Read the first 7 Cloud Infrastructure flashcards as text

  1. 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.

  2. 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.

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. 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.
