Scanning images to detect any security vulnerability is not a function of UCP. UCP stands for Universal Control Plane, which is a web-based user interface for managing Docker Enterprise clusters and applications. UCP does not provide image scanning capabilities, but it integrates with Docker Trusted Registry (DTR), which does offer image scanning as part of its security features.

Correct Answer: B

his is not a way to accomplish this, because creating one pod and adding all the resources needed for each application is not a good practice for deploying applications in Kubernetes. According to the official documentation, pods are not intended to run multiple instances of an application or different applications that are tightly coupled. Pods are also not meant to hold resources that are shared across applications, such as secrets or configMaps.

Correct Answer: B

Setting and exporting the IGNORE_TLS environment variable on the command line is not a way to configure the Docker engine to use a registry without a trusted TLS certificate. The IGNORE_TLS environment variable is not recognized by Docker and has no effect on its behavior. To configure the Docker engine to use a registry without a trusted TLS certificate, you need to either set INSECURE_REGISTRY in the /etc/docker/default configuration file or add --insecure-registry flag to the dockerd command.
