Refer to the exhibit.
An architect needs to design the topology for a new wired network at a campus with three buildings. The exhibit above shows the cabling layout. The customer requires link redundancy at all layers, up to one switch-to-switch link can fail without an effect on client connectivity. The architect has determined that the closet of each floor should have three Aruba 2930M switches, and the core will use Aruba 5406 switches. The aggregation layer, if used, will use Aruba 3810M switches. However, the customer prefers the elimination of the aggregation layer and has asked the architect to advise the impact of the elimination of this layer.
Where would the elimination of the aggregation layer require rewriting?
A. All of the buildings
B. Building 1 and Building 2 only
C. Building 1 and Building 3 only
D. Building 3 only
Refer to the exhibit.
A museum wants to add full 802.11ac wireless coverage across the building, which is about 210 feet (64 m) by 330 feet (100m). The museum has 15-foot (4,6 m) ceilings and stone interior walls. The network needs to support up to 600 wireless guest devices. The exhibit also shows a preliminary plan for AP locations. The museum has eight Ethernet drops in the lobby and gift shop, but has otherwise not been wired.
What is one recommendation that the architect should make to ensure a successful deployment?
A. use of directional antennas to avoid lost signal
B. addition of a writing closet closer to the north side
C. use of at least CAT5 cable to connect to the APs
D. addition of about 10 APs to achieve adequate density
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?
A. Add APs in a dedicated AP group to support only the guest network SSID.
B. Have a dedicated mobility controller in the DMZ managed by the same MM.
C. Double the number of APs and controllers
D. Use MultiZone, and put a mobility controller in the DMZ.
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?
A. Employee SSID = WPA2-802.1X, Guest SSID = WPA2-PSK, Wired edge ports = No authentication
B. Employee SSID = WPA2-802.1X, Guest SSID = Captive portal, Wired edge ports = No authentication
C. Employee SSID = WPA2-802.1X, Guest SSID = Captive portal, Wired edge ports = 802.1X + MAC-Auth
D. Employee SSID = WPA2-PSK, Guest SSID = MAC-Auth, Wired edge ports = MAC-Auth
Case study
