8/14/2019 What Two Results Do Network Managers Try

1/5

What two results do network managers try to accomplish with a queuingpolicy? (Choose two.)

provide appropriate service levels for users

lower total bandwidth utilization

control expensive WAN costs

increase network latency

Which of the following uses IP precedence to determine the packets that willbe dropped from a queue?

LLQ

tail drop

WRED

DSCP

Which two statements are true about the best-effort model? (Choose two.)

It is not scalable.

Critical data has special priority .

Traffic is controlled using RSVP.

Packets can arrive out of order.

It is the easiest and quickest model to deploy.

___________________________________________________________________________________

Which statement is true about RSVP?

It can be used with IP and SNA protocols.

It is used by all three QoS models.

It utilizes dynamic ACLs throughout the path.

It is a routing protocol that enables different QoS services to be applied to

different classes.

Which three voice traffic characteristics are affected when QoS tools are enabledon the network? (Choose three.)

sampling rate for the voice packets

bandwidth availability for the voice traffic

analog-to-digital signal conversion


2/5

voice traffic delay

jitter and loss of the voice packets

quantization error and noise of the voice packets

Refer to the exhibit. Which two statements are true? (Choose two.)

Any voice traffic that is marked with precedence 5 and routed to network 10.1.10.0/24 will be given a priority of 100.

Any voice traffic that is either marked with precedence 5 or routed to network10.1.10.0 /24 will be given a default priority.

Any application traffic that is routed to both host 10.1.10.20 and host 10.1.10.49will have 25% guaranteed bandwidth.

The traffic that is classified in the class-default class will have 75% guaranteedbandwidth.

Any voice traffic that is marked with precedence 5 or routed to network10.1.10.0 /24 will be given a priority of 100.

__________________________________________________________________________________-

Refer to the exhibit. How are the bandwidth percentage values determined for theQoS wizard?

They are populated by NBAR.

They are provided by the administrator.

They are determined based upon the bandwidth of the interfaces involved.

They are based upon the quantity of hosts on the network._____________________________________________________________________________

Refer to the exhibit. What three classes of traffic are included in class1?(Choose three.)


3/5

all IP packets with destination MAC address 1.1.1

all packets with destination MAC address 1.1.1

all packets defined by qos-group 3

all packets in access-group 2

all packets in class2 with destination MAC address 1.1.1

all packets in access-group 2 with destination MAC address 1.1.1

Refer to the exhibit. Which statement is true about the configuration?

No traffic will be matched against this class map.

All traffic will be processed FIFO.

All traffic will be matched except IP traffic.

All traffic will be processed and use the default QoS that is applied to that

policy.

Refer to the exhibit. A network administrator was troubleshooting a new QoSconfiguration that was intended to limit IP protocol traffic. The configurationdoes not appear to be working properly. On the basis of the configuration that isshown, what traffic is being included by this class map?

No traffic will be matched against this class map.

All traffic will be matched except IP traffic.

All traffic will be processed using the default QoS applied to that policy.

All traffic will be matched.

What are the three classes of traffic that are identified by default by theSecurity Device Manager (SDM) QoS wizard? (Choose three.)

scavenger

real-time

business-critical

best-effort

FIFO

priority

A queuing policy helps the network manager meet which two major challenges?(Choose two.)


4/5

controls bursty LAN traffic

provides an appropriate level of service for all users

improves network security

controls expensive WAN costs

Refer to the exhibit. What three Security and Device Manager (SDM) statisticparameters are available in the drop down that change how the graph is displayed?(Choose three.)

packetization rate

bandwidth

bytes

clock rate

packets dropped

packets processed

Which statement is true about QoS policies?

Each traffic class must have the same QoS policy.

A traffic class assigned an IP precedence of 1 will have the highest priority.

A minimum and maximum bandwidth must be set for each traffic class.

Traffic classified as scavenger will have a higher priority than traffic

classified as transactional.

A traffic class assigned an IP precedence of 5 will have the highest priority.

What is the first action that is performed on data by QoS?

identify traffic

classify traffic

mark traffic

enable traffic classes

When Cisco AutoQoS is enabled for a WAN interface, which two functions areperformed? (Choose two.)


5/5

enables NBAR for different traffic types

provides SNMP and syslog alerts for VoIP packet drops

modifies queue sizes and weights where required

provisions LLQ for the VoIP bearer and bandwidth guarantees for control traffic

configures queue admission criteria (maps class of service [CoS] values inincoming packets to the appropriate queues)

Refer to the exhibit. What traffic is classified by this class map?

only Citrix packets in access-group 101

only Citrix packets

only packets in access-group 101

any Citrix packet or any packet in access-group 101

any non-Citrix packet outside access-group 101

any Citrix packet that also matches access-group 101
