    D

    Economic security won’t be taken for granted by future young workers.


    正确答案： C
    解析：
    文章倒数第二段第一句指出职工的唯一的投资选择（sole investment option ）是造成悲剧的最大原因，从该段第二句也可看出，如果他们将投资分散在各个investment options的话，可能就不会造成这么大的悲剧，故A项正确。从文章可知，人们普遍认为I’ll-be-taken-care-of，但此次悲剧不仅说明了所谓的经济安全的瓦解，也警醒了他们须为自己负责，不能再想当然以为企业、社会或者政府会为他们负责。故B、D两项都正确。从最后一段可知，人们的思想观念不可能一下子转变过来，因而有可能这样的事会再发生，故C正确。D并不是从Enron disaster得到的教训。

    Identify three reasons that explain why assigning more than one managed serve achieve better  performance than running one managed server with more resources?（）
    A

    Thread management inside the JVM process might be less effective than context switching between processes on the OS level. It is better to combine both these technologies to achieve full saturation of resources.

    B

    Current CPUs are multicore units. So starting managed servers in the amount of physical cores and pinning them 1:1 to cores will always get the best performance.

    C

    By a combination of prioritization of processes on the OS level and Work Manager in WLS, one  could tune the whole environment more precisely.

    D

    Assigning more than one managed server to hardware will never bring better performance.

    E

    More instances means more connections to databases, so one could serve more concurrent  calls on the database level. This is primarily why this approach will give better performance numbers.

    F

    Depending on the profile of the application, having more JVMs with smaller heaps will lead to more predictable response times than fewer JVMs with a large heap.
