A. B. C. D.A
A scheduler is a Junos OS feature that controls the order in which packets are transmitted from a queue. It allows you to allocate bandwidth to different classes of traffic, prioritize certain types of traffic, and control how the queue is serviced. A scheduler is applied to an interface or logical interface to manage the flow of traffic.
The contents of a scheduler are the parameters that define how a queue should be serviced. These parameters include the scheduling algorithm used, the maximum transmission rate, and the priority assigned to each forwarding class. There are several types of scheduling algorithms, including strict priority, weighted fair queuing, and deficit round robin.
Option A is correct because a scheduler contains parameters that describe how a queue should be serviced. These parameters are used to determine the order in which packets are transmitted from the queue and how much bandwidth is allocated to each forwarding class.
Option B is incorrect because a scheduler does not contain traffic that is ready to be transmitted. Rather, it manages the transmission of packets from a queue.
Option C is incorrect because a scheduler does not contain forwarding classes. Instead, it assigns priorities to forwarding classes and uses these priorities to determine how packets are transmitted from the queue.
Option D is incorrect because a scheduler does not contain a map between the classification of a packet and its forwarding class. However, it does use the classification of a packet to determine which forwarding class to assign it to based on the configured rules and priorities.
In summary, the correct answer is A. A scheduler contains parameters that describe how a queue should be serviced.
