去EMC笔试，本来还以为是智力测试啥的，一看到题目我就傻了，好专业，俨然一种要当炮灰的节奏，一怒之下就把所有的简答题都背了下来：
1. What is a file system? List all types of file system that you know.
2. What is the benefit of STP? List all types of STP that you know and describe them one by one.
3. How to change the root password on a Linux system?
4. What is the difference between soft link and hard link in a Unix system, and what is the pros and cons of them?
5. What is the basic difference between SAN and NAS?
6. Your customer wants to have a backup of his system, now you have two choices: Backup to Tape or Backup to Disk, the customer needs to recover the data ASAP when there's a system failure. Provide your suggestion and reasons.
7. If you are the network administrator in a company. One employee asks you for help because his Outlook can not send out email, and it's not the problem of Outlook itself, it a network issue, write down all your troubleshooting steps to solve this problem.
8. What is the benifit of Cloud Computing?
9. How many RAID implementation methods do you know? Please describe the differnces between them.
10. List at least 3 Relational DBMS and 1 NoSQL database.
我有自信大多数回忆还是准确的，有些表述可能会略有差别，主要的一些考察点应该都没有遗漏。
我不知道今年EMC的笔试是不是都结束了，今年如果用不上了希望对下几届的'同学有用吧，阿门!
整张卷子一共32道题， 10道单选，10道多选，10道简答还有两道论述小作文。
选择题实在背不下来，主要是我不是这个专业的，对这些术语一点感觉都没有，太不好背，不过大多数问题都是集中在什么Linux system，protocol，cloud computing等等，还有就是一些 command 什么的吧，我想对于相关专业要去EMC笔试的大牛们应该是小菜一碟，哈哈，再说选择题有选项要好很多哈，网上我看也有很多，大家可以一起参考下。
论述题第一道好像是客户遇到了一个什么问题，然后你没有权限解决，但客户一定要你解决，问你这种情况应该如何解决。另一题暂时想不起来了~~
