HP-Aruba Certified Mobility Expert 8 Written Exam

A network architect plans to propose a virtual Mobility Master (VMM) for a new solution. The solution will support up to 4,800 wireless client devices and include: two Virtual Mobility Controllers (VMCs) in a cluster 180 APs
Which licenses should the architect propose?

A school district has instant APs (IAPs) at multiple locations. The school district wants a simpler way to manage the IAPs from a single location. However, it does not have the IT staff to handle the installation and management of a
management solution on site.
What should the architect recommend?

A customer has an existing Aruba wireless solution to provide wireless access for employees. The solution includes APs, mobility controllers (MCs) at the network core, and a Mobility Master (MM). A customer would like to set up a
separately managed guest network and have the traffic go directly to the DMZ.
What should the architect suggest as the simplest solution that meets the requirements?

In which scenario do Aruba 2930M Series switches, but not Aruba 2930F Series switches, meet the needs for an upgrade of the wired access layer?

What is one reason that an architect might choose to use pico-cell coverage rather than overhead in a stadium?

A customer has a campus that has expanded to several buildings. The buildings are between 100 and 200 feet (30 m and 61 m) apart and connected with SM fiber. The customer currently has instant APs (IAPs) clusters on several floors of several buildings. The customer has consolidated central resources in a small data center in one of the buildings. The customer would like a more centralized architecture in which all wireless traffic is tunneled to the data center and IAPs are managed centrally. What should the architect recommend?

In which of these scenarios do the customer requirements point towards tunneled node, or dynamic segmentation, on AOS-Switches?

A retailer wants to provide wireless services for guests across a section of store floor, which consists of 82 foot (25m) long aisles of cans and dry food goods. The shelves are six feet (1.8 m) high, and the ceiling height is 13 feet (4 m) high. The architect recommends overhead APs deployed at 40-50 foot (12 to 15 m) intervals every few aisles rather than in every aisle. What is one factor that justifies this recommendation?

An indoor sports stadium has 5,000seats in two rings: The stadium has a ceiling height of 72 feet (22 m). There is a catwalk around the perimeter of the stadium that is 54 feet (13 m) from the floor. There are two scoreboards at either and of the stadium. The construction of the stadium is concrete and steel. The customer has indicated a preference for overhead coverage, and the wireless network should support 3500 concurrent clients. The architect plans to install the APs on the catwalk to service sections of the floor below. Which type of antennas are recommended for the APs that provide the overhead coverage?

Case study A retailer needs a wireless and wired network upgrade, as well as an authentication and access control solution for a network that includes a main office with a three-floor building and six branch sites. The branch users all use resources at the main corporate office. Branch office employees will use wireless connections. At the main office, employees use wired and wireless connections. The customer wants the strongest authentication for employee wireless connections. It is also important that the MC role-based firewall can implement consistent access controls on employee connections no matter where the employees connect and no matter how they connect (wirelessly or, at the main site, wired). The customer also needs to provide complimentary wireless access for guests. Guest should be redirected to a portal, through which they can register and login. The customer would like two SSIDs, CompanyXEmployee and CompanyXGuest. The company wants to divide employees in two groups, managers and staff. In the corporate network, managers should only have access to Server Group Managers and staff should only have access to Server Group Staff. Each server group includes necessary services such as domain and DHCP, as well as servers that the employees access to do their jobs. All employees should also have access to the Internet. Guests should only have HTTP and HTTPS access, and only to the Internet. The customer has: a maximum of 1000 employee devices a maximum of 100 guest devices at the same time 500 devices on wired ports at the main site, which will be supported by 12 new AOS-Switches (mostly employee laptops, as well as a few non-802.1X capable printers, which should just communicate with print servers) The devices used by employees include 450 company-issued laptops, which the company wants to screen for security issues and violations of security policies. All authentications are assumed to be concurrent. To fulfill the requirements for the wireless network upgrade, the architect plans to propose: 5 RAPs at each of 6 branch sites 60 APs at the main site The architect will also propose an MM and ClearPass. The architect still needs to plan the Mobility Controllers (MCs). The customer requires high availability for wireless services and redundancy for the MCs. If a single MC fails, the network must continue to function without impact. If an MC fails, the customer must also receive a replacement component for the failed component by the next business day so that their IT staff can install it and get the network back to normal operation as soon as possible. Software upgrades must also be seamless, without the introduction of any downtime for wireless services, and the customer needs to be able to obtain the latest software over the lifetime of the solution for the next several years. Which plan for authentication meets the customer needs?
