Network Operations — Network+ practice questions

Domain 3 of the CompTIA Network+ (N10-009) exam. 170 questions on this domain in the full bank — here are four free samples with answers and explanations.

Question 1 · Difficulty 2/5

Which type of network documentation shows the physical location of devices within a data center enclosure, including their rack unit (U) position and power draw? (Select the best answer.)
  1. Logical network diagram
  2. Cable map
  3. Rack diagram
  4. Wireless heat map
Show answer & explanation

Correct answer: C

Rack diagram
A rack diagram (sometimes called an elevation diagram) documents the physical layout of equipment within a rack enclosure, including each device's position in rack units (U), power requirements, and physical dimensions. A logical network diagram depicts IP addressing, routing, and Layer 3 relationships, not physical placement. A cable map records individual cable runs, patch panel ports, and termination points. A wireless heat map illustrates signal strength distribution across a physical space, not rack-level equipment layout.

Question 2 · Difficulty 3/5

A company recently completed a wireless deployment and wants to confirm that no areas of the office floor have received insufficient Wi-Fi signal coverage before users move in. Which documentation artifact should the wireless engineer produce to present these findings? (Select the best answer.)
  1. Layer 1 physical diagram
  2. Wireless heat map
  3. Cable map
  4. Logical network diagram
Show answer & explanation

Correct answer: B

Wireless heat map
A wireless heat map is a visual overlay on a floor plan that represents received signal strength indicator (RSSI) values across the coverage area, allowing engineers to identify weak-signal zones before deployment is finalized. A Layer 1 physical diagram shows device interconnections at the physical layer (ports, cables, media) but does not represent RF signal distribution. A cable map documents structured cabling runs, not RF characteristics. A logical network diagram shows IP addressing and routing topology, which is unrelated to RF coverage validation.

Question 3 · Difficulty 2/5

Which type of network documentation records details such as device model numbers, installed software versions, license expiration dates, and warranty end dates for all network equipment in an organization? (Select the best answer.)
  1. IP address management (IPAM) database
  2. Asset inventory
  3. Logical network diagram
  4. Service-level agreement (SLA)
Show answer & explanation

Correct answer: B

Asset inventory
An asset inventory is the documentation artifact that tracks hardware specifications, installed software versions, license keys and expiration dates, warranty status, and support contract details for every managed device. An IPAM database tracks IP address allocations and subnet assignments, not hardware lifecycle data. A logical network diagram shows Layer 2/3 topology relationships such as IP addressing and routing protocols, not individual device asset records. An SLA is a contractual document defining uptime guarantees and support response times, not a record of device attributes.

Question 4 · Difficulty 3/5

A network operations center manager is in a dispute with an ISP regarding repeated outages that exceeded the agreed-upon monthly downtime threshold. The manager wants to determine what remedies, such as service credits or escalation procedures, the organization is entitled to. Which document should the manager consult first? (Select the best answer.)
  1. Asset inventory
  2. Network change log
  3. Service-level agreement (SLA)
  4. IPAM database
Show answer & explanation

Correct answer: C

Service-level agreement (SLA)
A service-level agreement (SLA) is the contractual document between a customer and a service provider that defines uptime guarantees, performance metrics, breach thresholds, and remedies such as service credits or escalation paths. The asset inventory records hardware and software details unrelated to ISP contractual obligations. A network change log records configuration changes made internally and does not govern ISP remedies. An IPAM database manages IP address allocation and is unrelated to contractual service terms.
