The Auto-Remediation feature in Azure Security Center automates the application of security controls, enhancing the security posture across different Azure services.

Explain how Azure Storage Service Encryption (SSE) enhances data security.

  • SSE encrypts data at rest
  • SSE encrypts data during processing
  • SSE encrypts data in memory
  • SSE encrypts data in transit
Azure Storage Service Encryption (SSE) enhances data security by encrypting data at rest, ensuring that even if unauthorized access occurs, the data remains protected.

Explain how Azure Synapse Analytics integrates with other Azure services for advanced analytics.

  • Azure Databricks
  • Azure Logic Apps
  • Azure Machine Learning
  • Azure Synapse Studio
Azure Synapse Analytics seamlessly integrates with Azure Synapse Studio, Azure Machine Learning, Azure Databricks, and Azure Logic Apps to enable advanced analytics and streamline data processing workflows.

Data binding in DataGrid and DataGridView controls helps in synchronizing data between the control and the ___________.

  • DataAdapter
  • DataSet
  • DataSource
  • DataTable
Data binding in DataGrid and DataGridView controls helps in synchronizing data between the control and the DataSource, which represents the data source for the control.

In LINQ to Entities, what is the purpose of the ObjectContext class?

  • Facilitates the mapping between the conceptual model and the storage model.
  • Manages database connections, transactions, and objects in an entity data model.
  • Provides methods for querying and manipulating entity data.
  • Represents a set of entities that are tracked for changes.
The ObjectContext class in LINQ to Entities acts as a bridge between the conceptual model (objects) and the storage model (database), managing connections, transactions, and object state tracking.

The ExecuteReader method returns a ___________ object that can be used to read the result set.

  • DataAdapter
  • DataReader
  • DataSet
  • DataView
In .NET, the ExecuteReader method is used to execute a SQL query and retrieve data from a database. It returns a DataReader object, which provides a forward-only, read-only stream of data from the database. The DataReader is efficient for processing large result sets sequentially.

In LINQ to DataSet, the group by clause is used to group data based on ___________ columns.

  • Common
  • Identical
  • Related
  • Similar
The group by clause in LINQ to DataSet is used to group data based on related columns. It allows you to organize your data into groups based on a specified column or columns, facilitating easier analysis and processing of grouped data.

How can you improve the performance of Entity Framework queries when dealing with large datasets?

  • By avoiding eager loading
  • By disabling lazy loading
  • By increasing database server memory
  • By using pagination
Disabling lazy loading can improve the performance of Entity Framework queries when dealing with large datasets. Lazy loading is the default behavior in Entity Framework, where related entities are loaded from the database only when they are accessed for the first time. This can lead to numerous database round-trips when dealing with large datasets, resulting in poor performance. By disabling lazy loading, all related entities are eagerly loaded along with the main entity, reducing the number of database round-trips and improving query performance. However, it's essential to consider the trade-offs, such as increased memory usage, when disabling lazy loading.

In ADO.NET, the Savepoint feature is used for ___________ within a transaction.

  • Atomicity
  • Consistency
  • Durability
  • Partial rollback
In ADO.NET, the Savepoint feature is used for partial rollback within a transaction, allowing specific parts of the transaction to be undone while preserving the rest.

The ___________ data provider is used for connecting to Oracle databases in ADO.NET.

  • OracleClient
  • OLEDB
  • SQLClient
  • DB2Client
The correct option is OracleClient. OracleClient is the specific ADO.NET data provider used for connecting to Oracle databases. It offers optimized performance and features tailored for Oracle databases. Using a database-specific data provider ensures better compatibility and performance compared to generic providers like SQLClient or OLEDB when working with a particular database management system.

When binding data to a DropDownList, you typically set the ___________ property to the data field that will be displayed to the user.

  • Display
  • Field
  • Text
  • Value
The correct answer is "Text." When binding data to a DropDownList, you typically set the DataTextField property to the name of the data field that will be displayed to the user. This field represents the text that the user sees in the DropDownList for each item.

Data binding in WPF supports ___________ and ___________ data binding modes.

  • OneTime
  • OneToN
  • OneWay
  • TwoWay
WPF data binding supports both OneWay and TwoWay binding modes. OneWay binding updates the target property when the source property changes, while TwoWay binding allows changes in either the source or target to update the other. These modes provide flexibility in synchronizing data between UI elements and underlying data sources.
