Free Cloud-Digital-Leader sample questions

Correct answer: From CapEx to OpEx, allowing them to pay only for resources consumed.

Cloud computing shifts IT spending from Capital Expenditure (CapEx), where hardware is bought upfront and depreciated, to Operational Expenditure (OpEx), where services are paid for as they are consumed (pay-as-you-go). This increases financial agility and removes long-term asset lock-in.

Correct answer: IaaS (Infrastructure as a Service)

In an Infrastructure as a Service (IaaS) model, the cloud provider manages the physical hardware, networking, and virtualization. The customer is responsible for the operating system, middleware, runtime, data, and applications. This fits the requirement of needing OS-level control without managing physical servers. graph TD subgraph Provider["Provider Manages"] Hard[Hardware] Virt[Virtualization] end subgraph Customer["Customer Manages"] OS[Operating System] Middle[Middleware] Run[Runtime] App[Application] Data[Data] end Provider --> Customer

Correct answer: A web server farm automatically adds instances during a Black Friday sale and removes them when traffic subsides.

Elasticity is the ability of a system to automatically scale resources out (add) and in (remove) to match demand. This dynamic adjustment ensures performance during peaks and cost savings during troughs, unlike simple scalability which often refers to just growing.

Correct answer: Hybrid Cloud

A Hybrid Cloud deployment combines a private environment (on-premises) with a public cloud (Google Cloud), allowing data and applications to share resources between them. This is ideal for meeting regulatory compliance (keeping data private) while leveraging public cloud innovation. graph LR subgraph OnPrem["On-Premises Germany"] Data["Sensitive Data Compliance Zone"] end subgraph GCP["Google Cloud Processing"] Anon["Anonymize"] AI["AI Compute"] end Data -->|After Anonymization| Anon Anon --> AI AI -->|Results| Data style OnPrem fill:#e1f5ff style GCP fill:#f1f8e9

Correct answers: It prevents vendor lock-in by allowing portability of code and workloads.; It enables community-driven innovation and faster development cycles.

Open source software allows code to be inspected, modified, and run on any compatible infrastructure, significantly reducing the risk of being locked into a single vendor's proprietary ecosystem.

Open source projects benefit from a global community of developers contributing improvements, security patches, and features, often leading to faster innovation compared to closed, proprietary teams.

Correct answer: False

False. Even in SaaS, the customer retains responsibility for data governance, identity and access management (who can access the software), and endpoint security. The provider handles the app, infrastructure, and OS, but 'Content' and 'Access' remain with the customer.
