When can you use an Azure Resource Manager template?

  • A. to automate the creation of an interdependent group of Azure resources in a repeatable way
  • B. to apply Azure policies for multi-tenant deployments
  • C. to provision Azure subscriptions
  • D. to control which services and feature administrators and developers can deploy from the Azure portal


Answer : A

Explanation:
You can automate deployments and use the practice of infrastructure as code. In code, you define the infrastructure that needs to be deployed
To implement infrastructure as code for your Azure solutions, use Azure Resource Manager templates (ARM templates). The template is a JavaScript Object
Notation (JSON) file that defines the infrastructure and configuration for your project. The template uses declarative syntax, which lets you state what you intend to deploy without having to write the sequence of programming commands to create it. In the template, you specify the resources to deploy and the properties for those resources.

You have an Azure SQL database that you access directly from the Internet.
You recently changed the public IP address of your computer.
After changing the IP address, you can no longer access the database. You can connect to other resources in Azure.
What is a possible cause of the issue?

  • A. role-based access control (RBAC)
  • B. Dynamic Host Configuration Protocol (DHCP)
  • C. Domain Name Service (DNS)
  • D. a database-level firewall


Answer : D

Explanation:
The Azure SQL Database firewall lets you decide which IP addresses may or may not have access to either your Azure SQL Server or your Azure SQL database.
When creating an Azure SQL Database, the firewall needs to be configured before anyone will be able to access the database. By default, no external access to your SQL Database will be allowed until you explicitly assign permission by creating a firewall rule.

Box 1: Microsoft SQL Server Management Studio (SSMS)
SQL Server Management Studio (SSMS) is an integrated environment for managing any SQL infrastructure, from SQL Server to Azure SQL Database.

Box 2: Azure Data Studio -
Azure Data Studio offers a modern, keyboard-focused SQL coding experience that makes your everyday tasks easier with built-in features, such as multiple tab windows, a rich SQL editor, IntelliSense, keyword completion, code snippets, code navigation, and source control integration (Git). Run on-demand SQL queries, view and save results as text, JSON, or Excel. Edit data, organize your favorite database connections, and browse database objects in a familiar object browsing experience.
Box 3: Microsoft SQL Server Data Tools (SSDT)
SQL Server Data Tools (SSDT) is a modern development tool for building SQL Server relational databases, databases in Azure SQL, Analysis Services (AS) data models, Integration Services (IS) packages, and Reporting Services (RS) reports. With SSDT, you can design and deploy any SQL Server content type with the same ease as you would develop an application in Visual Studio.

Answer :

Explanation:

Box 1: Yes -
Tables are database objects that contain all the data in a database. In tables, data is logically organized in a row-and-column format similar to a spreadsheet.
Each row represents a unique record, and each column represents a field in the record.

Box 2: No -
An index is an on-disk structure associated with a table or view that speeds retrieval of rows from the table or view.

Box 3: Yes -
A view is a virtual table whose contents are defined by a query. Like a table, a view consists of a set of named columns and rows of data.
