Selected Answer: B

The BEST deployment strategy to meet the given requirements is the "Blue-green" deployment. In a blue-green deployment, two identical environments are maintained, one for production (blue) and the other for the next version or release (green). All production traffic is initially directed to the blue environment, while the green environment is prepared and tested thoroughly without affecting the production environment. Once the green environment is ready, the traffic is switched instantly from the blue to the green environment using traffic control, with no downtime or impact on users.

Selected Answer: B

• Blue-green deployment These deployments always have an active system and one that is used for testing. When testing is complete, the testing system becomes active, and the former production system is available for testing. One system is labeled “blue” and the other “green.”
