Question1:


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?

Question2: Refer to the exhibit.

A customer needs a network upgrade. The customer has these availability requirements for wireless access:
One MC and one core switch can fail with immediate, stateful failover for client connections.

Network upgrades can occur without the requirement of a maintenance window.

The exhibit shows the architecture plan.
Which technologies should the architect recommend?

Question3: 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.)

Question4: Refer to the exhibit.

A casino and a retail space has an existing Aruba network with Aruba AP-335s. The customer wants to deploy Meridian and enable proximity-based campaigns. The exhibit shows a segment of the floor plan.
When visitors enter the areas circled in the exhibit, they should receive a targeted notification about promotions and sales.
What should the architect explain to the customer about how to finish the solution?

Question5: 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?

Question6: A customer has phones used as wireless Voice over IP (VoIP) devices.
Which is one implication for the design?

Question7: 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?

Question8: What is one reason that an architect might choose to use pico-cell coverage rather than overhead in a stadium?

Question9: 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.)

Question10: Refer to the exhibit.

A customer has these availability requirements:
loss of one controller with stateful failover and without impact on wireless client connectivity

loss of one core switch without loss of connectivity for any endpoints or APs in the building

loss of any one switch-to-switch or MC-to-switch link without loss of connectivity for any endpoints or

APs in the building and with minimal impact on infrastructure functionality loss of any one access switch with minimal impact to wireless client connectivity

The exhibit shows the current plan for the topology.
Which change should the architect make to the plan to provide better support for the customer availability requirements?

Question11: A customer requires new MCs for a large multi-site network with about 600 AP-345s and 30,000 wireless clients. The customer requires redundancy for the MCs with each MC being able to handle the full load in a failover situation. The network should be able to sustain the loss of a controller with stateful failover within seconds. It should be able to undergo software upgrades without downtime.
The architect has recommended two 7240XM MCs. The customer points out that 7220 MCs can support enough APs and wonders why the architect recommended the 7240XMs.
What should the architect explain?

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.)

Question13: In which of these scenarios do the customer requirements point towards tunneled node, or dynamic segmentation, on AOS-Switches?

Question14: 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?

Question15: 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?

Question16:
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.

How many AirWave licenses does the architect need to add?

Question20: 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?

Question21: A university has a dormitory with several floors. Currently APs are deployed in the hallways about every 50 feet (15m). The university has several issues with the existing network:
Students complain that the network is very slow, and the wireless signal is poor.

Students want to connect some equipment such as gaming consoles and IP TVs on Ethernet, but the

dorm rooms just have one Ethernet port.
How does the deployment of AP303Hs resolve the customer issues?

Question22: 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?
