Sample Practice Questions for Network Infrastructure, Cabling & Hardware

  1. Question 1Ref: CompTIA Network+ N10-009 — Infrastructure: Switching Technologies, 20%

    A network administrator configures a switch port so that devices on VLAN 10 and VLAN 20 can communicate through a single router interface. What is this configuration called?

    Show Answer & Explanation

    Correct Answer
    B. Router on a stick

    The keyed answer is "Router on a stick". Router on a stick uses subinterfaces on a single router port to route between VLANs. The trunk link carries tagged frames, and each subinterface handles one VLAN's traffic.

  2. Question 2Ref: CompTIA Network+ N10-009 — Infrastructure: Switching Technologies, 20%

    A company needs to ensure that if one uplink fails, the remaining links still carry traffic between two switches. Which technology should the administrator implement?

    Show Answer & Explanation

    Correct Answer
    D. Link Aggregation Control Protocol

    The keyed answer is "Link Aggregation Control Protocol". LACP bundles multiple physical links into a logical channel, providing increased bandwidth and failover. If one link fails, traffic redistributes across remaining members.

  3. Question 3Ref: CompTIA Network+ N10-009 — Infrastructure: Wireless Devices, 20%

    A network administrator needs to configure a wireless access point for a high-density conference hall. Which band should be primarily used to minimize interference from Bluetooth devices?

    Show Answer & Explanation

    Correct Answer
    A. 5 GHz

    The keyed answer is "5 GHz". The 5 GHz band offers more channels and is less congested than 2.4 GHz, which shares spectrum with Bluetooth, microwaves, and other devices. 60 GHz is mmWave with very limited range.
