Question No: 11

MultipleChoice

On the Alcatel-Lucent 7750 SR, where can network-queue policies be applied? (Choose two)

Options

AOn the network egress port.

BOn the SDP.

COn the access ingress port.

DOn the egress MDA.

EOn the SAP.

FOn the ingress MDA.

Question No: 12

MultipleChoice

Which of the following statements describe the primary objectives of the policing of traffic flows on the Alcatel-Lucent 7750 SR? (Choose two)

Options

AEnsure that traffic flows conform to their traffic profile.

BLog violations of metered traffic flows exceeding the CIR value set on the entity across which the traffic is moving.

CProvide fairness between traffic flows, so that conforming (in-profile) traffic flows are not starved of bandwidth and/or buffer space by non-conforming (out-of-profile) flows.

DMinimize packet loss and reduce end to end latency.

EEnsure that variable latencies do not cluster short bursts of originally conforming packets and render them nonconforming.

Question No: 13

MultipleChoice

On the Alcatel-Lucent 7750 SR, which of the following QoS-related policies can be configured on a SAP? (Choose three)

Options

AThe slope-policy

BThe SAP-ingress policy

CThe SAP-egress policy

DThe network-queue policy

EThe scheduler-policy

Question No: 14

MultipleChoice

A service provider is using GRE for his transport tunnel on the Alcatel-Lucent 7750 SR. How can traffic be marked as it traverses the service provider's network? (Choose two)

Options

AUsing dot1p bits of the 802.1q Ethernet frame header

BUsing DSCP bits within the ToS field of the IP packet header.

CUsing the IP precedence bits within the ToS field of the IP packet header.

DUsing the CLP bit of the ATM cell header.

EUsing the EXP bits of the MPLS transport label header.

Question No: 15

MultipleChoice

At which points can traffic be marked or remarked on the Alcatel-Lucent 7750? (Choose two)

Options

ASAP-ingress only

BSAP-egress only

CSAP-ingress and SAP-egress

DNetwork ingress

ENetwork egress

Question No: 16

MultipleChoice

Which of the following statements regarding policing and shaping on the Alcatel-Lucent 7750 SR are TRUE? (Choose two)

Options

AThe larger the configured MBS value, the lower the amount of shaping performed.

BWhen policing is enabled on the SAP-ingress, all traffic is considered as in-profile.

CSetting the CIR to 1000 and the PIR to max will enable shapeless policing at 1 Mbps within the SAP-egress policy.

DConfiguring MBS to equal CBS will disable shaping.

ESetting the CIR and PIR to equal values disables soft-policing.

Question No: 17

MultipleChoice

Which of the following are possible criteria for classifying packets at the network port ingress on the Alcatel-Lucent 7750 SR? (Choose three)

Options

AThe EXP bits in the MPLS header.

BThe packet's source and destination IP addresses.

CThe packet's DSCP bits.

DThe dot1p bits in the frame header.

EThe ID of an SDP that is transporting the packet.

Question No: 18

MultipleChoice

Which of the following are major components of QoS functionality on the Alcatel-Lucent 7750 SR? (Choose three)

Options

AMicroflow reservations using RSVP

BDSCP to EXP translation

CTraffic classification

DAutomatic profiling and policy configuration

EBuffer memory management

FTraffic scheduling

Question No: 19

MultipleChoice

What can be learned from the output of the command ''show pools 1/2/2 network-egress'' on the GigE port?

Options

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 No: 20

MultipleChoice

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

Options

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
