    QUESTION NO: 298 Which of the following logical topologies uses centralized authentication?

    • Peer -to-peer

    • Client/server

    • VPN

    • VLAN

    Correct Answer
    A. Client/server
    Explanation
    The client/server logical topology uses centralized authentication. In a client/server network, there is a central server that manages and controls access to resources. The server authenticates users and grants them access based on their credentials. This centralized authentication ensures that only authorized users can access the network resources, providing a higher level of security and control. In contrast, peer-to-peer, VPN, and VLAN topologies do not necessarily have centralized authentication mechanisms.

    QUESTION NO: 285 Which of the following devices would be used to connect different broadcast domains in order to allow them to communicate with each other?

    • Bridge

    • Layer 2 switch

    • Hub

    • Multilayer switch

    Correct Answer
    A. Multilayer switch
    Explanation
    A multilayer switch would be used to connect different broadcast domains and allow them to communicate with each other. Unlike a bridge or a layer 2 switch, which operate at the data link layer and can only forward packets within the same broadcast domain, a multilayer switch operates at both the data link layer and the network layer. This means that it can not only forward packets within a broadcast domain but also route packets between different broadcast domains, enabling communication between them. A hub, on the other hand, simply broadcasts all incoming packets to all connected devices without any intelligence or segmentation.
