Aruba Certified Design Expert 8 Written Exam: HPE6-A49

A customer has multiple medium and large branch sites, each of which requires between 8 and 16 APs and supports between 200 and 600 wireless clients. Every branch site has an internet connection, which it uses to reach the central data center. The customer would prefer the WAN links to be optimized in the solution. Each side handles between 1 and 2 Gbps of traffic, most of which goes to the central data center. The data center has 7210 controllers for terminating the VPN connections.

Which branch office solution best meets the customer needs?

A. CAPs and branch office controllers with an SD-WAN license

B. IAPs and no branch office controllers

C. CAPs and branch office controllers

D. RAPs and no branch office controllers

Refer to the exhibit.

A customer has a wired infrastructure shown in the exhibit. The customer is in the process of expanding

their wireless services. They will now add a new wireless solution, with mobility controllers (MCs)

connected as shown. The new wireless solution will support a total of 450 APs and about 26,000 wireless

devices. It must provide seamless roaming across the entire campus.

After the new deployment, both wired and wireless devices experience IP connectivity issues.

Which change to the existing infrastructure should the architect recommend to support all of the customer

requirements?

A. The MCs should be moved to the aggregation layer, and more MCs added.

B. The core and aggregation switches should disable Virtual Switching Framework (VSF).

C. The core switches should be replaced with switches that have larger ARP tables.

D. The wired VLANs should be combined into a single VLAN and /16 subnet.

Refer to the exhibit.

A museum wants to add full 802.11ac wireless coverage across the building, which is about 210 feet (64 m) by 330 feet (100m). The museum has 15-foot (4,6 m) ceilings and stone interior walls. The network needs to support up to 600 wireless guest devices. The exhibit also shows a preliminary plan for AP locations. The museum has eight Ethernet drops in the lobby and gift shop, but has otherwise not been wired.

What is one recommendation that the architect should make to ensure a successful deployment?

A. use of directional antennas to avoid lost signal

B. addition of a writing closet closer to the north side

C. use of at least CAT5 cable to connect to the APs

D. addition of about 10 APs to achieve adequate density
