HP HP Certifications HPE6-A49 Questions & Answers

• Question 31:

  Refer to the exhibit.

  

  The customer requires a solution for the writing closet shown in the exhibit. The closet serves the entire floor, which is wired for CAT5e cable. The closet has four CAT5e cables to the data center 110 feet (34 m) away. The switch or switches in this closet will need to support 100 wired endpoints and 16 AP-345s. The switch or switches must connect to the network core, Aruba 5406R switches, in the data center on uplinks that provide at least 20 Gbps bandwidth total.

  What is one benefit of an Aruba solution for meeting these requirements?

  A. AOS-Switches can meet the uplink bandwidth needs with an extensive array of choices for transceivers.

  B. Aruba PoE+ ports can provide more than 30W of power even to APs at the fat end of the floor.

  C. Aruba Smart Rate ports enable switches to achieve the required uplink speeds without expensive re-cabling.

  D. Aruba conditioning mode cables enable 10GbE SFP+ of 40GbE QSFP+ connections on copper cabling.

  Correct Answer: B

• Question 32:

  Refer to the exhibit.

  

  An architect needs to design the topology for a new wired network at a campus with three buildings. The exhibit above shows the cabling layout. The customer requires link redundancy at all layers, up to one switch-to-switch link can fail without an effect on client connectivity. The architect has determined that the closet of each floor should have three Aruba 2930M switches, and the core will use Aruba 5406 switches. The aggregation layer, if used, will use Aruba 3810M switches. However, the customer prefers the elimination of the aggregation layer and has asked the architect to advise the impact of the elimination of this layer.

  Where would the elimination of the aggregation layer require rewriting?

  A. All of the buildings

  B. Building 1 and Building 2 only

  C. Building 1 and Building 3 only

  D. Building 3 only

  Correct Answer: C

• Question 33:

  Refer to the exhibit.

  

  A company needs a new wireless solution for its large campus with multiple buildings. The campus has 8,000 users, and the company also has 1000 users who use VIA concurrently. The customer requires full redundancy for the Mobility Controllers (MC), including seamless roaming and stateful failover for the main site. Buildings are close enough together for users to roam between them. The exhibit shows the existing wired network. The architect plans to propose: 500 APs (100 each in Building 1 and 2, 200 each in Buildings 3 and 4). two 7030 MCs two 7220 MCs one MM appliance

  The exhibit shows the existing wired network at the main site.

  Where should the architect plan to connect the MCs? (Potential locations are numbered in the exhibit.)

  A. two 7030 MCs at 6; two 7220 MCs at 5

  B. one 7030 MC at 1 and one at 2; one 7220MC at 3 and one at 4

  C. two 7030 MCs at 5; one 7220 MC at 3 and one at 4

  D. all of the MCs at 6

  Correct Answer: A

• Question 34:

  A hospital needs an upgrade to 802.11ac for its wireless network, which needs to provide complete coverage. The hospital has a concrete exterior and uses drywalls for all of the interior walls with a few exceptions as mandated for safety. The building has 10 foot (3m) ceilings. The legacy APs were deployed in the hallway, but the customer is open to deploying APs in any room such as reception areas, patient rooms, operating rooms, treatment rooms, and lounges. The wireless network must support wireless medical devices, voice communicators for medical staff, laptops in nurse stations, medical staff tablets, and visitor and patient personal devices. All of these devices support both the 2.4GHz and 5GHz band. The exhibits below show one wing of one floor of the hospital. This wing is about 14,000 square feet (1300 sq. m). This area has up to: 40 concurrent patients and visitors, who might have up to two devices 40 concurrent staff members, who might have up to three devices About 100 medical and other types of wireless devices

  Several of these wireless medical devices are in the X-ray and X-ray control rooms. The architect has already planned to place APs in stairwells on another floor.

  Which AP plan for this wing of this floor meets the customer needs?

  A.

  

  B.

  

  C.

  

  D.

  

  Correct Answer: D

• Question 35:

  In which scenario do Aruba 5400R Series switches, but not Aruba 2930M Series switches, meet the needs for a wired upgrade?

  A. The customer has recently deployed Aruba AP-345 APs and is concerned about a future-proof wired edge that will continue to support expanding bandwidth requirements.

  B. The customer requires each access layer switch to support at least 40Gbps on its fiber uplinks at all times, including if up to one uplink fails.

  C. The customer requires enhanced redundancy at the access layer and wants to ensure that each switch can continue to operate even is a power supply fails.

  D. The customer requires switches in the same closet to connect together into a single virtual switch that is managed and operates as a single device.

  Correct Answer: B

• Question 36:

  A company currently has 45 IAP-315 at a remote site. These IAPs connect to the main office on a WAN link and use an IPsec VPN to an MC. The company has determined that it needs better optimization and higher VPN throughput for traffic sent to the main office.

  What should the network architect propose to fill this gap?

  A. a subscription to Aruba Central services for WAN optimization

  B. the deployment of several additional IAP-315 to boost throughput

  C. the deployment of a local MC at the remote site

  D. the purchase of SD-WAN licenses for the remote site IAPs

  Correct Answer: D

• Question 37:

  Refer to the exhibit.

  

  A customer has these availability requirements: loss of one controller with stateful failover and without impact on wireless client connectivity loss of one core switch without loss of connectivity for any endpoints or APs in the building loss of any one switch-to-switch or MC-to-switch link without loss of connectivity for any endpoints or APs in the building and with minimal impact on infrastructure functionality loss of any one access switch with minimal impact to wireless client connectivity

  The exhibit shows the current plan for the topology.

  Which change should the architect make to the plan to provide better support for the customer availability requirements?

  A. Use two 40GbE DACs for the VSF link between the core switches.

  B. Add VLANs 11 and 15 to the MC connections to ensure both MCs can manage any of the APs.

  C. Add 120 additional AP licenses, so that each MC can support all the APs even if the other MC fails.

  D. Change the 40GbE DAC on the 5406R switch to a stacking cable with stacking module.

  Correct Answer: D

• Question 38:

  A university has a dormitory with several floors. Currently, APs are deployed in the hallways about every

  50 feet (15 m). The university has several issues with the existing network:

  Students complain that the wireless network is very slow, and IT staff have observed a low signal in the

  student rooms.

  Students want to connect some equipment, such as gaming consoles and IP TVs, on Ethernet, but the

  dorm rooms just have one Ethernet port.

  What could the architect plan to resolve all of these pain points?

  A. Deploy an AP 335 inside each dorm room.

  B. Keep the existing APs, but add more in the hallways to increase signal strength.

  C. Replace the existing APs with AP 345s and add more Ethernet ports to each room.

  D. Deploy an AP 303H inside each dorm room.

  Correct Answer: D

• Question 39:

  Refer to the exhibit.

  

  A writing closet needs to support these devices: 100 desktops 5 printers 20 AP-345s

  The customer wants to single-home the AP-345s and support higher than 1GbE speeds on the AP connections to future proof. The customer also requires that the closet have two 10GbE links to the core with SR transceivers. The exhibit shows the preliminary plan for this closet.

  Which correction should the architect make to the plan to meet the customer requirements?
