  1. A network technician needs to connect two buildings that are 400 meters apart. Which medium is most appropriate?

    Answer: Multimode fiber optic cable

    Multimode fiber supports distances up to 550 meters at 10 Gbps, making it ideal for inter-building links under 2 km.

  2. Which 802.11 feature allows multiple access points to serve clients simultaneously on the same channel without interference?

    Answer: OFDMA

    OFDMA (Orthogonal Frequency Division Multiple Access), introduced in 802.11ax (Wi-Fi 6), divides channels into subcarriers to serve multiple clients simultaneously.

  3. A router receives a packet destined for 10.0.5.50. It has routes for 10.0.0.0/8, 10.0.5.0/24, and a default route. Which route is selected?

    Answer: 10.0.5.0/24

    Routers use longest prefix match, so 10.0.5.0/24 (/24 = 24 bits) is more specific than 10.0.0.0/8 (/8 = 8 bits) and is selected.

  4. Which switching feature prevents a port from forwarding frames until it has verified the port is loop-free?

    Answer: Spanning Tree Protocol

    STP (Spanning Tree Protocol) places ports through listening and learning states before transitioning to forwarding, ensuring a loop-free topology.

  5. A company wants to segment IoT devices from corporate workstations on the same physical switch. What is the best solution?

    Answer: Implement VLANs

    VLANs create logical network segments on the same physical switch, isolating IoT devices from corporate traffic without additional hardware.

  6. Which wireless security protocol uses SAE (Simultaneous Authentication of Equals) to replace the PSK handshake?

    Answer: WPA3-Personal

    WPA3-Personal replaces WPA2's PSK with SAE, which provides forward secrecy and protects against offline dictionary attacks.

  7. A technician needs to provide internet access to a remote site over an existing PSTN connection with no other options. Which technology is most appropriate?

    Answer: DSL

    DSL (Digital Subscriber Line) uses existing PSTN copper telephone lines to provide broadband speeds, unlike dial-up which shares the voice channel.
