A.tracert corp7.microsoft.com

B.rout corp7.microsoft.com

C.ping corp7.microsoft.com

D.netstat corp7.microsoft.com

答案

参考答案:A

解析:

本题考查网络管理工具的使用技巧。

tracert命令的功能是确定到达目标的路径,并显示通路上每一个中间路由器的IP地址。通过多次向目标发送ICMP回声(echo)请求报文,每次增加IP头中TTL字段的值,就可以确定到达各个路由器的时间。显示的地址是路由器接近源的这一边的端口地址。

tracert命令的语法如下:

对常用参数解释如下:

●-d不进行名字解析,显示中间节点的IP地址,这样可以加快跟踪的速度。

●-hMaximumHops说明地址搜索的最大跃点数,默认值是30跳。

●-jHostList说明发送回声请求报文要使用IP头中的松散源路由选项,标识符HostList列出必须经过的中间节点的地址或名字,最多可以列出9个中间节点,各个中间节点用空格隔开。

●-wTimeout说明了等待ICMP回声响应报文的时间(μs),如果接收超时,则显示星号"*",默认超时间隔是4s。

●TargetName用IP地址或主机名表示的目标。

    According to a recent survey on money and relationships, 36% of people are keeping

a bank account from their partner. While this financial unfaithfulness may appear as

distrust in a relationship, in truth it may just be a form of financial protection. With

almost half of all marriages ending in divorce, men and women are realizing they need to

be financially savvy, regardless of whether they are in a relationship.

    The financial hardship on individuals after a divorce can be extremely difficult,

even more so when children are involved. The lack of permanency in relationships, job and

family life may be the cause of a growing trend to keep a secret bank account hidden from

a partner, in other words, an "escape fund".

    Margaret's story is far from unique. She is a representative of a growing number of

women in long-term relationships who are becoming protective of their own earnings. Every

month on pay day, she banks hundreds of dollars into a savings account she keeps from her

husband. She has been doing this throughout their six-year marriage and has built a nest

egg worth an incredible $100,000. Margaret says if her husband found about her secret

savings he'd be hurt and would take this as a sign that she wasn't sure of the marriage.

"He'd think it was my escape fund so that financially I could afford to get out of the

relationship if it went wrong. I know you should approach marriage as being forever and

I hope ours is, but you can never be sure." Like many of her fellow secret savers,

Margaret was hurt in a former relationship and has since been very guarded about her own

money.

    Coming clean to your partner about being a secret saver may not be all that bad. Taken

Colleen for example, who had been saving secretly for a few years before she confessed to

her partner. "I decided to open a savings account and start building a nest egg of my own.

I wanted to prove to myself that I could put money in the bank and leave it there for a

rainy day."
