As XYZ Company selects a product to deploy, what two IEEE amendments, which are included in
802.11- 2016, should be supported to provide the management frame protection and fast secure roaming security features?
A. 802.11r and 802.11w
B. 802.11j and 802.11k
C. 802.11r and 802.11k
D. 802.11z and 802.11w
正解：A

質問 2：

B. RBAC
C. SNMP
D. WPA2
正解：B

質問 3：
What security method is commonly used for VoIP handsets when the infrastructure does not support OKC or FT roaming?
A. WPA2-Enterprise with EAP-TLS
B. WPA2 -Personal
C. WPA2-Enterprise with EAP-TTLS
D. WPA2-Enterprise with PEAP
正解：A

質問 4：
Return Loss is the decrease of forward energy in a system when some of the power is being reflected back toward the transmitter.
What will cause high return loss in an RF transmission system, including the radio, cables, connectors and antenna?
A. The use of cables longer than one meter in the RF system
B. High output power at the transmitter and use of a low-gain antenna
C. A Voltage Standing Wave Ratio (VSWR) of 1:1
D. An impedance mismatch between components in the RF system
正解：D

質問 5：
What statement about 802.11 WLAN performance is true?
A. In most WLANs, no special skill or tuning is required to get peak performance
B. In modern networks, both centralized and distributed data forwarding work well for most standard office deployments
C. WLANs perform better as more wireless clients connect with each AP
D. To get the best performance out of an AP, you should disable data rates of 72 Mbps and lower
正解：D

質問 6：
You administer a small WLAN with nine access point. As a small business, you do not rum a RADIUS server and use WPA2-Personal for security.

A. FCS errors in frames transmitted to and from the AP.
B. Throughput speed in Mbps.
C. Signal strength of access point beacons received
D. PING latency when testing against an internet server
正解：C
