NEW QUESTION # 24
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 sq m). Data centers are all offsite 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 modem 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 decided that more critical switch stacks supporting Contact Center resources will need to support greater than 600W of CL4 PoE and have redundant power supplies. These stacks will have approximately six members.
What would be the most economical choice switch series to meet these requirements?
Answer: C
Explanation:
The Aruba CX 6300F Switch Series is well-suited for environments requiring high PoE power and redundancy in power supplies, especially for critical applications like supporting contact center resources. This series offers robust PoE capabilities, often exceeding 600W of Class 4 PoE power, making it ideal for powering multiple high-powered devices. Additionally, the Aruba CX
6300F supports stack configurations and redundant power supplies, ensuring high availability and reliability for critical network infrastructures. Its economical pricing, combined with high performance and reliability, makes it the most cost-effective choice for the client's requirements.
NEW QUESTION # 25
What are the considerations when using existing MMF and upgrading to equipment capable of 10 GbE speeds? (Select two)
Answer: A,D
Explanation:
When upgrading existing Multimode Fiber (MMF) infrastructure to accommodate equipment capable of 10 GbE speeds, two primary considerations are the length of the MMF fiber (Option A) and the type of MMF fiber (Option C). The length of the fiber impacts the signal quality and bandwidth capacity, with longer lengths potentially requiring signal conditioning or different types of fiber to support higher speeds. The type of MMF fiber, such as OM1, OM2, OM3, or OM4, significantly affects its bandwidth capabilities and distance limitations at 10 GbE speeds. OM3 and OM4 fibers are designed to support 10 GbE transmissions over longer distances compared to OM1 and OM2, making them more suitable for upgrades to higher speeds.
Understanding these factors is crucial to ensure the existing fiber infrastructure can support the desired network performance without extensive modifications or replacements.
NEW QUESTION # 26
Which is true when it comes to Aruba Central licensing for gateways? (Select two.)
Answer: A,B
Explanation:
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."
NEW QUESTION # 27
A global furniture retail company called 'No-Stair Inc.' requests you design their new WLAN Infrastructure for a global footprint. Each location of 'No-Stair Inc ' has a similar layout: three small manager offices, a warehouse, and a 'retail' area. The 'retail' area and the warehouse together amount to 95% of the location. The IT department of the company is minimally engaged in their LAN refresh so the CTO of the company has shared the Information below.
Current WLAN Infrastructure is based on the 802.11 n "WIFI4Less' access-points series (both model 2013- INT (2.4 only internal antenna) and model 2019-EXT (dual-band external antenna only}). These AP models are standalone without any centralized management. Last year 'No-Stair Inc' ran a project called 'secure-it' ensuring that all needed network security was implemented to be fully compliant with their security standards.
During this project, they also upgraded the AAA infrastructure to handle the increased AAA requests. No additional Wi-Fi or security requirements are listed for this WLAN refresh, which means that 'No-Stair Inc.' will continue to use bridged SSlDs. with local breakout into different VLANs.
The CTO of "No-Stair Inc.' understands the need for you to ask additional questions to deliver the design. The questions may be sent in written form and will be answered within two weeks What is a possible constraint?
Answer: D
Explanation:
In the Aruba design methodology, identifying constraints is a critical step in the "Gathering Requirements" phase. A constraint is a factor that limits the design options available to the architect.
* Client Compatibility as a Constraint: For a retail and warehouse environment like "No-Stair Inc.", business operations typically rely on specific end-user devices such as handheld scanners, Point of Sale (POS) terminals, and mobile inventory systems. If these business-critical devices only support older bands (like 2.4 GHz) or lack support for newer standards (like Wi-Fi 6E/6 GHz), it acts as a significant constraint on the radio frequency (RF) design and the selection of Access Points.
* Why other options are less likely to be "constraints" in this context:
* AAA Infrastructure (D): The scenario explicitly states that the company recently completed a project called "secure-it" where they upgraded their AAA infrastructure to be fully compliant and handle increased requests. Therefore, this is likely a requirement or a known capability rather than a constraint.
* WAN (A) and Core Switching (C): While these are important for the overall solution, the scenario specifies the use of bridged SSIDs with local breakout. This means traffic is handled locally at the edge, making the existing WAN less of a direct constraint on the WLAN performance compared to the capabilities of the wireless clients themselves.
* Architectural Focus: An architect must ensure the "New WLAN" supports the existing "Business- Critical" devices. If the devices are legacy 2.4 GHz only, the architect is constrained from implementing a 5 GHz/6 GHz-only high-density design.
NEW QUESTION # 28
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.
