HP HP Certifications HPE6-A47 Questions & Answers

• Question 61:

  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?

  A. two Aruba MCs on the same subnet that use VRRP without clustering

  B. two Aruba MCs deployed as a Layer 3 cluster

  C. two Aruba MCs on different subnets that use VRRP without clustering

  D. two Aruba MCs deployed as a Layer 2 cluster

  Correct Answer: B

• Question 62:

  An architect proposes four 7210 Mobility Controllers (MCs) to support about 1,500 client APs. The customer environment will have a maximum of about 20,000 wireless clients. The customer wants hardware MMs with an active and standby deployment.

  What is the minimum solution that meets the customer requirements?

  A. two MM-HW-10K appliances

  B. two MM-HW-5K appliances

  C. four MM HW-5K appliances

  D. four MM HW-10K appliances

  Correct Answer: B

• Question 63:

  An architect learns that a customer site is 14,307 square meters (154,000 square feet) and supports 900 employees using WiFi 5 Ghz radio. What additional information should the architect collect to create the RF plan?

  A. number of devices used by each user

  B. the OS used on wireless devices

  C. whether BLE wayfinding is required

  D. software version on Mobility Controllers (MCs)

  Correct Answer: A

• Question 64:

  An architect needs to help a customer design a management and monitoring solution for an Aruba network

  in an airport. The solution consists of an Aruba Mobility Master (MM), Aruba 7210 MCs, Aruba AP-335s,

  and Aruba 5496R switches.

  The architect plans to recommend Aruba AirWare.

  The airport has a high-client device turnover and many highly mobile devices. Which changes should the

  architect make to the recommended solution based on this characteristic?

  A. Recommend additional hardware resources beyond those recommended for the typical tested AirWare platform.

  B. Recommend extra AirWare device licenses to support the changing number of client devices.

  C. Recommend Aruba Central with a Clarity subscription as a more flexible cloud-based solution.

  D. Recommend Aruba Central with guest access licensing to increase guest visibility.

  Correct Answer: B

• Question 65:

  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.

  Correct Answer: B

• Question 66:

  An architect plant to purpose an Aruba wireless solution with several Mobility Controllers (MCs) and a Mobility Master (MM) architecture. Wireless users run Skype for Business, a Unified Communications (UC) solution. The architect plans to use the Aruba SDN capabilities to integrate with the UC solution.

  What helps to support high availability specifically for the SDN services?

  A. a redundant master MC

  B. backup controllers defines on the APs

  C. a cluster deployment for MCs

  D. a redundant MM

  Correct Answer: D

• Question 67:

  Refer to the exhibit.

  Exhibit 1 shows the logical plan, and Exhibit 2 shows the BOM created with IRIS. An architect plans to propose two 5406Rzl switches as a VSF fabric for a campus network core. Which issue with the plan should the architect correct?

  

  A. Add two QSPF+ MP0 SR4 transceivers.

  B. Change the v2 modules to v3 modules.

  C. Add stacking modules and cables.

  D. Change the power supply type.

  Correct Answer: B

• Question 68:

  Which guidelines should an architect use to determine how many AirWave servers to recommend?

  A. One server should be deployed on every subnet with an infrastructure device.

  B. One server is recommended for the base features and one server each for add-on features such as Clarity.

  C. One server should be dedicated to the wired infrastructure and one server to the wireless infrastructure.

  D. One server should monitor and manage up to about 4,000 infrastructure devices.

  Correct Answer: A
