A system administrator needs to determine whether a server's CPU usage spikes at a specific time each day. The server has been running for three weeks, but no monitoring was configured at deployment time. Which approach will provide the needed historical data?

Check `/var/log/sysstat` or `/var/log/sa` for existing `sar` data collected by the sysstat cron job

Run `sar -u -f /var/log/wtmp` to extract CPU usage from the login records

Use `mpstat -P ALL 60` and leave it running for 24 hours to capture the daily pattern

Use `atop -r` to replay the last three weeks of process activity from the kernel ring buffer

A server's load average is 12 on a 4-core system. `top` shows multiple processes in 'R' state. `mpstat -P ALL 1` shows all cores at 100% user time. `iostat -x` shows the disk at 5% utilization. `free -m` shows 4 GB available. Which action is most appropriate to reduce the load?

Replace the disk with a faster SSD

Increase the process priority of the running applications

Add more CPU cores to the server

A web server's response time has degraded over the past hour. `free -m` shows: total=16384, used=15800, free=584, shared=120, buff/cache=0, available=450. The administrator notices the system is actively swapping. Which immediate action is the most appropriate to restore service while a permanent fix is planned?

Increase the size of the swap partition to provide more headroom

Identify the top memory-consuming process and consider restarting it or reducing its memory footprint

Adjust `vm.swappiness` to 0 to prevent the kernel from swapping

Restart the web server service to release its cached memory

Users report that a web application is slow. `ifstat` shows the network interface is receiving 95 Mbps on a 100 Mbps link. `ss -s` shows 10,000 established connections. `mpstat -P ALL 1` shows all cores at 50% utilization. Which component is most likely the bottleneck?

The memory, because 10,000 connections consume significant RAM

The CPU, because 50% utilization on all cores is too high for a web server

The network interface, because it is receiving at 95% of its capacity

The disk, because web applications require disk I/O for logging
