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. To ensure broad client compatibility, custom radio profiles should include channels 169, 173, and
  177.
• C. The HPE Aruba Networking Central default radio profile has Dynamic Frequency Selection (DFS) channels disabled, as defined by the 802.11h standard.
• D. 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.
• E. With 1024-QAM or higher designs, it is common to disable some APs' 2.4 GHz radios for client use.

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 to market additional tools to its retail customers. The desire is to make a Blue Dot wayfinding app available to any customer to allow them to locate stores and services within the retail space. They would also like to have directed pop-ups within the app appear when a customer walks within close proximity to any of the 10 "Promotional Kiosks".
What licensing will be needed to make this retail solution a reality? (Choose two.)

• A. qty 1 Meridian Map subscription
• B. qty 10 HPE Aruba beacons
• C. qty 2 Meridian Map subscriptions
• D. qty 2 Meridian Blue Dot subscriptions

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 additional question needs to be answered in order to collect needed information for the WLAN design?

• A. Who Is the campus switch vendor?
• B. Is there enough cooling in the MDF?
• C. What type or fiber connection it used between the core and access layer switches?
• D. Does the existing wired network support enough drops for an upgraded Wi-Fi Network?

'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?

• A.
  
• B.
  
• C.
  
• D.
