Question 120

A banking operations review examines Clustering in relation to the need to identify groups of shoppers when no segment labels have been provided. Which TWO statements are technically sound? (Choose TWO.)

  1. The main purpose of Clustering is to decide whether a submitted claim belongs to the suspicious or normal class instead of to identify groups of shoppers when no segment labels have been provided.
  2. Clustering organizes similar observations without using assigned target categories.
  3. The described method removes the need to consider the stated limitation because multiclass classification selects among several discrete mutually exclusive categories.
  4. Cluster interpretations must be validated and are not inherently ground truth.
  5. Clustering operates according to this purported mechanism: regression predicts a continuous numerical quantity based on known examples.

Explanation

Correct Answers

B:

This accurately identifies the operation behind Clustering: clustering organizes similar observations without using assigned target categories. It offers the mechanism needed to identify groups of shoppers when no segment labels have been provided in the banking operations example, with the boundary that cluster interpretations must be validated and are not inherently ground truth.

D:

This is a valid caution for Clustering: cluster interpretations must be validated and are not inherently ground truth. In a banking operations setting, the concern follows even when clustering organizes similar observations without using assigned target categories; it must be checked against the particular requirement to identify groups of shoppers when no segment labels have been provided.

Incorrect Answers

A:

The stated behavior is for Binary classification, not for Clustering in a banking operations requirement to identify groups of shoppers when no segment labels have been provided. A classifier maps input features to discrete labels or probabilities over classes is a real capability of the alternative, whereas the concept under review works because clustering organizes similar observations without using assigned target categories.

C:

This assertion incorrectly waives the limitation of Clustering in the banking operations context. The relevant boundary is that cluster interpretations must be validated and are not inherently ground truth; selecting a technology to identify groups of shoppers when no segment labels have been provided does not remove that underlying requirement.

E:

The stated behavior is for Regression, not for Clustering in a banking operations requirement to identify groups of shoppers when no segment labels have been provided. Regression predicts a continuous numerical quantity based on known examples is a real capability of the alternative, whereas the concept under review works because clustering organizes similar observations without using assigned target categories.

Question 121

For a financial operations use case that must extract printed text, tables and form fields from scanned invoices, the team is choosing between Amazon Textract and Amazon Rekognition. Which distinction is sound?

  1. Amazon Textract is chiefly intended to identify objects or unsafe visual content in uploaded photographs; Amazon Rekognition is chiefly intended to extract printed text, tables and form fields from scanned invoices.
  2. Amazon Textract supports the stated goal; Amazon Rekognition more directly addresses a need to identify objects or unsafe visual content in uploaded photographs.
  3. Both approaches can be treated as interchangeable because they perform the same underlying operation.
  4. Amazon Rekognition is the primary solution for the stated goal; Amazon Textract is mainly used to identify objects or unsafe visual content in uploaded photographs.

Explanation

Correct Answer

B:

The proposed separation is sound for financial operations. Amazon Textract matches the goal to extract printed text, tables and form fields from scanned invoices: document-understanding APIs return structured information from scanned files; Amazon Rekognition instead meets a need to identify objects or unsafe visual content in uploaded photographs, with a different mechanism: computer-vision APIs analyze images and video frames. The two descriptions should not be reversed.

Incorrect Answers

A:

The two roles have been exchanged in the description. For this financial operations scenario, Amazon Textract addresses the need to extract printed text, tables and form fields from scanned invoices; Amazon Rekognition instead has a different operating mechanism: computer-vision APIs analyze images and video frames.

C:

The interchangeable-service claim ignores that document-understanding APIs return structured information from scanned files. By contrast, computer-vision APIs analyze images and video frames; the financial operations review must therefore distinguish which function it actually needs to extract printed text, tables and form fields from scanned invoices. Image tagging alone would not recover the document layout and key-value fields.

D:

Choosing Amazon Rekognition to extract printed text, tables and form fields from scanned invoices would confuse its intended workload with that of Amazon Textract. Amazon Rekognition is appropriate when a team needs to identify objects or unsafe visual content in uploaded photographs; here the required behavior is that document-understanding APIs return structured information from scanned files.

Question 122

The media publishing architecture review has shortlisted Amazon Rekognition and Amazon Polly for a goal to identify objects or unsafe visual content in uploaded photographs. Which account assigns their capabilities correctly?

  1. Both approaches can be treated as interchangeable because they perform the same underlying operation.
  2. Amazon Rekognition supports the stated goal; Amazon Polly more directly addresses a need to generate natural-sounding spoken audio from supplied text.
  3. Amazon Rekognition is chiefly intended to generate natural-sounding spoken audio from supplied text; Amazon Polly is chiefly intended to identify objects or unsafe visual content in uploaded photographs.
  4. Amazon Polly is the primary solution for the stated goal; Amazon Rekognition is mainly used to generate natural-sounding spoken audio from supplied text.

