Question No : 1
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 ClearPass licenses should the architect include in the proposal?

• 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 No : 2
Refer to the exhibit.



The customer needs to expand its wired and wireless network to a new building, Building 2, which is near the existing building, Building 1. The exhibit shows the logical plan that the architect has created so far. The aggregation layer switches in the new building should provide the default gateway services for the VLANs in the new building and route traffic to the core. The existing Aruba Mobility Controllers (MCs) will control the new APs.
What should be the VLAN assignment for Link 1, indicated in the exhibit?

• A.an unused VLAN such as 200
• B.VLANs 21, 22, and 23 only
• C.VLANs 11, 12, 13, 21, 22, and 23
• D.the default VLAN and VLAN 14

Question No : 9
The customer has an office environment with users who have laptops that can connect with wired or wireless. Users also bring one or two of their own devices. An architect creates a proposal with Aruba AP­325s, 7210 Mobility Controllers (MCs), a Mobility Master (MM), and Aruba 2930M switches at the access layer to support the laptops and APs.
The architect plans to recommend 802.1X authentication without tunneled node on Aruba 2930M switch ports that connect to laptops.
What is one advantage of this form of authentication?

• A.ensures that Aruba firewall policies apply to wired user traffic.
• B.prevents users from connection attempts with more than three devices
• C.enables user access control and ensures only authorized users connect.
• D.provides a second layer of protection for wireless users at the internal perimeter
