Test your knowledge of Dataverse Database

Explanation:

As you can create only one Dataverse database in a Power Platform environment, both the statements, ask the same question: Can you access Dataverse tables in a different environment from a flow/app?

Quick Preview:

Reference Link: https://docs.microsoft.com/en-us/power-platform/admin/create-database

Statement 1:

If you use the Dataverse connector (non-legacy), it always connects to the database in the current environment (where the flow runs). There is no option to select an environment.

But if you use the legacy Dataverse connector, it lets you choose Dataverse tables from a different environment within the tenant.

Reference Link: https://powerusers.microsoft.com/t5/Using-Connectors/Can-you-connect-to-more-than-one-Dataverse-environment-at-a-time/td-p/971643

https://docs.microsoft.com/en-us/connectors/commondataserviceforapps/

https://docs.microsoft.com/en-us/connectors/commondataservice/

We do not know till when Microsoft will support the legacy connector or if the option to connect to Dataverse tables in a different environment will be available in the non-legacy connector.

For now, though, statement 1 is correct.

Statement 2:

In addition to the tables in the current environment (where the app is created), you can change the environment to select Dataverse tables from a different environment.

This feature enables us to access tables in more than one Dataverse database (in different environments).

Reference Link: http://powerappsguide.com/blog/post/how-to-access-datavers-tables-from-another-environment

So, statement 2 is also correct.

Option Yes, Yes is the correct answer.

Test your knowledge of Custom Connectors

Explanation:

Many pre-built connectors may not expose everything an underlying API/service can perform. In case you need something offered by the API but unavailable in the connector, you can extend the Power Platform by creating a custom connector.

For the given scenario, I can query the Microsoft Graph API to get a list of all groups in my organization.

So, I can build a new custom connector and define an action ListGroups (using the request/response details from Graph Explorer).

In the below image, I am testing a connector to check if the ListGroups action retrieves the list of groups.

Finally, I use the List Groups action from the custom connector in a Power Automate flow.

Option 3 (Accepting your colleague’s recommendation) is the correct choice.

Reference Link: https://www.youtube.com/watch?v=b4aJdQrmTsQ&t=258s

Option 1 is incorrect since we learned that we can create a custom connector even if a standard connector is already available.

Option 2 is incorrect. You can suggest an idea to Microsoft, but since it is only for your project, it is easy and quick to develop a custom connector.

Option 4 is incorrect. You share a connector proposal on the GitHub repository if you want to certify a custom connector. We are not looking to certify the connector here.

Test your knowledge of AI Builder

Explanation:

The AI Builder custom category classification model analyzes unstructured text entries (tweets) and classifies/tags them.

To collect data, I created a Power Automate flow that triggers when a tweet with a hashtag (#muncheryjuice) is tweeted. Then, I store the twitter text in a Dataverse table.

For model training, I add tags for each tweet entry as either Ambience, Delivery, or Taste in the Dataverse table. I use this table for model (category classification) training.

Using the trained model, the model can apply tags to the incoming tweets. To tag text entries, the category classification model is the most suitable choice.

Reference Link: https://docs.microsoft.com/en-us/ai-builder/text-classification-overview

https://docs.microsoft.com/en-us/ai-builder/before-you-build-text-classification-model#data-preparation

Option 2 is the correct choice.

Option 1 is incorrect. Key phrase extraction, a prebuilt AI Builder model, extracts the main talking points in a given text. So, you cannot train and tag the data per your needs.

Reference Link: https://docs.microsoft.com/en-us/ai-builder/prebuilt-key-phrase

Option 3 is incorrect. Although category classification and entity extraction look similar, there is a difference. Entity extraction identifies/extracts keywords from text related to your business. And category classification buckets/classifies/tags the data into predefined categories.

For example, Munchery Juice tags tweets as either delivery or ambience with category classification. But use the entity extraction model to identify/extract Order Statuses like delivered, cancel, and delayed to classify them into the Order Status category.

Reference Link: https://docs.microsoft.com/en-us/ai-builder/entity-extraction-overview

Option 4 is incorrect. Sentiment analysis is a prebuilt model to detect the positive or negative sentiment in text data. We do not want to determine sentiment here.

Reference Link: https://docs.microsoft.com/en-us/ai-builder/prebuilt-sentiment-analysis

Test your knowledge of Power BI

Explanation:

Since the Sales tables contain a huge number of rows, and the report uses only a subset of the fields, we can create an aggregated table by using the Group by operation in Power Query.

The Group by operation outputs a record for each group (combination of category values) and aggregates the numeric values.

Select the category columns used in the report as group by columns (Product Color, Product Line, and Year) and click Group By

In the Group By window, we can view the selected columns as Group by columns. In addition, add the numeric fields to aggregate like Total Sales Amount, Order Quantity, and Average unit price.

Click OK and close the Power Query window. We get a trimmed-down model with only the required fields.

Option 1 is the correct choice.

Reference Link: https://docs.microsoft.com/en-us/power-bi/transform-model/aggregations-advanced

Option 2 is incorrect. Even if you remove unused columns, for each visual, a query is sent to the back end that aggregates more than a billion records in real-time, so visuals will still load slowly. Aggregation is a better performance optimization technique than removing columns.

Option 3 is incorrect. Changing the storage mode of the model to import will improve performance, as the queries are retrieved directly from the cache. But since the dataset is in a shared capacity, a table with a huge number of rows may not fit within the allocated memory size (1 GB).

Reference Link: https://docs.microsoft.com/en-us/power-bi/admin/service-admin-manage-your-data-storage-in-power-bi#dataset-limits

Option 4 is incorrect. By default, every visual on a report can interact with others. We can reduce the number of queries fired at the back end by turning off unnecessary interactions between them. But since there are only three visuals in the report, turning them off will not yield noticeable benefits.

Test your knowledge of Power Virtual Agents

Explanation:

Chatbots invoke Escalate topic for undefined issues on the third prompt. But, it’s not a good user experience for the customer to type the issue multiple times.

Since it is not possible to create topics for all kinds of user queries, enable the system fallback topic for the chatbot.

The fallback topic is a catchall topic. If a topic is undefined for any user query, the fallback topic is invoked. So, when the user types looking for dealerships, the chatbot triggers the fallback topic.

In the fallback topic, the user’s query is captured in the variable UnrecognizedTriggerPhrase. We can pass this variable as parameters to the Teams channel via flow.

The team members get notified about the in-demand topics and can plan to update the bot accordingly.

From the discussion above, a fallback topic is essential to capture undefined user intents. Option 4 is one of the correct answers.

In addition to that, since we need to display the message, Our agent will be in touch with you in the next 24 hours to the user, option 2 is the other correct answer.
