Microsoft Certified: Azure Fundamentals Practice Questions: Azure Core Services Domain

Correct Answer: undefined

Explanation: Azure Resource Manager (ARM) is the deployment and management service for Azure. It provides a consistent management layer that enables you to create, update, and delete resources in your Azure account programmatically. ARM templates allow you to automate the deployment of infrastructure as code. Azure DevOps is for CI/CD pipelines, Azure Automation is for process automation, and Azure Policy is for enforcing standards and assessing compliance.

Correct Answer: undefined

Explanation: Azure Blob Storage is designed for storing large amounts of unstructured data, such as images, videos, and backups. It is optimized for data access and storage. Azure SQL Database (A) is used for structured data, Azure Functions (C) is for serverless computing, and Azure Virtual Network (D) is for networking solutions.

Correct Answer: undefined

Explanation: Azure Blob Storage is designed for storing large amounts of unstructured data such as binary files, media files, and backups. Azure Table Storage (A) is for structured NoSQL data, Azure File Storage (C) offers managed file shares, and Azure Queue Storage (D) is for message queuing.

Correct Answer: undefined

Explanation: Azure Cosmos DB is a globally distributed, multi-model database service that provides high availability and scalability. Blob Storage is for storing unstructured data, Virtual Network is for networking, and DevOps is for development and operations practices.

Correct Answer: undefined

Explanation: Azure Load Balancer distributes incoming network traffic across multiple VMs, improving application availability. It is not used for data storage (A), serverless applications (C), or identity management (D).

Correct Answer: undefined

Explanation: Azure Monitor helps you maximize the availability and performance of your applications by collecting, analyzing, and acting on telemetry data. Azure Functions is for serverless compute, DevOps is for development operations, and Active Directory is for identity management.

Correct Answer: undefined

Explanation: Azure App Service is a fully managed platform for building, deploying, and scaling web apps. It allows you to host web applications without managing the underlying server infrastructure, which makes it ideal for developers who want to focus on building their application rather than maintaining servers. Azure Virtual Machines require you to manage the server infrastructure, Azure Functions is more suited for event-driven serverless applications, and Azure Kubernetes Service is for container orchestration.

Correct Answer: undefined

Explanation: Azure Cosmos DB is a globally distributed, multi-model database service designed to provide high availability, low latency, and scalability. It supports various data models such as document, key-value, graph, and column-family. Running VMs (A), hosting web apps (B), and storing binary objects (D) are not the primary use cases.

Correct Answer: undefined

Explanation: Azure Stream Analytics is a real-time analytics service that is designed to process and analyze streaming data from multiple sources simultaneously. It is ideal for scenarios such as real-time fraud detection, clickstream analysis, and social media analytics. Azure Data Lake is for big data storage, Azure SQL Database is a relational database service, and Azure Data Factory is used for data integration and orchestration.

Correct Answer: undefined

Explanation: Azure Virtual Machines (VMs) allow users to run virtualized operating systems in the cloud. They are primarily used for scenarios where users need to deploy and manage applications just like they would on a physical server. Options A, C, and D describe other Azure services like App Services, Azure SQL Database, and Azure Logic Apps, respectively.
