Question #: 22
Topic #: 1

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 .

I'm going to have to go with D on this one. 6 is the highest priority, and we all know voice is the king of network traffic, so it deserves the royal treatment!

I also believe class 6 is the best choice for voice data, it needs to be prioritized.

I'm not sure, but I think class 0 might be too low of a priority for voice data.

I think class 4 would be sufficient for voice data, it doesn't need the highest priority.

Wow, this is a tough one. I'm gonna go with C just because it sounds the most professional. Plus, 4 is a nice, even number. What could go wrong?

A, definitely. 0 is the default best-effort class, and that's perfect for voice data. Who needs priority, am I right?

B is the way to go. 2 is the standard priority for real-time traffic like voice, so that's the logical choice here.
