21. In a network with dozens of switches, how many root bridges would you have?
- 1
- 2
- 5
- 12
22. What PPP protocol provides dynamic addressing, authentication, and multilink?
- NCP
- HDLC
- LCP
- X.25
23. What is a stub network?
- A network with more than one exit point.
- A network with more than one exit and entry point.
- A network with only one entry and no exit point.
- A network that has only one entry and exit point.
24. If your router is facilitating a CSU/DSU, which of the following commands do you need to use to provide the router with a 64000bps serial link?
- RouterA(config)#bandwidth 64
- RouterA(config-if)#bandwidth 64000
- RouterA(config-if)#clock rate 64
- RouterA(config-if)#clock rate 64000
25. Which one of the following is true regarding VLANs?
- Two VLANs are configured by default on all Cisco switches.
- VLANs only work if you have a complete Cisco switched internetwork. No off-brand switches are allowed.
- You should not have more than 10 switches in the same VTP domain.
- VTP is used to send VLAN information to switches in a configured VTP domain.
26. What does a VLAN do?
- Acts as the fastest port to all servers.
- Provides multiple collision domains on one switch port.
- Breaks up broadcast domains in a layer 2 switch internetwork.
- Provides multiple broadcast domains within a single collision domain.
27. What is the main reason the OSI model was created?
- To create a layered model larger than the DoD model.
- So application developers can change only one layer's protocols at a time.
- So different networks could communicate.
- So Cisco could use the model.
28. How many collision domains are created when you segment a network with a 12-port switch?
- 1
- 2
- 5
- 12
29. What command will display the line, protocol, DLCI, and LMI information of an interface?
- sh pvc
- show interface
- show frame-relay pvc
- show run
