20+ practice questions focused on IP Telephony Features — one of the most tested topics on the Juniper Networks Enterprise Routing and Switching, Professional (JNCIP-ENT, JN0-650) (JNCIP-ENT) exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start IP Telephony Features PracticeAn administrator notices that an EX4300 switch is supplying power using LLDP-MED power negotiation, but the IP phone is drawing more power than the initial hardware class allows. Where would you check the advertised LLDP-MED TLV power value received from the phone?
Explanation: The show lldp neighbor interface command displays detailed TLVs received from connected LLDP-MED endpoints, including power requirements.
Which command allows you to verify the real-time PoE power consumption, allocated wattage, and operational status of all interfaces on an EX Series switch?
Explanation: The show poe interface operational command displays detailed power metrics per port.
You are configuring a voice VLAN on an EX Series switch access port where an IP phone is connected in series with a PC. Which configuration is required on the switch interface to handle both tagged voice traffic and untagged data traffic?
Explanation: On an EX Series switch, an access port configured with both 'voice-vlan' and 'native-vlan' parameters can handle tagged voice traffic (on the voice VLAN) and untagged data traffic (on the native/access VLAN). The 'voice-vlan' statement enables the port to recognize and tag voice frames, while the native VLAN handles untagged data frames from the daisy-chained PC. This is the required configuration for IP phone + PC on a single access port.
An EX3400 switch experiences a total PoE power budget exhaustion after multiple high-power IP phones and security cameras are plugged in. You want to ensure that if a power deficit occurs, the switch immediately cuts power to lower-priority ports while maintaining power to executive phones on specific ports. How should you configure this?
Explanation: Priority-based PoE allocation allows administrators to assign priorities (high, low, medium) to specific interfaces to dictate shedding order.
What is the default behavior of an EX Series switch when an LLDP-MED capable IP phone connects and requests a network policy for voice VLAN?
Explanation: LLDP-MED automatically provisions network policies to capable endpoints when properly configured on the switch.
