1. Which one of the following is NOT an advantage of using SAM rather than "ps" and "kill" in order to kill all the processes initiated by one login session?
A. SAM allows you to select multiple processes.
B. SAM allows you to try a "safe kill."
C. SAM requires fewer system resources.
D. SAM allows you to select processes by user or parent.
E. SAM shows them grouped by parent process.
Should I choose A. or C.?
I noticed that I could use SAM to select multiple processes under "Processs Management -> Process Control", but when I choosed "Action", I can see "==" under the menu, is that a bug or it can't really use for multiple processes.
Because I doubt "C. SAM requires fewer system resources."
2. super block last mounted on: /
magic 95014 clean FS_OK time Sun Jul 2 16:41:14
2000
sblkno 16 cblkno 24 iblkno 32 dblkno 80
sbsize 2048 cgsize 2048 cgoffset 24 cgmask 0xfffffff8
ncg 39 size 94208 blocks 91669
bsize 8192 bshift 13 bmask 0xffffe000
In the above fragment of output from the tunefs -v command, which one of the following field/number specifies that the filesystem will take filenames longer than 14 characters?
A. bsize 8192
B. sbsize 2048
C. bmask 0xffffe000
D. cgmask 0xfffffff8
E. magic 95014
I tried to search for the docs about superblock, but I couldn't find anything about what to control "14 characters filenames".
3. Which one of the following is the sequence of actions that must be taken to build a new kernel?
A. cd /stand; modify system; config system; make -f config.mk
B. cd /system; modify system; config system
C. cd /stand; modify system; config config.mk
D. cd /stand; modify system; make -f config.mk; config system
E. cd /stand; modify system; make -f system
What's that "make" for? I couldn't find any doc for building the kernel with "config" and "make", are the commands too old for rebuilding the kernel?
Please help me out! Thanks once again!
Solved! Go to Solution.

Re: 3 questions about SAM,superblock and config
A. SAM allows you to select multiple processes. --this is not true.
B. SAM allows you to try a "safe kill." --this is true. but this is an advantage only.
D and E.--i think they are not the answer.
i will select the "D"
3.)i will select "D. cd /stand; modify system; make -f config.mk; config system"

Re: 3 questions about SAM,superblock and config
About Queston 1, you said "A" is not true, but why did you choose "D"?
And do you think "SAM requires fewer system resources" than just useing "kill" command?
Thanks!

Re: 3 questions about SAM,superblock and config
A, D, E omitted and in B and C, sam not uses fewer system resources, i think. kill is the straight forward way.
so i will select "C".

Re: 3 questions about SAM,superblock and config
My vote is "C". (but compared to what?)
Hope this helps!

Torsten.

Re: 3 questions about SAM,superblock and config
Someone asked me these questions and I am so curious to know the answers for them, especially question #2.
BTW, do you have any doc for me to learn the detail about superblock? Thanks a lot!
