Is this a function of UCP?
Solution: scans images to detect any security vulnerability
= Scanning images to detect any security vulnerability is a function of UCP.UCP integrates with Docker Trusted Registry (DTR), which is a secure and scalable image storage solution1.DTR has a built-in image scanning feature that checks every layer of every image for known vulnerabilities and displays the results in the UCP web UI2. This helps users to identify and fix any security issues before deploying their applications.UCP also allows users to enforce security policies and only allow running applications that use images that are scanned and free of vulnerabilities3.Reference:

You set up an automatic pruning policy on a DTR repository to prune all images using Apache licenses.
What effect does this have on images in this repository?
Two development teams in your organization use Kubernetes and want to deploy their applications while ensuring that Kubernetes-specific resources, such as secrets, are grouped together for each application.
Is this a way to accomplish this?
Solution. Create a collection for for each application.
= Creating a collection for each application is not a way to accomplish this.A collection is a term used by Ansible to describe a package of related content that can be used to automate the management of Kubernetes resources1. A collection is not a native Kubernetes concept and does not group resources together within the cluster. To group Kubernetes-specific resources, such as secrets, for each application, you need to use namespaces.A namespace is a logical partition of the cluster that allows you to isolate resources and apply policies to them2. You can create a namespace for each application and store the secrets and other resources in that namespace. This way, you can prevent conflicts and limit access to the resources of each application.To create a namespace, you can use the kubectl create namespace command or a yaml file2.To create a secret within a namespace, you can use the kubectl create secret commandwith the --namespace option or a yaml file with the metadata.namespace field3.Reference:

In the context of a swarm mode cluster, does this describe a node?
Solution: a physical machine participating in the swarm
A node is a physical or virtual machine running Docker Engine in swarm mode1.A node can be either a manager or a worker, depending on its role in the cluster1.A physical machine participating in the swarm is a node, regardless of its role or availability2.Reference:

Will this sequence of steps completely delete an image from disk in the Docker Trusted Registry?
