You are configuring a dataflow in Azure Data Factory. What does 'mapping data flow' allow you to do?
ATransform data in a graphical interface
BSchedule data pipelines easily
CSave all data to SQL databases
DSecure data with encryption at rest
Explanation
Mapping data flow allows for transformations visually, while B is incorrect because scheduling isn't the focus here, C relates to data storage, and D concerns data security.
Q92
A company needs to ensure that its Azure SQL Database remains available even during maintenance. Which feature should the company use?
AGeo-replication for databases
BAzure SQL Database auto-failover groups
CServerless mode for databases
DDynamic scalability features
Explanation
Auto-failover groups allow for high availability during maintenance, unlike A which is for disaster recovery, C is not related to maintenance, and D doesn't ensure availability.
Q93
What happens when you use Azure Synapse Analytics with dedicated SQL pool but forget to pause it after heavy usage?
AYour data will be deleted
BCosts will accrue based on usage
CThe service will automatically pause
DPerformance will degrade immediately
Explanation
Costs accrue since the dedicated SQL pool remains in use, while A is incorrect as data doesn't get deleted, C is incorrect because auto-pause is not default, and D is not accurate immediately.
Q94
Which service can automate data movement in Azure?
AAzure Data Factory
BAzure Blob Storage
CAzure DevOps
DAzure Functions
Explanation
Azure Data Factory is designed specifically for movement and transformation of data, unlike the other options that serve different purposes.
Q95
A company needs to store large amounts of unstructured data. Which Azure storage service is most suitable?
AAzure SQL Database
BAzure Cosmos DB
CAzure Blob Storage
DAzure Table Storage
Explanation
Azure Blob Storage is optimized for handling large unstructured data, while other options are suited for structured data or specific types.
Q96
What happens when you set a data flow to use an incorrect sink transformation schema in Azure Data Factory?
AData flow will abort
BData will be truncated
CTransformation will ignore schema
DData will be mapped differently
Explanation
Setting an incorrect schema is a critical error, causing the data flow to abort rather than performing any data manipulation.
Q97
Which service is primarily used for real-time analytics in Azure?
AAzure Stream Analytics
BAzure Blob Storage
CAzure Data Lake
DAzure Functions
Explanation
Azure Stream Analytics specializes in real-time data processing and analytics; the others do not focus on real-time analytics.
Q98
A company needs to store large amounts of unstructured data efficiently. Which Azure service should they use?
AAzure SQL Database
BAzure Cosmos DB
CAzure Blob Storage
DAzure Table Storage
Explanation
Azure Blob Storage is ideal for unstructured data storage; the others cater to structured or semi-structured data.
Q99
You are configuring a data pipeline in Azure Data Factory. What happens when you set up a failure action on a specific activity?
APipeline fails immediately
BAction triggers upon failure
CActivity retries indefinitely
DResults are discarded
Explanation
Setting a failure action allows you to define behavior when an activity fails; the other options misrepresent the outcome of a failure action.
Q100
Which service is best for building real-time analytics on streaming data?
AAzure Stream Analytics
BAzure Blob Storage
CAzure Data Lake
DAzure SQL Database
Explanation
Azure Stream Analytics specializes in real-time data processing while the others are for storage or database tasks.
