PK0-005 Practice Question: Refer to the exhibit
Exhibit
Refer to the exhibit. Command: netstat -an | grep :80 tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN tcp 0 0 192.168.1.10:80 192.168.1.5:54321 ESTABLISHED tcp 0 0 192.168.1.10:80 192.168.1.6:54322 TIME_WAIT
Refer to the exhibit. A project manager is monitoring server performance for a web application deployment. Based on the exhibit, what is the status of the web server?
⚠ Common exam trap
CompTIA often tests the misconception that a 'LISTENING' port alone is insufficient to confirm the server is handling connections, but the presence of 'ESTABLISHED' sessions in the exhibit directly proves active traffic handling, making D correct.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The server is running and handling connections
The exhibit shows the web server is in a 'LISTENING' state on port 80, with established connections (ESTABLISHED) to client IPs. This indicates the server process is running, the TCP handshake completed successfully, and it is actively handling HTTP requests. Option D is correct because a listening socket with established sessions confirms operational status.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The server has a firewall blocking connections
Why it's wrong here
Firewall blocking would manifest as dropped or timed-out connections to specific ports, whereas the exhibit shows the server reachable and returning responses. It is tempting because blocked traffic mimics outage symptoms, but firewall diagnosis is correct only when connectivity tests fail while the service itself remains healthy.
- ✗
The server is overloaded
Why it's wrong here
Overload would require sustained CPU, memory or queue saturation with degraded response times. The exhibit shows utilisation within normal thresholds, so the server is healthy; overload is tempting whenever utilisation appears elevated, but the metrics do not demonstrate resource exhaustion.
- ✗
The server is not running
Why it's wrong here
The exhibit shows the web server responding to monitoring checks, so it is running; a stopped service would produce connection refusals or absent metrics rather than the observed values. Not running is tempting when availability looks degraded, but that conclusion requires the service itself to be down, not merely performing poorly.
- ✓
The server is running and handling connections
Why this is correct
The exhibit shows active TCP connections and steady CPU and memory use, confirming the web server is running and serving requests. This satisfies the stem's requirement to determine live operational status, since established connections prove the service is accepting and handling client traffic rather than being stopped or idle.
