Question 1:
You have an Azure data factory named ADF1.
You currently publish all pipeline authoring changes directly to ADF1.
You need to implement version control for the changes made to pipeline artifacts. The solution must ensure that you can apply version control to the resources currently defined in the UX Authoring canvas for ADF1.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
A. From the UX Authoring canvas, select Set up code repository.
B. Create a Git repository.
C. Create a GitHub action.
D. Create an Azure Data Factory trigger.
E. From the UX Authoring canvas, select Publish.
F. From the UX Authoring canvas, run Publish All.
Correct Answer: AB
To implement version control for changes made to pipeline artifacts in ADF1 while ensuring that version control can be applied to the resources currently defined in the UX Authoring canvas, you should perform the following two actions:
A. From the UX Authoring canvas, select Set up code repository: This will allow you to configure ADF1 to integrate with a version control system such as Git, which will enable you to track changes made to pipeline artifacts over time.
B. Create a Git repository: This will provide the version control system needed to track changes made to pipeline artifacts in ADF1.
Therefore, options A and B are the correct answers.
C, D, E, and F are not relevant to implementing version control for changes made to pipeline artifacts in ADF1.
Question 2:
You have an Azure Data Lake Storage Gen2 account named account1 that contains a container named container1.
You plan to create lifecycle management policy rules for container1.
You need to ensure that you can create rules that will move blobs between access tiers based on when each blob was accessed last.
What should you do first?
A. Configure object replication
B. Create an Azure application
C. Enable access time tracking
D. Enable the hierarchical namespace
Correct Answer: C
Generally available: Access time-based lifecycle management rules for Data Lake Storage Gen2
Some data in Azure Storage is written once and read many times. To effectively manage the lifecycle of such data and optimize your storage costs, it is important to know the last time of access for the data. When access time tracking is
enabled for a storage account, the last access time property on the file is updated when it is read. You can then define lifecycle management policies based on last access time:
Transition objects from hotter to cooler access tiers if the file has not been accessed for a specified duration.
Automatically transition objects from cooler to hotter access tiers when a file is accessed again.
Delete objects if they have not been accessed for an extended duration.
Access time tracking is only available for files in Data Lake Storage Gen2.
Reference:
https://azure.microsoft.com/en-us/updates/access-time-based-lifecycle-management-adls-gen2
Question 3:
You have the following Azure Data Factory pipelines:
1.Ingest Data from System1
2.Ingest Data from System2
3.Populate Dimensions
4.Populate Facts
Ingest Data from System1 and Ingest Data from System2 have no dependencies. Populate Dimensions must execute after Ingest Data from System1 and Ingest Data from System2. Populate Facts must execute after the Populate Dimensions pipeline. All the pipelines must be executed every eight hours.
What should you do to schedule the pipelines for execution?
A. Add an event trigger to all four pipelines.
B. Add a schedule trigger to all four pipelines.
C. Create a patient pipeline that contains the four pipelines and use a schedule trigger.
D. Create a patient pipeline that contains the four pipelines and use an event trigger.
Correct Answer: C
Schedule trigger: A trigger that invokes a pipeline on a wall-clock schedule.
Reference: https://docs.microsoft.com/en-us/azure/data-factory/concepts-pipeline-execution-triggers
Question 4:
You are designing an Azure Stream Analytics solution that will analyze Twitter data.
You need to count the tweets in each 10-second window. The solution must ensure that each tweet is counted only once.
Solution: You use a hopping window that uses a hop size of 5 seconds and a window size 10 seconds.
Does this meet the goal?
A. Yes
B. No
Correct Answer: B
Instead, use a tumbling window. Tumbling windows are a series of fixed-sized, non-overlapping, and contiguous time intervals.
Reference: https://docs.microsoft.com/en-us/stream-analytics-query/tumbling-window-azure-stream-analytics
Question 5:
You need to integrate the on-premises data sources and Azure Synapse Analytics. The solution must meet the data integration requirements. Which type of integration runtime should you use?
A. Azure-SSIS integration runtime
B. self-hosted integration runtime
C. Azure integration runtime
Correct Answer: C
Question 6:
You are designing an Azure Databricks interactive cluster. The cluster will be used infrequently and will be configured for auto-termination. You need to use that the cluster configuration is retained indefinitely after the cluster is terminated. The solution must minimize costs. What should you do?
A. Pin the cluster.
B. Create an Azure runbook that starts the cluster every 90 days.
C. Terminate the cluster manually when processing completes.
D. Clone the cluster after it is terminated.
Correct Answer: A
Azure Databricks retains cluster configuration information for up to 70 all-purpose clusters terminated in the last 30 days and up to 30 job clusters recently terminated by the job scheduler. To keep an all-purpose cluster configuration even after it has been terminated for more than 30 days, an administrator can pin a cluster to the cluster list.
Reference: https://docs.microsoft.com/en-us/azure/databricks/clusters/
Question 7:
You use Azure Stream Analytics to receive Twitter data from Azure Event Hubs and to output the data to an Azure Blob storage account.
You need to output the count of tweets from the last five minutes every minute.
Which windowing function should you use?
A. Sliding
B. Session
C. Tumbling
D. Hopping
Correct Answer: D
Hopping window functions hop forward in time by a fixed period. It may be easy to think of them as Tumbling windows that can overlap and be emitted more often than the window size. Events can belong to more than one Hopping window result set. To make a Hopping window the same as a Tumbling window, specify the hop size to be the same as the window size.
Reference: https://docs.microsoft.com/en-us/azure/stream-analytics/stream-analytics-window-functions
Question 8:
HOTSPOT
You plan to develop a dataset named Purchases by using Azure Databricks. Purchases will contain the following columns:

