none of the above
To recover the root password, the user needs to boot the system using a boot disk floppy. Then, they need to mount the root partition and edit the /etc/passwd file to remove the root password. Option C is the correct answer.
Option A is incorrect because it does not provide any solution to recover the root password.
Option B is incorrect because it suggests to mount the main partition instead of the root partition. Editing the /etc/passwd file of the main partition will not affect the root password.
Option D is incorrect because it suggests to edit the /tmp/passwd file instead of the /etc/passwd file. The /tmp directory is used for temporary files, and editing the /tmp/passwd file will not affect the root password.
Option E is incorrect because it suggests to edit the /etc/passwds file instead of the /etc/passwd file. There is no such file as /etc/passwds, so this option is invalid.
The Answer is: C. Mount the root partition, edit the /etc/passwd file to remove the root password, reboot.

Users on your network cannot print to a Linux printer. You decide to restart the printer daemon, which command would achieve that?
-
topq printer-name
-
enable printer-name
-
restart printer-name
-
up printer-name
To solve this question, the user needs to know the basic command to restart a printer daemon in Linux.
Now, let's go through each option and explain why it is right or wrong:
A. topq printer-name: This option is incorrect because the command "topq" is not a valid command in Linux. It does not exist and cannot be used to restart a printer daemon.
B. enable printer-name: This option is incorrect because the command "enable" is used to enable a printer, not restart the printer daemon. It does not restart the printer daemon.
C. restart printer-name: This option is incorrect because the command "restart" is not the correct command to restart a printer daemon in Linux. The correct command to restart the printer daemon is "systemctl restart cups".
D. up printer-name: This option is incorrect because the command "up" is not a valid command to restart a printer daemon. It does not exist in Linux.
The correct answer is:
The Answer is: C. restart printer-name
Which file does Linux use to resolve hostnames?
-
/etc/hostname.conf
-
/etc/dns.conf
-
/etc/host.conf
-
/etc/resolve.conf
AI Explanation
To answer this question, you need to understand how Linux resolves hostnames.
Linux uses the /etc/host.conf
file to resolve hostnames. This file contains the configuration settings for the hostname resolution process.
Let's go through each option to understand why it is correct or incorrect:
Option A) /etc/hostname.conf
- This option is incorrect because Linux does not use the /etc/hostname.conf
file to resolve hostnames.
Option B) /etc/dns.conf
- This option is incorrect because Linux does not use the /etc/dns.conf
file to resolve hostnames.
Option C) /etc/host.conf
- This option is correct. Linux uses the /etc/host.conf
file to resolve hostnames. This file contains the configuration settings for the hostname resolution process.
Option D) /etc/resolve.conf
- This option is incorrect. While the /etc/resolve.conf
file exists in Linux systems, it is used to configure the DNS (Domain Name System) resolver, not for hostname resolution.
The correct answer is C) /etc/host.conf
. This option is correct because Linux uses the /etc/host.conf
file to resolve hostnames.

What is the DOS LPT1 port in Linux?
-
/dev/lpt0
-
/dev/lpt1
-
/dev/lp0
-
/dev/lp1
-
DOSLPT1
AI Explanation
To answer this question, we need to understand the concept of the DOS LPT1 port and its equivalent in Linux.
In DOS (Disk Operating System), LPT1 is a parallel port used for connecting printers or other parallel devices. In Linux, parallel ports are represented as device files under the /dev directory.
The correct answer is option C) /dev/lp0. In Linux, the equivalent device file for the DOS LPT1 port is /dev/lp0. This means that if you want to access the parallel port in Linux, you would use /dev/lp0 instead of LPT1.
Option A) /dev/lpt0 - This option is incorrect because the correct device file for the DOS LPT1 port in Linux is /dev/lp0, not /dev/lpt0.
Option B) /dev/lpt1 - This option is incorrect because the correct device file for the DOS LPT1 port in Linux is /dev/lp0, not /dev/lpt1.
Option C) /dev/lp0 - This option is correct because the device file /dev/lp0 is the equivalent of the DOS LPT1 port in Linux.
Option D) /dev/lp1 - This option is incorrect because the correct device file for the DOS LPT1 port in Linux is /dev/lp0, not /dev/lp1.
Option E) DOSLPT1 - This option is incorrect because the equivalent device file in Linux is not called DOSLPT1. In Linux, it is represented as /dev/lp0.
The correct answer is option C) /dev/lp0. This option is correct because it represents the equivalent device file for the DOS LPT1 port in Linux.
