HP HP Certifications HPE6-A47 Questions & Answers

• Question 51:

  Refer to the exhibit.

  

  The customer needs to expand its wired and wireless network to a new building, Building 2, which is near the existing building, Building 1. The exhibit shows the logical plan that the architect has created so far. The aggregation layer switches in the new building should provide the default gateway services for the VLANs in the new building and route traffic to the core. The existing Aruba Mobility Controllers (MCs) will control the new APs.

  What should be the VLAN assignment for Link 1, indicated in the exhibit?

  A. an unused VLAN such as 200

  B. VLANs 21, 22, and 23 only

  C. VLANs 11, 12, 13, 21, 22, and 23

  D. the default VLAN and VLAN 14

  Correct Answer: C

• Question 52:

  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.

  Which component should the architect include to provide these services?

  A. Aruba AirWare

  B. Aruba Central

  C. Aruba Mobility Master (MM)

  D. Aruba ClearPass

  Correct Answer: B

• Question 53:

  An architect plans 12 APs for an auditorium that is 325 square meters (3, 498 square feet). Each AP has

  one 2.4 GHz radio and one 5 GHz radio. Both types of radios use 20 MHz channels.

  Assume that DFS channels can be used in this design.

  How many 5 GHz collision domains does this design provide?

  A. 1

  B. 6

  C. 12

  D. 25

  Correct Answer: B

• Question 54:

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

  A. insufficient fiber cabling, especially between buildings

  B. lack of high speed uplink capabilities at the access layer

  C. simplification of spanning tree protocol ad the access layer

  D. need to extend VLANs across wider areas

  Correct Answer: C

• Question 55:

  A customer requires APs that meet these minimal criteria:

  1.

  Support for MU-MIMO

  2.

  Support for up to four spatial streams, both when MU-MIMO is used and when it is not used

  3.

  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 = 4x4:4:4:4:3 AP-325 = 4x4:4:4:3:3

  What should the architect determine from these specifications?

  A. The AP 335 and the AP 325 do not meet the customer requirements, so consider a different model.

  B. The AP 325 meets the customer requirements, but the AP 335 does not.

  C. Either the AP 335 or the AP 325 meet the customer requirements.

  D. The AP 335 meets the customer requirements, but the AP 325 does not.

  Correct Answer: C

• Question 56:

  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?

  A. Deploy a hardware MM to the disaster recovery site and set up VRRP between them.

  B. Deploy a hardware MM to the disaster recovery site and set its IP address as the standby master for MCs.

  C. Deploy the virtual MM (VMM) to the disaster recovery site and set the VMM IP address to the same address as the hardware MM.

  D. Deploy the virtual MM (VMM) to the disaster recovery site and configure clustering on the hardware and software appliances.

  Correct Answer: A

• Question 57:

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

  A. for a service provider who needs to monitor multi-vendor environments

  B. for an enterprise that needs to manage data center services together with the network

  D. for an enterprise with many branches that needs to manage services centrally

  Correct Answer: D

• Question 58:

  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 AP325s, 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 tunneled node on Aruba 2930M switch ports that connect to laptops.

  What is one advantage of this form of authentication?

  A. ensures that Aruba firewall policies apply to wired user traffic.

  B. prevents users from connection attempts with more than three devices

  C. enables user access control and ensures only authorized users connect.

  D. provides a second layer of protection for wireless users at the internal perimeter

  Correct Answer: C
