AWS - DynamoDB

Given this AWS CLI command:

aws dynamodb create-table --table-name Products --attribute-definitions AttributeName=ProductId,AttributeType=S AttributeName=Category,AttributeType=S --key-schema AttributeName=ProductId,KeyType=HASH AttributeName=Category,KeyType=RANGE --provisioned-throughput ReadCapacityUnits=10,WriteCapacityUnits=5

What is the primary key type of the Products table?

ANo primary key defined

BSimple primary key with only a HASH key

CComposite primary key with HASH and RANGE keys

DPrimary key with only a RANGE key

Step-by-Step Solution

Solution:

Step 1: Analyze the key schema in the command
The command defines two keys: ProductId as HASH and Category as RANGE.
Step 2: Understand primary key types in DynamoDB
A primary key with both HASH and RANGE keys is called a composite primary key.
Final Answer:
Composite primary key with HASH and RANGE keys -> Option C
Quick Check:
HASH + RANGE = composite key [OK]

Quick Trick: HASH + RANGE keys mean composite primary key [OK]

Common Mistakes:

Thinking two attributes mean no key
Confusing RANGE key as standalone primary key
Ignoring key-schema details
