  1. Which wireless band provides the longest range but lowest maximum throughput in 802.11 networks?

    Answer: 2.4 GHz

    2.4 GHz signals travel farther and penetrate obstacles better than higher frequencies, but offer lower maximum throughput due to narrower channel width and more interference.

  2. A technician is installing fiber between two buildings and needs maximum distance. Which fiber type should be selected?

    Answer: OS2 single-mode

    OS2 single-mode fiber supports distances of up to 200 km, far exceeding all multimode varieties and OS1 (which supports up to 10 km).

  3. Which protocol automatically negotiates duplex and speed settings between two connected Ethernet devices?

    Answer: Auto-negotiation

    Auto-negotiation (IEEE 802.3u) allows Ethernet devices to automatically select the highest common speed and duplex mode.

  4. An organization deploys an SD-WAN solution. What is the primary benefit over traditional WAN?

    Answer: Centralized software-based control of multiple WAN links

    SD-WAN uses a centralized software controller to manage and optimize traffic across multiple WAN connections (MPLS, broadband, LTE) based on policy.

  5. Which IPv6 address type is equivalent to IPv4 private addresses and is routable only within the local network?

    Answer: Unique local (fc00::/7)

    Unique local addresses (fc00::/7, commonly fd00::/8) are the IPv6 equivalent of RFC 1918 private addresses — not routable on the public internet.

  6. A switch has three uplink ports to the same distribution switch. Which feature allows all three links to function as one logical high-bandwidth link?

    Answer: LACP/Link Aggregation

    LACP (Link Aggregation Control Protocol, IEEE 802.3ad) bundles multiple physical links into one logical interface to increase bandwidth and provide redundancy.

  7. Which 802.11 amendment introduced MU-MIMO and operates in both 2.4 GHz and 5 GHz bands?

    Answer: 802.11ac (Wi-Fi 5)

    802.11ac (Wi-Fi 5) introduced downlink MU-MIMO and operates exclusively in the 5 GHz band; 802.11ax extended it to uplink and added 2.4 GHz support.
