Full question →mediummultiple choiceObjective-mapped
A monthly vulnerability scan identifies a critical vulnerability on a public-facing VPN appliance, but the vendor says no patch is available yet. The service must remain online for remote workers. What is the best compensating control to reduce risk right away?
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
Ignore the finding until the next quarterly review because there is no patch available.
Risk remains high, and deferring action leaves the exposed system unprotected longer.
B
Distractor review
Move the appliance to a less critical VLAN and leave all access rules unchanged.
Changing VLANs alone does not reduce attack exposure if the service is still broadly reachable.
C
Best answer
Apply virtual patching or traffic filtering to block exploit attempts until remediation is possible.
Filtering malicious traffic is a practical compensating control when a permanent fix is not yet available.
D
Distractor review
Disable logging so that attackers cannot learn the appliance version from log data.
Disabling logs reduces visibility and makes incident response harder without addressing the vulnerability.
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: Apply virtual patching or traffic filtering to block exploit attempts until remediation is possible. — When a patch is unavailable, the best immediate step is a compensating control such as virtual patching through IPS or targeted traffic filtering. This reduces exposure to known exploit patterns while the organization plans a vendor fix, replacement, or maintenance window. Because the appliance must remain online, the goal is to lower likelihood without interrupting business access. That is the most practical short-term risk reduction. Why others are wrong: Ignoring the issue leaves a critical internet-facing vulnerability exposed. Reassigning the appliance to another VLAN does not help unless access is also restricted. Disabling logging is counterproductive because it reduces detection and investigation capability while doing nothing to block exploitation attempts.
