Refer to the exhibit. What is the effect when the switchport priority extend cos 3 command isconfigured on the switch port interface connected to the IP phone？（）
A.Effectively， the trust boundary has been moved to the PC attached to the IP phone
B.The computer is now establishing theCoS value and has effectively become the trust boundary
C.The IP phone is enabled to override with aCoS value of 3 the existing CoS marking of the PCattached to the IP phone
D.The switch will no longer tag incoming voice packets and will extend the trust boundary to thedistribution layer switch
E.RTP will be used to negotiate aCoS value based upon bandwidth utilization on the link

Look at the graphic below， the connectivity between Cisco IP phone access port and theworkstation CK-PC has been established， how to manage the traffic？（）
A.The IP phone access port will override the priority of the frames received from the CK-PC
B.The IP phone access port would trust the priority of the frames received from the CK-PC
C.The switch port FaO/4 would neglect the priority of the frames received from the CK-PC
D.The switch port FaO/4 would trust the priority for the frames received from the CK-PC
An IP phone connects a user to a switch as shown below：
Based on the diagram shown above， which statement is true about the voice traffic coming to theswitch access port that is connected to the IP phone？（）
A.A PC connected to a switch port via an IP phone is unaware of the presence of the phone
B.The traffic on the voice VLAN must be tagged with 802.1p encapsulation in order to coexist onthe same LAN segment with a PC
C.To improve the quality of the voice traffic， no other devices should be attached to the IP phone
D.The voice VLAN must be configured as a native VLAN on the switch
E.A PC connected to a switch port via an IP phone must support a trunking encapsulation
A.Antenna power is a relative value reference to dBi
B.LWAPP allows encrypted communications between lightweight access points and WLANcontrollers.
C.Characteristics of antennas are directionality， gain， and polarization
D.Power over Ethernet （PoE） is only available when a WLAN controller is integrated into thenetwork
E.The WLAN solution Engine （WLSE） is used to control lightweight access points
F.One of the advantages of the lightweight WLAN solution is that the devices act indepently

All access points should be configured....
A....with a unique IP subnet range
B....with identical SSIDs
C....within the same IP subnet
D....with the same guest mode SSID

E.None of the other alternatives apply
Exhibit：
In this scenario the signal transmitted from the AP is reflected off a wall， resulting in multipathinterference at the client end （ClientA）. Which of the following statements is true？（）
A.The transmitted signal from the AP arrives at the client at slightly different times resulting inphase shifting
B.Multipath interference can be solved by using dual antennas
C.If signal 2 is close to 360 degrees out of phase with signal 1， the result is essentially zero signalor a dead spot in the WLAN
D.Multipath interference is less of an issue when using a DSSS technology because multipath isfrequency selective
E.If signal 1 is in phase with signal 2， the result is essentially zero signal or a dead spot in theWLAN
F.None of the other alternatives apply