Explanation

Correct Answer

B:

The proposed separation is sound for media publishing. Amazon Rekognition matches the goal to identify objects or unsafe visual content in uploaded photographs: computer-vision APIs analyze images and video frames; Amazon Polly instead meets a need to generate natural-sounding spoken audio from supplied text, with a different mechanism: the text-to-speech service synthesizes voice output from written content. The two descriptions should not be reversed.

Incorrect Answers

A:

The interchangeable-service claim ignores that computer-vision APIs analyze images and video frames. By contrast, the text-to-speech service synthesizes voice output from written content; the media publishing review must therefore distinguish which function it actually needs to identify objects or unsafe visual content in uploaded photographs. It does not perform document-form field extraction or audio transcription as its primary function.

C:

The two roles have been exchanged in the description. For this media publishing scenario, Amazon Rekognition addresses the need to identify objects or unsafe visual content in uploaded photographs; Amazon Polly instead has a different operating mechanism: the text-to-speech service synthesizes voice output from written content.

D:

Choosing Amazon Polly to identify objects or unsafe visual content in uploaded photographs would confuse its intended workload with that of Amazon Rekognition. Amazon Polly is appropriate when a team needs to generate natural-sounding spoken audio from supplied text; here the required behavior is that computer-vision APIs analyze images and video frames.

Question 123

To label a support request as billing, access, delivery or returns, an insurance operations project must distinguish Multiclass classification from Recommendation modeling. Which proposed description does so accurately?

  1. Recommendation modeling is the primary solution for the stated goal; Multiclass classification is mainly used to rank products that each shopper is likely to prefer.
  2. Multiclass classification is chiefly intended to rank products that each shopper is likely to prefer; Recommendation modeling is chiefly intended to label a support request as billing, access, delivery or returns.
  3. Multiclass classification supports the stated goal; Recommendation modeling more directly addresses a need to rank products that each shopper is likely to prefer.
  4. Both approaches can be treated as interchangeable because they perform the same underlying operation.

Explanation

Correct Answer

C:

The proposed separation is sound for insurance operations. Multiclass classification matches the goal to label a support request as billing, access, delivery or returns: multiclass classification selects among several discrete mutually exclusive categories; Recommendation modeling instead meets a need to rank products that each shopper is likely to prefer, with a different mechanism: recommendation systems use interaction patterns, content features or both to rank items. The two descriptions should not be reversed.

Incorrect Answers

A:

Choosing Recommendation modeling to label a support request as billing, access, delivery or returns would confuse its intended workload with that of Multiclass classification. Recommendation modeling is appropriate when a team needs to rank products that each shopper is likely to prefer; here the required behavior is that multiclass classification selects among several discrete mutually exclusive categories.

B:

The two roles have been exchanged in the description. For this insurance operations scenario, Multiclass classification addresses the need to label a support request as billing, access, delivery or returns; Recommendation modeling instead has a different operating mechanism: recommendation systems use interaction patterns, content features or both to rank items.

D:

The interchangeable-service claim ignores that multiclass classification selects among several discrete mutually exclusive categories. By contrast, recommendation systems use interaction patterns, content features or both to rank items; the insurance operations review must therefore distinguish which function it actually needs to label a support request as billing, access, delivery or returns. A numeric forecast would not naturally represent these named categories.

Question 124

The insurance operations project team sees Binary classification and Regression on the shortlist. For the requirement to decide whether a submitted claim belongs to the suspicious or normal class, which contrast is correct?

  1. Regression is the primary solution for the stated goal; Binary classification is mainly used to estimate the dollar amount of an upcoming invoice from past usage.
  2. Both approaches can be treated as interchangeable because they perform the same underlying operation.
  3. Binary classification is chiefly intended to estimate the dollar amount of an upcoming invoice from past usage; Regression is chiefly intended to decide whether a submitted claim belongs to the suspicious or normal class.
  4. Binary classification supports the stated goal; Regression more directly addresses a need to estimate the dollar amount of an upcoming invoice from past usage.

Explanation

Correct Answer

D:

The proposed separation is sound for insurance operations. Binary classification matches the goal to decide whether a submitted claim belongs to the suspicious or normal class: a classifier maps input features to discrete labels or probabilities over classes; Regression instead meets a need to estimate the dollar amount of an upcoming invoice from past usage, with a different mechanism: regression predicts a continuous numerical quantity based on known examples. The two descriptions should not be reversed.

Incorrect Answers

A:

Choosing Regression to decide whether a submitted claim belongs to the suspicious or normal class would confuse its intended workload with that of Binary classification. Regression is appropriate when a team needs to estimate the dollar amount of an upcoming invoice from past usage; here the required behavior is that a classifier maps input features to discrete labels or probabilities over classes.

B:

The interchangeable-service claim ignores that A classifier maps input features to discrete labels or probabilities over classes. By contrast, regression predicts a continuous numerical quantity based on known examples; the insurance operations review must therefore distinguish which function it actually needs to decide whether a submitted claim belongs to the suspicious or normal class. A continuous amount prediction would require regression instead.

