Technology – GK Questions

Q: Which practice involves intentionally injecting failures to test system resilience?

Chaos Engineering – Chaos Engineering (Netflix Chaos Monkey) proactively tests system resilience by injecting failures in controlled experiments. Builds confidence in fault tolerance.

Q: GitOps uses Git repositories as single source of truth for infrastructure and application deployments.

True – GitOps (ArgoCD, Flux) declaratively defines desired state in Git; operators sync cluster state. Benefits: audit trail, rollback via git revert, peer review via PRs.

Q: The practice of defining infrastructure and configuration in version-controlled code files is called Infrastructure as ________.

Code – IaC (Terraform, Ansible, CloudFormation) defines infrastructure in declarative code, enabling version control, peer review, automated testing, consistent deployments.

Q: Which pattern isolates external system interactions for testability?

Both A and B – Adapter/ACL patterns wrap external APIs, translating between internal models and external interfaces. Critical for maintainable integrations and testing.

Q: Which database feature enables automatic distribution of data across multiple nodes for scalability?

Sharding – Sharding partitions data horizontally across nodes based on key ranges or hashes, enabling horizontal scaling. Critical for handling large datasets in distributed databases.

Q: Edge computing processes data closer to source to reduce latency for IoT applications.

True – Edge computing brings computation to network edge (routers, gateways), enabling real-time processing for IoT, autonomous vehicles, industrial automation. Complements cloud.

Q: The technology that enables machines to learn from experience without explicit programming is called ________ Learning.

Machine – Machine Learning enables systems to learn patterns from data and improve performance on tasks without explicit programming. Types: supervised, unsupervised, reinforcement.

Q: Which program provides funding and mentorship to early-stage deep tech startups?

All of these – NIDHI-PRAYAS (DST) funds prototyping; Startup India offers tax benefits; AIM establishes incubators. Together support innovation from ideation to scale.

Q: Digital twins create virtual replicas of physical systems for simulation and optimization.

True – Digital twins combine IoT, AI, simulation to model physical assets: factories, cities, power grids. Enables predictive maintenance, scenario testing. Critical for Industry 4.0.

Q: Which technology enables immersive virtual experiences through head-mounted displays?

All of these – Immersive tech: VR (fully virtual), AR (overlay on real world), MR (blend virtual/real). Applications: training, education, entertainment, remote collaboration.
