前几天花10两银子买的，有几道题思来想去，不是很清楚，特此请教。
就是页眉标有
pass4sureexams@gmail.com的那套。
42. The /home filesystem is 100% full and errors are generated trying to increase the size
usingchfs. Which of the following is most likely causing the problem?
A./tmp is 100% full
B./var is 100% full
C./home is still mounted
D.A user is editing a file residing in /home
Answer:
A
推测是用了排除法吧？除了a之外，其余的可能性不大，选a。对不对？
46. A System p administrator needs to replace a failed internal disk in a mirrored rootvg.
Which ofthe following is one of the steps that would need to be followed?
A.Deallocate rootvg mirror
B.Use hot replace manager
C.Deallocate LPs from failed disk
D.Deallocate PPs from failed disk
Answer:
D
mirrored vg需要先解除mirror，难道rootvg不是这样吗？答案d是针对非mirror情况的，我觉得应该是A，我的理解没有问
题吧。
48. A System p administrator has a development p520. The customer backs up all critical data
daily to a SAN.
Which of the following would be included in a reasonable disaster recovery plan for this p520?
A.Sunday's full backup tape only
B.Tuesday's differential backup tape only
C.Sunday's full backup tape and Tuesday's differential tape
D.Sunday's full backup tape and Monday's through Tuesday's differential backup tapes
Answer:
C
这样理解对不对：all critical data daily不是全备，因此建议一个灾备方案是周日全备，周二再做一
个差异备份。
49. A system p administrator is using the backup command to archive the datavg volume
group.Which command should also be used to record the LV structure and sizes so the
filesystems in the datavg volume group appear the same after a restore?
A.Annual savevg of data VG
B.Three node HACMP cluster
C.Daily savevg of the data VG
D.Recent bootable mksysb
Answer:
D
savevg难道不可以记录datavg中的lv结构和大小？还是restvg不能按照原结构进行恢复？c对不对？
65. Which of the following commands would the system administrator use to add an entry to
the root crontab file and refresh cron?
A.crontab -a
B.crontab -r
C.crontab -e
D.crontab -l
Answer:
D
crontab -e是用户编辑和更新用的，crontab -l是列出crontab文件用的。如果理解题目中root只是add一
个entry，可以用-l，但是还是应该用-e刷新一下啊？选择d应该说不完整吧。
先谢过。
