4. When a failure occurs during stack creation in Cloudformation, does a rollback occur?

A. True

B. False

This feature makes you depend on the fact that stacks may either be fully created or not at all. It simplifies the layered solutions system administration built on the top of the AWS CloudFormation.

11. A Global Secondary Index can have a different partition key and sort key from those of its base table. 

A. True

B. False

Answer: A

AWS Console Test:

AWS Developer Associate Exam Questions
The table is created successfully.

AWS Developer Associate Exam Questions

So now we have seen that we can create GSI with the same partition key as the Base table. 

Global secondary index — Global secondary index is an index where both the partition key and sort key can be different from that of the base table. The global secondary index is named as global because here the queries can span all the data in the base table over all the partitions.

Local secondary index — Local secondary index is an index where the partition key is the same as that of the base table, while sort key is different. The local secondary index is named as local as all the partitions here are scoped to a base table partition having the same partition key value.

13. An IT admin has enabled long polling in their SQS queue. What must be done for long polling to be enabled in SQS? Choose the correct answer from the options below

A. Create a dead letter queue

B. Set the message size to 256KB

C. Set the ReceiveMessageWaitTimeSeconds property of the queue to 0 seconds

D. Set the ReceiveMessageWaitTimeSeconds property of the queue to 20 seconds

Answer: D

Explanation: Amazon SQS long polling is a method of retrieval of messages from SQS queues. It returns a response only when a message arrives in the message queue instead of short polling where the response returns immediately even when the message is empty.

As the messages are available, the retrieval of messages from Amazon SQS becomes inexpensive due to long polling. It may also reduce the cost of using SQS as it can reduce the empty receipts.
