Which of the following can be added or changed after the creation of a DynamoDB table?
7.
Question 7
How many Scan queries need to be sent to DynamoDB to get all the items from the table if the table contains 10 items each with 200KB of data?
12.
Question 12
Which of the following statement is FALSE concerning secondary indexes in DynamoDB?
14.
Question 14
What feature of DynamoDB is necessary to make use of Optimistic Locking?
4.
Question 4
The metric of ConsumedReadCapacityUnits is currently much lower than the Read Capacity Unit provisioned on a DynamoDB table. However, users are saying that they are receiving an error message of ProvisionedThroughputExceededException. What could be the issue?
8.
Question 8
A DynamoDB table is made up of a Partition Key of UserID, a Sort Key with the date and time and an attribute of Score providing the list of all the scores for a game. A dashboard needs to display the 5 highest scores from the table. What is the most efficient way to keep this dashboard in real time?
15.
Question 15
Given a table that has a Partition Key of UserID, an attribute named AccountLocked and many other attributes. The AccountLocked attribute is set to TRUE when the UserID is has its account locked and isn’t set when it’s not locked. Not many accounts are typically locked at a time compared to the hundreds of thousands of users in that table. What would be the most optimal way to get a list of all UserID that have their account locked (AccountLocked set to TRUE)?
3.

Question 9
How can the data at rest that was encrypted by DynamoDB be decrypted?
- In the query to DynamoDB, send the key to use to decrypt it and let DynamoDB handle the decryption.
- Send a query to DynamoDB as normal and let it transparently decrypt the data.
- Send a query to DynamoDB and use the AWS Key Management Service to decrypt the data on the client side.
10.
