1) Given the above Hash existing in Hiera, write puppet code to return only the hostnames of the entries that are in the 'ess' hostclass.

Bonus Guru Question: Write in Ruby a Custom Puppet Function that does the same thing as above, except the hostclass to be searched for is passed as an argument.

2) Given an Array variable with hosts from #1 and using Puppet code how would you change each element in the array to look like: http://<hostname>:8080

3)  Write a quick module that accomplishes the following tasks.

  a) Installs Apache2

  b) Creates the file /etc/apache2/apache2.conf using a template (the contents of the template doesn't matter)

  c) Creates the file /etc/apache2/site-available/www.conf from a file in the module (the contents of the file doesn't matter)

  d) Links the file in c) to /etc/apache2/site-enabled/www.conf

  e) Restarts apache if any of these files changes.

4) Given a hostname pattern of 'host-<company>-<hostclass>-<index>' (i.e. host-apple-puppet-0) write a custom fact that extracts the <company> value and assigns it to the variable 'company' in facter.
