Discuss Juniper JN0-664 Exam Topic 7 Question 24

Which three mechanisms are used by Junos platforms to evaluate incoming traffic for CoS purposes? (Choose three )

Arewrite rules

Bbehavior aggregate classifiers

Ctraffic shapers

Dfixed classifiers

Emultifield classifiers

Suggested Answer: B, D, E

Junos platforms use different mechanisms to evaluate incoming traffic for CoS purposes, such as:

Behavior aggregate classifiers: These classifiers use a single field in a packet header to classify traffic into different forwarding classes and loss priorities based on predefined or user-defined values.

Fixed classifiers: These classifiers use a fixed field in a packet header to classify traffic into different forwarding classes and loss priorities based on predefined values.

Multifield classifiers: These classifiers use multiple fields in a packet header to classify traffic into different forwarding classes and loss priorities based on user-defined values and filters.

Rewrite rules and traffic shapers are not used to evaluate incoming traffic for CoS purposes, but rather to modify or shape outgoing traffic based on CoS policies.

Pretty sure fixed classifiers are outdated now.

Darell 11 months ago

Wait, I didn't know multifield classifiers were a thing!

Marti 11 months ago

A and D are not used for CoS, just FYI.

Jamal 11 months ago

I thought traffic shapers were part of it too?

Alaine 12 months ago

Definitely A, B, and E!

Kenda 12 months ago

I practiced a similar question, and I think the answer might include fixed classifiers and multifield classifiers for sure.

I feel like multifield classifiers are a key part of CoS evaluation, but I might be mixing it up with traffic shapers.

Charlene 1 year ago

I remember studying behavior aggregate classifiers, but I can't recall if rewrite rules were mentioned in the same context.

Willard 1 year ago

I think the fixed classifiers are definitely one of the mechanisms, but I'm not sure about the others.

Teri 1 year ago

Traffic shapers? I'm not sure how that fits into CoS evaluation. I'll need to double-check the details on that one.

Shawnda 1 year ago

Rewrite rules, behavior aggregate classifiers, and multifield classifiers - got it. I think I've got a good handle on the key CoS evaluation mechanisms on Junos.

Noel 1 year ago

Okay, let's think this through step-by-step. I know behavior aggregate classifiers and multifield classifiers are two of the key mechanisms, so I'll start there.

Mabel 1 year ago

Hmm, I'm not too sure about the differences between the various classifier types. I'll need to review those concepts again.

Brunilda 1 year ago

This looks like a pretty straightforward CoS question. I'm confident I can handle this one.

Aileen 1 year ago

Hmm, I'm a bit unsure about this one. The options seem to cover different aspects of the test plan, but I'm not sure which one is the main purpose. I'll have to think this through carefully.

I remember there being a question on the TelePresence Recording Server in practice, but I can't recall if that's the one we're looking for here.

Derrick 1 year ago

I'm a little confused on this one. Is user ID and password considered physical, technical, or administrative access control? I'll have to review my notes.

Gabriele 1 year ago

Hmm, I'm a little unsure here. The question and solution don't seem to line up perfectly. I think I'll review the material one more time before answering, just to make sure I have the right approach.

Chauncey 1 year ago

Hmm, I'm a bit confused here. The question mentions that all the data must be available locally, but some of the AWS options like S3 and Glacier are cloud-based storage. I'll need to think this through carefully to make sure I understand the requirements fully.

Capital gain calculation seems complex here. Need to consider indexed cost of acquisition and transfer date specifics.
