C.   responsible for authoring the low-level design and creating the configuration to meet the technical requirements

Answer DescriptionExplanation: The role of the Network Designer/Architect in a large-scale network infrastructure project is to develop a detailed technical design that meets the project's requirements. This involves authoring the low-level design documents, which include detailed network diagrams, device configurations, and implementation guidelines. The Network Designer/Architect must understand the technical specifications and business goals to create a solution that is not only technically sound but also aligned with the organization's objectives. This role is critical inensuring that the network infrastructure is designed to be scalable, reliable, and secure, providing a solid foundation for the organization's operations.

A.   Aruba SO-Branch Architecture

Answer DescriptionExplanation: For ACME Retail, which aims to host all applications at the HO Data Center and has multiple locations spread across different geographical areas, the Aruba SD-Branch Architecture would be the most suitable design to meet their requirements. This architecture provides a simplified, integrated branch networking solution combining SD-WAN, LAN, and security features. It enables centralized management and control, allowing ACME Retail to efficiently route traffic from branch locations to the HO Data Center, ensuring secure and reliable access toapplications. The SD-Branch solution can accommodate the company's growth and adapt to changing network demands, making it an ideal choice for a scalable and flexible network infrastructure that supports ACME Retail's business objectives.

A.   6400 with Aruba CX Advanced License

Answer DescriptionExplanation: Aruba OS-CX switches, specifically the Aruba 6400 and 6300F/M models, are designed to support advanced networking features, including Application Recognition, with the Aruba CX Advanced License. The Advanced License enables enhanced capabilities such as deeper visibility into application flows, advanced routing features, and improved network analytics. Application Recognition allows these switches to identify and classify applications running on the network, enabling more intelligent and dynamic network policies and improving overall network performance and security. The requirement for an Aruba CX Advanced License on these specific models ensures that the necessary software features and support are available to leverage Application Recognition capabilities effectively.

A.   A1000Base-LX Transceiver is operated with 62.5/125 cables up to 500 m.

Answer DescriptionExplanation: Mode Conditioning Patch Cables (MCPs) are used in situations where long wavelength laser transceivers, such as the 1000Base-LX, are deployed over multimode fiber types like the 62.5/125 µm. The 1000Base-LX transceivers are designed primarily for use with single-mode fiber, but they can operate over multimode fiber using an MCP. The MCP is necessary because the core size of multimode fiber (62.5/125 µm) is significantly larger than that of single-mode fiber, which can lead to modal dispersion when a single-mode laser signal enters the multimode fiber. This dispersion can degrade the signal quality over longer distances. The MCP mitigates this issue by aligning the single-mode laser output from the transceiver to a specific launch point in the multimode fiber, thus minimizing dispersion and allowing for effective data transmission over distances up to 500 meters.

D.   tire escape plan

Answer DescriptionExplanation: When floor plans are not available for site surveys or simulations, the best alternative source to use is the fire escape plan (Option D). Fire escape plans are typically available in most buildings and provide a simplified layout of the premises, including walls, doors, and sometimes the location of permanent fixtures. While not as detailed as architectural floor plans, fire escape plans can offer enough information for initial site survey estimations and RF planning. They allow network designers to understand the basic layout and potential RF obstacles or coverage areas, making them a practical tool for preliminary wireless network planning and simulations in the absence of more detailed floor plans.

B.   SFP56 transceivers


D.   SFP28 transceivers

Answer DescriptionExplanation: To meet the customer's requirement of managing two wiring closets as a single stack with a minimum transport speed of 25Gbps over OM4 MM fiber, especially when the closets are 190m apart, the most cost-effective solution would involve using SFP transceivers. SFP28 transceivers can support speeds up to 25Gbps, aligning with the customer's minimum speed requirement. For higher speeds or future-proofing, SFP56 transceivers, which can support speeds up to 50Gbps, could also be considered. Both types are compatible with OM4 multimode fiber, which is capable of supporting these high speeds over the distance specified. DAC (Direct Attach Cable) solutions like options A and C would not be feasible due to the 190m distance between the closets, as DAC cables are typically used for much shorter distances.

C.   Standardize on Aruba 6300 switches for the access layer, add a cluster of 9240 GWs. and Implement central overlay networks on UBT basis.

Answer DescriptionExplanation: 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.

B.   beacons


C.   more APs

Answer DescriptionExplanation: For improving Blue Dot location tracking in corporate spaces where access points (APs) are not ideally placed for smooth map transitions, adding more APs and deploying beacons are effective strategies. More APs can enhance the density and coverage of the Wi-Fi network, providing more data points for more accurate location tracking. Beacons, specifically designed for precise indoor positioning, can supplement Wi-Fi-based location services by broadcasting signals that mobile devices can use to determine their location with greater accuracy. This combination ensures better tracking and smoother map transitions within the corporate space, enhancing the overall effectiveness of the Blue Dot location tracking solution.
