Exam NGFW-Engineer Topic 1 Question 14 Discussion

Actual exam question for Palo Alto Networks's NGFW-Engineer exam
Question #: 14
Topic #: 1
A network security engineer at a 24/7 online retailer is upgrading an active/passive high availability (HA) cluster of PAN-OS firewalls. The primary goal is to perform the upgrade with no service interruption to online transactions. The engineer has already downloaded the new software to both devices.
Which sequence of actions will meet this requirement?

Suggested Answer: B Vote an answer

Upgrading the passive firewall first ensures there is no impact to live traffic. After the passive device is upgraded and operational, a controlled failover is performed so traffic moves to the upgraded firewall, and then the remaining firewall can be upgraded, achieving a zero-downtime upgrade process for an active/passive HA pair.
