What is the best practice for using VSX at the core of a 3-tier design?

• A. You should implement VSX at the core when the aggregation layer is layer 3 only with OSPF- routed traffic forwarding between the core and aggregation layers.
• B. VSX-lags allow the collapsed core to connect directly to services such as gateways and services only so long as spanning tree is used to prevent loops.
• C. You should implement VSX at the core when the aggregation layer operates at layer 2 only.
• D. You should never implement VSX at the core of a 3-tier redundancy core.

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 802.11n "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 SSIDs, 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?

• A. Do the business-critical end devices being used support 5 or 6Ghz?
• B. Does the existing AAA infrastructure support an upgraded Wi-Fi Network?
• C. Does the existing WAN infrastructure support an upgraded Wi-Fi Network?
• D. Does the existing core switch support an upgraded WiFi Network?

As part of several technical proposals for a customer deploying both Wi-Fi 7 high-throughput HD and very high-throughput VHD networks based on HPE Aruba Networking AOS-10, you are outlining key considerations for radio frequency (RF) design and channel optimization.
Which statements represent recommended AOS-10 best practices for RF planning and should be included in your proposals to ensure optimal wireless performance? (Choose two.)

• A. UNII-4 channels in radio profiles should not be enabled in Guest environments in most situations.
• B. The Wi-Fi Alliance's Wi-Fi 6 standard can utilize channel widths from 20 MHz up to 160 MHz without relying on DFS channels.
• C. To ensure broad client compatibility, custom radio profiles should include channels 169, 173, and
  177.
• D. With 1024-QAM or higher designs, it is common to disable some APs' 2.4 GHz radios for client use.
• E. The HPE Aruba Networking Central default radio profile has Dynamic Frequency Selection (DFS) channels disabled, as defined by the 802.11h standard.

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 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 would you recommend as the correct optic type for the connection between the MDF and the IDFs?

• A. 25G SFP28 LC eSR 400 m MMF Transceiver
• B. 25G SFP28 LC LR 10 km SMF Transceiver
• C. 50G SFP56 LC SR 100 m MMF Transceiver
• D. 10G SFP+ LC LR 10 km SMF Transceiver

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.
