If a content management system (CSM) is implemented, which one of the following would occur?

A CMS does not guarantee that test and production systems run identical software versions; in fact, test environments may intentionally run newer or different versions to validate changes before promotion.

A CMS controls how changes are deployed but does not inherently guarantee that applications placed into production are secure, as security depends on the code quality, testing, and security review processes themselves.

A core security principle of a CMS is enforcing separation of duties and least privilege by restricting developer access to production environments. Changes must be formally reviewed, approved, and promoted through a controlled pipeline (dev → test → production), preventing unauthorized or accidental modifications to live systems by developers.

A CMS introduces formal change control processes that typically add approval steps and documentation requirements, which can slow down patching rather than accelerating it.
