To obtain information about the UUIDs of all disks attached to a Linux system, the administrator can run the command blkid (B). This will display the block device attributes, including the UUID, label, type, and partition information. The other commands are not related to this task. References:

Ansible is an open-source automation tool that can manage multiple systems simultaneously. Using an Ansible playbook, the administrator can run commands across several servers to obtain the installed kernel version efficiently. A simple ansible all -m command -a "uname -r" will retrieve the kernel version from all target systems.

To create a symlink for /usr/local/bin/app-a, which was installed in /usr/local/share/app-a, the administrator can use the command ln -s /usr/local/share/app-a /usr/local/bin/app-a (A). This will create a symbolic link named /usr/local/bin/app-a that points to the original file /usr/local/share/app-a. The other commands will not create a symlink, but either move, copy, or synchronize the file. References:
