8. How Microsoft use to determine Azure costs for each billing period
Ans. Usage meters are used to determine Azure costs for each billing period.
9. An Azure subscription is a logical unit of Azure services that is linked to an Azure account. Is it correct statement
Ans. Yes
10. Which Azure Service provides development collaboration tools including high-performance pipelines, free private Git repositories, configurable Kanban boards, and extensive automated and cloud-based load testing.
Ans. Azure DevOps
11. What is Serverless computing
Ans. Serverless computing is a cloud-hosted execution environment that runs your code but abstracts the underlying hosting environment. You create an instance of the service and you add your code. No infrastructure configuration or maintenance is required, or even allowed.
12. Which Service Azure provides as Serverless service
Ans. Azure Function Apps, Azure Logic Apps
13. What is Azure HDInsight
Ans. Azure HDInsight is a fully managed, open-source analytics service for enterprises. It is a cloud service that makes it easier, faster, and more cost-effective to process massive amounts of data. HDInsight allows you run popular open-source frameworks and create cluster types such as Apache Spark49, Apache Hadoop50, Apache Kafka51, Apache HBase52, Apache Storm53, Machine Learning Services54
14. What is Azure Data Lake Analytics
Ans. Azure Data Lake Analytics is an on-demand analytics job service that simplifies big data. Instead of deploying, configuring, and tuning hardware, you write queries to transform your data and extract valuable insights.
15. Which type of storage can manage thousands of simultaneous uploads, massive amounts of video data, constantly growing log files, and can be reached from anywhere with an internet connection.
Ans. Azure Blob Storage
Azure DevOps
16. What is Azure DevOps
Ans. Azure DevOps Services allows you to create, build, and release pipelines that provide continuous integration, delivery, and deployment for your applications. You can integrate repositories and application tests, perform application monitoring, and work with build artifacts. You can also work with and backlog items for tracking, automate infrastructure deployment, and integrate a range of third-party tools and services such as Jenkins and Chef.
17. CI/CD Pipeline can be created in Azure DevOps using
Ans. Azure Pipeline
18. Azure DevOps supports Build and Release which can be configured using ?
Ans. Azure Pipeline
19. In Azure DevOps Continuous Integration, includes the integration of multiple ?
Ans. Builds
20. Which tools are supports for Continuous Integration?
Ans. Azure Pipelines has support for all the platform like Linux, macOS and Windows and some of the tools that can be used for the Continuous Integrations are Jenkins, Bamboo, GitLab CI, CircleCI are some of the examples.
20. What services Azure DevOps Provides
Ans. Azure DevOps provides full application lifecycle management from planning to coding, and from testing to build and deploy
21. In Azure DevOps, Release pipeline is created on the top of what
Ans. Build pipeline
22. Which component of Azure DevOps act as a “online code repository with version control”
Ans. Azure Repos
23. What are Azure Repos
Ans. Azure Repos is a code version control system that can manage your code and its version.
24. What type of version control system supported by Azure Repos
Ans. Azure Repos supports Centralized version control system and distributed version control system.
25. Which is the default version control mechanism of Azure Repos
Ans. Git (distributed version control system)
26. Which services of Azure DevOps provides for project management
Ans. Azure Boards
27. In Azure DevOps the “yml” configuration file is associated with which DevOps component
Ans. Azure Pipeline
28. What is version controlling systems
Ans. Version control systems are a category of software tools that helps record changes to files by keeping a track of modifications done to the code
29. Continuous integration, Continuous delivery, and Continuous deployment
Ans. Continuous integration (CI) is a practice in which code versions are continuously integrated into a shared repository. Continuous delivery takes CI one step further by ensuring that after integration, the code base is ready to be released any time. Continuous deployment will have all updates in the code automatically deployed to the production environment immediately after the testing phase without any human intervention.
30. Azure DevOps is offered by Microsoft on Azure Cloud. It falls under which cloud service model
Ans. SaaS
Azure Agile
31. What is Agile
Ans. Agile gives you some values and principles where a team can decide what to do and what to use. Agile is not a methodology rather it provides various methodology that a team can use in order to follow Agile values and principles. So AGILE is a practice that promotes continuous iteration of development and testing throughout the software development lifecycle of the project.
32. In one line tell about DevOps vs. Agile
Ans. Both DevOps and agile are modern software development practices aimed at providing a framework to produce a part of a product, a launch, or a release. DevOps versus agile is that they are not mutually exclusive.
33. Difference between DevOps vs. Agile
Ans.
34. How DevOps and agile work together
Ans. Both DevOps and agile offer a structure and framework that can speed software delivery. You do not need to choose between DevOps or agile—instead, you can make use of both methodologies. Agile is strong on methods to organise work, such as through Scrum or Kanban and DevOps drives a broader culture of getting software delivered faster and more reliably.
35. What is Scrum
Ans. The Scrum methodology follows the values and principles of agile. Scrum is an agile project management methodology or framework used primarily for software development projects with the goal of delivering new software capability every 2-4 weeks.
Azure Data Factory
36. What is integration runtime
Ans. The integration runtime is the compute infrastructure that Azure Data Factory uses to provide the data integration capabilities across various network environments:
37. Types of Integration runtime
Ans. There are three types
i) Azure Integration Run Time: Azure Integration Run Time can copy data between cloud data stores and it can dispatch the activity to a variety of compute services such as Azure HDinsight or SQL server.
ii) A Self Hosted IR can run copy activities between a public cloud data store and a data store in a private network. It can also dispatch transformation activities against compute resources in a private network.Eg On-Premises or Azure VM
iii) Azure SSIS Integration Run Time: The integration runtime natively executes SSIS packages in a managed Azure compute environment.
38. What are the four key components of Azure Data Factory
Ans. Pipelines, DataSets, Linked Services, Activities
39. How can I schedule a pipeline?
Ans. You can use the scheduler trigger or time window trigger to schedule a pipeline
40. What is the difference between Azure Data Lake store and Blob storage?
Ans. Azure Data Lake Storage: Optimized storage for big data analytics workloads with Hierarchical file system where as Azure Blob Storage: General purpose object store for a wide variety of storage scenarios, including big data analytics but object store with flat namespace.
