Question: 1

On an Alcatel-Lucent IOM 3, how is buffer memory allocated per forwarding complex?

A512 MB ingress, 512 MB egress

B256 MB ingress, 256 MB egress

C1 GB dynamically allocated between ingress and egress.

D768 MB dynamically allocated between ingress and egress.

E768 MB, with a minimum of 256 MB ingress and egress, and an additional 256 MB dynamically allocated.

Question: 2

When allocating scheduling resources, which of the following statements BEST describes how the egress port scheduler allocates bandwidth?

AThe egress port scheduler takes the ratio of requested bandwidth to total bandwidth request from all children. It allocates bandwidth fairly, using these percentages and not exceeding the egress interface speed.

BThe egress port scheduler allocates bandwidth based on a WRR distribution method that takes into account the CIR and PIR requested at each level and the max speed, either default or configured, on egress.

CThe egress port scheduler allocates bandwidth on a first come, first served distribution method that takes into account the total CIR and PIR requested at each level and the max PIR requested from a single level.

DThe egress port scheduler will limit the bandwidth offered to the egress port based on the over-subscription factor, provisioned under the router interface, while using a WRR scheduler for the remaining bandwidth.

EThe egress port scheduler will use the Russian Dolls Method to allocate bandwidth to each level of requested bandwidth. HPO-Only is automatically set to 100%, allowing only high priority traffic to be buffered during congestion.

q3_4A0-107

AAll incoming packets belonging to forwarding class ''l2'' are stored in the reserved buffer space.

BAll incoming packets belonging to forwarding class ''af'' are stored in the reserved buffer space.

CAll incoming packets belonging to forwarding class ''l1'' are stored in the reserved buffer space.

DIn-profile packets in the shared buffer space are being dropped.

Question: 4

While deciding how to share the available bandwidth among its children, when does a port scheduler consider the parameter ''level'' of a child?

ADuring the allocation of within-CIR bandwidth.

BDuring the allocation of above-CIR bandwidth.

CDuring the allocation of both within-CIR and above-CIR bandwidth.

DThe port scheduler does not use the level of a child for making bandwidth allocation decisions
