I think etcd is related to storing configuration data, but I'm not entirely sure if it's specifically for the Kubernetes API.

The key is to focus on the specific capabilities of RMAN. I think options A, B, and F are the most straightforward ones to identify as true.

Hmm, I'm a little unsure about the details here. I know label selectors are used to select pods, but I'm not totally clear on all the nuances. I'll have to think this through carefully.

Wait, I thought $addToSet was just a deprecated version of $push. Are they actually different? I'm not sure, but I'll try to reason through the options and see if I can figure it out.
