NOTE: If you have the new question on this test, please comment Question and Multiple-Choice list in form below this article. We will update answers for you in the shortest time. Thank you! We truly value your contribution to the website.
1. A system administrator issues the apt-get upgrade command on a Linux operating system. What is the purpose of this command?
Every application installed will update itself to the latest version.
Operating system updates are downloaded and will be installed.
The remote repository of applications and dependencies will be updated to the latest version.
A specific application named upgrade will be installed.
Explanation: When the apt-get upgrade command is isued in a Linux terminal, all installed applications will attempt to upgrade to the latest version available.
2. A Linux system administrator is searching the passwd file for any username that starts with a digit. Which grep command should the administrator use?
grep ‘(0-9}’ /etc/passwd
grep ‘[0-9]’ /etc/passwd
grep ‘_[0-9]’ /etc/passwd
grep ‘^[0-9]’ /etc/passwd
Explanation: The grep Linux command can be used to process text line by line and to print any lines which match a specified pattern. The matching patterns are based on regular expression (regex) query modifiers used to select the appropriate content. Some regex query modifiers are as follows:
_ (underscore): matches a space
^ (caret): indicates the start of a string
$ (dollar sign): indicates the end of a string
. (period): matches a single character, including a space
* (asterisk): matches zero or more occurrences of the preceding character
[ ] (square bracket): matches a character
{ } (curly bracket): repeats preceding character
3. What is the output when the following code is entered into a Python program interpreter?
[1,2,4,5] + [3,6]
[1,2,3,4,5,6]
[12]+[9]
[21]
[1,2,4,5,3,6]
Explanation: The Python interpreter performs concatenation of two lists without reordering the list elements
4. What is displayed after the following code is entered into a Python interpreter?
addition = 22 +10
print(addition)
nothing ( because the print command is wrong)
[22]+[10]
(syntaxerror)-…as there should not be a space between the numerical values
32
Explanation: The Python interpreter will perform the operation and display the result, 32.
5. A Linux administrator is attempting to use a terminal to configure the network interface card on a computer. The administrator receives a message that the administrator does not have necessary permissions to perform the configuration. What should be done prior to the configuration command?
identify a different network interface
use a different user account
use the sudo command
change the chmod permissions on the network configuration file
Explanation: Multiple terminal commands require the use of the sudo command as a preface. The command sudo means “super user do”. Sudo will require an administrator password be entered to complete a configuration. Malicious software usually cannot do damage on its own without knowing the password first.
6. A network engineer needs to review the status of all network interfaces of a server running a Linux operating system. The engineer enters the command ifconfig -a. What is the resuit of this command?
All active interfaces will display information.
The ARP table of the computer will be displayed.
Both active and inactive interfaces will display information.
The host routing table will be displayed.
Explanation: The ifconfig command with the -a modifier will provide information for all network interfaces, even if they are down.
7. A system administrator attempts to determine what is causing a computer to perform slower than normal. The administrator issues the ps command. What is displayed by this command?
current RAM usage
current NIC status
active processes using CPU time
current HDD usage
Explanation: The ps command can be combined with multiple modifiers to display all processes running on a computer, view a specific process, or end processes that are using CPU time.
