Nokia Certified Associate – Bell Labs Learning Academy — Question 9

Which of the following drive 5G higher reliability?

Answer options

• A. Higher spectral efficiency
• B. Multi-connectivity per User Equipment
• C. Connectionless radio access
• D. Lower Time Transmission Interval (TTI)

Correct answer: A

Explanation

Higher spectral efficiency allows more data to be transmitted over a given bandwidth, enhancing reliability. While multi-connectivity and lower TTI can improve performance, they do not directly drive reliability as effectively as increased spectral efficiency does. Connectionless radio access is more about reducing latency than improving reliability.
