C)
D)
Answer : C
Based on the requirements provided by 'Don't Buy at Us,' the updated design needs to accommodate 25GbE uplinks and a minimum of 7 stacks of 48-port Aruba switches for the EMEA-DISTR. Option C is the most suitable based on best practices, as it proposes:
A core configuration consisting of two Aruba 8360-12C in VSX for the collapsed core with ISL of 2x100GbE DAC, which will provide robust core networking with high-speed interconnects, suitable for the demands of a regional distribution center and headquarters.
Aggregation with two stacks, each with 2 Aruba 8360-12C in VSX (ISL 2x100GbE DAC), accommodating the uplink capacity requirements.
Access stacks with a total of 17 stacks of Aruba 6300F 48-port 1GbE Class 4 PoE with 4-port SFP56 (each stack has 4 members, VSF with 50GbE VSF links, 2 x 25GbE uplinks per stack), which exceeds the minimum requirement of 7 stacks and provides the necessary uplink bandwidth.
This configuration supports the 25GbE uplink speeds, satisfies the required number of switch stacks for the EMEA distribution center, and is compatible with the existing 25GbE-certified fiber infrastructure at HQ2 and EMEA-DISTR.
Question 2
A global cruise line company needs to refresh its current fleet. They win refresh the insides' of the ship to be cost-effective and increase their sustain ability. They Mill replace the complete WLAN/LAN hardware of the ship. In this refresh, the company will not refresh Us current security requirements. The CIO also wants to limit the number of unused ports in the switches. Future expansion will always mean a refresh of hardware. They start with the smallest ship with a maximum of 800 guests
Each ship has a LAN infrastructure consisting of two core switches, up to 10 redundant distribution switches, and up to 500 access switches (400 cabins. 100 technical rooms). The Core switches are located in the MDF of the ship and the distribution switches are located in the IDFs of the ship. Each cabin and technical room gets one single access switch.
The cabling structure of the ship will not be refreshed. Each IDF is connected to the MDF by SMF. of which two pairs are available for the interconnect between the core and distribution. The length of SM fiber between MDF and IDF is less than 300 meters (930 ft) and the type used is 0S1. Each cabin is connected by a single 0M2 pair to the IDF. the maximum length is 60 meters (200 ft). Each technical room is connected by a single 0M2 pail to the IDF. with lengths between 100 and 150 meters (320 and 500 ft).
For each cabin/technical room the customer is looking to replace their current fan-less 2530/2540 without changing the requirements, except they need to upgrade the uplink to distribution switch to 10GbEto handle the increased network traffic, and the technical rooms need redundant power.
The WLAN infrastructure will be 1:1 refreshed without new cabling or new AP locations. Their WLAN Infrastructure is based on the 200/300 series Indoor and outdoor APs running instantOS (less than 300 APs). the customer has no change in WLAN requirements.
The cruise line company will replace its current Internet connection before the LAN/WLAN refresh. The new Internet connection will provide a 99.8% uptime, which is needed to ensure the paid guest Wi-Fi is always operational. With this new internet connection, the CIO of the cruise line wants to base the design on the ESP architecture from Aruba because Internet connection is guaranteed.
Based on the best practices and customer requirements, what is the correct LAN approach?
Answer : D
In the context of the ESP architecture from Aruba and the specific requirements of the cruise line company, the best practice would be to place management VLANs in the underlay and user VLANs in the overlay. This design allows for a clear separation of management traffic from user data, enhancing security and network performance. The management underlay ensures secure and reliable access to network infrastructure for administrative purposes, while the user overlay allows for flexible and dynamic segmentation of user traffic. This approach is aligned with best practices for network design, where critical management traffic is isolated from user data to prevent unauthorized access and potential security breaches. It also supports the cruise line's need for a robust and secure network to ensure the operational reliability of paid guest Wi-Fi and other critical services.

The week after the presentation of your design to the CIO of the cruise line company, the CIO calls you to discuss increasing trie security of the wired network Infrastructure. Since one of their competitors had one of their cruise ships cyber hacked, the CSO of the cruise line has mandated increased security on the wired network. They nave heard about dynamic segmentation and central and decentral overlay networks.
What would you advise as the most cost-efficient solution?
