Guest VLAN
A guest VLAN provides network access for guest devices after registration.
- B
Device sensor
Why wrong: Device sensor is used for profiling, not guest registration.

Sponsor portal
The sponsor portal (or self-registration portal) allows guests to create their own accounts.

350-701 Endpoint Security and Identity Practice Question
This 350-701 practice question tests your understanding of endpoint security and identity. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 security administrator is configuring Cisco ISE for guest access. Which TWO components are required to allow guests to self-register and obtain network access? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Guest VLAN
Guest self-registration requires a sponsor portal (or self-registration portal) and a guest VLAN or restricted ACL to provide limited access initially. The self-registration portal is typically part of the sponsor portal.
Key principle: A trunk being up does not mean the VLAN is allowed across it. Always verify the allowed VLAN list and whether the VLAN exists on both switches.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Guest VLAN
- ✗
Device sensor
Why it's wrong here
Device sensor is used for profiling, not guest registration.
- ✓
Sponsor portal
Why this is correct
The sponsor portal (or self-registration portal) allows guests to create their own accounts.
Related concept
Access ports place end devices into a single VLAN.
- ✗
Posture assessment policy
Why it's wrong here
Posture is typically not applied to guest access.
- ✗
Active Directory integration
Why it's wrong here
AD integration is used for user authentication, not for guest self-registration.
Common exam traps
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.
Detailed technical explanation
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.
Key takeaway
A trunk being up does not mean the VLAN is allowed across it. Always verify the allowed VLAN list and whether the VLAN exists on both switches.
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.
Visual reference
What to study next
Got this wrong? Here's your next step.
Review VLAN allowed lists, native VLAN mismatch detection, and how to verify VLAN membership with show vlan brief and show interfaces trunk. Then practise related 350-701 questions on switching, trunking, and access-port configuration.
