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

In this WLAN segment， what are three requirements for configuring these Aironet access points（APs） that will allow for all wireless clients to work without service interruption while roaming fromaccess point to access point？（）
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....only with the native VLAN
F....with the native VLAN
A.association request/response， probe request/response， authentication request/response
B.association request/response， authentication request/response， probe request/response
C.probe request/response， authentication request/response， association request/response
D.probe request/response， association request/response， authentication request/response
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
Exhibit：
You work as a network technician. Please study the exhibit carefully. In this wireless network， theLAP （lightweight access point） attempts to register to a WLC （Wireless LAN Controller）. What kindof message is transmitted？（）
A.The lightweight access point will send Layer 2 and Layer 3 Lightweight Access Point （LWAPP）mode discovery request messages at the same time
B.The lightweight access point will send Layer 3 Lightweight Access Point （LWAPP） modediscovery request messages only
C.The lightweight access point will send Layer 2 Lightweight Access Point （LWAPP） mode discovery request messages. If the attempt fails， the LAP will try Layer 3 LWAPP WLC discovery
D.The lightweight access point will send Layer 2 Lightweight Access Point （LWAPP） modediscovery request messages only
