    Explanation
    During normal operating conditions with commercial AC power available, facility batteries act as a DC filter for the commercial AC power. This means that they remove any unwanted noise or fluctuations from the AC power supply, ensuring a clean and stable DC power output. This filtered DC power is then used to power the system and run the switch. The other options are incorrect as they do not accurately describe the function of facility batteries during normal operating conditions.

    (034) When a multimeter has three input terminal jacks, which jack is always used?

    • Common.

    • Voltage.

    • Amperage.

    • Frequency.

    Correct Answer
    A. Common.
    Explanation
    When a multimeter has three input terminal jacks, the jack that is always used is the "Common" jack. The common jack is used as the reference point for voltage and amperage measurements. It is typically connected to the ground or the negative terminal of the circuit under test. The other two jacks, voltage and amperage, are used depending on the type of measurement being taken. The voltage jack is used for measuring voltage, while the amperage jack is used for measuring current. The frequency jack is not always present on a multimeter and is used specifically for measuring frequency.

    (035) The purpose of the miniature ON/OFF switches on a breakout box is to

    • Measure the individual interface signals

    • Change the voltage of individual interface signals.

    • Allow the cross-patching of the individual interface conductors.

    • Allow the interruption of the individual interface conductors for isolated testing.

    Correct Answer
    A. Allow the interruption of the individual interface conductors for isolated testing.
    Explanation
    The purpose of the miniature ON/OFF switches on a breakout box is to allow the interruption of the individual interface conductors for isolated testing. This means that the switches can be used to temporarily disconnect specific interface signals, allowing them to be tested or isolated without affecting the rest of the system. This can be useful for troubleshooting or diagnosing issues in complex systems with multiple interface signals.

    (037) Sampled data points are stored in the memory of a digital storage oscilloscope as

    • Sequential records.

    • Waveform points.

    • Record lengths.

    • Record points.

    Correct Answer
    A. Waveform points.
    Explanation
    In a digital storage oscilloscope, sampled data points are stored in the memory as waveform points. These points represent the amplitude of the signal at specific time intervals. By storing the waveform points, the oscilloscope can accurately reconstruct and display the waveform on the screen for analysis and measurement purposes. The waveform points allow for a detailed representation of the signal, capturing its shape and characteristics.

    (038) What type of error is the result of two successive logic one pulses of the same polarity that violates alternate mark inversion coding rules?

    • Cyclic redundancy check

    • Bipolar violation.

    • Bit slip.

    • Frame.

    Correct Answer
    A. Bipolar violation.
    Explanation
    A bipolar violation is the type of error that occurs when two successive logic one pulses of the same polarity violate alternate mark inversion coding rules. Alternate mark inversion is a coding scheme used in telecommunications to ensure that the signal remains balanced and that a long string of ones or zeros does not cause timing or synchronization issues. A bipolar violation indicates a violation of this coding scheme and can lead to errors in data transmission.

    (040) What active test on a protocol analyzer is selected to see the path that the packets are traveling and the time it takes the packets to compete the trip?

    • Trace route.

    • Route generator.

    • Traffic generator.

    • Packet internetwork groper (PING).

    Correct Answer
    A. Trace route.
    Explanation
    The correct answer is Trace route. Trace route is an active test on a protocol analyzer that allows users to see the path that packets are traveling and the time it takes for the packets to complete the trip. It helps in identifying the routers or hops that the packets go through, providing valuable information for troubleshooting network connectivity issues.

    (017) What is the grounding resistance goal for military communications electronics (C-E) facilities?

    • 100 ohms or less.

    • 50 ohms or less.

    • 20 ohms or less.

    • 10 ohms or less.

    Correct Answer
    A. 10 ohms or less.
    Explanation
    The grounding resistance goal for military communications electronics (C-E) facilities is 10 ohms or less. This means that the resistance between the ground and the facility should be 10 ohms or lower. This is important because a low grounding resistance helps to ensure that electrical equipment and systems within the facility are properly grounded, which can prevent electrical shocks, reduce the risk of equipment damage from electrical surges, and improve overall safety and performance of the facility.

    (028) Which type of cable does not radiate energy and is not affected by nearby magnetic fields?

    • Unshielded.

    • Shielded.

    • Twisted pair.

    • Multipair.

    Correct Answer
    A. Shielded.
    Explanation
    Shielded cables are designed with a protective layer of shielding material, such as a conductive metal foil or braided wire, which helps to prevent the transmission of electromagnetic interference (EMI) and also reduces the emission of electromagnetic radiation. This shielding effectively blocks out external magnetic fields and prevents them from interfering with the signals transmitted through the cable. As a result, shielded cables are not affected by nearby magnetic fields and do not radiate energy, making them ideal for applications where electromagnetic interference is a concern.

    • Binder.

    Correct Answer
    A. Binder.
    Explanation
    The correct answer is binder. A binder is a type of stationary item used to hold and organize loose papers or documents. The thin plastic colored tape described in the question is commonly found wrapped around the rings of a binder, indicating the color-coding system used to categorize and identify the contents inside.
