  B. The MCs act at Layer2, and the MM acts as the default gateway.
  C. The MCs act at Layer2, and core routing switches act as the default gateway.

  B. The MCs act at Layer2, and the MM acts as the default gateway.

• Question 2:

  An architect needs to plan an 802.11ac wireless upgrade for a university building. What is one reason that it is important for the architect to identify auditoriums?

  A. Auditoriums typically require a high-density AP design for RF coverage.
  B. Users in Auditoriums often have Bluetooth devices, which can be a source of interface in the 5 GHz band.
  C. Auditoriums typically require the use of 80 MHz channels to meet bandwidth requirements.
  D. Auditoriums often require the use of DFS channels for sufficient 20 MHz channels.
  D. Auditoriums often require the use of DFS channels for sufficient 20 MHz channels.

• Question 3:

  An architect plans where to deploy new Aruba 320 Series APs at a customer site. The architect plans for the APs to be installed on the ceiling where power is inaccessible. The Ethernet cable run to these locations is CAT6, and the customer wants to support at least 1 GbE connectivity. The architect plans to connect each AP with one Ethernet port to a switch in a nearby wiring closet.

  Which feature does the switch need to support for this deployment?

  A. PoE+
  B. LACP
  C. Port channel
  D. Smart Rate
  A. PoE+

• Question 4:

  Refer to the exhibit.

  

  An architect needs to plan a network solution for a new office building with four floors. Each floor has two wiring closets with the equipment shown in the exhibit. The switches will connect to employee desktops, a few campus APs controlled by MCs, and printers. The switches do not implement tunneled node.

  What is a best practice design for the VLANs and subnets for the wired devices?

  A. one VLAN per closet and a /24 subnet for each VLAN
  B. one VLAN per closet and a /25 subnet for each VLAN
  C. one VLAN for the entire building and a /23 subnet
  D. one VLAN per floor and a /24 subnet for each VLAN
  B. one VLAN per closet and a /25 subnet for each VLAN

• Question 5:

  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.
  B. Clustering provides high stability because one MC is active for all sessions and one is standby for all sessions.

• Question 6:

  An enterprise needs an upgrade to 802.11ac. Users run applications such as Web, email, voice, and video. The architect needs to conduct an active site survey to plan 802.11ac AP locations. The noise floor is about -90 dBm across the site. Based on Aruba best practices, what is the minimum acceptable signal that the architect should look for to determine the test AP range?

  A. a signal of -65 dBm in the 2.4 GHz band
  B. a signal of -75 dBm in the 5 GHz band
  C. a signal of -65 dBm in the 5 GHz band
  D. a signal of -75 dBm in the 2.4 GHz band
  C. a signal of -65 dBm in the 5 GHz band

• Question 7:

  Refer to the exhibit.

  

  The customer needs to expand its wired and wireless network to a new building, Building 2, which is near the existing building, Building 1. The exhibit shows the logical plan that the architect has created so far. The aggregation layer switches in the new building should provide the default gateway services for the VLANs in the new building and route traffic to the core. The existing Aruba Mobility Controllers (MCs) will control the new APs.

  What should be the VLAN assignment for Link 1, indicated in the exhibit?

  A. an unused VLAN such as 200
  B. VLANs 21, 22, and 23 only
  C. VLANs 11, 12, 13, 21, 22, and 23
  D. the default VLAN and VLAN 14
  C. VLANs 11, 12, 13, 21, 22, and 23

• Question 8:

  A customer needs a networking solution that supports their Microsoft Skype for Business Unified Communications (UC) solution. The architect plans to use multiple Aruba APs, switches, and controllers.

  The customer wants real time statistics and assessment of call quality.

  Which component should the architect include to provide these services?

  A. Aruba AirWare
  B. Aruba Central
  C. Aruba Mobility Master (MM)
  D. Aruba ClearPass
  B. Aruba Central

• Question 9:

  Which guidelines should an architect use to determine how many AirWave servers to recommend?

  A. One server should be deployed on every subnet with an infrastructure device.
  B. One server is recommended for the base features and one server each for add-on features such as Clarity.
  C. One server should be dedicated to the wired infrastructure and one server to the wireless infrastructure.
  D. One server should monitor and manage up to about 4,000 infrastructure devices.
  A. One server should be deployed on every subnet with an infrastructure device.

• Question 10:

  For which scenario does the Aruba backplane stacking technology meet the needs?

  A. The customer needs to deploy a pair of aggregation switches in the same closet, and wants to simplify the architecture and redundancy design.
  B. The customer needs to simplify the deployment of core switches which are located in different closets for redundancy purposes.
  C. The customer needs to expand the network and make it possible for the current core switches to support more MAC forwarding and ARP entries.
  D. The customer needs to deploy a switch at a branch office and have the switch automatically discover and join the network stack at the main office.
  B. The customer needs to simplify the deployment of core switches which are located in different closets for redundancy purposes.
