Your organization is planning to use AWS ECS for docker applications. However, they would like to apply 3rd party monitoring tools on the ECS container instances to monitor the instances. They approached you asking for a recommendation. What do you suggest?

Answer options:

A.AWS ECS is a managed service. Customers cannot install 3rd party software. Use CloudWatch for monitoring metrics.
B.Customers will have control over AWS ECS container instances and can set up monitoring like a normal EC2 instance.
C.Consult AWS Support team to install 3rd party software on ECS. The support team will review the case and install if 3rd party software is in their trusted software entries.
D.AWS ECS is a managed service. Customers cannot install 3rd party software. Use application-level monitoring.

Answer: B
Options A and D are incorrect because AWS ECS uses EC2 instances with ECS-optimized AMI. You will have root access to the instances and you can manage them.
Option C is incorrect as it is just a distractor, there is no need for a support team.
