Objective 3.5: Given a scenario, use the appropriate network discovery, monitoring, or management tool
Practice questions for Network+ objective 3.5, “Given a scenario, use the appropriate network discovery, monitoring, or management tool.” Every question is original, written to the N10-009 exam objectives, and comes with a full explanation — answer them below to see instant grading.
This objective sits in Domain 3.0: Network Operations, which is about 20% of the exam — so mastering it moves your readiness score meaningfully.
1.A wireless network engineer is investigating complaints of slow Wi-Fi performance in a conference room. They need to identify overlapping channels, signal strength, and interference sources from neighboring networks. Which tool should they use?
2.A network administrator needs to discover all active hosts on the 10.0.0.0/24 subnet and identify which TCP and UDP ports are open on each host. Which tool is designed for this purpose?
3.After a firewall rule change, traffic patterns have changed. A network engineer wants to compare current NetFlow data against a historical baseline to identify anomalies. What approach is being used?
4.A network administrator wants to measure the available bandwidth between two endpoints without purchasing specialized equipment. Which free, cross-platform tool is most commonly used for this purpose?
5.Which tcpdump command captures all traffic on interface eth0 and saves it to a file named capture.pcap for later analysis?
