 Aruba Instant APs are a simple, easy to deploy, and cost-effective solution for small office buildings that need wireless access. Aruba Instant APs can form a self-organizing and self-healing mesh network that supports basic rogue AP detection and provides a stateful firewall with role-based policies. Aruba Instant APs do not require a separate controller or license, and can be managed from the cloud or a mobile app. Aruba remote APs are designed for branch or home offices that need to connect to a central controller over a WAN link. Aruba campus APs and a Virtual Mobility Controller are suitable for larger or more complex deployments that need more scalability and flexibility. Aruba campus APs and an Aruba 7005 Mobility Controller are also more expensive and require additional hardware and licensing. References: Aruba Instant Access Points), Aruba Validated Design: Campus Wireless LAN)

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. References:

According to the Designing Aruba Solutions course, dedicated Air Monitors (AMs) are APs that are configured to scan all channels for wireless threats and perform wireless intrusion prevention system (WIPS) functions. One of the advantages of using dedicated AMs over APs that are doing WIPS in AP mode (hybrid) is that AMs can implement wireless containment on any channel on which they detect a threat without affecting the service of legitimate clients. Wireless containment is a technique that prevents rogue APs or clients from communicating with the network by sending deauthentication or disassociation frames to them. However, if an AP that is serving clients performs wireless containment on a different channel, it will have to switch channels frequently, which will degrade the performance and user experience of the clients. Therefore, dedicated AMs are recommended for customers who need effective and efficient wireless containment without compromising client service.

802.1X authentication without tunnelled node is a form of port-based network access control that uses the Extensible Authentication Protocol (EAP) to authenticate users and devices on a wired network. This form of authentication provides several benefits, such as:

It enables user access control and ensures only authorized users connect. This prevents unauthorized access to the network and its resources, and enhances security and compliance.

It allows dynamic assignment of VLANs and roles based on user identity and device type. This simplifies network management and improves user experience.

It supports multiple authentication methods, such as certificates, passwords, tokens, or biometrics. This provides flexibility and choice for users and administrators.

It integrates with Aruba ClearPass Policy Manager (CPPM) for centralized policy enforcement and visibility. This enables granular control and monitoring of wired user traffic and devices. References:

The maximum bandwidth possible between the aggregation and core layers using 8 strands of OM4 Multi-Mode fiber can be up to 200 Gbps1. This is because each strand of OM4 fiber can support up to 25 Gbps of bandwidth, and with 8 strands, the total bandwidth can reach up to 200 Gbps1. However, the actual bandwidth can be influenced by various factors such as the quality of the fiber, the type of transceivers used, and the distance between the aggregation and core layers1.

Aruba 5400R zl2 Switch Series Data Sheet

Aruba 5400R zl2 Switch Series Installation and Getting Started Guide

ArubaOS-Switch and ArubaOS-CX Transceiver Guide

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.

Air Monitors (AMs) are Aruba access points (APs) that are configured to operate in a dedicated mode for scanning the RF spectrum and detecting rogue APs, clients, and intrusion attacks. AMs do not serve any wireless clients and can scan all channels in both 2.4 GHz and 5 GHz bands. AMs provide better visibility and coverage of the RF environment than APs that serve clients, as they can scan more frequently and thoroughly. However, AMs also consume more power and network resources than APs, and require additional hardware and licensing costs. Therefore, the optimal number of AMs per floor depends on several factors, such as the size and shape of the floor, the density and distribution of APs and clients, the security and compliance requirements, and the budget and availability of the organization.

According to the Aruba Wireless Intrusion Protection (WIP) Technology Guide1, a general rule of thumb is to deploy one AM for every four to six APs. This ratio can provide adequate coverage and detection for most environments, while balancing the trade-offs between performance and cost. However, this ratio is not fixed and can vary depending on the specific needs and characteristics of each deployment. For example, if the floor has a high density of APs and clients, or a high risk of rogue or malicious activity, more AMs may be needed to provide better security and visibility. Conversely, if the floor has a low density of APs and clients, or a low risk of rogue or malicious activity, fewer AMs may be sufficient to provide adequate security and visibility.

In this case, the floor has 20 APs, which implies a moderate to high density of APs and clients. Assuming that the floor has a rectangular shape and a uniform distribution of APs and clients, a reasonable estimate of the number of AMs per floor would be about 3 to 5, based on the general rule of thumb. This would provide enough coverage and detection for most scenarios, while minimizing the additional costs and resources. However, this estimate may need to be adjusted if the floor has a different shape or a non-uniform distribution of APs and clients, or if the organization has specific security and compliance requirements that demand more or less AMs per floor. References:

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.
