A network technician is equipping a field kit with diagnostic tools for physical and protocol-level troubleshooting. Match each diagnostic tool to the scenario where it provides the required functionality.
- Optical Time-Domain Reflectometer (OTDR)Determining the distance to a fault and light loss along a single-mode fiber run
- Tone Generator and ProbeLocating an unlabelled copper cable within a bundled rack at a patch panel
- MultimeterChecking DC voltage output from a Power over Ethernet (PoE) injector supply
- Packet AnalyzerInspecting TCP three-way handshake flags and DHCP offer options
Answer
Optical Time-Domain Reflectometer (OTDR) matches determining distance to fault and light loss in single-mode fiber; Tone Generator and Probe matches locating unlabelled copper cable in a patch panel; Multimeter matches checking DC voltage output from a power injector; Packet Analyzer matches inspecting TCP handshake flags and DHCP offer options.
Each diagnostic tool is aligned with its specific physical medium and domain: OTDR analyzes fiber optic reflection, the tone generator and probe locate metallic copper wire paths, the multimeter measures electrical properties like voltage, and the packet analyzer inspects protocol headers and frame contents.
