An architect proposes an Aruba solution with a hardware Mobility Master (MM) to a customer. The customer has a disaster recovery site which is connected to the main site at Layer 3. The customer requires the MM to remain available in case of a total site failure.
Which plan meets the customer requirements?

Deploy a hardware MM to the disaster recovery site and set up VRRP between them.
Deploy a hardware MM to the disaster recovery site and set its IP address as the standby master for MCs.
Deploy the virtual MM (VMM) to the disaster recovery site and set the VMM IP address to the same address as the hardware MM.
Deploy the virtual MM (VMM) to the disaster recovery site and configure clustering on the hardware and software appliances.

QUESTION: 23

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 tunneled node on Aruba 2930M switch ports that connect to laptops. What is one advantage of this form of authentication?

ensures that Aruba firewall policies apply to wired user traffic.
prevents users from connection attempts with more than three devices
enables user access control and ensures only authorized users connect.
provides a second layer of protection for wireless users at the internal perimeter

QUESTION: 24

Refer to the exhibit.

The exhibit shows the current plan for a wired network upgrade.
As much as possible, the customer wants to flatten the architecture and avoid recabling. However, each Building 2 switch must also maintain connectivity to the core if one link fails. What should the architect propose to meet the customer requirements?

Use two additional 2930F switches to act as an aggregation layer for Building 2; connect them to the core on 40 GbE connections.
Connect each Building 2 switch directly to the core on a single fiber strand through the use of SFP+-SR transceivers.
Combine the switches in each Building 2 closet as a VSF fabric; establish two 10 GbE connections to the core per fabric.
Extend additional fiber between the buildings so that each Building 2 switch can have a direct 10 GbE connection to the core.
