01. What typically drives the need for an aggregation layer in modern networks?
a) lack of high speed uplink capabilities at the access layer
b) insufficient fiber cabling, especially between buildings
c) simplification of spanning tree protocol ad the access layer
d) need to extend VLANs across wider areas
02. An architect needs to plan 802.11ac wireless deployment for an office environment with a mix of closed offices and cubicles. The coverage area is approximately 4,645 square meters (approximately 50,000 square feet) and has 350 users.
The employees use the wireless network for typical office applications, such as email, Web, printing, and accessing shared files and datacenter services. The architect plans to do a predictive site survey and use VisualRF to plan the coverage.
What is a general estimate for the AP count that the architect should have in mind?
03. A customer has high security needs, so the network architect proposes dedicated Air Monitors (AMs). What is one additional benefit of the AMs that the architect can explain?
a) If a nearby AP fails, the AM can automatically convert to AP mode to fill in the coverage gap.
b) The AMs can detect a broad range of RF interference and give administrators help in determining the source.
c) During normal operation, the AMs can support clients, as well as detect and mitigate threats on any channel.
d) An AM can help in troubleshooting because it stores detailed statistics about wireless traffic locally.
04. For which scenario does an Aruba VIA client provide the solution?
a) A customer needs an easy-to-use wireless solution that enables remote workers to connect to the same SSID at the corporate office and at home.
b) A customer has many telecommuters who take laptops on and offsite and needs a solution to check the security compliance and health of these laptops.
c) A customer needs to let traveling workers connect to the Internet anywhere and receive secure access to the main site.
d) A customer needs a client that will simplify connections to the wireless network at the main site no matter what type of authentication the SSID requires.
05. A customer needs a wireless refresh for 802.11ac. The customer site has about 3,000 wireless devices, and the network architect plans to propose 200 APs. The architect also plans to propose two Virtual Mobility Controllers (VMCs) and a Virtual Mobility Master (VMM).
Which licenses should the architect propose for this solution?
a) Four LIC-MM-VA-1K; Four LIC-MC-VA-50; 200 Enterprise
b) Five LIC-MM-VA-50; Four LIC-MC-VA-50; 200 Enterprise
c) Five LIC-MM-VA 50; Four LIC-MC-VA 50 and no Enterprise required
d) Five LIC-MM-VA-50; 200 Enterprise and no LIC-MC-VA required
06. An architect needs to plan an 802.11ac upgrade for an office building. The customer has requested an active survey. Which approach should the architect take to determine the cell edges?
a) Set the test AP to the maximum transmit power and use the 2.4 GHz signal to determine the cell edges.
b) Set the test AP to the minimum transmit power and use the 2.4 GHz signal to determine the cell edges.
c) Set the test AP to the maximum transmit power and use the 5 GHz signal to determine the cell edges.
d) Set the test AP to the minimum transmit power and use the 5 GHz signal to determine the cell edges.
07. A customer requires high availability for wireless services, including stateful failover for user connections if the Mobility Controller (MC) that handles the user traffic fails.
What is the requirement for the design?
a) MCs are deployed in a cluster, and they are on the same VLAN
b) MCs are distributed across each VLAN on which APs are deployed and have VRRP enabled
c) MCs have a standby master IP address assigned to them
d) MCs have enough licenses to support the APs for which they are active and standby MC.
08. 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?
a) a redundant master MC
b) backup controllers defines on the APs
c) a cluster deployment for MCs
d) a redundant MM
09. A customer has very high availability requirements for wireless services. The architect plans to implement clustering on several Aruba Mobility Controllers (MCs).
Which benefit of this feature should the architect explain?
a) Clustering provides wireless client load balancing and seamless failover for client sessions
b) Clustering provides high stability because one MC is active for all sessions and one is standby for all sessions
c) Clustering enables an AP with a failed MC to operate on its own briefly to ensure seamless connectivity.
d) Clustering enables an AP with a failed MC to reconnect to a new AP after a short bootstrap
10. For which scenario should an architect recommend Aruba Central Managed Portal (MSP)?
a) for a service provider who needs to monitor multi-vendor environments
b) for an enterprise that needs to manage data center services together with the network
c) for a service provider who needs to manage multiple customer networks
d) for an enterprise with many branches that needs to manage services centrally
