HP HPE6-A47 Online Questions & Answers

• Question 21:

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

• Question 22:

  What is one reason to recommend dedicated Air Monitors (AMs) for a customer, as opposed to APs that are doing WIPS in AP mode (hybrid)?

  A. AMs can operate in a hybrid operation mode in which they can support clients, scan for threats, and contain detected threats.
  B. AMs can implement wireless containment on any channel on which they detect a threat without negative impact on clients.
  C. AMs can detect both 802.11 and non-802.11 sources of interference to the wireless network, while APs cannot.
  D. AMs can maintain client and AP blacklists on their own without the need to communicate with a Mobility Controller (MC).
  B. AMs can implement wireless containment on any channel on which they detect a threat without negative impact on clients.

• Question 23:

  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?

  A. The customer can direct all wired traffic through the MCs, which will then apply security to that traffic.
  B. The customer can direct all wired traffic through the MMs, which will impose basic security checks.
  C. ClearPass OnConnect can enable wired authentication on these switches through the use of SNMP.
  D. AirWave can manage these switches and shut down their ports if an unknown user or device connects.
  C. ClearPass OnConnect can enable wired authentication on these switches through the use of SNMP.

• Question 24:

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

• Question 25:

  A customer has a small office building that needs approximately 32 APs. The solution must support basic rogue AP detection and provide a stateful firewall with role-based policies. The customer would like the simplest, most cost-effective deployment that meets their needs.

  What should the architect recommend?

  A. Aruba remote APs
  B. Aruba campus APs and a Virtual Mobility Controller
  C. Aruba Instant APs
  D. Aruba campus APs and an Aruba 7005 Mobility Controller
  D. Aruba campus APs and an Aruba 7005 Mobility Controller

• Question 26:

  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.
  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.

• Question 27:

  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?

  A. The MCs cannot provide any level of redundancy for each other unless one is moved into the other's subnet.
  B. The MCs cannot be in a cluster, and they must use Virtual Router Redundancy Protocol (VRRP) to provide redundancy for each other.
  C. The MCs can be in a cluster, but the cluster will not support features such as stateful failover.
  D. Each MC can be the backup LMS for the other MCs' APs, but it cannot be in a cluster with the other MC.
  B. The MCs cannot be in a cluster, and they must use Virtual Router Redundancy Protocol (VRRP) to provide redundancy for each other.

• Question 28:

  An architect plans 128 APs to support 12,800 devices in a very high density (VHD) design. The customer requires high availability, so the architect plans to recommend a pair of controllers. What is one reason to recommend 7210 controllers rather than 7205 controllers for this deployment?

  A. the need for high speed 10 GbE ports
  B. the need for clustering
  C. the number of devise required
  D. the number of APs required
  C. the number of devise required

• Question 29:

  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
  C. simplification of spanning tree protocol ad the access layer

• Question 30:

  Refer to the exhibit.

  A. 60 Gbps
  B. 160 Gbps
  C. 200 Gbps
  D. 320 Gbps
