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. Relabel the file in question by using the restorecon command.

B. Allow httpd to read user content by using the setsebool command.

C. Allow httpd to read home directories by using the setsebool command.

D. Report a bug.

E. Generate a local policy by using the audit2allow command.

Examine the contents of the /etc/ocfs2/cluster.conf file: node: name = exam2 cluster = mycluster number = 0 ip_address = 192.168.56.106 ip_port = 7777

node: name = exam3 cluster = mycluster number = 1 ip_address = 192.168.56.107 ip_port = 7777 clustr: name = mycluster heartbeat_mode = local node_count = 2

3.

o2cb add-cluster mycluster

4.

o2cb add-node --ip 192.168.56.106 -- number 0 mycluster exam2

5.

o0cb config-cluster -node_count 2 mycluster

6.

o2cb configure

Examine the code fragment from /etc/tgt/targets.conf:

Which statement is true?

A. The syntax is invalid and causes the parser to fail when the target service is started. No LUN assignments are made and no disks are visible to the clients.

B. The syntax is invalid but defaults apply. If you assign any LUN addresses manually, then you must assign all for that target. Therefore, default assignments apply. physDisk1.img = 1, phyDisk2.img = 2. phyDisk3.img = 3

C. phyDisk1.omg is assigned the next available LUN number above the existing allocated numbers. LUN = 4

D. phyDisk1.img is assigned the lowes available LUN number that is not assigned. LUN = 2
