|---|---|---|---|
| What VTP mode can only accept VLAN information and not change it? | 1. Client | ||
| What VLAN identification method is proprietary to Cisco routers? | 2. Inter-Switch Link (ISL) | ||
| Switches, by default, only break up ________ domains. | 4. Collision | ||
| What is the default VTP mode? | 5. Server | ||
| What does trunking provide? | 6. Trunking allows you to make a single port part of multiple VLANs at the same time. | ||
| What is frame tagging? | 7. Frame identification (frame tagging) uniquely assigns a user-defined ID to each frame. This is sometimes referred to as a VLAN ID or color. | ||
| True/False: The ISL encapsulation is removed from the frame if the frame is forwarded out an access link. | 8. True | ||
| What type of link is only part of one VLAN and is referred to as the “native VLAN” of the port? | 9. Access link | ||
| What type of Cisco tagging information allows VLANs to be multiplexed over a trunk link through an external encapsulation method? | 10. Inter-Switch Link (ISL) | ||
| Which of the following is true regarding VLANs? | Switches do not propagate VLAN information by default; you must configure the VTP domain. VLAN Trunk Protocol (VTP) is used to propagate VLAN information across a trunked link. | ||

| A switch been configured for 3 VLANs: VLAN2, VLAN3, and VLAN4. A router has been added to provide communication between the VLANs. What type of interface is necessary on the router if only one connection is to be made between the router and the switch? | C. Although you can use either 100Mbps or 1Gbps Ethernet, the 100Mbps is necessary at a minimum and is the best answer to this question. You need to trunk the link from the switch to the router to make this connection work with inter-VLAN communication. | ||
| You want to improve network performance by increasing the bandwidth available to hosts and limit the size of the broadcast domains. Which of the following options will achieve this goal? | D. By creating and implementing VLANs in your switched network, you can break up broadcast domains at layer 2. For hosts on different VLANs to communicate, you must have a router or layer 3 switch. | ||
| Which of the following protocols are used to configure trunking on a switch? (Choose two.) | C, D. Cisco has a proprietary trunking protocol called ISL. The IEEE version is 802.1Q. | ||
| When a new trunk link is configured on an IOS-based switch, which VLANs are allowed over the link? | A. By default, all VLANs are allowed on the trunk link and you must remove by hand each VLAN that you don’t want traversing the trunked link. | ||
| Which switching technology reduces the size of a broadcast domain? | C. Virtual LANs break up broadcast domains in layer 2 switched internetworks | ||
| What VTP mode allows you to change VLAN information on the switch? | C. Only in server mode can you change VTP information on a switch. | ||
| Which command will configure a switch port to use the IEEE standard method of inserting VLAN membership information into Ethernet frames? | F. If you are on a 2950 switch, then the interface command is just switchport mode trunk, since the 2950 can only run the IEEE 802.1Q version. However, a 3550 can run both ISL and 802.1Q, so you must use the encapsulation command. | The argument to choose 802.1Q for a trunking protocol is dot1q. | |
| Which of the following is true regarding VTP? | A. All Cisco switches are VTP servers by default. No other VTP information is configured on a Cisco switch by default. You must set the VTP domain name | ||
| Which protocol reduces administrative overhead in a switched network by allowing the configuration of a new VLAN to be distributed to all the switches in a domain? | B. Virtual Trunk Protocol (VTP) is used to pass a VLAN database to any or all switches in the switched network. The three VTP modes are server, client, and transparent. | ||
| Which of the following commands sets a trunk port on a 2960 switch? | 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. | ||
| Which of the following is an IEEE standard for frame tagging? | C. 802.1Q was created to allow trunked links between disparate switches. | ||
| You connect a host to a switch port, but the new host cannot log into the server that is plugged into the same switch. What could the problem be? (Choose the most likely answer.) | D. This question is a little vague, but the best answer is that the VLAN membership for the port is not configured. | ||
| See graphic ch 9 problem 15 | See graphic ch 9 problem 15 | ||
| To configure the VLAN trunking protocol to communicate VLAN information between two switches, what two requirements must be met? (Choose two.) | C. Although one of the switches can be set to client, that would not stop them from sharing VLAN information through VTP. However, they will not share VLAN information through VTP if the domain names are not set the same. | ||
| Which of the following are benefits of VLANs? (Choose three.) | D. Switches do not propagate VLAN information by default; you must configure the VTP domain. VLAN Trunk Protocol (VTP) is used to propagate VLAN information across a trunked link. | ||
| Which of the following modes are valid when a switch port is used as a VLAN trunk? (Choose three.) | B, C, D. The valid modes of a VLAN trunk on a switch are dynamic auto, dynamic desirable, trunk (on), and nonegotiate.information between the switches. At least one of the switches must be a VTP server; the other switches should be set to VTP client. | ||
| These two switches are not sharing VLAN information. From the following output, what is the reason these switches are not sharing VTP messages? SwitchA#sh vtp status VTP Version : 2 Configuration Revision : 0 Maximum VLANs supported locally : 64 Num | SwitchA#sh vtp status VTP Version : 2 Configuration Revision : 0 Maximum VLANs supported locally : 64 Number of existing VLANs : 7 VTP Operating Mode : Server VTP Domain Name : RouterSim VTP Pruning Mode : Disabled | SwitchB#sh vtp status VTP Version : 2 Configuration Revision : 1 Maximum VLANs supported locally : 64 Number of existing VLANs : 7 VTP Operating Mode : Server VTP Domain Name : GlobalNet VTP Pruning Mode : Disabled | B, C, F. VLANs break up broadcast domains in a switched layer 2 network, which means smaller broadcast domains. They allow configuration by logical function instead of physical location and can create some security if configured correctly.B. Both switch |
| Which of the following provide inter-switch VLAN communication? (Choose two.) | B, C, D. The valid modes of a VLAN trunk on a switch are dynamic auto, dynamic desirable, trunk (on), and nonegotiate |
