ITN Chapter 6 TEST Study Guide
Why is NAT not needed in IPv6?
Any host or user can get a public IPv6 network address because the number of available IPv6 addresses is extremely large.
Which of the following are characteristics of IP?
Best Effort Connectionless Media Independent.
When configuring a host, the gateway was not configured. How will this effect communication to and from this device?
Communication will be limited to hosts in the local network.
What are the required steps for configuring an interface on a router?
Configure the router's device name Secure the user EXEC mode Secure remote Telnet and SSH access Secure privileged EXEC mode Secure all passwords in the config file Provide legal notification - Authorized access only Save the configuration OR Activate the interface Provide Layer 3 addressing information.
When using the netstat -r command on a host, you see a route 0.0.0.0 0.0.0.0.0. What does this route represent?
Destinations without a specified route are forwarded to the gateway.
The ip default-gateway command was not used when configuring a switch, how will this affect network communication?

Routing Table ARP Cache
Which two files if found are copied into RAM as a router with the default configuration register setting bootup?
Startup Configuration IOS Image File
During the process of forwarding traffic what will the router do immediately after matching the destination IP address to a network on a directly connected routing table entry?
Switch the packet to the directly connected interface.
On a router what field in an IPv4 header should be examined to determine the maximum number of hops have been reached by the packet on its way from the source to its destination?
TTL/Time-to-Live
How do hosts insure that their packets are directed to the direct network destination?
They must keep their own local routing table that contains a route to the loopback interface a local network route and remote default route.
Which two commands can be used on a windows host to display the routing table?
route print netstat -r
Which IOS command displays contents of the IPv4 routing table stored in RAM?
