NO.1 Examine the command on its output:

[root@FAROUT ~] # modprobe -v nfs

Insmod /lib/modules/ 2.6.39-100.0.12.e16uek.x86_64 /kernel/fs/nfs_common/nfs_acl.ko insmod

/lob/modules/ 2.6.39

100.0.12.e16uek.x86_64 /kernel/net/sunrpc/auth_gss/auth_rpcgss.ko

Insmod /lib/modules/ 2.6.39-100.0.12.e16uek.x86_64 /kernel/fs/fscache/fscache/ko

Insmod /lib/modules/ 2.6.39-100.0.12.e16uek.x86_64 /kernel/fs/locked.ko

Insmod /lib/modules/ 2.6.39-100.0.12.e16uek.x86_64 /kernel/fs/nfs/nfs.ko

Which two statements are true about the modprobe command?

A. It will load the nfs module if all the modules upon which it depends have been loaded.

B. It displays the dependency resolution for the nfs module and loads all the modules upon which

nfs depends before loading the nfs module.

C. It verifies that the nfs module and all other modules that depend on the nfs module are installed.

D. It displays the dependency resolution that would occur if the nfs module were to be loaded using

modprobe nfs.

E. It only loads the nfs module if all the modules upon which it depends have not been loaded yet.

NO.2 This MDADM output:

Which two aspects can be determined from this output?

A. A device failed and has been removed from this RAID set.

B. It is no longer possible to write to this RAID set.

C. Read and write performance is no longer optimal on this RAID set.

D. This RAID set was built without a spare device.

E. Only Write performance is no longer optimal on this RAID set.

Answer: A,D

 

NO.3 Which two statements are true concerning the installation and configuration of the

bootloader by the Anaconda installer, which is then used to boot Oracle Linux?

A. The Linux Loader (LILO) bootloader may be chosen for installation.

B. The bootloader must be password protected and Anaconda prompts for a password in all cases.

C. The Grand Unified Bootloader (GRUB) is the only bootloader used by Oracle Linux.

D. If previously installed operating systems are found on disk partitions that were not overwritten,

then an attempt is made to configure the bootloader to be able to boot them.

E. The bootloader is installed by default in the first partition of the disk.

Answer: A,E

Explanation:

A (not C): Linux boot process from hard drive:

1.PC initializion phase - BIOS, POST.

2.PC starts boot loader - usually grub or lilo.

3.The bootloader locates kernel image on the hard drive.

4.The kernel decompresses and loads itself. Once finished it tries to mount the root filesystem. 5.

When the root filesystem is mounted, /sbin/init is executed and continues booting the system using

inittab and /etc/rc*.d scripts

 

NO.4 Examine these statements and their output taken right after successful install of Oracle Linux:

[root@FAROUT /] rpm -q firstboot

Firstboot -1.110.10-1.0.2.e16.x86_64

[root @FAROUT /] # chkconfig - - list firstboot

Firstboot 0:off 2:off 3:off 4:off 5:off 6;off

[root@FAROUT /] # /etc/sysconfig/firstboot

RUN_FIRSTBOOT=NO

What is the conclusion?

A. The option to run firstboot was deselected during Oracle Linux installation.

B. The system was installed with desktop graphical packages and rebooted and the firstboot utility

ran successful.

C. Firstboot never ran in any run level because the service is turned off for all run levels.

D. The system was installed without selecting desktop graphical packages, thereby disabling

firstboot from running.

Answer: A

Explanation:

Firstboot is set to off for all levels.

Example:

The rm command below remove or delate the firstboot file in order to make sure the firstboot

program running when we restart or reboot the Fedora machine.

[root@fedora ~]# rm /etc/sysconfig/firstboot

rm: remove regular file `/etc/sysconfig/firstboot'? y

[root@fedora ~]#

Then check and make sure that firstboot program or firstboot service is run when your Fedora

startup/boot up.

Check firstboot services

[root@fedora ~]# chkconfig --list firstboot

firstboot 0:off 1:off 2:off 3:off 4:off 5:off 6:off

[root@fedora ~]#

 

NO.5 What is the main advantage of the Oracle Unbreakable Enterprise Kernel compared with the

Red Hat compatible kernel?

A. It is more secure and, therefore, more difficult to hack.

B. It has a lower Mean Time Between Failures.

C. It provides higher availability for applications by reducing Mean Time to Recovery.

D. It scales better for more CPUS, memory, and Infiniband network connections.

Answer: D

Explanation:

The Unbreakable Enterprise Kernel, for those who want to leverage the latest

features from

mainline Linux and boost performance and scalability.

The Red Hat Compatible Kernel, for those who prefer strict Red Hat kernel ABI (kABI)

compatibility.

C. env | grep SERVICE

D. env $SERVICE

NO.7 Which three settings can be controlled by using the chage breemar command as the root user,

to modify the parameters in the /etc/shadow file?

A. The expiration date of the breemar account

B. The number of days after the breemar account is locked, that it becomes expired

C. The maximum number of days that must elapse between password changes by the user breemar

D. The number of days after the breemar account is locked, that it becomes unlocked

E. The minimum number of days that must elapse between password changes by the user breemar

F. The maximum number of failed login attempts on the breemar account before the account is

locked

Answer: A,C,E

Explanation:

A: chage -E, --expiredate EXPIRE_DATE

Set the date or number of days since January 1, 1970 on which the

user's account will no longer be accessible.

CE: You need to use chage command to setup password aging.

The chage command changes the number of days between password changes

and the date of the last password change. This information is used by the system to determine

when a user must change his/her password.
