Refer to the exhibits.
In the exhibits, what is the reason for the tail drops in queue 0?
A.
The interface cannot physically handle 3.37 Gbps of traffic.
B.
The default network-control scheduler is taking bandwidth from the best-effort scheduler.
C.
The default queue 0 scheduler does not allocate enough buffer size for 3.37 Gbps of traffic.
D.
The default queue 0 scheduler does not allocate enough transmit rate for 3.37 Gbps of traffic.
Explanation:
How is this determined?

Te answer is C because the device uses the default scheduler settings:
[edit class-of-service]
schedulers {
network-control {
transmit-rate percent 5;
buffer-size percent 5;
priority low;
drop-profile-map loss-priority any protocol any drop-profile terminal;
}
best-effort {
transmit-rate percent 95;
buffer-size percent 95;
priority low;
drop-profile-map loss-priority any protocol any drop-profile terminal;
}
}
drop-profiles {
terminal {
fill-level 100 drop-probability 100;
}
}

the default scheduler that BE have 95% buffer-size
