  1. Which metric best represents the maximum data transfer capacity of a network link?

    Answer: Bandwidth

    Bandwidth defines the maximum theoretical throughput of a network link, typically measured in Mbps or Gbps.

  2. What is the primary advantage of using software-defined networking (SDN)?

    Answer: Separates the control plane from the data plane for centralized management

    SDN decouples the control plane (routing decisions) from the data plane (packet forwarding), enabling centralized, programmable network management.

  3. Which load balancing algorithm routes each new request to the server with the fewest active connections?

    Answer: Least connections

    The least connections algorithm directs traffic to the server currently handling the fewest active sessions, distributing load based on real-time utilization.

  4. What does a network baseline measurement provide in infrastructure management?

    Answer: Normal performance metrics used as a reference for detecting anomalies

    A baseline documents normal network behavior (traffic volume, latency, utilization) so deviations can be quickly identified as potential issues or anomalies.

  5. Which storage network protocol transmits SCSI commands over TCP/IP networks?

    Answer: iSCSI

    iSCSI (Internet Small Computer Systems Interface) encapsulates SCSI commands within TCP/IP packets, enabling block-level storage access over standard IP networks.

  6. In network infrastructure, what is the purpose of a proxy server?

    Answer: To act as an intermediary between clients and external servers for caching and filtering

    A proxy server intercepts client requests to external resources, enabling caching, content filtering, access control, and anonymization.

  7. What is the purpose of Quality of Service (QoS) in network management?

    Answer: To prioritize specific types of traffic to ensure performance for critical applications

    QoS policies assign priority to traffic types (e.g., VoIP, video conferencing) ensuring latency-sensitive applications receive preferential bandwidth and low-delay treatment.
