10. What is Azure Data Factory?
Azure Data Factory is Azure’s cloud ETL service for serverless and cloud-based data integration and data transformation. It offers a code-free UI for intuitive authoring, prompt monitoring, and administration. In addition, the service aims to formulate data-driven workflows for the preparation and execution of data movements.
11. What is the use of Azure Active Directory?
Azure Active Directory (Azure AD) is an identity management and multi-factor authentication service offered by Azure. It allows you to grant your employees access to specific products and services within the network and protect the users from cyberattacks.
12. What are the different cloud deployment models?
Cloud deployment models are a type of virtual computing environment that authorize you to decide how much data is to be shared and decide who gets access to the whole system.
There are usually four types of deployment models, i.e., –
Public cloud: As the name suggests, it is accessible by the public and enables cloud services across the public internet and server. This model is excellent for organizations with growing and fluctuating demands and companies with low-security concerns.
Private cloud: Here, the cloud computing services are offered either over the private internal network or the internet platform available to the selected users. A private cloud model is integrated with a company’s data center and managed by its IT team. It is beneficial for companies looking for cost efficiency and wanting more control over their data and resources.
Hybrid cloud: It is a combination of two or more cloud architectures, and within this cloud system, the internal or external providers can offer resources.
Community Cloud: It is similar to the public cloud with only one difference, i.e., it allows access to a limited set of users who share similar goals and use cases.
13. Name three types of Disks used by VMs.
- Operating system disk
- Temporary disk
- Data disk
14. What is a Fault Domain?
A fault domain is a group of hardware that share a common power source, or basically, a single point of failure. Each fault domain consists of some racks and virtual machines that are distributed across the Azure platform.
15. What is Enterprise Warehousing?
Enterprise warehousing is a scenario in which data is generated by an organization that has access at a single point within the globe. It allows linking the serving to a single position with the support of periodic handling.
16. What are the types of services you can build with the Service Fabric?
With Azure Service Fabric, you can build two types of services –
- Stateless Services: In these services, no state is saved, and the longer-term state is stored in some external database. This is the most common application/data layer approach to building services.
- Stateful Services: As the name suggests, the state is stored in this type of service. The main benefit of this service is that it eliminates the need for an external database.
17. What are the differences between a Subscription Administrator and a Directory Administrator?
When you sign up for Azure, you are assigned the role of a Subscription Administrator by default. As a Subscription Admin, you can use a personal Microsoft account or a work or institution’s account to manage all the services in the Azure Portal. Plus, you can add others as co-admins if the job requires them to sign in and access services.
Azure Directory Administrator, on the other hand, has to manage the directory and identity-related features. Therefore, if you are an Azure DA, you will have access to several features in the Azure portal, and your responsibilities and tasks will depend on your role. For example, you might have to create or edit users, assign roles to others, reset passwords, and maintain user licenses and domains.
18. What are the services used to manage resources in Azure?
- Application Insights
- Azure Portal
- Azure Resource manager
- Log Analytics
19. Explain some of the drawbacks of using Microsoft Azure.
- The first major drawback of Azure is that it does not allow cloud computing if you are not able to connect to the Internet.
- Secondly, it is a web-based application and needs a lot of bandwidth to download large documents.
- And lastly, web-based applications are sometimes slower as compared with a similar software program on the computer.
