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.

An architect has recommended the deployment or RAPs at user home offices to provide access to the corporate LAN.

How should the architect plan the SSID for the RAPs?

B. any name for the SSID with MAC-Authentication

C. any name for the SSID, which would be open; VIA is used for security

D. same name used for the corporate SSID, but always with WPA2-Personal security

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?

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 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?

A. They are specialized to provide wireless coverage for single-room deployment and also provide wired ports for clients.

B. They are specialized for wireless meshing, which conserves Ethernet ports, and for high-speed wireless services.

C. They have high-gain antennas designed for older buildings and support Smart Rate for high bandwidth on one port.

D. They have directional antennas that will improve the wireless signal and require just one Ethernet port.

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?

A. 1 MM-VA-500; 2 MC-VA-250; 540 Enterprise licenses

B. 1 MM-VA-500; 1 MC-VA-250; 180 Enterprise licenses

C. 1 MM-VA-1K; 2 MC-VA-250; one Enterprise license

D. 1 MM-VA-1K; 1 MC-VA-250; 180 Enterprise licenses

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

A. A customer has wired IoT devices and wants to be able to control their access. The architect recommends sending all of their traffic through the MC role-based firewall.

B. A customer wants to manage their AOS-Switches in a more centralized manner. They would like to connect AOS-Switches to AirWave over secure IPsec tunnels and control all configuration from there.

C. A customer has a branch office with an AOS-Switch and an Internet connection. The customer would like to give branch office users secure access to the corporate LAN over an IPsec tunnel.

D. A customer lacks physical security and wants to impose 802.1X authentication on wired ports. After employees complete 802.1X authentication, they should receive full access to the network.

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.

Case study

A customer needs a wireless network upgrade for 802.11ac and possibly an upgrade to the wired network.

The customer requires dual-radio 802.11ac APs, each radio of which can support 4x4 MIMO at full feature

set.

The customer has given architects this information about their wireless devices:

2700 IoT devices which will have only wireless connections; they support WPA2 with 802.1X

300 on each floor in 3 buildings with 3 floors each

5,400 users, who use devices such as laptops and smartphones

600 users on each floor in 3 buildings with 3 floors each

24 security cameras which will have only wireless connections; they support WPA2 with 802.1X and have

a local power source

4 on floor 1 of each of the 3 buildings

2 on the other 6 floors

The architect also has collected information about the existing wired network.

The existing access layer switches support these features:

10/100/1000 edge ports

PoE (802.3af)

1GbE fiber uplinks

The existing aggregation switches support these features:

1/10GbE fiber ports

ARP tables up to 64,000

The customer has provided this figure that shows the existing cabling between floors and between

buildings:

Each floor is about 100 feet (30 m) by 140 feet (43 m) with a 10 foot (3 m) ceiling. Interior walls are drywall. The layout for each floor is similar to that shown below. CAT5e cable is extended to all areas.

The customer wants to have a wired upgrade as well. The customer has indicated some additional requirements for the wired network, including redundancy for all switch-to-switch links. The customer also wants to explore whether the aggregation layer in buildings can be eliminated.

What is one missing piece of information the architect should obtain from the customer before they design the solution and select new switches and their accessories?

A. the power requirements on the wireless security cameras

B. the number of fiber strands for fiber runs

C. the percentage of time that employees use their wired connection

D. the power rating on the fiber deployed between buildings

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. one MCs for the airport, one MC for airport security, and one MC for each of the four airlines with its own SSID, all controlled by the same MM

B. one MCs for the airport, a cluster of MCs for airport security controlled by a pair of MMs, and one MC for each of the four airlines

C. a cluster of MCs for the airport, a cluster of MCs for airport security, and one MC for each of four airlines, all controlled by the same MM pair

D. a cluster of MCs for the airport controlled by an MM pair, a cluster of MCs for airport security controlled by a different MM pair, and one standalone MC for each of the four airlines.
