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

    Answer: 5G NR

    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.

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

    Answer: Narrowband Internet of Things

    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.

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

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

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

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

    Answer: Fronthaul (eCPRI)

    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.

  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?

    Answer: Predictive anomaly detection to resolve issues before customer impact

    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.

  6. What is a digital twin in the context of telecommunications network management?

    Answer: A virtual replica of a physical network used for simulation and testing

    A digital twin is a virtual model of a physical network that mirrors real-time conditions, enabling operators to simulate changes, test configurations, and predict outcomes without impacting production.
