What is an effective method for optimizing the EPS (Events Per SeconD. performance in IBM Security QRadar SIEM V7.5?

Question

Options

• ATuning the system based on monitored EPS trends and peak values
• BIncreasing the EPS limit arbitrarily without assessing system impact
• CAssigning EPS values based on the color intensity of events
• DSetting uniform EPS thresholds for all event categories

• A
  84% (27)
• B
  3% (1)
• C
  3% (1)
• D
  9% (3)

Explanation

Tuning QRadar based on monitored EPS trends and peak values (A) is correct because effective SIEM performance management requires data-driven decisions - you observe actual event throughput patterns over time, identify bottlenecks at peak load, and adjust license allocations, parsing rules, and flow configurations accordingly. B is wrong because arbitrarily increasing EPS limits without impact assessment wastes license capacity and can destabilize the system. C is nonsensical - color intensity has no bearing on EPS allocation in any SIEM context. D is wrong because different event source types (firewalls, endpoints, cloud services) generate vastly different event volumes, so uniform thresholds lead to over-allocation in some areas and throttling in others.

Memory tip: Think "Monitor before you Modify" - the word tuning implies a feedback loop: measure first, then adjust. Any answer that skips the measurement step (B, C, D) is wrong by definition.
