    An Alexa Skill Builder wants to add a short audio clip to a skill with SSML. The Builder records a 6-second audio clip using a high-end microphone and recording application and exports the file with a bitrate of 48 kbps. The file is then uploaded to a public Amazon S3 bucket. The Builder then updates the SSML to return: When testing the skill, Amazon Alexa responds with "There was a problem with the requested skill's response" every time. How should the Builder resolve this error?

    Choose one answer.

    

    • Record a shorter audio clip.

11. Question 11 · 1

    During testing of a new Amazon Alexa skill, the skill is repeatedly failing and invoking the function defined in the addErrorHandler method specified on the SkillBuilder object. Upon inspection of Amazon CloudWatch Logs, the Alexa Skill Builder establishes that the failure is occurring whenever AMAZON.HelpIntent is being received. How should this error be corrected?

    Choose one answer.

    • AMAZON.HelpIntent should be handled by the SDK. The Builder should raise a support ticket with Amazon.
    • The Builder should ensure that the intent handler is coded so that it tests for AMAZON.HelpIntent in its canHandle method, and when detected, returns true.
    • The Builder should add logic to provide help instructions to the function defined in the addErrorHandler method specified on the SkillBuilder object.
    • The Builder should add an AMAZON.HelpIntent entry to the interaction model to ensure the request for help is recognized by the skill.

12. Question 12 · 1
