NSE 6 – FortiMail 6.2 — Question 1

Which firmware upgrade method for an active-passive HA cluster ensures service outage is minimal, and there are no unnecessary failovers?

Answer options

• A. Break the cluster, upgrade the units independently, and then form the cluster
• B. Upgrade both units at the same time
• C. Upgrade the standby unit, and then upgrade the active unit
• D. Upgrade the active unit, which will upgrade the standby unit automatically

Correct answer: B

Explanation

Answer B is correct because upgrading both units at the same time prevents any service outage by ensuring that both units are upgraded together without needing to switch roles. The other options either require breaking the cluster or upgrading one unit at a time, which can lead to potential service interruptions or unnecessary failovers.
