A carrier needs to extend fiber reach beyond 80 km without regeneration. Which technology is most appropriate?
Answer: DWDM with optical amplifiers
DWDM combined with EDFA optical amplifiers allows signal transmission well beyond 80 km without electronic regeneration.
Which network topology provides the highest resiliency for a metropolitan core network?
Answer: Full mesh topology
Full mesh topology gives every node a direct path to every other node, eliminating single points of failure.
A telecom operator is deploying small cells in a dense urban area. What backhaul technology is most commonly used when fiber is unavailable?
Answer: mmWave wireless backhaul
Millimeter-wave (mmWave) wireless backhaul provides the high capacity and low latency needed for dense urban small cell deployments when fiber isn't available.
In a carrier Ethernet network, which protocol is used to prevent loops while maintaining redundant paths?
Answer: MSTP (Multiple Spanning Tree Protocol)
MSTP prevents bridging loops in Ethernet networks while allowing multiple spanning tree instances for load balancing across VLANs.
What is the primary function of a Network Operations Center (NOC) in a telecommunications company?
Answer: 24/7 monitoring, fault management, and network restoration
A NOC provides continuous monitoring of network performance, rapid fault detection, and coordinates restoration activities to minimize outage impact.
A CTE candidate is evaluating colocation data centers for hosting core network equipment. Which factor is most critical from a network perspective?
Answer: Diverse fiber entry points and carrier-neutral interconnects
Diverse fiber entry points and carrier-neutral interconnects ensure redundant physical paths and vendor flexibility for core network equipment.
Which standard defines the Optical Transport Network (OTN) framing used in modern high-capacity transport systems?
Answer: ITU-T G.709
ITU-T G.709 defines the OTN framing structure, overhead, and client signal mapping used in modern optical transport networks.
