Question 22

How can the kernel parameter for the maximum size of the shared memory segment (shmmax) be changed to 2GB (2147483648 Bytes) on a running system? (Choose TWO correct answers.)

Edit /etc/shmmax and set the parameter to 2147483648.

sysctl shmmax=2147483648

sysctl kernel.shmmax=2147483648

echo 2147483648 > /proc/sys/kernel/shmmax

export kernel.shmmax=2147483648

Question 26

What is a key difference between a zImage and bzImage kernel image?

zImage is compressed using gzip, bzImage is compressed using bzip2.

zImage is for 2.6 series kernels, bzImage is for 3.x series kernels.

zImage is limited to 64k, bzImage has no such restriction.

zImage gets loaded completely into low memory. bzImage will load into high memory once low memory is full.
