Question1: An architect proposes an Aruba wireless solution for a customer that uses Microsoft Skype for Business. What should be set up on the MCs, or MM, to ensure that wireless voice traffic is properly prioritized?

Question2: What typically drives the need for an aggregation layer in modern networks?

Question3: For which scenario does the Aruba backplane stacking technology meet the needs?

Question4: 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?

Question5: 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?

Question6: A plan includes these security settings for the employee WLAN:
WPA2-Enterprise with AES encryption
802.1X with PEAP-MSCHAPv2
However, the customer wants to use certificates to authenticate user devices. Which change brings the plan in alignment with the customer requirements?

Question7: A customer has several clusters of Aruba 325 Instant APs. The customer is happy with the performance of the current APs, but would like to add a Mobility Controller (MC). What should the architect propose?

Question8: Refer to the exhibit.

The exhibit shows the current plan for a wired network upgrade.
As much as possible, the customer wants to flatten the architecture and avoid recabling. However, each Building 2 switch must also maintain connectivity to the core if one link fails. What should the architect propose to meet the customer requirements?

Question9: An architect needs to deliver an upgrade to an 802.11ac-based solution for a customer. The customer requires an active site survey for the new deployment. Which deliverable should the architect provide to the customer?

Question10: An architect proposes an Aruba solution with a hardware Mobility Master (MM) to a customer. The customer has a disaster recovery site which is connected to the main site at Layer 3. The customer requires the MM to remain available in case of a total site failure.
Which plan meets the customer requirements?

Question11: 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:
Aruba 2930M switches at the access layer
Aruba 5406R switches at the core
Aruba AP-325s
Aruba 7205 Mobility Controllers (MCs), deployed in a cluster
Aruba Mobility Master (MM)
Aruba ClearPass Cx000V
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.
Which solution should the architect recommend on the 2930M switches to authenticate and control wired employee devices?

Question12: A customer requires a wireless upgrade. The architect proposes:
Aruba AP-325s
Mobility Controller (MC) 7210s
Virtual Mobility Masters (MMs)
ClearPass
AirWave
The customer is interested in wired authentication, as well as wireless authentication, but does not have the budget to upgrade the wired network. The wired network does not currently support 802.1X or RADIUS.
Which feature of the Aruba solution should the architect explain to justify the proposed solution?

Question13: An architect plans to purpose two Aruba Mobility Controllers (MCs) in a cluster. The customer has a large building that needs to support about 10,000 devices. The architect plans to associate the Employees WLAN with VLAN ID 10.
What is one Aruba best practice for this design?

Question14: A customer currently has an Instant AP deployment. Which customer requirement would indicate that the customer needs to add a controller to the deployment?

Question15: 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?

Question16: 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?

Question17: Refer to the exhibit.

An architect determines that 80 Gbps bandwidth is required for the link aggregation between the Building
1aggregation layer and Building 2. Which transceivers should the architect recommend for each pair of switches?

Question18: 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?

Question19: The customer has an office environment with users who have laptops that can connect with wired or wireless.
Users also bring one or two of their own devices. An architect creates a proposal with Aruba AP-325s, 7210 Mobility Controllers (MCs), a Mobility Master (MM), and Aruba 2930M switches at the access layer to support the laptops and APs.
The architect plans to recommend 802.1X authentication without tunnelled node on Aruba 2930M switch ports that connect to laptops. What is one advantage of this form of authentication?

Question20: Refer to the exhibit.

The customer requires fast failover if any one link or core device fails. Which additional technology should the architect plan on the core VSF fabric to meet these criteria?

Question21: 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?

Question22: 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?

Question23: Refer to the exhibit.
Exhibit 1.

Exhibit 2.

Exhibit 1 shows the logical plan, and Exhibit 2 shows the BOM that the administrator has made in Iris. What is missing from the IRIS BOM?

Question24: Refer to the exhibit.

What is one reason for an architect to recommend the use of Virtual Switching Framework (VSF) in this network?

Question25: Which benefit does Aruba AirWare Clarity provide to customer IT staff?

Question26: An RF plan specifies wide sector directional antennas.
Refer to the antenna specifications.
H-plane refers to the Azimuth or Horizontal plane and E-plane refers to Elevation or Vertical plane.
Antenna 1: H-plane = 360; E-plane = 120
Antenna 2: H-plane = 360; E-plane = 60
Antenna 3: H-plane = 100; E-plane = 90
Antenna 4: H-plane = 60; E-plane = 60
Which antenna specifications indicate that the antenna is a good choice for the plan?

Question27: An Aruba wireless solution for a very high density (VHD) wireless solution consists of a Mobility Master (MM) and two Mobility Controllers (MCs). What is the best practice design for routing the wireless traffic?

Question28: An architect needs to plan the RF coverage. Which application has the greatest potential impact on RF design?
