Exhibit 1. Existing wiring plan:

Exhibit 2. Current proposal:

A customer has a building that needs a switch upgrade. The customer would like at least 20Gbps for the

uplink bandwidth out of each closet. The building writing plan is shown in Exhibit 1. The customer will not

consider any cable upgrades at this point. The current proposal is shown in Exhibit 2.

Which correction must architect make to the proposal to meet the customer requirements?

A. Change the SR transceivers for each link between the writing closet switches and the network core to LRM transceivers.

B. Add an aggregation layer, and connect writing closet switches to the aggregation layer on Smart Rate ports.

C. Add an aggregation layer, and connect writing closet switches to the aggregation layer with SFP+ SR transceivers.

D. Add a mode conditioning cable for each link between the writing closet switches and the network core.

A hospital needs a wireless solution which will provide guest access for patients and visitors, as well as for medical staff. In addition to laptops and tablets, staff have wireless voice communicator devices. Some medical equipment also connects wirelessly.

How can the network architect help to ensure that patient and visitor internet use does not interfere with more vital hospital applications?

A. Deploy IntroSpect to monitor patient and visitor traffic.

B. Plan a bandwidth contract for the guest role in the MC firewall.

C. Deploy dedicated Air Monitors (AMs) at about one-fourth the density of APs.

D. Ensure that the guest SSID has a password associated with it.

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. The 5406R switches are in a VSF fabric; each switch has redundant power supplies, but not redundant management modules.

B. The 5406R switches are not in a VSF fabric; each switch has redundant power supplies but not redundant management modules.

C. The 5406R switches are not in a VSF fabric; each switch has redundant power supplies and redundant management modules.

D. The 5406R switches are in a VSF fabric; each switch has redundant power supplies and redundant management modules.

A retailer currently has two redundant ClearPass C2000 DL360 Gen9 hardware appliances and two perpetual 1K Access licenses. The customer uses ClearPass to authenticate employee wireless devices and other corporate wireless devices. ClearPass logs indicate that peak license usage is currently 1900. The customer now wants to add a guest access solution. Guests will connect to an open SSID and redirected to a portal which they can use to self-register and log in. The customer anticipates that up to 1550 guest devices will connect at the same time.

The customer requires the most cost-effective solution that will meet the requirements. What should the network architect recommend for this solution?

A. Two 1K Guest licenses

B. 1K+500 Access licenses; Two 1K Onboard licenses

C. 1K+500 Access licenses

D. 1K+500 Access licenses; 1K+500 Guest licenses

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?

A. AOS-Switches can meet the uplink bandwidth needs with an extensive array of choices for transceivers.

B. Aruba PoE+ ports can provide more than 30W of power even to APs at the fat end of the floor.

C. Aruba Smart Rate ports enable switches to achieve the required uplink speeds without expensive re-cabling.

D. Aruba conditioning mode cables enable 10GbE SFP+ of 40GbE QSFP+ connections on copper cabling.

A customer has an existing Aruba wireless solution to provide wireless access for employees. The solution includes APs, mobility controllers (MCs) at the network core, and a Mobility Master (MM). A customer would like to set up a separately managed guest network and have the traffic go directly to the DMZ.

What should the architect suggest as the simplest solution that meets the requirements?

A. Add APs in a dedicated AP group to support only the guest network SSID.

B. Have a dedicated mobility controller in the DMZ managed by the same MM.

C. Double the number of APs and controllers

D. Use MultiZone, and put a mobility controller in the DMZ.

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 62,000

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.

What is one change to the existing network that the architect should recommend to meet the new customer requirements?

A. upgrade to at least CAT7 cable for all the wired drops

B. upgrade to MM OM3 fiber between the floors

C. new aggregation layer switches to support larger ARP tables

D. new access layer switches to support PoE+

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?

A. The 7240XMs MCs are required to support the large number of wireless clients in this network.

B. The 7240XMs MCs support 40GbE ports, which are desirable for future proofing.

C. The 7240XMs MCs can support full CPSec tunnels with this number of APs, while the 7220 MCs cannot.

D. The 7240XMs MCs have more advanced clustering and availability capabilities than the 7220s MCs.

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.

A hospital needs a better way to track its inventory, including wireless medical devices that are moved

around the site a lot.

Which solution meets these needs?

A. Aruba asset tags and beacons

B. Aruba asset tags, APs, and Meridian

C. Aruba beacons, APs, and AirWave

D. Aruba beacons and Meridian
