1. What is the best route summarization for the following list of networks?

209.48.200.0
209.48.201.0
209.48.202.0
209.48.203.0
>> 209.48.200.0/22

1. Given a host with the IP address 172.32.65.13 and a default subnet mask, to which network does the host belong?

>> 172.32.0.0

1. A class of C network address has been subnetted into eight subnetworks. Using VLSM, the last subnet will be divided into eight smaller subnetworks. What bit mask must be used to create eight smaller subnetworks, each having two usable host addresses?

>> /30

1. Which address is a valid subnet if a 26 bit mask is used for subnetting?

>> 172.16.243.64

1. Refer to the exhibit. A network technician is trying to determine the correct IP address configuration for Host A. what is a valid configuration for Host A?

>> IP address: 192.168.100.20; subnet mask: 255.255.255.240; default gateway: 192.168.100.17

1. What is true regarding the differences between NAT and PAT?

>> PAT uses unique source port numbers to distinguish between translations

1. Match each characteristic on the left to the corresponding NAT technique on the right

>> Dynamic NAT
Assigns the translated addresses of IP hosts from a pool of public addresses
Defines translations on a host-to-host basis
>> NAT with Overload
Can map multiple addresses to a single address of the external interface
Assigns unique source port numbers of an inside global address on a session-by-session basis
>> Static NAT
Allows external hosts to establish sessions with an internal host
Provides one-to-one fixed mappings of local and global addresses

1. Refer to the exhibit. Which address is an inside global address?

>> 209. 13. 24. 3

1. Refer to the exhibit. The command show ip nat translations has been issued. Which type of NAT translation is being performed?

>> NAT overloading configuration

1. What is the purpose of a subnet mask in a network?

>> a subnet mask is used to identify the network portion of IP address

1. How many addresses will be available for dynamic NAT translation when a router is configured with the following commands?
