  • 第5题:

    You have configured a Ezonexam switch as shown below:

    Ezonexam3(config-if) switchport port-security

    Ezonexam3(config-if) switchport port-security mac-address sticky

    Select the action below that results from executing these commands.

    A. A dynamically learned MAC address is saved in the VLAN database.

    B. A dynamically learned MAC address is saved in the startup-configuration file.

    C. Statically configured MAC addresses are saved in the startup-configuration file if frames from that address are received.

    D. A dynamically learned MAC address is saved in the running-configuration file.

    E. Statically configured MAC addresses are saved in the running-configuration file if frames from that address are received.

    F. None of the above


    正确答案:D
    D 解析:Explanation:
    With port security, the switch supports these types of secure MAC addresses:

    Static secure MAC addresses-These are manually configured by using the switchport port-security mac-address mac-address interface configuration command, stored in the address table, and added to the switch running configuration.

    Dynamic secure MAC addresses-These are dynamically configured, stored only in the address table, and removed when the switch restarts.

    Sticky secure MAC addresses-These are dynamically configured, stored in the address table, and added to the running configuration. If these addresses are saved in the configuration file, when the switch restarts, the interface does not need to dynamically reconfigure them.

    You can configure an interface to convert the dynamic MAC addresses to sticky secure MAC addresses and to add them to the running configuration by enabling sticky learning. To enable sticky learning, enter the switchport port-security mac-address sticky interface configuration command. When you enter this command, the interface converts all the dynamic secure MAC addresses, including those that were dynamically learned before sticky learning was enabled, to sticky secure MAC addresses. The interface adds all the sticky secure MAC addresses to the running configuration.

    The sticky secure MAC addresses do not automatically become part of the configuration file, which is the startup configuration used each time the switch restarts. If you save the sticky secure MAC addresses in the configuration file, when the switch restarts, the interface does not need to relearn these addresses. If you do not save the sticky secure addresses, they are lost.
