A financial institution has an Aruba wireless system. Each floor is 19 meters by 23 meters (200 feet by 250 feet) and has 20 APs. The organization now requires dedicated Air Monitors (AMs). About how many AMs should the architect recommend per floor?
The number of required Air Monitors (AMs) in a network is generally based on the ratio to Access Points (APs). In an environment with 20 APs per floor, normal density would suggest one AM for every four APs, which leads to approximately 5 AMs. In a high-density environment, fewer AMs are needed per AP, around one AM for every seven to ten APs, resulting in about 2 to 3 AMs. Balancing these considerations, the recommended range is about 3 to 5 AMs per floor to ensure adequate coverage and monitoring. This range covers both normal and high-density scenarios effectively.
A customer needs a solution to terminate VPN tunnels for Aruba RAPs. The customer has a single site and a single public IP address for this purpose. Network address translation (NAT) will forward the IPsec traffic to the correct device to terminate the VPN tunnel. The customer also requires N+1 redundancy for the solution. Which solution meets the customer requirements?
The solution that meets the customer requirements of terminating VPN tunnels for Aruba RAPs with a single public IP address and N+1 redundancy is to use two Aruba MCs on the same subnet that use VRRP without clustering. This setup avoids the need for each controller in a cluster to have a unique public IP, which the customer does not have. VRRP provides the necessary redundancy while allowing the IPsec traffic to be forwarded to the correct device.
An architect needs to plan the RF coverage. Which application has the greatest potential impact on RF design?
Voice applications have the greatest potential impact on RF design because they typically require consistent, low-latency connectivity to maintain call quality. They are more sensitive to issues like interference, coverage gaps, and poor signal strength compared to other applications such as print, email, or secure web browsing.
For which scenario should an architect recommend Aruba Central Managed Portal (MSP)?
Aruba Central Managed Portal (MSP) is specifically designed for service providers who need to manage multiple customer networks. It allows Managed Service Providers to efficiently monitor and operate various customer environments from a single interface, providing centralized management and scalability.
An architect proposes an Aruba solution with a hardware Mobility Master (MM) to a customer. The customer has a disaster recovery site which is connected to the main site at Layer 3. The customer requires the MM to remain available in case of a total site failure.
Which plan meets the customer requirements?
To ensure that the Mobility Master (MM) remains available in case of a total site failure at the primary location, deploying a hardware MM to the disaster recovery site and setting its IP address as the standby master for the Mobility Controllers (MCs) meets the requirement. This approach ensures that the MM can take over management duties seamlessly in the event of a failure at the primary site. VRRP is not suitable for Layer 3 redundancy across different sites, and clustering does not provide the necessary Layer 3 MM redundancy.
