Question1: An architect needs to choose between an Aruba Mobility Controller (MC) 7010 or 7024. Which customer need indicates that the 7024 is a better choice than the
7010?

Question2: For which scenario does an Aruba VIA client provide the solution?

Question3: The customer has an office environment with users who have laptops that can connect with wired or wireless. Users also bring one or two of their own devices. An architect creates a proposal with Aruba AP-325s, 7210 Mobility Controllers (MCs), a Mobility Master (MM), and Aruba 2930M switches at the access layer to support the laptops and APs.
The architect plans to recommend 802.1X authentication without tunneled node on Aruba 2930M switch ports that connect to laptops. What is one advantage of this form of authentication?

Question4: A customer needs a wireless refresh for 802.11ac. The customer site has about 3,000 wireless devices, and the network architect plans to propose 200 APs. The architect also plans to propose two Virtual Mobility Controllers (VMCs) and a Virtual Mobility Master (VMM). Which licenses should the architect propose for this solution?

Question5: A customer needs a networking solution that supports their Microsoft Skype for Business Unified Communications (UC) solution. The architect plans to use multiple Aruba APs, switches, and controllers.
The customer wants real time statistics and assessment of call quality. Which component should the architect include to provide these services?

Question6: What typically drives the need for an aggregation layer in modern networks?

Question7: A customer has a small office building that needs approximately 32 APs. The solution must support basic rogue AP detection and provide a stateful firewall with role-based policies. The customer would like the simplest, most cost-effective deployment that meets their needs.
What should the architect recommend?

Question8: Refer to the exhibit.

An architect needs to plan a network solution for a new office building with four floors. Each floor has two wiring closets with the equipment shown in the exhibit.
The switches will connect to employee desktops, a few campus APs controlled by MCs, and printers. The switches do not implement tunneled node.
What is a best practice design for the VLANs and subnets for the wired devices?

Question9: An architect plans where to deploy new Aruba 320 Series APs at a customer site. The architect plans for the APs to be installed on the ceiling where power is inaccessible. The Ethernet cable run to these locations is CAT6, and the customer wants to support at least 1 GbE connectivity. The architect plans to connect each AP with one Ethernet port to a switch in a nearby wiring closet.
Which feature does the switch need to support for this deployment?

Question10: 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?

Question11: 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?

Question12: For which scenario should an architect recommend Aruba Central Managed Portal (MSP)?

Question13: Refer to the exhibit. The customer needs to expand its wired and wireless network to a new building, Building 2, which is near the existing building, Building 1. The exhibit shows the logical plan that the architect has created so far. The aggregation layer switches in the new building should provide the default gateway services for the VLANs in the new building and route traffic to the core. The existing Aruba Mobility Controllers (MCs) will control the new APs.

What should be the VLAN assignment for Link 1, indicated in the exhibit?

Question14: What should an architect use as a guideline to determine when to define another VLAN for wireless devices?

Question15: 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?

Question16: An architect needs to plan the RF coverage. Which application has the greatest potential impact on RF design?

Question17: 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?

Question18: An architect proposes Aruba 2930F switches, which do not have OOBM ports. The customer wants to follow best practices for network management security.
Which guideline can the architect follow?

Question19: 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?

Question20: An architect simulates VoIP calls and tests the throughput as 67 Kbps, packet loss as 0.3 percent, maximum latency as 100 ms, and maximum jitter as 100 ms.
Which issue typically causes a poor experience for users?

Question21: A customer has high security needs, so the network architect proposes dedicated Air Monitors (AMs). What is one additional benefit of the AMs that the architect can explain?

Question22: 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?

Question23: Refer to the exhibit. What is one reason for an architect to recommend the use of Virtual Switching Framework (VSF) in this network?

Question24: An architect plans to purpose two Aruba Mobility Controllers (MCs) in a cluster. The customer has a large building that needs to support about 10,000 devices.
The architect plans to associate the Employees WLAN with VLAN ID 10.
What is one Aruba best practice for this design?
