Question 1

A telecom executive is evaluating cloud providers for 5G core deployment. Which factor is most critical from a latency perspective?

Accepted Answer

Proximity of cloud edge nodes to RAN sites

Answer

5G requires ultra-low latency, so the physical proximity of cloud edge compute to RAN sites is the dominant latency factor.

Question 2

What is the role of a Service Mesh in cloud-native telecom applications?

Accepted Answer

It manages inter-service communication, observability, and security within microservices

Answer

A service mesh (e.g., Istio) handles east-west traffic management, mTLS security, and telemetry between microservices without code changes.

Question 3

Which cloud resilience strategy involves distributing active workloads across multiple availability zones simultaneously?

Accepted Answer

Active-active deployment

Answer

Active-active deployment runs identical workloads in multiple zones simultaneously, providing both load distribution and instant failover.

Question 4

In cloud infrastructure for telecommunications, what does 'auto-scaling' primarily address?

Accepted Answer

Dynamically adjusting compute capacity based on real-time demand

Answer

Auto-scaling automatically provisions or removes compute instances based on predefined metrics like CPU usage or request rate.

Question 5

What distinguishes a 'microservices' architecture from a 'monolithic' architecture in telecom BSS/OSS modernization?

Accepted Answer

Microservices decompose applications into independently deployable, loosely coupled services

Answer

Microservices break applications into small, independent services each responsible for a specific business function, enabling independent scaling and deployment.
