Which capability is primarily about reducing costs while maintaining performance?

• A. High service quality
• B. Low cost
• C. Deployability
• D. Diversity

Answer: (B)

The main concept here is cost efficiency: delivering the needed capability while minimizing expense. Reducing costs while maintaining performance is exactly what a low-cost approach aims for—achieving acceptable or required performance without overspending, effectively optimizing performance per dollar. The other capabilities focus on different priorities: high service quality centers on maximizing performance quality, which can drive up cost; deployability is about how easily the system can be deployed in various environments; and diversity is about having multiple options or redundancies to improve resilience. Since this item asks for balancing cost with maintaining performance, choosing the low-cost option best captures that cost-performance trade-off.
