A. A packet is accepted into a queue based on its priority and forwarding class.

B. Both high priority-only buffer space and WRED can be used in a queue.

C. Buffer admission control limits the number of out-of-profile packets that enter the queue.

D. Priority is used when a packet enters a SAP-ingress queue.

A. The root arbiter can be the parent of a tier 2 arbiter.

B. Weight is used by a parent arbiter to allocate bandwidth among children of equal level

C. A child policer can have a priority level from 0 to 10.

A. A point in the network where QoS parameters are discarded in favor of lower-level hardware queuing functions, such as LLI (Link Layer Interleave).

B. A point in the network where traffic flows from multiple different services are queued together, based on forwarding class.

C. A point in the network where EXP bits can be mapped to one of eight predefined FCs, each one with its own queue.

D. A logical point in a service tunnel where all of customer traffic is aggregated.

E. A point at which the initial classification of customer traffic occurs.

A. The EXP bits are set on the first network egress, based on a combination of the SAP-ingress classification and the network policy applied.

B. The EXP bits are set based on a default map that translates DSCP codes into internal forwarding classes on SAP-ingress.

C. The first 3 bits of the DSCP value are copied directly into the EXP field on the first network egress.

D. The 3 priority bits are copied directly from the dot1p header into the EXP field of the first MPLS header.

A. The three most significant (first) bits define 8 forwarding classes.

B. To convert DSCP to IP precedence, the three most significant (first) bits are matched.

C. The three least significant (last) bits of the DSCP specify the drop probability.

D. The full 8 bits of the TOS field are used for DSCP.

E. DSCP provides for eight drop probabilities.

A. The dot1p bits in the frame header.

B. The packet's source and destination IP addresses.

C. The service ID of the service to which the SAP belongs.

D. The packet's Ethertype.

E. The EXP bits in the MPLS header.

A. FALSE

B. TRUE
