NEW QUESTION # 577
A cloud engineer is asked to copy the file deployment.yaml from a container to the host where the container is running. Which of the following commands can accomplish this task?
A. docker cp container_id/deployment.yaml local://deployment.yaml
B. docker cp container_id/deployment.yaml deployment.yaml
C. docker cp container_id:/deployment.yaml deployment.yaml
D. docker cp deployment.yaml local://deployment.yaml
Answer: C
Explanation:
The command docker cp container_id:/deployment.yaml deployment.yaml can accomplish the task of copying the file deployment.yaml from a container to the host. The docker command is a tool for managing Docker containers and images. The cp option copies files or directories between a container and the local filesystem. The container_id is the identifier of the container, which can be obtained by using the docker ps command. The /deployment.yaml is the path of the file in the container, which must be preceded by a slash. The deployment.yaml is the path of the file on the host, which can be relative or absolute. The command docker cp container_id:/deployment.yaml deployment.yaml will copy the file deployment.yaml from the container to the current working directory on the host. This is the correct command to use to accomplish the task. The other options are incorrect because they either use the wrong syntax (docker cp container_id/deployment.yaml deployment.yaml or docker cp container_id/deployment.yaml local://deployment.yaml) or do not exist (docker cp deployment.yaml local://deployment.

NEW QUESTION # 578
Which of the following is the main purpose of SSO?
A. To be an essential component for managing authentication, authorization, and identity information
B. To allow a user to authenticate once and have access to multiple applications or systems without having to log in again
C. To serve as an information protection mechanism that protects identities with administrative access
D. To add an extra layer of protection, reducing the risk of unauthorized access, requiring more than just a password to access
Answer: B
Explanation:
SSO (Single Sign-On) allows users to authenticate once and gain access to multiple systems or services without re-authenticating. This improves user experience and reduces the number of credentials users must manage.

NEW QUESTION # 579
One leg of an LVM-mirrored volume failed due to the underlying physical volume, and a systems administrator is troubleshooting the issue. The following output has been provided:
Given this scenario, which of the following should the administrator do to recover this volume?
A. Reboot the server. The volume will revert to stripe mode.
B. Reboot the server. The volume will automatically go back to linear mode.
C. Replace the failed drive and reconfigure the mirror.
D. Recreate the logical volume.
Answer: C
Explanation:
The administrator should replace the failed drive and reconfigure the mirror to recover the volume. The LVM (Logical Volume Manager) is a tool for managing disk space on Linux systems. The LVM allows the administrator to create logical volumes that span across multiple physical volumes, such as hard disks or partitions. The LVM also supports different types of logical volumes, such as linear, striped, or mirrored. A mirrored logical volume is a type of logical volume that creates a copy of the data on another physical volume, providing redundancy and fault tolerance. The output shows that the logical volume is mirrored and that one leg of the mirror has failed due to the underlying physical volume. This means that one of the physical volumes that contains the data of the logical volume is damaged or missing. This can cause data loss and performance degradation. The administrator should replace the failed drive and reconfigure the mirror to recover the volume. The administrator should identify the failed physical volume by using commands such as pvdisplay, vgdisplay, or lvdisplay. The administrator should then remove the failed physical volume from the volume group by using the vgreduce command. The administrator should then install a new drive and create a new physical volume by using the pvcreate command. The administrator should then add the new physical volume to the volume group by using the vgextend command. The administrator should then reconfigure the mirror by using the lvconvert command. The administrator should replace the failed drive and reconfigure the mirror to recover the volume. This is the correct answer to the question. The other options are incorrect because they either do not recover the volume (reboot the server. The volume will automatically go back to linear mode or reboot the server. The volume will revert to stripe mode) or do not preserve the data of the volume (recreate the logical volume).
