Question

A company wants to use a grid system for a proprietary enterprise in-memory data store on top of AWS. This system can run in multiple server nodes in any Linux-based distribution. The system must be able to reconfigure the entire cluster every time a node is added or removed. When adding or removing nodes, an /etc/cluster/nodes.config file must be updated, listing the IP addresses of the current node members of that cluster. The company wants to automate the task of adding new nodes to a cluster. What can a DevOps engineer do to meet these requirements?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Use AWS OpsWorks Stacks to layer the server nodes of that cluster. Create a Chef recipe that populates the content of the /etc/cluster/nodes.config file and restarts the service by using the current members of the lay... AWS Config tracks resource configuration changes and evaluates compliance.
