[学习交流] CCNA640-802 V13题库试题分析20(艾迪飞吴老师讲解)

1A  routing protocol is required that supports:

1) routing update authentication

2) an addressing scheme that conserves IP addresses

3) multiple vendors

4) a network with over 50 routers

Which routing protocol fulfills these requirements?

A. RIPv1

B. RIPv2

C. EIGRP

D. OSPF

Answer: D

解释一下:首先RIPv1是不支持认证的,因此答案A我们可以排除。

是支持多厂商的,因此是一个开放的标准的协议,可以排除EIGPR,因为这是个CISCO私有的协议。

网络的大小可以超过50台路由器,那RIPv2就不满足了,因为RIP最大支持16跳。

那么答案就是OSPF了。

 

 

2When a new trunk is configured on a 2950 switch, which VLANs by default are allowed over the trunk link?

A. no VLANs

B. all VLANs

C. only VLANs 1 - 64

D. only the VLANs that are specified when creating the trunk

Answer: B

解释一下:Trunk上默认是可以转发所有VLAN的数据的。
