Cisco Supporting Cisco Devices for Field Technicians Exam Practice Test
The Cisco Supporting Cisco Devices for Field Technicians Exam practice page centers on hands-on support work across networked devices and user equipment. Practice topics include IPv4 subnet calculations, switch-change records, desktop hardware safety, fiber-optic measurement, wireless roaming, and basic Windows network checks. These scenarios emphasize recognizing the right diagnostic information, tool, or precaution for a field task.
Exam overview
About the Cisco Supporting Cisco Devices for Field Technicians Exam
Field support requires connecting symptoms to evidence before changing hardware or configuration. The question bank includes tasks such as checking a DHCP-assigned address and default gateway, identifying the process associated with a listening TCP port, and comparing CPU readings over time to distinguish a persistent issue from a brief spike. Hardware scenarios call for electrostatic-discharge precautions, checking hot-swap support before removing a power supply, and confirming module compatibility against the device model. Other items exercise optical power measurement at a fiber receiver, wireless roaming investigation, subnet capacity, and clear change documentation. Together, these examples provide practice in gathering relevant details, selecting appropriate tools or records, and avoiding unsupported replacement or configuration decisions during device support.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
A technician is reviewing a subnet with the IPv4 prefix 192.0.2.64/27. How many total IPv4 addresses are in the subnet?
Show answer
Correct answer: BA /27 prefix leaves 32 − 27 = 5 host bits. Five bits provide 2^5, or 32, total addresses in the subnet. This count includes the network and broadcast addresses in conventional IPv4 subnetting.
A technician is documenting a change to a managed switch. Which record best helps another technician understand what was changed and when?
Show answer
Correct answer: AA clear change log records the affected device, timing, actions, and outcome, supporting troubleshooting and accountability. Unrelated credentials or unlabeled photos do not provide an adequate change history.
A technician is replacing a failed network adapter in a desktop. Which precaution should be taken before opening the computer case?
Show answer
Correct answer: AShutting down and disconnecting power helps prevent electrical hazards and accidental component damage during service. Network settings can be checked after the replacement is installed.
A technician is checking a fiber link and needs to measure the optical signal level arriving at the receiver end. Which tool is most appropriate?
Show answer
Correct answer: AAn optical power meter measures optical power at a fiber link, helping determine whether the received signal level is within an acceptable range. A toner, multimeter, or electrical loopback plug does not measure optical power.
A technician must replace a hot-swappable power supply in a supported network device. What should be verified before removing the failed module?
Show answer
Correct answer: AHot-swap capability depends on the specific device and module, so the technician should verify support and follow the applicable service procedure before removal. Assuming all power supplies are hot-swappable can cause an outage or equipment damage.
A user reports that a laptop connects to a wireless network but repeatedly drops its connection while moving between rooms. Which factor is most relevant to investigate?
Show answer
Correct answer: AMovement-related wireless drops can result from weak coverage, interference, or roaming behavior. Reviewing signal conditions and the wireless environment is relevant; the other choices are unrelated.
A field technician needs to verify which IPv4 address and default gateway a Windows laptop received from DHCP. Which command displays this information?
Show answer
Correct answer: AOn Windows, ipconfig displays network adapter settings, including the IPv4 address and default gateway. The other commands test connectivity, trace a route, or query DNS.
How to use this practice test
Access is free. The bank contains 50 published questions, with up to 20 random questions in a session. Submit a session to see results, then use missed items to identify specific gaps—for example, subnet arithmetic, Windows network commands, fiber test tools, or hardware replacement checks.
Preparation tips
- Work IPv4 prefix questions by identifying host bits and calculating total addresses; distinguish total addresses from usable host addresses when a prompt asks for one or the other.
- Practice checking Windows DHCP details with ipconfig and interpreting the assigned address, subnet mask, and default gateway as a set.
- Match fiber troubleshooting goals to tools: use an optical power meter to measure received signal level, and note the measurement point and units.
- Before replacing hardware, check the device documentation for hot-swap support and verify the replacement part against the exact model and compatibility information.
- For intermittent wireless drops, record where and when they occur, then investigate coverage and roaming conditions rather than assuming the laptop has lost all wireless connectivity.
