문제1
A system has several multipathed devices. Some of them are in use with mounted file systems.
The remaining multipathed devices are unused.
The multipath command with the -F option is issued as shown:
[root@host03 /]# multipath -F
Which statement is true?

A. All multipath mapping are flushed, thus removing theirmpathmappings. The mounted file system is unusable.

B. All multipath mapping except those that are in use are flushed, removing their mappings. The mounted file system is unaffected.

C. The command returns a syntax error because an mpath device name must be supplied as the argument to the-Fswitch.

D. Any faulted multipath devices are fixed, causing their faulty paths to be rediscovered if the underlying device is found to be available again. The mounted file system is unaffected.

정답: A

문제2
Examine the sequence:
# sealert -l dda34207-61fd-4de2-831d-039c79270864
SELinux is preventing /usr/sbin/httpd from read access on the
file /var/www/manual/new_features_2_2.html.
***** Plugin restorecon (85.9 confidence) suggests *****
If you want to fix the label.
/var/www/manual/new_features_2_2.html default label should be httpd_sys_content_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /var/www/manual/new_features_2_2.html
***** Plugin catchall_boolen (7.33 confidence) suggests *****
If you want to allow httpd to read user content
Then you must tell SELinux about this by enabling the 'httpd_read_user_content' boolean. You
can read 'user_selinux' man page for more details.
Do
setsebool -P httpd_read_user_content 1
What action must you take for fix this problem?

A. Report a bug.

B. Allowhttpdto read home directories by using thesetseboolcommand.

C. Allowhttpdto read user content by using thesetseboolcommand.

D. Relabel the file in question by using therestoreconcommand.
