5G Technical Practice Quiz & Certification Arena
Engineers looking to validate their telecom competence, prepare for technical job interviews, or assess their knowledge of 3GPP standards can challenge themselves in the 5G6GTech Quiz Arena. Questions test architectural discernment, protocol procedures, and system tradeoffs rather than superficial memorization.

Sample 5G Quiz Question
PRACTICE QUESTION #1 • 3GPP TS 38.211
In 5G New Radio, if a carrier is configured with subcarrier spacing numerology μ = 2 (60 kHz SCS), what is the duration of one radio slot?
A) 1.0 ms
B) 0.5 ms
C) 0.25 ms (Correct)
D) 0.125 ms
Specification Rationale: In 3GPP TS 38.211, slot duration is 1 ms / 2^μ. For μ = 2 (60 kHz SCS), slot duration = 1 ms / 4 = 0.25 ms. There are 4 slots per 1 ms subframe, and each slot contains 14 OFDM symbols.
