Free Juniper JN0-460 Actual Exam Questions - Question 12 Discussion

B/D? I’m guessing it’s either the AP or the switch since those handle VLANs directly, but APs sometimes miss VLAN tags which can cause this too. Not sure if it points to one more than the other here.

Option D, switches are usually responsible for VLAN configs, not clients or gateways.

This notification typically means the switch doesn't have the VLAN configured, so I’d say D. The switch manages VLANs more directly than APs or clients. D

The alert usually points to the switch missing the VLAN, so D.

Guessing D since switches handle VLAN tagging and distribution mostly.

Maybe B, since if the AP isn’t tagged with the VLAN, it won’t pass traffic correctly.

D/B? The notification says "Missing VLAN," which makes me think it’s more about where VLANs are actually configured and passed through—so switches seem like the most logical place. Gateways usually route traffic but don’t handle VLAN tagging themselves, and access points just bridge the VLANs they get from the switch. If a switch doesn’t have the VLAN set up, devices won’t see it at all, which fits the alert better than a client or AP missing it.

It’s A. The gateway missing the VLAN would cause the whole segment to lose connectivity for that VLAN, triggering an alert like this. If just an AP or client was missing it, the issue would be more localized and probably wouldn’t raise a Marvis action. Switches usually have the VLAN configured if the gateway does, since they rely on it upstream. So the root of the problem is likely at the gateway level.

Probably D since switches handle VLAN assignments directly, so missing VLAN there causes issues.

B makes the most sense here since GBP tags based on endpoint type help isolate traffic effectively within the same VRF. Assigning by location or individually would be less efficient.
