HP HPE6-A47 Dumps Questions Answers

it meets the customer’s requirements for wired network upgrade. By combining the switches in each Building 2 closet as a Virtual Switching Framework (VSF) fabric, the architect can reduce the number of logical devices within the network, simplifying management and reducing complexity, aligning with the goal of flattening architecture. Establishing two 10 GbE connections to the core per fabric ensures redundancy and resilience, maintaining connectivity even if one link fails, without necessitating additional cabling. This also provides sufficient bandwidth and scalability for the network traffic.

The other options are incorrect because:

• A. Using two additional 2930F switches to act as an aggregation layer for Building 2 adds another layer of devices and complexity to the network, contradicting the goal of flattening architecture. It also requires additional cabling and ports to connect the switches to the core and the access layer.
• B. Connecting each Building 2 switch directly to the core on a single fiber strand through the use of SFP±SR transceivers does not provide redundancy and resilience, as one link failure would disconnect the switch from the core. It also limits the bandwidth and scalability of the network, as each switch would have only one 10 GbE connection to the core.
• D. Extending additional fiber between the buildings so that each Building 2 switch can have a direct 10 GbE connection to the core requires recabling, which the customer wants to avoid. It also increases the cost and complexity of the network, as more fiber strands and ports would be needed.

A customer who has an Instant AP deployment and needs to provide client-to-site VPN access for remote users would benefit from adding a controller to the deployment. A controller can act as a VPN concentrator that terminates the VPN tunnels from the remote clients and provides secure access to the corporate network. The controller can also apply firewall policies and role-based access control to the VPN traffic. An Instant AP deployment alone cannot provide this functionality, as it only supports site-to-site VPN between Instant AP clusters12. The other options do not require a controller, as they can be achieved with an Instant AP deployment. An Instant AP deployment can apply role-based firewall policies using the built-in stateful firewall on each Instant AP3. An Instant AP deployment can also provide a captive portal for guests using the internal orexternal web server options4. An Instant AP deployment can be managed by a cloud-based solution such as Aruba Central, which does not require a controller5. References:

The Virtual Switching Framework (VSF) is a technology that allows two or more Aruba switches to operate as a single logical device, providing high availability, simplified management, and increased performance. VSF is supported on Aruba 5400R zl2 switches, which are modular switches that can accommodate different types of line cards and power supplies1.

The VSF fabric requires two types of connections between the member switches: VSF links and VSF ports. VSF links are the physical connections that carry the VSF control and data traffic, while VSF ports are the logical interfaces that bundle the VSF links into a single logical link. VSF links can be either 10 GbE or 40 GbE, and VSF ports can be either 10 GbE or 40 GbE1.

To create a VSF fabric with two 5406R zl2 switches, the architect needs to ensure that the switches have the compatible modules, transceivers, and cables for the VSF links and ports. According to the ArubaOS-Switch Management and Configuration Guide1, the following requirements apply for the VSF fabric:

• The switches must have the same chassis model, the same number and type of modules, and the same firmware version.
• The switches must have at least one v3 module in slot A or B. The v3 modules are the ones with the letter “M” in the part number, such as J9990A, J9991A, and J9992A. The v2 modules are the ones with the letter “A” in the part number, such as J9534A, J9535A, and J9536A.
• The switches must have the same type of transceivers and cables for the VSF links. The supported transceivers are the Aruba 10G SFP+ LC SR, the Aruba 10G SFP+ LC LR, the Aruba 40G QSFP+ LC SR4, and the Aruba 40G QSFP+ MPO SR4. The supported cables are the Aruba 10G SFP+ to SFP+ 1m DAC Cable, the Aruba 10G SFP+ to SFP+ 3m DAC Cable, the Aruba 40G QSFP+ to QSFP+ 1m DAC Cable, and the Aruba 40G QSFP+ to QSFP+ 3m DAC Cable.

Based on the exhibit, the architect has planned to use the Aruba 40G QSFP+ to QSFP+ 1m DAC Cable (JH234A) for the VSF links, which is a supported option. However, the architect has also selected the Aruba 24p 10GBASE-T v2 zl Module (J9536A) and the Aruba 20p 10GbE SFP+ v2 zl Module (J9535A) for the switches, which are not compatible with the VSF fabric. The architect should change these v2 modules to v3 modules, such as the Aruba 24p 10GBASE-T v3 zl2 Module (J9996A) and the Aruba 20p 10GbE SFP+ v3 zl2 Module (J9990A), to meet the VSF requirements.

The other options are not issues with the plan. Adding two QSPF+ MP0 SR4 transceivers (A) is not necessary, as the DAC cable already provides the 40 GbE connection for the VSF links. Adding stacking modules and cables © is not required, as the VSF fabric does not use the traditional stacking technology. Changing the power supply type (D) is not relevant, as the VSF fabric does not impose any restrictions on the power supply type.
