200-201 Practice Question: Has implemented a security policy requiring all…
An organization has implemented a security policy requiring all employees to change their passwords every 90 days. Which security goal does this policy primarily support?
⚠ Common exam trap
Cisco often tests the distinction between confidentiality and integrity by presenting password policies as a control for data modification, when in fact password rotation primarily limits the exposure of stolen credentials, directly supporting confidentiality.

Correct answer & explanation
✓
Confidentiality
Requiring password changes every 90 days primarily supports confidentiality by reducing the window of opportunity for an attacker to use a compromised credential. If a password is stolen or guessed, the mandatory rotation ensures that the stolen credential becomes invalid after 90 days, limiting unauthorized access to sensitive data. This directly aligns with the confidentiality goal of preventing disclosure to unauthorized parties.
