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 the security on 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. For their POS systems, they need a low-latency network connection between the POS system and the POS server in the data center on the ship. Also, the CSO wants to enhance the WLAN security as well by tunneling all user traffic.
What solution fits the customer's requirements?
Considering the global cruise line company's requirement to enhance wired network security while ensuring low-latency connections for POS systems and tunneling all user traffic for WLAN security, the most fitting solution involves a combination of Aruba switches and gateway along with a network management and orchestration tool. Specifically, standardizing on Aruba 6300 switches for the edge layer caters to the need for high-performance, fan-less switches with 10GbE uplinks, matching the requirement for upgraded cabin and technical room connections. The Aruba 8320 as a Route Reflector (RR) and Aruba 8360 for the stub/border provide a robust core and distribution layer with high throughput and redundancy. The inclusion of a 9240 WLAN Gateway addresses the need for secure WLAN user traffic tunneling. Utilizing Aruba Central NetConductor enhances network management efficiency, security policy enforcement, and dynamic segmentation across the wired and wireless infrastructure, aligning with the ESP architecture from Aruba and meeting the company's security enhancement objectives.
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 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.)
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.
identify the stakeholders when gathering information for the network design and new IDF/MDF design. (Select two.)
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.
The clients existing network is experiencing trouble with voice occasionally dropping out on phone calls between office locations, it Is determined that no packet loss is occurring and QOS is likely the cause. With what phenomenon Is the client currently experiencing issues?
A)
B)
C)
The client is experiencing issues with Jitter, as depicted in Option B. Jitter refers to the variation in time between packets arriving, caused by network congestion, timing drift, or route changes. In voice communications, jitter can manifest as the occasional dropping out of voice on phone calls because the variable delay can affect the steady stream of voice packets needed for a clear conversation. Even when there is no packet loss, high levels of jitter can significantly impact the quality of Voice over IP (VoIP) calls. Quality of Service (QoS) settings are essential in managing jitter, as they can prioritize voice traffic over other types of data, ensuring that voice packets are delivered consistently and in the correct order to minimize delays and prevent call quality degradation. Aruba Campus Access solutions would typically include QoS features to manage and mitigate jitter on the network.
