Question 1

A carrier needs to extend fiber reach beyond 80 km without regeneration. Which technology is most appropriate?

Accepted Answer

DWDM with optical amplifiers

Answer

DWDM combined with EDFA optical amplifiers allows signal transmission well beyond 80 km without electronic regeneration.

Question 2

Which network topology provides the highest resiliency for a metropolitan core network?

Accepted Answer

Full mesh topology

Answer

Full mesh topology gives every node a direct path to every other node, eliminating single points of failure.

Question 3

A telecom operator is deploying small cells in a dense urban area. What backhaul technology is most commonly used when fiber is unavailable?

Accepted Answer

mmWave wireless backhaul

Answer

Millimeter-wave (mmWave) wireless backhaul provides the high capacity and low latency needed for dense urban small cell deployments when fiber isn't available.

Question 4

In a carrier Ethernet network, which protocol is used to prevent loops while maintaining redundant paths?

Accepted Answer

MSTP (Multiple Spanning Tree Protocol)

Answer

MSTP prevents bridging loops in Ethernet networks while allowing multiple spanning tree instances for load balancing across VLANs.

Question 5

What is the primary function of a Network Operations Center (NOC) in a telecommunications company?

Accepted Answer

24/7 monitoring, fault management, and network restoration

Answer

A NOC provides continuous monitoring of network performance, rapid fault detection, and coordinates restoration activities to minimize outage impact.
