1Z0-1109-25 practice question 3 of 10

Your team is responsible for deploying a new version of an application that is being used by your company’s finance department. The application is critical to the department’s operations, and any downtime could have serious consequences. What is the recommended approach in OCI for creating environments for this scenario?

Answer options

A: Deploy the application to two separate OCI tenancies to ensure complete isolation between environments.

B: Use a single Kubernetes cluster with two node pools, one for the blue-green environment and one for the canary environment. Correct answer

C: Configure two OKE clusters, selecting the blue-green traffic shift strategy using a load balancer.

D: Use a single OCI region and create two separate Virtual Cloud Networks (VCNs), one for the blue environment and one for the green environment.

Correct Answer:

B. Use a single Kubernetes cluster with two node pools, one for the blue-green environment and one for the canary environment.

Explanation

For critical applications, such as the one used by the finance department, a blue-green deployment strategy is recommended to ensure minimal or zero downtime during upgrades. The blue-green strategy involves running two separate environments: blue (current version) and green (new version).
