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 decided that they would like to manage two wiring closets as a single stack with a total of 10 switches and a minimum transport speed of 25Gbps over OM4 MM fiber. They would also like to keep the stacking cabling cost to a minimum.
Which switch series would most economically accomplish these requirements?

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

Through additional conversations with the customer, the team has determined that they will use EVPN-VXLAN to deliver dynamic segmentation. The customer wants to ensure that a particular VNI is only present when it is in use on that switch.
Which solution is valid and satisfies this technical requirement?

• A. 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
• B. 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
• C. 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
• D. A single virtual chassis of four 8325s serves as a collapsed distribution/edge layer.
  The 8325s provide edge connectivity and serve as the VTEPs.

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 is the most cost-effective switch model for the distribution?

• A. 6300M 24-port HPE Smart Rate 1/2.5/5GbE Class 6 PoE and 4-port SFP56
• B. 6300F 24-port SFP+ and 4-port SFP56
• C. 16300M 24p SFP+ LRM support and 2p 50G and 2p 25G MACsec
• D. 6300M 48SR5 12p Class8 PoE and 36p Class6 PoE HPE Smart Rate 1G/2.5G/5G and 2p 50G and 2p 10G LRM

What is the difference between OM4 and OM5 cabling? (Choose two.)

• A. OM4 supports distances up to 100 m. while OM5 supports distances up to 150 m using 100 GBps transceivers.

• C. OM5 supports Multiplexing operating in the 850 to 950 nm range, while OM4 does not
• D. OM5 is approved as wide Band Multimode Fiber (WBMMF), while OM4 is not.

What is one use case for designing a 2-tier campus LAM instead of using a 3-tier?

• A. The campus has small buildings with only a few wiring closets.
