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

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
A.Switchover ensures that Layer 2 through Layer 4 traffic is not interrupted
B.Redundancy requires BGP， OSPF， EIGRP， or IS-IS
C.Redundancy provides fast supervisor switchover for all Cisco Catalyst 6500 series switches
D.Switchover can be caused by clock synchronization failure between supervisors
A.independent of SSO
B.NSF combined with SSO enables supervisor engine load balancing
C.supported by RIPv2， OSPF， IS-IS， and EIGRP
D.supports IPv4 and IPv6 multicast
E.prevents route flapping
F.dependent on FIB tables
