HPE6-A47 sample questions

Question 1

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?

Accepted Answer

PoE+

Answer

Port Fast

Answer

Port channel

Answer

Smart Rate

Question 2

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?

Accepted Answer

BGP

Answer

OSPF graceful restart

Answer

SmartLink

Answer

VRRP

Question 3

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?

Accepted Answer

a redundant MM

Answer

a redundant master MC

Answer

backup controllers defines on the APs

Answer

a cluster deployment for MCs

Question 4

What is one important guideline for antenna selection?

Accepted Answer

Ensure that the antenna is designed for the frequency used by the radio.

Answer

Ensure that the beam-width exceeds 100 degrees.

Answer

Ensure that the H-plane and E-plane values are within 45 degrees of each other.

Answer

Ensure that the beam-width does not exceed 100 degrees.

Question 5

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

Accepted Answer

number of devices used by each user

Answer

the OS used on wireless devices

Answer

whether BLE wayfinding is required

Answer

software version on Mobility Controllers (MCs)

Question 6

A customer needs an 802.11 ac upgrade for an office with cubicles. The customer states that, because they planned locations for the existing 802.11 n APs so that there are no coverage holes, they will simply deploy the new 802.11ac APs in the same location as the existing APs. The customer plans to support mobile devices in addition to laptops.

What should the architect explain about why a site survey is desirable to determine the optimal locations for the new APs?

Accepted Answer

An 802.11ac deployment typically works better with side-mounted, rather than ceiling-mounted, APs, and a site survey will help determine the new mounting locations.

Answer

The new 802.11 ac deployment should have a capacity-based design for the best performance, but the existing deployment sounds like a coverage-based design.

Answer

802.11ac AP radios tend to be more sensitive to 2.4 GHz interference than 802.11 n APs, so the architect needs to search for all potential sources of such interference.

Answer

802.11 ac APs can support a higher density of clients, so they can be deployed farther apart than the APs in most existing 802.11 n deployments.
