Q92. CORRECT TEXT - (Topic 7)
A network associate is configuring a router for the weaver company to provide internet access. The ISP has provided the company six public IP addresses of 198.18.184.105
198.18.184.110. The company has 14 hosts that need to access the internet simultaneously. The hosts in the company LAN have been assigned private space addresses in the range of 192.168.100.17 – 192.168.100.30.
Answer: The company has 14 hosts that need to access the internet simultaneously but
we just have 6 public IP addresses from 198.18.184.105 to 198.18.184.110/29.
Therefore we have to use NAT overload (or PAT)
Double click on the Weaver router to open it
Router>enable Router#configure terminal
First you should change the router's name to Weaver
Router(config)#hostname Weaver
Create a NAT pool of global addresses to be allocated with their netmask.
Weaver(config)#ip nat pool mypool 198.18.184.105 198.18.184.110 netmask 255.255.255.248
Create a standard access control list that permits the addresses that are to be translated
Weaver(config)#access-list 1 permit 192.168.100.16 0.0.0.15
Establish dynamic source translation, specifying the access list that was defined in the prior step
Weaver(config)#ip nat inside source list 1 pool mypool overload
This command translates all source addresses that pass access list 1, which means a source address from 192.168.100.17 to 192.168.100.30, into an address from the pool named mypool (the pool contains addresses from
198.18.184.105 to 198.18.184.110) Overload keyword allows to map multiple IP addresses to a single registered IP address (many-to-one) by using different ports The question said that appropriate interfaces have been configured for NAT inside and NAT outside statements. This is how to configure the NAT inside and NAT outside, just for your understanding:
Weaver(config)#interface fa0/0 Weaver(config-if)#ip nat inside Weaver(config-if)#exit Weaver(config)#interface s0/0 Weaver(config-if)#ip nat outside Weaver(config-if)#end
Finally, we should save all your work with the following command:
Weaver#copy running-config startup-config
Check your configuration by going to "Host for testing" and type:
C :\>ping 192.0.2.114
The ping should work well and you will be replied from 192.0.2.114

Q95. - (Topic 9)
What is the effect of the overload keyword in a static NAT translation configuration?
A. It enables port address translation.
B. It enables the use of a secondary pool of IP addresses when the first pool is depleted.
C. It enables the inside interface to receive traffic.
D. It enables the outside interface to forward traffic.
Answer: A

Q96. - (Topic 1)
Host 1 is trying to communicate with Host 2. The e0 interface on Router C is down.
Which of the following are true? (Choose two.)

B. Router C will use ICMP to inform Router B that Host 2 cannot be reached.
C. Router C will use ICMP to inform Host 1, Router A, and Router B that Host 2 cannot be reached.
D. Router C will send a Destination Unreachable message type.
E. Router C will send a Router Selection message type.
F. Router C will send a Source Quench message type.
Answer: A,D
