An Application Running on Amazon EC2 Instances Needs to Write

question 36

Multiple Choice

An application running on Amazon EC2 instances needs to write files to an Amazon S3 bucket. What is the MOST secure way to grant the application access to the S3 bucket?

• A) Create an IAM user with the necessary privileges. Generate an access key and embed the key in the code running on the EC2 instances.
• B) Install secure FTP (SFTP) software on the EC2 instances. Use an AWS Lambda function to copy the files from the EC2 instances to Amazon S3 using SFTP.
• C) Create an IAM role with the necessary privileges. Associate the role with the EC2 instances at launch.
• D) Use rsync and cron to set up the transfer of files from the EC2 instances to the S3 bucket. Enable AWS Shield to protect the data.

Definitions:

Series RL Circuit

An electrical circuit composed of resistors (R) and inductors (L) connected in series, characterized by the resistance and inductive reactance that influence the circuit's total impedance.

Inductive Reactance

The opposition that inductors present to alternating current, due to the magnetic field created around it, measured in Ohms.

True Power

The actual power in watts consumed or produced by an electrical device, distinct from reactive or apparent power.

Series RL Circuit

A series RL circuit is an electrical circuit comprising a resistor (R) and an inductor (L) connected in series, used to filter signals or store energy.
