Refer to the exhibit. Why does the trust state of interface FastEthernet 0/3 show “not
trusted”?

Refer to the exhibit. Which statement is true when voice traffic is forwarded on the same
VLAN used by the data traffic?

Refer to the exhibit. A trunk link is connected between switch A_SW and switch D_SW.
Based on the configuration shown in the exhibit, how would the traffic coming from the
switch A_SW be managed?

Jitter is causing problems with the VOIP application in the Company network. What causes
network jitter?
Variable queue delays
Packet drops
Transmitting too many small packets
Compression

VOIP is being implemented on the Company network. In a properly designed network, what
is the maximum amount of time a voice package should spend crossing a network?

VOIP is being implemented in the Company network and you need to assess the need for
QoS. Which of the following network problems would indicate a need to implement QoS
features? (Select three)

The Company network is displayed in the following topology exhibit:

Workstation 1 traffic is set for cos 5 and the switch CompanyA sends workstation 1 traffic to
the switch CompanyB. However, not all of the traffic from Switch CompanyA is from
workstation 1.
Switch CompanyA configurations Switch CompanyB Configuration:
mls qos mls qos
interface fa0/1 interface fa0/1
switchport mode trunk switchport trunk mode
switchport trunk encapsulation dot 1q switchport trunk encapsulation dot 1q
switchport trunk native vlan 1 switchport trunk native vlan 1
Frames from Workstation 1 are given the rightful priority through Switch CompanyA, but
Switch CompanyB doesn’t reciprocate, and treats Workstation 1 frames as if they have no
precedence. Which of the following actions will prioritize traffic from Workstation 1?

Refer to the exhibit. A trunk link is connected between switch A_SW and switch D_SW.
Based on the configuration shown in the exhibit, how would the traffic coming from the
switch A_SW be managed?

Refer to the exhibit. Which switch interface configuration command would automatically
configure quality of service (QoS) for voice over IP (VoIP) within a QoS domain?

Refer to the exhibit. What is the effect on the trust boundary of configuring the command mls
qos trust cos on the switch port that is connected to the IP phone?
