JN0-649 Exam - Question 38


Your EX Series switch has IP telephones and computers connected to a single switch port. You are considering implementing the voice VLAN feature to help with this setup.

In this scenario, which two statements are correct? (Choose two.)

Show Answer
Correct Answer: CD

Assigning the incoming voice and data traffic to separate VLANs enables the ability to prioritize the traffic using CoS. This allows for better management and quality of service for voice traffic, which is often more sensitive to delays and requires higher priority. Additionally, the voice VLAN feature allows incoming tagged data and voice traffic to be associated with separate VLANs, ensuring that voice and data traffic do not interfere with each other and can be managed more effectively.

EX Series switches can accommodate an IP telephone and end host connected to a single switch port. In such a scenario, voice and data traffic must be separated into different broadcast domains, or VLANs. One method for accomplishing this is by configuring a voice VLAN, which enables access ports to accept untagged data traffic as well as tagged voice traffic from IP phones, and associate each type of traffic with separate and distinct VLANs. Voice traffic (tagged) can then be treated differently, generally with a higher priority than data traffic (untagged)
