NO.13 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?

NO.14 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?

NO.15 What is the purpose of Mesh Clusters?

NO.16 Read this scenario thoroughly, and then answer each 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?

NO.17 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?

NO.18 An architect plans 128 APs to support 12,800 devices in a very high density (VHD) design. The customer
requires high availability, so the architect plans to recommend a pair of controllers. What is one reason to
recommend 7210 controllers rather than 7205 controllers for this deployment?

NO.19 An architect proposes an Aruba solution with a hardware Mobility Master (MM) to a customer. The customer has a disaster recovery site which is connected to the main site at Layer 3. The customer requires the MM to remain available in case of a total site failure.
Which plan meets the customer requirements?

NO.20 Scenario:
An architect proposes these products for a customer who wants a wireless and wired upgrade:
* Aruba 2930M switches at the access layer
* Aruba 5406R switches at the core
* Aruba AP-325s
* Aruba 7205 Mobility Controllers (MCs), deployed in a cluster
* Aruba Mobility Master (MM)
* Aruba ClearPass Cx000V
* Aruba AirWave

NO.21 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?

NO.22 A customer requires high availability for wireless services, including stateful failover for user connections if the Mobility Controller (MC) that handles the user traffic fails. What is the requirement for the design?

NO.23 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?

NO.24 An architect has an Instant AP (IAP) cluster at a mid-sized branch office. The IAP cluster now needs to tunnel corporate traffic to a Mobility Controller (MC) at the main office. However, the branch office should remain functional even if the link to the main office fails. Users at the branch office require access to main office resources, but do not require multicast services.
What is the recommended DHCP mode?

NO.25 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?

NO.26 Fast Failover has been implemented between Local 1 and Local 2 separated by Routers. During testing Local1 was disabled and all Campus APs backed up to Local 2 flawlessly. But the RAPs did not, they all failed.
What could be the cause?

NO.27 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?

NO.28 An architect needs to plan 802.11ac wireless deployment for an office environment with a mix of closed offices and cubicles. The coverage area is approximately 4,645 square meters (approximately 50,000 square feet) and has 350 users. The employees use the wireless network for typical office applications, such as email, Web, printing, and accessing shared files and datacenter services.
The architect plans to do a predictive site survey and use VisualRF to plan the coverage. What is a general estimate for the AP count that the architect should have in mind?

NO.29 Refer to the exhibit. An architect selects 5406R switches for the aggregation layer. What is an appropriate amount of bandwidth for the link aggregation between each aggregation layer VSF fabric and the campus core?

NO.30 Refer to the exhibit.
