    A. that you have observed
    B. that how you have observed
    C. how that you have observed
    D. how what you have observed

    答案:D
    解析:
    考查从句。show sb sth结构,这里sth是how引导的宾语从句,宾语从句中缺主语,what引导的主语从句,翻译为“所??的”what作observe的宾语。句意为“他的发言将向你展示,你所观察到的如何被用于其他语境”。所以正确答案为D。

    What is the net effect of the following command?()   alter diskgroup dgroup1 drop disk abc;
    A

     The disk ABC will be dropped from the disk group. Since you did not issue a rebalance command,the data on that disk will be lost.

    B

     The command will raise an error indicating that you need to rebalance the disk group to remove the data from that disk prior to dropping the disk.

    C

     The disk group will be automatically rebalanced during the drop operation. Once the rebalancing is complete,the disk will be dropped.

    D

     This command will fail because you cannot drop a specific disk in an ASM disk group.

    E

     The disk drop command will be suspended for a predetermined amount of time,waiting for you to also issue an alter diskgroup rebalance command. Once you have issued the rebalance command,ASM will proceed to rebalance the disk group and then drop the disk.
