• Question 163:

  You are developing a Microsoft Bot Framework application. The application consumes structured NoSQL data that must be stored in the cloud.

  You implement Azure Blob storage for the application. You want access to the blob store to be controlled by using a role.

  You implement Shared Access Signatures (SAS) on the storage account.

  Does this action accomplish your objective?

  A. Yes, it does

  B. No, it does not

  Correct Answer: B

  Implementing Shared Access Signatures (SAS) on the storage account can help accomplish your objective of controlling access to the blob store based on a role.

  By using SAS, you can generate a token that includes specific permissions and a limited validity period. This token can be issued to users or clients with the required role. The role determines the permissions they have on the blob store. The SAS token can be attached to a request made to the storage account, granting temporary access to perform specific operations, such as read or write, on the blob store.

  With SAS, you have fine-grained control over who can access the blob store and what operations they can perform. By generating SAS tokens with different permissions for different roles, you can enforce access control based on the desired roles within your application.

• Question 164:

  You are developing a Microsoft Bot Framework application. The application consumes structured NoSQL data that must be stored in the cloud.

  You implement Azure Blob storage for the application. You want access to the blob store to be controlled by using a role.

  You implement Shared Key authorization on the storage account.

  Does this action accomplish your objective?

  A. Yes, it does

  B. No, it does not

  Correct Answer: B

  Shared Key authorization is not suitable for controlling access to the blob store based on roles. Shared Key authorization provides a storage account access key, which can be used to authenticate and access the blob store. However, it does not support role-based access control (RBAC) or fine-grained access control.

  To control access to the blob store based on roles, you should use Azure Blob storage with Azure Active Directory (Azure AD) integration. Azure AD enables you to define roles and assign them to users or groups, allowing you to manage access control at a more granular level. With Azure AD integration, you can use RBAC to control who can perform specific actions on the blob store, such as read, write, or delete.

  By combining Azure Blob storage with Azure AD integration and RBAC, you can achieve the objective of controlling access to the blob store based on roles.

• Question 165:

  You are developing a Microsoft Bot Framework application. The application consumes structured NoSQL data that must be stored in the cloud.

  You implement Azure Blob storage for the application. You want access to the blob store to be controlled by using a role.

  You implement On-premises Active Directory Domain Services (AD DS).

  Does this action accomplish your objective?

  A. Yes, it does

  B. No, it does not

  Correct Answer: B

  Implementing On-premises Active Directory Domain Services (AD DS) alone does not accomplish the objective of controlling access to Azure Blob storage based on a role.

  On-premises AD DS is designed for managing user accounts, groups, and authentication within an on-premises network. It does not directly integrate with Azure Blob storage to control access based on roles.

  To achieve role-based access control (RBAC) for Azure Blob storage, you should consider integrating Azure Active Directory (Azure AD) with your application. Azure AD provides a cloud-based identity and access management solution that can be used to define roles, assign permissions, and control access to Azure resources, including Blob storage.

  By implementing Azure AD integration, you can manage access to Blob storage based on roles defined in Azure AD, granting or restricting access to users or groups based on their assigned roles.
