質問 1：
In this question, you will compare the mobility processes of a network that supports WPA2Personal and WPA2-Enterprise. Assume the use of a 15-character ASCII passphrase for WPA2-Personal and EAP-TTLS/MSCHAPv2 with WPA2-Enterprise. Also, assume that proprietary roaming protocols are not supported.
When a device transitions from one BSS to another within the same ESS, what steps must be performed in the WPA2-Enterprise transition that are not performed in the WPA2Personal transition? (Choose 2)
A. Open System Authentication
B. Conversion of passphrase to PMK
C. 4-Way Handshake
D. 802.11 Reassociation
E. 802.1X authentication
F. Transfer of PMK from AAA server to authenticator
正解：E,F

質問 2：
You are tasked with designing the WLAN to accommodate certain high density areas on your university campus where users are highly transient (frequently come and go). With a limited DHCP pool size (subnet mask = 255.255.252.0) for this WLAN subnet, you want to ensure that your DHCP addresses are used efficiently and are not exhausted, which would prevent new client associations. The DHCP server is a Windows Server 2008 machine. Your design task is to determine the best configuration to allow as many users as possible while avoiding WLAN service interruptions and also to use the available addresses as efficiently as possible.
What setting would be most effective at achieving this design task?
A. Enable mandatory admission control
B. Set the 802.1X re-authentication timer to 10 minutes
C. Set the AES rekey interval to 5 minutes
D. Set the DHCP lease for this pool to 20 minutes
E. Set the inactive wireless client timeout (client age-out) to 5 minutes
F. Enable WLAN Controller DHCP relay
G. Set the RTS threshold to 2346 bytes
H. Set the maximum client limit per radio to 64
正解：D

質問 3：
Given: Assume that music on hold (MOH) features are unicast only.
What VoWiFi implementations require multicast packet delivery support by the WLAN infrastructure?
A. Flat (non-VLAN) VoWiFi implementations
B. FMC phones
C. VoWiFi soft phones
D. All VoWiFi implementations
E. Push-to-Talk VoWiFi phones
正解：E

質問 4：
An associated STA detects a new BSS with the same SSID as the STA's current BSS. The new BSS uses a different IP subnet than the current BSS. If the STA is configured to use 802.1X/EAP preauthentication, what is likely to occur?
A. The STA will attempt to preauthenticate and succeed if IP Mobility is enabled on the AP or WLAN controller.
B. The STA will attempt to preauthenticate, but fail because the new BSS uses a different data-link broadcast domain.
C. The STA will attempt to preauthenticate and succeed if the current AP has shared its cached PMK.
D. The STA will not attempt to preauthenticate because the new BSS uses a different IP subnet.
E. The STA will attempt to preauthenticate and succeed if DHCP is supported on the new subnet.
正解：B

質問 5：
After surveying for the ideal mounting locations for APs, you have been asked to compromise RF propagation optimization due to aesthetic concerns raised by your customer. In the end, you've decided to mount the APs in the ideal locations and paint the APs so they go unnoticed in the environment.
What is a valid recommendation or consideration when painting APs? (Choose 2)
A. Most AP models for indoor environments come in a variety of form factors and colors. Painting is never recommended.
B. Do not paint the notification LEDs on the AP, but configure them to be dim or turned off altogether until troubleshooting is required.
C. Painting APs may void the product manufacturer's warranty.
D. Always use paints with metallic dye in them to prevent potential RF propagation impact.
E. Painting APs always introduces a fire and gas emissions hazard and should be avoided for all indoor APs.
正解：B,C

質問 6：
Excessive uplink RTP frame retransmissions can result in ____________. (Choose 3)
A. MOS scores in excess of 5
B. Shortened battery life of a transmitting station
C. Head-of-Line blocking at the receiver
D. Deauthentication of the transmitter by the receiver
E. Increased jitter in a VoWiFi connection
F. Lowering of the data transmission rate by the transmitting station
正解：B,E,F
