B . The exceeding queue will be considered to have negative bandwidth credit.
C . The excess traffic will use bandwidth available from other queueses
D . The exceeding queue will be considered to have positive bandwidth credit

Answer: A,C

Explanation:

In Junos devices, when a packet is received on an interface configured with transmission scheduling, and one of the configured queues is exceeding its allocated bandwidth, the typical actions taken are based on the scheduling configuration and congestion management mechanisms in place. Here are the two likely default actions:

The excess traffic will be discarded. When a queue exceeds its configured bandwidth, and if there are no other congestion management mechanisms in place (like buffer or RED profiles), the excess traffic could be dropped by default.

The excess traffic will use bandwidth available from other queues. If excess bandwidth is available from other queues and the scheduling configuration allows for it, excess traffic may utilize unused bandwidth from other queues. This is typical behavior in scenarios where queues are configured with some form of shared bandwidth allocation or where one queue can borrow unused bandwidth from others.
