VLAN Ports JN0-352 Practice Questions (Page 2)
Part of the Layer 2 Switching and VLANs domain, which makes up ~15% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~5–9 in this domain), expect 1–1 from this objective — we provide 14 practice questions to prepare you well beyond it.

An administrator is troubleshooting a connectivity issue between two switches connected by a trunk port. The trunk port on Switch A is configured with `native-vlan-id 10` and `vlan members [10 20 30]`. The trunk port on Switch B is configured with `native-vlan-id 20` and `vlan members [10 20 30]`. Devices in VLAN 10 cannot communicate across the trunk, but devices in VLANs 20 and 30 can. What is the most likely cause?

An administrator is connecting a new device to an access port on an EX switch. The device is a legacy printer that sends untagged frames. The administrator configures the port as an access port in VLAN 10. After connecting the printer, the administrator runs `show ethernet-switching interface ge-0/0/4` and sees the port is in VLAN 10 and is up. However, the printer cannot be reached from other devices in VLAN 10. The administrator runs `show ethernet-switching table vlan 10` and does not see the printer's MAC address. What is the most likely cause?

An administrator is verifying the configuration of a switch port that should be an access port in VLAN 10. The administrator runs `show ethernet-switching interface ge-0/0/3` and sees the following output: `ge-0/0/3.0` is in VLAN 10, and the port is up. However, a host connected to this port cannot reach other devices in VLAN 10. What additional command should the administrator run to verify the port is actually an access port?

A switch trunk port connects to a third-party router that sends untagged frames for the management VLAN (VLAN 5) and tagged frames for VLANs 100 and 200. The Junos switch is configured with `native-vlan-id 5` and `vlan members [5 100 200]`. The management interface on the router is reachable, but devices in VLAN 100 cannot communicate through the router. What is the most likely cause?
