Which of the following best describes the relationship between IoT and the Cloud?
- IoT devices are entirely separate from the cloud
- IoT devices connect directly to the cloud
- IoT devices use the cloud for data storage and analysis
- IoT devices use the cloud for power supply
The relationship between IoT and the Cloud is that IoT devices use the cloud for data storage and analysis. IoT devices generate a vast amount of data, and the cloud provides the infrastructure for storing and processing this data efficiently.
SaaS applications typically offer extensive ________ capabilities to cater to a diverse set of customers.

- Load Balancer
A Container Registry is essential to store, version, and retrieve containerized applications, ensuring they are available for deployment in the CI/CD pipeline.
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.
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.
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.
