  A. OSPF graceful restart
  B. SmartLink
  C. BGP
  D. VRRP
  C. BGP

• Question 16:

  An architect needs to plan the bandwidth for two Aruba 7240 Mobility Controllers (MCs) which will connect to the network core. The customer indicates that four 10 GbE links between the network core and the data center will be adequate. The customer expects almost all traffic in the network will be wireless. The customer expects up to 25 Gbps upstream traffic from wireless clients and up to 35 Gbps downstream to wireless clients. The customer requires the MCs to be able to continue to forward traffic if up to one link fails, but lower performance during the failover situation is permissible.

  What are the minimal links to meet these requirements?

  A. two 10 GbE links on each of the MC
  B. two 40 GbE links in each of the MCs
  C. three 10 GbE links on each of the MCs
  D. four 10 GbE links on each of the MCs.
  B. two 40 GbE links in each of the MCs

• Question 17:

  Read this scenario thoroughly, and then answer each question that displays on the right side of the screen.

  An architect proposes these products for a customer who wants a wireless and wired upgrade:

  1.

  Aruba 2930M switches at the access layer

  2.

  Aruba 5406R switches at the core

  3.

  Aruba AP-325s

  4.

  Aruba 7205 Mobility Controllers (MCs), deployed in a cluster

  5.

  Aruba Mobility Master (MM)

  6.

  Aruba ClearPass Cx000V

  7.

  Aruba AirWare

  The architect also needs to propose a security plan for the solution. The customer has 900 employees and up to 30 guests a day. The customer wants to protect the internal perimeter of the network with authentication and simple access controls. The customer is most concerned about wireless security, but also wants to ensure that only trusted users connect on the wire. However, the customer also wants all wired traffic to be forwarded locally on access layer switches. The customer already has a third-party firewall that protects the data center.

  The customer wants to use certificates to authenticate user devices, but is concerned about the complexity of deploying the solution. The architect should recommend a way to simplify. For the most part users connect company-issued laptops to the network. However, users can bring their own devices and connect them to the network. The customer does not know how many devices each user will connect, but expects about two or three per-user. DHCP logs indicate that the network supports a maximum of 2800 devices.

  Refer to the provided scenario. Based on the plan for wired authentication, what is a correct plan for wired user VLANs?

  A. use the MCs to assign wired users to their VLANs, and extend the VLANs to a Layer 3 switch connected to the MC
  B. specify the VLANs in network policies on AirWare, and ensure that both the switches and MCs are managed by AirWare
  C. assign wired users to different VLANs from wireless users, based on port or role assignments on access layer switches. Extend the VLANs to the core.
  D. configure the same roles on switches and MCs to place wired and wireless users in the same VLANs. Extend VLANs from access layer switches to the core.
  C. assign wired users to different VLANs from wireless users, based on port or role assignments on access layer switches. Extend the VLANs to the core.

• Question 18:

  A customer needs a wired network solution that can recognize and prioritize a wide array of different types of traffic, including casual Web browsing, voice, video, SAP Online, and file sharing.

  The architect needs to choose between the Aruba 2930F or the 2540 Switch Series for the access layer switch.

  Why would the architect choose the 2930F rather than the 2540 Switch Series for this customer?

  A. The 2930F Series supports LLDP-MED for detecting VoIP traffic, while the 2540 Series does not.
  B. The 2930F Series supports advancing routing, including multi-area OSPF, while the 2540 Series does not.
  C. The 2930F Series supports more options for class-based QoS policies that the 2540 Series.
  D. The 2930F Series can provide better congestion management with its much deeper buffers.
  D. The 2930F Series can provide better congestion management with its much deeper buffers.

• Question 19:

  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?

  A. 5-10
  B. 10-15
  C. 20-25
  D. 40-45
  D. 40-45

• Question 20:

  An architect plans 12 APs for an auditorium that is 325 square meters (3, 498 square feet). Each AP has one 2.4 GHz radio and one 5 GHz radio. Both types of radios use 20 MHz channels.

  Assume that DFS channels can be used in this design.

  How many 5 GHz collision domains does this design provide?

  A. 1
  B. 6
  C. 12
  D. 25
  B. 6
