                                           scan from scanner to read article.

31)  which service should you use to extract text , key/Value pairs and table data automatically from scanned documents?

   a) Form recognizer 

   b) Text Analytics

   c) Language Understanding

   d) Custom vision

32 )You want to use computer vision service to identify the location of individual items in an image. Which of following feature should you retrieve ?

   a)object

   b)Tags

   c)Categories

34 ) You want use the computer vision service to analyse image and to use language service to analyse text.It is a must requirement that developer only use one key and endpoints to access all of your services, What kind recourses should you create in your azure subscription ?

   a)Computer vision

   b)Cognitive services

    c)Custom vision

35 )You use a azure Machine Learning designer pipeline to train and test a binary test a binary classification model.You review the model's performance metrics in an evaluate model module and note that it has AUC score of 0.3. what can you conclude about the model ?

   a)The model can explain 30% of variance between true and predicated labels.

   b) The model predicates accurately for 70% of test cases

  c) The model performs worse than random guessing.

Note :The ROC AUC score can range from 0 to 1.

A score of 0.5 indicates random guessing,

score of 1 indicates perfect performance.

A score slightly above 0.5 shows that a model has at least "some" (albeit small) predictive power. This is generally inadequate for any real applications.

above 0.8 is considered good,

score above 0.9 is considered great. 

36) You use Azure Machine Learning designer to create a training pipeline for classification model. What must you do before deploying the model as a service ? a) Create an interface pipeline from the training pipeline b) Add an Evaluate Model module to training pipeline c) Clone the training pipeline with a different name

37) You are using Azure Machine Learning designer to create training pipeline for binary classification model.you have added dataset contain feature and labels, a two class decision forest module and train module.you plan to use Score Model and Evaluate Model modules to test the trained model with subset of dataset that was not used for training. what is another module should you add ? a) join data b) Split data c) Select column in dataset

38)The ability to extract subtotal and total from receipt is a capability of the A)custom vision b)Form recognizer c)Ink Recognizer d) Test Analytics

39)You are building a tool that will process images from retail store and identify the products of competitors.The solution will use a custome model.which azure cognitive service should you use ? a)custom vision b)form recognizer c)face d)Computer vision

40)When you design an AI system to assess wheather lonas should be approved, ha factor used to make the decision should be explinable. This is an example of which Microsoft guiding principle for Repsponsible AI ? a)transparency b)inclusiveness c)Fairness d)Private an security
