PL-400 Exam - Question 44


DRAG DROP -

An international organization has a series of client-server applications that manage red light cameras and traffic violations across a wide geographic region. The daily volume of traffic violations is very high and growing.

You plan to use Microsoft Power Platform apps to manage the following types of data:

✑ Existing vehicle licensing data must be imported into Microsoft Dataverse and easily queried.

✑ Red light camera images must be stored in a repository for later analysis.

✑ Information about traffic violations must be stored and related to vehicle details.

You need to select data storage mechanisms for the new apps.

Which data storage mechanisms should you use? To answer, drag the appropriate data storage mechanisms to the correct data types. Each storage mechanism 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.

Correct Answer:
Exam PL-400 Question 44

Box 1: Entity -

Existing vehicle licensing data must be imported into Microsoft Dataverse and easily queried.

Virtual tables (also known as virtual entities) enable the integration of data residing in external systems by seamlessly representing that data as tables in Microsoft

Dataverse, without replication of data and often without custom coding.

A virtual table is a definition of a table in the Dataverse platform without the associated physical tables for table instances created in the Dataverse database.

Instead during runtime, when a table instance is required, its state is dynamically retrieved from the associated external system.

The following data providers ship with Dataverse:

An OData v4 provider is included with the service and is installed by default. This provider supports create, read (retrieve, retrieve multiple), update and delete operations.

An Azure Cosmos DB -

Box 2: Azure Storage Blob -

Red light camera images must be stored in a repository for later analysis.

Use Azure Storage Blob for binary data.

Azure Blob storage stores massive amounts of unstructured object data, such as text or binary data.

Box 3: Azure Cosmos DB -

Information about traffic violations must be stored and related to vehicle details.

It should be Entity, Blob Entity

Entity(Since it says " Existing vehicle licensing data must be imported into Common Data Service and easily queried.") Azure Storage Blob - Designed to handle such objects Entity - Since it says "Information about traffic violations must be stored and related to vehicle details" Cosmos DB cannot be used because its noSQL

Correct Answer is Entity, Azure Storage Blob, Entity. Azure Cosmos DB it's a noSQL database, and it's not the best choice for images.

the answers are correct. "The daily volume of traffic violations is very high and growing." Azure Cosmos DB's design lets you scale to massive request volumes in the order of trillions of requests per day. https://learn.microsoft.com/en-us/azure/cosmos-db/use-cases

Well, looks like the answer for the 3rd option indeed can be Azure Cosmos DB. Because you can create a virtual entity using the Cosom DB data provider (https://learn.microsoft.com/en-us/power-apps/maker/data-platform/virtual-entity-documentdb-provider-requirements). So, based on clarification, that traffic volume is high and quickly grows, Cosmos DB looks like a good solution for this - because this is a NoSQL document DB and traffic info we can represent as a document. Based on the fact we should make the relationship, a virtual entity using the Cosmos DB data provider fits that condition, I believe, there should be Azure Cosmos DB.

at least as of nov. 2023, this features is till in preview, so I don't think the exam would base a correct answer on a feature that is not fully released, thus the third answer should be Entity

The question is tricky, since it says must to be imported, that means it is in another source, so probably the answer is correct. Cosmos DB Azure Blob Entity

the question ask the data storage option for new app so Cosmos DB can not be there

Entity, Blob, Entity - since indeed there's a requirement for relation between the vehicle licenses and violations.

Because Power apps can not retrieve more than 500 records(2000 max with configuration), I think with high volume of traffic violation, it can not correctly related with vehicle details.

1-Vehicle licensing data: Entity: Since vehicle licensing data will be imported into Dataverse and queried, it should be stored in a Dataverse entity, which is the preferred method for structured relational data within the Power Platform. 2-Red light camera photos: Azure Storage Blob: Images like red light camera photos should be stored in Azure Blob Storage because it is optimized for storing large, unstructured data like images, videos, or logs. 3-Information about traffic violations: Entity: Traffic violation information, which needs to be related to vehicle details, should be stored in a Dataverse entity. Entities are designed to store structured data and can be easily related to other entities. Correct matches: Vehicle licensing data → Entity Red light camera photos → Azure Storage Blob Information about traffic violations → Entity
