CDL Sample Questions & Answers

This statement is true. In an IaaS model, the cloud provider manages the physical hardware, networking, and virtualization layer. The customer takes responsibility from the operating system upwards, including OS patching, network firewall rules, platform software, and the application and its data.

Cloud Run is the ideal choice as it is a fully managed serverless platform that runs stateless containers. It directly meets the requirements by abstracting away all infrastructure management (minimizing operational overhead), scaling automatically based on requests, and scaling down to zero, which means the company only pays when the service is actively handling traffic.

The principle of 'freedom' in Google Cloud refers to its commitment to open standards and open source technologies (like Kubernetes, TensorFlow, and Istio). This approach gives customers the flexibility to run their applications on Google Cloud, on-premises, or in other clouds, thereby preventing vendor lock-in and allowing them to innovate on their own terms.

In BigQuery's on-demand pricing model, cost is calculated based on the number of bytes processed by the query. This includes all the data read from the tables referenced in the query, regardless of the amount of data returned. Therefore, to manage costs, analysts should write queries that select only the columns they need and use partitioning or clustering to reduce the amount of data scanned.

The Principle of Least Privilege is a fundamental security concept that is implemented using Identity and Access Management (IAM). It dictates that a user should have the minimum levels of access – or permissions – needed to perform their job. Google Cloud IAM enables fine-grained control to enforce this principle by assigning specific roles to identities (users, groups, service accounts) for particular resources.

Google Cloud's sustainability benefit stems from its long-standing commitment to carbon neutrality and its goal to run on carbon-free energy 24/7. When customers run their workloads on Google Cloud, those workloads inherit these green credentials. Additionally, Google provides tools like Carbon Footprint, which helps organizations measure, report, and reduce the carbon emissions of their cloud usage, supporting their own sustainability goals.

A primary business advantage of a microservices architecture is organizational agility. By breaking a large application into smaller, independent services, different teams can work on their respective services in parallel. This allows for independent deployment cycles, technology choices, and scaling, which significantly speeds up the delivery of new features and improves the application's overall resilience, as a failure in one service is less likely to bring down the entire system.

Google Cloud addresses data sovereignty and residency requirements through its global infrastructure of regions. A region is a specific geographical location where customers can deploy resources. By choosing a region located within the required country (e.g., the 'europe-west2' region in London, UK), the agency can ensure that its data is stored and processed within that country's borders, thus complying with local laws.

Looker promotes 'data democratization' by using a centralized, reusable data model called LookML. This model, typically created by data engineers, defines business logic and metrics once. Business users, like the analyst, can then use a simple point-and-click interface to explore this governed data, create visualizations, and build dashboards without writing SQL or needing constant help from the data team. This enables self-service analytics and faster insights.

The primary business value of monetizing APIs is strategic: it transforms an organization's data and services into products. This allows the company to create new revenue streams, foster innovation by enabling an ecosystem of external developers and partners to build on their platform, and expand their market reach. Apigee provides the necessary security, analytics, and management capabilities to make this possible.
