HPE6-A49: Aruba Certified Design Expert 8 Written Exam

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?

Change the SR transceivers for each link between the writing closet switches and the network core to LRM transceivers.
Add an aggregation layer, and connect writing closet switches to the aggregation layer on Smart Rate ports.
Add an aggregation layer, and connect writing closet switches to the aggregation layer with SFP+ SR transceivers.
Add a mode conditioning cable for each link between the writing closet switches and the network core.

Correct answer: D

What is one customer requirement that can drive the need for a relatively dense AP deployment, in which the coverage areas of at least three AP radios overlap?

support for beacon management
AP operation as hybrid AMs for IDS/WIPS
the deployment of dual 5GHz radio APs
location tracking of wireless IoT devices

Correct answer: D

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?

Correct answer: B

A customer has an existing Aruba network, which currently supports up to 9,000 wireless client devices.

The existing network includes these components:

Four 7210 MCs
Five 7030 MCs
200 AP-303HRs
300 AP-345s

The customer wants to convert to an ArubaOS 8.x architecture. The architect plans to deploy a virtual MM.

Which exhibit shows the correct BOM for the MM?

Correct answer: C

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?

CAPs and branch office controllers with an SD-WAN license
IAPs and no branch office controllers
CAPs and branch office controllers
RAPs and no branch office controllers

Correct answer: B

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?

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

Correct answer: D

An indoor sports stadium has 5,000 seats in two rings:

The stadium has a ceiling height of 60 feet (18m).
There is a catwalk around the perimeter of the court, between the court and the seating areas. This catwalk is 40 feet (12m) from the floor.
There are two scoreboards at either end of the stadium.
The construction of the stadium is concrete and steel.

The customer does not want an under-seat, pico cell deployment, and the customer requires 802.11ac Wave 2.

Which AP model is appropriate to provide coverage in the main stadium bowl?

AP-228
AP-344
AP-365
AP-375

Correct answer: A

Refer to the exhibit.

A customer has a wired infrastructure shown in the exhibit. The customer is in the process of expanding their wireless services.

They will now add a new wireless solution, with mobility controllers (MCs) connected as shown.

The new wireless solution will support a total of 450 APs and about 26,000 wireless devices.

It must provide seamless roaming across the entire campus.

After the new deployment, both wired and wireless devices experience IP connectivity issues.

Which change to the existing infrastructure should the architect recommend to support all of the customer requirements?

The MCs should be moved to the aggregation layer, and more MCs added.
The core and aggregation switches should disable Virtual Switching Framework (VSF).
The core switches should be replaced with switches that have larger ARP tables.
The wired VLANs should be combined into a single VLAN and /16 subnet.

Correct answer: B

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?

This solution will require about 6 battery-powered beacons, which can be managed by the APs.
While these APs cannot act as beacons, they have a USB slot that accepts USB beacons.
The customer can enable the built-in BLE capability in the AP-335 radio to meet these requirements.
The customer must remember to purchase a Meridian Maps license with the Campaigns license.

Correct answer: A

Refer to the exhibit.

A hotel needs a wireless solution. The architect has selected 303H Series, controlled by a local MC, as the best choice.

The hotel plans to have the APs installed in the existing wall boxes which have one Ethernet port each.

The architect has created to BOM shown in the exhibit. (Note that this portion of the BOM does not include the MC, which is not part of this question.)

Which additional clarification should the architect seek to determine whether this BOM fully meets the customer needs?

whether the hotel wants to deploy the APs as RAPs or CAPs
whether the hotel has CAT5e patch cables long enough to reach the boxes
whether directional or omnidirectional external antennas work better for the APs
whether the hotel already has a PoE or PoE+ source
