First table creation in DynamoDB - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the primary purpose of creating a table in DynamoDB?

A table in DynamoDB stores data as items, similar to rows in a spreadsheet. It organizes your data so you can add, read, and manage it easily.

What is a primary key in DynamoDB table creation?

The primary key uniquely identifies each item in the table. It can be a simple key (one attribute) or a composite key (partition key and sort key).

Which attribute types can be used for the primary key in DynamoDB?

You can use String (S), Number (N), or Binary (B) types for the primary key attributes.

What is the difference between a partition key and a sort key in DynamoDB?

The partition key determines the partition where data is stored. The sort key allows sorting and organizing items with the same partition key.

Why do you need to specify read and write capacity units when creating a DynamoDB table?

Read and write capacity units control how much data your table can handle per second. They help manage performance and cost.

What is the minimum required attribute when creating a DynamoDB table?

A Secondary index

B Sort key

C Primary key

D Provisioned throughput

Every DynamoDB table must have a primary key defined to uniquely identify items.

Which of the following is NOT a valid data type for a DynamoDB primary key?

A Binary

B Number

C String

D Boolean

Boolean is not a valid data type for primary key attributes in DynamoDB.

What does the partition key in DynamoDB determine?

A The physical storage partition

B The table name

C The order of items

D The read capacity

The partition key decides which physical partition stores the data.

When creating a table, what do read capacity units control?

A Number of tables

B Number of strongly consistent reads per second

C Number of attributes

D Data storage size

Read capacity units control how many strongly consistent reads per second the table can handle.

Which key type allows sorting items with the same partition key?

A Sort key

B Primary key

C Partition key

D Secondary key

The sort key lets you sort and organize items that share the same partition key.

Explain the steps and key elements needed to create your first DynamoDB table.

Think about what uniquely identifies data and how much data you expect to handle.

Describe the difference between a partition key and a sort key in DynamoDB and why each is important.

Imagine organizing files in folders and sorting them inside.
