• 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.

NEW QUESTION 8
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?

• A. a signal of -65 dBm in the 2.4 GHz band
• B. a signal of -75 dBm in the 5 GHz band
• C. a signal of -65 dBm in the 5 GHz band
• D. a signal of -75 dBm in the 2.4 GHz band

NEW QUESTION 9
An architect simulates VoIP calls and tests the throughput as 67 Kbps, packet loss as 0.3 percent, maximum latency as 100 ms, and maximum jitter as 100 ms. Which issue typically causes a poor experience for users?

NEW QUESTION 10
An architect proposes an Aruba wireless solution for a customer that uses Microsoft Skype for Business. What should be set up on the MCs, or MM, to ensure that wireless voice traffic is properly prioritized?

NEW QUESTION 11
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?

• 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 switche
• D. Extend the VLANs to the core.
• E. 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.

Answer: C

NEW QUESTION 12
Refer to the exhibit.

• D. VRRP

Answer: C

• C. the need to deploy controllers in a cluster
• D. whether the MC needs to support advanced 8.x features

Answer: A

NEW QUESTION 14
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?

• 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 WM
• D. The Aruba APs and controllers instead use 802.1p to mark traffic to and from wireless devices.
• E. 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.

Answer: A

NEW QUESTION 15
