Ex2 after practice exam

Thing to repeat and remeber:

Habits of Highly Effective Students

"What is the best way to study for a Certification Exam?"

This is probably the most common question I get asked by Network Academy  students and peers chasing Cisco Certifications. While there is no concrete answer that works for everyone, there are some really great pieces of advice that I have heard throughout the years, and implemented in my daily study routine.

Ex2 Chapter 12 – BGP basics

The Border Gateway Protocol (BGP) is the core routing protocol of the Internet. It maintains a table of IP networks or 'prefixes' which designate network reachability among autonomous systems (AS). It is described as a path vector protocol. BGP does not use traditional Interior Gateway Protocol (IGP) metrics, but makes routing decisions based on path, network policies and/or rulesets.

Routers use “routing protocols” to exchange routing information with each other.

Ex2 Chapter 10 – Link-State Routing Protocols

Distance vector routing protocols are like road signs because routers must make preferred path decisions based on a distance or metric to a network.
Link-state routing protocols take a different approach. Link-state routing protocols are more like a road map because they create a topological map of the network and each router uses this map to determine the shortest path to each network.
