An architect needs to plan a wireless deployment. The architect conducts a physical walkthrough, but still needs more information.

Which significant RF obstacle can be difficult to see visually and might require access to blueprints?

A. fiberglass

B. metal firewall

C. ceiling tiles

D. drywall

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.

An architect proposes an Aruba wireless solution for a customer that uses Microsoft Skype for Business. What should be set up on the MCs, or MM, to ensure that wireless voice traffic is properly prioritized?

A. Firewall policies and SDN to mark voice

B. Broadcast suppression combined with AirGroup

C. Airtime Fairness set to fair-access

D. Voice-aware Layer 3 roaming

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.

What is a key criteria that an architect should use to choose between an Aruba 7000 Series or 7200 Series Mobility Controller (MC)?

A. the number of wireless devices that the MC needs to support

B. whether the MC needs to terminate VPN tunnels

C. the need to deploy controllers in a cluster

D. whether the MC needs to support advanced 8.x features
