Refer to the exhibit. The Branch Router has an OSPF neighbor relationship with the HQ router over the 198.51.0.4/30 network. The 198.51.0.8/30 network link should serve as a backup when the OSPF link goes down. The floating static route command ip route 0.0.0.0 0.0.0.0 S0/1/1 100 was
issued on Branch and now traffic is using the backup link even when the OSPF
link is up and functioning. Which change should be made to the static route
command so that traffic will only use the OSPF link when it is up?
Add the next hop neighbor address of 198.51.0.8.
Change the administrative distance to 1.
Change the destination network to 198.51.0.5.
Change the administrative distance to 120.
Change the administrative distance to 120.

Refer to the exhibit. An attacker on PC X sends a frame with two 802.1Q tags on it, one for VLAN 40 and another for VLAN 12.
What will happen to this frame?
SW-A will drop the frame because it is invalid.
SW-A will leave both tags on the frame and send it to SW-B, which will forward it to hosts on VLAN 40.
SW-A will remove both tags and forward the
rest of the frame across the trunk link, where
SW-B will forward the frame to
hosts on VLAN 40.
SW-A will remove the outer tag and send the rest of the frame across the trunklink, where SW-B will forward the frame to hosts on VLAN 12.
SW-A will remove both tags and forward therest of the frame across the trunk link, where SW-B will forward the frame tohosts on VLAN 40.
