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:

To route at the core and extend some of the same VLANs in different buildings, the architect should recommend creating a backplane stack at the aggregation layer and a VSF fabric at the core. A backplane stack is a logical switch that combines multiple physical switches into a single unit, using dedicated stacking cables or ports. A VSF fabric is a virtual switch that combines multiple physical switches into a single unit, using standard Ethernet links. Both technologies provide high availability, scalability, and simplified management for the network12.

By creating a backplane stack at the aggregation layer, the architect can reduce the number of routing interfaces and routing protocols needed at the core layer, as well as simplify the configuration and maintenance of the aggregation switches. By creating a VSF fabric at the core layer, the architect can enable Layer 2 connectivity across different buildings, as well as provide redundancy and load balancing for the core switches. The VSF fabric can use Multi-Chassis Link Aggregation (MC-LAG) to extend the same VLANs to different aggregation stacks, without creating loops or blocking ports3.

The other options are not suitable for the customer’s requirements. Implementing broadcast filtering on switch-to-switch links across all of the buildings would not enable Layer 2 connectivity across different buildings, as it would prevent the propagation of Layer 2 control traffic, such as Spanning Tree Protocol (STP) and VLAN Trunking Protocol (VTP). Combining all switches in the aggregation layer and core into a single backplane stack would not be feasible, as it would require compatible switches and sufficient stacking ports or cables, as well as create a single point of failure for the entire network. Using VRRP on the core and aggregation switches, with the aggregation switches acting as standby, would not eliminate the routing at the aggregation layer, as it would still require the aggregation switches to participate in the routing process and maintain routing tables.

An active site survey is a method of measuring and validating the wireless coverage, capacity, and performance of a network in a specific environment. It involves deploying temporary APs in the proposed locations, collecting data using a survey tool, and analyzing the results to optimize the network design. A heat map is a graphical representation of the wireless signal strength, interference, noise, or other metrics in different areas of the site. A heat map with proposed AP locations and actual tested coverage is a deliverable that shows the customer the expected performance of the new 802.11ac-based solution, and allows the architect to fine-tune the AP placement, channel selection, transmit power, and antenna orientation. This deliverable also helps the customer to verify that the network meets their requirements for coverage, capacity, and quality of service. References:
