• Question 4:

  An architect simulates VoIP calls and tests the throughput as 67 Kbps, packet loss as 0.3 percent, maximum latency as 100 ms, and maximum jitter as 100 ms. Which issue typically causes a poor experience for users?

  A. the packet loss
  B. the throughput
  C. the latency

• Question 5:

  A customer currently has an Instant AP deployment.

  Which customer requirement would indicate that the customer needs to add a controller to the deployment?

  A. the requirement to apply role-based firewall policies
  B. the requirement for a captive portal for guests
  C. the requirement to provide client-to-site VPN acces for remote users
  D. the requirement for a cloud-based management solution
  D. the requirement for a cloud-based management solution

• Question 6:

  What is a key criteria that an architect should use to choose between an Aruba 7000 Series or 7200 Series Mobility Controller (MC)?

  A. the number of wireless devices that the MC needs to support
  B. whether the MC needs to terminate VPN tunnels
  C. the need to deploy controllers in a cluster
  D. whether the MC needs to support advanced 8.x features
  A. the number of wireless devices that the MC needs to support

• Question 7:

  Refer to the exhibit.

  

  A customer needs to upgrade the wireless network at their campus, which has a single large building. Employees use the wireless network to access the Internet and centralized services. The building has four floors. These are the requirements: 30 APs on each floor A Mobility Master (MM)-based architecture Deployment of one Aruba 7030 Mobility Controller (MC) on each floor, with the MCs combined in a cluster for seamless client failover and roaming

  What should the architect explain to the customer about the proposed solution?

  A. MCs should be deployed centrally on the same VLAN to better meet these goals
  B. MCs in a cluster must have additional AP licenses to support APs of a failed controller
  C. The MC 7030 does not support enough APs for the requirements
  D. The MC 7030 only supports clusters with up to three members
  A. MCs should be deployed centrally on the same VLAN to better meet these goals

• Question 8:

  Which benefit does Aruba AirWare Clarity provide to customer IT staff?

  A. assesses times for clients to obtain DHCP and DNS services to help staff diagnose non-WiFi related issues
  B. create a heat map of RF coverage, shows places with interfaces, and helps staff pinpoint the interference source
  C. provides insight into the security posture of clients connected to the network, whether wired or wireless
  D. maps all network devices, including APs, MCs, switches, and client devices, and provides information about each node
  A. assesses times for clients to obtain DHCP and DNS services to help staff diagnose non-WiFi related issues

• Question 9:

  An architect plans to deploy a Mobility Controller (MC) at one building in subnet 10.23.01.0/24 and another MC in another building in subnet 10.44.12.0/24. The MCs need to provide redundancy for each other. What must the architect take into account in the redundancy plan?

  A. The MCs cannot provide any level of redundancy for each other unless one is moved into the other's subnet.
  B. The MCs cannot be in a cluster, and they must use Virtual Router Redundancy Protocol (VRRP) to provide redundancy for each other.
  C. The MCs can be in a cluster, but the cluster will not support features such as stateful failover.
  D. Each MC can be the backup LMS for the other MCs' APs, but it cannot be in a cluster with the other MC.
  B. The MCs cannot be in a cluster, and they must use Virtual Router Redundancy Protocol (VRRP) to provide redundancy for each other.

• Question 10:

  A customer needs a networking solution that supports their Microsoft Skype for Business Unified Communications (UC) solution. The architect discovers that user wireless devices are Wi-Fi Multimedia (WMM) capable. Windows policies assign voice traffic DSCP 46 and video traffic DSCP 34.

  Which potential issue should the architect explain to the customer about the default QoS settings?

  A. The DSCP values place both voice and video traffic in the video VMM queue, so voice does not receive the prioritization that is should.
  B. The Aruba APs and controllers use different prioritization mechanism from WMM, so they will not accept high priority traffic from the wireless devices.
  C. DSCP is incompatible with WMM. The Aruba APs and controllers instead use 802.1p to mark traffic to and from wireless devices.
  D. The DSCP for wireless client traffic is concealed within the GRE packet on the path from the AP to the controller, and does not take effect.
  A. The DSCP values place both voice and video traffic in the video VMM queue, so voice does not receive the prioritization that is should.
