hard🚀 Application Q8 of 15

DynamoDB - with AWS SDK

AManually call DynamoDB REST API endpoints for each table.

BUse a single command that fetches all items from all tables at once.

CUse ListTablesCommand to get tables, then loop with GetItemCommand for each table.

DCreate tables dynamically inside the SDK before fetching items.

Step-by-Step Solution

Solution:

Step 1: Identify correct SDK usage for listing and fetching
ListTablesCommand lists tables; then GetItemCommand fetches items per table.
Step 2: Evaluate other options
Manual REST calls bypass SDK benefits. No single command fetches all items from all tables. Creating tables dynamically is unrelated.
Final Answer:
Use ListTablesCommand to get tables, then loop with GetItemCommand for each table. -> Option C
Quick Check:
SDK chaining commands = ListTables + GetItem [OK]

Quick Trick: Chain ListTables and GetItem commands for multi-table access [OK]

Common Mistakes:

MISTAKES

Trying to fetch all items with one command
Ignoring SDK and using manual REST calls
Confusing table creation with data fetching
