Azure Developer Associate (D306)

Correct Answer

C. JSON

Explanation

Azure Resource Manager (ARM) templates are written in JSON (JavaScript Object Notation). JSON provides a lightweight, structured, and human-readable format that defines the infrastructure and configuration for Azure deployments. ARM templates describe resources and their properties, dependencies, and configurations in a declarative way, making them ideal for infrastructure-as-code scenarios.

Why other options are wrong

A. XML

While XML has been used in older Microsoft technologies, ARM templates do not use XML. JSON is the standard for Azure Resource Manager.

B. YAML

Although YAML is used in Azure Bicep and some DevOps pipelines, ARM templates specifically use JSON.

D. HTML

HTML is used for web page structure and presentation, not for defining infrastructure in Azure.

E. CSV

CSV is used for tabular data, not for complex infrastructure definitions or configurations.

Correct Answer

A. Establish a connection to Azure Key Vault, instantiate CertificatePolicy, set key properties, and create the certificate.

Explanation

To correctly apply a CertificatePolicy when creating a self-signed certificate in Azure Key Vault, you should first establish a connection to Azure Key Vault. Then, instantiate the CertificatePolicy and set the required key properties. Finally, create the certificate using the defined policy. The sequence ensures that the policy is set before the certificate is created, applying the necessary configurations for key properties like key type, key size, validity, etc.

Why other options are wrong

B. Instantiate CertificatePolicy, establish a connection to Azure Key Vault, create the certificate, and then set key properties.

This sequence is incorrect because key properties should be defined in the CertificatePolicy before creating the certificate to ensure proper policy application.

C. Create the certificate, establish a connection to Azure Key Vault, instantiate CertificatePolicy, and then set key properties.

Creating the certificate before applying the CertificatePolicy is incorrect. The policy needs to be defined first before creating the certificate to ensure the correct settings are applied.

D. Establish a connection to Azure Key Vault, create the certificate, instantiate CertificatePolicy, and then set key properties.

The correct sequence is to instantiate the CertificatePolicy and set the properties before creating the certificate, ensuring that the policy is applied properly.

Correct Answer

A. Microsoft.Compute

Explanation

Microsoft.Compute is the resource provider used in an Azure Resource Manager (ARM) template to deploy virtual machines. This resource provider handles the creation and management of compute resources, including virtual machines, virtual machine scale sets, and other computer-related services.

Why other options are wrong

B. Microsoft.Network

Microsoft.Network is the resource provider used to deploy and manage networking resources in Azure, such as virtual networks, subnets, load balancers, and network security groups. It is not used to deploy virtual machines.

C. Microsoft.Storage

Microsoft.Storage is the resource provider used for managing storage resources in Azure, such as storage accounts, blobs, queues, and files. While virtual machines use storage resources, the virtual machine itself is deployed via Microsoft.Compute.

D. Microsoft.Web

Microsoft.Web is the resource provider used for managing web applications, web apps, and app services in Azure. It is not responsible for deploying virtual machines.

Correct Answer

C. They ensure that both accounts have the necessary permissions to access the blobs.

Explanation

When copying a blob between two storage accounts with public access disabled, Shared Access Signatures (SAS) tokens are required for both the source and destination blob URLs. SAS tokens provide the necessary permissions to access the blobs in each storage account, even if the accounts have public access disabled. The SAS tokens enable secure, controlled access to the resources without exposing the storage account keys. Without SAS tokens for both source and destination, the copy operation would fail due to insufficient permissions.

Why other options are wrong

A. They authenticate the user for both accounts.

SAS tokens do not authenticate the user. Instead, they provide temporary, delegated access to specific resources in the storage account. Authentication typically happens through other mechanisms, like Azure Active Directory (AAD).

B. They allow the copying process to be initiated from either account.

While SAS tokens are required for both the source and destination accounts, they do not specifically allow the copy process to be initiated from either account. The copy process requires permission on both ends, but the token itself is not responsible for the initiation.

D. They are only needed for the source account.

SAS tokens are needed for both the source and destination accounts to ensure proper permissions for both locations during the copying process. Without a token for the destination account, the operation would not be authorized, even if the source account is authorized.

Correct Answer

D. must be rehydrated before the data can be accessed.

Explanation

Data stored in the Archive tier is optimized for long-term storage and is not immediately available for access. To read or modify this data, it must first be rehydrated—that is, moved to either the Hot or Cool access tier. This rehydration process can take several hours depending on the file size and workload.

