An architect proposes four 7210 Mobility Controllers (MCs) to support about 1,500 client APs. The customer environment will have a maximum of about 20,000 wireless clients. The customer wants hardware MMs with an active and standby deployment.

What is the minimum solution that meets the customer requirements?

A. two MM-HW-10K appliances

B. two MM-HW-5K appliances

C. four MM HW-5K appliances

D. four MM HW-10K appliances

A customer needs a solution to terminate VPN tunnels for Aruba RAPs. The customer has a single site and a single public IP address for this purpose. Network address translation (NAT) will forward the IPsec traffic to the correct device to terminate the VPN tunnel. The customer also requires N+1 redundancy for the solution.

Which solution meets the customer requirements?

A. two Aruba MCs on the same subnet that use VRRP without clustering

B. two Aruba MCs deployed as a Layer 3 cluster

C. two Aruba MCs on different subnets that use VRRP without clustering

D. two Aruba MCs deployed as a Layer 2 cluster

An RF plan specifies wide sector directional antennas.

Refer to the antenna specifications.

H-plane refers to the Azimuth or Horizontal plane and E-plane refers to Elevation or Vertical plane.

Antenna 1: H-plane = 360; E-plane = 120

Antenna 2: H-plane = 360; E-plane = 60

Antenna 3: H-plane = 100; E-plane = 90

Antenna 4: H-plane = 60; E-plane = 60

Which antenna specifications indicate that the antenna is a good choice for the plan?

A. Antenna 1

B. Antenna 2

C. Antenna 3

D. Antenna 4

A plan includes these security settings for the employee WLAN:

1.

WPA2-Enterprise with AES encryption

2.

802.1X with PEAP-MSCHAPv2

However, the customer wants to use certificates to authenticate user devices.

Which change brings the plan in alignment with the customer requirements?

A. Use EAP-TLS instead of PEAP-MSCHAPv2

B. The TKIP encryption instead of AES.

C. Add WPA2-PSK as an alternative to WPA2-Enterprise.

D. Add Tunneled TLS (TTLS) as an alternative to PEAP-MSCHAPv2.

An architect plans where to deploy new Aruba 320 Series APs at a customer site. The architect plans for the APs to be installed on the ceiling where power is inaccessible. The Ethernet cable run to these locations is CAT6, and the customer wants to support at least 1 GbE connectivity. The architect plans to connect each AP with one Ethernet port to a switch in a nearby wiring closet.

Which feature does the switch need to support for this deployment?

A. PoE+

B. LACP

C. Port channel

D. Smart Rate

A customer needs a wired network solution that can recognize and prioritize a wide array of different types of traffic, including casual Web browsing, voice, video, SAP Online, and file sharing.

The architect needs to choose between the Aruba 2930F or the 2540 Switch Series for the access layer switch.

Why would the architect choose the 2930F rather than the 2540 Switch Series for this customer?

A. The 2930F Series supports LLDP-MED for detecting VoIP traffic, while the 2540 Series does not.

B. The 2930F Series supports advancing routing, including multi-area OSPF, while the 2540 Series does not.

C. The 2930F Series supports more options for class-based QoS policies that the 2540 Series.

D. The 2930F Series can provide better congestion management with its much deeper buffers.

For which scenario does the Aruba backplane stacking technology meet the needs?

A. The customer needs to deploy a pair of aggregation switches in the same closet, and wants to simplify the architecture and redundancy design.

B. The customer needs to simplify the deployment of core switches which are located in different closets for redundancy purposes.

C. The customer needs to expand the network and make it possible for the current core switches to support more MAC forwarding and ARP entries.

D. The customer needs to deploy a switch at a branch office and have the switch automatically discover and join the network stack at the main office.

Refer to the exhibit.

A customer needs to upgrade the wireless network at their campus, which has a single large building. Employees use the wireless network to access the Internet and centralized services. The building has four floors. These are the requirements: 30 APs on each floor A Mobility Master (MM)-based architecture Deployment of one Aruba 7030 Mobility Controller (MC) on each floor, with the MCs combined in a cluster for seamless client failover and roaming

What should the architect explain to the customer about the proposed solution?

A. MCs should be deployed centrally on the same VLAN to better meet these goals

B. MCs in a cluster must have additional AP licenses to support APs of a failed controller

C. The MC 7030 does not support enough APs for the requirements

D. The MC 7030 only supports clusters with up to three members

An architect simulates VoIP calls and tests the throughput as 67 Kbps, packet loss as 0.3 percent, maximum latency as 100 ms, and maximum jitter as 100 ms.

Which issue typically causes a poor experience for users?

A. the packet loss

B. the throughput

C. the latency

D. the jitter
