CompTIA Network+ Practice Test for Subdomain 3.2 #03

Welcome to today’s CompTIA Network+ practice test!

This practice test uses our new UI!

Today’s practice test is based on Subdomain 3.2 (Given a scenario, use network monitoring technologies) from the CompTIA Network+ N10-009 objectives.

This beginner-level practice test is inspired by the CompTIA Network+ (N10-009) exam and is designed to help you reinforce key networking concepts on a daily basis.

These questions are not official exam questions, nor are they brain dumps, but they reflect topics and scenarios relevant to the Network+ certification. Use them to test your knowledge, identify areas for improvement, and build daily cybersecurity habits.

CompTIA Network+ Practice Test of the Day 260701

10 questions • Single best answer

Question 1

A network operations manager at an e-commerce company needs to know immediately when a critical router goes offline without waiting for the next scheduled poll cycle. The monitoring system must detect failures as they occur rather than at fixed intervals. Which monitoring category addresses this requirement?

A. Performance monitoring B. Configuration monitoring C. Traffic analysis D. Availability monitoring

Question 2

A systems administrator at a healthcare network notices that interface utilization on a core switch has been steadily climbing over the past week. The team needs historical data on bandwidth consumption, error rates, and CPU load to identify a developing bottleneck. Which monitoring category provides this data?

A. Availability monitoring B. Performance monitoring C. Log aggregation D. Ad hoc discovery

Question 3

A security team at a government agency wants automated alerts any time a network device's running configuration changes from its approved baseline. Any unauthorized modification to ACLs or routing protocol settings must trigger an immediate notification. Which monitoring type fulfills this requirement?

A. Configuration monitoring B. Traffic analysis C. Availability monitoring D. Flow data collection

Question 4

A network engineer at a managed services provider uses a monitoring tool to proactively examine patterns in network traffic to identify unusual protocol usage and bandwidth-heavy applications across client sites. No full packet payloads are captured. Which monitoring function is being performed?

A. Configuration monitoring B. Availability monitoring C. Traffic analysis D. Baseline anomaly detection

Question 5

A NOC engineer at a cloud provider runs an on-demand scan of all connected endpoints in a specific subnet after a security incident is reported. The scan is triggered manually rather than on a fixed schedule. Which network discovery mode is being used?

A. Scheduled discovery B. Ad hoc discovery C. Flow data sweep D. Passive monitoring

Question 6

A network administrator needs to query a managed switch to retrieve current interface statistics using SNMP. The management station sends a request asking for a specific variable's value, and the device responds with the data. Which SNMP operation describes this exchange?

A. SNMP trap B. MIB walk C. Community string rotation D. SNMP GET

Question 7

A security engineer is comparing SNMP versions for a new deployment. One version uses a cleartext shared credential with no encryption, while another offers user-based authentication with AES encryption for management traffic. The engineer must choose the version that satisfies a strict confidentiality requirement. Which version meets this need?

A. SNMPv1 B. SNMPv2c C. SNMPv3 D. SNMP with TLS wrapping

Question 8

A network monitoring platform is configured to pull device metrics and receive event data through a vendor's published interface rather than through traditional polling protocols. Scripts query the platform and receive structured responses in JSON format. Which integration method is being used?

A. API integration B. SNMP polling C. Syslog forwarding D. Port mirroring

Question 9

A security analyst at an insurance company needs to capture every byte of traffic between two specific servers to reproduce a reported application error. The analyst requires full packet payloads, not just traffic summaries. Which monitoring method should be used?

A. Flow data export B. SNMP polling C. Syslog collection D. Packet capture

Question 10

A monitoring team at a financial institution establishes normal traffic patterns and device performance levels over a 30-day period. The system is then configured to alert automatically when current measurements deviate significantly from those established norms. Which monitoring feature enables this detection?

A. Configuration monitoring B. Baseline metrics with anomaly alerting C. Ad hoc discovery D. Syslog severity filtering
