What are the fundamental differences between a router and a switch?
Router operates at Layer 3 and uses IP/AT/IPX. Creates broadcast domains.

Switch operates at layer 2 and uses MAC address. Creats collision domains.
What are the major functions of a router?
To relay a packet, the router uses two basic functions: a path determination function and a switching function.
What does a switch use to make forwarding decisions?
A switch uses MAC addresses.
What does a switch do if it can't determine where to send a frame?
It floods the network (except from the port that sending the frame)
What is the differences between a broadcast domain and a collision domain?
Broadcast domain is divided by routers. A collision domain is divided up by switches.
How is a broadcast domain created?
Broadcast domain is divided by routers.
How is a collision domain created?
A collision domain is divided up by switches.
Name four common TCP/IP services and the default ports they use?
HTTP 80
FTP 21/20
DNS 53
SMTP 25
POP 110
IMAP 143
SSL 443
Name the Distance Vector Protocols?
RIP and IGRP
Name the Link State Protocols?
OSPF and IS-IS
What are the differences between Distance Vector and Link State protocols?
Distance Vector has nonspecific information about distant networks and no knowledge of distant routers. Link state maintains full knowledge of distant routers. Distant vector gets information from neighbors, link state gets information from link state advertisements.
What is the difference between a routed and routable protocol?
Routed protocol provides enough information in its network layer address to allow a packet to be forwarded from host to host based on addressing scheme. IP is an example of a routed protocol.

A routing protocol is a protocol that supports a routed protocol by providing mechanisms for sharing routing information. Routing protocol messages move between routers. Examples: RIP, IGRP, EIGRP & OSPF.
What does the configuration register set to 0x2102 signify?
Boots to NVRAM
What is the router boot sequence for a cisco router?
Bootstrap, locate and load o.s., load configuration file.

ROM, (FLASH, TFTP Server, ROM), (NVRAM, TFTP SERVER, CONSOLE)
Where are standard access lists placed?
Close to the destination
