Which is true when it comes to Aruba Central licensing for gateways? (Select two.)
- A . Aruba Gateway normal licensing is subdivided into three categories: Foundation. Advanced, and Foundation Base.
- B . SD-WAN Gateway functionality requires security licensing.
- C . Aruba SD-8ranch Gateway licenses allow normal WLAN Gateway features within a campus.
- D . Aruba WLAN Gateway licenses allow normal SD-Branch features within a campus.
B C
Explanation:
In the context of Aruba Central licensing for gateways, it is true that SD-WAN Gateway functionality requires a specific security licensing (Option B), which is essential for enabling advanced security features and capabilities in an SD-WAN deployment. This includes functionalities like firewall, threat management, and secure VPN connections. Additionally, Aruba SD-Branch Gateway licenses allow for the use of standard WLAN Gateway features within a campus environment (Option C). This means that with an SD-Branch Gateway license, the gateway can handle traditional WLAN management and security tasks, in addition to its SD-WAN capabilities, providing a unified solution for both branch and campus deployments.
A global cruise line company needs to refresh its current fleet. They win refresh the insides’ of the ship to be cost-effective and increase their sustain ability. They Mill replace the complete WLAN/LAN hardware of the ship. In this refresh, the company will not refresh Us 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 (930 ft) and the type used is 0S1. Each cabin is connected by a single 0M2 pair to the IDF. the maximum length is 60 meters (200 ft). Each technical room is connected by a single 0M2 pail 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 10GbEto 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 instant OS (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 Internet connection is guaranteed.
Based on the best practices, what should you recommend as the correct optic type for the connection between the IDF and the cabins?
- A . Aruba 106 SFP- LC LRM 220 m MMF Transceiver
- B . Aruba 10GBASE-T SFP- RJ–35 30 m Cat6A Transceiver
- C . Aruba 106 SFP- LC SR 300 m MMF Transceiver
- D . Aruba 10G LC BiDi 40 km-D 1330/1270 XCVR
C
Explanation:
For the connection between the IDF and the cabins, which requires supporting distances up to 60 meters on OM2 fiber, the most appropriate optic type is the Aruba 10G SFP+ LC SR 300 m MMF Transceiver. This transceiver is compatible with multi-mode fiber (MMF) and is capable of supporting the required distance for connections to the cabins, making it a suitable choice based on the company’s existing cabling structure and the need for 10GbE uplink capabilities to manage increased network traffic. The SR (Short Range) designation indicates that this transceiver is optimized for short to medium distances, which aligns with the maximum 60-meter distance from IDF to cabins, ensuring reliable and high-speed connectivity for the ship’s LAN infrastructure within the given physical constraints.
when is o Mode Conditioning Patch Cable required?
- A . A1000Base-LX Transceiver is operated with 62.5/125 cables up to 500 m.
- B . A1000Base-SX Transceiver is operated with 62.5/125 cables up to 500 m.
- C . A10GBase-LXd Transceiver Is operated with 62.5/125 cables up to 2 km.
- D . A10GBase-lR Transceiver is operated with 62 5/125 cables up to 500 m
A
Explanation:
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.
