I thought memcached was outdated? Surprised it's still in use!

Wait, why are we using `--dry-run`? Seems unnecessary.

You only need nginx, redis, and memcached for this task.

I definitely remember using `kubectl run` for creating pods, but I’m not sure if I should use `--dry-run` in this case. I hope I can figure it out during the exam!

I’m a bit confused about whether we need to specify the container names in the YAML. I think we do, but I can't remember if they have to match the image names.

This question feels familiar; I practiced something similar where I had to create a pod with nginx and redis. I hope I can recall the exact commands.

I think I remember that we need to create a pod with multiple containers, but I'm not sure if the syntax for the YAML file is exactly right.

I'm pretty sure TRIZ refers to a set of problem-solving tools, so I'll go with option A.

Hmm, I'm a bit unsure about this one. There are a lot of different scenarios and characters involved. I'll need to carefully read through the details to make sure I don't miss anything important.

I'm pretty confident LACP is the right answer. It allows for load balancing across multiple links, which should reduce latency in the backend.
