- B . 1 Gbps
- C . 5 Gbps
- D . 10 Gbps
A customer has some employees that travel to various locations, where these employees will need Wi-Fi access at these locations. Because many of these locations do not have wireless support, the employees will need to carry an AP solution with them. Internet connectivity, if it doesn’t exist at these locations, will be provided by a national phone company USB wireless card which will be connected to AP. The wireless solution needs minimal bandwidth, but needs to minimally support 802.1 lac wave 1 devices.
Which Aruba AP wireless solution would meet the needs of these employees most effectively and cost efficiently?
- A . 318
- B . 303H
- C . 365
- D . 203R
NewStellar has a main corporate campus in a business park with two adjacent buildings. Each building has three floors and each floor is 322 x 175 feet (98 x 53 meters) for 56,350 square feet (5,235 square meters) total. The ceiling for each floor is 12 feet (3.6 meters) high with a drop-down ceiling at 10 feet (3 meters).
The network architect has given you one floor to analyze, Building 1 Floor 2, shown in the attached exhibit.
This floor has a central main corridor with washrooms, stairs, elevators and supply and network cabinets. There are cubicles around the perimeter of the floor. The central part main corridor’s dimensions contain 9,350 square feet (870 square meters).
Assuming that wireless coverage is not required in the central area, which square footage (square meter) value should a network architect use when determining the number of APs in a capacity design for each floor?
- A . 55.750 square feet {5,175 square meters)
- B . 56.350 square feet {5,235 square meters)
- C . 47.000 square feet {4,365 square meters)
- D . 338,100 feet {31,410 square meters)
A network architect is redesigning a wireless network. The architect begins by analyzing the number of spatial streams supported by APs of various vendors as well as the wireless devices currently in the network, if the company wants to ensure that new wireless design, including user wireless devices, support Multi-User MIMO (MU-MIMO).
Which standard or standards must the wireless products support?
- A . Only 802.11ax and 8011.ac
- B . Only 802.11ax
- C . Only 802.11ax,802.1lac, and 802.l1n
- D . Only 802.11ax,802.11ac, 802.11n, and 802.11a
A network architect is given the task to design a new network solution for NewStellar Company, Inc. NewSteiiar has a main corporate campus in a business park with two adjacent buildings.
The network architect has given one floor to analyze, Building 1 Floor 2, shown in the attached exhibit.
Each building has three floors and each floor is 322 x 175 feet (98 x 53 meters) for 56,350 square feet (5,235 square meters) total, which results in a total of 338,100 feet (31,410 square meters) for the entire building space. Each floor has a central main corridor with washrooms, stairs, elevators and supply and network cabinets. There are cubicles around the perimeter of the floor. The central part main corridor’s dimensions contain 9,350 square feet {870 square meters).
Because of security concerns, video cameras will be installed throughout the facility. There are 16 of these per floor, 8 per wiring closet. The cameras are non-WiFi capable and require POE 802.3af-capable switch ports from which to draw power.
A wireless capacity design is required. Assuming that wireless coverage is required across the Building 1, Floor 2, including the central area, and that half the required APs will connect to each wiring closet, approximately how many POE+ ports will be required per wiring closet for all devices that have POE or POE+ needs?
- A . 30
- B . 22
- C . 42
- D . 8
