• Question 77:

  You are building a bot on a local computer by using the Microsoft Bot Framework. The bot will use an existing Language Understanding model. You need to translate the Language Understanding model locally by using the Bot Framework CLI. What should you do first?

  A. From the Language Understanding portal, clone the model.

  B. Export the model as an .lu file.

  C. Create a new Speech service.

  D. Create a new Language Understanding service.

  Correct Answer: B

  You might want to manage the translation and localization for the language understanding content for your bot independently.

  Translate command in the @microsoft/bf-lu library takes advantage of the Microsoft text translation API to automatically machine translate .lu files to one or more than 60+ languages supported by the Microsoft text translation cognitive

  service.

  What is translated?

  An .lu file and optionally translate Comments in the lu file LU reference link texts

• Question 78:

  Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while

  others might not have a correct solution.

  After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.

  You have an Azure Cognitive Search service.

  During the past 12 months, query volume steadily increased.

  You discover that some search query requests to the Cognitive Search service are being throttled.

  You need to reduce the likelihood that search query requests are throttled.

  Solution: You migrate to a Cognitive Search service that uses a higher tier.

  Does this meet the goal?

  A. Yes

  B. No

  Correct Answer: A

  A simple fix to most throttling issues is to throw more resources at the search service (typically replicas for query-based throttling, or partitions for indexing-based throttling). However, increasing replicas or partitions adds cost, which is why it is important to know the reason why throttling is occurring at all.
