A BIG-IP administrator is troubleshooting a memory issue on a system with 32GB of RAM. The 'free -m' output shows: total=32768, used=29000, free=500, shared=100, buff/cache=3268, available=3700. The administrator also runs 'top' and sees that the tmm process is using 25GB of memory. The system is configured with 100 virtual servers and 1000 pools. What is the most likely explanation for the high memory usage?

The system is swapping, which is causing the high memory usage.

The system is under-provisioned for the configuration and needs more RAM.

The tmm process has a memory leak and needs to be restarted.

The tmm process is using memory as expected for the number of configured objects, and the system is adequately sized.

A BIG-IP administrator runs 'free -m' and sees the following output: total used free shared buff/cache available Mem: 8000 7500 200 100 300 400 What does the 'available' value of 400 MB indicate?

The system has 400 MB of memory that is used by the TMM processes

The system has about 400 MB of memory that can be allocated to new processes without swapping

The system has 400 MB of memory that is used for swap space

The system has 400 MB of memory that is permanently reserved for the kernel

An administrator runs 'free -m' on a BIG-IP and sees: total=32768, used=31000, free=100, shared=50, buff/cache=1668, available=1700. The system is running slowly. What is the most accurate interpretation of this memory utilization data?

The system is healthy because the used memory is normal for a BIG-IP.

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

The system is under severe memory pressure, as only 100MB is free and available memory is low.

The system has plenty of memory available because buff/cache can be reclaimed.
