CompTIA Network+ Practice Test for Subdomain 3.1 #01

Question 1

A network engineer reviewing onboarding documentation at a mid-sized logistics company needs to identify which diagram type shows the actual physical placement of devices, cable runs, and rack locations in the building. The engineer also needs a separate diagram depicting how data flows between devices, including IP addresses, VLANs, and routing relationships. Which statement correctly differentiates these two documentation types?

A. A logical diagram shows physical device placement; a physical diagram shows IP addressing and routing relationships. B. A physical diagram shows the actual layout of hardware and cabling; a logical diagram shows network addressing, VLANs, and traffic flows. C. Both diagram types convey the same information but are formatted for different audiences. D. A physical diagram is used only for wireless networks; a logical diagram is used only for wired networks.

Question 2

A systems administrator at a growing e-commerce company is struggling to track IP address assignments across dozens of subnets, resulting in duplicate addresses and configuration errors. The administrator needs a centralized solution to allocate, track, and audit IP address usage across the entire enterprise network. Which tool or practice is specifically designed to address this need?

A. A DHCP reservation table stored on the primary DHCP server B. IP address management (IPAM) C. A network monitoring system (NMS) with SNMP polling D. A DNS zone file containing all static A records

Question 3

A network operations center (NOC) manager at a managed service provider is reviewing contracts with enterprise clients. One client's contract stipulates that the NOC must restore network connectivity within four hours of a reported outage and maintain 99.9% availability per calendar month. Which type of formal document defines these performance expectations and associated remedies?

A. A memorandum of understanding (MOU) B. A service-level agreement (SLA) C. A change management policy D. A standard operating procedure (SOP)

Question 4

A network team at a university is reviewing infrastructure lifecycle documentation. The team discovers that a core router model reached end-of-life (EOL) two years ago, while a critical firewall reached end-of-support (EOS) last quarter. Which statement most accurately describes the operational difference between these two lifecycle designations?

A. EOL means the vendor no longer sells the product; EOS means the vendor will no longer provide patches, updates, or technical support. B. EOL means the device can no longer be powered on; EOS means the vendor has stopped manufacturing replacement parts. C. EOL and EOS are interchangeable terms that both mean the vendor will no longer sell or support the device. D. EOL means the vendor has issued a direct replacement product; EOS means the device's warranty period has expired.

Question 5

A network engineer at a financial institution plans to upgrade the firmware on a production core switch during the upcoming weekend maintenance window. Company policy requires the engineer to submit a formal request that documents the scope, rollback plan, and expected impact before any work begins. Which organizational process governs this requirement?

A. Configuration management B. Incident management C. Change management D. Asset lifecycle management

Question 6

A network administrator at a retail chain is reviewing the company's configuration management practices. Three saved copies of the core router configuration are found: one reflecting the device's current running state, one serving as the approved standard for new deployments, and one kept as a recovery copy in case of failure. Which set of terms correctly maps to these three configuration types?

A. Running, template, and recovery configurations B. Production, baseline/golden, and backup configurations C. Active, standard, and archive configurations D. Live, default, and snapshot configurations

Question 7

A compliance auditor at a healthcare organization requests documentation that lists all network-connected hardware devices, including model numbers, purchase dates, and current warranty status. The network team provides a report generated from their centralized management system. Which component of network documentation does this report represent?

A. A network topology diagram B. An asset inventory C. An IP address management (IPAM) database D. A cable map and diagram

Question 8

A facilities manager at a corporate headquarters reports that employees on the east wing of the third floor are experiencing poor Wi-Fi connectivity despite access points being installed throughout the floor. A network technician is tasked with identifying dead zones and signal overlap areas before reconfiguring the wireless deployment. Which tool or technique should the technician use to visually map signal coverage and identify problem areas?

A. A network topology diagram B. A wireless survey and heat map C. A cable map and diagram D. An SNMP trap log from the wireless controller

Question 9

A network technician is preparing to install new equipment in a data center cage. Before beginning the installation, the technician needs to reference a document showing the exact vertical positioning of each device in the rack enclosure, including the U-space occupied by patch panels, switches, servers, and cable managers. Which type of documentation does the technician need?

A. A logical network diagram B. A rack diagram C. A physical floor plan D. An asset inventory spreadsheet

Question 10

A network manager at a government agency is retiring a batch of access switches that have reached end-of-support. Before the devices are removed from the network, the manager must ensure that sensitive configuration data -- including usernames, passwords, SNMP community strings, and ACL rules -- cannot be recovered from the devices after disposal. Which step in the asset lifecycle process addresses this requirement?

A. End-of-life (EOL) notification B. Decommissioning C. Backup configuration archiving D. Warranty disposition
