NEW QUESTION # 131
Does this describe the role of Control Groups (cgroups) when used with a Docker container?
Solution: role-based access control to clustered resources
Answer: A
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 # 132
Is this the purpose of Docker Content Trust?
Solution: Enable mutual TLS between the Docker client and server.
Answer: A
Explanation:
Explanation
= Docker Content Trust (DCT) is a feature that allows users to verify the integrity and publisher of container images they pull or deploy from a registry server, signed on a Notary server12. DCT does not enable mutual TLS between the Docker client and server, which is a different security mechanism that ensures encrypted and authenticated communication between the client and the server3. DCT is based on digital signatures and The Update Framework (TUF) to provide trust over arbitrary collections of data1. References:

NEW QUESTION # 133
Which docker run` flag lifts cgroup limitations?
Answer: C
Explanation:
Explanation
The --privileged flag lifts all the cgroup limitations for a container, as well as other security restrictions imposed by the Docker daemon1. This gives the container full access to the host's devices, resources, and capabilities, as if it was running directly on the host2. This can be useful for certain use cases that require elevated privileges, such as running Docker-in-Docker or debugging system issues3. However, using the
--privileged flag also poses a security risk, as it exposes the host to potential attacks or damages from the container4. Therefore, it is not recommended to use the --privileged flag unless absolutely necessary, and only with trusted images and containers.
The other options are not correct because they do not lift all the cgroup limitations for a container, but only affect specific aspects of the container's resource allocation or isolation:
*The --cpu-period flag sets the CPU CFS (Completely Fair Scheduler) period for a container, which is the length of a CPU cycle in microseconds. This flag can be used in conjunction with the --cpu-quota flag to limit the CPU time allocated to a container. However, this flag does not affect other cgroup limitations, such as memory, disk, or network.
*The --isolation flag sets the isolation technology for a container, which is the mechanism that separates the container from the host or other containers. This flag is only available on Windows containers, and can be used to choose between process, hyperv, or process-isolated modes. However, this flag does not affect the cgroup limitations for a container, but only the level of isolation from the host or other containers.
*The --cap-drop flag drops one or more Linux capabilities for a container, which are the privileges that a process can use to perform certain actions on the system. This flag can be used to reduce the attack surface of a container by removing unnecessary or dangerous capabilities. However, this flag does not affect the cgroup limitations for a container, but only the capabilities granted to the container by the Docker daemon.

NEW QUESTION # 134
You created a new service named 'http' and discover it is not registering as healthy. Will this command enable you to view the list of historical tasks for this service?
Solution: 'docker service inspect http'
Answer: A
Explanation:
Explanation
= The command 'docker service inspect http' will display detailed information on the 'http' service, such as its ID, name, mode, replicas, container spec, networks, ports, etc. However, it will not show the list of historical tasks for the service. To view the list of tasks, you need to use the command 'docker service ps http', which will show the ID, name, image, node, desired state, current state, and error of each task12. References:
