Questions # 31:

Which of the following self-generated traffic applications is considered “protocol” traffic, as opposed to “management” traffic?

Options:

BGP

Telnet

ICMP

SNMP

Questions # 32:

In which of the following scenarios is the egress port scheduler useful? (Choose two)

Options:

A customer is complaining that his VoIP traffic is being dropped even though it is sending the correct DSCP markings. Packets are not being dropped on ingress.

A customer is complaining that his VoIP traffic is being dropped even though it is sending the correct DSCP markings. Packets are being dropped on ingress.

A commercial builder has requested numerous dot1Q epipes, VPRNs, and VPLS services to a business park and is only paying up to a maximum 200Mbps.

An equipment manufacturer has requested a NULL epipe service that will transparently pass dot1Q between the new location and national headquarters.

Questions # 33:

Which of the following are examples of metrics for QoS?

Options:

Signal degradation, attenuation, line loss

Latency, FIFO, WRED

Delay, jitter, packet loss

SNR, queue depth, latency

Attenuation, dispersion, latency

Questions # 34:

Which of the following about scheduling is TRUE?

Options:

HQoS schedulers cannot be children of an egress port-scheduler.

HQoS schedulers provide a dynamic method of allocating scheduling resources to queues.

HQoS scheduler policies can be applied to an MDA to schedule network ingress traffic.

A scheduler policy applied to multiple SAPs within the same service will result in a single hardware scheduler operating across all SAPs within the service.

Questions # 35:

Packets arrive at the VPLS SAP on PE1 with DSCP marking of af11 and Dot1p of 2. 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 # 35

Options:

af11

af21

af23

af31

Questions # 36:

Question # 36

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 # 37:

Individual application streams are considered microflows, whereas __________ are considered macroflows.

Options:

SAPs

SDPs

Services

Queues

Schedulers

Forwarding classes

Questions # 38:

Which of the following BEST describes a SAP when regarding QoS?

Options:

A point in the network where EXP bits can be mapped to one of eight predefined FCs, each one with its own queue.

A logical point in a service tunnel where all of customer traffic is aggregated.

A point at which the initial classification of customer traffic occurs.

A point in the network where QoS parameters are discarded in favor of lower-level hardware queuing functions, such as LLI (Link Layer Interleave).

A point in the network where traffic flows from multiple different services are queued together, based on forwarding class.

Questions # 39:

According to the SAP-ingress QoS policy shown, which packets have a higher priority to enter queue 2?

Question # 39

Options:

Packets marked with dscp = af33

Packets marked with dot1p = 4

All packets mapped to queue 2 have the same priority to enter this queue.

There are no packets mapped to queue 2.

Questions # 40:

Real-time rate limiting on the service ingress is a feature that performs_____________. Traffic above the defined PIR is ______________.

Options:

Policing, expedited

Metering, marked discard eligible

Marking, marked discard eligible

Policing, discarded

Shaping, discarded
