16. You are going to install a remote system using a WAN boot installation. Which two items are true of a WAN boot and must be part of your pre-installation checklist? (Choose two.)
A. WAN boot is supported on machines with SPARC and x86 CPUs.
B. You cannot use WAN boot on machines running the Solaris OS for x86 platforms.
C. A CDROM is required to access the wanboot program and WAN boot miniroot.
D. The system must have WAN boot support in the OBP or PXE support in the BIOS.
E. An HTTP server must be available on the network.

答案是BE, 我怎么觉得E不像啊？是D吧？各位认为呢？

50. One of your disks is almost full, so you decide to look for files that can be removed. Looking around the file
system, you find a directory with this content:
# ls -li
total 33570624
268566 -rw------- 5 bin bin 4294967296 Jan 23 11:59 file1
268566 -rw------- 5 bin bin 4294967296 Jan 23 11:59 file2
268566 -rw------- 5 bin bin 4294967296 Jan 23 11:59 file3
268566 -rw------- 5 bin bin 4294967296 Jan 23 11:59 file4
How much disk space can you reclaim by removing these files?
A. 0 bytes
B. 33,570,624 bytes
C. 4,294,967,296 bytes
D. 17,179,869,184 bytes
Answer: A

这题有点看不懂，第一个column是inode,说明这几个文件是同一个inode,5是link到这些文件的link数,这些文件都是硬链接文件？都是链接吗？所以不占空间?

50.  Since there are 5 link count and hard link doesn't take up disk space, by removing the 4 'filename'(ie. hard link), doesn't save you any space. You must remove the last filename (ie. the 5th one) to free up 4,294,967,296.  In this case, ls -li only give you 4 .

16.  I thought wan boot has to use http. Not 100% sure though.

感谢2位哦，wan boot好像是solaris的新玩意，可以远程，跨地区的通过http web server安装系统，不过觉得D也挺对的啊

easybegin

wan boot 好象是ILOM的功能，和OBP和PXE无关，所以选择BE是对的。

guopy007

E肯定是对的

yuhuohu

E肯定是对的 wan boot就是通过http协议来做的

B应该也是对的，B如果不对，那么AD都对了

明白了，多谢各位
