* Reviewing POE Interface Information:
* The exhibit shows the output of show poe interface and show poe controller commands.
* The show poe interface command provides information about the PoE (Power over Ethernet) status on each interface.
* Maximum Wattage Allocation:
* The show poe controller output indicates that the maximum power available is 100 watts:

* Thus, statement A is correct.
* Power Consumption and Interface Priority:
* The interface ge-0/0/11 has a high priority with a max power of 25.4W and current consumption of 11.4W:

ge-0/0/11 Enabled ON 25.4W(L) High 11.4W 4
* Given its high priority, ge-0/0/11 will continue to receive power even if the total power consumption exceeds 90 watts, as high-priority interfaces are less likely to be powered off when resources are low.
* POE Status on Interfaces:
* The ge-0/0/0 interface is shown as Enabled OFF, indicating PoE is not currently enabled.

* PoE+ Support:
* The ge-0/0/10 interface has a power class of 4, which indicates support for PoE+.

* Enabling LLDP-MED:
* LLDP-MED (Link Layer Discovery Protocol - Media Endpoint Discovery) is an extension of LLDP specifically for VoIP devices.
* It allows network devices to advertise and receive configuration information, such as VLAN IDs, from the network switch.
* Voice VLAN Feature:
* The voice VLAN feature on switches is designed to simplify the deployment of VoIP by automatically placing voice traffic on a designated VLAN.
* Configuring the appropriate access interfaces and VLAN ID for voice traffic ensures that voice
* packets are prioritized and properly segmented from other types of traffic.
* Configuration Steps:
* Enable LLDP-MED on the appropriate access interfaces:

Junos OS supports both underlay and ingress replication for BUM (Broadcast, Unknown unicast, and Multicast) traffic forwarding in EVPN-VXLAN deployments. Ingress replication is used for efficient multicast traffic distribution in networks where underlay multicast is not available.
