NEW QUESTION 7
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 8
What is one reason to recommend dedicated Air Monitors (AMs) for a customer, as opposed to APs that are doing WIPS in AP mode (hybrid)?

• A. AMs can operate in a hybrid operation mode in which they can support clients, scan for threats, and contain detected threats.
• B. AMs can implement wireless containment on any channel on which they detect a threat without negative impact on clients.
• C. AMs can detect both 802.11 and non-802.11 sources of interference to the wireless network, while APs cannot.
• D. AMs can maintain client and AP blacklists on their own without the need to communicate with a Mobility Controller (MC).

Answer: B

NEW QUESTION 9
What is a key criteria that an architect should use to choose between an Aruba 7000 Series or 7200 Series Mobility Controller (MC)?

• A. the number of wireless devices that the MC needs to support
• B. whether the MC needs to terminate VPN tunnels
• C. the need to deploy controllers in a cluster
• D. whether the MC needs to support advanced 8.x features

Answer: A

NEW QUESTION 10
Refer to the exhibit.

A customer wants to replace the core and aggregation layer of an existing network. Currently the network routes between the aggregation layer and core, and uses the technologies shown in the exhibit.
The customer now wants to route at the core, instead of the aggregation layer, and extend some of the same VLANs in different buildings. However, the customer cannot eliminate the aggregation layer at this point. What should the architect recommend?

• A. Create a backplane stack at the aggregation layer and a VSF fabric at the core.
• B. Implement broadcast filtering on switch-to-switch links across all of the buildings.
• C. Combine all switches in the aggregation layer and core into a single backplane stack.
