質問 46
Scenario:
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 AirWave
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. 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.
- B. specify the VLANs in network policies on AirWare, and ensure that both the switches and MCs are managed by AirWare
- C. use the MCs to assign wired users to their VLANs, and extend the VLANs to a Layer 3 switch connected to the MC
- D. 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.
正解: D
質問 47
An architect plans to purpose two Aruba Mobility Controllers (MCs) in a cluster. The customer has a large
building that needs to support about 10,000 devices. The architect plans to associate the Employees WLAN
with VLAN ID 10.
What is one Aruba best practice for this design?
- A. Ensure that optimization and suppression of unnecessary multicast is enabled.
- B. Ensure that VLAN 10 is extended to the edge and Aruba APs are deployed on it.
- C. Ensure that each user role on the MCs is associated with a different VLAN ID.
- D. Ensure that the RADIUS server assigns users to different VLANs dynamically.
正解: D
質問 48
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. Implement broadcast filtering on switch-to-switch links across all of the buildings.
- B. Combine all switches in the aggregation layer and core into a single backplane stack.
- C. Use VRRP on the core and aggregation switches, with the aggregation switches acting as standby.
- D. Create a backplane stack at the aggregation layer and a VSF fabric at the core.
正解: B
質問 49
