What does a router connect? What does a router do with each packet it receives? What are the 2 types of connections to a router interface? What are the two primary functions of a router? What address does the router use to compare to the routing table? What two processes are used by a router to learn about remote networks and build their routing tables? What are the five components common to all routers? List the 5 different components stored in RAM. What happens to the information in RAM if the router looses power? What are the permanent storage areas in a router? What 3 things are stored in ROM? What is stored in flash? What happens to flash memory when the power is lost? What is stored in NVRAM? What must you do to save changes you have made to a router? What is the most common method used for configuring a router? What is the first thing that happens as the router boots up? What are the 4 phases of the bootup process? 22.214.171.124 1.1.5 126.96.36.199 1.1.6 188.8.131.52 1.2.1 What does POST test? What is the main function of the bootstrap program? What are the 2 main places to find the IOS? If a full IOS can not be loaded what does the bootstrap loader do? Where is the startup configuration found? What are the main items stored in the configuration file? Where is the second place that the router looks for the startup config if it is not located in NVRAM? If the router can not locate a startup-config, what mode does it enter? What key command do you press to exit setup mode if you accidentally entered it? What command can be used to help verify and troubleshoot some of the basic hardware and software components of the router? What is the last line displayed in the show version output? What is the default configuration register setting? What does that setting tell the router? What are the two management ports? What is an interface? What must be configured for each interface? What are the two major groups of router interfaces? What OSI layer does a router operate at? What is the router interface that connects to a LAN called? What is the process that each router uses to determine where to send the packet? What are the four essential information elements to include 1.2.2 184.108.40.206 220.127.116.11 in the topology diagram? What are the basic tasks to perform when configuring a router? What is the prompt for the user mode? What is the command to enter the privileged EXEC mode? What is the prompt for privileged EXEC mode? What is the command to enter the global configuration mode? What is the command to enter the hostname of a router? What happens to the prompt after you press enter? What is the command used to enter the password to enter the privileged EXEC mode? List the commands to set the password for the console port? List the commands to set the password for the Telnet lines? List the commands to enter the Banner Message of the Day (motd). What should the banner show? What is the command to enter the interface configuration mode? What is the command to set the IP address and subnet mask for an interface? What is the command to enter a description for the interface? What is the command to turn on an interface? What is the command to view the running-configuration file? What is the command to save the current config in NVRAM? What command will display the routing table? What command displays all of the interface configuration parameters and statistics? What command displays abbreviated interface configuration information, 1.3.1 18.104.22.168 1.3.3 1.3.4 1.3.5 1.4.2 including IP address and interface status? Where is the routing table stored? What is a directly connected network? What is a remote network? What would a C in the first column of a routing table mean? What additional information is included when the destination is a remote network? What command reveals the configured or acquired default gateway, connected, loopback, multicast, and broadcast networks? How does a PC determine which network it belongs to? What command will activate a router interface? What routes does a router know before any static or dynamic routing is configured? What denotes a static route in the routing table? What are the three items that must be included in a static route? When should static routes be used? What are dynamic routing protocols used for? What are 2 of the activities that dynamic routing protocols perform? What is network discovery? What are some dynamic routing protocols? What are the three routing principles? What is asymmetric routing? What does a router compare to select the best path to place in the routing table? What is a metric? What is the best path? The number of routers that a 1.4.3 1.4.4 1.4.5 22.214.171.124 1.5.2-4 packet must travel through before reaching its destination is called? The data capacity of a link, sometimes referred to as the speed of the link? What is it called when two paths to a destination have exactly the same metric? What is equal cost load balancing? What are the two functions of packet forwarding? What is the process used by a router to accept a packet on one interface and forward it out another interface called? What are the three major steps a router performs on a packet? What happens to the value of the TTL as a packet moves through a network? Which address does not change as the packet moves through the network? Which address changes as the packet moves through the network? How does a PC determine which network it belongs to? How does it determine if the destination is on the same network? Where does the PC send the packet if the destination is not on its own network? Where does the PC look for the default gateway MAC address? What does the PC do if the MAC address is not in the ARP table? Excellent description of how a packet travels from one pc to another. Make certain you understand the steps. Note any questions you have about the process.
