Exam questions and Answers 2026
You have an app that needs 25 items of 13KB per second. Your app uses STRONGLY
consistent reads. What should the throughput be set to? (Math problem) - ANSWER-
Calculate read capacity units (items up to 4 KB in size)
Multiply number of items by read capacity units
Do NOT divide by 2 because strongly consistent
Answer: 100
One read capacity unit represents one strongly consistent read per second, or two
eventually consistent reads per second, for items up to 4 KB in size? - ANSWER-True
When you create a table, you specify how much provisioned throughput capacity you
want to reserve for reads and writes? - ANSWER-True
One read capacity unit represents one X type of read per second, or two Y type of read
per second? - ANSWER-One strongly consistent read per second. Two eventually
consistent reads per second. For items up to 4 KB in size.
Application needs to read 25 items of 13KB per second. App uses EVENTUALLY
consistent reads. What should you set read throughput to? - ANSWER-Calculate read
capacity units (items up to 4 KB in size).
Multiply number of items by read capacity units.
Divide by two because EVENTUALLY consistent.
Answer: 50
A global secondary index contains a selection of attributes from the table, but are
organized by a primary key that is different from the table's? (T/F) - ANSWER-True
You have a fleet of EC2 instances that are constantly polling empty SQS queues which
is burning CPU complete cycles. What should you do? - ANSWER-Enable SQS long
polling
What is the default SQS visibility time out? - ANSWER-30 seconds
AWS SQS long polling allows the SQS service to wait until a message is available in the
queue before sending a response? - ANSWER-true
A visibility timeout is a period of time during which AWS SQS prevents other consuming
components from receiving and processing the message? - ANSWER-true
, What AWS service can you use to "fan out" SQS messages to multiple queues? -
ANSWER-SNS
(SQS) What is the maximum long poll timeout? - ANSWER-20 seconds
EC2 instances download jobs from SQS queue, but are taking too long to process.
What api call can you use to the length of time to process jobs? - ANSWER-
ChangeMessageVisibility
(SQS) You are designing a new app which processes payments and delivers
promotional emails to customers. Your need to ensure that the payment process takes
priority over the creation of emails. What is the best way to achieve this? - ANSWER-
Use 2 SQS queues. Poll that payment queue first.
An SQS message can NOT be delivered multiple times? - ANSWER-False, SQS
messages can be delivered multiple times
What is the default visibility timeout for SQS? - ANSWER-30 seconds
How long can SQS messages be? - ANSWER-Messages can contain up to 256 KB of
text in any format
SQS was the second service on AWS? - ANSWER-False, SQS was the first
DynomaDB writes are measured in 2 KB per write? - ANSWER-False, they are
measured in 1 KB per write.
What are the two consistency models used when reading data from DynamoDB? -
ANSWER-Eventually Consistent and Strongly consistent
DynamoDB is a NoSQL database by AWS? - ANSWER-True
In DynamoDB, you specify provisioned throughput requirements in terms of capacity
units? - ANSWER-True
DynamoDB local secondary indexes are fixed at 10 per table? - ANSWER-False, local
secondary indexes are fixed at 5 per table.
Local secondary indexes give your table a choice of sort keys? - ANSWER-True
What are the three capacity unit sizes in DynamoDB? - ANSWER-One read capacity
unit represents one strongly consistent read per second, for items up to 4 KB in size.
One read capacity unit represents two eventually consistent reads per second, for items
up to 4 KB in size.
One write capacity unit represents one write per second for items up to 1 KB in size.
