Question 8

Scenario: An architect proposes these products for a customer who wants a wireless and wired upgrade: Aruba 2930M switches at the access layer Aruba 5406R switches at the core Aruba AP-325s Aruba 7205 Mobility Controllers (MCs), deployed in a cluster Aruba Mobility Master (MM) Aruba ClearPass Cx000V Aruba AirWave The architect also needs to propose a security plan for the solution. The customer has 900 employees and up to 30 guests a day. The customer wants to protect the internal perimeter of the network with authentication and simple access controls. The customer is most concerned about wireless security, but also wants to ensure that only trusted users connect on the wire. However, the customer also wants all wired traffic to be forwarded locally on access layer switches. The customer already has a third-party firewall that protects the data center. The customer wants to use certificates to authenticate user devices, but is concerned about the complexity of deploying the solution. The architect should recommend a way to simplify. For the most part users connect company-issued laptops to the network. However, users can bring their own devices and connect them to the network. The customer does not know how many devices each user will connect, but expects about two or three per-user. DHCP logs indicate that the network supports a maximum of 2800 devices. Refer to the provided scenario. Which ClearPass licenses should the architect include in the proposal?

Accepted Answer

A)  1,000 Access licenses and 1000 Onboard licenses 
B)  1,000 Access licenses and 3,000 (3x1000) Onboard licenses 
C)  3,000 Access licenses (3x1000) and 1000 Onboard licenses 
D)  3,000 Access licenses and 3,000 (3x1000) Onboard licenses

Question 9

Refer to the exhibit.  An architect selects 5406R switches for the aggregation layer. What is the maximum bandwidth possible between the aggregation and core layers using 8 strands of OM4 MM fiber at the distances indicated in the diagram?

Accepted Answer

Accepted Answer

A)  Use EAP-TLS instead of PEAP-MSCHAPv2. 
B)  Use TKIP encryption instead of AES. 
C)  Add WPA2-PSK as an alternative to WPA2-Enterprise. 
D)  Add Tunneled TLS (TTLS) as an alternative to PEAP-MSCHAPv2.

Question 11

An architect plans 128 APs to support 12,800 devices in a very high density (VHD) design. The customer requires high availability, so the architect plans to recommend a pair of controllers. What is one reason to recommend 7210 controllers rather than 7205 controllers for this deployment?

Accepted Answer

A)  the need for high speed 10 GbE ports 
B)  the need for clustering 
C)  the number of devices required 
D)  the number of APs required

Question 12

A financial institution has an Aruba wireless system. Each floor is 19 meters by 23 meters (200 feet by 250 feet) and has 20 APs. The organization now requires dedicated Air Monitors (AMs). About how many AMs should the architect recommend per floor?

Accepted Answer

A)  about 1 or 2 per floor 
B)  about 3 to 5 per floor 
C)  about 10 to 12 per floor 
D)  about 16 to 20 per floor

Question 13

Refer to the exhibit.  The exhibit shows the current plan for a wired network upgrade. As much as possible, the customer wants to flatten the architecture and avoid recabling. However, each Building 2 switch must also maintain connectivity to the core if one link fails. What should the architect propose to meet the customer requirements?

Accepted Answer

A)  Use two additional 2930F switches to act as an aggregation layer for Building 2; connect them to the core on 40 GbE connections. 
B)  Connect each Building 2 switch directly to the core on a single fiber strand through the use of SFP+-SR transceivers. 
C)  Combine the switches in each Building 2 closet as a VSF fabric; establish two 10 GbE connections to the core per fabric. 
D)  Extend additional fiber between the buildings so that each Building 2 switch can have a direct 10 GbE connection to the core.

Question 14

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

A)  the requirement to apply role-based firewall policies 
B)  the requirement for a captive portal for guests 
C)  the requirement to provide client-to-site VPN acces for remote users 
D)  the requirement for a cloud-based management solution

Question 15

A customer needs a networking solution that supports their Microsoft Skype for Business Unified Communications (UC) solution. The architect discovers that user wireless devices are Wi-Fi Multimedia (WMM) capable. Windows policies assign voice traffic DSCP 46 and video traffic DSCP 34. Which potential issue should the architect explain to the customer about the default QoS settings?

Accepted Answer

A)  The DSCP values place both voice and video traffic in the video WMM queue, so voice does not receive the prioritization that is should. 
B)  The Aruba APs and controllers use different prioritization mechanisms from WMM, so they will not accept high priority traffic from the wireless devices. 
C)  DSCP is incompatible with WMM. The Aruba APs and controllers instead use 802.1p to mark traffic to and from wireless devices. 
D)  The DSCP for wireless client traffic is concealed within the GRE packet on the path from the AP to the controller, and does not take effect.

Question 16

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?

Accepted Answer

A)  The customer can direct all wired traffic through the MCs, which will then apply security to that traffic. 
B)  The customer can direct all wired traffic through the MMs, which will impose basic security checks. 
C)  ClearPass OnConnect can enable wired authentication on these switches through the use of SNMP. 
D)  AirWave can manage these switches and shut down their ports if an unknown user or device connects.

Question 17

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

Accepted Answer

A)  insufficient fiber cabling, especially between buildings

C)  simplification of spanning tree protocol at the access layer 
D)  need to extend VLANs across wider areas

Question 18

An architect needs to plan a wireless deployment. The architect conducts a physical walkthrough, but still needs more information. Which significant RF obstacle can be difficult to see visually and might require access to blueprints?

Accepted Answer

A)  fiberglass 
B)  metal firewall 
C)  ceiling tiles 
D)  drywall

Question 19

A customer needs an 802.11ac upgrade for an office with cubicles. The customer states that, because they planned locations for the existing 802.11n 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

A)  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. 
B)  The new 802.11ac deployment should have a capacity-based design for the best performance, but the existing deployment sounds like a coverage-based design. 
C)  802.11ac AP radios tend to be more sensitive to 2.4 GHz interference than 802.11n APs, so the architect needs to search for all potential sources of such interference. 
D)  802.11ac APs can support a higher density of clients, so they can be deployed farther apart than the APs in most existing 802.11n deployments.

Question 20
