where are the two optimal locations for trust boundaries to be configured by the network administrator？（）
A.host
B.IP phone

Wireless has been operating correctly in the campus infrastructure. After the wireless controllers are upgraded from LWAPP to CAPWAP， access points no longer boot and operate normally.
What is the most likely issue causing this problem？（）
A.VLAN assignments
B.DHCP option 43
C.PoE
D.ACL
E.QoS
A standalone wireless AP solution is being installed into the campus infrastructure. The access points appear to boot correctly， however， wireless clients are not obtaining correct access. You verify that the local switch configuration connected to the access point appears as the following：
interface ethernet 0/1
switchport access vlan 10
switchport mode access
spanning-tree portfast
mls qos trust dscp
What is the most likely issue causing the problem？（）
A.QoS trust should not be configured on a port attached to a standalone AP.
B.QoS trust for switchport mode access should be defined as "cos".
C.switchport mode should be defined as "trunk" with respective QoS.
D.switchport access vlan should be defined as "1".
A campus infrastructure supports wireless clients via Cisco Aironet AG Series 1230， 1240， and 1250 access points. With DNS and DHCP configured， the 1230 and 1240 access points appear to boot and operate normally； however， the 1250 access points do not seem to operate correctly.
What is the most likely issue causing this problem？（）
A.PoE
B.DHCP with option 150
C.DHCP with option 43
D.DNS
E.switch port does not support gigabit speeds
You work as a network engineer for . You study the exhibit carefully.
What happens when the switch 2 is connected to the rest of the network in the VTP domain Lab_Network？（）
Exhibit：
A.The recently introduced switch 2 removes all configured VLANs throughout the VTP domain.
B.The recently introduced switch 2 creates a STP loop in the VTP domain.
C.The recently introduced switch 2 switches over to VTP transparent mode in order to be included into the VTP domain.
D.A trunk should be configured between the two switches in order to integrate 2 into the VTP domain.
E.The recently introduced switch 2 adds one more VLAN to the VLAN database in the VTP domain.
