Designing Aruba Solutions Questions and Answers

Question 1

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?

Options:

A.

The DSCP values place both voice and video traffic in the video VMM queue, so voice does not receive the prioritization that is should.

B.

The Aruba APs and controllers use different prioritization mechanism 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 2

An architect proposes an Aruba solution with a hardware Mobility Master (MM) to a customer. The customer has a disaster recovery site which is connected to the main site at Layer 3. The customer requires the MM to remain available in case of a total site failure.

Which plan meets the customer requirements?

Options:

A.

Deploy a hardware MM to the disaster recovery site and set up VRRP between them.

B.

Deploy a hardware MM to the disaster recovery site and set its IP address as the standby master for MCs.

C.

Deploy the virtual MM (VMM) to the disaster recovery site and set the VMM IP address to the same address as the hardware MM.

D.

Deploy the virtual MM (VMM) to the disaster recovery site and configure clustering on the hardware and software appliances.

Question 3

Read this scenario thoroughly, and then answer each question that displays on the right side of the screen.

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 AirWare

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. Based on the plan for wired authentication, what is a correct plan for wired user VLANs?

Options:

A.

use the MCs to assign wired users to their VLANs, and extend the VLANs to a Layer 3 switch connected to the MC

B.

specify the VLANs in network policies on AirWare, and ensure that both the switches and MCs are managed by AirWare

C.

assign wired users to different VLANs from wireless users, based on port or role assignments on access layer switches. Extend the VLANs to the core.

D.

configure the same roles on switches and MCs to place wired and wireless users in the same VLANs. Extend VLANs from access layer switches to the core.

Question 4

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.
