Juniper Enterprise Routing and Switching, Professional (JNCIP ENT)

An emergency Class 3 IP phone is connected to an EX Series switch. You want to ensure that the IP phone does not have any problems if PoE power demands on the switch are greater than the PoE power budget.  What should you do to accomplish this task?

You are implementing PoE on your EX Series switch to provide power to your VoIP phones. You have a device that does not provide its class information to the switch. Which power class is assigned for this device?

NetBIOS snooping information is stored in which database on EX Series switches?

You are asked to implement CoS on an EX Series switch. You attempt to configure the priority for the voice and data queue schedulers to medium-high and medium-low priority, respectively. However, you notice that the only parameters available for the priority is strict high and low. Why are strict high and low the only available parameters for configuration?

You are asked to configure a CoS weighted tail drop profile on your EX Series switch that causes all traffic in the best effort queue to drop when the queue is 90 percent full. Which configuration will accomplish this request?

You must configure a multifield classifier on ge-1/0/0. This classifier must match only TCP traffic from port number 79, set the loss priority to high, and classify the traffic as expedited-forwarding. The inbound traffic has no previous CoS markings. Which configuration meets these requirements?

You are asked to reconfigure a CoS scheduler to limit the assured forwarding queue to a maximum of 75 percent of the available bandwidth. The assured forwarding queue uses a strict high priority queue. Which configuration parameter accomplishes this task?

You are asked to configure an interface policer. You must ensure when the bandwidth limit and burst size are exceeded, that the packet receives a CoS parameter which increases the probability that the packet will be dropped if the queues are congested. Which policer action will accomplish this requirement?

You must troubleshoot a CoS issue on an Ethernet interface which has been observed to drop packets in the best effort queue. You must determine whether the dropped packets are tail drops. Which CLI command output accomplishes this task?

You are asked to establish a single EBGP peering across two physical interfaces to your ISP. Which BGP feature should you use?
