Exam 11: Designing HPE Nimble Solutions

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 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 customer needs a solution to terminate VPN tunnels for Aruba RAPs. The customer has a single site and a single public IP address for this purpose. Network address translation (NAT) will forward the IPsec traffic to the correct device to terminate the VPN tunnel. The customer also requires N+1 redundancy for the solution. Which solution meets the customer requirements?

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 customer requires APs that meet these minimal criteria: Support for MU-MIMO Support for up to four spatial streams, both when MU-MIMO is used and when it is not used Support for transmissions to up to three MU-MIMO clients at the same time The architect finds these specifications for the two models under consideration: AP-335 = 4x4:4:4:3 AP-325 = 4x4:4:3:3 What should the architect determine from these specifications?

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?

An architect proposes the following Aruba solutions: Two Virtual Mobility Masters (VMMs) Six 7030 Mobility Controllers (MCs) 300 APs In addition to any necessary AP, PEF, and RFP licenses, which license package should the architect propose?

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?

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?

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?

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?

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?

For which scenario should an architect recommend Aruba Central Managed Portal (MSP)?

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?

Refer to the exhibit. An architect selects 5406R switches for the aggregation layer. What is an appropriate amount of bandwidth for the link aggregation between each aggregation layer VSF fabric and the campus core?

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?

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?

A customer needs an 802.11ac upgrade for an office with cubicles. The customer states that, because they planned locations for the existing 802.11n APs so that there are no coverage holes, they will simply deploy the new 802.11ac APs in the same location as the existing APs. The customer plans to support mobile devices in addition to laptops. What should the architect explain about shy a site survey is desirable to determine the optimal locations for the new APs?
