NEW QUESTION # 76
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 networkinfrastructure 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 has provided floorplans. wall density, and ceiling heights tor the wireless deployment in the carpeted office space What else will be needed to write an accurate bill of material? (Select two)
Answer: A,C
Explanation:
Ceiling construction details are essential for a wireless deployment because the material and structure of the ceiling can affect the propagation of wireless signals. Different materials can absorb or reflect RF signals differently, impacting coverage and signal strength. Understanding ceiling construction helps in planning the placement of access points for optimal coverage and performance. PoE (Power over Ethernet) port details are necessary to ensure that the wired network infrastructure can provide power to the access points and other PoE-enabled devices like VoIP phones and cameras. This information is critical for planning the power budget and ensuring that the network can support the power requirements of all connected devices, ensuring a stable and reliable network infrastructure.
NEW QUESTION # 77
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.
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: B
Explanation:
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.
NEW QUESTION # 78
A customer wants to have the ability to show network usage. Which product would allow them to have this visibility?
Answer: A
Explanation:
* Aruba Central:Aruba Central is the cloud-native management and monitoring platform within the Aruba ESP architecture. It provides:
* Network usage visibility: dashboards and reports on client, application, and device traffic across wired, wireless, and WAN.
* Application visibility and deep packet inspection (DPI): showing how much bandwidth is consumed by each app or category.
* Historical and real-time analytics: enabling IT to monitor utilization trends and demonstrate network usage to stakeholders.
* Why not the other options?
* UXI (User Experience Insight): Provides end-user experience monitoring by using sensor devices to simulate client behavior (e.g., connectivity tests, SaaS performance), but it does not give full network usage visibility in terms of traffic volume or bandwidth utilization.
* ArubaOS 8.x: This is the operating system for Aruba mobility controllers and APs, enabling advanced WLAN features, but not a dedicated platform for traffic visibility dashboards or long- term usage reporting.
* ClearPass: Provides policy-based access control and security (authentication, authorization, accounting, device profiling), but it is not designed to show network traffic usage or utilization statistics.
* Aruba Design Guidance Alignment:According to Aruba's Campus Access Design Guides and Aruba Central documentation, the correct tool for showing and reporting network usage visibility is Aruba Central, which integrates AI Insights, traffic monitoring, and reporting capabilities as part of the ESP cloud platform.
Final Justification:
Option B is correct because only HPE Aruba Networking Central provides the ability to monitor and display network usage visibility in a centralized, graphical, and reportable way.
Reference Extracts (Aruba Official Study & Design Guides):
* Aruba ESP Campus Design Guide: Aruba Central as the management and visibility layer.
* Aruba Central Technical Overview: built-in dashboards for bandwidth utilization, client traffic, and application visibility.
* Aruba Central AI Insights: usage trends and capacity monitoring.

The week after the presentation of your design to the CIO of the cruise line company, the ClO calls you to discuss increasing the 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 have heard about dynamic segmentation and central and decentral overlay networks.
What would you advise as the most cost-efficient solution?
Answer: B
Explanation:
Given the need to increase the security of the wired network infrastructure while being cost- efficient, advising the cruise line company to standardize on Aruba 6300 switches for the access layer is the most appropriate solution. The Aruba 6300 Series offers advanced features suitable for such environments, including high-performance, scalability, and enhanced security capabilities. Adding a cluster of 9240 Gateways for implementing central overlay networks on a User-Based Tunneling (UBT) basis further strengthens the network's security posture. This setup supports dynamic segmentation, which allows for the enforcement of consistent policies and secure access across the network, irrespective of the user or device type. This architecture not only meets the increased security requirements set forth by the cruise line's CSO but also aligns with the company's existing infrastructure and future refresh plans, ensuring cost-efficiency and sustainability.
