A telecom executive is evaluating cloud providers for 5G core deployment. Which factor is most critical from a latency perspective?
Answer: Proximity of cloud edge nodes to RAN sites
5G requires ultra-low latency, so the physical proximity of cloud edge compute to RAN sites is the dominant latency factor.
What is the role of a Service Mesh in cloud-native telecom applications?
Answer: It manages inter-service communication, observability, and security within microservices
A service mesh (e.g., Istio) handles east-west traffic management, mTLS security, and telemetry between microservices without code changes.
Which cloud resilience strategy involves distributing active workloads across multiple availability zones simultaneously?
Answer: Active-active deployment
Active-active deployment runs identical workloads in multiple zones simultaneously, providing both load distribution and instant failover.
In cloud infrastructure for telecommunications, what does 'auto-scaling' primarily address?
Answer: Dynamically adjusting compute capacity based on real-time demand
Auto-scaling automatically provisions or removes compute instances based on predefined metrics like CPU usage or request rate.
What distinguishes a 'microservices' architecture from a 'monolithic' architecture in telecom BSS/OSS modernization?
Answer: Microservices decompose applications into independently deployable, loosely coupled services
Microservices break applications into small, independent services each responsible for a specific business function, enabling independent scaling and deployment.
Which cloud security principle ensures that telecom application components only have access to the minimum resources needed to perform their functions?
Answer: Principle of least privilege
The principle of least privilege limits each component's access rights to only what is strictly necessary, reducing the blast radius of any compromise.
A telecom operator uses Infrastructure as Code (IaC) for its cloud deployments. What is the primary benefit of this approach?
Answer: It enables reproducible, version-controlled, and automated infrastructure provisioning
IaC codifies infrastructure configuration, enabling version control, peer review, automated testing, and consistent repeatable deployments.
