How is voice traffic prioritized correctly on AOS-CX switches?
Voice traffic is best prioritized on AOS-CX switches by placing it in the strict priority queue. This approach ensures that voice packets, which are sensitive to delays, are handled with the highest priority, minimizing latency and jitter. While implementing voice VLANs can help by tagging voice traffic and potentially elevating its priority, the strict priority queue mechanism is a more direct and effective method for ensuring that voice traffic receives the highest level of priority.
I think the answer is B because in Strict Priority (SP) we can put VOIP traffic in top priority (priority 7)
just wondering what is the point to have voice key word under vlan interface then? give you this option, there is a reason. though you can achieve in multiple ways, but most optimized option is C
I think they ask us about something else. With SP we can put priority at any traffic. But they want us to know that turning on voice vlan will put voice vlan in a higher priority. Thats why the answer i think should be C
B is correct. The qos priority default setting is 0 (normal), with 1 as the lowest priority and 7 as the highest priority. If you configure a voice VLAN with a VID of 10, and want the highest priority for all traffic on this VLAN, execute the following commands: HP Switch(config) #: vlan 10 qos priority 7 HP Switch (config) #: write memory
I think the answer is B because in Strict Priority (SP) we can put VOIP traffic in top priority (priority 7)
By tagging the port as voice (Alt C) the switch will by default honor whatever priority the end device uses. This can be changed if needed.
B" voice traffic can be prioritized correctly on an Aruba AOS-CX switch by placing it in the strict priority queue. The strict priority queue is a QoS mechanism that gives the highest priority to specific types of traffic, such as voice or real-time communication traffic. Here's how you can achieve this: Enable Strict Priority Queue: Configure the AOS-CX switch to support strict priority queuing. This ensures that traffic assigned to the strict priority queue will be given the highest priority and processed before other queues.
the correct Answer is C
The question is how is voice traffic prioritized *correctly*. I'm positive they are looking for the VLAN "voice"-command, even though a manual SP could give it a higher priority.
In the student guide vol.2 on page 267 it is stated , that you enable voice VLAN with a command in the vlan configuration context.
C is Correct
Page 868-869 Study Guide
"Sensitive traffic like VOIP uses Strict Priority queuing " B is correct
I hate this kind of question because different option are possible. We can use answer A because a device profile can assign QoS to voice traffic come from IP Phone, but i think it is not the "correctly" way to prioritize Voice traffic. We can use answer B because we can assigne voice traffic to high queue with strict priority but i think again this is not the best way to prioritize voice traffic. We can use answer C because best way to prioritize voice traffic is to enable voice vlan but not only, we need to trust DSCP/CoS or remark then prioritize... So I vote for C but not sure...
