A financial institution has an Aruba wireless system. Each floor is 19 meters by 23 meters (200 feet by 250 feet) and has 20 APs. The organization now requires dedicated Air Monitors (AMs).

About how many AMs should the architect recommend per floor?

A. about 1 or 2 per floor

B. about 3 to 5 per floor

C. about 10 to 12 per floor

D. about 16 to 20 per floor

Read this scenario thoroughly, and then answer each question that displays on the right side of the screen.

An architect proposes these products for a customer who wants a wireless and wired upgrade:

1.

Aruba 2930M switches at the access layer

2.

Aruba 5406R switches at the core

3.

Aruba AP-325s

4.

Aruba 7205 Mobility Controllers (MCs), deployed in a cluster

5.

Aruba Mobility Master (MM)

6.

Aruba ClearPass Cx000V

7.

Aruba AirWare

The architect also needs to propose a security plan for the solution. The customer has 900 employees and up to 30 guests a day. The customer wants to protect the internal perimeter of the network with authentication and simple access controls. The customer is most concerned about wireless security, but also wants to ensure that only trusted users connect on the wire. However, the customer also wants all wired traffic to be forwarded locally on access layer switches. The customer already has a third-party firewall that protects the data center.

The customer wants to use certificates to authenticate user devices, but is concerned about the complexity of deploying the solution. The architect should recommend a way to simplify. For the most part users connect company-issued laptops to the network. However, users can bring their own devices and connect them to the network. The customer does not know how many devices each user will connect, but expects about two or three per-user. DHCP logs indicate that the network supports a maximum of 2800 devices.

Refer to the provided scenario.

Which solution should the architect recommend on the 2930M switches to authenticate and control wired employee devices?

A. MAC-Auth on edge ports and no tunneled node

B. 802.1X on edge ports and per-user tunneled node

C. 802.1X on edge ports and no tunneled node

D. Mac-Auth on edge ports and per-user tunneled node

An architect needs to plan a wireless deployment. The architect conducts a physical walkthrough, but still needs more information.

Which significant RF obstacle can be difficult to see visually and might require access to blueprints?

A. fiberglass

B. metal firewall

C. ceiling tiles

D. drywall

An enterprise needs an upgrade to 802.11ac. Users run applications such as Web, email, voice, and video. The architect needs to conduct an active site survey to plan 802.11ac AP locations. The noise floor is about -90 dBm across the site.

Based on Aruba best practices, what is the minimum acceptable signal that the architect should look for to determine the test AP range?

A. a signal of -65 dBm in the 2.4 GHz band

B. a signal of -75 dBm in the 5 GHz band

C. a signal of -65 dBm in the 5 GHz band

D. a signal of -75 dBm in the 2.4 GHz band

A customer needs an 802.11ac upgrade for an office with cubicles. The customer states that, because they planned locations for the existing 802.11n APs so that there are no coverage holes, they will simply deploy the new 802.11ac APs in the same location as the existing APs. The customer plans to support mobile devices in addition to laptops.

What should the architect explain about shy a site survey is desirable to determine the optimal locations for the new APs?

A. An 802.11ac deployment typically works better with side-mounted, rather than ceiling-mounted, APs, and a site survey will help determine the new mounting locations.

B. The new 802.11ac deployment should have a capacity-based design for the best performance, but the existing deployment sounds like a coverage-based design.

C. 802.11ac AP radios tend to be more sensitive to 2.4 GHz interference than 802.11n APs, so the architect needs to search for all potential sources of such interference.

D. 802.11ac APs can support a higher density of clients, so they can be deployed farther apart than the APs in most existing 802.11n deployments.

A customer has several clusters of Aruba 325 Instant APs. The customer is happy with the performance of the current APs, but would like to add a Mobility Controller (MC).

What should the architect propose?

A. the purchase of Universal APs that are the same modes as the current APs.

B. Aruba ClearPass to onboard the APs as campus APs in the new MC-based deployment

C. conversion of the existing Instant APs to campus APs (CAPs)

D. a Virtual Mobility Controller (VMC) which can be licensed to control Instant APs

Refer to the exhibit.

The exhibit shows the current plan for a wired network upgrade.

As much as possible, the customer wants to flatten the architecture and avoid recabling. However, each Building 2 switch must also maintain connectivity to the core if one link fails.

What should the architect propose to meet the customer requirements?

A. Use two additional 2930F switches to act as an aggregation layer for Building 2; connect them to the core on 40 GbE connections.

B. Connect each Building 2 switch directly to the core on a single fiber strand through the use of SFP+-SR transceivers.

C. Combine the switches in each Building 2 closet as a VSF fabric; establish two 10 GbE connections to the core per fabric.

D. Extend additional fiber between the buildings so that each Building 2 switch can have a direct 10 GbE connection to the core.

Refer to the exhibit.

A customer wants to replace the core and aggregation layer of an existing network. Currently the network routes between the aggregation layer and core, and uses the technologies shown in the exhibit.

The customer now wants to route at the core, instead of the aggregation layer, and extend some of the same VLANs in different buildings.

However, the customer cannot eliminate the aggregation layer at this point. What should the architect recommend?

A. Create a backplane stack at the aggregation layer and a VSF fabric at the core.

B. Implement broadcast filtering on switch-to-switch links across all of the buildings.

C. Combine all switches in the aggregation layer and core into a single backplane stack.

D. Use VRRP on the core and aggregation switches, with the aggregation switches acting as standby.

An architect plans to deploy a Mobility Controller (MC) at one building in subnet 10.23.01.0/24 and another MC in another building in subnet 10.44.12.0/24. The MCs need to provide redundancy for each other.

What must the architect take into account in the redundancy plan?

A. The MCs cannot provide any level of redundancy for each other unless one is moved into the other's subnet.

B. The MCs cannot be in a cluster, and they must use Virtual Router Redundancy Protocol (VRRP) to provide redundancy for each other.

C. The MCs can be in a cluster, but the cluster will not support features such as stateful failover.

D. Each MC can be the backup LMS for the other MCs' APs, but it cannot be in a cluster with the other MC.

Refer to the exhibit.

A customer needs to upgrade the wireless network at their campus, which has a single large building. Employees use the wireless network to access the Internet and centralized services. The building has four floors. These are the requirements: 30 APs on each floor A Mobility Master (MM)-based architecture Deployment of one Aruba 7030 Mobility Controller (MC) on each floor, with the MCs combined in a cluster for seamless client failover and roaming

What should the architect explain to the customer about the proposed solution?

A. MCs should be deployed centrally on the same VLAN to better meet these goals

B. MCs in a cluster must have additional AP licenses to support APs of a failed controller

C. The MC 7030 does not support enough APs for the requirements

D. The MC 7030 only supports clusters with up to three members
