A BIG-IP administrator is troubleshooting a performance issue on a system with 64GB of RAM. The 'free -m' output shows: total=65536, used=60000, free=1000, shared=200, buff/cache=4536, available=5500. The administrator also notices that the swap usage is 0%. The system is running slowly. What is the most likely cause of the performance issue?

The system is swapping heavily, which is causing the slowdown.

The disk is full, causing the system to slow down.

The system has a hardware issue with the RAM modules.

The system is under memory pressure, and the kernel is aggressively reclaiming memory, causing performance degradation.

A BIG-IP administrator runs 'df -h' and sees that the /var filesystem is at 98% capacity. Which potential issue is most likely to arise?

Log files may fail to be written or rotated

Memory usage will increase automatically

Network throughput will be reduced

The system will immediately reboot
