NEW QUESTION # 69
A global cruise line company needs to refresh its current fleet. They will refresh the 'insides' of the ship to be cost-effective and increase their sustainability. They will replace the complete WLAN/LAN hardware of the ship. In this refresh, the company will not refresh its 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 (980 ft) and the type used is OS1. Each cabin is connected by a single OM2 pair to the IDF, the maximum length is 60 meters (200 ft). Each technical room is connected by a single OM2 pair 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 10GbE to 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 quest 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: A
Explanation:
Underlay Network: This approach is ideal for maintaining simplicity and efficiency in a ship's network environment, where there is a clear need for robust connectivity for both management and user traffic. By keeping both types of VLANs in the underlay, the network can ensure better performance and easier troubleshooting. The underlay provides the foundational connectivity, which is crucial for handling the expected increase in network traffic due to the upgrade.
Overlay Networks: While overlay networks can provide flexibility and segmentation, they are generally more complex and may not be necessary in this scenario, especially given the focus on cost-effectiveness and the existing cabling structure.
NEW QUESTION # 70
XYZ Regional Hospital is an integrated healthcare system of hospitals, neighborhood health centers, and small doctor offices. XYZ Regional Hospital has recently merged with 4x neighborhood health centers and
125 doctor branch offices. The wireless, wired access, and AAA
solutions are outdated and need to be replaced
XYZ Regional Hospital is looking to future-proof and improve efficiency across all sites by enhancing wired and wireless access and migrating to a centralized and unified wired/wireless and policy management that can provide uninterrupted availability of all systems.
Locations:
- XYZ Regional Hospital is located in New York City
- Dila Health Center is located in City A
- Mount Health Center is located in City B
- Rock Health Center is located in City C
- Branch clinics are located at different locations across the United States Requirements:
- Provide, via management software, one single pane of glass to manage wired and wireless IANs. and VPNs across campus, branch, and remote via web/cloud architecture providing near real-time Insight.
troubleshooting tools, and Service Level performance reporting.
- Seamless integration across wired, wireless. WAN. SD-Branch. loT
- Provide secure wireless access to all the employees of the Regional Hospital and partners, as well as provide wireless Internet access to medical citizens when they visit our facilities.
- All-access points must support the following features and specifications: 802.11ax (Wi-Fi 6E Certified)
- Security options including WP2/WPA3. 802.1X with Radius secure authentication
- Identify and authenticate every wireless and wired device
- End-to-end role-based security
- Seamless mobility across the hospital tor medical learns, patients, and visitors
- Cuts Wi-Fi deployment times from days to hours and enables Zero-Touch deployments across the site
- Establishes a resilient, future-ready network infrastructure with the intelligence, scalability, and intuitive toolsets to meet emerging needs
- Fully redundant branch solution with dynamic path selection to the hospital XYZ Regional Hospital is concerned about the performance of new latency-sensitive applications that will be introduced when connected via wireless.
Which solution can address this concern?
Answer: D
Explanation:
HPE Aruba Networking AirSlice is a unique technology specifically designed to guarantee performance for latency-sensitive applications in high-density Wi-Fi 6 (802.11ax) environments, such as a hospital. In medical environments, applications like voice over Wi-Fi, wireless fetal monitoring, or real-time imaging require consistent bit rates and low latency.
* Application Prioritization: AirSlice works by utilizing the OFDMA (Orthogonal Frequency Division Multiple Access) capabilities of Wi-Fi 6 to allocate dedicated "slices" of the radio frequency spectrum to specific high-priority applications.
* Latency Reduction: Unlike standard Quality of Service (QoS) which only prioritizes packets in a queue, AirSlice schedules the airtime at the radio level, ensuring that time-critical traffic does not have to compete with bulk data transfers or background traffic.
* Hospital Use Case: For XYZ Regional Hospital, this ensures that medical teams using handheld devices for patient care receive a "wire-like" experience even when the guest network is heavily utilized by visitors.
Why other options are incorrect:
* IDS/IPS (A): These are security features for detecting and preventing intrusions, not for managing application latency.
* Client Insight (C): This is a visibility and profiling tool used to identify and categorize connected devices, primarily for security and NAC purposes.
* AirMatch (D): While AirMatch optimizes the RF environment by managing channel assignment, channel width, and transmit power, it does so on a system-wide level rather than providing granular per- application latency guarantees.

Based on this campus design, click on the layer that is the most appropriate to be designed as a Stub Persona, considering an EVPN VXLAN Fabric?
Answer:
Explanation:
NEW QUESTION # 72
What is one use case for designing a 2-tier campus LAM instead of using a 3-tier?
Answer: A
Explanation:
A 2-tier campus LAN architecture, consisting of the core and access layers, is typically suitable for smaller campuses or networks with limited numbers of wiring closets. This simplified architecture eliminates the need for a dedicated aggregation layer, which is more common in larger, more complex network environments (the 3-tier architecture). In a small campus setting with only a few wiring closets, a 2-tier design can provide sufficient performance and scalability, reducing complexity and potentially lowering costs. This architecture allows for direct connectivity between the access layer, where end devices connect to the network, and the core layer, which routes traffic to and from the campus network. The use of a 2-tier architecture in such scenarios is driven by the network's size and the simplicity of its requirements, making it an efficient and effective choice.
NEW QUESTION # 73
Based on this campus design, which layer is the most appropriate to be designed as a Border Persona, considering an EVPN VXLAN Fabric?
Answer:
Explanation:
Explanation:
Based on the campus design provided and considering an EVPN VXLAN Fabric, the most appropriate layer to be designed as a Border Persona would be the "Services Aggregation" layer. In an EVPN VXLAN architecture, the Border or Border Leaf nodes provide connectivity to external networks, such as WAN, internet, or private connections. They are responsible for routing traffic into and out of the VXLAN fabric and typically also handle services like firewalling, load balancing, and other network services.
