HP HP Certifications HPE6-A47 Questions & Answers

• Question 31:

  An architect has an Instant AP (IAP) cluster at a mid-sized branch office. The IAP cluster now needs to tunnel corporate traffic to a Mobility Controller (MC) at the main office. However, the branch office should remain functional even if the link to the main office fails. Users at the branch office require access to main office resources, but do not require multicast services.

  What is the recommended DHCP mode?

  A. Local

  B. Centralized L2

  C. Distributed L2

  D. Distributed L3

  Correct Answer: D

• Question 32:

  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?

  A. An 802.11ac deployment typically works better with side-mounted, rather than ceiling-mounted, APs, and a site survey will help determine the new mounting locations.

  B. The new 802.11ac deployment should have a capacity-based design for the best performance, but the existing deployment sounds like a coverage-based design.

  C. 802.11ac AP radios tend to be more sensitive to 2.4 GHz interference than 802.11n APs, so the architect needs to search for all potential sources of such interference.

  D. 802.11ac APs can support a higher density of clients, so they can be deployed farther apart than the APs in most existing 802.11n deployments.

  Correct Answer: A

• Question 33:

  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?

  A. 60 Gbps

  B. 160 Gbps

  C. 200 Gbps

  D. 320 Gbps

  Correct Answer: C

• Question 34:

  A plan includes these security settings for the employee WLAN:

  1.

  WPA2-Enterprise with AES encryption

  2.

  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?

  A. Use EAP-TLS instead of PEAP-MSCHAPv2

  B. The TKIP encryption instead of AES.

  C. Add WPA2-PSK as an alternative to WPA2-Enterprise.

  D. Add Tunneled TLS (TTLS) as an alternative to PEAP-MSCHAPv2.

  Correct Answer: D

• Question 35:

  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?

  A. Antenna 1

  B. Antenna 2

  C. Antenna 3

  D. Antenna 4

  Correct Answer: B

• Question 36:

  An architect needs to plan a very high density (VHD) wireless network at a large events venue, at which thousands of attendees are expected. The architect plans to deploy a cluster of Mobility Controllers (MCs) to control the APs. It is important to support seamless roaming for wireless devise across the venue.

  What should the architect ensure for the network services?

  A. DHCP servers can support a high number of scopes with a /24 size.

  B. A third-party firewall integrates with ClearPass to filter the guest user traffic.

  C. A domain CA is set up to deploy certificates to a high volume of guest devices.

  D. DHCP and DNS servers are carrier-grade and support a low transaction time.

  Correct Answer: B

• Question 37:

  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?

  A. a signal of -65 dBm in the 2.4 GHz band

  B. a signal of -75 dBm in the 5 GHz band

  C. a signal of -65 dBm in the 5 GHz band

  D. a signal of -75 dBm in the 2.4 GHz band

  Correct Answer: C

• Question 38:

  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?

  A. two QSPF+ BiDi

  B. two QSPF+ MPO

  C. eight SPF+ LR

  D. eight SFP+ SR

  Correct Answer: B

• Question 39:

  An architect needs to plan an 802.11ac wireless upgrade for a university building. What is one reason that it is important for the architect to identify auditoriums?

  A. Auditoriums typically require a high-density AP design for RF coverage.

  B. Users in Auditoriums often have Bluetooth devices, which can be a source of interface in the 5 GHz band.

  C. Auditoriums typically require the use of 80 MHz channels to meet bandwidth requirements.

  D. Auditoriums often require the use of DFS channels for sufficient 20 MHz channels.

  Correct Answer: D

• Question 40:

  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?

  A. a heat map with proposed AP locations and actual tested coverage

  B. a heat map with existing AP locations and actual tested coverage

  C. a heat map with sources of RF interface, both 802.11 and non-802.11

  D. the heat map with proposed AP locations and predictive coverage

  Correct Answer: C
