You want to ensure a macro is only available to a specific user role. Where do you configure this restriction?
Macro permissions are controlled through the macro object's own permissions setting, where you assign read or write access to specific roles. Editing that setting restricts visibility so only the intended user role can invoke the macro.
Why this answer
Macro permissions in Splunk are controlled through the object's permission settings, accessible via Settings > Advanced Search > Search Macros (or the macro's Permissions link). You can set the macro to be private, shared in the app, or shared globally, and you can specify which roles have read or write access. This is the standard way to restrict a macro to a specific role.
Exam trap
SPLK-1004 often tests where macro permissions are configured, and candidates who think permissions are set in macros.conf or in the macro definition itself rather than in the object's permission settings pick the wrong answer.
How to eliminate wrong answers
Option A is wrong because user account profiles do not control macro access; permissions are role-based, not user-based. Option C is wrong because manually editing macros.conf is not the recommended way to set permissions — permissions are stored in metadata files (default.meta), not macros.conf. Option D is wrong because macros.conf does not support a 'role' parameter in the macro definition; access control is handled via metadata, not the definition stanza.
