Question 1

Which generation of wireless technology introduced network slicing as a core capability to support diverse use cases such as eMBB, URLLC, and mMTC?

Accepted Answer

5G NR

Answer

5G NR (New Radio) introduced network slicing to allow a single physical network to be partitioned into multiple virtual networks optimized for different service types.

Question 2

In the context of IoT deployments in US telecom networks, what does NB-IoT stand for?

Accepted Answer

Narrowband Internet of Things

Answer

NB-IoT stands for Narrowband Internet of Things, a low-power wide-area network technology standardized by 3GPP for connecting devices that require small amounts of data over long periods.

Question 3

What is the primary role of Multi-access Edge Computing (MEC) in modern telecommunications networks?

Accepted Answer

Moving compute and storage resources closer to the network edge to reduce latency

Answer

MEC moves compute and storage to the network edge, reducing round-trip latency and enabling real-time applications like autonomous vehicles and AR/VR.

Question 4

Which Open RAN (O-RAN) interface connects the RU (Radio Unit) to the DU (Distributed Unit) in a disaggregated 5G radio architecture?

Accepted Answer

Fronthaul (eCPRI)

Answer

The fronthaul interface, commonly implemented with eCPRI (enhanced Common Public Radio Interface), connects the Remote Radio Unit to the Distributed Unit in O-RAN architecture.

Question 5

A CTE is evaluating AI-driven network operations (AIOps) for a US carrier. Which primary benefit justifies the investment in AIOps for fault management?

Accepted Answer

Predictive anomaly detection to resolve issues before customer impact

Answer

AIOps uses machine learning to detect anomalies and predict failures proactively, allowing operators to resolve issues before they affect customers and reduce mean time to repair.
