According to dynamic updates best practices, what is the recommended threshold value for content updates in a mission- critical network?

Palo Alto Networks’ content-update best-practice guide states that in mission-critical networks you should schedule the firewall to install an Applications-and-Threats dynamic-update only after the package has been available for at least eight (8) hours.

The eight-hour threshold balances operational safety—giving the vendor time to withdraw a faulty release—against the need to keep signatures current for high-value production environments.

B. 16 hours – Longer than the recommended 8-hour delay, needlessly postponing protection in a mission-critical environment.

C. 32 hours – Excessive delay; guideline for less-critical or staging networks, not mission-critical.

D. 48 hours – Conservative setting used for test or highly risk-averse networks, not the mission-critical best-practice value.
