質問 # 26
You have configured class mode power management on an EX4300 to provide PoE power to telephone and security camera equipment. You want to ensure that security camera power takes priority over telephone power.
Which two actions would solve this problem? (Choose two.)

A. Set the maximum power settings on ports connected to security cameras.
B. Set the power priority to high on ports connected to security cameras.
C. Connect the security cameras to the lowest port numbers on the switch.
D. Set the power priority to low on ports connected to security cameras.

正解：B、C

解説：
https://www.juniper.net/documentation//en_US/junos/topics/concept/poe-overview.html#jd0e1522 Thus you must set interfaces that connect to critical powered devices, such as security cameras and emergency phones, to high priority. Among PoE interfaces that have the same assigned priority, power priority is determined by the port number, with lower-numbered ports having higher priority.

質問 # 35
A user is attempting to watch a high-definition video being streamed from the media server over the network. However, the user complains that the experienced video quality is poor. While logged on to router B, a Juniper Networks device, you notice that video packets are being dropped.
In this scenario, what would solve this problem?

A. Adjust the expedited-forwarding BA classifier to router B's ge-0/0/0 interface to support a higher transmit rate.
B. Adjust the scheduler-map to support a higher transmit rate.
C. Adjust the expedited-forwarding BA classifier on router B's ge-0/0/1 interface to support a higher transmit rate.
D. Adjust the scheduler for the expedited-forwarding forwarding class to support a higher transmit rate.

正解：D

解説：
transmit rate is set on the scheduler, BA and classifier do not have transmit rate. scheduler-map=maps schedulers to fwd classes
