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 sqm). Data centers are all off site 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 modern 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 decides that they would like for all of their exposed printer, conference room, and VoIP phone
connections to be controlled by a stateful firewall
What could be planned to ensure that these ports will meet the customer's requirements?
You are delivering a replacement collapsed core network proposal to the customer where the core switches will have the switched virtual interlaces (SVl) configured. The customer is not sure that a USX pair of
switches will Be able to act as I tie spanning tree root in their environment.
Which options are true about spanning tiee and VSX that will help assure the customer that a VSX pair of
switches are appropriate for a collapsed core? (Select two.)
The clients existing network isexperiencing trouble with voice occasionally dropping out on phone calls
between office locations, it Is determined that no packet loss is occurring and QOS is likely the cause. With
what phenomenon Is the client currently experiencing issues?
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 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 and customer requirements, what is the correct LAN approach?
