B. chroot
C. grep
D. sudo
View Answer
Ans : B
Explanation: The concept of containerization in operating systems has its roots in the 1970s and 1980s, with the creation of the "chroot" command on Unix systems.
2. ___________ used kernel features such as namespaces and cgroups to isolate processes from one another.
A. BXC
B. PCE
C. LXC
D. ZYE
View Answer
Ans : C
Explanation: LXC used kernel features such as namespaces and cgroups to isolate processes from one another, and provided the foundation for modern containerization technology.
3. Containers are?
A. lightweight
B. portable
C. Both A and B
D. None of the above
View Answer
Ans : C
Explanation: containers are lightweight and portable.
4. Containerization in an operating system also allows for better security, as containers are isolated from one another and from the host operating system, reducing the potential attack surface.
A. TRUE
B. FALSE
C. Can be true or false
D. Can not say
View Answer
Ans : A
Explanation: True, Containerization in an operating system also allows for better security, as containers are isolated from one another and from the host operating system, reducing the potential attack surface.

D. A pre-packaged version of an application and its dependencies
View Answer
Ans : D
Explanation: A container image is a pre-packaged version of an application and its dependencies
8. Which of the following is the difference between a container and a virtual machine?
A. Containers share the host operating system kernel while virtual machines have their own kernel
B. Containers are more lightweight than virtual machines
C. Virtual machines provide better isolation than containers
D. All of the above
View Answer
Ans : D
Explanation: All of the above is the difference between a container and a virtual machine.
9. What are the advantages of using containerization in an operating system?
A. Portability
B. Security
C. Complexity
D. All of the above
View Answer
Ans : A
