   An administrator is troubleshooting a performance issue on a BIG-IP ASM system. The CPU report shows that the 'TMM' cores are at 60% utilization, but the 'ASM security processing' context is at 55%. The memory report shows the 'Security Shared Memory' pool is at 95% utilization. Which of the following is the most likely bottleneck?

   • AThe ASM security processing is consuming most of the TMM CPU, and the high memory usage may be causing additional overhead
   • BThe system is memory-bound, and adding memory will fully resolve the issue
   • CThe logging subsystem is the bottleneck
   • DThe network I/O is the bottleneck

   An administrator wants to understand the workload on the ASM process. The 'process requests' metric shows a steady increase in the number of requests per second, but the average processing time per request is also increasing. What is the most likely interpretation of this trend?

   • AThe ASM policy is becoming less efficient over time
   • BThe logging configuration is causing delays in the process
   • CThe ASM process is becoming a bottleneck as the request rate grows, causing requests to take longer
   • DThe system is healthy and the increase is due to normal traffic growth

   If the process requests metric shows a sudden spike, what is the most likely interpretation?

   • AThe ASM is running out of memory
   • BThere is a sudden increase in traffic or a possible attack
   • CThe ASM is rebooting
   • DThe logging is disabled

   An administrator is analyzing the CPU report and sees that the 'TMM' cores are at 95% utilization, but the 'ASM security processing' context is only at 5%. The administrator wants to confirm that ASM is not the bottleneck. Which additional metric would best support this conclusion?

   • AThe memory report shows high utilization in the security shared memory pool
   • BThe logging context shows high CPU utilization
   • CThe process request metrics show a low queue length and stable processing time
   • DThe number of requests per second is increasing
