• Question 11:

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

  A. A customer has wired IoT devices and wants to be able to control their access. The architect recommends sending all of their traffic through the MC role-based firewall.
  B. A customer wants to manage their AOS-Switches in a more centralized manner. They would like to connect AOS-Switches to AirWave over secure IPsec tunnels and control all configuration from there.

• Question 14:

  A hospital needs an upgrade to 802.11ac for its wireless network, which needs to provide complete coverage. The hospital has a concrete exterior and uses drywalls for all of the interior walls with a few exceptions as mandated for safety. The building has 10 foot (3m) ceilings. The legacy APs were deployed in the hallway, but the customer is open to deploying APs in any room such as reception areas, patient rooms, operating rooms, treatment rooms, and lounges. The wireless network must support wireless medical devices, voice communicators for medical staff, laptops in nurse stations, medical staff tablets, and visitor and patient personal devices. All of these devices support both the 2.4GHz and 5GHz band. The exhibits below show one wing of one floor of the hospital. This wing is about 14,000 square feet (1300 sq. m). This area has up to: 40 concurrent patients and visitors, who might have up to two devices 40 concurrent staff members, who might have up to three devices About 100 medical and other types of wireless devices

  Several of these wireless medical devices are in the X-ray and X-ray control rooms. The architect has already planned to place APs in stairwells on another floor.

  Which AP plan for this wing of this floor meets the customer needs?

  

  A. B.
  C. D.
  D

• Question 15:

  Case study

  A customer needs a wireless network upgrade for 802.11ac and possibly an upgrade to the wired network. The customer requires dual-radio 802.11ac APs, each radio of which can support 4x4 MIMO at full feature set.

  The customer has given architects this information about their wireless devices:

  2700 IoT devices which will have only wireless connections; they support WPA2 with 802.1X

  300 on each floor in 3 buildings with 3 floors each

  5,400 users, who use devices such as laptops and smartphones

  600 users on each floor in 3 buildings with 3 floors each

  24 security cameras which will have only wireless connections; they support WPA2 with 802.1X and have a local power source

  4 on floor 1 of each of the 3 buildings

  2 on the other 6 floors

  The architect also has collected information about the existing wired network.

  The existing access layer switches support these features:

  10/100/1000 edge ports

  PoE (802.3af)

  1GbE fiber uplinks

  The existing aggregation switches support these features:

  1/10GbE fiber ports

  ARP tables up to 64,000

  The customer has provided this figure that shows the existing cabling between floors and between buildings:

  

  Each floor is about 100 feet (30 m) by 140 feet (43 m) with a 10 foot (3 m) ceiling. Interior walls are drywall. The layout for each floor is similar to that shown below. CAT5e cable is extended to all areas.

  

  The customer wants to have a wired upgrade as well. The customer has indicated some additional requirements for the wired network, including redundancy for all switch-to-switch links. The customer also wants to explore whether the aggregation layer in buildings can be eliminated.

  What is one missing piece of information the architect should obtain from the customer before they design the solution and select new switches and their accessories?

  A. the power requirements on the wireless security cameras
  B. the number of fiber strands for fiber runs
  C. the percentage of time that employees use their wired connection
  D. the power rating on the fiber deployed between buildings
  C. the percentage of time that employees use their wired connection

• Question 16:

  Refer to the exhibit.

  

  A customer has a wired infrastructure shown in the exhibit. The customer is in the process of expanding their wireless services. They will now add a new wireless solution, with mobility controllers (MCs) connected as shown. The new wireless

  solution will support a total of 450 APs and about 26,000 wireless devices. It must provide seamless roaming across the entire campus.

  After the new deployment, both wired and wireless devices experience IP connectivity issues.

  Which change to the existing infrastructure should the architect recommend to support all of the customer requirements?

  A. The MCs should be moved to the aggregation layer, and more MCs added.
  B. The core and aggregation switches should disable Virtual Switching Framework (VSF).
  C. The core switches should be replaced with switches that have larger ARP tables.
  D. The wired VLANs should be combined into a single VLAN and /16 subnet.
  B. The core and aggregation switches should disable Virtual Switching Framework (VSF).

• Question 17:

  Refer to the exhibit.

  

  A writing closet needs to support these devices: 100 desktops 5 printers 20 AP-345s

  The customer wants to single-home the AP-345s and support higher than 1GbE speeds on the AP connections to future proof. The customer also requires that the closet have two 10GbE links to the core with SR transceivers. The exhibit shows the preliminary plan for this closet.

  Which correction should the architect make to the plan to meet the customer requirements?

  A. Change all of the switches to the Aruba 2930M 40G 8 HPE Smart Rate PoE+ 1-Slot Switch.
  B. Change one switch to the 2930M 24-port Smart Rate PoE+ model.
  C. Add a 4-port SFP+ module to one of the switches.
  D. Add a Smart Rate module to each of the switches.
  C. Add a 4-port SFP+ module to one of the switches.

• Question 18:

  

  A hospital needs an upgrade to 802.11ac for its wireless network. The wireless network supports:

  wireless medical devices medical staff voice communicators laptops in nurse stations medical staff tablets visitor and patient personal devices

  All of these devices support both the 2.4GHz and 5GHz band. Assuming about a max throughput of 150 Mbps per AP, the hospital would like to support about 4 Mbps per client. The architect has used VisualRF to plan the AP placement on one of the floors, which the hospital expects will need to support about 800 wireless devices. The exhibits show heatmaps from this plan. The architect also plans to deploy APs in stairwells between floors.

  How well does the plan meet the requirements?

  A. The current AP placement fails to account for the lead-lined walls that are common in patient and exam rooms.
  B. The current AP placement fails to provide adequate signal for the voice communicators in several areas.
  C. The current AP placement meets coverage requirements, but does not meet capacity requirements.
  D. The current AP placement meets the customer requirements in terms of coverage and capacity.
  D. The current AP placement meets the customer requirements in terms of coverage and capacity.

• Question 19:

  Refer to the exhibit.

  

  A customer needs a wireless network upgrade and has these requirements: Support any applications used on a wired connection Support up to 2500 wireless clients Support seamless roaming from floor to floor and building to building Continue to function seamlessly if one AP or controller fails

  The architect has designed the local infrastructure for the network as shown in the exhibit.

  Which change should the architect make to better meet customer requirements and best practices?

  A. Combine the /24 subnets for wireless and wired users into a /16 subnet.
  B. Place each controller in a different VLAN and subnet.
