What are the two cluster modes available in FortiAnalyzer HA?

The correct option highlights that the two cluster modes available in FortiAnalyzer for high availability are high availability and standalone.

In the context of FortiAnalyzer, high availability (HA) refers to a mode where multiple FortiAnalyzer devices work together to ensure continuous uptime and reliability in data collection and analysis. This setup allows for automatic failover in the event one device encounters issues, thus enhancing the system's resilience.

On the other hand, the standalone mode indicates that the FortiAnalyzer operates independently without any clustering features or redundancies in place. This mode is typically used in scenarios where high availability is not needed, allowing for simpler configuration and monitoring.

This understanding is critical for network administrators or security professionals looking to implement or manage FortiAnalyzer solutions, as it directly impacts system performance, reliability, and complexity in various operational environments.
