Options:

Marking/Remarking

Classification

Encapsulation

Scheduling

Answer

Questions # 122:

A physical port has three associated buffer pools. Which of the following buffer pool combinations is associated to a physical port?

Options:

Access ingress, access egress, network egress

Access ingress, network ingress, network egress

Port ingress, port egress, shared bi-directional

Answer

Questions # 123:

To implement Hierarchical-QoS (Multi-tiered scheduling), which of the following actions must be undertaken? (Choose three)

Options:

H-QoS capabilities must be enabled globally on the router

A scheduler-policy must be configured.

The queues in the SAP-ingress and SAP-egress policies do not require additional configuration attributes to make use of the hierarchical schedulers.

The network queue policy must be configured to make use of the scheduler-policy.

The scheduler-policy must be referenced in the SAP-ingress and SAP-egress policies.

The scheduler-policy must be applied on the service SAP.

Answer

B, E, F

Questions # 124:

In a BGP VPLS, which of the following BGP attributes is used to carry the L2 MTU?

Options:

The NRLI

The AFI

The SAFI

The extended community

Answer

Questions # 125:

For what does a Layer 2 switch use the SA in the Ethernet frame?

Options:

MAC learning

SA filtering

Routing table population

Frame forwarding

Answer

Questions # 126:

It is necessary for Tier 1 schedulers to obtain bandwidth from a higher tier scheduler.

Options:

TRUE

FALSE

Answer

Questions # 127:

Packets arrive at the VPRN SAP on PE1 with DSCP marking of all. According to the QoS policies applied at routers PE1, P, and PE2, what is the DSCP value of packets egressing router PE2? (All the SDPs are MPLS-encapsulated, and all interfaces are using their default trust states).

Question # 127

Options:

af11

af12

af31

af33

Answer

Questions # 128:

What is the purpose of the Nokia SR design that includes, for every ingress unicast queue, one hardware queue per destination forwarding complex (FFPC)?

Options:

To utilize memory resources efficiently

To avoid Head of Line blocking

To achieve more granularity of QoS control

To make hierarchical scheduling/policing possible

Answer

Questions # 129:

Which of the following fields in frames belonging to a Layer 3 service CANNOT be marked or remarked on SAP-egress?

Options:

Dotlp

EXP

DSCP

PREC

Answer

Questions # 130:

Which of the following rate-limiting approaches are used on the Alcatel-Lucent 7750 SR? (Choose two)

Options:

Shapeless policing at SAP-ingress only.

Shapeless policing at SAP-ingress and egress.

Biased round robin queuing at ingress only.

Soft shaping at all network interfaces.

Soft shaping at network ingress only.

Answer

D, E

Questions # 131:

Click the exhibit button below. Traffic arriving at router PE 1 is marked with a dot1p value of 4. Given the network policies applied on the routers in the diagram below, what is the EXP value of packets arriving at router PE 2?

Question # 131

Note: Only relevant portions of the network policy are shown.

Options:

None of the above.

Answer

Questions # 132:

What is the maximum number of SAP-ingress policies that can be applied on a SAP?

Options:

Answer

Questions # 133:

Which of the following statements are TRUE when discussing self-generated traffic QoS? (Choose two)

Options:

In order to mark Layer 2 traffic, sgt-qos will set various ToS bits.

DSCP bits can be set per application, per routing instance.

The DSCP marking stays nc1 for all applications. Only the internal FC is manipulated across different applications.

In order to mark Layer 2 self-generated traffic, network interfaces must be set to dot1Q.

The internal forwarding class for self-generated traffic is set once and applied to the base router and all VPRN instances.

Answer

B, D

Questions # 134:

In the image shown above, the network QoS policy is applied properly to a Nokia 77S0 SR acting as a transit Label Switch Router (LSR) for a given MPLS tunnel. A packet is received inside the MPLS tunnel with EXP=5, dotlp=0, and DSCP=EF. Which forwarding class is assigned to this packet?

Question # 134

Options:

Answer

Questions # 135:

In the image shown above, the SAP-ingress policy is applied properly to a Nokia 7750 SR. A traffic stream is received from an IP address of 192.168.1.1 with DSCP set to EF. Which forwarding class and priority level is used for this traffic stream?
