk technician troubleshoots why a newly connected PC cannot reach shared printers on the same floor. The cable is good, the switch port is active, but the PC is in VLAN 20 and the printers are in VLAN 10. The uplink trunk only allows VLAN 10. A trunk being up does not mean every VLAN crosses it.
