NEW QUESTION # 35
Refer to the exhibit.
A customer wants to replace the core and aggregation layer of an existing network. Currently the network routes between the aggregation layer and core, and uses the technologies shown in the exhibit.
The customer now wants to route at the core, instead of the aggregation layer, and extend some of the same VLANs in different buildings. However, the customer cannot eliminate the aggregation layer at this point. What should the architect recommend?
- A. Combine all switches in the aggregation layer and core into a single backplane stack.
- B. Use VRRP on the core and aggregation switches, with the aggregation switches acting as standby.
- C. Create a backplane stack at the aggregation layer and a VSF fabric at the core.
- D. Implement broadcast filtering on switch-to-switch links across all of the buildings.
Answer: A
NEW QUESTION # 36
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 the virtual MM (VMM) to the disaster recovery site and set the VMM IP address to the same address as the hardware MM.
- B. Deploy a hardware MM to the disaster recovery site and set its IP address as the standby master for MCs.
- C. Deploy a hardware MM to the disaster recovery site and set up VRRP between them.
- D. Deploy the virtual MM (VMM) to the disaster recovery site and configure clustering on the hardware and software appliances.
Answer: B
Explanation:
In the event of an MM outage, MCs continue to use their existing licenses for 30 days, and the network remains up. However, you cannot change the configuration items in the controller network. In addition, the MM manages many of the higher level functions that can cause issues in the network if the MM fails. Aruba recommends a backup MM for these situations. From an economic point of view, a backup MM for a VMM is free. If a customer has a hardware MM, the customer must purchase a backup hardware MM.

- D. the latency
Answer: C
NEW QUESTION # 38
Read this scenario thoroughly, and then answer each question that displays on the right side of the screen.
An architect proposes these products for a customer who wants a wireless and wired upgrade:
Aruba 2930M switches at the access layer
Aruba 5406R switches at the core
Aruba AP-325s
Aruba 7205 Mobility Controllers (MCs), deployed in a cluster
Aruba Mobility Master (MM)
Aruba ClearPass Cx000V
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. 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:
Explanation:
C
Explanation:
This answer is correct because it meets the customer's requirements for wired authentication and traffic forwarding. By assigning wired users to different VLANs from wireless users, the architect can ensure that the wired traffic is not tunneled to the MCs, but forwarded locally on the access layer switches. This reduces the load on the MCs and the network bandwidth. By using port or role assignments on the access layer switches, the architect can also implement 802.1X authentication without tunnelled node, which enables user access control and dynamic VLAN assignment based on user identity and device type. By extending the VLANs to the core, the architect can ensure that the wired users can reach the data center and other network resources through the Layer 3 switch connected to the firewall.

* Mobility Controller (MC) 7210s
* Virtual Mobility Masters (MMs)
* ClearPass
* AirWave
The customer is interested in wired authentication, as well as wireless authentication, but does not have the budget to upgrade the wired network. The wired network does not currently support 802.1X or RADIUS.

Answer: A
NEW QUESTION # 40
An architect plans 128 APs to support 12,800 devices in a very high density (VHD) design. The customer requires high availability, so the architect plans to recommend a pair of controllers. What is one reason to recommend 7210 controllers rather than 7205 controllers for this deployment?
- A. the need for high speed 10 GbE ports
- B. the need for clustering
- C. the number of APs required
- D. the number of devise required
Answer: D

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

Which benefit of this feature should the architect explain?
- A. Clustering provides wireless client load balancing and seamless failover for client sessions.
- B. Clustering enables an AP with a failed MC to reconnect to a new AP after a short bootstrap.
- C. Clustering provides high stability because one MC is active for all sessions and one is standby for all sessions.
- D. Clustering enables an AP with a failed MC to operate on its own briefly to ensure seamless connectivity.

NEW QUESTION # 51
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 by each user
- B. the OS used on wireless devices
- C. whether BLE wayfinding is required
- D. software version on Mobility Controllers (MCs)
Answer: A
Explanation:
The number of devices used by each user is an important factor for creating the RF plan, as it affects the network capacity, bandwidth demand, and interference level. The architect should estimate the average number of devices per user and the types of applications they use, such as voice, video, or data. This will help the architect to determine the optimal number and placement of access points, the channel width and selection, the transmit power and data rates, and the radio resource management settings.
The OS used on wireless devices, whether BLE wayfinding is required, and the software version on MCs are not directly relevant for creating the RF plan, as they do not affectthe physical layer characteristics of the wireless network. However, they may have implications for other aspects of the network design, such as security, compatibility, and features.
