Question 2

Single choice

An Alexa Skill Builder is troubleshooting issues with a custom skill backed by an AWS Lambda function that integrates with an external API controlling a light bulb. The Builder observes that when saying "Alexa, turn on the light" the response is "light is not responding" and 10 seconds later, the light turns on.

What is the MOST likely cause for this issue and how can it be solved?

A
The Lambda function is not executing fast enough. Double the currently specified Lambda memory allocation in the Lambda basic settings section.
B
The default Lambda function timeout setting is too short and the Lambda function times out before the response from the external API can be processed and a reply can be sent back to Amazon Alexa.
Increase the Lambda timeout limit.
C
There are too many concurrent Lambda functions running, causing the existing Lambda function to block and then time out before a response can be returned to Amazon Alexa. Increase the Lambda function reserve concurrency value to 30, then verify that the function can complete its work within 10 seconds.
D
There is a bug in the Lambda function code preventing the external API from being called. Enable Lambda debugging and error handling and check Amazon CloudWatch Logs for the error, then modify the code accordingly.

Question 5

Single choice

An Alexa Skill Builder receives feedback from users that a specific utterance causes Amazon Alexa to trigger the skill's AMAZON.HelpIntent rather than triggering the correct intent and slot.

How can the Builder reproduce this behavior to troubleshoot the problem?

B
Set up a unit test in the code base to simulate what happens when the given intent and slot combination are dispatched within the skill.
C
Use the Manual JSON tab on the Test page of the developer console to see what happens when a request for the given intent and slot combination is sent to the skill
D
Use the Alexa Simulator tab on the Test page of the developer console to test the utterances the users have reported.

Question 9

Single choice

A travel booking skill has slot elicitation for fromCity, toCity, and travelDate inside of a dialog. After going live, the skill is getting negative reviews stating that the skill does not understand the city names when customers try to book travel.

Why will the addition of AMAZON.FallbackIntent fail to resolve the customer issue?

A
AMAZON.FallbackIntent will not be triggered in the middle of a dialog.
B
A handler cannot be added to a Live skill.
C
AMAZON.FallbackIntent will cause the slot values to be incorrectly mapped.
D
AMAZON.FallbackIntent cannot be present in a skill with a Dialog directive.
