TELCOMA Certified 5G Foundation

What's assessed

7 domains, 49 questions in total — drawn from the course lessons.

• The 5G Big Picture

  7 questions

  What 5G changed and for whom: the eMBB/URLLC/mMTC use-case triangle and which parts actually shipped, plus who sets the rules — 3GPP, ITU, GSMA and the O-RAN Alliance.

• Cellular Foundations

  7 questions

  The vocabulary 5G builds on: cells, sectors and frequency reuse; spectrum bands, licensing and FDD versus TDD; what each generation from 1G to 4G solved; and the four limits 5G had to break.

• 5G System Architecture

  7 questions

  The whole system from memory: the RAN, Core and Data Network domains, NSA versus SA and the options that shipped, inside the gNB, and the N1–N6 and Xn reference points.

• Service-Based Architecture

  7 questions

  Why the 5G core is an API platform: SBI mechanics over HTTP/2 and JSON, the NRF, AMF and SMF for mobility and sessions, AUSF/UDM/PCF/NSSF/NEF, and CUPS with the UPF as the user-plane workhorse.

• Radio & Spectrum Fundamentals

  7 questions

  Reading a spectrum chart and the trade-offs behind it: FR1 versus FR2 strategy, OFDM without the maths, QAM/MCS/HARQ, a first pass at MIMO and beamforming, and coverage against capacity.

• Connecting to the Network

  7 questions

  Power-on to first packet: the SUPI, SUCI and 5G-GUTI identities and the privacy they buy, RRC idle/inactive/connected, registration step by step, and PDU sessions with the QoS flows that carry your data.

• Foundation Consolidation

  7 questions

  Pulling it together — a first look at network slicing, 5G myths against measured reality, and the full-system diagram rebuilt from scratch.
