Which statement about environment placeholders in Anypoint Platform is true?

• A. They enable environment-specific values to be injected at deployment time without code changes.
• B. They require a separate code base for each environment.
• C. They are used only for security configurations.
• D. They are deprecated in Mule 4.

Answer: (A)

Environment placeholders let you externalize configuration so a single app artifact can run in multiple environments with different values. In Mule 4, you reference values like ${property.name} in your config, and at deployment time Anypoint Platform provides environment-specific values to replace those placeholders. This means endpoints, credentials, and other settings can vary by environment without changing the code.

That’s why this statement is true: you inject environment-specific values at deployment time without modifying the application code. It’s not about creating separate code bases, it isn’t limited to security configurations, and it isn’t deprecated—placeholders are a standard way to externalize configuration across environments.
