NEW QUESTION 82
You build an Azure Data Factory pipeline to move data from an Azure Data Lake Storage Gen2 container to a database in an Azure Synapse Analytics dedicated SQL pool.
Data in the container is stored in the following folder structure.
/in/{YYYY}/{MM}/{DD}/{HH}/{mm}
The earliest folder is /in/2021/01/01/00/00. The latest folder is /in/2021/01/15/01/45.
You need to configure a pipeline trigger to meet the following requirements:
* Existing data must be loaded.
* Data must be loaded every 30 minutes.
* Late-arriving data of up to two minutes must he included in the load for the time at which the data should have arrived.
How should you configure the pipeline trigger? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation
Box 1: Tumbling window
To be able to use the Delay parameter we select Tumbling window.
Box 2:
Recurrence: 30 minutes, not 32 minutes
Delay: 2 minutes.
The amount of time to delay the start of data processing for the window. The pipeline run is started after the expected execution time plus the amount of delay. The delay defines how long the trigger waits past the due time before triggering a new run. The delay doesn't alter the window startTime.

NEW QUESTION 84
You plan to ingest streaming social media data by using Azure Stream Analytics. The data will be stored in files in Azure Data Lake Storage, and then consumed by using Azure Datiabricks and PolyBase in Azure Synapse Analytics.
You need to recommend a Stream Analytics data output format to ensure that the queries from Databricks and PolyBase against the files encounter the fewest possible errors. The solution must ensure that the tiles can be queried quickly and that the data type information is retained.
What should you recommend?
- A. CSV
- B. JSON
- C. Avro
- D. Parquet
Answer: C
Explanation:
Explanation
The Avro format is great for data and message preservation.Avro schema with its support for evolution is essential for making the data robust for streaming architectures like Kafka, and with the metadata that schema provides, you can reason on the data. Having a schema provides robustness in providing meta-data about the data stored in Avro records which are self- documenting the data.References:http://cl oudurable.com/blog/avro/index.html
NEW QUESTION 85
You have an Azure data factory.
You need to examine the pipeline failures from the last 180 flays.
What should you use?
- A. Pipeline runs in the Azure Data Factory user experience
- B. Azure Data Factory activity runs in Azure Monitor
- C. the Activity tog blade for the Data Factory resource
- D. the Resource health blade for the Data Factory resource
Answer: B
Explanation:
Explanation
Data Factory stores pipeline-run data for only 45 days. Use Azure Monitor if you want to keep that data for a longer time.

NEW QUESTION 86
You have two fact tables named Flight and Weather. Queries targeting the tables will be based on the join between the following columns.
You need to recommend a solution that maximizes query performance.
What should you include in the recommendation?
- A. In each table, create an identity column.
- B. In the tables use a hash distribution of ArrivaIAirportID and AirportlD.
- C. In each table, create a column as a composite of the other two columns in the table.
- D. In the tables use a hash distribution of ArrivalDateTime and ReportDateTime.
Answer: B
Explanation:
Hash-distribution improves query performance on large fact tables.
Incorrect Answers:
A: Do not use a date column for hash distribution. All data for the same date lands in the same distribution. If several users are all filtering on the same date, then only 1 of the 60 distributions do all the processing work.
NEW QUESTION 87
Which Azure Data Factory components should you recommend using together to import the daily inventory data from the SQL server to Azure Data Lake Storage? To answer, select the appropriate options in the answer area.

NEW QUESTION 88
You are designing a date dimension table in an Azure Synapse Analytics dedicated SQL pool. The date dimension table will be used by all the fact tables.
Which distribution type should you recommend to minimize data movement?
- A. ROUND ROBIN
- B. HASH
- C. REPLICATE
Answer: C
Explanation:
A replicated table has a full copy of the table available on every Compute node. Queries run fast on replicated tables since joins on replicated tables don't require data movement. Replication requires extra storage, though, and isn't practical for large tables.

You need to schedule an Azure Data Factory pipeline to execute when a new file arrives in an Azure Data Lake Storage Gen2 container.
Which type of trigger should you use?
- A. on-demand
- B. schedule
- C. event
- D. tumbling window
Answer: C
Explanation:
Event-driven architecture (EDA) is a common data integration pattern that involves production, detection, consumption, and reaction to events. Data integration scenarios often require Data Factory customers to trigger pipelines based on events happening in storage account, such as the arrival or deletion of a file in Azure Blob Storage account.

What are the best resources to use when studying for the exam, and what is the most cost-effective way to prepare?
The Microsoft Azure certification exams are pretty straightforward and easy to study for if you are using the right materials. There are a lot of companies out there that offer information about the exams, but not all of them can deliver what you need to pass. The key to passing any exam is having the right materials and the right study habits. You have probably heard this before, but the best way to study for an exam is to use real examples instead of just memorizing syntax or commands. If you can get your hands-on real projects that were developed on Azure, that's perfect; otherwise, a great resource is to use sample code designed specifically for studying for a particular certification exam. If you want to pass the DP-203 exam, then Microsoft DP-203 Dumps would help you prepare with a good understanding of each topic. Not only will this give you real examples and scenarios, but it will also allow you to focus on just the areas of Azure that are tested on the exam you are taking. In addition to using example-based code samples, you should also pay attention to how Microsoft designed its exams. Analytical strategy changing prep explanations flow policy slowly batch dimension retention. The questions aren't always easy, but they aren't exceptionally difficult either - they are usually based on the most common mistakes that people make when they first start using technology. Transactional flows proctored access user authentication.
