   An administrator is troubleshooting a voice VLAN issue on an OS6 switch. The IP phones are not receiving the voice VLAN information via LLDP-MED. The administrator has verified that LLDP is enabled globally and on the interfaces. Which additional check should the administrator perform to isolate the problem?

   • AVerify that the switch is advertising the voice VLAN via LLDP-MED using 'show lldp med local interface'.
   • BVerify that the phone is connected to the correct port and that the port is up using 'show interfaces status'.
   • CVerify that the voice VLAN exists in the VLAN database using 'show vlan'.
   • DVerify that the voice VLAN is configured on the correct interface using 'show interfaces switchport'.

   Which benefit is directly achieved by placing IP phones in a dedicated Voice VLAN?

   • AVoice traffic can be prioritized with QoS policies without affecting data traffic.
   • BThe switch can automatically power IP phones without PoE configuration.
   • CIP phones can use the same IP subnet as PCs, reducing IP address consumption.
   • DVoice traffic is encrypted by default, ensuring call privacy.

   A network team is planning to deploy IP phones on an OS6 switch. They want to ensure that voice traffic is not affected by data traffic broadcasts and that QoS can be applied to voice. They also want to verify the configuration after implementation. What is the primary benefit of using a voice VLAN in this scenario?

   • AIt reduces the number of VLANs required on the switch.
   • BIt allows the switch to route voice traffic between subnets without a router.
   • CIt enables the IP phone to use the same IP subnet as the PC.
   • DIt isolates voice traffic into a separate broadcast domain, allowing QoS and security policies to be applied specifically to voice.

   A company is deploying IP phones and PCs on the same access ports of an OS6 switch. The network team wants to ensure that voice traffic is prioritized and isolated from data traffic to maintain call quality. What is the primary reason for configuring a separate voice VLAN on the switch?

   • ATo allow the IP phone to obtain an IP address from a different DHCP server than the PC.
   • BTo enable the switch to route voice traffic between different subnets without a router.
   • CTo separate voice and data traffic into different broadcast domains, enabling QoS policies to prioritize voice.
   • DTo reduce the number of VLANs required on the network by combining voice and data on the same VLAN.
