Question 1 of 17
1. Question
When setting up Frame Relay for point-to-point subinterfaces, which of the following must not be configured?
Correct
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. Question
Which command will display the CHAP authentication process as it occurs between two routers in the network?
Correct
The command debug ppp authentication will show you the authentication process that PPP uses between point-to-point connections.Incorrect

Question 3 of 17
3. Question
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?
Correct
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.

Question 4 of 17
4. Question
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?
Correct
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. Question
Which WAN encapsulations can be configured on an asynchronous serial connection?
- PPP
- ATM
- HDLC
- SDLC
- Frame Relay
Correct
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. Question
Which encapsulations can be configured on a serial interface?
- Ethernet
- Token Ring
- HDLC
- Frame Relay
- PPP
Correct
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.

Question 7 of 17
7. Question
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?
Correct
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.

Question 10 of 17
10. Question
A default Frame Relay WAN is classified as what type of physical network?
Correct
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.
Incorrect
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.

13. Question
Which of the following uses ATM as the Data Link layer protocol that’s terminated at what’s known as the DSLAM?
Correct
ATM is the Data-Link layer protocol that’s typically used over the DSL layer 1 connection from the CPE and terminated at what’s known as the DSLAM-an ATM switch that contains DSL interface cards, or ATU-Cs.

Question 14 of 17
14. Question
When a router is connected to a Frame Relay WAN link using a serial DTE interface, how is the clock rate determined?
Correct
Clocking on a serial interface is always provided by the CSU/DSU (DCE device). However, if you do not have a CSU/DSU in your nonproduction test environment, then you need to supply clocking with the clock rate command on the serial interface of the router with the DCE cable attached.Incorrect

15. Question
Which command is required for connectivity in a Frame Relay network if Inverse ARP is not operational?
Correct
If you have a router in your Frame Relay network that does not support IARP, you must create Frame Relay maps on your router, which provide known DLCI-to-IP address mappings.

Question 16 of 17
16. Question
How should a router that is being used in a Frame Relay network be configured to keep split horizon issues from preventing routing updates?
Correct
If you have a serial port configured with multiple DLCIs connected to multiple remote sites, split horizon rules, stop route updates received on an interface from being sent out the same interface. By creating subinterfaces for each PVC, you can avoid the split horizon issues when using Frame Relay.
