You are designing an Azure Synapse Analytics workspace.
You need to recommend a solution to provide double encryption of all the data at rest.

Which two components should you include in the recommendation? Each correct answer presents part of the solution.

NOTE: Each correct selection is worth one point.

  1. an X.509 certificate
  2. an RSA key
  3. an Azure virtual network that has a network security group (NSG)
  4. an Azure Policy initiative
  5. an Azure key vault that has purge protection enabled

Answer(s): B,E

Explanation:

Synapse workspaces encryption uses existing keys or new keys generated in Azure Key Vault. A single key is used to encrypt all the data in a workspace. Synapse workspaces support RSA 2048 and 3072 byte-sized keys, and RSA-HSM keys.

The Key Vault itself needs to have purge protection enabled.

You have an Azure Synapse Analytics serverless SQL pool named Pool1 and an Azure Data Lake Storage Gen2 account named storage1. The AllowBlobPublicAccess property is disabled for storage1.

You need to create an external data source that can be used by Azure Active Directory (Azure AD) users to access storage from Pool1.

What should you create first?

  1. an external resource pool
  2. an external library
  3. database scoped credentials
  4. a remote service binding

Answer(s): C

Explanation:

Security
User must have SELECT permission on an external table to read the data. External tables access underlying Azure storage using the database scoped credential defined in data source.

Note: A database scoped credential is a record that contains the authentication information that is required to connect to a resource outside SQL Server. Most credentials include a Windows user and password.

You have an Azure Data Factory pipeline named Pipeline1. Pipeline1 contains a copy activity that sends data to an Azure Data Lake Storage Gen2 account. Pipeline1 is executed by a schedule trigger.

You change the copy activity sink to a new storage account and merge the changes into the collaboration branch.

After Pipeline1 executes, you discover that data is NOT copied to the new storage account.
You need to ensure that the data is copied to the new storage account.

What should you do?

  1. Publish from the collaboration branch.
  2. Create a pull request.
  3. Modify the schedule trigger.
  4. Configure the change feed of the new storage account.

Answer(s): A

Explanation:

CI/CD lifecycle
1. A development data factory is created and configured with Azure Repos Git. All developers should have permission to author Data Factory resources like pipelines and datasets.
2. A developer creates a feature branch to make a change. They debug their pipeline runs with their most recent changes
3. After a developer is satisfied with their changes, they create a pull request from their feature branch to the main or collaboration branch to get their changes reviewed by peers.
4. After a pull request is approved and changes are merged in the main branch, the changes get published to the development factory.

You have an Azure Data Factory pipeline named pipeline1 that is invoked by a tumbling window trigger named Trigger1. Trigger1 has a recurrence of 60 minutes.

You need to ensure that pipeline1 will execute only if the previous execution completes successfully.

How should you configure the self-dependency for Trigger1?

  1. offset: "-00:01:00" size: "00:01:00"
  2. offset: "01:00:00" size: "-01:00:00"
  3. offset: "01:00:00" size: "01:00:00"
  4. offset: "-01:00:00" size: "01:00:00"

Answer(s): D

Explanation:

Tumbling window self-dependency properties
In scenarios where the trigger shouldn't proceed to the next window until the preceding window is successfully completed, build a self-dependency. A self-dependency trigger that's dependent on the success of earlier runs of itself within the preceding hour will have the properties indicated in the following code.

Example code:

"name": "DemoSelfDependency",
"properties": {
"runtimeState": "Started",
"pipeline": {
"pipelineReference": {
"referenceName": "Demo",
"type": "PipelineReference"
}
},
"type": "TumblingWindowTrigger",
"typeProperties": {
"frequency": "Hour",
"interval": 1,
"startTime": "2018-10-04T00:00:00Z",
"delay": "00:01:00",
"maxConcurrency": 50,
"retryPolicy": {
"intervalInSeconds": 30
},
"dependsOn": [
{
"type": "SelfDependencyTumblingWindowTriggerReference",
"size": "01:00:00",
"offset": "-01:00:00"
}
]
}
}
}
