NSE4_FGT-7.0 · Question #128

Which two configuration settings are synchronized when FortiGate devices are in an active-active HA cluster? (Choose two.)

The correct answer is C. NTP D. DNS. In an active-active HA cluster, critical configuration settings such as NTP and DNS are synchronized across FortiGate devices to maintain consistent network operations and services.

Why each option

In an active-active HA cluster, critical configuration settings such as NTP and DNS are synchronized across FortiGate devices to maintain consistent network operations and services.

AFortiGuard web filter cache

The FortiGuard web filter cache is typically specific to each cluster member and is not synchronized, as each member independently builds its cache based on the traffic it processes.

BFortiGate hostname

The FortiGate hostname is a unique identifier for each individual device and is not synchronized within an HA cluster; each member retains its distinct hostname.

CNTPCorrect

NTP (Network Time Protocol) settings are synchronized in a FortiGate HA cluster to ensure all members maintain consistent time, which is crucial for logging, certificate validation, and scheduled tasks.

DDNSCorrect

DNS (Domain Name System) server configurations are synchronized across HA cluster members to ensure all devices use the same DNS resolvers for internal lookups and external service access.
