- Question
A switch has been configured for three different 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?
Options- A. 10Mbps Ethernet
- B. 56Kbps Serial
- C. 100Mbps Ethernet
- D. 1Gbps Ethernet
- Correct Answer
- 100Mbps Ethernet
ExplanationAlthough 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. - 1. Which of the following is an IEEE standard for frame tagging?
Options- A. ISL
- B. 802.3Z
- C. 802.1Q
- D. 802.3U Discuss
- 2. Which of the following commands sets a trunk port on a 2960 switch?
Options- A. trunk on
- B. trunk all
- C. switchport trunk on
- D. switchport mode trunk Discuss
- 3. To configure the VLAN trunking protocol to communicate VLAN information between two switches, what two requirements must be met?
- Each end of the trunk link must be set to the IEEE 802.1e encapsulation.
- The VTP management domain name of both switches must be set the same.
- All ports on both the switches must be set as access ports.
- One of the two switches must be configured as a VTP server.
- A rollover cable is required to connect the two switches together.
- A router must be used to forward VTP traffic between VLANs.
Options- A. 1, 2 and 4
- B. 3, 5 and 6
- C. 2 and 4
- D. 1 and 6 Discuss
- 4. Which of the following are benefits of VLANs?

- They allow logical grouping of users by function.
- They can enhance network security.
- They increase the size of broadcast domains while decreasing the number of collision domains.
- They simplify switch administration.
- They increase the number of broadcast domains while decreasing the size of the broadcast domains.
Options- A. 1 and 5
- B. 2 and 4
- C. 1, 3 and 5
- D. 2, 3 and 6 Discuss
- 5. Which of the following is true regarding VTP?
Options- A. All switches are VTP servers by default.
- B. All switches are VTP transparent by default.
- C. VTP is on by default with a domain name of Cisco on all Cisco switches.
- D. All switches are VTP clients by default. Discuss
- 6. 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?
Options- A. Managed hubs
- B. Bridges
- C. Switches
- D. Switches configured with VLANs Discuss
- 7. What VTP mode allows you to change VLAN information on the switch?
Options- A. Client
- B. STP
- C. Server
- D. Transparent Discuss
- 8. When a new trunk link is configured on an IOS-based switch, which VLANs are allowed over the link?
Options- A. By default, all VLANs are allowed on the trunk.
- B. No VLAN's are allowed, you must configure each VLAN by hand.
- C. Only configured VLAN's are allowed on the link.
- D. Only extended VLAN's are allowed by default. Discuss

- Blocking
- Dynamic auto
- Dynamic desirable
- Nonegotiate
- Access
- Learning

Correct Answer: 802.1Q
Explanation:
802.1Q was created to allow trunked links between disparate switches.
Correct Answer: switchport mode trunk
Explanation:
To set a switch port to trunk mode, which allows all VLAN information to pass down the link, use the
switchport mode trunk command.
Correct Answer: 2 and 4
Explanation:
You must have the same VTP domain name on all switches in order to share VLAN information between the switches. At least one of the switches must be a VTP server; the other switches should be set to VTP client.
Correct Answer: 2, 3 and 6
Explanation:
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.
Correct Answer: All switches are VTP servers by default.
Explanation:
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 on all switches to be the same domain name or they will not share the VTP database.
Correct Answer: Switches configured with VLANs
Explanation:
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.
Correct Answer: Server
Explanation:
Only in server mode can you change VTP information on a switch.
Correct Answer: By default, all VLANs are allowed on the trunk.
Explanation:
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.
Correct Answer: 2, 3 and 4
Explanation:
The valid modes of a VLAN trunk on a switch are dynamic auto, dynamic desirable, trunk (on), and nonegotiate.
Correct Answer: VTP
Explanation:
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.
