1. Which OSI Reference Layer is concerned with path determination?
Network
2. What is the default LMI type for Cisco Routers that are using Frame-Relay?
Cisco
3. The Internet Control Message Protocol occurs at what layer of the seven layer model?
Network
4. Which protocol resolves an IP address to a MAC address?
ARP
5. In regards to the ISDN BRI standard, which channel is used for control?
B
6. On an ISDN BRI interface, the control channel is the ‘D’ channel. What is the rate of this channel?
16 Kbps
7. What is the administrative distance for IGRP?
100
8. The benefits to segmenting with Bridges are which of the following?
Datagram filtering
9. Bridges work at what layer of the OSI model?
Data link
10. What is the default switching method for the Cisco 5000 series?
Store-and-forward
11. You have two Cisco routers setup back-to-back in a lab using DTE/DCE cables. To which router would you add the clockrate command?
The serial port on the DCE router
12. What is the protocol number for UDP?
17
13. Which layer is responsible for coordinating communication between systems?
Session
14. Which protocol will send a message to routers if a network outage or congestion occurs?
ICMP
15. When would you use ISDN?
To support applications requiring voice, data, and video
16. Which layer defines bit synchronization?
Physical
17. Which layer is responsible for synchronizing sending and receiving applications?
Session
18. Which protocol is used for booting diskless workstations?
RARP
19. What does a router do with a packet that it does not have a destination network for?
Drops the packet
20. What is the default interval for SAP updates?
60 seconds
21. Which command will display the CHAP authentication process as it occurs between two routers in the network?
debug ppp authentication
22. Which command is required for connectivity in a Frame Relay network if Inverse ARP is not operational?
frame-relay map
23. 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?
Frame Relay
24. How should a router that is being used in a Frame Relay network be configured to keep split horizon issues from preventing routing updates?
Configure a separate subinterface for each PVC with a unique DLCI and subnet assigned to the subinterface.
25. 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?
Router(config-if)#encapsulation frame-relay ietf
26. 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?
PPP
27. Which WAN encapsulations can be configured on an asynchronous serial connection?
ATM
28. Which of the following uses ATM as the Data Link layer protocol that’s terminated at what’s known as the DSLAM?
DSL
29. What two statements about IPv4 and IPv6 addresses are true?
An IPv4 address is 32 bits long, represented in decimal.
30. Which WAN encapsulations can be configured on an asynchronous serial connection?
Router1(config-if)# ipv6 ospf 10 area 0.0.0.0
