If aggregation is enabled, which statement about permission calculation across directories is true?

• A. Permissions are taken from the first directory.
• B. Permissions are taken from the last directory.
• C. Permissions are aggregated from all directories.
• D. Permissions are randomly assigned.

Answer: (C)

Aggregation across directories means you combine permission information from each directory to determine the final access rights. When aggregation is enabled, you don’t rely on a single directory’s permissions; you merge the rights defined in all relevant directories. Therefore, the final permission set reflects permissions from all directories (typically the union of allowed rights). This is why the statement that permissions are aggregated from all directories is the accurate one. If you only used the first or last directory, or treated it as random, access would not reflect the full set of granted rights across the directories. For example, one directory may allow read and another may allow write, so aggregation would yield both read and write permissions.
