DP-203 Design and implement data security Practice Test 1 — 15 Questions

Question 1

A company uses Azure Synapse Analytics dedicated SQL pool. They need to ensure that only users with a specific Azure AD group can query a particular schema. Which approach should they use?

Accepted Answer

Use the GRANT statement to grant SELECT on the schema to the Azure AD group.. The GRANT statement in Azure Synapse dedicated SQL pool allows you to assign permissions directly to Azure AD groups. By granting SELECT on the schema to the specific Azure AD group, only members of that group can query objects within that schema, meeting the requirement precisely.

Answer

Configure a server-level firewall rule to block other users.

Answer

Create a row-level security policy on all tables in the schema.

Answer

Apply dynamic data masking to the schema.

Question 2

You are designing data security for Azure Data Lake Storage Gen2. The requirement is to prevent data from being accessed by anyone outside the corporate network. Which feature should you enable?

Accepted Answer

Use Azure Private Endpoint or service endpoint with a VNet.. Azure Private Endpoint or service endpoint with a VNet ensures that all traffic to the storage account stays within the corporate network and never traverses the public internet. Private Endpoint assigns a private IP from the VNet to the storage account, effectively isolating it from public access. This meets the requirement to prevent access from outside the corporate network by enforcing network-level isolation.

Answer

Assign RBAC roles to deny access to all except corporate users.

Answer

Configure IP firewall rules to allow only corporate IP ranges.

Answer

Enable encryption at rest using customer-managed keys.

Question 3

A company uses Azure Data Factory to copy sensitive data from on-premises SQL Server to Azure Blob Storage. They must ensure that data is encrypted in transit and at rest. Which combination of features should they use?

Accepted Answer

Configure the copy activity to use TLS and enable Azure Storage Service Encryption.. Option C is correct because Azure Data Factory's copy activity uses TLS (Transport Layer Security) to encrypt data in transit between the on-premises SQL Server and Azure Blob Storage, and Azure Storage Service Encryption (SSE) automatically encrypts data at rest using 256-bit AES encryption. This combination satisfies both encryption requirements without additional complexity.

Answer

Use Always Encrypted in SQL Server and customer-managed keys in Blob Storage.

Answer

Set up a VPN between on-premises and Azure, and use Azure Disk Encryption.

Answer

Use HTTPS for the copy activity and enable Azure Storage Service Encryption.

Question 4

You need to audit all data access to an Azure Storage account. Which Azure service should you enable?

Accepted Answer

Azure Storage analytics logs and send to Log Analytics workspace. Azure Storage analytics logs capture detailed information about successful and failed requests to a storage account, including authentication details, IP addresses, and operation types. By sending these logs to a Log Analytics workspace, you can query and analyze them using KQL, enabling comprehensive auditing of all data access. This is the correct service for auditing because it provides the granular, queryable logs required for security and compliance audits.

Answer

Azure Policy to audit storage account access

Answer

Azure Monitor metrics

Answer

Azure Security Center

Question 5

A company uses Azure Key Vault to store secrets for data pipelines. They need to rotate the secrets automatically every 90 days. What should they implement?

Accepted Answer

Configure Key Vault secret rotation with an expiration date of 90 days.. Option C is correct because Key Vault supports automatic rotation with a specified expiration period. Option A is wrong because manual rotation is not automatic. Option B is wrong because Azure Policy does not rotate secrets. Option D is wrong because RBAC controls access, not rotation.

Answer

Use Azure Policy to enforce secret expiration.

Answer

Assign RBAC roles to a service principal to update the secret.

Answer

Create a manual process to update the secret in Key Vault.

Question 6

Which TWO of the following are valid methods to secure data at rest in Azure Data Lake Storage Gen2?

Accepted Answer

Use customer-managed keys in Azure Key Vault. Option C is correct because using customer-managed keys (CMK) in Azure Key Vault allows you to control and rotate the encryption keys used for Azure Storage Service Encryption (SSE), providing an additional layer of security for data at rest. This is a valid method to secure data at rest in Azure Data Lake Storage Gen2, as it ensures that only authorized parties with access to the key vault can decrypt the data.

Answer

Assign RBAC roles for data access

Answer

Configure storage firewall rules

Answer

Enable TLS 1.2 for all connections

Question 7

Which THREE of the following are required to implement column-level security in Azure Synapse Analytics dedicated SQL pool?

Accepted Answer

A GRANT statement on specific columns to users or roles. Option A is correct because column-level security in Azure Synapse Analytics dedicated SQL pool is implemented using GRANT statements on specific columns. By granting SELECT on only certain columns to a user or role, you restrict access to sensitive data at the column level without needing to create views or modify schemas. This is the native mechanism provided by SQL Server and Azure Synapse for column-level security.

Answer

A VIEW that selects only the allowed columns

Answer

A DENY statement on specific columns to users or roles

Answer

A row-level security policy must be in place

Question 8

A company uses Azure Synapse Analytics with dedicated SQL pools. They need to allow a data scientist to read all tables in the 'sales' schema but prevent access to columns containing personally identifiable information (PII). Which feature should be used?

Accepted Answer

Column-level security. Column-level security (C) is the correct choice because it allows you to restrict access to specific columns in a table, such as PII columns, while granting read access to all other columns in the 'sales' schema. This is achieved by defining a GRANT SELECT statement on the table with a column list, or by using a security policy with a filter predicate that blocks access to sensitive columns. Unlike Dynamic Data Masking, which obfuscates data at query time but does not prevent the user from seeing the masked values in certain scenarios, Column-level security actually denies access to the specified columns entirely.

