You recently deployed an SRX Series Gateway in your network. It uses the default class of
service configuration.
Based on the output in the exhibit, what reason explains the packet drops in Queue 1?
A.
Interface ge-0/0/0 should be used only for management network operations.
B.
Queue 0 has higher priority than Queue 1.
C.
A policer is reclassifying all traffic into Queue 1.
D.
No bandwidth reservation exists on Queue 1.
Can someone explain?
Even if there is bandwidth reservation I have no idea how much bandwidth was reserved = I can still have dropped packets.
More reasonable explanation in this output is for me the different priority of Q0.

I found it…
Queue 0 has reserved 95% of the bandwidth and queue 3 has reserved 5% of the bandwidth with no traffic reservations for queue 1. This is the default Junos OS configuration for every interface.
