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 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...
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.
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
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.
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