Answer

Dynamic data masking

Answer

Row-level security

Answer

Azure Active Directory authentication

Question 9

A company has an Azure Data Lake Storage Gen2 account. They want to ensure that only users with the 'Data Reader' role can access files in a specific container, while other users cannot list or read files. The storage account has hierarchical namespace enabled. What is the most secure and manageable approach?

Accepted Answer

Set POSIX-like access control lists (ACLs) on the container folder for the Data Reader role. Option D is correct because Azure Data Lake Storage Gen2 with hierarchical namespace enabled supports POSIX-like access control lists (ACLs) at the container and folder level. By setting ACLs on the specific container folder to grant 'Read' and 'Execute' permissions only to the 'Data Reader' role (or its associated security group), you enforce least-privilege access without affecting other containers. This approach is both secure and manageable, as ACLs are inherited by default and can be centrally managed via Azure RBAC integration.

Answer

Assign the Storage Blob Data Reader role at the storage account level and use row-level security

Answer

Generate a shared access signature (SAS) token for each user

Answer

Configure a storage firewall to allow only the Data Reader role's IP addresses

Question 10

You need to configure encryption for an Azure SQL Database to protect data at rest. Which Azure service or feature should you enable?

Accepted Answer

Transparent Data Encryption (TDE). Transparent Data Encryption (TDE) is the correct choice because it performs real-time I/O encryption and decryption of the data and log files at rest, protecting against unauthorized access to the physical storage media. TDE uses an AES-256 encryption algorithm and is fully transparent to the application, requiring no changes to the database schema or queries.

Answer

Dynamic Data Masking

Answer

Always Encrypted

Answer

Azure Information Protection

Question 11

A company is using Azure Data Factory to copy data from an on-premises SQL Server to Azure Blob Storage. The data must be encrypted in transit using TLS 1.2. The on-premises SQL Server is configured to support TLS 1.2. Which Data Factory property should be configured?

Accepted Answer

The typeProperties property in the linked service to include 'Encrypt=True' in the connection string. Option B is correct because TLS 1.2 encryption for data in transit between Azure Data Factory and an on-premises SQL Server is enforced by adding 'Encrypt=True' and 'TrustServerCertificate=False' to the connection string within the typeProperties of the linked service. This ensures the SQL Server Native Client uses TLS 1.2 for the connection, aligning with the requirement.

Answer

The encryptedCredential property in the linked service

Answer

The connectVia property in the linked service

Answer

The integrationRuntime property in the dataset

Question 12

You are designing a data solution in Azure that requires all data in transit between Azure Databricks and Azure Storage to be encrypted using a customer-managed key. Which configuration meets this requirement?

Accepted Answer

Enable 'Secure transfer required' on the storage account. Option A is correct because enabling 'Secure transfer required' on the storage account enforces HTTPS for all requests, which encrypts data in transit using TLS. This ensures that all traffic between Azure Databricks and Azure Storage is encrypted, and the encryption keys used for TLS are customer-managed when combined with a customer-managed key for the TLS session (though the question focuses on in-transit encryption, the key management for TLS itself is handled by the platform; the customer-managed key requirement is satisfied by using Azure Key Vault for the storage account's encryption key, but the in-transit encryption is enforced by HTTPS).

Answer

Configure a service endpoint and a firewall rule to restrict access to Azure Databricks

Answer

Create a customer-managed key in Azure Key Vault and assign it to the storage account for encryption

Answer

Set the minimum TLS version to 1.2 on the storage account

Question 13

Which TWO actions should you take to ensure that only authorized users can access sensitive data in an Azure Synapse Analytics dedicated SQL pool?

Accepted Answer

Implement row-level security. Row-level security (RLS) and column-level security are the two correct actions because they directly restrict data access at the row and column granularity within a dedicated SQL pool. RLS uses security predicates to filter which rows a user can query, while column-level security denies access to specific columns for unauthorized principals. Both are native features of Azure Synapse dedicated SQL pools that enforce authorization on the data plane.

Answer

Configure Azure Active Directory authentication

Answer

Enable dynamic data masking on all columns

Answer

Enable transparent data encryption

Question 14

Which THREE components are part of a defense-in-depth strategy for data security in Azure?

Accepted Answer

Network security groups (NSGs) on subnets. Network security groups (NSGs) are a fundamental component of a defense-in-depth strategy because they provide network-layer segmentation and filtering. By applying NSGs to subnets, you can control inbound and outbound traffic based on source/destination IP addresses, ports, and protocols, creating a perimeter defense that limits lateral movement in case of a breach.

Answer

Azure Policy to enforce tagging

Answer

Dynamic data masking for all databases

Question 15

Refer to the exhibit. A custom RBAC role is defined as shown. A user is assigned this role at the resource group scope. Which operation can the user perform?

Accepted Answer

List containers in a storage account within DataRG. The custom RBAC role includes the 'Microsoft.Storage/storageAccounts/blobServices/containers/read' action, which allows listing containers. Since the user is assigned this role at the resource group scope (DataRG), they can list containers in any storage account within that resource group. The role does not include any data plane actions (e.g., read/write/delete blob data) or container deletion permissions, so only the list operation is permitted.

Answer

Delete containers

Answer

Write blob data to containers

Answer

Read blob data from containers
