HPE6-A49 Online Practice Questions and Answers

Refer to the exhibit.

An architect has planned the wireless and wired access layers for a network upgrade. The entire solution

must support 9,000 wireless devices and 2,250 wired endpoints.

The campus core must meet these requirements:

no more than 4:1 oversubscription on the links to the data center

switch-level redundancy near instant failover if one core switch fails link aggregations between access layer and core same switch software used across the entire campus

Which exhibit shows a campus core that meets the customer needs?

A.

B.

C.

D.

A customer has critical wired endpoints and wants to minimize the chances they will lose their connection

to the network. These endpoints are dual-homed, each with two Ethernet connections that are in a link

aggregation.

The architect plans to deploy two 5406R switches in the closet.

What else should the architect specify in the plan?

A. The 5406R switches are in a VSF fabric; each switch has redundant power supplies, but not redundant management modules.

B. The 5406R switches are not in a VSF fabric; each switch has redundant power supplies but not redundant management modules.

C. The 5406R switches are not in a VSF fabric; each switch has redundant power supplies and redundant management modules.

D. The 5406R switches are in a VSF fabric; each switch has redundant power supplies and redundant management modules.

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.

A customer has Aruba network infrastructure devices that could be managed by either Aruba Central or

Aruba AirWave.

Which customer characteristic should point the architect toward an AirWave recommendation as opposed

to a Central recommendation?

A. desire to lease managed services on an ongoing basis

B. small IT staff and preference for cloud solutions

C. policies that network management occurs on premises

D. need to support Zero Touch Provisioning (ZTP)

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.

Refer to the exhibit.

The network architect has created the BOM shown in the exhibit for a complete new wired and wireless solution for a customer. This solution will support 6000 wireless clients and 900 wired clients. The customer wants to discover and manage every component of the network in AirWave, including MMs, MCs, APs, and switches.

How many AirWave licenses does the architect need to add?

A. 30

B. 222

C. 6930

D. 7122

Compare the scenarios below. For which scenario do AP-365s meet the needs?

A. The customer needs APs mounted to a concrete building exterior to provide coverage in a 90 foot (27m) radius from the building.

B. The customer needs APs for an indoor high density environment in which the customer prefers dual 5GHz operation.

C. The customer needs to mount APs in an outdoor area, but that area only has fiber cable available.

D. The customer needs APs for an indoor stadium that requires overhead coverage and directional antennas.

A school district has instant APs (IAPs) at multiple locations. The school district wants a simpler way to manage the IAPs from a single location. However, it does not have the IT staff to handle the installation

and management of a management solution on site. What should the architect recommend?

A. Purchase a subscription for Aruba Central device management.

B. Deploy Aruba AirWave in central location.

C. Purchase licenses for a Virtual Mobility Controller (VMC).

D. Deploy an Aruba MC in a central location, and convert IAPs to CAPs.

What is one reason that an architect might choose to use pico-cell coverage rather than overhead in a stadium?

A. to avoid major rewiring and construction concerns

B. to save money by using less powerful and less expensive APs in the deployment

C. to support a higher device density with a higher level of channel reuse

D. to maximize coverage per-AP through the use of calculated directional antennas

An indoor sports stadium has 5,000 seats in two rings:

The stadium has a ceiling height of 72 feet (22 m).

There is a catwalk around the perimeter of the stadium that is 54 feet (13 m) from the floor.

There are two scoreboards at either and of the stadium.

The construction of the stadium is concrete and steel.

The customer has indicated a preference for overhead coverage, and the wireless network should support

3500 concurrent clients. The architect plans to install the APs on the catwalk to service sections of the floor

below.

Which type of antennas are recommended for the APs that provide the overhead coverage?

A. high gain directional

B. high gain omnidirectional

C. downtilt

D. Yagi
