   An e-commerce site is load tested. The results show that response times are stable up to 2000 concurrent users, but beyond that, they degrade linearly. The application server's CPU is at 60%, and the database server's CPU is at 30%. However, the network interface on the application server is at 95% utilization. The test was run on a 1 Gbps network. What is the most likely bottleneck?

   • AThe network bandwidth is the bottleneck, as the network interface is saturated.
   • BThe application server's CPU is the bottleneck, as it is the first resource to show high utilization.
   • CThe load generator is the bottleneck, as it cannot generate more than 2000 users.
   • DThe database server is the bottleneck due to connection limits.
