What multicast addresses does RIPng use?
Your Answer : (Not Answered)
Correct Answer : B
RIPng uses the multicast IPv6 address of FF02::9. If you remember the multicast addresses for IPv4, the numbers at the end of each IPv6 address are the same.
Which of the following are disadvantages of using NAT?
1.Translation introduces switching path delays.
2.Conserves legally registered addresses.
3.Causes loss of end-to-end IP traceability.
4.Increases flexibility when connecting to the Internet.
5.Certain applications will not function with NAT enabled.
6.Reduces address overlap occurrence.
Your Answer : (Not Answered)
Correct Answer : A
NAT is not perfect and can cause some issues in some networks, but most networks work just fine. NAT can cause delays and troubleshooting problems, and some applications just won't work.
Which of the following is considered to be the address before translation?
Your Answer : (Not Answered)
Correct Answer : A
The host on the private network before translation is considered to be an inside local host.
Which command would you place on interface on a private network?
Your Answer : (Not Answered)
Correct Answer : A
As in access-lists, you must configure your interfaces before NAT will provide any translations. On the inside networks you would use the command ip nat inside. On the outside interface, you will use the command ip nat outside.
Which of the following commands sets a trunk port on a 2960 switch?
Your Answer : (Not Answered)
Correct Answer : D
To set a switch port to trunk mode, which allows all VLAN information to pass down the link, use the switchport mode trunk command.
You get a call from a network administrator who tells you that he typed the following into his router:
Router(config)#router ospf 1
Router(config-router)#network 10.0.0.0 255.0.0.0 area 0
He tells you he still can't see any routes in the routing table. What configuration error did the administrator make?
Your Answer : (Not Answered)
Correct Answer : A
The administrator typed in the wrong wildcard mask configuration. The wildcard should have been 0.0.0.255.
Your company is running IGRP using an AS of 10. You want to configure EIGRP on the network but want to migrate slowly to EIGRP and don't want to configure redistribution. What command would allow you to migrate over time to EIGRP without configuring redistribution?
Your Answer : (Not Answered)
Correct Answer : B
If you enable EIGRP on a router with the same autonomous system (AS) number, EIGRP will automatically redistribute IGRP into EIGRP. You will see the IGRP injected routes as external (EX) routes with an EIGRP AD of 170. This is a nice feature that lets you migrate slowly to EIGRP with no extra configuration.

2.A rollover cable should be used in place of the straight-through cable.
3.The subnet masks should be set to 255.255.255.192.
4.A default gateway needs to be set on each host.
5.The subnet masks should be set to 255.255.255.0.
Your Answer : (Not Answered)
Correct Answer : D
First, if you have two hosts directly connected, as shown in the graphic, then you need a crossover cable. A straight-through cable won't work. Second, the hosts have different masks, which puts them in different subnets. The easy solution is just to set both masks to 255.255.255.0 (/24).
The Acme Corporation is implementing dial-up services to enable remote-office employees to connect to the local network. The company uses multiple routed protocols, needs authentication of users connecting to the network, and since some calls will be long distance, needs callback support. Which of the following protocols is the best choice for these remote services?
Your Answer : (Not Answered)
Correct Answer : D
PPP is your only option, as HDLC and Frame Relay do not support these types of business requirements. PPP provides dynamic addressing, authentication using PAP or CHAP, and callback services.
When setting up Frame Relay for point-to-point subinterfaces, which of the following must not be configured?
Your Answer : (Not Answered)
Correct Answer : C
It is very important to remember when studying the CCNA exam objectives, and when configuring Frame Relay with point-to-point subinterfaces, that you do not put an IP address on the physical interface.
What is the maximum distance running the lowest data rate for 802.11g?

What is the maximum distance running the lowest data rate for 802.11a?
Your Answer : (Not Answered)
Correct Answer : B
The IEEE 802.11a standard's lowest data rate is 6Mbps, but it can run from a distance of about 175 feet.
What is the maximum distance with maximum data rate for 802.11b?
Your Answer : (Not Answered)
Correct Answer : C
The IEEE 802.11b standard provides a maximum data rate of up to only 11Mbps, and you can be around 150 feet, maybe farther, depending on conditions.
Which command would you use to apply an access list to a router interface?

The (config-router)#passive-interface command stops updates from being sent out an interface, but route updates are still received.
You want to totally reinitialize the router and replace the current running-config with the current startup-config. What command will you use?
Your Answer : (Not Answered)
Correct Answer : C
To completely replace the running-config with the startup-config, you must reload the router. Note : You may have picked option C, which isn't a bad answer. Remember, though, it doesn't replace the configuration, it appends it.
You need to find the broadcast address used on a LAN on your router. What command will you type into the router from user mode to find the broadcast address?
Your Answer : (Not Answered)
Correct Answer : C
The command show ip protocols will actually show you the broadcast address for each interface - too bad it isn't a possible answer. Your best answer is show interfaces, which will provide the IP address and mask for each interface.
