Free OSCP Linux Questions and Answers

Question 1

How should a lengthy command that has been piped numerous times and contains multiple instructions be executed in the background?
Answer: It must be enclosed in parenthesis, and at the end, the & must appear outside the parenthesis (commands; commands | commands) &.

Accepted Answer

TRUE

Answer

To execute a lengthy command pipeline or sequence of commands in the background in Linux, the entire sequence must be grouped together. This is achieved by enclosing the commands in parentheses `()` and then appending an ampersand `&` outside the closing parenthesis. This ensures that all commands within the pipeline or sequence are treated as a single job and sent to the background, allowing the terminal to be used for other tasks.

Question 2

What makes using -p with netstat unique?
Answer: Like echo, it lets you print to the screen, except it writes actual text rather than ignoring single and double quotes. Additionally, you may use it to input a line of instructions into an application like ssh or cat.

Accepted Answer

FALSE

Answer

The description provided for `netstat -p` is incorrect. The `netstat -p` command is used to display the PID (Process ID) and program name associated with each network connection. It does not function like `echo` for printing text or for inputting instructions into applications; its purpose is specifically to provide process information related to network sockets.

Question 3

Where .so (Library file, stands for "shared object") are stored (basically like Windows .dll files).

Accepted Answer

/lib

Answer

In the Linux file system hierarchy, the `/lib` directory (or `/usr/lib` for non-essential libraries) is where shared libraries, often ending with the `.so` extension (shared object), are stored. These files are analogous to `.dll` files in Windows and contain code that can be used by multiple programs, allowing for efficient resource sharing and modularity across the system.

Question 4

Linux file system that is virtualized and gives you access to the kernel's perspective

Accepted Answer

/proc

Answer

The `/proc` file system in Linux is a virtual file system that provides a dynamic interface to the kernel's internal data structures and processes. It doesn't contain traditional files but rather real-time system information, including details about running processes, kernel parameters, and hardware. This allows users and programs to access the kernel's perspective and monitor system status.

Question 5

The location of the log files.

Accepted Answer

/var/log

Answer

In the Linux file system, the `/var/log` directory is the standard location for storing system and application log files. These logs contain records of system events, errors, warnings, and other operational data, which are crucial for troubleshooting, security auditing, and monitoring system performance. This centralized location helps administrators manage and review system activity efficiently.
