When optimizing costs for cloud services, what does the term "Right-sizing" refer to?
- Automatically managing resources to save costs
- Matching resource requirements to workload demands
- Reducing security risks
- Scaling horizontally
"Right-sizing" means matching the resources (e.g., CPU, memory) to the workload's actual demands, preventing over-provisioning and unnecessary costs.
When deploying AI services in the cloud, what is the significance of edge computing, especially concerning IoT devices?
- Enhanced cloud scalability
- Improved model complexity
- Increased cloud cost
- Reduced latency
Edge computing significantly reduces latency for AI services in IoT. Processing data closer to the source (IoT device) minimizes the time it takes for results, critical in real-time applications.
How does AWS Lambda handle concurrency and scaling when there are multiple invocations?
- Automatic Scaling
- Connection Pools and Queues
- Manual Scaling and Capacity Planning
- Throttling and Rate Limiting
AWS Lambda automatically handles concurrency and scaling. It dynamically allocates resources to accommodate multiple invocations, ensuring that the desired number of simultaneous executions are maintained.
Which of the following best describes the purpose of Identity and Access Management?
- Controlling and securing access
- Ensuring data accuracy
- Optimizing data storage
- Protecting data from physical harm
The purpose of Identity and Access Management is to control and secure access to systems and data, ensuring only authorized users have access.
A group of non-profit organizations focused on wildlife conservation wants to share resources and data in a cloud environment without making it accessible to external entities. What type of cloud model should they consider?
- Private Cloud
- Public Cloud
- Hybrid Cloud
- Community Cloud
To ensure data privacy for non-profit organizations sharing resources in a cloud environment, a "Private Cloud" is the best option. It offers exclusive control over data and resources, making it inaccessible to external entities.
What is the primary difference between a Docker image and a Docker container?
- Containers are lightweight, images are heavy
- Images are for building, containers are for running
- Images run applications, containers store data
- Images store runtime data, containers store source code
Docker images are read-only templates used to create containers. Containers are instances of images that run applications. Images are for building and containers are for running.
In the context of Google Cloud Functions, what is the significance of "idempotent retries"?
- Ensuring reliability
- Handling cold starts
- Implementing triggers
- Reducing billing costs
"Idempotent retries" ensure that even if a request is retried, the system remains in a consistent state, essential for maintaining data integrity and reliability.
Community clouds are primarily designed to address the needs of:
- A specific industry or community
- Government agencies
- Individual consumers
- Large multinational corporations
Community clouds are designed to serve a specific community or industry, enabling them to share resources and comply with specific regulations and standards.
Azure's managed Kubernetes service is abbreviated as ________.
- A-Kube-Service
- AKS
- Azure Kube-Manager
- K8S
Azure's managed Kubernetes service is abbreviated as AKS, which stands for Azure Kubernetes Service. It simplifies deploying, managing, and scaling containerized applications using Kubernetes.
One of the primary benefits of using cloud-based analytics tools like AWS Redshift or Google BigQuery is the ability to scale ________.
- Elastically
- Horizontally
- Statically
- Vertically
Cloud-based analytics tools provide the ability to scale "elastically" by dynamically adjusting resources to meet demand, a key feature for handling varying workloads.
