BIngress traffic is stored in CPM queues and egress traffic is stored in IOM queues.

CIt is always stored in CPM queues.

DIt is always stored in IOM queues.

Answer : B

Question 2

Which of the following statements about the default scheduler in the Nokia 7750 SR is TRUE?

AA queue will be serviced as expedited if all of the forwarding classes mapped to it are expedited, regardless of its configured type.

BA queue will be serviced as best-effort if all of the forwarding classes mapped to it are best-effort, regardless of its configured type.

CA queue will be serviced as expedited if at least one of the forwarding classes mapped to it is expedited, regardless of its configured type.

DA queue will be serviced as expedited if its type is configured as expedited, regardless of the forwarding classes mapped to it.

Answer : A

Question 3

What type of unwanted packet drops can the proper configuration of a queue's burst-limit parameter prevent?

APacket drops in the local queue resulting from traffic congestion.

BPacket drops on the downstream nodes resulting from traffic congestion.

CPacket drops in the local queue resulting from traffic bursts.

DPacket drops on the downstream nodes resulting from traffic bursts.

Answer : C

Question 4

If two queues complete for bandwidth in a hierarchical scheduler environment, which parameter is used by their parent scheduler to determine the priority with which each queue can use bandwidth above its committed rate?

Alevel

Bcir-level

Cweight

Dcir-weight

Answer : C

Question 5

When we select the adaptation rule ''min'', how are the operational CIR/PIR rates of a queue calculated?

AThe administrative PIR values are ignored and both operational rates are set to the minimum residual rate allowed by the hardware.

BThe administrative PIR value is ignored and both operational rates are set to the administrative CIR value.

CThey are chosen as the largest multiple of the hardware rate step that is less than or equal to the corresponding CIR/PIR administrative value.

DThey are chosen as the smallest multiple of the hardware rate step that is greater than or equal to the corresponding CIR/PIR administrative value.

Answer : D

Question 6

By default, how does a hybrid port on a Nokia 7750 SR share its allocated buffer space between access and network pools?

AAll buffer space is initially allocated to access pools, and some of it is reallocated to network pools if network interfaces are configured on it.

BAll buffer space is initially allocated to network pools, and some of it is reallocated to access pools if service SAPs are configured on it.

CBuffer space is allocated 50% for access pools and 50% for network pools.

DBuffer space is allocated 25% for access pools and 75% for network pools.

Answer : C
