Question 1

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?

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

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

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

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

Answer : D

Question 2

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?

Aa signal of -65 dBm in the 2.4 GHz band

Ba signal of -75 dBm in the 5 GHz band

Ca signal of -65 dBm in the 5 GHz band

Da signal of -75 dBm in the 2.4 GHz band

Answer : C

Question 3

An architect needs to deliver an upgrade to an 802.11ac-based solution for a customer. The customer requires

an active site survey for the new deployment. Which deliverable should the architect provide to the customer?

Aa heat map with proposed AP locations and actual tested coverage

Ba heat map with existing AP locations and actual tested coverage

Ca heat map with sources of RF interface, both 802.11 and non-802.11

Dthe heat map with proposed AP locations and predictive coverage

Answer : C

Question 4

Refer to the exhibit.

An architect determines that 80 Gbps bandwidth is required for the link aggregation between the Building

1aggregation layer and Building 2. Which transceivers should the architect recommend for each pair of

switches?

Atwo QSPF+ BiDi

Btwo QSPF+ MPO

Ceight SPF+ LR

Deight SFP+ SR

Answer : B

Question 5

If a Remote AP (RAP) is attempting to contact a controller that is behind a NAT device what protocol must be allowed through the NAT/Firewall?

APAPI

BNATT

CIPSec

DSSH

EGRE

Answer : B

Question 6

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?

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

BEnsure that DHCP is enabled on only the switch Default VLAN.

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

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

Answer : C

Question 7

A customer requires a wireless upgrade. The architect proposes:

Aruba AP-325s

Mobility Controller (MC) 7210s

Virtual Mobility Masters (MMs)

ClearPass

AirWave

The customer is interested in wired authentication, as well as wireless authentication, but does not have the

budget to upgrade the wired network. The wired network does not currently support 802.1X or RADIUS.

Which feature of the Aruba solution should the architect explain to justify the proposed solution?

AThe customer can direct all wired traffic through the MCs, which will then apply security to that traffic.

BThe customer can direct all wired traffic through the MMs, which will impose basic security checks.

CClearPass OnConnect can enable wired authentication on these switches through the use of SNMP.

DAirWave can manage these switches and shut down their ports if an unknown user or device connects.
