Infrastructure Implementation and Operations Questions

Hands on design, deployment, and operational management of infrastructure components and services. This includes setting up and configuring load balancers, database replication and high availability, caching layers, networking and network security, service discovery and routing, container deployment and orchestration, monitoring and observability, logging and alerting, backup and disaster recovery strategies, and secrets management in runtime. Candidates should be able to walk through concrete implementations, explain trade offs, demonstrate troubleshooting and performance tuning, and show how infrastructure components integrate to meet availability, scalability, and security requirements.

Design a multi-region ingestion pipeline for IoT data with local low-latency writes in each continent and a single global analytics view. Discuss routing, local buffering, eventual consistency, reconciliation, and how you'd handle time synchronization and duplicate events.

Compare envelope encryption (data keys wrapped by cloud KMS) versus client-side encryption for a data lake storing PII. Discuss key management complexity, performance overhead, searchability/indexing, auditability, and regulatory compliance implications.

Design tracing and distributed context propagation for a data platform running mixed workloads (serverless functions, Spark, microservices). Explain how spans are created, propagated across boundaries (HTTP, messaging, storage), sampled, stored, and queried to enable root-cause analysis for a failing pipeline.

Compare columnar and row-oriented storage for analytical datasets. For a partitioned Parquet-based data lake targeted at ad-hoc analytics, recommend partitioning strategy, ideal file size range, and compaction approach to optimize query performance and cost.

Explain the difference between a Kubernetes Deployment, ReplicaSet, and StatefulSet. For running Kafka Connect or a persistent metadata service, which controller would you choose and why? Mention stability of network IDs, storage, and scaling implications.
