Question

An administrator configures a preemptive active-passive high availability (HA) pair of firewalls and configures the HA election settings on firewall-02 with a device priority value of 100, and firewall- 01 with a device priority value of 90. When firewall-01 is rebooted, is there any action taken by the firewalls?

Options

  • ANo - Neither firewall takes any action because firewall-01 cannot be rebooted when configured
  • BNo - Neither firewall takes any action because firewall-02 is already the active-primary member.
  • CYes - Firewall-02 takes over as the active-primary firewall; firewall-01 takes over as the active-
  • DYes - Firewall-02 takes over as the active-primary firewall; firewall-02 remains the active-primary

Explanation

In a preemptive active-passive HA setup, the firewall with the higher device priority (lower numerical value) becomes the active-primary member once it becomes functional. When firewall- 01 (priority 90) is rebooted, firewall-02 (priority 100) temporarily takes over as the active-primary member. After firewall-01 finishes rebooting and becomes fully operational, it preempts firewall-02 and takes over as the active-primary member, following the preemptive configuration.
