1. What two commands show the status of processes in a Linux system?

Explanation

The correct answer is ps and top. The "ps" command is used to display information about active processes in a Linux system, such as their process ID, CPU and memory usage, and status. The "top" command, on the other hand, provides real-time information about the system's processes, including CPU and memory usage, as well as other system statistics. Both commands are commonly used to monitor and manage processes in a Linux system.

2. What is the name of the file that contains information about direct memory access channels and the devices associated with them? (give the full path)

Explanation

The correct answer is "/proc/dma" because in the Linux operating system, the "/proc/dma" file contains information about the direct memory access (DMA) channels and the devices that are associated with them. This file provides a way for users and programs to access and manipulate DMA-related information and settings.

Submit
3. You are working with your hardware vendor's technical support people to troubleshoot a network card problem. The technical support representative wants to know which IRQ channel the card is using. Which file would tell you the IRQ channel for the card?

Explanation

The correct answer is A, /proc/interrupts shows IRQ lines and the devices using them. Answer B is incorrect because /proc/ioports will give the base address for the NIC card, not the IRQ. Answers C and D both refer to nonexistent files.

Submit
4. Management has finally approved the budget for you to buy your first high-capacity SCSI tape drive and SCSI host adapter. You install the host adapter in PCI slot 4 and set the tape drive's SCSI ID to 5. What Linux device would you use to access the new tape drive?

Explanation

The correct answer is A, /dev/st0. Answer B is incorrect because /dev/st1 refers to the second SCSI tape drive and the question states that this is the first SCSI tape drive. Answers C and D are trying to trick you into thinking that the the device number is determined by the PCI slot number or the SCSI ID, but this is not the case.

Submit
5. You are providing telephone support to a novice user at a remote location, because the dial-in modem is not working. When you ask the user to tell you what port the modem is connected to he says, "COM1." What is the Linux device that corresponds to COM1? (provide the full path)

Explanation

The correct answer is /dev/ttyS0. Remember that Linux numbers devices starting from zero.
