    What technology allows 24 DS0 channels to be combined into a single DS1 or T1 channel?

    • Wide Area Networking

    • Signaling Over Time

    • Time-Division Multiplexing

    • Channel-Aggregation Sequencing

    Correct Answer
    A. Time-Division Multiplexing
    Explanation
    Time-Division Multiplexing is the technology that allows 24 DS0 channels to be combined into a single DS1 or T1 channel. This technique divides the available bandwidth into multiple time slots, with each slot being assigned to a different channel. By rapidly switching between these channels, data from multiple sources can be transmitted over a single communication line, maximizing the utilization of the available bandwidth.

    In which type of switching is the entire packet received and checked before sending it?

    • Cut-Through

    • Store-And-Forward

    • FragmentFree

    • Low Latency

    Correct Answer
    A. Store-And-Forward
    Explanation
    Store-And-Forward switching is the type of switching where the entire packet is received and checked for errors before it is forwarded to the destination. In this method, the switch buffers the entire packet and performs a CRC (Cyclic Redundancy Check) to verify the integrity of the packet. If the packet is error-free, it is then forwarded to the destination. This method ensures that only error-free packets are transmitted, reducing the chances of data corruption or loss.

    What is another term for "physical address" on a TCP/IP network?

    • IP Address

    • MAC Address

    • Network Jack

    • Home Address

    Correct Answer
    A. MAC Address
    Explanation
    A physical address on a TCP/IP network is commonly referred to as a MAC address. MAC stands for Media Access Control, and it is a unique identifier assigned to network interfaces, such as network cards or Ethernet ports, by the manufacturer. The MAC address is used to identify and communicate with devices on a local network. Unlike an IP address, which can change, the MAC address is permanent and cannot be easily altered.

    What standard developed by Novell and Apple is similar to the NDIS specification?

    • EtherTalk

    • Open Data-link Interface (ODI)

    • IPX/SPX

    • AppleTalk

    Correct Answer
    A. Open Data-link Interface (ODI)
    Explanation
    Open Data-link Interface (ODI) is the correct answer because it was a standard developed by Novell and Apple. ODI was designed to provide a common interface for network drivers, similar to the NDIS (Network Driver Interface Specification) developed by Microsoft. It allowed different network protocols, such as IPX/SPX and AppleTalk, to be supported by the same network interface card. Therefore, ODI is similar to the NDIS specification in terms of providing a standardized interface for network drivers.

    What do switches employing the Spanning-Tree Protocol use to communicate?

    • UDPs

    • BPDUs

    • Switch Cells

    • Hello Protocol

    Correct Answer
    A. BPDUs
    Explanation
    Switches employing the Spanning-Tree Protocol use BPDUs (Bridge Protocol Data Units) to communicate. BPDUs are messages that switches send to each other to exchange information about the network topology and to determine the best path for forwarding network traffic. By exchanging BPDUs, switches can detect and prevent loops in the network, ensuring a loop-free and redundant network infrastructure.

    • FDDI

    • SNA

    Correct Answer
    A. FDDI
    Explanation
    FDDI (Fiber Distributed Data Interface) is the correct answer because it is a networking technology that uses dual counter-rotating token-passing ring networks. FDDI is a high-speed LAN technology that uses optical fiber to transmit data. It employs a dual-ring architecture where data is transmitted in one direction on one ring and in the opposite direction on the other ring. This dual counter-rotating ring design provides redundancy and fault tolerance, ensuring reliable data transmission.
