A is hardware dependent, but isn't that a bit of a drawback?
JO

E is crucial for proper protocol functioning.

Wow, I didn't know policers could cause false alarms!
VA

I disagree, B is too limiting.
AL

A and D are definitely the ones to consider.

I vaguely remember that protocol overhead is important for convergence, but I'm not confident if that directly relates to high availability in this context.

I practiced a question similar to this, and I feel like the processing order of policers is crucial before forwarding decisions are made.

I think control plane policers are mostly important for devices that face the internet, but I can't recall if that's enough for high availability.

I remember something about control plane policers needing to be enforced in hardware, but I'm not sure if that's the best option for high availability.
SE

Hmm, I'm a bit confused about the role of control plane policers in external-facing devices versus internal ones. And the potential for false alarms is an interesting consideration.

Ah, I see. The question is asking about the two most important control plane policer designs to achieve high availability. I'll need to carefully evaluate each option and choose the best two.

I think the key here is considering both the hardware and software aspects of the control plane policers. We need designs that work well across different platforms and don't cause issues with network management.

Okay, let's see. I know control plane policers are important for protecting the software path, but I'm not sure about the hardware platform dependency. And do they really need to be processed before forwarding?
GE

Hmm, this question seems tricky. I'll need to think carefully about the different control plane policer designs and how they impact high availability.

I'm just glad they didn't throw in an option about using control plane policers to stop hackers from stealing my socks. That would have really thrown me off.

D) Control plane policers must be processed before a forwarding decision is made.
LE

A) Control plane policers are enforced in hardware to protect the software path, but they are hardware platform dependent in terms of classification ability.
MY

Hey, at least they didn't ask about the control plane policer's fashion sense. That would have been a tough one!

D) Control plane policers must be processed before a forwarding decision is made.
JA

A) Control plane policers are enforced in hardware to protect the software path, but they are hardware platform dependent in terms of classification ability.
ER

D is just plain wrong. The control plane policer has to be processed before the forwarding decision, not after. It's there to protect the control plane, not the data plane.
TR

E) Control plane policers require that adequate protocols overhead are factored in to allow protocol convergence.
TA

A) Control plane policers are enforced in hardware to protect the software path, but they are hardware platform dependent in terms of classification ability.
YA
Yasuko

I'm not sure about that. I think A and D are the correct answers because control plane policers are hardware dependent and must be processed before forwarding decisions.
NA
Nathan

I'm not sure about B. Shouldn't control plane policers be used on all devices, not just externally facing ones? And C is definitely wrong - false alarms would be a big problem.
SE
Sean

E) Control plane policers require that adequate protocols overhead are factored in to allow protocol convergence.
BE

D) Control plane policers must be processed before a forwarding decision is made.
BI

B) Control plane policers are really needed only on externally facing devices.
EM

A) Control plane policers are enforced in hardware to protect the software path, but they are hardware platform dependent in terms of classification ability.
DO

A and E seem like the right options to me. The control plane policer needs to be hardware-based to protect the software path, and it needs to account for protocol overhead to allow convergence.
KI

I agree with you, Thora. Control plane policers must be processed before forwarding decisions are made, and protocols overhead should be factored in for convergence.
TH
Thora

I think the correct answers are D and E.
