HP Aruba Certified Design Professional - HPE6-A47 Exam Practice Test
An architect plans 12 APs for an auditorium that is 325 square meters (3, 498 square feet). Each AP has one
2.4 GHz radio and one 5 GHz radio. Both types of radios use 20 MHz channels.
Assume that DFS channels can be used in this design. How many 5 GHz collision domains does this design provide?

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: specify the VLANs in network policies on AirWare, and ensure that both the switches and MCs are managed by AirWare C: 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.
D: 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.

D: 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.
Correct Answer:
C
Explanation:
This answer is correct because it meets the customer's requirements for wired authentication and traffic forwarding. By assigning wired users to different VLANs from wireless users, the architect can ensure that the wired traffic is not tunneled to the MCs, but forwarded locally on the access layer switches. This reduces the load on the MCs and the network bandwidth. By using port or role assignments on the access layer switches, the architect can also implement 802.1X authentication without tunnelled node, which enables user access control and dynamic VLAN assignment based on user identity and device type. By extending the VLANs to the core, the architect can ensure that the wired users can reach the data center and other network resources through the Layer 3 switch connected to the firewall.

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?
