第1题：

Intermediate system to intermediate system (IS - IS), is a protocol used by network devices (routers) to determine the best way to forward datagrams through a packet - switched network, a process called routing. Which three attributes are of the IS - IS routing protocol? （）

A. supports VLSM

B. link - state routing protocol

C. operati on is similar to BGP

D. supports two routing levels within an autonomous system


参考答案：A, B, D

第2题：

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?()

A. STP

B. VTP

C. GVRP

D. SNMP

E. DHCP


参考答案：B

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.

D.administrative distance

E.link delay


参考答案：D

第8题：

Which of the following components must be elected before the Spanning Tree Protocol can converge in a switched LAN?

A. Designated ports.

B. Duplex operating mode.

C. Fast mode ports.

D. Root bridge.

E. Root ports.

F. BDPU priority.


正确答案：ADE
A,D,E 解析：Explanation:
Designated port: Either a root port or a port that has been determined as having the best (lower) cost-a designated port will be marked as a forwarding port.

Root bridge: The root bridge is the bridge with the best bridge ID. With STP, the key is for all the switches in the network to elect a root bridge that becomes the focal point in the network. All other decisions in the network-like which port is to be blocked and which port is to be put in forwarding mode-are made from the perspective of this root bridge.

Root port: Always the link directly connected to the root bridge, or the shortest path to the root bridge. If more than one link connects to the root bridge, then a port cost is determined by checking the bandwidth of each link. The lowest cost port becomes the root port.

So these three components must be elected before the spanning tree protocol can converge in a switched LAN
