What are Solaris interview questions and answers?

Here are several of the basic interview questions for Solaris:

Question:

Explain the boot process of Solaris operating system?

Answer:

Boot process is divided into four phases:

• * POST – Power On Self-Test, it will detect hardware, machine host ID, serial number, architecture type, memory, and Ethernet address and loads the primary program called bootblk.
• * OBPROM – Open Boot Programmable:
  1. ** Diagnose the entire system hardware and memory
  2. ** Initialize the boot parameter
  3. ** Create device trees and load the boot block from 0-15 sector, which is called secondary boot programmable ufsboot.
• * KERNEL INITIALIZATION – ufsboot loads the kernel (generic unix) then kernel loads all the necessary devices modules to mount the root partition to continue the booting process.
• * INIT PHASES – it starts by executing /etc/init program and start other process reading the /etc/inittab files, as the directory in the /etc/inittab files.

Question:

What is the difference between init 1 and init s?

Answer:

If you switch from multiuser mode to init s and then switch back to multiuser mode, the remote users automatically reconnects to the system. Whereas in the case of init 1, they have to reconnect manually which means they need to re-login.
