NO.1 One of your customers plans on providing wireless coverage to a warehouse facility. After performing an
initial walkthrough, you collect the following information:
-The central part of the warehouse is between 400 and 600 feet (122 to 183 meters) from the warehouse
switches mounted on the walls.
-The warehouse map was provided by the customer and is displayed in the exhibit.
-The warehouse storage is composed of metallic racks with varying inventory levels and contents, from
electronics and plastic toys to food pallets and juice bottles.
-Workers need basic data coverage from their working location, and are not highly mobile. They usually
work from one single aisle, and their laptop is on a cart with wheels.
What would be your recommendation to provide coverage to the central area (indicated by a blue circle)
of the warehouse?
A. Equip workers laptops with a directional antenna and install APs less than 328 feet (100m) away from
the switch.
B. In this case, extend the cable length just beyond 328 feet (100 m) and position APs as close as
possible to the central area of the warehouse.
C. Position APs along the walls, and equip the APs with Yagi antennas to cover the central area.
D. Install APs for client access in the central area and use a mesh backhaul link to connect to the DS.

NO.2 In a centralized WLAN architecture, what new problem may arise when you change the data forwarding
model from centralized to distributed? (Choose 2)
A. APs that were designed for a centralized forwarding model may not support all features in distributed
forwarding mode.
B. The Ethernet switch ports to which APs are connected may need to be reconfigured to support VLAN
tagging and QoS at the network edge.
C. All RRM controls will also need to be distributed to a master AP that acts as a channel and transmit
power arbiter for other APs in the ESS.
D. Centralized control functions, such as key management and distribution, RRM, and load balancing will
no longer be supported.
E. APs will not have the processing capabilities to support AES-CCMP, so TKIP will be the recommended
encryption method.

NO.3 Which definition correctly describes the local MAC
variation of the centralized WLAN architecture?
A. All MAC functions are performed by the AP. A minimal subset of network control is offloaded to the
WLAN controller along with management and monitoring functions.
B. PHY functions are performed directly by the AP. MAC functions are divided almost equally between the
WLAN controller and the AP, according to the time sensitivity of the feature or service.
C. The AP provides the RF termination point for the WLAN, but performs very few of the WLAN functions
or services. The WLAN controller performs all MAC functions and the AP is very simple and lightweight.
D. All RF-, data-, and control-related WLAN functions are performed by the AP. APs coordinate network
services with one another and are managed by a WNMS, so no WLAN controller is used in this
architecture.

NO.5 Given: You are the network administrator for ABC Company. Your manager has recently attended a
wireless security seminar. The seminar speaker taught that a wireless network could be hidden from
potential intruders if you disabled the broadcasting of the SSID in Beacons and configured the access
points not to respond to Probe Request frames that have a null SSID field.
Your manager suggests implementing these security practices. What response should you give to this
suggestion? (Choose two)
A. Any 802.11 protocol analyzer can see the SSID in clear text in frames other than Beacons and Probe
Response frames. This negates any security benefit of trying to hide the SSID in Beacons and Probe
Response frames.
B. This security practice prevents manufacturers' client utilities from detecting the SSID. As a result, the
SSID cannot be obtained by attackers, except through social engineering, guessing, or use of a WIPS.
C. Although it does not benefit the security posture, hiding the SSID in Beacons and Probe Response
frames can be helpful for preventing some users (such as guests) from attempting to connect to the
corporate network.
D. Any tenants in the same building using advanced penetration testing tools will be able to obtain the
SSID by exploiting WPA EAPOL-Key exchanges. This poses an additional risk of exposing the WPA key.
E. To improve security by hiding the SSID, the AP and client stations must both be configured to remove
the SSID from association request and response frames. Most WLAN products support this.

NO.20 ABC Company has a 2.4 and 5 GHz WLAN deployment supporting four bands in the 5 GHz range
(UNII 1, UNII 2, UNII 2e, and UNII 3). DFS functionality is enabled as required by the regulatory domain.
Band steering is also enabled to encourage dual-band clients to use frequency bands with more capacity.
Your performance analysis shows that many dual-band VoWiFi client devices will move back and forth
between 2.4 and 5 GHz as the user roams throughout the building. All APs have 2.4 and 5 GHz radios
enabled.
This "band hopping" behavior is viewed by network staff to be undesirable. What is the most likely cause
of the unpredictable client band selection behavior?
A. Interference from 5 GHz radar sources has increased frame corruption and retries on channels 36-48
in UNII 1.
B. 5 GHz frequencies offer better RF penetration than 2.4 GHz, but 2.4 GHz offers more voice call
capacity and lower latency than 5 GHz.
C. The voice client does not support DFS, and therefore experiences some 5 GHz coverage holes as it
moves through the network.
D. The client's band selection algorithm prefers 5 GHz, but band steering behavior usually steers 75-85%
of client devices to 2.4 GHz.

NO.5 In a centralized WLAN architecture, what new problem may arise when you change the data forwarding
model from centralized to distributed? (Choose 2)
A. APs that were designed for a centralized forwarding model may not support all features in distributed
forwarding mode.
B. The Ethernet switch ports to which APs are connected may need to be reconfigured to support VLAN
tagging and QoS at the network edge.
C. All RRM controls will also need to be distributed to a master AP that acts as a channel and transmit
power arbiter for other APs in the ESS.
D. Centralized control functions, such as key management and distribution, RRM, and load balancing will
no longer be supported.
E. APs will not have the processing capabilities to support AES-CCMP, so TKIP will be the recommended

NO.8 One of your customers plans on providing wireless coverage to a warehouse facility. After performing an
initial walkthrough, you collect the following information:
-The central part of the warehouse is between 400 and 600 feet (122 to 183 meters) from the warehouse
switches mounted on the walls.
-The warehouse map was provided by the customer and is displayed in the exhibit.
-The warehouse storage is composed of metallic racks with varying inventory levels and contents, from
electronics and plastic toys to food pallets and juice bottles.
-Workers need basic data coverage from their working location, and are not highly mobile. They usually
work from one single aisle, and their laptop is on a cart with wheels.
What would be your recommendation to provide coverage to the central area (indicated by a blue circle)
of the warehouse?
A. Equip workers laptops with a directional antenna and install APs less than 328 feet (100m) away from
the switch.
B. In this case, extend the cable length just beyond 328 feet (100 m) and position APs as close as
possible to the central area of the warehouse.
C. Position APs along the walls, and equip the APs with Yagi antennas to cover the central area.
D. Install APs for client access in the central area and use a mesh backhaul link to connect to the DS.

NO.9 Which definition correctly describes the local MAC
variation of the centralized WLAN architecture?
A. All MAC functions are performed by the AP. A minimal subset of network control is offloaded to the
WLAN controller along with management and monitoring functions.
B. PHY functions are performed directly by the AP. MAC functions are divided almost equally between the
WLAN controller and the AP, according to the time sensitivity of the feature or service.
C. The AP provides the RF termination point for the WLAN, but performs very few of the WLAN functions
or services. The WLAN controller performs all MAC functions and the AP is very simple and lightweight.
D. All RF-, data-, and control-related WLAN functions are performed by the AP. APs coordinate network
services with one another and are managed by a WNMS, so no WLAN controller is used in this
architecture.
