第1题：

Which two multicast protocol statements are true?()

A. Sparse mode multicast uses a pull model to send multicast traffic to where it is requested

B. Dense mode multicast uses a push model to flood traffic throughout the network and then prunes the unwanted traffic

C. Dense mode multicast requires explicit join messa ges from their members

D. Sparse mode uses reverse path forwarding (RPF) to prune off redundant flows

E. The primary use of sparse mode multicast is for test labs and router performance testing


参考答案：A, B

第2题：

Which three statements are true about the Internet Group Management Protocol (IGMP)? ()

A. There are three IGMP modes: dense mode, sparse mode, and sparse - dense mode

B. IGMP is used to register individual hosts with a multicast group

C. IGMP version 3 enables a multicast receiving host to specify to the router which sources it should forward traffic from

D. IGMP messages a re IP datagrams with a protocol value of 2, destination address of 224.0.0.2, and a TTL value of 1

E. IGMP is a multicast routing protocol that makes packet - forwarding decisions independent of other routing protocols such as EIGRP

F. IGMP snooping ru ns on Layer 3 routers


参考答案：B, C, D

第3题：

For each blank, choose the best answer from the four choices and write down on the answer'sheet.

(66)is a protocol that a host uses to inform. a router when it joins or leaves an Internet multicast group.

(67)is an error detection code that most data communication networks use.

(68)is an interior gateway protocol that uses a distance vector algorithm to propagate routing information.

(69)is a transfer mode in which all types of information are organized into fixed form. cells on an asynchronous or non-periodic basis over a range of media.

(70)is an identifier of a web page.

A．ICMP

B．SMTP

C．IGMP

D．ARP


正确答案：C
解析：IGMP协议是接收者发现协议。IGMP协议运行在主机和路由器之间，用于路由器维护组播组是否有组成员。IGMP只维护组播组是否有成员，而不维护组播组有哪些成员，因此状态信息不会因组播组成员的增加而增加。
  循环冗余校验(cyclic redundancy check，CRC)是由分组线性码的分解而来，其主要应用是二元码组，主要应用于数据传输过程中的差错控制。
  OSPF是一个内部网关协议(Interior Gateway Protocol，IGP)，用于在单一自治系统 (autonomous system，AS)内决策路由。与RIP相对，OSPF是链路状态路由协议，而RIP是距离向量路由协议。它是依靠距离，即跳数来衡量一条路径的好坏。通过距离向量路由算法来传播路由信息。
  ATM是异步传输模式，实现OSI物理层和链路层功能。ATM以独有的ATM信元进行数据传输，每个ATM信元为53个字节。ATM不严格要求信元交替地从不同的源到来，每一列从各个源来的信元，没有特别的模式，信元可以从任意不同的源到来，而且不要求从一台计算机来的信元流是连续的，数据信元可以有间隔，这些间隔由特殊的空闲信元(idle cell)填充。
  URL(Uniform. Resource Locator)是单一资源定位符，是一种用来鉴别文件与资源在WWW中地址的专用表示。

第6题：

Which two statements are true about Internet Group Management Protocol (IGMP) snooping?()

A. IGMP snooping and Cisco Group Membership Protocol (CGMP) can be used simultaneously on a switch.

B. IGMP snooping a nd Cisco Group Membership Protocol (CGMP) were developed to help Layer 3 switches make intelligent forwarding decisions on their own.

C. IGMP snooping examines IGMP join/leave messages so that multicast traffic is forwarded only to hosts that sent an IG MP message toward the router.

D. IGMP snooping is an IP multicast constraining mechanism for Layer 2 switches.

E. IGMP snooping is enabled with the ip multicast - routing global configuration command.


参考答案：C, D
