What would most likely be a reason for configuring a FortiAnalyzer in HA mode?

Configuring a FortiAnalyzer in High Availability (HA) mode is primarily done to provide redundancy and ensure high availability. In a network environment, continuous access to logs and data analysis is crucial for effective security monitoring and incident response. By utilizing HA, organizations can deploy multiple FortiAnalyzer appliances that work in tandem, so if one fails, the other can immediately take over. This minimizes potential downtime, maintains system reliability, and enhances the overall resilience of the network infrastructure.

When implementing HA, if one device experiences a failure or maintenance is required, the service continues uninterrupted, allowing for seamless operational functionality. This is particularly important for businesses that depend on real-time data and must avoid any interruptions to their security monitoring workflows.

Other options, while relevant to overall system management or performance, do not specifically capture the primary objective of HA configurations in the context of FortiAnalyzers. Increasing performance may not be a direct outcome; rather, it focuses on availability and reliability. Similarly, while HA can somewhat aid in cost-saving through more effective resource usage, its main intention isn't to reduce deployment costs. Finally, HA setups tend to add complexity rather than simplify management tasks due to the need for additional configuration and monitoring of the multiple devices involved.
