A network operator wants to make sure voice data is prioritized.

In this scenario, to which Ethernet traffic class should it be assigned.

Show Suggested Answer

Suggested Answer: D

A network operator who wants to make sure voice data is prioritized should assign it to Ethernet traffic class 6. Ethernet traffic class is a term used to refer to the priority code point (PCP) field in the VLAN header of an Ethernet frame. The PCP field is a 3-bit field that can encode up to eight different priority levels, ranging from 0 (lowest) to 7 (highest). The PCP values can be mapped to different types of traffic according to their QoS requirements. The recommended mapping is as follows :

PCP 0: Best effort (default)

PCP 1: Background

PCP 2: Spare

PCP 3: Excellent effort

PCP 4: Controlled load

PCP 5: Video

PCP 6: Voice

PCP 7: Network control

Voice data is a type of real-time traffic that requires the highest priority and lowest delay in the network. Therefore, it should be assigned to PCP 6, which corresponds to Ethernet traffic class 6 .

Class 2 is too low for voice prioritization!

I believe class 4 is for voice, but I might be mixing it up with video traffic.

I’m a bit confused; I thought class 2 was for voice, but now I’m second-guessing myself.

I remember practicing a similar question, and I think voice traffic is usually prioritized in class 6.

I think voice data should be assigned to a higher traffic class, but I’m not sure if it’s 4 or 6.

I'm pretty confident the answer is D. Voice data should be assigned to the highest Ethernet traffic class, which is 6, to ensure it gets the highest priority.

Okay, let's see. Voice data needs to be prioritized, so it should be assigned to the highest Ethernet traffic class, which is 4. That's my best guess.

Hmm, I'm not sure about this one. I know voice data needs to be prioritized, but I'm not sure which Ethernet traffic class is the right one. I'll have to think this through carefully.
