Final answer:
The audit logs in systems like Microsoft 365 typically retain information for up to 90 days, allowing administrators to review system activities for security and compliance purposes.
Step-by-step explanation:
The question "For up to how many days can the audit log provide information?" pertains to the retention period of the audit log in a particular system or platform. While this may vary depending on specific systems, if we are referring to widely used platforms such as Microsoft 365 or other similar enterprise systems, the correct answer is typically c) 90 days. Most large-scale services with auditing capabilities keep logs for this length of time to allow administrators to review any changes, accesses, or transactions that have taken place and to maintain records for a given period for compliance reasons.
However, it's important to note that the retention period can be different based on the system or service in question, and should be verified against specific system documentation or service agreements.
