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

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.
Exhibit：

E.The show auto qos command shows the user-defined QoS settings.
F.The show auto qos command does not display user configuration changes currently in effect.
A.DAI intercept all ARP packets on untrusted ports
B.DAI determines the validity of an ARP packet based on the valid MAC address-to-IP address bindings stored in the DHCP Snooping database.
C.DAI is used to prevent against a DHCP Snooping attack.
D.DAI forwards all ARP packets received on a trusted interface without any checks.
E.DAI forwards all ARP packets on untrusted ports.
F.DAI determines the validity of an ARP packet based on the valid MAC address-to-IP address bindings stored in the CAM table.
A.Classifying and marking traffic should be done as close to the traffic source as possible.
B.Classifying and marking traffic should be done at the distribution layer.
C.Traffic is classified and marked as it travels through the network.
D.If untrusted traffic enters a switch， it can be marked with a new QoS value appropriate for the policy in place.
E.The trust boundary moves depending on the type of traffic entering the network.
