NEW QUESTION # 67
What is true about 1000 Base-LX single mode transceivers?
Answer: D
Explanation:
The 1000Base-LX standard is designed primarily for single-mode fiber (SMF) but can also operate over multi- mode fiber (MMF). However, when using a 1000Base-LX (long wavelength) transceiver with older multi- mode fiber like OM1 ($62.5/125$ $\mu m$), a specific technical issue called Differential Mode Delay (DMD) occurs.
* Mode Conditioning Patch (MCP) Cable: To mitigate DMD, an MCP cable must be used when connecting a 1000Base-LX transceiver to OM1 or OM2 multi-mode fiber for distances up to 550 meters. This cable offsets the laser launch into the fiber core to ensure the signal propagates correctly.
* OM1 Specifics: OM1 fiber has a smaller bandwidth-distance product compared to newer standards.
Without the MCP, the signal distortion makes the 550m distance unattainable or unreliable.
* Comparison: * OS1 (Option D): This is single-mode fiber. 1000Base-LX transceivers are native to single-mode and do not require mode conditioning cables for OS1/OS2.
* OM5 (Option A): While technically possible, MCPs are typically associated with the legacy
$62.5$ $\mu m$ (OM1) and $50$ $\mu m$ (OM2) fiber types.
* OM2 (Option C): Standard practice dictates that OM2 also requires an MCP for 1000Base-LX at
550m to avoid DMD, making "doesn't need" incorrect.

Answer: A,D
NEW QUESTION # 69
'Don't Buy at Us' is a US-based retail company that is expanding Into Europe. They are expanding into EMEA with a regional headquarters called HQ2 inside The Netherlands. Their US- based headquarters HQ1 was refreshed last year based on the HPE Aruba Networking ESP architecture. You have created the design for HQ2 based on the same design as HQ1, a two-tier architecture. The high level is shown below.
Switch BOM for this project based on Two Tier:
Collapsed Core: 2 x 8360-16Y2C in VSX (ISL 2x100GbE DAC)
Access Stack: 10 x Stack of 6200F 48G Class4 PoE 4SFP+ 740W (each stack has 4 members, VSF with 10GbE VSF links) (2 x 10GbE uplink per stack) During the presentation of your design to the CTO of 'Don't Buy at Us' you were informed about the updated fiber infrastructure that Don't Buy at Us' has installed in HQ2.
The core stack is Installed in the MDF and per IDF there is one access stack installed. Based on best practice, what is the most cost-effective update to the switch BOM?
Answer: A
Explanation:
This option uses the Aruba 6200F access switches, which are appropriate for a cost-effective solution while meeting the uplink requirements. The selection of optics (SR for shorter distances and LR for longer distances) is based on the fiber infrastructure provided, ensuring efficient connectivity across the MDF and IDFs.
NEW QUESTION # 70
What possible issue with the cote switch selection do you see in regards to the customers' requirements?
Answer: A
Explanation:
* Customer Requirement Recap (cruise line scenario):
* Each ship has two core switches in the MDF.
* Each core connects to up to 10 distribution switches in IDFs.
* Uplinks between core and distribution are 25 GbE SMF links.
* Cabins/technical rooms connect to distribution switches via 10 GbE uplinks.
* Only 8 uplinks per core switch are required to meet the design.
* Issue Identified:
* The selected core switch platform provides dozens of 25/40/100 GbE ports, far exceeding what is needed for this environment.
* With only 8 ports in use per core, that leaves ~40 unused ports.
* This creates a cost inefficiency - the customer is paying for hardware capacity that will remain idle.
* Why the Correct Answer is B:
* The main "issue" is not about lack of capability (uplinks and VSX are supported).
* The issue is about overprovisioning - the core switch selection results in a large number of unused ports, which is against the CIO's requirement to limit unused capacity and avoid waste.
* Why Not the Other Options:
* A. Core will not support 25 GbE downlinks # Incorrect. The selected core switches do support
25 GbE uplinks.
* C. Not enough ports for VSX links # Incorrect. Core switches only require a few ports for VSX interconnect, which is easily supported.
* D. Core will not support 10 GbE downlinks to cabins # Incorrect. Core switches don't connect directly to cabins; those connections terminate at the distribution layer.
Aruba Design Guide Reference:
* Aruba ESP Campus Design Principles: Switch sizing should consider right-sizing the port count to avoid excessive unused capacity.
* Aruba Validated Solution Guides: Core switches should be selected for performance, scalability, and efficiency - not overspec'd beyond realistic need.
Final Justification:
The issue with the customer's core switch selection is not about functionality, but about efficiency. Only 8 uplinks per core are needed, leaving ~40 ports unused - which contradicts the CIO's goal of minimizing unused ports.
NEW QUESTION # 71
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 A Regional Hospital will be implementing RADIUS authentication across all their switches. They are looking for a solution wherein they can use HPE Aruba Networking ClearPass Policy Manager to allow staff members from five different teams (AV team, security team, desktop/printer team, voice team, network & security team) to register these types of devices and control access to them to a specific team.
This registration, visibility, and access control to devices must be self-service In addition, device registration needs to be removable on a scheduled basis.
What is the most appropriate solution for the hospital's requirements?
Answer: C