Answer : C
For a global cruise line company looking to refresh its fleet with a focus on sustainability and cost-effectiveness, while not changing its current security requirements, the most suitable option would be to standardize on Aruba 6300 switches for the access layer. The Aruba 6300 switches offer advanced security features and scalability, which is crucial for the dynamic and demanding environment of a cruise ship. Additionally, implementing a cluster of 9240 Gateways and central overlay networks based on User-Based Tunneling (UBT) will enhance the security of the wired network infrastructure. This approach aligns with the Aruba ESP (Edge Services Platform) architecture, providing a unified infrastructure that integrates security, AI-powered operations, and cloud-native agility. The central overlay networks will enable the cruise line to segment network traffic, apply consistent policies, and provide secure access across the fleet, meeting the increased security demands without compromising on performance or sustainability.
Question 4
identify the stakeholders when gathering information for the network design and new IDF/MDF design. (Select two.)
Answer : A, D
When designing a network and considering new Intermediate Distribution Frame/Main Distribution Frame (IDF/MDF) deployments, it's essential to gather information from various stakeholders to ensure the design meets all operational and organizational requirements. According to Aruba Campus Access learning resources, the Help Desk Manager and Network Operations Manager are crucial stakeholders in this process. The Help Desk Manager provides insights into common issues, user complaints, and service requests, which can influence network design decisions to improve user experience and operational efficiency. The Network Operations Manager, on the other hand, offers a technical perspective on network management, maintenance requirements, and operational challenges. Engaging with these stakeholders ensures that the network design is aligned with both user needs and technical operational standards, contributing to a more resilient, efficient, and user-friendly network infrastructure.
Question 5
What is the best practice for using VSX at the core of a 3-tier design?
Answer : B
In a 3-tier network design consisting of core, aggregation, and access layers, the implementation of Virtual Switching Extension (VSX) at the core is considered a best practice when the aggregation layer functions primarily at Layer 3 with routing protocols like OSPF facilitating traffic forwarding between the core and aggregation layers. This design choice, as verified by Aruba Campus Access documents, leverages the high availability and redundancy features of VSX technology while maintaining efficient and scalable routing at the aggregation layer. Implementing VSX at the core in such a scenario ensures seamless failover and redundancy, minimizing the risk of downtime and ensuring consistent performance across the network. The core layer, equipped with VSX, provides a robust and resilient backbone for the network, facilitating efficient traffic management and routing decisions, which is critical for large-scale enterprise networks.
Question 6
A large multinational financial institution has contracted you to design a new full-stack wired and wireless network for their new 6-story regional office building. The bottom two floors of this facility will be retail space for a large banking branch. The upper floors will be carpeted office space for corporate users, each floor being approximately 100.000 sq ft (9290 sqm). Data centers are all off site and will be out of scope for this project. The customer is underserved by its existing L2-based network infrastructure and would like to take advantage of modern best practices in the new design. The network should be fully resilient and fault-tolerant, with dynamic segmentation at the edge.
The retail space will include public guest Wi-Fi access. Retail associates will have corporate tablets for customer service, and there will be a mix of wired and wireless devices throughout the retail floors. The corporate users will primarily use wireless for connectivity, but several wired clients, printers, and hard VoIP phones will be in use.
The customer is also planning on renovating the corporate office space in order to take advantage of "smart office' technology. These improvements will drive blue-dot wayfinding. presence analytics, and other location-based services
The client decides that they would like for all of their exposed printer, conference room, and VoIP phone
connections to be controlled by a stateful firewall
What could be planned to ensure that these ports will meet the customer's requirements?
Answer : A
To control exposed printer, conference room, and VoIP phone connections with a stateful firewall, utilizing Tunneled Node functionality would be effective. Tunneled Node allows for the encapsulation of wired Ethernet traffic into a user-based tunnel, similar to how wireless traffic is handled. This means that traffic from these devices can be sent through a centralized controller where stateful firewall policies can be applied. This setup ensures that the specific ports used by these devices are subjected to the same level of security scrutiny and policy enforcement as wireless traffic, aligning with the client's requirements for a secure and controlled network environment.

The client decided that wired headless devices would be authenticated using Mac Authentication and would have RADIUS attributes sent back to the NAD to assign VLAN and port access parameters to the authentication session on the switch port.
What would be critical in making this a successful deployment? {Select two.)
Answer : C, D
For a successful deployment of MAC Authentication with RADIUS attributes for VLAN and port access parameters, ClearPass is critical. ClearPass Policy Manager offers advanced network access control, policy management, and is capable of handling MAC Authentication effectively. It can communicate with the Network Access Devices (NADs) to apply the correct access policies based on RADIUS attributes received during the authentication process. DHCP is also crucial in this setup for dynamically assigning IP addresses to authenticated devices, ensuring that they can connect to the network with the appropriate network settings. Together, ClearPass and DHCP services form the backbone of a secure, manageable, and dynamically segmented network infrastructure, ensuring devices are authenticated and receive the correct network configuration.
