A switch receives a tagged frame on a trunk port with VLAN ID 10. The ingress port is configured with a native VLAN of 10. How does the switch process the frame?

It strips the tag and processes the frame as untagged in the native VLAN.

It assigns the frame to the native VLAN and ignores the tag.

It drops the frame because the tag matches the native VLAN.

It processes the frame as belonging to VLAN 10, using the tag in the frame.

When a switch receives a frame on an access port, which two actions are performed during ingress processing?

The switch floods the frame out all ports in the VLAN and then learns the source MAC address.

The switch checks the destination MAC address against the MAC address table and then learns the source MAC address.

The switch removes the 802.1Q tag and then performs a destination MAC lookup.

The switch learns the source MAC address and associates it with the ingress port and the port's configured VLAN.

Which action is performed by a switch during egress processing when a frame is destined for a known unicast MAC address?

The switch floods the frame out all ports in the VLAN.

The switch sends the frame to the CPU for processing.

The switch forwards the frame only out the port associated with the destination MAC address.

The switch drops the frame because unicast frames are not forwarded.

Which action describes filtering a frame based on VLAN membership?

The switch forwards a frame out all ports regardless of VLAN membership.

The switch drops a frame that arrives on a port that is not a member of the frame's VLAN.

The switch removes the VLAN tag from a frame before forwarding it on a trunk port.

The switch learns the source MAC address and associates it with the VLAN.

When a frame is forwarded out an access port, what does the switch do with the 802.1Q tag?

It replaces the tag with a new VLAN ID.

Part of the Layer 2 Bridging and VLANs domain, which makes up ~11% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–7 in this domain), expect 1–1 from this objective — we provide 15 practice questions to prepare you well beyond it.
