A server is experiencing memory exhaustion, and you notice that the system is swapping heavily. Which initial troubleshooting step is most appropriate to identify which processes are consuming the most memory?

Use the df command to check disk space

Use the iostat command to check I/O statistics

Use the top command and sort by memory usage

Use the netstat command to check network connections

A multi-tenant server hosts two applications: App A (CPU-intensive) and App B (I/O-intensive). `mpstat -P ALL 1` shows Core 0 at 100% and Core 1 at 10%. `iostat -x` shows the disk at 80% utilization. The administrator wants to improve overall throughput. Which action is most effective?

Increase the disk's read-ahead buffer to improve I/O efficiency

Move App B to a different server to eliminate I/O contention

Pin App A to Core 1 and App B to Core 0 using `taskset`

Use `cgroups` to limit App A's CPU quota and App B's I/O bandwidth
