Establishing a theory
Implementing the solution
Identifying the problem clearly defines what needs to be resolved and prevents wasted effort. A precise problem statement guides all subsequent diagnostic steps.
Which tool allows you to safely verify the presence of AC voltage without contact?
Digital multimeter
Non-contact voltage tester
Oscilloscope
Cable continuity tester
A non-contact voltage tester detects the electric field around live conductors without touching them. This tool reduces risk when checking for powered circuits.
In a US-style electrical schematic, which symbol represents a resistor?
Straight line with arrow

Rectangle
Circle with an R
In American schematics, a resistor is drawn as a series of zigzag lines. Recognizing this symbol is key to analyzing circuit diagrams.
Which waveform on an oscilloscope typically indicates a digital clock signal?
Sine wave
Square wave
Triangular wave
Sawtooth wave
Digital clock signals alternate between two levels at a steady rate, producing a square wave. Identifying this waveform confirms clock integrity.
Which tool is best for surveying available Wi-Fi networks and signal strength on site?
Ping utility
Wi-Fi analyzer
Netstat
iPerf
A Wi-Fi analyzer scans channels, lists SSIDs, and measures signal strength to help optimize wireless coverage. It is essential for wireless site surveys.
What is the primary purpose of a lockout-tagout procedure before maintenance?
Preventing equipment energizing
Documenting spare parts
Improving system performance
Reducing electromagnetic interference
Lockout-tagout ensures that power sources are isolated and cannot be re-energized while maintenance is in progress. This prevents accidental startup and protects technicians.
Which setting on a digital multimeter is used to measure electrical current?
Continuity (diode)
Resistance (Ω)
Voltage (V)
Current (A)
The ampere (A) setting on a multimeter is designed to measure current flow through a circuit. Using the correct setting prevents meter damage and ensures accurate readings.
Which device is used to measure optical power loss on a fiber optic link?
Optical time-domain reflectometer (OTDR)
Optical power meter
Time-domain reflectometer (TDR)
Spectrum analyzer
An optical power meter measures the power level of a light source received at the far end of a fiber link. Comparing this to the transmitter's output gives the attenuation.
Which communication technique involves fully concentrating, understanding, and responding to a client's message?
Distraction listening
Active listening
Selective listening
Passive listening
Active listening requires focusing entirely on the speaker, clarifying points, and providing feedback. This builds rapport and ensures accurate understanding of client needs.
Which protocol uses UDP port 161 for network device management?
HTTP
SNMP
FTP
SMTP
SNMP (Simple Network Management Protocol) operates over UDP port 161 to poll and manage network devices. It is widely used for monitoring performance and status.
A TDR trace shows a reflection at 200 nanoseconds on a cable with a velocity factor of 0.7. What is the approximate distance to the fault?
21 meters
28 meters
35 meters
14 meters
Distance is calculated as (velocity à - time)/2. With v = 0.7c (≈2.1à - 10^8 m/s) and t = 200 ns, distance ≈ (2.1à - 10^8 à - 200à - 10^-9)/2 ≈ 21 meters.
A fiber link specifies attenuation ≤ 3.5 dB/km. You measure 4.0 dB over 1 km. What is your next corrective action?
Reduce transmitter power
Accept the link as is
Replace the entire cable
Clean and inspect connectors
Dirty or damaged connectors often cause excess loss. Cleaning and inspecting connectors is the first corrective step before considering cable replacement.
A system performance graph shows CPU usage at 95%, memory at 40%, disk I/O at 30%, and network throughput at 25%. What is the primary performance bottleneck?
Memory
Network
Disk I/O
CPU
The CPU is at 95% utilization, significantly higher than other resources. This indicates the processor is the primary constraint on system performance.
A remote site's LTE signal strength measures - 95 dBm, resulting in frequent disconnects. What is the most effective improvement?
Reduce data bandwidth
Install an external directional antenna
Move the router away from the window
Change to single SIM operation
Signal levels below - 90 dBm are considered poor. Installing an external directional antenna can significantly boost reception and improve connection stability.
When diagnosing packet loss over multiple network hops, which tool helps pinpoint the problematic hop?
iperf
netstat
nslookup
traceroute
Traceroute maps the path packets take and measures round-trip times at each hop. It helps identify the specific segment where packet loss or latency spikes occur.
