第1题：

A new switch is being installed in the Ezonexam network and you have been assigned the task of connecting it to an existing switch. In doing this, you want to set up the VLAN Trunking Protocol so that VLAN information can be passed between the switches. Which of the following must you do to accomplish this? (Choose all that apply).

A．You must set each end of the trunk line to IEEE 802.1e encapsulation.

B．You must set the same VTP management domain name on both switches.

C．You must set all ports on the two switches as access ports.

D．You must configure one of the switches as a VTP server.

E．You must use a rollover cable to connect the two switches.

第6题：

What are some of the characteristics of a typical VLAN arrangement, found throughout the Ezonexam switched LAN? (Select all that apply)

A. VLANs logically divide a switch into multiple, independent switches at Layer 2.

B. Trunk links can carry traffic for multiple VLANs.

C. VLAN implementation significantly increases traffic due to added trunking information.

D. A VLAN can span multiple switches.

E. VLANs typically increase the number of switches needed

F. VLANs typically decrease the number of switches needed


正确答案：ABD
A,B,D 解析：Explanation:
VLANs give you the power of making virtual LAN networks to subdivide collision domains into smaller units of functionality, without being limited by physical location.

A is correct because that is the exact function of a VLAN. B is correct because trunk links are used to carry traffic for multiple VLANs. D is correct because a VLAN can and often does span across multiple switches. VTP makes this possible.

Incorrect Answers:
C. Although trunking information does indeed add some level of overhead, the overall traffic overhead is greatly reduced though the use of VLANs.

E, F. The number of total switches needed in a network is the result of the number of devices on the entire LAN that need to be connected. Whether VLANs are used or not will have little, if any, impact on the total number of switches needed in a LAN.

第7题：

Whoever is in charge of ___ the event must have the ability to work on multiple tasks atthe same time.

A. coordinating
B. intending
C. collaborating
D. depending

第8题：

What must the Ezonexam network administrator do in order to successfully configure a VLAN trunk between two switches named VE1 and VE2? (Select two answer choices)

A. Set each end of the trunk line to IEEE 802.1Q encapsulation.

B. Set the same VTP management domain name on both switches.

C. Set all ports on the two switched as access ports.

D. Configure one of the two switches as a VTP server.

E. Connect the two switches using a rollover cable.

F. Use a router to forward VTP traffic between the VLANs.


正确答案：BD
B,D 解析：Explanation:
All servers that need to share VLAN information must use the same domain name, and a switch can only be in one domain at a time. This means that a switch can only share VTP domain information with other switches if they're configured into the same VTP domain. You can use a VTP domain if you have more than one switch connected in a network, but if you've got all your switches in only one VLAN, you don't need to use VTP. VTP information is sent between switches via a trunk port.

Switches advertise VTP management domain information, as well as a configuration revision number and all known VLANs with any specific parameters. There's also something called VTP transparent mode, in it, you can configure switches to forward VTP information through trunk ports, but not to accept information updates or update their VTP databases. At least one of the switches will need to be configured as the VTP server in order to pass the VLAN info.

Incorrect Answers:
A. Although this is a valid option, it is not a requirement since using ISL as the encapsulation type is also a valid option.

E. A rollover cable is not used between switches for any of the port types.

F. Routers will be required for sending traffic from one VLAN to the other, but not to forward the actual VTP traffic.
