HPE6-A47 sample questions

Question 1

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 2

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.

Question 3

Refer to the exhibit.

Exhibit 1.

Exhibit 2.

Exhibit 1 shows the logical plan, and Exhibit 2 shows the BOM that the administrator has made in Iris. What is missing from the IRIS BOM?

Accepted Answer

stacking modules and cables

Answer

stacking licenses

Answer

10 GbE direct attach cables

Answer

an uplink module for one of the switches

Question 4

A customer currently has an Instant AP deployment. Which customer requirement would indicate that the customer needs to add a controller to the deployment?

Accepted Answer

the requirement for a cloud-based management solution

Answer

the requirement to apply role-based firewall policies

Answer

the requirement for a captive portal for guests

Answer

the requirement to provide client-to-site VPN access for remote users

Question 5

What should an architect use as a guideline to determine when to define another VLAN for wireless devices?

Accepted Answer

the employee roles, with a different VLAN for each role or department

Answer

the WLAN or SSID, with a different VLAN for each SSID

Answer

the AP deployment, with a different VLAN for each AP that is deployed

Answer

the number of devices, with a different VLAN for each 250 devices

Question 6

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?

Accepted Answer

two 40 GbE links on each of the MCs

Answer

two 10 GbE links on each of the MC

Answer

three 10 GbE links on each of the MCs

Answer

four 10 GbE links on each of the MCs
