Question 1

Which step helps confirm whether an undefined variable error is caused by Hiera’s data hierarchy?

Options :

A : Disable environment merges in Hiera so only the top-level data is used

B : Move the variable from Hiera into node classification statements

C : Manually override the variable in the class definition

D : Temporarily set a default value for the lookup() call and check logs

Answer: D

Question 2

How might you securely tune Puppet’s configuration to handle multiple agent runs from an SSL standpoint?

Options :

A : Using certificate revocation lists, ensuring only valid agent certs are trusted

B : Disabling SSL entirely to simplify the handshake

C : Relying on environment merges that unify node keys

D : Storing agent keys in a public Git repository for easy distribution

Answer: A

Question 3

You use puppet apply --noop to preview changes, but it fails with an undefined variable error for a parameter that you know is set in production. Which factor might explain why the variable is missing in a no-op test environment?

Options :

A : The production environment data from Hiera or node classification may not be loaded in a local apply

B : puppet parser validate must be used to load environment variables automatically

C : The variable references a built-in function that’s disabled in no-op mode

D : Variables are only valid if you run in a fully enforced mode

Answer: A

Question 4

After an update, Puppet logs indicate “Evaluation Error: Unknown function.” Which root cause is likely?

Options :

A : The function call is valid, but puppet parser validate is misreading it

B : Environment locking prevents calling the function if the node classification changed

C : The built-in Puppet function was renamed in the latest version

D : A third-party module’s function was removed or not loaded in the current environment

Answer: D

Question 5

A newly published module has a tests/ directory with example usage files. You notice they lack any references to your environment or Hiera data. How should you leverage those .pp test files effectively?

Options :

A : Merge all test code into the module’s init.pp so it runs automatically in every puppet run

B : Run them locally as demonstration scenarios, adjusting them to reflect your environment or Hiera references

C : Delete the tests/ directory to avoid confusion with production code

D : Immediately deploy them in production without modification, as test manifests are always safe

Answer: B
