It is automatically updated and maintained by routing protocols.
It is unaffected by changes in the topology of the network.
It has an administrative distance of 1.
It is identified by the prefix C in the routing table.
They improve network security.
They use fewer router resources.
They improve the efficiency of discovering neighboring networks.
They take less time to converge when the network topology changes.
They automatically switch the path to the destination network when the topology changes.
RIPv2 does not support VLSM.
RIPv2 is misconfigured on router R1.
RIPv2 is misconfigured on router R2.
RIPv2 is misconfigured on router R3.

Level 2 child route
Speed of convergence
The autonomous system that is used
Campus backbone architecture
Aggregates Layer 2 broadcast domains
Aggregates Layer 3 routing boundaries
Provides access to the user
Provides fault isolation
Drop the frame.
Send the frame to the default gateway address.
Use ARP to resolve the port that is related to the frame.
Forward the frame out all ports except the port where the frame is received.
Frame error checking
Faster frame forwarding
Frame forwarding using IPv4 Layer 3 and 4 information
Ingress port buffering
When the Layer 2 switch needs to forward user traffic to another device
When the Layer 2 switch is the default gateway of user traffic
When the Layer 2 switch needs to be remotely managed
When the Layer 2 switch is using a routed port
Auto secure MAC addresses
Dynamic secure MAC addresses
Static secure MAC addresses
Sticky secure MAC addresses
Another switch was connected to this switch port with the wrong cable.
An unauthorized user tried to telnet to the switch through switch port Fa0/8.
NAT was enabled on a router, and a private IP address arrived on switch port Fa0/8.
A host with an invalid IP address was connected to a switch port that was previously unused.
Port security was enabled on the switch port, and an unauthorized connection was made on switch port Fa0/8.
They are numbered VLANs 1002 to 1005.
They cannot be used across multiple switches.
They are reserved to support Token Ring VLANs.
They are not stored in the vlan.dat file.