Why other options are wrong

A. can be accessed at any time by using azcopy.exe

AzCopy is a tool for data transfer, but it cannot bypass the Archive tier's limitation. Data in the Archive tier is not immediately accessible by any tool until it is rehydrated.

B. can only be read by using Azure Backup

Azure Backup is a separate service and not a requirement for accessing data in the Archive tier. It does not unlock archive data access.

C. must be restored before the data can be accessed

“Restored” is a vague term in this context. The correct terminology is rehydrated, which is specific to Azure Storage access tiers and better describes the required process.

Correct Answer

A. In Azure AD, create a new conditional access policy.

D. In Azure AD conditional access, enable the baseline policy.

E. Upgrade to Azure AD Premium.

Explanation

To implement multifactor authentication (MFA) for your internal website using Azure AD, you would start by creating a conditional access policy in Azure AD to enforce MFA for your users. This is done through Azure AD's conditional access settings. Enabling the baseline policy for MFA also ensures a minimum level of security for all users. Additionally, upgrading to Azure AD Premium is necessary as it provides the full functionality for configuring conditional access policies and managing MFA.

Why other options are wrong

B. In Azure AD, enable application proxy.

Enabling an application proxy in Azure AD is used for exposing on-premises applications to the cloud, not for enabling MFA. While it is useful for hybrid environments, it does not directly implement MFA.

C. Configure the website to use Azure AD B2C.

Azure AD B2C is designed for customer-facing applications, providing authentication and authorization for external users. It is not required or ideal for implementing MFA for an internal website where employees are the users.

Correct Answer

B. It allows the function to handle HTTP requests directly without additional bindings.

Explanation

The enableForwardingHttpRequest setting in Azure Functions is used to control whether the incoming HTTP request is forwarded to the function's execution context. This setting is important for webhook-triggered functions because it allows the function to handle HTTP requests directly. When this setting is enabled, the HTTP request is passed to the function without needing additional bindings for HTTP trigger input. This is particularly useful when you need the function to respond directly to HTTP requests, for example, in scenarios involving webhooks.

Why other options are wrong

A. It specifies the path to the executable for the function.

This is not the purpose of the enableForwardingHttpRequest setting. The path to an executable is usually specified in other configuration settings but not related to this specific setting in Azure Functions.

C. It defines the working directory for the function execution.

The working directory is typically specified by other settings or default configurations in Azure Functions, but enableForwardingHttpRequest does not define or affect the function’s working directory.

D. It sets the arguments for the function execution.

The enableForwardingHttpRequest setting does not define arguments for the function. It is specifically concerned with whether the HTTP request is forwarded to the function itself, not with setting execution arguments.

Correct Answer

B. Management Groups

Explanation

The highest scope in Azure for applying Role-Based Access Control (RBAC) is Management Groups. Management groups are used to organize subscriptions, and roles assigned at this level can be inherited by all subscriptions within the management group. It serves as the top-most scope for applying access control policies.

Why other options are wrong

A. Subscription

While subscriptions are a high-level scope for managing resources, they are under management groups in the hierarchy, meaning management groups are the parent scope.

C. Resource Groups

Resource groups are lower in the scope hierarchy, beneath subscriptions, and are used to organize related Azure resources.

D. Resources

Resources represent the individual services or components within Azure (like virtual machines or storage accounts), and they are at the lowest level in the RBAC hierarchy. They are not the top-most scope.

Correct Answer

D. TFTP

Explanation

TFTP (Trivial File Transfer Protocol) is not supported for uploading code to an Azure App Service web app. Azure App Service supports FTP, FTPS, and SFTP for uploading web application code, but TFTP is not supported because it lacks the security features necessary for secure file transfer in cloud environments.

Why other options are wrong

A. FTP

FTP (File Transfer Protocol) is supported by Azure App Service for uploading code, though it is less secure than FTPS or SFTP.

B. FTPS

FTPS (FTP Secure) is supported and is a secure version of FTP that uses SSL/TLS to encrypt the connection. It is a common method for securely uploading files to Azure App Service.

C. SFTP

SFTP (Secure File Transfer Protocol) is also supported by Azure App Service. It is a secure alternative to FTP and FTPS, using SSH to encrypt the connection.
