HPE6-A47 HP Exam Questions and Free Practice Test

Question 7

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 tunnelled node on Aruba 2930M switch ports that connect to laptops. What is one advantage of this form of authentication?

A. ensures that Aruba firewall policies apply to wired user traffic.

B. prevents users from connection attempts with more than three devices

C. enables user access control and ensures only authorized users connect.

D. provides a second layer of protection for wireless users at the internal perimeter

Correct Answer:C

Question 8

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 2.4 GHz band

B. a signal of -75 dBm in the 5 GHz band

C. a signal of -65 dBm in the 5 GHz band

D. a signal of -75 dBm in the 2.4 GHz band

Correct Answer:C

Question 9

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?

A. 1

B. 6

C. 12

D. 25

Correct Answer:B

Question 10

An Aruba wireless solution for a very high density (VHD) wireless solution consists of a Mobility Master (MM) and two Mobility Controllers (MCs). What is the best practice design for routing the wireless traffic?

A. The MCs provide the default gateway services for wireless devices and use static routers.

B. The MCs act at Layer2, and the MM acts as the default gateway.

C. The MCs act at Layer2, and core routing switches act as the default gateway.

D. The MCs provide the default gateway services for wireless devices and use OSPF.

Correct Answer:B

Question 11

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:
HPE6-A47 dumps exhibit 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 switche

D. Extend the VLANs to the core.

E. 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

Question 12

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?

A. the need for high speed 10 GbE ports

B. the need for clustering

C. the number of devise required

D. the number of APs required

Correct Answer:C
