AWS - DynamoDB
A developer sets a DynamoDB table to provisioned mode but forgets to specify write capacity units. What will happen when the table is created?
ATable is created but write operations are throttled immediately
BTable creation fails due to missing write capacity units
CTable is created in on-demand mode automatically
DTable is created with default write capacity units of 5
Step-by-Step Solution
Solution:

  1. Step 1: Understand required parameters for provisioned mode

    Both read and write capacity units are mandatory when creating a provisioned table.

  2. Step 2: Identify behavior when write units are missing

    Missing write capacity units causes table creation to fail with an error.

  3. Final Answer:

    Table creation fails due to missing write capacity units -> Option B

  4. Quick Check:

    Missing capacity units = creation failure [OK]
Quick Trick: Provisioned mode requires both read and write units [OK]
Common Mistakes:
  • Assuming default units are assigned
  • Thinking mode switches automatically
  • Believing table creates with throttling only
