NEW QUESTION # 56
Does this describe the role of Control Groups (cgroups) when used with a Docker container?
Solution: role-based access control to clustered resources

A. Yes
B. No

Answer: B

Explanation:
= The role of Control Groups (cgroups) when used with a Docker container is not role-based access control to clustered resources. Cgroups are a feature of the Linux kernelthat allow you to limit, manage, and isolate resource usage of collections of processes running on a system1. Resources are CPU time, system memory, network bandwidth, or combinations of these resources, and so on2. Cgroups allow Docker Engine to share available hardware resources to containers and optionally enforce limits and constraints3. Cgroups can help avoid "noisy neighbor" issues and improve the performance and security of containers4. Role-based access control (RBAC) is a different concept that refers to controlling access to resources based on the roles of individual users within an organization5.

NEW QUESTION # 57
You add a new user to the engineering organization in DTR.
Will this action grant them read/write access to the engineering/api repository?
Solution: Add the user directly to the list of users with read/write access under the repository's Permissions tab.

A. Yes
B. No

Answer: A

Explanation:
Explanation
This action will grant them read/write access to the engineering/api repository, because adding a user directly to the list of users with read/write access under the repository's Permissions tab is one way to grant permissions to a user in DTR. According to the official documentation, this is an example of using fine-grained permissions for a repository.

NEW QUESTION # 58
Does this command display all the pods in the cluster that are labeled as 'env: development'?
Solution: 'kubectl get pods -I env=development'

A. Yes
B. No

Answer: A

NEW QUESTION # 59
Will this action upgrade Docker Engine CE to Docker Engine EE?
Solution: Delete '/var/lib/docker' directory.

A. Yes
B. No

Answer: B

Explanation:
Explanation
Deleting the /var/lib/docker directory will not upgrade Docker Engine CE to Docker Engine EE. It will only remove all the data stored by Docker, such as images, containers, volumes, and networks. This can cause data loss and disrupt the running services. To upgrade from Docker Engine CE to Docker Engine EE, you need to follow the official instructions from Docker, which involve uninstalling the CE package and installing the EE package. You also need to have a valid license to use Docker Engine EE. References:

* Install Docker Engine
* Moving from docker ce to docker-EE - Stack Overflow

NEW QUESTION # 60
Will a DTR security scan detect this?
Solution: licenses for known third party binary components

A. Yes
B. No

Answer: A

Explanation:
A DTR security scan will detect licenses for known third party binary components. This is because DTR security scan uses a database of vulnerabilities and licenses that is updated regularly from Docker Server1. DTR security scan can identify the components and versions of the software packages that are present in the image layers, and report any known vulnerabilities or licenses associated with them2. This can help users to comply with the licensing requirements and avoid potential legal issues3. Reference:
