Juniper Exam JN0-664 Topic 1 Question 40 Discussion

Actual exam question for Juniper's JN0-664 exam
Question #: 40
Topic #: 1
[All JN0-664 Questions]

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

Show Suggested Answer Hide Answer
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.

Hmm, I'm not too sure about C being a mechanism for evaluating traffic. Sounds more like a mechanism for actually shaping the traffic. I'll go with B, D, and E.

I think C is for shaping traffic, not evaluating it.

Ha, can you imagine if 'cat videos' was one of the options? That'd really test our understanding of Junos CoS mechanisms. Anyway, I'm confident B, D, and E are the right answers.

You know, if this was a Cisco exam, they'd probably throw in some crazy options like 'routing protocols' and 'packet encapsulation'. Glad Junos keeps it simple with B, D, and E.

I'm not sure about fixed classifiers. I think rewrite rules could also be one of the mechanisms used.

Wait, I thought traffic shapers were used for controlling the bandwidth, not evaluating the traffic for CoS. I'm going with B, D, and E.
