Answer: C
An architect plans 12 APs for an auditorium that is 325 square meters (3, 498 square feet). Each AP has one 2.4 GHz radio and one 5 GHz radio. Both types of radios use 20 MHz channels.
Assume that DFS channels can be used in this design.
How many 5 GHz collision domains does this design provide?
A . 1
B . 6
C . 12
D . 25

Answer: B
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?
A . Deploy a hardware MM to the disaster recovery site and set up VRRP between them.
B . Deploy a hardware MM to the disaster recovery site and set its IP address as the standby master for MCs.
C . Deploy the virtual MM (VMM) to the disaster recovery site and set the VMM IP address to the same address as the hardware M
E . Deploy the virtual MM (VMM) to the disaster recovery site and configure clustering on the hardware and software appliances.
Answer: A
Aruba AirWare
The architect also needs to propose a security plan for the solution. The customer has 900 employees and up to 30 guests a day. The customer wants to protect the internal perimeter of the network with authentication and simple access controls. The customer is most concerned about wireless security, but also wants to ensure that only trusted users connect on the wire.
However, the customer also wants all wired traffic to be forwarded locally on access layer switches. The customer already has a third-party firewall that protects the data center.
The customer wants to use certificates to authenticate user devices, but is concerned about the complexity of deploying the solution. The architect should recommend a way to simplify. For the most part users connect company-issued laptops to the network.
However, users can bring their own devices and connect them to the network. The customer does not know how many devices each user will connect, but expects about two or three per-user. DHCP logs indicate that the network supports a maximum of 2800 devices.
Refer to the provided scenario.
Which solution should the architect recommend on the 2930M switches to authenticate and control wired employee devices?
A . MAC-Auth on edge ports and no tunneled node
B . 802.1X on edge ports and per-user tunneled node
C . 802.1X on edge ports and no tunneled node
D . Mac-Auth on edge ports and per-user tunneled node
Answer: A
An architect learns that a customer site is 14,307 square meters (154,000 square feet) and supports 900 employees using WiFi 5 Ghz radio.
What additional information should the architect collect to create the RF plan?
A . number of devices used
B . the OS used on wireless devices
C . whether BLE wayfinding is required
D . software version on Mobility Controllers (MCs)

Refer to the provided scenario. Based on the plan for wired authentication, what is a correct plan for wired user VLANs?
A . use the MCs to assign wired users to their VLANs, and extend the VLANs to a Layer 3 switch connected to the MC
B . specify the VLANs in network policies on AirWare, and ensure that both the switches and MCs are managed by AirWare
C . assign wired users to different VLANs from wireless users, based on port or role assignments on access layer switches. Extend the VLANs to the core.
D . configure the same roles on switches and MCs to place wired and wireless users in the same VLANs. Extend VLANs from access layer switches to the core.
Answer: C
Refer to the exhibit.
The customer needs to expand its wired and wireless network to a new building, Building 2, which is near the existing building, Building 1. The exhibit shows the logical plan that the architect has created so far. The aggregation layer switches in the new building should provide the default gateway services for the VLANs in the new building and route traffic to the core. The existing Aruba Mobility Controllers (MCs) will control the new APs.
What should be the VLAN assignment for Link 1, indicated in the exhibit?
A . an unused VLAN such as 200
B . VLANs 21, 22, and 23 only
C . VLANs 11, 12, 13, 21, 22, and 23
D . the default VLAN and VLAN 14
Answer: C
Refer to the exhibit.
Exhibit 1 shows the logical plan, and Exhibit 2 shows the BOM created with IRIS. An architect plans to propose two 5406Rzl switches as a VSF fabric for a campus network core.
Which issue with the plan should the architect correct?
A . Add two QSPF+ MP0 SR4 transceivers.
B . Change the v2 modules to v3 modules.
C . Add stacking modules and cables.
D . Change the power supply type.
Answer: B
Which guidelines should an architect use to determine how many AirWave servers to recommend?
A . One server should be deployed on every subnet with an infrastructure device.
B . One server is recommended for the base features and one server each for add-on features such as Clarity.
C . One server should be dedicated to the wired infrastructure and one server to the wireless infrastructure.
D . One server should monitor and manage up to about 4,000 infrastructure devices.
