第3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.

第9题：

In which of the following scenarios would the "show cdp neighbors detail"command be an appropriate troubleshooting tool?（）

  • A、Two switches are connected via a trunk. Both switches have been assigned an IP address, subnet mask, and default gateway. A ping is successful between the two switches. However, VLAN information is not passed from one switch to the other switch.
  • B、A router and a switch have been assigned an IP address, a subnet mask, and a default gateway. They are directly connected, but a ping between the two devices fails.
  • C、A router connects to another router through a serial interface. Both routers have been assigned an IP address, subnet mask, and default gateway. The routers are running RIP and the networks directly connected to the first router do not pass to the second router. However, a ping from one router to the serial interface of the directly connected neighboring router is successful.
  • D、A router connects to another router via a switch. Both routers and the switch have been assigned an IP address, subnet mask, and default gateway. Neither the routers nor the switch are able to ping one of the hosts that is directly to the switch.
