Which guidelines should an architect use to determine how many AirWave servers to recommend?
An architect should recommend one AirWave server to monitor and manage up to about 4,000 infrastructure devices. This is because each AirWave server is designed to support a high number of network devices, including access points, switches, and controllers, facilitating comprehensive infrastructure management within this capacity.
An architect plant to purpose an Aruba wireless solution with several Mobility Controllers (MCs) and a Mobility Master (MM) architecture. Wireless users run Skype for Business, a Unified Communications (UC) solution. The architect plans to use the Aruba SDN capabilities to integrate with the UC solution.
What helps to support high availability specifically for the SDN services?
To support high availability specifically for the SDN services in an Aruba wireless solution, the best approach is a cluster deployment for Mobility Controllers (MCs). Clustering allows multiple controllers to work together in a coordinated manner, providing redundancy and load balancing. This ensures that the SDN services remain available even if one controller fails, thus maintaining high availability for critical services such as Unified Communications (UC) solutions like Skype for Business. A cluster deployment helps distribute the load efficiently and provides failover capabilities, which is essential for uninterrupted SDN services.
Refer to the exhibits.
Exhibit 1 shows the logical plan, and Exhibit 2 shows the BOM created with IRIS. An architect plans to propose two 5406Rzl switches as a VSF fabric for a campus network core. Which issue with the plan should the architect correct?
Exhibit 1 -
Exhibit 2 -
The architect should change the v2 modules to v3 modules. The 5400R zl2 switches require v3 modules for proper operation when used in a VSF (Virtual Switching Framework) fabric. When VSF is enabled, the switch enforces v3 only mode, which means that any v2 modules currently installed will be disabled. Therefore, the proposed setup must include v3 modules instead of v2 to ensure all components are compatible and operational.
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?
The architect must account for a total of up to 60 Gbps of wireless traffic (25 Gbps upstream and 35 Gbps downstream). The customer requires that the system continues to forward traffic if up to one link fails, though performance may be reduced. Each of the two Aruba 7240 Mobility Controllers must be able to handle the traffic even if one 10 GbE link fails. With four 10 GbE links, each controller has 40 Gbps capacity. This ensures that even if one link fails, the remaining three links will provide 30 Gbps capacity, which is still sufficient to handle the reduced performance requirement under failover conditions. Therefore, the minimal configuration to meet the requirements is four 10 GbE links on each of the MCs.
An architect needs to help a customer design a management and monitoring solution for an Aruba network in an airport. The solution consists of an Aruba Mobility
Master (MM), Aruba 7210 MCs, Aruba AP-335s, and Aruba 5496R switches. The architect plans to recommend Aruba AirWare.
The airport has a high-client device turnover and many highly mobile devices. Which changes should the architect make to the recommended solution based on this characteristic?
For a high-client device turnover and a large number of highly mobile devices, the recommendation should center on the adequate provisioning of resources to handle the increased demand and processing load. This scenario, with a high number of clients and frequent roaming, particularly stresses the hardware's processing capabilities. Therefore, additional hardware resources beyond those recommended for a typical AirWave platform are necessary to ensure optimal performance and reliability, making it the appropriate change to recommend.
