A customer has multiple medium and large branch sites, each of which requires between 8 and 16 APs and supports between 200 and 600 wireless clients. Every branch site has an internet connection, which it uses to reach the central data center. The customer would prefer the WAN links to be optimized in the solution. Each side handles between 1 and 2 Gbps of traffic, most of which goes to the central data center. The data center has 7210 controllers for terminating the VPN connections.
Which branch office solution best meets the customer needs?
A. CAPs and branch office controllers with an SD-WAN license
B. IAPs and no branch office controllers
C. CAPs and branch office controllers
D. RAPs and no branch office controllers

A company needs a new wireless solution for its large campus with multiple buildings. The campus has 8,000 users, and the company also has 1000 users who use VIA concurrently. The customer requires full redundancy for the Mobility Controllers (MC), including seamless roaming and stateful failover for the main site. Buildings are close enough together for users to roam between them. The exhibit shows the existing wired network. The architect plans to propose: 500 APs (100 each in Building 1 and 2, 200 each in Buildings 3 and 4). two 7030 MCs two 7220 MCs one MM appliance
The exhibit shows the existing wired network at the main site.
Where should the architect plan to connect the MCs? (Potential locations are numbered in the exhibit.)
A. two 7030 MCs at 6; two 7220 MCs at 5
B. one 7030 MC at 1 and one at 2; one 7220MC at 3 and one at 4
C. two 7030 MCs at 5; one 7220 MC at 3 and one at 4
D. all of the MCs at 6

A museum wants to add full 802.11ac wireless coverage across the building, which is about 210 feet (64 m) by 330 feet (100m). The museum has 15-foot (4,6 m) ceilings and stone interior walls. The network needs to support up to 600 wireless guest devices. The exhibit also shows a preliminary plan for AP locations. The museum has eight Ethernet drops in the lobby and gift shop, but has otherwise not been wired.
What is one recommendation that the architect should make to ensure a successful deployment?
A. use of directional antennas to avoid lost signal
B. addition of a writing closet closer to the north side
C. use of at least CAT5 cable to connect to the APs
D. addition of about 10 APs to achieve adequate density
A customer has multiple, very small branch sites that require just one or two APs each. The office has a
local Internet connection, but the traffic is destined to the corporate data center, which has an Aruba
wireless solution.
Which branch office solution best meets the customer needs?
A. RAPs and 7005 branch office controllers with an SD-WAN license
B. RAPs and no branch office controllers
C. CAPs and 7005 branch office controllers
D. IAPs and 7005 branch office controllers with an SD-WAN license
A school district has instant APs (IAPs) at multiple locations. The school district wants a simpler way to manage the IAPs from a single location. However, it does not have the IT staff to handle the installation
and management of a management solution on site. What should the architect recommend?
A. Purchase a subscription for Aruba Central device management.
B. Deploy Aruba AirWave in central location.
C. Purchase licenses for a Virtual Mobility Controller (VMC).
D. Deploy an Aruba MC in a central location, and convert IAPs to CAPs.
What is one reason that an architect might choose to use pico-cell coverage rather than overhead in a stadium?
A. to avoid major rewiring and construction concerns
B. to save money by using less powerful and less expensive APs in the deployment
C. to support a higher device density with a higher level of channel reuse
D. to maximize coverage per-AP through the use of calculated directional antennas
A retailer wants to provide wireless services for guests across a section of store floor, which consists of 82 foot (25m) long aisles of cans and dry food goods. The shelves are six feet (1.8 m) high, and the ceiling height is 13 feet (4 m) high. The architect recommends overhead APs deployed at 40-50 foot (12 to 15 m) intervals every few aisles rather than in every aisle.
What is one factor that justifies this recommendation?
A. the low transmit power of most guest devices
B. the low shelf height relative to ceiling height
C. the aisle length
D. the low ceiling height
Case study
A retailer needs a wireless and wired network upgrade, as well as an authentication and access control solution for a network that includes a main office with a three-floor building and six branch sites. The branch users all use resources at the main corporate office. Branch office employees will use wireless connections. At the main office, employees use wired and wireless connections. The customer wants the strongest authentication for employee wireless connections. It is also important that the MC role-based firewall can implement consistent access controls on employee connections no matter where the employees connect and no matter how they connect (wirelessly or, at the main site, wired). The customer also needs to provide complimentary wireless access for guests. Guest should be redirected to a portal, through which they can register and login. The customer would like two SSIDs, CompanyXEmployee and CompanyXGuest. The company wants to divide employees in two groups, managers and staff. In the corporate network, managers should only have access to Server Group Managers and staff should only have access to Server Group Staff. Each server group includes necessary services such as domain and DHCP, as well as servers that the employees access to do their jobs. All employees should also have access to the Internet. Guests should only have HTTP and HTTPS access, and only to the Internet.
The customer has: a maximum of 1000 employee devices a maximum of 100 guest devices at the same time 500 devices on wired ports at the main site, which will be supported by 12 new AOS-Switches (mostly employee laptops, as well as a few non-802.1X capable printers, which should just communicate with print servers)
The devices used by employees include 450 company-issued laptops, which the company wants to screen for security issues and violations of security policies. All authentications are assumed to be concurrent.
To fulfill the requirements for the wireless network upgrade, the architect plans to propose: 5 RAPs at each of 6 branch sites 60 APs at the main site
The architect will also propose an MM and ClearPass. The architect still needs to plan the Mobility Controllers (MCs). The customer requires high availability for wireless services and redundancy for the MCs. If a single MC fails, the network must continue to function without impact. If an MC fails, the customer must also receive a replacement component for the failed component by the next business day so that their IT staff can install it and get the network back to normal operation as soon as possible. Software upgrades must also be seamless, without the introduction of any downtime for wireless services, and the customer needs to be able to obtain the latest software over the lifetime of the solution for the next several years.
Which plan for the VLANs assigned to users at the main site follows the best practices? (Note that the infrastructure could have additional VLANs in various locations; this plan refers only to user VLANs.)
A. VLAN 10 for wired and wireless manager devices; VLAN 11 for wired and wireless staff devices; VLAN 12 for all wireless guest devices
B. VLAN 10-12 for wireless employee devices on Floors 1-3 (divided by floor); VLANs 13-15 for wireless guest devices on Floors 1-3; VLANs 16-18 for wired employee devices on Floors 1-3
C. VLAN 10 for all wireless devices; VLANs 12-14 for wired employee devices on Floors 1-3 (divided by floor)
D. VLAN 10 for wireless employee devices; VLAN 11 for wireless guest devices; VLANs 12-14 for wired employee devices on Floors 1-3 (divided by floor)
A writing closet needs to support 20 APs and 110 wired endpoints. It has four strands of OM3 fiber to the network core 150 feet (45 m) away. The customer wants the links to the network core to support at least 10GbE. The customer also requires no loss in connectivity for the switches in the closet, even with the loss of one link. The architect plans to recommend three 2930M 40G 8SR PoE+ switches, two 4-port SFP+ modules, and two SFP+ SR transceivers.
What should the architect change about the plan?
A. Add three 10GbE direct attach cables (DACs) or three stacking cables.
B. Add a stacking module for each switch and three stacking cables.
C. Change the two SFP+ SR transceivers to SFP+ LRM transceivers.
D. Add one 4-port SFP+ module and one SFP+ SR transceiver.
Refer to the exhibit.
