NEW QUESTION # 25
Refer to the exhibit.
Exhibit 1.
Exhibit 2.
Exhibit 1 shows the logical plan, and Exhibit 2 shows the BOM that the administrator has made in Iris. What is missing from the IRIS BOM?
- A. an uplink module for one of the switches
- B. 10 GbE direct attach cables
- C. stacking licenses
- D. stacking modules and cables
Answer: D
Explanation:
The IRIS BOM is missing stacking modules and cables for the Aruba 2930M switches. The customer wants to flatten the architecture and avoid recabling, but also maintain connectivity to the core if one link fails. To achieve this, the architect proposed to combine the switches in each Building 2 closet as a VSF fabric and establish two 10 GbE connections to the core per fabric. However, to create a VSF fabric, the switches need to have stacking modules and cables to interconnect them. The IRIS BOM does not include these items, which are required for the VSF configuration. The part numbers for the stacking modules and cables are JL325A and J9735A, respectively.
The other options are not missing from the IRIS BOM because they are either not required or already included.
Stacking licenses are not required for the Aruba 2930M switches, as they support VSF natively. 10 GbE direct attach cables are already included in the IRIS BOM as part number J9283D. An uplink module for one of the switches is not required, as the customer already has enough fiber strands to connect each switch to the core.

NEW QUESTION # 29
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. Which ClearPass licenses should the architect include in the proposal?
- A. 1,000 Access licenses and 1000 Onboard licenses
- B. 3,000 Access licenses and 3,000 (3x1000) Onboard licenses
- C. 1,000 Access licenses and 3,000 (3x1000) Onboard licenses
- D. 3,000 Access licenses (3x1000) and 1000 Onboard licenses
Answer: D
Explanation:
ClearPass Access licenses are required for each unique endpoint that authenticates to ClearPass using any supported protocol, such as 802.1X, MAC authentication, web authentication, or VPN authentication1. ClearPass Onboard licenses are required for each unique endpoint that is provisioned with a certificate using the ClearPass Onboard service2. In this scenario, the customer has 900 employees and up to
30 guests a day, which means there are at most 930 users who need to authenticate to the network. Assuming each user has about two or three devices, the maximum number of devices that need Access licenses is 930 x 3
= 2790, which can be rounded up to 3000. The customer also wants to use certificates to authenticate user devices, which means they need Onboard licenses as well. However, the customer only issues laptops to the employees, which means only 900 devices need Onboard licenses. Therefore, the architect should include
3000 Access licenses and 1000 Onboard licenses in the proposal. References:

NEW QUESTION # 30
Refer to the exhibit.
An architect selects 5406R switches for the aggregation layer. What is an appropriate amount of bandwidth for the link aggregation between each aggregation layer VSF fabric and the campus core?
- A. 160 Gbps
- B. 200 Gbps
- C. 60 Gbps
- D. 320 Gbps
Answer: B
NEW QUESTION # 31
A customer has a small office building that needs approximately 32 APs. The solution must support basic rogue AP detection and provide a stateful firewall with role-based policies. The customer would like the simplest, most cost-effective deployment that meets their needs.
What should the architect recommend?
- A. Aruba Instant APs
- B. Aruba campus APs and an Aruba 7005 Mobility Controller
- C. Aruba campus APs and a Virtual Mobility Controller
- D. Aruba remote APs
Answer: A
Explanation:
Aruba Instant APs are a simple, easy to deploy, and cost-effective solution for small office buildings that need wireless access. Aruba Instant APs can form a self-organizing and self-healing mesh network that supports basic rogue AP detection and provides a stateful firewall with role-based policies. Aruba Instant APs do not require a separate controller or license, and can be managed from the cloud or a mobile app. Aruba remote APs are designed for branch or home offices that need to connect to a central controller over a WAN link.
Aruba campus APs and a Virtual Mobility Controller are suitable for larger or more complex deployments that need more scalability and flexibility. Aruba campus APs and an Aruba 7005 Mobility Controller are also more expensive and require additional hardware and licensing.

NEW QUESTION # 34
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 different subnets that use VRRP without clustering
- B. two Aruba MCs on the same subnet that use VRRP without clustering
- C. two Aruba MCs deployed as a Layer 2 cluster
- D. two Aruba MCs deployed as a Layer 3 cluster
Answer: B
Explanation:
The customer needs a solution that can terminate VPN tunnels for Aruba RAPs, which are remote access points that connect to the corporate network over the Internet. The customer has only one public IP address, which means that they need to use NAT to forward the IPsec traffic to the device that will terminate the VPN tunnel. The customer also wants N+1 redundancy, which means that they need at least two devices that can act as backup for each other in case of failure.
The solution that meets the customer requirements is to use two Aruba MCs on the same subnet that use VRRP without clustering. VRRP stands for Virtual Router Redundancy Protocol, and it is a protocol that allows multiple devices to share a virtual IP address and act as a single gateway for the network. This way, the customer can use the virtual IP address as the public IP address for the NAT, and the IPsec traffic will be forwarded to the device that is the VRRP master. If the master device fails, the backup device will take over the role of the master and continue to terminate the VPN tunnels. This provides N+1 redundancy for the customer.
The other options are not suitable for the customer requirements:
Option B is not suitable because a Layer 3 cluster requires two public IP addresses, one for each MC.
The customer only has one public IP address, so they cannot use this option.
Option C is not suitable because VRRP does not work across different subnets. The customer needs to have the MCs on the same subnet to use VRRP.
Option D is not suitable because a Layer 2 cluster does not support NAT. The customer needs to use NAT to forward the IPsec traffic to the MCs.
