Question 5

Which of the following is an example of something that CAN be done with hierarchical policing (CFHP) but CANNOT be done with standalone policers?

ALimiting the maximum forwarding rate of each individual policer and, at the same time, marking, packets as in-profile or out-of-profile.

BPutting packets in a buffer as they are received, and marking packets as in-profile or out-of-profile as they are removed from the buffer.

CRate-limiting the collective output of several policers, and to reallocate bandwidth that is not utilized by some policers to other policers that need to use it.

DRate-limiting the collective output of several policers towards each egress FFPC, while maintaining control of the maximum overall forwarding rate.

Answer : A

Question 6

What is an SLA? (Choose two)

AAn SLA is used to provide automated, real-time testing and alarming for throughput, latency, and jitter across a provider's network.

BAn SLA is an agreement between a customer and a provider that dictates the treatment of customer traffic across the provider's network.

CAn SLA allows customers to control all traffic within the service provider's network by prioritizing their traffic over others as desired.

DAn SLA allows a customer to pre-mark traffic and ensure that traffic is treated as per the agreement within the provider's network.

EAn SLA is a standard set of network QoS policies that a provider shares to all its customers, allowing them to better understand the treatment of traffic within the provider's network.

Answer : B, D

BPackets in forwarding classes 'be' and '12' are being queued.

CTraffic belonging to forwarding class 'ef' is not experiencing queuing delays.

DTraffic belonging to forwarding class '11 'will never make use of the shared buffer pool.

EOut-of-profile traffic in the shared buffer pool is being dropped.
