The access list permits or denies specific addresses from entering the device doing the translation.

11

Which two characteristics describe the native VLAN? (Choose two.)

Designed to carry traffic that is generated by users, this type of VLAN is also known as the default VLAN.
High priority traffic, such as voice traffic, uses the native VLAN.
This VLAN is necessary for remote management of a switch.
The native VLAN provides a common identifier to both ends of a trunk./The native VLAN traffic will be untagged across the trunk link.

Efer 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

SW-A will remove the outer tag and send the rest of the frame across the trunk link, where SW-B will forward the frame to hosts on VLAN 12.
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 drop the frame because it is invalid.

OSPFv3 routers use a different metric than OSPFv2 routers use.
OSPFv3 routers do not need to elect a DR on multiaccess segments.
OSPFv3 routers do not need to have matching subnets to form neighbor adjacencies.
