• Question 44:

  If forks is set to 100 and Ansible is run against an inventory of 50 servers, how many forks will Ansible create?

  A. 63
  B. 5
  C. 50
  D. 100
  C. 50

  ---

  Ansible will only spin up the number of forks that is necessary as long as it is less than the maximum allowed. In this case, the max is 100 so Ansible will make 50 forks to match the number of hosts target.

• Question 45:

  Which subcommand of ansible-galaxy makes a role available for use from galaxy?

  A. create
  B. pull
  C. init
  D. install
  D. install

  ---

  The install subcommand will pull a role from galaxy and make it ready for use on your local system.

• Question 46:

  State whether the following statement is true or false. A template has a maximum of 10 variables.

  A. True
  B. False
  B. False

  ---

  The No is much higher.

• Question 47:

  By default, how many times can a role be applied during a play?

  A. Once, no matter the parameters provided.
  B. As many times as necessary, no matter the parameters.
  C. Once, presuming it is only applied with a single set of parameters.
  D. As many times as necessary, presuming the `single_run' attribute is set to false.
  C. Once, presuming it is only applied with a single set of parameters.

  ---

  A role given only a single set of parameters will only be applied by Ansible one time in a play.

• Question 48:

  Which of the following is a good use case for an ad-hoc command? (Choose all that apply.)

  A. Experimenting with an Ansible Module
  B. Installing the netcat utility on application servers
  C. Checking the free memory on a particular group of hosts
  D. Upgrading a custom 3-tier application stack
  A. Experimenting with an Ansible Module
  B. Installing the netcat utility on application servers
  C. Checking the free memory on a particular group of hosts

  ---

  Installing netcat is a single yum command that would be easily run across a group of common servers with an Ansible ad-hoc command. A single command run against several servers is a perfect use case for an ad-hoc command. Writing a playbook would be overkill.

• Question 49:

  State whether the following statement is true or false. A template can only use 1 variable.

  A. True
  B. False
  B. False

  ---

  You can use multiple variables in templates.
