How does Rapid PVST+ create a fast loop-free network topology? A. lt requires multiple links between core switches B. It generates one spanning-tree instance for each VLAN C. It maps multiple VLANs into the same spanning-tree instance D. It uses multiple active paths between end stations. Refer to the exhibit. Which command configures OSPF on the point-to-point link between routers R1 and R2? A. router-id 10.0.0.15 B. neighbor 10.1.2.0 cost 180 C. network 10.0.0.0 0.0.0.255 area 0 D. ip ospf priority 100. A network engineer must implement an IPv6 configuration on the vlan 2000 interface to create a routable locally-unique unicast address that is blocked from being advertised to the internet. Which configuration must the engineer apply? A.
