TELCOMA Certified 5G Core & E2E Specialist

What's assessed

8 domains, 56 questions in total — drawn from the course lessons.

• Core Procedures Deep Dive

  7 questions

  Reading any call flow, then tracing them message by message: registration end to end, PDU session establishment, session modification and release including sessions that sleep, and N4/PFCP as the SMF drives the UPF.

• QoS, Policy & Charging

  7 questions

  Building a QoS design from SLA down to 5QI — QoS flows in depth, the PCF as the network's rulebook, charging through the CHF, and engineering a service-level agreement end to end.

• Network Slicing

  7 questions

  Designing and defending a slice architecture: what a slice really is, how the S-NSSAI identifies it, slice selection step by step, keeping slices apart on the air, and exposing them through the NEF.

• Edge & Cloud-Native Operations

  7 questions

  Placing workloads for latency and running the core like software: MEC and local breakout, how UPF placement sets the latency budget, containers and orchestration, service mesh, and observability with NWDAF.

• 5G Security

  7 questions

  The trust chain from SIM to roaming partner: why 5G trusts nothing, 5G-AKA step by step, the key hierarchy from long-term secret down, NAS and AS security, and SEPP at the roaming border.

• Voice, Messaging & Devices

  7 questions

  How calls and texts ride a data-only network: what IMS is and why 5G reuses it, VoNR call setup, EPS fallback as the safety net, SMS over NAS and RCS, and RedCap devices.

• 5G-Advanced, Now

  7 questions

  What Rel-18 and Rel-19 make possible today: the 5G-Advanced map, AI/ML across the network including AI-RAN and NWDAF-driven automation, NTN from space, XR services, and positioning, sensing groundwork and energy.

• The Road to 6G + Capstone

  7 questions

  Holding an informed 6G conversation — the six IMT-2030 usage scenarios, Rel-20 studies and the path to Rel-21, research frontiers including ISAC, AI-native, FR3 and sub-THz, and a final end-to-end build.
