  1. Which protocol is used to automatically assign IP addresses to devices on a network?

    Answer: DHCP

    DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses and other network configuration parameters to devices.

  2. What is the maximum cable length for a standard Cat6 horizontal run in a structured cabling system?

    Answer: 90 meters

    TIA-568 standards specify a maximum horizontal cable run of 90 meters, leaving 10 meters for patch cords at each end for a total channel length of 100 meters.

  3. In a converged network carrying voice, data, and video, which QoS mechanism prioritizes time-sensitive traffic?

    Answer: 802.1p traffic marking

    802.1p defines class-of-service markings in the Ethernet frame header to prioritize latency-sensitive traffic like voice and video.

  4. What device connects multiple network segments and uses MAC addresses to forward frames only to the correct port?

    Answer: Switch

    A network switch maintains a MAC address table and forwards Ethernet frames only to the port associated with the destination MAC address.

  5. Which fiber optic connector type uses a push-pull latching mechanism and is commonly used in data centers?

    Answer: LC

    The LC (Lucent Connector) uses a push-pull latch and its small form factor makes it ideal for high-density data center environments.

  6. A technician needs to verify end-to-end connectivity on a newly installed Cat6 cable. Which test should be performed first?

    Answer: Wiremap test

    A wiremap test verifies that each conductor is connected to the correct pin at both ends, confirming proper termination before other tests.

  7. What is the purpose of a demarcation point (demarc) in a telecommunications installation?

    Answer: It separates the service provider's network from the customer's network

    The demarcation point establishes the boundary of responsibility between the telecommunications service provider and the customer's premises wiring.
