第1题：

You need to configure two Ezonexam switches to exchange VLAN information. Which protocol provides a method of sharing VLAN configuration information between these two switches?

A. STP

B. 802.1Q

C. VLSM

D. ISL

E. VTP

F. HSRP

G. None of the above


正确答案：E
E 解析：Explanation:
VLAN Trunking Protocol (VTP) is a Cisco proprietary Layer 2 messaging protocol that manages the addition, deletion, and renaming of VLANs on a network-wide basis. Virtual Local Area Network (VLAN) Trunk Protocol (VTP) reduces administration in a switched network.

When you configure a new VLAN on one VTP server, the VLAN is distributed through all switches in the domain. This reduces the need to configure the same VLAN everywhere. To do this VTP carries VLAN information to all the switches in a VTP domain. VTP advertisements can be sent over ISL, 802.1q, IEEE 802.10 and LANE trunks.

VTP traffic is sent over the management VLAN (VLAN1), so all VLAN trunks must be configured to pass VLAN1. VTP is available on most of the Cisco Catalyst Family products.

第2题：

Which statement describe two of the benefits of VLAN Trunking Protocol?()

A. VTP allows routing between VLANs.

B. VTP allows a single switch port to carry information to more than one VLAN.

C. VTP allows physically redundant links while preventing switching loops.

D. VTP simplifies switch administration by allowing switches to automatically share VLAN configuration information.

E. VTP helps to limit configuration errors by keeping VLAN naming consistent across the VTP domain.

F. VTP enhances security by preventing unauthorized hosts from connecting to the VTP domain.


参考答案：D, E

第3题：

You are an administrator of the Ezonexam switched network and your goal is to reduce some of the administrative overhead on your network. You plan on achieving this by configuring a new VLAN for each department in the Ezonexam network.

However, you need to share the VLAN information across numerous switches. Which of the following would allow you accomplish this?

A. STP

B. GVRP

C. SNMP

D. VTP

E. DHCP

F. None of the above


正确答案：D
D 解析：Explanation:
The VTP (VLAN Trunking Protocol) is a Cisco Layer 2 messaging protocol that manages the addition, deletion, and renaming of VLANs on a network-wide basis. It allows for VLAN information to span multiple switches within the switch domain.

Incorrect Answers:
A. STP is a switching protocol but it is used for preventing network loops.

B. GVARP is an actual protocol used in switch administration, but it beyond the scope of what a CCNA is expected to know.

C. SNMP is a protocol used for managing and monitoring networks

E. DHCP is the Dynamic Host Configuration Protocol, which allows for PC's to obtain their IP address dynamically upon booting up, along with their DNS and default gateway information.

第4题：

Which of the following are benefits of segmenting a network with a router?()

A. Broadcasts are not forwarded across the router.

B. All broadcasts are completely eliminated.

C. Adding a router to the network decreases latency.

D. Filtering can occur based on Layer 3 information.

E. Routers are more efficient than switches and will process the data more quickly.

F. None of the above.


参考答案：A, D

第5题：

Which one of the following is the most commonly used layer 2 network device?()

A. Hub

B. Bridge

C. Switch

D. Router

E. Repeaters

F. None of the above


参考答案：C

第6题：

Which protocol automates all of the following functions for hosts on a network: IP configuration, IP addresses, subnet masks, default gateways, and DNS server information?

A. CDP

B. SNMP

C. DHCP

D. ARP

E. DNS

F. None of the above


正确答案：C
C 解析：Explanation:
DHCP uses the concept of the client making a request and the server supplying the IP address to the client, plus other information such as the default gateway, subnet mask, DNS IP address, and other information.

Incorrect Answers:
A. CDP is the Cisco Discovery Protocol. It is used by Cisco devices at the data link layer to obtain information about their directly connected neighbors.

B. SNMP is the Simple Network Management Protocol. This is used for the maintenance, management, and monitoring of network devices.

D. ARP is the Address Resolution Protocol, which is used to resolve layer 2 MAC addresses to layer 3 IP addresses.

E. DNS is the Domain Name Service. It is used to resolve domain names (for example, www.ezonexam.com) to IP addresses. The IP address location of primary and secondary DNS resolver servers can be obtained for hosts using DHCP.

参考答案：D

第8题：

Which of the following steps are necessary in order to add a new VLAN to the Ezonexam switched network? (Select all that apply)

A．Create the VLAN.

B．Name the VLAN.

C．Configure an IP address for the VLAN.

D．Add the desired ports to the new VLAN.

E．Add the VLAN to the VTP domain.


正确答案：ABD
解析：Explanation:
The following are the basic requirements for creating VLANs:
* Creating the VLAN numbers and names
* Configuring each port's assigned VLAN

Incorrect Answers:
C. This is an optional feature, but not a necessary step for creating a VLAN.

E. Adding any VLAN to a Virtual Trunking Protocol (VTP) domain may be desired in a complex multi-switch and multi-VLAN network. However, it is not a necessary step for creating stand-alone VLANs on a single switch.
