参考答案:B

第2题:

Router R1 connects to a Frame Relay cloud using a multipoint subinterface, with ten PVCs associated with the subinterface.What command would make this router not use a DR, and dynamically discover OSPF neighbors?()

A. ip ospf network broadcast

B. ip ospf network non - broadcast

C. ip ospf network point - to - multipoint

参考答案:C

第3题:

由R1、R2、R3组成的串联电路,已知电源电动势为12V,内阻 0.2Ω,R1= 4.8Ω,R3=7Ω,电阻R2为可变,当R2=__________时,R2获得最大功率。


正确答案:12Ω

第4题:

如图1-11所示,电阻R1=R2=R3=30 Ω,电源内阻忽略不计.已知当开关S断开时,电阻R3的功率P3=30 W.求:
(1)通过电阻R1的电流;

(3)当S合上时R3的电功率.


答案:
解析:


【解题指要】本题是有关电路计算的试题,考查的知识点是闭合电路欧姆定律、欧姆定律
和电功率等.解题的关键是弄清外电路中电阻的连接方式.特别要注意的是当开关S闭合后,电阻R1被短接,不起作用,外电路是R2、R3的并联电路.

第9题:

S0/0 on R1 is configured as a multipoint interface to communicate with R2 and R3 in the hub-and-spoke Frame Relay topology shown in the exhibit. Originally, static routes were configured between these routers to successfully route traffic between the attached networks. What will need to be done in order to use RIPv2 in place of the static routes?()

A.Configure the no ip subnet-zero command on R1, R2, and R3.

B.Dynamic routing protocols such as RIPv2 cannot be used across Frame Relay networks.

C.Configure the S0/0 interface on R1 as two subinterfaces and configure point-to-point links to R2 and R3.

D.Change the 172.16.2.0/25 and 172.16.2.128/25 subnetworks so that at least two bits are borrowed from the last octet.

E.Change the network address configuration to eliminate the discontiguous 172.16.2.0/25 and 172.16.2.128/25 subnetwork.


参考答案:C

第10题:

由证券主管当局、证券交易所、券商制定的最初保证金率R1、R2、R3的相互关系可表示为()。

A:R1≥R2≥R3
B:R1≤R2≤R3
C:R2≥R3≥R1
D:R3≥R1≥R2

答案:B
解析:
一般而言,最初保证金率由最高证券主管当局确定,证券交易所可以根据风险状况确定一个略高于证券主管当局的最初保证金率,券商又根据交易所确定的最初保证金率制定一个稍高的最初保证金率,即R1≤R2≤R3