Question 10:
You plan to create an Azure Databricks workspace that has a tiered structure. The workspace will contain the following three workloads:
1. A workload for data engineers who will use Python and SQL.
2. A workload for jobs that will run notebooks that use Python, Scala, and SOL.
3. A workload that data scientists will use to perform ad hoc analysis in Scala and R.
The enterprise architecture team at your company identifies the following standards for Databricks environments:
1. The data engineers must share a cluster.
2. The job cluster will be managed by using a request process whereby data scientists and data engineers provide packaged notebooks for deployment to the cluster.
3. All the data scientists must be assigned their cluster that terminates automatically after 120 minutes of inactivity. Currently, there are three data scientists.
You need to create the Databricks clusters for the workloads.
Solution: You create a Standard cluster for each data scientist, a high-concurrency cluster for the data engineers, and a High Concurrency cluster for the jobs.
Does this meet the goal?
A. Yes
B. No
Correct Answer: A
We need a High Concurrency cluster for the data engineers and the jobs.
Note:
Standard clusters are recommended for a single user. Standard can run workloads developed in any language: Python, R, Scala, and SQL.
A high-concurrency cluster is a managed cloud resource. The key benefits of high concurrency clusters are that they provide Apache Spark-native fine-grained sharing for maximum resource utilization and minimum query latencies.

Question 11:
DRAG DROP
You are designing an Azure Data Lake Storage Gen2 structure for telemetry data from 25 million devices distributed across seven key geographical regions. Each minute, the devices will send a JSON payload of metrics to Azure Event Hubs.
You need to recommend a folder structure for the data. The solution must meet the following requirements:
1. Data engineers from each region must be able to build their pipelines for the data of their respective regions only.
2. The data must be processed at least once every 15 minutes for inclusion in Azure Synapse Analytics serverless SQL pools.
How should you recommend completing the structure? To answer, drag the appropriate values to the correct targets. Each value may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
Select and Place:
Correct Answer:
Box 1: {regionID}/raw
Data engineers from each region must be able to build their pipelines for the data of their respective regions only.

How should you complete the T-SQL command? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:
Correct Answer:
Range Left or Right, both create similar partition but there is a difference in comparison
For example: in this scenario, when you use LEFT and 20100101,20110101,20120101 Partition will be, datecol<=20100101, datecol>20100101 and datecol<=20110101, datecol>20110101 and datecol<=20120101, datecol>20120101 But if you use range RIGHT and 20100101,20110101,20120101
The partition will be, datecol<20100101, datecol>=20100101 and datecol<20110101, datecol>=20110101 and datecol<20120101, datecol>=20120101 In this example, Range RIGHT will be suitable for calendar comparison Jan 1st to Dec 31st Reference:
Question 14:
You create an Azure Databricks cluster and specify an additional library to install.
When you attempt to load the library to a notebook, the library in not found.
You need to identify the cause of the issue.
What should you review?
A. notebook logs
B. cluster event logs
C. global init scripts logs
D. workspace logs
Correct Answer: C
Cluster-scoped Init Scripts: Init scripts are shell scripts that run during the startup of each cluster node before the Spark driver or worker JVM starts. Databricks customers use init scripts for various purposes such as installing custom libraries, launching background processes, or applying enterprise security policies.
Logs for Cluster-scoped init scripts are now more consistent with Cluster Log Delivery and can be found in the same root folder as driver and executor logs for the cluster.
Reference: https://databricks.com/blog/2018/08/30/introducing-cluster-scoped-init-scripts.html
Question 15:
You have an Azure Data Factory pipeline that is triggered hourly.
