  • 第13题：

    The network administrator has configured port security on a Ezonexam switch. Why would a network administrator configure port security on this Ezonexam device?

    A．To prevent unauthorized hosts from getting access to the LAN

    B．To limit the number of Layer 2 broadcasts on a particular switch port

    C．To prevent unauthorized Telnet or SSH access to a switch port

    D．To prevent the IP and MAC address of the switch and associated ports

    E．None of the above


    正确答案：A
    解析：Explanation:
    You can use the port security feature to restrict input to an interface by limiting and identifying MAC addresses of the stations allowed to access the port. When you assign secure MAC addresses to a secure port, the port does not forward packets with source addresses outside the group of defined addresses. If you limit the number of secure MAC addresses to one and assign a single secure MAC address, the workstation attached to that port is assured the full bandwidth of the port.

    If a port is configured as a secure port and the maximum number of secure MAC addresses is reached, when the MAC address of a station attempting to access the port is different from any of the identified secure MAC addresses, a security violation occurs. Also, if a station with a secure MAC address configured or learned on one secure port attempts to access another secure port, a violation is flagged.

    You are the administrator of a Windows 2000 network. The network includes a Windows 2000 Server computer that is used as a file server. More than 800 of Ezonexam.com's client computers are connected to this server.

    A shared folder named Data on the server is on an NTFS partition. The data folder contains more than 200 files. The permissions for the data folder are shown in the following table.

    Type of permission Account Permission

    Share Users Change

    NTFS Users Full Control

    You discover that users are connected to the Data folder. You have an immediate need to prevent 10 of the files in the Data folder from being modified. You want your actions to have the smallest possible effects on the users who are using other files on the server.

    What two actions should you take? (Choose Two)

    A．Modify the NTFS permissions for the 10 files.

    B．Modify the NTFS permissions for the Data folder.

    C．Modify the shared permissions for the Data folder.

    D．Log off the users from the network.

    E．Disconnect the users from the Data folder.


    正确答案：AE
    解析：Explanation: In this scenario our guideline would be to cause the network users as little disruption as possible. We would do this by only modifying the NTFS permissions on the 10 specific files. Then all users must be disconnected from the Data folder.

    Incorrect answers:
    B: Permissions only need to be changed on the files, not on the whole folder.

    C: Permissions only need to be changed on the files, not on the whole folder.

    D: It is not necessary to log off the users from the network. They only have to be disconnected from the folder.
