Yeah, service mesh handles the traffic with sidecars.

I thought "Deployment" was more about managing the lifecycle of applications rather than handling network traffic. Not sure if that's right, though.

I feel like we covered this in class, and "Service mesh" was definitely mentioned as a way to manage communication between pods.

I remember something about sidecar proxies, but I can't recall if it was specifically related to "Network policy" or "Service mesh."

I think the answer might be "Service mesh," but I'm not completely sure. It sounds familiar from our last practice session.

Okay, I've got a strategy for this. I'll focus on the key details about managing communication and injecting a sidecar proxy.

Hmm, I'm a bit unsure about this. I remember learning about DMRS and Sounding RS, but I can't recall if they're both part of the uplink pilot signal in LTE. I'll have to think this through carefully.

No problem, I've done this before. The key is to make sure you have the right key vault and key selected. Once you've got that set up, the rest should be pretty straightforward.

D) Service mesh, for sure. It's like the traffic cop for your pod network, making sure everything gets where it needs to go.

Haha, I bet the correct answer is D) Service mesh. Ain't no way it's A) namespace or E) Service - those are way too basic for this kind of question!

I was thinking it might be B) Deployment, but that's more for managing the lifecycle of pods, not the network traffic. D) Service mesh makes more sense.
