A company deploys two firewalls in a cluster. The primary firewall handles all traffic while the second unit stays idle, only taking over if the primary fails. During normal operation, the secondary firewall processes no production traffic. Which redundancy configuration does this describe?
A network administrator is preparing next year's hardware refresh budget. Management wants a report identifying which switches and routers will no longer receive vendor firmware updates or hardware replacement support so they can be prioritized for replacement. Which documentation resource is the BEST source for producing this report?
A technician just terminated a new Cat6 patch cable using RJ45 connectors at both ends. When the cable is plugged in, the workstation gets no link light. The technician suspects the termination is wrong. Which tool should be used to confirm that each wire is connected to the correct pin on both ends?
A network technician has resolved an intermittent connectivity issue on a distribution switch by replacing a failing SFP module, and has confirmed that all affected users now have stable connectivity. According to the CompTIA troubleshooting methodology, what should the technician do next?
A Linux server suddenly stops responding to connections from other subnets, though it can still reach devices on its own local network. A technician logs in at the console and needs to quickly confirm the interface's assigned IP address, subnet mask, and whether a default gateway problem exists. Which CLI tool should the technician run FIRST to view the interface's current IP configuration?
A network administrator is documenting the OSI layer where each protocol operates for a compliance audit. She needs to identify which protocol functions at the Application layer (Layer 7) so it can be grouped with the other user-facing services. Which protocol should she list under Layer 7?
A financial services company hires a new intern who will only need to view read-only reports in a single accounting application. During onboarding, the IT administrator is deciding what level of access to grant. Which security principle should guide the administrator to assign only the minimum permissions required for the intern to perform their job?
A new network engineer needs to understand how traffic flows between VLANs, which subnets are assigned to each segment, and how routing is configured across the enterprise. The engineer does not need to know the exact rack or floor location of each device. Which documentation artifact should the engineer consult FIRST?
A network technician is documenting how traffic flows through the corporate network. She observes that one device makes forwarding decisions by examining destination IP addresses and consulting a routing table to select the best path between different subnets. At which OSI layer does this device primarily operate?
A network technician is terminating horizontal cabling runs from wall jacks in a new office suite. The cables enter the telecommunications room and must be organized so that patch cords can later connect each run to a switch port. Which component should the technician terminate these permanent cable runs onto using a punch-down tool?
A network technician needs to identify exactly which switch port a specific wall jack in Room 204 connects to, along with the cable's path through the building's risers and patch panels. Which type of documentation should the technician consult first?
A regional bank needs to connect its main data center to a single remote branch office over a leased line. The link will carry only traffic between these two locations, with no intermediate sites sharing the connection. Which network topology best describes this arrangement?
A network technician is installing new equipment into a standard 42U server rack. The equipment list includes two switches (1U each), a 2U firewall appliance, a 4U UPS, and a patch panel (2U). Following best practices for rack installation, where should the technician mount the UPS?
A network administrator needs to remotely administer a Windows Server that has a graphical management console. Company policy requires the connection to be encrypted and to provide full desktop interaction. Which remote access method should the administrator use?
A small law firm with no dedicated IT staff wants to adopt a hosted email and document collaboration platform. They require that the vendor handle all patching, server maintenance, and application updates, while the firm simply accesses the service through a web browser. Which cloud service model best fits this requirement?
A small office has all 24 workstations cabled back to a single central Ethernet switch. During a network review, a technician documents the physical topology and its resilience characteristics. Which statement most accurately describes this deployment?
A technician needs to identify which cable in a bundle of 40 unlabeled patch cables at the far end of a wiring closet corresponds to a specific wall jack in an office. The cables terminate at a punch-down block, and none are documented. Which tool should the technician use to trace the correct cable?
Before deploying wireless access points in a new three-story office building, a network engineer walks the floors with a laptop and specialized software to measure signal strength, identify sources of interference, and determine optimal AP mounting locations. What is this process called?
