The cloud computing model in which the infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers is called ________.
- Community Cloud
- Hybrid Cloud
- Private Cloud
- Public Cloud
A Private Cloud is established exclusively for a single organization, offering dedicated infrastructure to ensure security and control over cloud resources.
Which of the following best describes the architecture of modern cloud-based analytics tools?
- Legacy, Proprietary, and Limited Data Sources
- Monolithic, On-Premises, and Batch Data Processing
- Serverless, Scalable, and Distributed Data Processing
- Single-Tenant, Centralized, and Traditional Data Warehousing
Modern cloud-based analytics tools typically feature a serverless, scalable, and distributed architecture to handle diverse data processing workloads efficiently.
Which part of a cloud computing system is directly accessed and interacted with by the user?
- Cloud Service
- Data Center
- User Interface
- Virtual Machine
The "User Interface" is the component of a cloud computing system that users directly access to interact with the cloud services, applications, and data.
One of the primary reasons for unexpected cloud costs is ________.
- Cloud Security
- Cost Allocation
- Data Backup Policies
- Overprovisioning
Overprovisioning, or allocating more resources than necessary, can lead to unexpected cloud costs. It's essential to right-size resources to avoid unnecessary expenses while ensuring adequate performance.
The concept of accessing computing resources over the internet is closely related to:
- Social networking sites
- Internet of Things (IoT)
- E-commerce
- Cloud Services
Accessing computing resources over the internet is the foundation of cloud services. While the other options do use the internet, they don't represent the idea of harnessing computing power and resources directly over the internet in the same way cloud services do.
Which of the following is a popular analytics tool offered by Amazon Web Services?
- Amazon Athena
- Amazon Elastic Compute Cloud (EC2)
- Amazon Relational Database Service (RDS)
- Amazon S3 (Simple Storage Service)
Amazon Athena is a serverless, interactive query service offered by AWS for querying data in Amazon S3 using SQL. It's a popular choice for ad-hoc data analysis and exploration.
Kubernetes is best described as:
- Cloud Hosting Service
- Container Orchestration System
- Database Management System
- Virtualization Platform
Kubernetes is best described as a container orchestration system. It automates the deployment, scaling, and management of containerized applications.
In the context of virtualization, what is "paravirtualization"?
- A method to create virtual machines
- A technique to emulate hardware devices
- A technology to enhance graphics performance
- A virtualization technique where the guest OS is modified to be aware of the virtualization layer
Paravirtualization involves modifying the guest OS to work more efficiently with the hypervisor, improving performance and allowing for efficient communication with the host.
A ________ is a software layer that abstracts the physical hardware to create multiple virtual machines.
- Compiler
- Debugger
- Hypervisor
- Kernel
A Hypervisor is a crucial software layer that manages virtual machines by abstracting and controlling access to physical hardware resources. It enables the creation of multiple VMs on a single physical server.
One of the main benefits of using cloud services for AI and ML is the availability of large-scale ________ for training complex models.
- Data storage and processing
- E-commerce websites
- IoT devices
- Social media platforms
Cloud providers offer extensive data storage and processing capabilities, enabling users to access large datasets for training complex AI and ML models. This resource scalability is a significant benefit.
