World of Computer Networking Your CCNA start - Summary "Routing"

The video tutorial covers routers and routing, explaining how routers build routing tables and make independent routing decisions. It discusses static and dynamic routes, default routes, and dynamic routing protocols like OSPF and BGP. The tutorial also explores autonomous systems, routing protocol metrics, and the process of end-to-end transmission, including the use of traceroute utilities.

What layer of the TCP model do routers operate on?

• Network Layer

• Transport Layer

• Data Link Layer

• Application Layer

What is a key characteristic of how routers make routing decisions?

• They rely on a central server

• They make decisions independently

• They follow the shortest path only

• They use a fixed path

What action do routers perform on data link layer headers during routing?

• Compress them

• Ignore them

• Encrypt them

• Remove and add new headers

How are static routes added to a routing table?

• Through a dynamic protocol

• Via a default setting

• Automatically by the router

• By a network administrator

What is a default route often referred to as?

• Last resort route

• Backup route

• Primary route

• First choice route

Which of the following is a popular dynamic routing protocol?

• OSPF

• SMTP

• FTP

• HTTP

What does CIDR allow routers to do?

• Ignore subnetting

• Stick to classful addressing

• Use default masks only

• Use variable-length subnet masks

What is an autonomous system in networking?

• A network without IP addresses

• A single router

• A type of routing protocol

• A large network with a unique number

What is the main difference between IGP and EGP protocols?

• EGP is more secure than IGP

• IGP is for public routes, EGP is for private routes

• IGP works within an autonomous system, EGP works between them

• IGP is faster than EGP

What is a key feature of link state routing protocols?

• They are more sophisticated

• They rely on neighbor information

• They use hop count as a metric

• They require less memory
