A hospital needs an upgrade to 802.11ac for its wireless network. The wireless network supports: wireless medical devices medical staff voice communicators laptops in nurse stations medical staff tablets visitor and patient personal devices All of these devices support both the 2.4GHz and 5GHz band. Assuming about a max throughput of 150 Mbps per AP, the hospital would like to support about 4 Mbps per client. The architect has used VisualRF to plan the AP placement on one of the floors, which the hospital expects will need to support about 800 wireless devices. The exhibits show heatmaps from this plan. The architect also plans to deploy APs in stairwells between floors. How well does the plan meet the requirements?

A) The current AP placement fails to account for the lead-lined walls that are common in patient and exam rooms.
B) The current AP placement fails to provide adequate signal for the voice communicators in several areas.
C) The current AP placement meets coverage requirements, but does not meet capacity requirements.
D) The current AP placement meets the customer requirements in terms of coverage and capacity.

E) None of the above
F) A) and C)

Refer to the exhibit. An architect has planned the wireless and wired access layers for a network upgrade. The entire solution must support 9,000 wireless devices and 2,250 wired endpoints. The campus core must meet these requirements: no more than 4:1 oversubscription on the links to the data center switch-level redundancy near instant failover if one core switch fails link aggregations between access layer and core same switch software used across the entire campus Which exhibit shows a campus core that meets the customer needs?

A stadium wants to deploy location-based services, including blue-dot wayfinding over a 200,000 square foot (18,580 sq. m) area. The customer also wants to enable targeted notifications when guests walk past particular areas. The customer has selected a 1 year subscription. The exhibit shows the BOM that the architect created in Iris. Which correction should the architect make?

In which scenario do Aruba 2930M Series switches, but not Aruba 2930F Series switches, meet the needs for an upgrade of the wired access layer?

In which of these scenarios do the customer requirements point towards tunneled node, or dynamic segmentation, on AOS-Switches?

Refer to the exhibit. An architect needs to design the topology for a new wired network at a campus with three buildings. The exhibit above shows the cabling layout. The customer requires link redundancy at all layers, up to one switch-to-switch link can fail without an effect on client connectivity. The architect has determined that the closet of each floor should have three Aruba 2930M switches, and the core will use Aruba 5406 switches. The aggregation layer, if used, will use Aruba 3810M switches. However, the customer prefers the elimination of the aggregation layer and has asked the architect to advise the impact of the elimination of this layer. Where would the elimination of the aggregation layer require rewriting?

A customer has critical wired endpoints and wants to minimize the chances they will lose their connection to the network. These endpoints are dual-homed, each with two Ethernet connections that are in a link aggregation. The architect plans to deploy two 5406R switches in the closet. What else should the architect specify in the plan?

A customer has phones used as wireless Voice over IP (VoIP) devices. Which is one implication for the design?

A network architect plans to propose a virtual Mobility Master (VMM) for a new solution. The solution will support up to 4,800 wireless client devices and include: two Virtual Mobility Controllers (VMCs) in a cluster 180 APs Which licenses should the architect propose?

Refer to the exhibit. The customer requires a solution for the writing closet shown in the exhibit. The closet serves the entire floor, which is wired for CAT5e cable. The closet has four CAT5e cables to the data center 110 feet (34 m) away. The switch or switches in this closet will need to support 100 wired endpoints and 16 AP-345s. The switch or switches must connect to the network core, Aruba 5406R switches, in the data center on uplinks that provide at least 20 Gbps bandwidth total. What is one benefit of an Aruba solution for meeting these requirements?

Refer to the exhibit. 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.)

Refer to the exhibit. A customer needs a wireless network upgrade and has these requirements: Support any applications used on a wired connection Support up to 2500 wireless clients Support seamless roaming from floor to floor and building to building Continue to function seamlessly if one AP or controller fails The architect has designed the local infrastructure for the network as shown in the exhibit. Which change should the architect make to better meet customer requirements and best practices?

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. What is a correct plan for firewall rules for the guest role? (The options describe the rules, but do not need to use correct command syntax.)

The airport needs to support several different SSIDs, including: four for individual airlines one for the airport as a whole one for airport security The airport security traffic must terminate on different mobility controllers (MCs) from the rest of the airport traffic and be managed entirely separately. Airlines also want to terminate traffic at their MCs. The airport MCs and airport security MCs require redundancy while airlines do not. Which plan for MCs and Mobility Master (MM) meets the needs of this scenario?

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?
