1. Challenge

   Create and enable a swap partition using /dev/xvdg1.

   1. Use the mkswap command to create swap space on /dev/xvdg1:

   mkswap /dev/xvdg1

   2. Use the swapon command to enable the swap partition:

   swapon /dev/xvdg1

2. Challenge

   Add an entry to /etc/fstab to ensure that the swap partition persists though a reboot (use the UUID).

   Obtain the UUID for the partition using the blkid command:

   1. Use the editor of your choosing (i.e., vim, nano, etc.) to add an entry to /etc/fstab for the swap partition:

   vim /etc/fstab

   1. At the bottom of the file add the following entry:

   UUID=partition_UUID swap swap sw 0 0

3. Challenge

   Create and enable a 1 GB swap file in the root directory called "extraswap".

   1. Use the dd command to create a 1 GB file called extraswap:

   dd if=/dev/zero of=/extraswap bs=1M count=1024

   1. Update the permissions on the swap file to be read right only for the root user:

   chmod 600 /extraswap

   1. Use the mkswap command to turn extraswap into a swap file:

   mkswap /extraswap

   1. Use the swapon command to enable the swap file:

   swapon /extraswap

4. Challenge

   Add an entry to /etc/fstab to ensure that the swap file persists through a reboot (use the full path to the file name).

   1. Use the editor of your choosing (i.e., vim, nano, etc) to add an entry to /etc/fstab for the swap file:

   vim /etc/fstab

   1. At the bottom of the file add the following entry:

   /extraswap swap swap sw 0 0