C:

The two roles have been exchanged in the description. For this insurance operations scenario, Binary classification addresses the need to decide whether a submitted claim belongs to the suspicious or normal class; Regression instead has a different operating mechanism: regression predicts a continuous numerical quantity based on known examples.

Question 125

What is the meaningful difference between Amazon Polly and Amazon Textract for a contact-center operations need to generate natural-sounding spoken audio from supplied text?

  1. Amazon Polly is chiefly intended to extract printed text, tables and form fields from scanned invoices; Amazon Textract is chiefly intended to generate natural-sounding spoken audio from supplied text.
  2. Both approaches can be treated as interchangeable because they perform the same underlying operation.
  3. Amazon Textract is the primary solution for the stated goal; Amazon Polly is mainly used to extract printed text, tables and form fields from scanned invoices.
  4. Amazon Polly supports the stated goal; Amazon Textract more directly addresses a need to extract printed text, tables and form fields from scanned invoices.

Explanation

Correct Answer

D:

The proposed separation is sound for contact-center operations. Amazon Polly matches the goal to generate natural-sounding spoken audio from supplied text: the text-to-speech service synthesizes voice output from written content; Amazon Textract instead meets a need to extract printed text, tables and form fields from scanned invoices, with a different mechanism: document-understanding APIs return structured information from scanned files.

B:

The interchangeable-service claim ignores that the text-to-speech service synthesizes voice output from written content. By contrast, document-understanding APIs return structured information from scanned files; the contact-center operations review must therefore distinguish which function it actually needs to generate natural-sounding spoken audio from supplied text. Speech recognition works in the opposite direction and requires a different capability.

C:

Choosing Amazon Textract to generate natural-sounding spoken audio from supplied text would confuse its intended workload with that of Amazon Polly. Amazon Textract is appropriate when a team needs to extract printed text, tables and form fields from scanned invoices; here the required behavior is that the text-to-speech service synthesizes voice output from written content.

Question 126

A financial operations review examines Regression in relation to the need to estimate the dollar amount of an upcoming invoice from past usage. Which TWO statements are technically sound? (Choose TWO.)

  1. Regression predicts a continuous numerical quantity based on known examples.
  2. The main purpose of Regression is to identify groups of shoppers when no segment labels have been provided instead of to estimate the dollar amount of an upcoming invoice from past usage.
  3. The described method removes the need to consider the stated limitation because anomaly detection scores deviations from expected behavior rather than predicting a fixed quantity.
  4. It does not directly produce a category such as high or low risk unless thresholds are added.
  5. Regression operates according to this purported mechanism: recommendation systems use interaction patterns, content features or both to rank items.

Explanation

Question 127

For a telecommunications use case that must extract entities, sentiment or categories from unstructured customer reviews, the team is choosing between Amazon Comprehend and Amazon Transcribe. Which distinction is sound?

  1. Amazon Comprehend supports the stated goal; Amazon Transcribe more directly addresses a need to convert recorded English-language calls into searchable written transcripts.
  2. Amazon Transcribe is the primary solution for the stated goal; Amazon Comprehend is mainly used to convert recorded English-language calls into searchable written transcripts.
  3. Amazon Comprehend is chiefly intended to convert recorded English-language calls into searchable written transcripts; Amazon Transcribe is chiefly intended to extract entities, sentiment or categories from unstructured customer reviews.
  4. Both approaches can be treated as interchangeable because they perform the same underlying operation.

Explanation

Correct Answer

A:

The proposed separation is sound for telecommunications. Amazon Comprehend matches the goal to extract entities, sentiment or categories from unstructured customer reviews: natural-language analysis identifies meaning and features within text; Amazon Transcribe instead meets a need to convert recorded English-language calls into searchable written transcripts, with a different mechanism: the managed speech-to-text service derives text from spoken audio. The two descriptions should not be reversed.

Incorrect Answers

B:

Choosing Amazon Transcribe to extract entities, sentiment or categories from unstructured customer reviews would confuse its intended workload with that of Amazon Comprehend. Amazon Transcribe is appropriate when a team needs to convert recorded English-language calls into searchable written transcripts; here the required behavior is that natural-language analysis identifies meaning and features within text.

C:

For this telecommunications scenario, Amazon Comprehend addresses the need to extract entities, sentiment or categories from unstructured customer reviews; Amazon Transcribe instead has a different operating mechanism: the managed speech-to-text service derives text from spoken audio.

D:

The interchangeable-service claim ignores that natural-language analysis identifies meaning and features within text. By contrast, the managed speech-to-text service derives text from spoken audio; the telecommunications review must therefore distinguish which function it actually needs to extract entities, sentiment or categories from unstructured customer reviews. It is not designed primarily to act as a conversational bot or speech synthesizer.
