What is the purpose of Mesh Clusters?

• A.To define a group of mesh APs that create mesh links with each other.
• B.To enable mesh APs to join the nearest mesh portal cluster.
• C.To separate Mesh points from Mesh Portals.
• D.To ensure that mesh APs with the same VAPs are not in the same cluster.
• E.To cluster mesh APs of the same model together.

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 5 GHz band
• B.a signal of -75 dBm in the 2.4 GHz band
• C.a signal of -75 dBm in the 5 GHz band
• D.a signal of -65 dBm in the 2.4 GHz band

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:
* 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 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. Based on the plan for wired authentication, what is a correct plan for wired
user VLANs?

• A.use the MCs to assign wired users to their VLANs, and extend the VLANs to a Layer 3 switch
  connected to the MC
• B.configure the same roles on switches and MCs to place wired and wireless users in the same VLANs.
  Extend VLANs from access layer switches to the core.
• C.specify the VLANs in network policies on AirWare, and ensure that both the switches and MCs are
  managed by AirWare
• D.assign wired users to different VLANs from wireless users, based on port or role assignments on access
  layer switches. Extend the VLANs to the core.

Which guidelines should an architect use to determine how many AirWave servers to recommend?

• A.One server should be deployed on every subnet with an infrastructure device.
• B.One server should be dedicated to the wired infrastructure and one server to the wireless infrastructure.
• C.One server should monitor and manage up to about 4,000 infrastructure devices.
• D.One server is recommended for the base features and one server each for add-on features such as
  Clarity.
