A developer created a custom metadata profile and assigned default values to some fields.

When a new metadata profile is applied to a folder in AEM, itonly affects new assetsadded to that folderafterthe profile is applied. Existing assets that were already in the folder or subfolders prior to the profile being assigned will retain the metadata profile that was previously applied.

To update the metadata of existing assets with the new profile, you would need to either manually update the assets or run a script to reapply the metadata profile to those assets.

Option B is incorrect because the profile applies to all assets in the folder, not just direct children. Option C is incorrect because if there were invalid field values, you would likely see an error or warning, rather than a silent failure.
