1
When setting up Frame Relay for point-to-point subinterfaces, which of the following must not be configured?
Discuss
Answer & Solution
Answer: Option C
Solution:
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.
2
Which command will display the CHAP authentication process as it occurs between two routers in the network?
Discuss
Answer & Solution
Answer: Option C
Solution:
The command debug ppp authentication will show you the authentication process that PPP uses between point-to-point connections.
3
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?
Discuss
Answer & Solution
Answer: Option D
Solution:
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.
4
You need to configure a router for a Frame Relay connection to a non-Cisco router. Which of the following commands will prepare the WAN interface of the router for this connection?
Discuss
Answer & Solution
Answer: Option C
Solution:
If you have a Cisco router on one side of a Frame Relay network and a non-Cisco router on the other side, you would need to use the Frame Relay encapsulation type of IETF. The default is Cisco encapsulation, which means that a Cisco router must be on both sides of the Frame Relay network.
5
Which WAN encapsulations can be configured on an asynchronous serial connection?
1. PPP
2. ATM
3. HDLC
4. SDLC
5. Frame Relay
Discuss
Answer & Solution
Answer: Option A
Solution:
Please do not freak out because ATM is an answer to this question. ATM is not covered in depth on the CCNA exam. PPP is mostly used for dial-up (async) services, but ATM could be used as well, though it typically is not used anymore since PPP is so efficient.
6
Which encapsulations can be configured on a serial interface?
1. Ethernet
2. Token Ring
3. HDLC
4. Frame Relay
5. PPP
Discuss
Answer & Solution
Answer: Option C
Solution:
Ethernet and Token Ring are LAN technologies and cannot be configured on a serial interface. PPP, HDLC, and Frame Relay are layer 2 WAN technologies that are typically configured on a serial interface.
7
Suppose that you have a customer who has a central HQ and six branch offices. They anticipate adding six more branches in the near future. They wish to implement a WAN technology that will allow the branches to economically connect to HQ and you have no free ports on the HQ router. Which of the following would you recommend?
Discuss
Answer & Solution
Answer: Option C
Solution:
The key is "there are no free ports" on your router. Only Frame Relay can provide a connection to multiple locations with one interface, and in an economical manner no less.
8
Which of the following command options are displayed when you use the Router# show frame-relay ? command?
1. dlci
2. neighbors
3. lmi
4. pvc
5. map
Discuss
Answer & Solution
Answer: Option C
Solution:
The show frame-relay ? command provides many options, but the options available in this question are lmi, pvc, and map.
9
In which of the following technologies is the term HFC used?
Discuss
Answer & Solution
Answer: Option D
Solution:
In a modern network, hybrid fibre-coaxial (HFC) is a telecommunications industry term for a network that incorporates both optical fiber and coaxial cable to create a broadband network.
10
A default Frame Relay WAN is classified as what type of physical network?
Discuss
Answer & Solution
Answer: Option C
Solution:
Frame Relay, by default, is a non-broadcast multi-access (NBMA) network, which means that broadcasts, such as RIP updates, will not be forwarded across the link by default.
