QuestionQ3

Class of Service (CoS)

A packet arrives on an interface configured for transmission scheduling. One configured queue exceeds its allocated bandwidth.

In this scenario, which two actions does a Junos device take by default?

Choose two
  • A The exceeding queue will be considered to have negative bandwidth credit.
  • B The excess traffic will be discarded.
  • C The exceeding queue will be considered to have positive bandwidth credit.
  • D The excess traffic will use bandwidth available from other queues.
Explanation

A queue receiving traffic beyond its configured bandwidth allocation has negative bandwidth credit. By default, Junos permits that queue to use leftover bandwidth available from other queues; strict allocation must be explicitly configured to prevent this behavior.
