The solution that the architect should recommend on the 2930M switches to authenticate and control wired employee devices is 802.1X on edge ports and no tunneled node. This solution would provide strong authentication and authorization for the wired devices using certificates, which can be issued and managed by ClearPass. The 802.1X protocol would allow the switches to communicate with ClearPass and enforce user roles and policies based on the device identity and context. The no tunneled node option would allow the wired traffic to be forwarded locally on the access layer switches, as the customer prefers, without tunneling it to the MCs. This option would also reduce the bandwidth consumption and latency on the network core.

The other solutions are not optimal for the customer requirements because they either provide weak authentication or require tunneling the wired traffic to the MCs. MAC-Authon edge ports and no tunneled node would provide weak authentication based on the MAC address of the device, which can be easily spoofed or bypassed. MAC-Auth on edge ports and per-user tunneled node would also provide weak authentication and require tunneling the wired traffic to the MCs, which the customer does not want. 802.1X on edge ports and per-user tunneled node would provide strong authentication but also require tunneling the wired traffic to the MCs, which the customer does not want. References:

This is a routed link, meaning you should only have one VLAN assigned to the link. Obvious since VLANs are terminated at a layer 3 boundary, but also right out of the curriculum.

The Aruba 7210 Mobility Controller is designed to support up to 512 APs and 16,384 simultaneous users. In contrast, the 7205 Mobility Controller supports up to 256 APs and 8,192 simultaneous users. Therefore, for a very high density (VHD) design with 128 APs supporting 12,800 devices, the 7210 controllers would be a better fit due to their higher capacity for APs and simultaneous users.

The Aruba MC 7010 and 7024 are both designed for small to mid-sized campuses and branches, but they have some differences in their features and specifications. One of the main differences is the number and type of ports they offer. The MC 7010 has 16 10/100/1000BASE-T ports, while the MC 7024 has 8 10/100/1000BASE-T ports and 8 1000BASE-X SFP ports1. This means that the MC 7024 can support more APs that require fiber connections, such as the AP-387 or the AP-5352. The MC 7024 also supports 10G ports, which can provide higher bandwidth and performance for the network backbone3.

Therefore, if the customer needs to connect 20 APs directly to the MC, and some of them require fiber or 10G connections, the MC 7024 is a better choice than the MC 7010. The other options (A, B, and C) are not relevant for choosing between the MC 7010 and 7024, as both models can support up to 64 APs and 4096 users or devices, and both models can provide PoE+ on 12 ports1.

A cluster is a group of MCs that work together to provide high availability, seamless roaming, and load balancing for wireless clients and APs. A cluster requires all MCs to be on the same VLAN and subnet, and to have the same software version and configuration. A cluster supports stateful failover for user connections, which means that if an MC fails, the user sessions are preserved and transferred to another MC in the cluster without any disruption. A cluster also supports hitless failover for APs, which means that if an MC fails, the APs that were connected to it automatically join another MC in the cluster without rebooting. A cluster is the recommended design for high availability for wireless services12. References:

 The correct answer is option C, conversion of the existing Instant APs to campus APs (CAPs). This is because the existing Instant APs can be converted to CAPs by changing their operating mode and pointing them to the MC. This way, the customer can leverage the existing APs and avoid purchasing new ones. The MC can then provide centralized management, configuration, and control for the APs.

Option A is incorrect because the purchase of Universal APs is not necessary. Universal APs are APs that can operate in either Instant or CAP mode without requiring a conversion. However, the existing APs can be converted to CAPs without buying new ones.

Option B is incorrect because Aruba ClearPass is not required to onboard the APs as CAPs in the new MC-based deployment. Aruba ClearPass is a network access control (NAC) solution that provides authentication, authorization, and accounting (AAA) services for wired and wireless devices. It is not involved in the conversion of Instant APs to CAPs.

Option D is incorrect because a Virtual Mobility Controller (VMC) is not a valid option to control Instant APs. A VMC is a software-based MC that runs on a hypervisor. It can control CAPs, but not Instant APs. Instant APs can only be controlled by another Instant AP acting as a Virtual Controller (VC).

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.

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.

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:

In a high-client device turnover environment like an airport, the network management and monitoring solution needs to handle a large number of devices connecting and disconnecting frequently. This can put a significant load on the system. Therefore, it would be beneficial to recommend additional hardware resources beyond those typically recommended for the AirWare platform. This would ensure that the system can handle the high turnover and provide reliable service1.
