The one with the longest matching prefix
What is the 80/20 rule state?
80 percent of traffic should be local to the LAN or VLAN, only 20 percent should cross broadcast domains
VLANs define what kind of domain?
Broadcast domain
To support discontiguous subnets. what type of routing protocol is required?
One that supports classless routing
What Cisco technology can be implemented to eliminate a single point of failure at the router?
HSRP - Hot standby router protocol

Which Cisco technology is a scalable, multi-enterprise solution for multicast?
PIM - Protocol Independent Multicast
Where does RIP v1 and IGRP perform route summarization?
At major classful boundaries
What are two key benefits of route summarization?
Reduces memory usage in the router and reduces network traffic

Seconday addresses
At which tier of the hierarchical model is QoS usually deployed?
Core layer
Which tier of the hierarchical model usually contain the campus backbone routers?

Do RIP v1 and IGRP advertise subnet masks?
No, they are classful routing protocols
What is the decimal range of a Class A address?
0 to 126 (127 is the loopback address)

Collapsed backbone
What are the two basic types of backbones?
Distrributed and Collapsed
What are the three requirements to use route summarization?
(1) IP addresses must share the same high order bits (2) routing decisions must be based on a 32 bit address (3) routing protocols must carry the subnet mask
In 10Base-2 cabling, at what distance are repeaters necessary?
185 meters or greater
What technology combines routing and switching in a single box and caches flows?
Multilayer switching
What is a widely deployed high-speed upgrade path for existing legacy FDDI distributed backbones?
