Questions 7

Refer to the exhibit.

The exhibit shows the current plan for a wired network upgrade.

Connect each Building 2 switch directly to the core on a single fiber strand through the use of SFP+-SR transceivers.

C.

Combine the switches in each Building 2 closet as a VSF fabric; establish two 10 GbE connections to the core per fabric.

D.

Extend additional fiber between the buildings so that each Building 2 switch can have a direct 10 GbE connection to the core.

Questions 9

The customer has an office environment with users who have laptops that can connect with wired or wireless. Users also bring one or two of their own devices. An architect creates a proposal with Aruba AP-325s, 7210 Mobility Controllers (MCs), a Mobility Master (MM), and Aruba 2930M switches at the access layer to support the laptops and APs.

The architect plans to recommend 802.1X authentication without tunnelled node on Aruba 2930M switch ports that connect to laptops. What is one advantage of this form of authentication?

Options:

A.

ensures that Aruba firewall policies apply to wired user traffic.

B.

prevents users from connection attempts with more than three devices

C.

enables user access control and ensures only authorized users connect.

D.

provides a second layer of protection for wireless users at the internal perimeter

Questions 10

An architect plans to purpose two Aruba Mobility Controllers (MCs) in a cluster. The customer has a large building that needs to support about 10,000 devices. The architect plans to associate the Employees WLAN with VLAN ID 10.

What is one Aruba best practice for this design?

Options:

A.

Ensure that VLAN 10 is extended to the edge and Aruba APs are deployed on it.

B.

Ensure that each user role on the MCs is associated with a different VLAN ID.

C.

Ensure that the RADIUS server assigns users to different VLANs dynamically.

D.

Ensure that optimization and suppression of unnecessary multicast is enabled.

Questions 11

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?

Options:

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.

Questions 12

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?

Options:

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

Options:

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.
