• Question 2:

  DRAG DROP

  Match the deployment type with the usage scenario.

  Select and Place:

  

  

  Explanation

  Capacity based design with low to mid density - Basic office/cubicle area with low to medium user density and no voice with limited rf redundancy.Coverage based design - Coverage, office areas with higher user density OR basic coverage office/cubicle with High Demand usersHigh-capacity design - High user density indoor space, with high demand usersVery low-density, low coverage - Warehouses, large open areas

  The types of wireless network deployment should be matched to the usage scenarios based on the density of users and coverage requirements:

  Capacity based design with low to mid densityis suitable for basic office or cubicle areas where there are not many users, and high-performance voice applications are not a priority, thus limited RF redundancy may be acceptable.

  Coverage based designis intended for areas where coverage is more critical than capacity. It could be used in office areas with higher user density, where maintaining a basic level of connectivity is more important than accommodating a large number of high-bandwidth connections.

  High-capacity designis used in environments where there is a high density of users who are likely to be using bandwidth-intensive applications. This could include indoor spaces like conference centers, auditoriums, or any area with a high concentration of users and devices.

  Very low-density, low coverageis typically for spaces like warehouses or large open areas where there are few users spread out over a large area. The focus here is on providing coverage to all areas, regardless of the low user density.

• Question 5:

  Which alternative source is best suited for site surveys or simul-ations if no floor plans are available?

  A. blank sheet of paper
  B. Google Maps
  C. simple wall drawings
  D. tire escape plan
  D. tire escape plan

  ---

  explanation:

  Explanation

  When floor plans are not available for site surveys or simulations, the best alternative source to use is the fire escape plan (Option D). Fire escape plans are typically available in most buildings and provide a simplified layout of the premises, including walls, doors, and sometimes the location of permanent fixtures. While not as detailed as architectural floor plans, fire escape plans can offer enough information for initial site survey estimations and RF planning. They allow network designers to understand the basic layout and potential RF obstacles or coverage areas, making them a practical tool for preliminary wireless network planning and simulations in the absence of more detailed floor plans.

• Question 6:

  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 L2based 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?

  A. Tunneled Node
  B. Multi-Zone
  C. Airgroup
  D. Web Portal
  A. Tunneled Node

  ---

  explanation:

  Explanation

  To control exposed printer, conference room, and VoIP phone connections with a stateful firewall, utilizing Tunneled Node functionality would be effective. Tunneled Node allows for the encapsulation of wired Ethernet traffic into a user-based tunnel, similar to how wireless traffic is handled. This means that traffic from these devices can be sent through a centralized controller where stateful firewall policies can be applied. This setup ensures that the specific ports used by these devices are subjected to the same level of security scrutiny and policy enforcement as wireless traffic, aligning with the client's requirements for a secure and controlled network environment.
