The assessment test is an excellent way to test yourself before starting to study. It gives you an idea of where you should start and why.

In an assessment test, test your current skills from beginning to advance lever for any subject or topic to check “what do you know and from where you should start learning?”

Here I have put some basic questions for Linux assessment, so you can test your Linux skill and choose right path for Linux Learning.

 

Questions

1.    Which of the following are legal Linux usernames? [Select all that apply.]

  1. larrythemoose
  2. 4satish
  3. PamJones
  4. Samuel_Bernard_Delaney_the_Fourth

2.    What does the following command and its output reveal about the computer

$ ls –l /etc/localtime

Lrwxrwxrwx   1  root  root   10 Sep  15   12:05   /etc/localtime  ->  /usr/share/zoneinfo/US/Eastern

  1. The time zone is misconfigured; there is no /usr/share/zoneinfo/US/Eastern time zone file
  2. The computer’s security could easily be breached; this file should not have rwxrwxrwx permissions.
  3. The computer is configured to use the U.S. Eastern time zone as the local time.
  4. The current time in the U.S. Eastern time zone is 14.24 (2.24 PM).

3.    Why are groups important to the Linux user administration and security models?

  1. They can be used to provide a set of users with access to files without giving all users access to the files.
  2. They allow you to set a single login password for all users within a defined group.
  3. Users may assign file ownership to a group, thereby hiding their own creation of the file.
  4. By deleting a group, you can quickly remove the accounts for all users in the group.

4.    You’ve set your system (software) clock on a Linux-only computer to the correct time, and now you want to set the hardware clock to match. What command might you type to accomplish this goal?

  1. date –sethwclock
  2. ntpdate
  3. hwclock –utc –systohc
  4. time –set –hw

5.    An administrator types change –M 7 time. What is the effect of this command?

  1. The time account’s password must be changed at least once every seven days.
  2. All users must change their password at least once every seven days.
  3. All users are permitted to change their passwords at most seven times.
  4. The time account’s age is set to seven months.

6.    You’ve configured one computer on your five-computer network, ntp.linuxconcept.com, as an NTP server that obtains its time signal from ntp.example.com. What computer(s) should your network’s other computers use as their time source(s)?

  1. You should consult a public NTP server list to locate the best server for you.
  2. Both ntp.linuxconcept.com and ntp.example.com
  3. Only ntp.example.com
  4. Only ntp.linuxconcept.com

7.   What is wrong with the following /etc/passwd file entry? [Select all that apply.

4satish:x:529:Satish Kumar:/home/satish:/bin/passwd

  1. The default shell is set to /bin/passwd, which is an invalid shell.
  2. The username is invalid; Linux usernames can’t begin with a number.
