NEW QUESTION 2
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.

Answer: C

NEW QUESTION 3
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?

• 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.

Answer: C

NEW QUESTION 4
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?

• 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.

Answer: C

Answer: B

NEW QUESTION 10
An architect needs to plan a very high density (VHD) wireless network at a large events venue, at which thousands of attendees are expected.

Answer: B

NEW QUESTION 16
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.
Which solution should the architect recommend on the 2930M switches to authenticate and control wired employee devices?

• A. MAC-Auth on edge ports and no tunneled node
• B. 802.1X on edge ports and per-user tunneled node
• C. 802.1X on edge ports and no tunneled node
• D. Mac-Auth on edge ports and per-user tunneled node

Answer: A
