What is Zscaler's rotation policy for intermediate certificate authority certificates?

Intermediate CA rotation reduces exposure if a certificate were mishandled and keeps the inspection trust chain short-lived. Zscaler's rotation model for intermediate CA certificates uses a short validity window rather than long-lived static certificates. Option C (Certificates are rotated every seven days and have a 14-day expiration) is correct because the tested rotation policy is seven-day rotation with a fourteen-day expiration.

Why the other options are incorrect:

A. Certificates are rotated every 90 days and have a 180-day expiration: Ninety-day rotation and 180-day expiration would leave intermediate certificates active much longer than the Zscaler inspection model described here.

B. Lifetime certificates have no expiration date: Lifetime certificates would never expire, which is the opposite of good inspection-certificate hygiene. Zscaler uses short-lived intermediate certificates.

D. Certificates are issued dynamically and expire in 24 hours: A 24-hour expiration would be unnecessarily short and is not the documented intermediate CA timing in this exam item.
