Question 1

After configuring a new kernel, what file under /usr/src/linux/ contains the configuration?
Solution:
/usr/src/linux/.config, .config

Does this meet the goal?

Yes

Question 2

What is the purpose of an initramfs during the Linux system start?

It loads required modules and starts sub sytems like LVM to make the root file system accessible to the kernel

It moves the kernel from normal system memory to initram memory to speed up kernel access

It copies the root file system’s content to RAM to speed up the system and reduce writes to disk

It creates a ram disk to store volatile data for directories like /tmp to reduce writes to disk

Question 3

A web application server contains 64GB of RAM and two swap partitions on normal hard disk drives, each with a size of 64 GB. Within the last month, the average number of user sessions on this server has grown by 20 percent. At the same time, the average usage of RAM increased from 65 to 75 percent, while the swap space is almost not used at all. It is expected that the number of user sessions will continue to increase by about 15 to 20 percent each month. Which of the following reactions would be appropriate in response to these observations? (Choose two.)

Delay any hardware upgrade until there is a significant consumption of swap space to ensure an efficient usage of the available hardware

Create a RAID 1 device on the two swap partitions to avoid data loss in case swap space has to be used in the future

Consider the installation of an additional application server to distribute the load if the expected growth continues over several months

Move the web application’s scripts and content a ram disk in order to ensure fast access and to avoid the need for swap space

Update the hardware to increase the amount of available RAM to avoid using swap space

Question 4

Considering the following kernel IP routing table below, which of the following commands must be used to remove the route to the network 10.10.1.0/24? (Select TWO answers)
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
203.0.113.162 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0
172.16.87.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0

127.0.0.0 0.0.0.0 255.0.0.0 U 0 0 0 lo
0.0.0.0 203.0.113.162 0.0.0.0 UG 0 0 0 ppp0

ip net delete 10.10.1.0/24

route del 10.10.1.0/24

route del -net 10.10.1.0/24

route del 10.10.1.0/24 gw 192.168.246.11

ip route delete 10.10.1.0/24

Question 5

According to the Filesystem Hierarchy Standard (FHS), what is the path to the Linux kernel source and may be a symbolic link to the real Linux source code? (Please specify the full path with no version information.)
Solution:
/usr/src/linux, /usr/src/linux/

Does this meet the goal?

Yes

Question 6

After a lot of write operations, the administrator want to ensure that the kernel flushes the file system buffers to disk. Which command will accomplish this? (Specify ONLY the command without any path or parameters.)
Solution:
sync

Does this meet the goal?

Yes

Question 7

Which is the main configuration file for the SystemV init process? (Specify the full name of the file, including path.)
Solution:
/etc/inittab

Does this meet the goal?

Yes

Question 8

After the downloading patch-4.6.4.xz from http://kernel.org, what are the next steps to prepare the build of a version 4.6.4 Linux kernel? (Choose two.)

Uncompress the file and move the resulting directory to /usr/src/linux

Apply the patch file to the kernel source directory containing kernel version 4.6.0

Apply the patch file to the kernel source directory containing kernel version 4.6.3

Uncompress the file using xz to get the uncompressed patch file

Use patch to apply the uncompressed patch file to the source directory of any previous kernel version

Question 9

After installing a compiled kernel, it can not find any modules that are needed to be loaded. What make target was likely missed while installing the kernel?
Solution:
make modules_install, modules_install

Does this meet the goal?

Yes

Question 10

What is the minimum number of disks required in a fully redundant RAID5 array?

Question 11

Which of the following terms are used to describe 3.x kernel releases? (Choose TWO correct answers.)

beta

final

longterm

prerelease

stable

Question 12

What is the meaning of the /etc/auto.home file?

It has the indirect maps for the mounting of file systems.

It has configuration information, such as passwords and keys, for the remote file server.

It has configuration information on settings for the /home mount point.

It is the holds the SSL key to allow authentication to the remote file server.

Question 13

Which of the following commands can be used to list IPv4 addresses and MAC addresses for IP devices that the system has seen on the local network?

arp

ifconfig

ipadm

iwlist

Question 14

What is a key difference between a zImage and bzImage kernel image?

zImage is compressed using gzip, bzImage is compressed using bzip2.

zImage is for 2.6 series kernels, bzImage is for 3.x series kernels.

zImage is limited to 64k, bzImage has no such restriction.

zImage gets loaded completely into low memor

bzImage will load into high memory once low memory is full.

Question 15

How can the label root be added to the ext2 filesystem on /dev/sda1?

relabel /dev/sda1 root

tune2fs -L root /dev/sda1

echo 'root' > /proc/fs/sda1/label

labelfs --device /dev/sda1 root
