Read the first 7 Technologies & Infrastructure flashcards as text

  1. Which multiplexing technique divides a fiber optic channel into multiple wavelengths to increase capacity?

    Answer: Dense Wavelength Division Multiplexing (DWDM)

    DWDM combines multiple optical carrier signals on a single fiber by using different wavelengths, dramatically increasing bandwidth capacity.

  2. In a Software-Defined Networking (SDN) architecture, which plane is centralized and manages routing decisions?

    Answer: Control plane

    In SDN, the control plane is decoupled from hardware and centralized in a controller, which makes all routing and forwarding decisions.

  3. What is the primary advantage of using a Metro Ethernet network for enterprise connectivity?

    Answer: It extends familiar Ethernet protocols over a wide metro area at high bandwidth

    Metro Ethernet allows enterprises to connect sites across a city using standard Ethernet interfaces, simplifying operations and offering scalable bandwidth.

  4. Which technology standard defines the air interface for 5G New Radio (NR)?

    Answer: 3GPP Release 15

    3GPP Release 15 is the first formal 5G NR standard, defining the radio access network specifications for sub-6 GHz and mmWave bands.

  5. A telco plans to deploy Massive MIMO antennas. What is the primary benefit?

    Answer: Increases spectral efficiency by serving multiple users simultaneously with beamforming

    Massive MIMO uses large antenna arrays and beamforming to spatially multiplex many users on the same time-frequency resource, boosting spectral efficiency.

  6. What does the term 'network slicing' refer to in a 5G context?

    Answer: Creating multiple virtual networks on a shared physical infrastructure tailored to specific use cases

    Network slicing uses virtualization to create isolated logical networks on shared infrastructure, each with customized QoS, security, and bandwidth for different services.

  7. Which protocol is used by service providers to distribute MPLS labels along a Label Switched Path (LSP)?

    Answer: LDP (Label Distribution Protocol)

    LDP is the standard protocol used to establish LSPs by distributing label-to-FEC bindings between MPLS-enabled routers.
