質問 # 38
Match the deployment type with the usage scenario.
正解：
解説：
Explanation:
Capacity based design with low to mid density - Basic office/cubicle area with low to medium user density and no voice with limited rf redundancy.
Coverage based design - Coverage, office areas with higher user density OR basic coverage office/cubicle with High Demand users High-capacity design - High user density indoor space, with high demand users Very low-density, low coverage - Warehouses, large open areas The types of wireless network deployment should be matched to the usage scenarios based on the density of users and coverage requirements:
* Capacity based design with low to mid density is suitable for basic office or cubicle areas where there are not many users, and high-performance voice applications are not a priority, thus limited RF redundancy may be acceptable.
* Coverage based design is intended for areas where coverage is more critical than capacity. It could be used in office areas with higher user density, where maintaining a basic level of connectivity is more important than accommodating a large number of high-bandwidth connections.
* High-capacity design is used in environments where there is a high density of users who are likely to be using bandwidth-intensive applications. This could include indoor spaces like conference centers, auditoriums, or any area with a high concentration of users and devices.
* Very low-density, low coverage is typically for spaces like warehouses or large open areas where there are few users spread out over a large area. The focus here is on providing coverage to all areas, regardless of the low user density.

What is one use case for designing a 2-tier campus LAM instead of using a 3-tier?
- A. The network has grown beyond a few building aggregation points
- B. The campus has small buildings with only a few wiring closets.
- C. Cross-campus traffic has grown beyond We capacity of a single collapsed core
- D. Access aggregation points are not scaling to meet traffic demands.
正解：B
解説：
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.

質問 # 45
Match the deployment type to the estimated number of APs.
正解：
解説：
Explanation:
Capacity based design with low to mid density - 100,000 ft² / 900 m² building 100,000/10,000 = 10 APs Coverage based design - 100,000 ft² / 900 m² building 100,000/2,500 = 40 APs High-capacity design - 100,000 ft² / 900 m² building 100,000/1,500 = 67 APs Very low-density, low coverage - 100,000 ft² / 900 m² building 100,000/500 = 20 APs The deployment of Access Points (APs) in a wireless network design depends on the required density and coverage needed:
* Capacity based design with low to mid density is often used in environments like office spaces where there is a moderate amount of users and devices. Fewer APs are required compared to high-density scenarios.
* Coverage based design typically requires more APs than a low-density capacity design because the goal is to provide a wireless signal to all areas, regardless of the number of users.
* High-capacity design is for environments like stadiums or conference centers where a high number of users are expected to be concentrated in a particular area. Thus, a higher number of APs is needed to accommodate the user load.
* Very low-density, low coverage is suitable for areas that have few users over a large space, such as warehouses or outdoor areas. Fewer APs are required as the focus is on covering space rather than supporting a large number of devices.

Which is true when it comes to Aruba Central licensing for gateways? (Select two.)
- A. SD-WAN Gateway functionality requires security licensing.
- B. Aruba WLAN Gateway licenses allow normal SD-Branch features within a campus.
- C. Aruba SD-Branch Gateway licenses allow normal WLAN Gateway features within a campus.
- D. Aruba Gateway normal licensing is subdivided into three categories: Foundation, Advanced, and Foundation Base.
正解：C、D
解説：
Comprehensive and Detailed Explanation From Exact Extract:
* Aruba Central Licensing for GatewaysAruba has moved to a tiered subscription licensing model for gateways managed by Aruba Central. Licensing is divided into:
* Foundation Base - provides basic gateway management and monitoring.
* Foundation - enables standard gateway functionality such as WLAN gateway roles, routing, and tunneling.
* Advanced - adds enhanced capabilities such as SD-WAN features, security services, and advanced routing.
* Why Option A is CorrectAruba Central licensing for gateways is indeed subdivided into three categories: Foundation Base, Foundation, and Advanced. This aligns directly with Aruba's documented Central licensing structure.
* Why Option B is IncorrectSD-WAN functionality is not tied to "security licensing." Instead, SD- WAN features are unlocked with the Advanced license tier. Security services may also be enabled at that tier, but they are not a separate license requirement.
* Why Option C is CorrectAruba SD-Branch Gateways (with appropriate Central licensing) can also provide WLAN Gateway features in a campus deployment. This is explicitly supported in Aruba's ESP and Central design guides, where branch gateways can terminate WLAN tunnels and provide role-based policy enforcement in addition to SD-WAN.
* Why Option D is IncorrectThe reverse is not true - Aruba WLAN Gateway licenses do not allow SD-Branch features. A WLAN gateway license is designed for campus WLAN tunnel termination and policy enforcement, but does not include SD-WAN branch functions.
* Aruba Official Design Guide Reference:
* Aruba Central Licensing Overview: Gateway licensing is split into Foundation Base, Foundation, and Advanced.
* Aruba ESP Campus Design Guide: SD-Branch gateways can run both SD-WAN and WLAN Gateway roles when properly licensed.
* Aruba Central Feature Matrix: SD-WAN functionality requires the Advanced license tier, not a separate "security license."

