HPE6-A47 Online Practice Questions and Answers

An architect plant to purpose an Aruba wireless solution with several Mobility Controllers (MCs) and a Mobility Master (MM) architecture. Wireless users run Skype for Business, a Unified Communications (UC) solution. The architect plans to use the Aruba SDN capabilities to integrate with the UC solution.

What helps to support high availability specifically for the SDN services?

A. a redundant master MC

B. backup controllers defines on the APs

C. a cluster deployment for MCs

D. a redundant MM

An architect learns that a customer site is 14,307 square meters (154,000 square feet) and supports 900 employees using WiFi 5 Ghz radio. What additional information should the architect collect to create the RF plan?

A. number of devices used by each user

B. the OS used on wireless devices

C. whether BLE wayfinding is required

D. software version on Mobility Controllers (MCs)

What typically drives the need for an aggregation layer in modern networks?

A. insufficient fiber cabling, especially between buildings

B. lack of high speed uplink capabilities at the access layer

C. simplification of spanning tree protocol ad the access layer

D. need to extend VLANs across wider areas

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

A customer has very high availability requirements for wireless services. The architect plans to implement clustering on several Aruba Mobility Controllers (MCs).

Which benefit of this feature should the architect explain?

A. Clustering provides wireless client load balancing and seamless failover for client sessions.

B. Clustering provides high stability because one MC is active for all sessions and one is standby for all sessions.

C. Clustering enables an AP with a failed MC to operate on its own briefly to ensure seamless connectivity.

D. Clustering enables an AP with a failed MC to reconnect to a new AP after a short bootstrap.

An architect needs to plan an 802.11ac wireless upgrade for a university building. What is one reason that it is important for the architect to identify auditoriums?

A. Auditoriums typically require a high-density AP design for RF coverage.

B. Users in Auditoriums often have Bluetooth devices, which can be a source of interface in the 5 GHz band.

C. Auditoriums typically require the use of 80 MHz channels to meet bandwidth requirements.

D. Auditoriums often require the use of DFS channels for sufficient 20 MHz channels.

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?

A. Assign access layer switches IP addresses on a VLAN that is dedicated for switch management.

B. Ensure that DHCP is enabled on only the switch Default VLAN.

C. Ensure that Telnet is enabled and set to listen on production VLANs.

D. Assign switches static IP addresses on the same VLAN on which APs are deployed.

An architect plans where to deploy new Aruba 320 Series APs at a customer site. The architect plans for the APs to be installed on the ceiling where power is inaccessible. The Ethernet cable run to these locations is CAT6, and the customer wants to support at least 1 GbE connectivity. The architect plans to connect each AP with one Ethernet port to a switch in a nearby wiring closet.

Which feature does the switch need to support for this deployment?

A. PoE+

B. LACP

C. Port channel

D. Smart Rate

Which benefit does Aruba AirWare Clarity provide to customer IT staff?

A. assesses times for clients to obtain DHCP and DNS services to help staff diagnose non-WiFi related issues

B. create a heat map of RF coverage, shows places with interfaces, and helps staff pinpoint the interference source

C. provides insight into the security posture of clients connected to the network, whether wired or wireless

D. maps all network devices, including APs, MCs, switches, and client devices, and provides information about each node

An architect simulates VoIP calls and tests the throughput as 67 Kbps, packet loss as 0.3 percent, maximum latency as 100 ms, and maximum jitter as 100 ms.

Which issue typically causes a poor experience for users?

A. the packet loss

B. the throughput

C. the latency

D. the jitter
