A. Low power APs
B. Low gain antennas
C. Personal Protective Equipment (PPE)
D. Indoor APs
正解：C
質問 2：
What is the most cost-effective way to accurately measure the height of a ceiling when ladder use is not allowed?
A. Use a laser measure to measure the distance from the floor to the ceiling
B. Estimate the height based on known object sizes
C. Rent a lift-cart to lift you up to the ceiling
D. Gather measurements from other objects and do the math
正解：A
質問 3：
What are some common problems with short (12 or fewer characters) ASCII passphrases in WPA/WPA2- Personal networks?
Response:
A. They lead to weak group keys in a BSS.
B. They are more susceptible to dictionary attacks than longer passphrases.
C. They only produce a 64-bit PMK instead of a 256-bit PMK.
D. Very few AP and client vendors support entry of an ASCII-based passphrase.
正解：B
質問 4：
A bandpass filter has a maximum in-band loss of 1.5 dB, ripple of 0.4 dB, and a return loss of 15 dB. What is the minimum in-band loss?
Response:
A. 1.9 dB
B. 1.1 dB
C. 13.5 dB
D. 1.5 dB
正解：B
質問 5：
ABC Company has a WLAN controller with 10 controller-based APs; the Voice SSID is configured for centralized data forwarding. Each AP is connected to an access port on a layer-2 Ethernet switch. Each layer-2 switch is uplinked to a single layer-3 core Ethernet switch. The WLAN controller is connected directly to the layer-3 core Ethernet switch. Layer-3 tunnels are created between all controller-based APs and the WLAN controller. A voice server is connected to the layer-3 Ethernet switch.
When a voice-enabled QoS STA sends an IP data packet to a voice server in this scenario, the DSCP value carried in the STA's IP data packet gets mapped to what and by which device?
A. The DSCP value is mapped to an IEEE 802.1Q priority tag value by the WLAN controller.
B. The DSCP value is mapped to an IEEE 802.1p (802.1D-2004) UP value by the access point.
C. The DSCP value is mapped to the DSCP value in the encapsulating IP header by the layer-3 switch.
D. The DSCP value is mapped to an IEEE 802.1Q VLAN tag by the access point.
正解：A
質問 6：
An organization is implementing a new WLAN. They are upgrading a very old 802.11g network that only a few devices used Now. they expect more than 250 devices to use the new WLAN that will operate 802.11ax Aps. What wired-side consideration should you address in your design recommendations?
A. Spanning-tree loops
B. DHCP pools
C. Modem pools
D. Client ARP tables
