- A. Create a backplane stack at the aggregation layer and a VSF fabric at the core.
- B. Use VRRP on the core and aggregation switches, with the aggregation switches acting as standby.
- C. Combine all switches in the aggregation layer and core into a single backplane stack.
- D. Implement broadcast filtering on switch-to-switch links across all of the buildings.
Answer: C

NEW QUESTION # 30
An architect needs to plan the bandwidth for two Aruba 7240 Mobility Controllers (MCs) which will connect to the network core. The customer indicates that four 10 GbE links between the network core and the data center will be adequate. The customer expects almost all traffic in the network will be wireless. The customer expects up to 25 Gbps upstream traffic from wireless clients and up to 35 Gbps downstream to wireless clients.
The customer requires the MCs to be able to continue to forward traffic if up to one link fails, but lower performance during the failover situation is permissible.
What are the minimal links to meet these requirements?
- A. two 10 GbE links on each of the MC
- B. two 40 GbE links in each of the MCs
- C. four 10 GbE links on each of the MCs.
- D. three 10 GbE links on each of the MCs
Answer: B
NEW QUESTION # 31
What is a key criteria that an architect should use to choose between an Aruba 7000 Series or 7200 Series Mobility Controller (MC)?
- A. whether the MC needs to support advanced 8.x features
- B. whether the MC needs to terminate VPN tunnels
- C. the need to deploy controllers in a cluster
- D. the number of wireless devices that the MC needs to support
Answer: A
Explanation:
whether the MC needs to support advanced 8.x features. This is because the Aruba 7000 Series MCs are based on the older hardware platform and can only run up to ArubaOS 6.5.x, while the Aruba 7200 Series MCs are based on the newer hardware platform and can run ArubaOS 8.x and above. ArubaOS 8.x introduces many advanced features, such as clustering, MultiZone, AirMatch, and dynamic segmentation, that are not supported by the Aruba 7000 Series MCs. Therefore, if the architect needs to design a solution that leverages these features, the Aruba 7200 Series MCs are the better choice.
Option A is incorrect because the number of wireless devices that the MC needs to support is not a key criteria to choose between the Aruba 7000 Series or 7200 Series MCs.Both series can support a similar number of devices, depending on the model and license.
Option B is incorrect because whether the MC needs to terminate VPN tunnels is not a key criteria to choose between the Aruba 7000 Series or 7200 Series MCs. Both series can terminate VPN tunnels, such as IPSec, GRE, and RAP, depending on the model and license.
Option C is incorrect because the need to deploy controllers in a cluster is not a key criteria to choose between the Aruba 7000 Series or 7200 Series MCs. Both series can participate in a cluster, as long as they run the same ArubaOS version and have the same license.

NEW QUESTION # 32
Fast Failover has been implemented between Local 1 and Local 2 separated by Routers. During testing Local1 was disabled and all Campus APs backed up to Local 2 flawlessly. But the RAPs did not, they all failed.
What could be the cause?
- A. RAPs should be configured in their own AP-groups
- B. IPSec must be enabled on Local 2
- C. The RAP whitelist must be ported over to Local 2
- D. RAPs are not supported by Fast Failover
- E. A VPN IP Pool must be configured on Local 2

Answer: A
NEW QUESTION # 34

NEW QUESTION # 35
For which scenario should an architect recommend Aruba Central Managed Portal (MSP)?
- A. for a service provider who needs to monitor multi-vendor environments
- B. for an enterprise with many branches that needs to manage services centrally
- C. for an enterprise that needs to manage data center services together with the network
- D. for a service provider who needs to manage multiple customer networks
Answer: D
Explanation:
Aruba Central Managed Portal (MSP) is a cloud-based network management platform that enables service providers to centrally manage and monitor multiple tenant accounts from a single interface1. MSP mode is a multi-tenant operational mode that Aruba Central accounts can be converted into, provided these accounts have subscribed to the Aruba Central app2. MSP mode allows service providers to provision and manage tenant accounts, assign devices to tenant accounts, manage subscription keys and perform other functions such as configuring network profiles and viewing alerts3. MSP mode is suitable for the scenario where a service provider needs to manage multiple customer networks, as it simplifies tenant network operations using capabilities such as zero-touch setup, historical data reporting, PCI compliance monitoring, and troubleshooting2.

NEW QUESTION # 37
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?

- B. Extend additional fiber between the buildings so that each Building 2 switch can have a direct 10 GbE connection to the core.
- C. Use two additional 2930F switches to act as an aggregation layer for Building 2; connect them to the core on 40 GbE connections.
- D. Combine the switches in each Building 2 closet as a VSF fabric; establish two 10 GbE connections to the core per fabric.
Answer: D

- D. PoE+
Answer: D
NEW QUESTION # 42
Refer to the exhibit.
A customer needs to upgrade the wireless network at their campus, which has a single large building.
Employees use the wireless network to access the Internet and centralized services. The building has four floors.
These are the requirements:
30 APs on each floor
A Mobility Master (MM)-based architecture
Deployment of one Aruba 7030 Mobility Controller (MC) on each floor, with the MCs combined in a cluster for seamless client failover and roaming What should the architect explain to the customer about the proposed solution?
- A. The MC 7030 does not support enough APs for the requirements
- B. MCs should be deployed centrally on the same VLAN to better meet these goals
- C. The MC 7030 only supports clusters with up to three members
- D. MCs in a cluster must have additional AP licenses to support APs of a failed controller
Answer: A
Explanation:
The customer needs to upgrade their wireless network, which has a single large building with four floors. The customer requires 30 APs on each floor, totaling 120 APs for the whole building. The customer also wants to use a MM-based architecture, and deployone Aruba 7030 MC on each floor, with the MCs combined in a cluster for seamless client failover and roaming. However, the proposed solution does not meet the customer's requirements, because the Aruba 7030 MC does not support enough APs for the customer's needs. Each Aruba
7030 MC can only support up to 64 APs, which means that deploying one on each floor would not be enough to support all the required APs. The architect should explain this limitation to the customer, and suggest a different solution that can support more APs, such as using a higher-capacity MC model, or deploying more MCs per floor.
