Networking - Interview Questions and Answers


  1. Which layer links the network support layers and user support layers?
    The Transport layer links the network support layers and user support layers.
  2. What are the concerns of the Physical Layer?
    Physical layer coordinates the functions required to transmit a bit stream over a physical medium.
    a. Physical characteristics of interfaces and media
    b. Representation of bits
    c. Data rate
    d. Synchronization of bits
    e. Line configuration
    f. Physical topology
    g. Transmission mode
  3. What are the responsibilities of Data Link Layer?
    The Data Link Layer transforms the physical layer, a raw transmission facility, to a reliable link and is responsible for node-node delivery.
    a. Framing
    b. Physical Addressing
    c. Flow Control
    d. Error Control
    e. Access Control
  4. What are the responsibilities of Network Layer?
    The Network Layer is responsible for the source-to-destination delivery of packet possibly across multiple networks (links).
    a. Logical Addressing
    b. Routing
  5. What are the responsibilities of Transport Layer?
    The Transport Layer is responsible for source-to-destination delivery of the entire message.
    a. Service-point Addressing
    b. Segmentation and reassembly
    c. Connection Control
    d. Flow Control
    e. Error Control
  6. What are the responsibilities of Session Layer?
    The Session layer is the network dialog Controller. It establishes, maintains and synchronizes the interaction between the communicating systems.
    a. Dialog control
    b. Synchronization
