Read the first 7 Network Systems Integration flashcards as text

  1. A building has multiple telecommunications rooms on different floors. What type of cabling connects these rooms together?

    Answer: Backbone cabling

    Backbone cabling (also called vertical cabling) interconnects telecommunications rooms, equipment rooms, and entrance facilities between floors and buildings.

  2. What is the maximum distance specification for a multimode OM4 fiber running 10 Gigabit Ethernet?

    Answer: 400 meters

    OM4 multimode fiber supports 10 Gigabit Ethernet (10GBASE-SR) at distances up to 400 meters, making it suitable for campus backbone applications.

  3. In network documentation, what does the acronym MDF stand for?

    Answer: Main Distribution Frame

    MDF stands for Main Distribution Frame, which is the primary telecommunications room housing the main cross-connect and typically where outside plant cabling enters the building.

  4. Which switching technology prevents network loops in Ethernet networks with redundant paths?

    Answer: Spanning Tree Protocol (STP)

    Spanning Tree Protocol (STP) and its variants (RSTP, MSTP) detect and block redundant paths to prevent broadcast storms and network loops.

  5. What type of signal loss occurs when light reflects back toward the source at a fiber optic connection or splice?

    Answer: Optical return loss

    Optical return loss (ORL) measures the light reflected back toward the transmitter at connectors, splices, or other discontinuities in a fiber optic link.

  6. A VDV technician is installing coaxial cable for a cable TV distribution system. Which connector type is most commonly used for this application?

    Answer: F-type

    The F-type connector is the standard connector used for residential and commercial cable TV (CATV) and satellite distribution systems due to its low cost and ease of installation.

  7. What is the purpose of a network baseline in system integration projects?

    Answer: To document normal network performance for future comparison

    A network baseline documents normal operating parameters—traffic levels, utilization, response times—providing a reference point to identify deviations and troubleshoot future problems.
