A database specialist wants to load some XML data from an S3 bucket into an Amazon RDS database. What is the optimal solution to accomplish this?

Answer options:

A.Use AWS Lambda Function to read the file and import the data into the database.
B.Use AWS Data Pipeline to read the file and import the data into the database.
C.Use AWS CLI to read the file and import the data into the database.
D.Use LOAD XML FROM S3 SQL statement to import the data into the database.

Answer: D
Option A is incorrect because this is not the optimal solution as it requires the implementation of a custom AWS Lambda function. A simpler and more cost-effective solution is to use Amazon RDS native capability to import the data.
Option B is incorrect because this is not the optimal solution as it requires the implementation of a custom EMR job and configuration of Data Pipelines and EMR clusters. A simpler and more cost-effective solution is to use Amazon RDS native capability to import the data.
Option C is incorrect because there is no RDS CLI command to import XML data from S3 into a database.
Option D is CORRECT because the simplest solution is to use LOAD XML FROM S3 SQL statement to import the XML file from the S3 bucket into the database.