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 10 GbE 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 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 the Internet connection is guaranteed.
Based on best practices, what should you recommend as the correct optic type for the connection between the IDF and the cabins?
- A. 10G SFP+ LC SR 300 m MMF Transceiver
- B. 10G SFP+ LC LRM 220 m MMF Transceiver
- C. 10G LC BiDi 40 km 1330/1270 XCVR
- D. 10GBASE-T SFP+ RJ-45 30 m Cat6A Transceiver
正解：A
解説：
Comprehensive and Detailed Explanation From Exact Extract:
* Cabling Type in Use:Each cabin and technical room is connected to the IDF with a single OM2 multimode fiber pair. The maximum length to cabins is 60 meters, and to technical rooms 100-150 meters.
* Best Practice for 10 GbE over OM2:According to Aruba's Campus Access Design Guides and HPE Aruba CX switch transceiver support matrices:
* OM2 multimode fiber supports 10GBASE-SR optics up to 82 meters.
* Since the maximum run is 60 meters, 10GBASE-SR is fully supported with headroom.
* 10GBASE-LRM can reach 220 m on MMF, but is not required here because the fiber length is much shorter. SR optics are simpler, lower cost, and recommended in best practices when distances are within OM2 limits.
* 10GBASE-T RJ-45 (Cat6A) is not applicable, as the cabling is fiber, not copper.
* BiDi 40 km optics are for long-haul single-mode fiber links, not short multimode fiber runs.
* Aruba Validated Design Reference:Aruba's Validated Solution Guides for Campus Access state that for short multimode connections (OM2/OM3/OM4), the recommended transceiver type is
10GBASE-SR (SFP+ LC) as it provides the most cost-effective and reliable option within the supported reach.
* Requirement Mapping:
* Uplinks to access switches in cabins/technical rooms must be 10 GbE capable.
* The OM2 cabling length (60-150 m) is within the supported distance for 10GBASE-SR.
* Therefore, the correct and most efficient optic choice is 10G SFP+ LC SR 300 m MMF Transceiver.
Final Justification:
Option B is correct because 10GBASE-SR over OM2 supports the required distances, aligns with Aruba design best practices, and avoids unnecessary cost/complexity of LRM or BiDi optics.
Reference Extracts (Aruba Official Study & Design Guides):
* Aruba Campus Access Design Guide: recommended transceiver selection for MMF cabling.
* Aruba CX Transceiver Guide: 10GBASE-SR supports OM2 up to 82 m, OM3 up to 300 m, OM4 up to
400 m.
* Aruba Validated Solution Guide: Always select SR optics for OM2 # 82 m runs as the cost-effective standard.

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)
- A. ceiling construction details
- B. sprinkler details
- C. flooring information
- D. PoE port details
正解：A、D
解説：
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.

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?
- A. Web Portal
- B. Tunneled Node
- C. Multi-Zone
- D. Airgroup
正解：B
解説：
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.
