Questions 42

Which of the following statements about a queue’s rate parameters is FALSE?

Options:

If CIR = PIR, then all packets will be considered as in-profile.

CIR can be set to 0.

CIR can be larger than PIR.

CIR can be set to ‘max’.

Questions 43

Which of the following is an example of something that CAN be done with hierarchical policing (CFHP) but CANNOT be done with standalone policers?

Options:

Limiting the maximum forwarding rate of each individual policer and, at the same time, marking, packets as in-profile or out-of-profile.

Putting packets in a buffer as they are received, and marking packets as in-profile or out-of-profile as they are removed from the buffer.

Rate-limiting the collective output of several policers, and to reallocate bandwidth that is not utilized by some policers to other policers that need to use it.

Rate-limiting the collective output of several policers towards each egress FFPC, while maintaining control of the maximum overall forwarding rate.

Questions 44

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

Options:

During the allocation of within-CIR bandwidth.

During the allocation of above-CIR bandwidth.

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

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

Questions 45

Which of the following statements regarding egress FC and profile over-ride are TRUE? (Choose two)

Options:

Packets can be classified into 16 different FCs when using priority mode queuing.

This feature is available on egress SAPs within any service.

MPLS EXP bits can be changed based on multi-field classification.

If a Behavior Aggregate (BA) and Multi-field (MF) match occurs, only the MF override parameters will take effect.

If a Behavior Aggregate (BA) and Multi-field (MF) match occurs, the BA classification can override the forwarding class while the MF classification can override the profile.

Questions 46

Which of the following is an advantage of using queue-groups on a service SAP?

Options:

It enables CFHP.

It more scalable than using policers.

It allows a separate set of queues/policers for each VLAN on a port.

It allows a set of queues to be shared among multiple SAPs.

Questions 47

4A0-107 Question 47

According to the SAP-ingress QoS policy shown, what is the maximum amount of memory that queue 5 can use from the shared buffer pool?

Options:

1 kilobyte

2 kilobytes

10 kilobytes

20 kilobytes

Questions 48

Click the exhibit button below. Given the scheduler-policy (below), how much bandwidth can the best-effort traffic receive (PIR and CIR) when the ingress rate of each queue is 10Mbps?

4A0-107 Question 48

Options:

PIR = 4Mbps. CIR = 1Mbps

PIR = 1Mbps, CIR = 1 Mbps

PIR = 10Mbps, CIR = 1Mbps

PIR = 5Mbps, CIR = 1.25Mbps

PIR = 1.25Mbps, CIR = 1.25Mbps

Questions 49

Which of the following egress points does NOT support egress reclassification?

Options:

Spoke-SDPs bound to an IES

Spoke-SDPs bound to a VPRN interface

SAPs

Network interfaces

Questions 50

Options:

ToS

DSCP

PREC

EXP
