    有點久沒碰網路的東西了,儘量幫你找到答案囉~ 如果有誤請見諒。

    1:Which network design layer provides a connection point for end user devices to the network?

    (a)access

    (b)core

    (c)distribution

    (d)network

    => 提供用戶端連線至網路的layer, (a) Access Layer

    2:What are two examples of peripheral input devices? (Choose two.)

    (a) external modem

    (b)barcode reader

    (c)digital camera

    (d)plotter - output

    (e)printer - output

    => 周邊輸入設備, (b), (c)

    註: A peripheral is a device attached to a host computer behind the chipset whose primary functionality is dependent upon the host, and can therefore be considered as expanding the hosts capabilities, while not forming part of the system's core architecture.

    Some of the more common peripheral devices are printers, scanners, disk drives, tape drives, microphones, speakers, and cameras. Peripheral devices can also include other computers on a network system.

    3: What is the purpose of the ipconfig /release command?

    (a) It forces a client to give up its current IP address.

    (b)It forces a client to give up its current MAC address.

    (c)It forces the client to clear all the MAC address to IP address associati ons it has learned.

    (d)It shows the current IP configuration on the client.

    => (a), 釋放出現有IP

    4: Which protocol is used by a client to retrieve an e-mail from a remote server using a TCP/IP connection?

    (a)DNS

    (b)FTP

    (c)POP

    (d)HTTP
