Demo Questions
Question 1
Refer to the exhibits.
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
Question 2
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
Question 3
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
Question 4
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
Question 5
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
Question 6
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
Question 7
A customer has phones used as wireless Voice over IP (VoIP) devices.
Which is one implication for the design?
- Plan policies for the phone role on MCs to give the phones a high QoS priority.
- Ensure a -75 GHz signal in both the 2.4GHz band and the 5GHz band across the entire site.
- Ensure that APs connect on Smart Rate ports to support the high bandwidth demands of the phones.
- Apply a bandwidth contract to the phone VLAN to limit broadcast and multicast traffic.
Correct answer: C
Question 8
Refer to the exhibit.
A mall has an existing Aruba solution with 15 AP-335s. The mall now wants to add Meridian and location-based services, in particular blue dot wayfinding. The customer plans to use the built-in beacon in the existing AP radios. These Meridian licenses have been proposed:
- 1x Aruba Meridian Maps
- 1x Aruba Meridian Blue Dot Nav
Which concern should the architect raise about this plan?
- Separate beacons should be deployed to provide proper coverage for wayfinding.
- Only the Blue Dot Nav license is required to meet the customer requirements.
- The customer requires wireless sensors to manage the beacons in the AP radios.
- The existing AP radios do not support beacon functionality.
Correct answer: A
Question 9
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?
- Clustering on MCs and VRRP on Core switches
- VRRP on MCs and VSF on Core switches
- VRRP on both MCs and Core switches
- Clustering on MCs and VSF on Core switches
Correct answer: A
Question 10
Refer to the exhibit.
A customer needs a wired network upgrade and has complained about performance issues. The architect has collected information about traffic flow on several switch ports in different locations across the network, and the results are shown in the exhibit. Each of these ports is a 1Gbps port.
What can the architect conclude?
- None of these ports show any periods of congestion.
- Port 1 shows periods of congestion, other ports are not congested.
- Port 3 shows periods of congestion, other ports are not congested.
- All of the ports show serious congestion.
