A company has a Unified Communications and Collaboration (UCC) solution.
✑ Users run softphones on their desktops and laptops.
✑ The UCC solution is configured to use a certain range of Layer 4 ports for VoIP traffic.
✑ The user devices connect to AOS-Switches.
A network administrator needs to configure the AOS-Switches to prioritize only the VoIP traffic. Where can the administrator configure a DSCP value to meet this goal?
To prioritize VoIP traffic, the network administrator should configure the DSCP value on the interfaces that connect to the user devices. This ensures that VoIP traffic is marked as high priority as soon as it enters the network, allowing it to be treated with higher precedence throughout its journey. Setting it at the ingress point (where the traffic first enters the switch) is essential for proper traffic classification and prioritization across the network.
I think correct answers is A
Yes, the correct answer is A. switch(config)#qos <tcp-port | udp-port> range <first port> <last port> {priority <0-7> | dscp <codepoint>}
The coorect answer is B. on the interfaces through which the VoIP traffic is forwarded. ex: interface 1/1 qos dscp ef
Marking should be done as close to the source as possible. So answer should be C! Because this is the place where the traffic comes in and thereby it should be marked here.
Corecct is A
C or D It needs te be set on inbound interface to forward with Priority, Setting on the vlan would be my choice. To set at the port, we can adjust that at the vlan either by changing the queue weights or assigning all traffic on the vlan to a specific priority, like the command I shared earlier "qos priority #" or you can set by DSCP "qos dscp <value>" in the vlan.
