Question 1

Several masters share a single PuppetDB instance. A spike in fact storage causes massive load on the DB, slowing down all catalog compiles. Investigations show a node group producing exceptionally large fact sets. Which advanced approach curbs DB load without losing crucial data for the rest of the infrastructure?

Options :

A : Configure a fact blacklist or truncation for particularly large facts from those nodes, or use a specialized approach that reduces certain fact payload sizes before storing in PuppetDB

B : Merge environment data so fewer nodes produce facts daily

C : Lower concurrency globally to slow all agents so the DB can handle large facts

D : Convert all large facts to ephemeral environment merges ignoring the DB

Answer: A

Question 2

Why is it advisable to include environment-specific Hiera hierarchies for large-scale code usage across dev, test, and prod?

Options :

A : So that all environment data merges into a single universal set of configuration values

B : It merges everything at top scope, ignoring local environment differences

C : It allows each environment to override or provide unique data (credentials, settings) without affecting other environments

D : It prevents environment merges from referencing production code

Answer: C

Question 3

If you notice frequent collisions between two teams’ changes in the same module but different environments, what environment-based best practice could mitigate these collisions?

Options :

A : Force all changes into a single environment to avoid branching errors

B : Disable version control merges for that module, forcing local manual updates

C : Rely on puppet-lint to unify both teams’ changes automatically

D : Each team uses a dedicated dev environment or feature branch for changes, merging them only after they’re tested, preventing direct collisions on the main environment

Answer: D

Question 4

Why would you store static configuration files in the files/ directory of a Puppet module?

Options :

A : They can be served directly to nodes without modification, simplifying file distribution

B : They allow custom Ruby code execution inside manifest files when referencing them

C : They block other directories from referencing the same file content

D : They become automatically converted into EPP templates by Puppet during compilation

Answer: A

Question 5

Which Puppet Forge metadata element can reveal external modules or libraries you must install for the main module to function?

Options :

A : The requirements or dependencies list in the metadata file

B : The user reviews rating field

C : The module’s tags section providing descriptive keywords

D : The script logs recorded in the module’s readme
