Nice, but what if a host isn't in any group?

Wait, does it really overwrite /etc/issue? That seems risky.

I recall that we need to ensure the playbook runs on all hosts, but I’m not clear on how to structure the `hosts` line correctly.

I’m a bit confused about the syntax for the `when` condition. Did we use `inventory_hostname` or something else in the examples?

I practiced a similar question where we had to modify a file based on host groups, so I think I can apply that here.

I think I remember needing to use the `copy` module, but I'm not sure if I should use `lineinfile` instead for this task.

I'm pretty sure the answer is C. Activity codes require skillsets to be assigned, right?

Based on my understanding, the "Linux x86 with 64 bit JVM" option is the correct one. The "x86" refers to the processor architecture, and the "64 bit JVM" specifies that it's a 64-bit distribution, which is what we need for our 64-bit Linux system. I'm fairly confident in this answer.
