Question 5

Your customer has deployed their microservices based application on Oracle Container Engine for Kubernetes (OKE) and they are using Oracle Cloud Infrastructure Registry (OCIR) service as their Docker image repository. They have deployed the OKE cluster using the 'custom create' option, and their Virtual Cloud Network (VCN) has three public subnets with associated route tables, security lists, and an internet gateway. They are facing an issue where their application containers are falling to deploy. Upon investigation, they learn that the images are not getting pulled from the designated OCIR repository. The YAML configuration has the correct path to the images. What is a valid concern that needs to be further investigated?

Options :

A : They need to add a security list rule for TCP port 22 to connect to the OCIR service.

B : The VCN hosting the OKE cluster worker nodes needs to have a NAT gateway to access OCIR repositories.

C : They need to add IAM credentials for each user that deploys applications to the OKE cluster.

D : The OKE cluster needs to have a secret with credentials of their OCIR repository and use that secret in the Kubernetes deployment manifest.
