Key Concepts
For this test, you should understand the following terms and how they interrelate at a high level:
- processes: fork, zombie processes
- the UNIX shell (e.g., csh or bash)
- basic UNIX file permissions
- UNIX standard input & output, I/O redirection
- kernel & supervisor mode
- hypervisor and hypervisor mode
- paravirtualization and hardware virtualization
- /proc and basic output of ps
- UNIX Environment variables
- UNIX dynamic libraries versus system calls
- static versus dynamic linking
- output of ldd versus /proc/<PID>/maps
- VM guest additions
- virtualization versus emulation
Sample Questions
- If you see a zombie process during normal system operation, how can you get rid of it?
- Hypervisors multiplex computer hardware between what kind of programs?
- What CPU mode does the kernel run in?
- If a CPU does not support hardware virtualization, can you still run a hypervisor?
- Under hardware virtualization, when an interrupt happens, which runs first - a hypervisor or a kernel?
