A large multinational financial institution has engaged you to design a new full-stack wired and wireless network for its new 6-story regional office building. The facility's bottom two floors will be retail space for a large banking branch. The upper floors will be carpeted corporate office space, with each floor approximately
100,000 sq ft (9290 sq m). Data centers are all offsite and are outside this project's scope. The customer is underserved by its current L2-based network infrastructure and wants to use modern best practices in the new design. The network must be fully resilient and fault-tolerant, with dynamic segmentation at the edge.
The retail space will provide public guest Wi-Fi access. Retail associates will use corporate tablets for customer service, and the retail floors will contain a mixture of wired and wireless devices. Corporate users will primarily connect wirelessly, although several wired clients, printers, and hard VoIP phones will be used.
The customer also plans to renovate the corporate office space to take advantage of 'smart office' technology.
These upgrades will enable blue-dot wayfinding, presence analytics, and other location-based services.
After further discussions with the customer, the team determined that EVPN-VXLAN will provide dynamic segmentation. The customer wants to ensure that a particular VNI is present only when it is used on that switch.
Which solution is valid and meets this technical requirement?

• A. A single virtual chassis of four 8325s serves as a collapsed distribution/edge layer. The 8325s provide edge connectivity and serve as the VTEPs.
• B. Two 8320 switches in a VSX pair as a distribution layer. Two VSF stacks of 6300s as edge switches.
  The 8320s are configured as the VTEPs.
• C. Two 6300 switches in a VSX pair as a distribution layer. Two VSF stacks of 6100s as edge switches.
  The 6100s are configured as the VTEPs.
• D. Two 8325 switches in a VSX pair as a distribution layer. Two VSF stacks of 6300s as edge switches.
  The 6300s are configured as the VTEPs.

A global cruise line company needs to modernize its existing fleet. It will refresh the ship's "insides" to improve cost-effectiveness and sustainability, replacing all WLAN/LAN hardware. During this refresh, the company will retain its existing security requirements. The CIO also wants to minimize unused switch ports.
Any future expansion will always involve a hardware refresh. The project begins with the smallest ship, which has a maximum of 800 guests.
Each ship has a LAN infrastructure comprising two core switches, up to 10 redundant distribution switches, and up to 500 access switches (400 cabins and 100 technical rooms). The core switches are in the ship's MDF, and the distribution switches are in the IDFs. Every cabin and technical room receives one access switch.
The ship's cabling structure will remain unchanged. Each IDF connects to the MDF through SMF, with two pairs available for the interconnect between core and distribution. The SMF distance between MDF and IDF is under 300 meters (980 ft), and it is OS1. Each cabin connects to the IDF through a single OM2 pair, with a maximum distance of 60 meters (200 ft). Each technical room connects to the IDF through a single OM2 pair, with distances from 100 to 150 meters (320 to 500 ft).
For every cabin and technical room, the customer wants to replace the existing fan-less 2530/2540 switches without changing requirements, except that the uplink to the distribution switch must be upgraded to 10GbE to accommodate increased network traffic, and technical rooms require redundant power.
The WLAN infrastructure will be refreshed 1:1, with no new cabling or AP locations. It uses 200/300 series indoor and outdoor APs running InstantOS (fewer than 300 APs), and the customer has no WLAN requirement changes.
The cruise line company will replace its existing Internet connection before the LAN/WLAN refresh. The new Internet connection will provide 99.8% uptime, needed to keep paid guest Wi-Fi operational. With this new Internet connection, the CIO wants to base the design on Aruba's ESP architecture because the Internet connection is guaranteed.
Based on best practices, what optic type should be recommended for the connection between the IDF and the cabins?

• A. 10G SFP+ LC SR 300 m MMF Transceiver
• B. 10G BASE-T SFP+ RJ-45 30 m Cat6A Transceiver
• C. 10G LC BiDi 40 km-D 1330/1270 XCVR
• D. 10G SFP+ LC LRM 220 m MMF Transceiver

The client has decided to manage two wiring closets as one stack totaling 10 switches, with a minimum transport speed of 25Gbps over OM4 MM fiber. They also want to minimize stacking-cabling cost.
Which switch series would most economically meet these requirements?

• A. 6300F Switch Series
• B. 6200F Switch Series
• C. 6400 Switch Series
• D. 6100 Switch Series

XYZ Regional Hospital is an integrated healthcare system consisting of hospitals, neighborhood health centers, and small doctor offices.

An insurance company plans to modernize the current Wi-Fi 4 deployment in its downtown office building.
At the time, the network was designed around a 2.4 GHz radio-coverage strategy. The company is targeting a high-throughput, high-density (HD) design to future-proof its investment. Your team is proposing a new site survey aligned with modern wireless design principles.
The CTO believes the site is ready for the Wi-Fi 6E standard or newer, referring to a site survey conducted four years ago. That same survey confirmed reuse of the existing cabling and current access-point installation locations.
Which statement about a 6 GHz design is correct?

• A. The 6 GHz band has a noticeable higher Free-space path loss (FSPL) than 2 4 GHz band.
• B. A site survey could prove the 6 GHz radios can increase signal strength without concerns of interference with non 802.11 technologies.
• C. Since Wi-Fi 4 and Wi-Fi 6E support the 5 GHz band, a site survey would confirm a one to one AP replacement in the same locations.
• D. With limited 6 GHz client support today, a new site survey should be done to focus on 5 GHz for compatibility.
