What happens to a tagged frame when it is forwarded out an access port?

The tag is removed before the frame is sent

The tag is replaced with the access port's VLAN ID

The tag is kept to preserve VLAN information

The frame is dropped because access ports cannot receive tagged frames

How does VLAN tagging enable multiple VLANs to traverse a single trunk link?

By embedding a VLAN identifier in each frame so switches can demultiplex them

By assigning each VLAN a different physical cable

By using IP addresses to separate VLAN traffic

By time-division multiplexing frames from different VLANs

Two Juniper switches are connected via a trunk link. Switch A has native VLAN 10, and Switch B has native VLAN 20. Both switches have VLANs 10 and 20 configured. What is the most likely result of this configuration?

All traffic between the switches will be dropped.

Tagged frames for VLAN 10 will be stripped and forwarded untagged on Switch B.

Untagged frames sent from Switch A will be received on Switch B as VLAN 20, causing potential misrouting.

The trunk link will automatically adjust the native VLAN to match.

What is the native VLAN on a trunk port?

The VLAN that carries untagged frames on the trunk

The VLAN that receives the highest priority for forwarding

The VLAN that is automatically created on all switches

The VLAN that is used for management traffic only

VLAN Tagging JN0-281 Practice Questions (Page 2)

Part of the Layer 2 Switching and VLANs domain, which makes up ~21% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~7–13 in this domain), expect 1–2 from this objective — we provide 20 practice questions to prepare you well beyond it.
