HPE6-A47 Online Practice Questions and Answers

An architect needs to plan the bandwidth for two Aruba 7240 Mobility Controllers (MCs) which will connect to the network core. The customer indicates that four 10 GbE links between the network core and the data center will be adequate. The customer expects almost all traffic in the network will be wireless. The customer expects up to 25 Gbps upstream traffic from wireless clients and up to 35 Gbps downstream to wireless clients. The customer requires the MCs to be able to continue to forward traffic if up to one link fails, but lower performance during the failover situation is permissible.

What are the minimal links to meet these requirements?

A. two 10 GbE links on each of the MC

B. two 40 GbE links in each of the MCs

C. three 10 GbE links on each of the MCs

D. four 10 GbE links on each of the MCs.

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?

A. an unused VLAN such as 200

B. VLANs 21, 22, and 23 only

C. VLANs 11, 12, 13, 21, 22, and 23

D. the default VLAN and VLAN 14

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?

A. the need to support 2000 users or devices

B. the need to support PoE+

C. the need to manage 20 APs

D. the need to connect 20 APs directly to the MC

Refer to the exhibit.

The customer requires fast failover if any one link or core device fails.

Which additional technology should the architect plan on the core VSF fabric to meet these criteria?

A. OSPF graceful restart

B. SmartLink

C. BGP

D. VRRP

An RF plan specifies wide sector directional antennas.

Refer to the antenna specifications.

H-plane refers to the Azimuth or Horizontal plane and E-plane refers to Elevation or Vertical plane.

Antenna 2: H-plane = 360; E-plane = 60

Antenna 3: H-plane = 100; E-plane = 90

Antenna 4: H-plane = 60; E-plane = 60

Which antenna specifications indicate that the antenna is a good choice for the plan?

A. Antenna 1

B. Antenna 2

C. Antenna 3

D. Antenna 4

A customer needs a wireless solution upgrade. Among the devices that need wireless access are printers. What information about the printers does the architect need to plan the wireless solution? (Select two.)
