easy📝 Syntax Q3 of 15
Step-by-Step Solution
Solution:
Step 1: Check correct key type and attribute type
Partition key uses KeyType=HASH and attribute type S (string) or N (number).Step 2: Validate syntax correctness
aws dynamodb create-table --table-name Orders --attribute-definitions AttributeName=OrderId,AttributeType=S --key-schema AttributeName=OrderId,KeyType=HASH --provisioned-throughput ReadCapacityUnits=5,WriteCapacityUnits=5 uses KeyType=HASH and AttributeType=S correctly; others have wrong KeyType or invalid AttributeType.Final Answer:
aws dynamodb create-table --table-name Orders --attribute-definitions AttributeName=OrderId,AttributeType=S --key-schema AttributeName=OrderId,KeyType=HASH --provisioned-throughput ReadCapacityUnits=5,WriteCapacityUnits=5 -> Option BQuick Check:
Partition key = KeyType HASH + valid AttributeType [OK]
Quick Trick: Partition key must be KeyType HASH with valid attribute type [OK]
Common Mistakes:
MISTAKES- Using KeyType RANGE for partition key
- Using invalid attribute types like Z
- Mixing attribute and key schema order
