puppet configuration tool (devops)

i can explain clearily with in 10 min better we can connect 10 min we have 10 IP address (10 hosts) Given the above Hash existing in Hiera, write puppet code to return only the hostnames of the entries that are in the 'ess' host class. Bonus Guru Question: Write in Ruby a Custom Puppet Function that does the same thing as above, except the host class 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/[login to view URL] using a template (the contents of the template doesn't matter) c) Creates the file /etc/apache2/site-available/[login to view URL] 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/[login to view URL] 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.
