Question 1

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

Accepted Answer

Multimode fiber optic cable

Answer

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

Question 2

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

Accepted Answer

OFDMA

Answer

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

Question 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?

Accepted Answer

10.0.5.0/24

Answer

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.

Question 4

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

Accepted Answer

Spanning Tree Protocol

Answer

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

Question 5

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