  ACME retail has 38 locations spread out across Ave US states and two provinces in Canada. They are looking to grow 20% over the next two years. They have an HO with a staff of 200 employees. The organization has eight Regional Managers and two VPs who work from home and the road. Stores typically have 17 employees on average per location.

  The two warehouses have a remote loading system and 20 employees each to load the trucks and fulfill the online orders. The warehouse has 40-foot ceilings and large metal racks to store inventory. The main location is 240K sq ft (22300 st) m) and the Canadian warehouse Is 130K sq ft (12100 sq ml. The forkllfts on the loading docks are equipped with a wireless tablet on board.

  A typical store Is reportedly about 60.000 sq ft (5575 sqm) and smaller stores are planned at 25.000 sq ft '2320 sq mi. The locations need to expand the abilities to vendors that need to add setup displays or Interactive kiosks in the stores. The current Infrastructure was installed In 2015 and used wireless N technology in a coverage model. The wiring is CatS. and they are unsure of the fiber connections. The inventory is all placed on the floor when it is delivered to the local store.

  Inventory control is handled through Zebra barcode scanners, and they have had a lot of issues in getting signals throughout the stores and this makes monthly inventory difficult. The organization has a small help desk to troubleshoot issues that happen at the retail locations and PC support for the office. The company is looking to upgrade away from the current pbx system later this year. With the need to grow and cut costs, they are interested in moving the data to the cloud but need to get almost real-time inventory control for the online service to function.

  The network has all been wired over the last ten years, but with the new systems being all wireless, they have seen the trend to offer wireless to all the vendors for their needs but also would like to allow employees, guests, and contractors all to use it. With the new IT director starting next week, the project has been set by the CTO of the company. The marketing group has asked how they can interact with the customers and get more info, while the IT support desk needs to cut staff in halt.

  The. office has an MDF and two IDFs located on floors one and two. The HOF is in the basement, and you have multiple WAN circuits for the HO links. Each store has a local handoff from the cable company (ethernet) In the middle of the store in the office, so distance for the wiring is not an issue.

  The customer has budget concerns but does want something that could last 7+ years.

• Question 6:

  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 7:

  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.)

  A. The primary vsx switch ts the spanning tree root and the default behavior is the links on the secondary vsx switch are blocked with sub-millisecond failover assured by vsx active-gateway.
  B. When LAG interfaces are configured on a VSX pair of switches, both switches are "operational primary" and ensure active-active LAG operation equally.
  C. Both VSX switches are configured with the system MAC and then create unique STP bridge-IDs to identify "operational primary" and "operational secondary" for proper STP functioning
  D. Aruba VSX switches support either multiple spanning tree (MSTP) or rapid per VLAN spanning tree (RPVST).
  E. The ISL between VSX switches is never part of STP domain and doesn't send or receive BPDUs on this link and this ensures the "operational primary" and "operational secondary" switches are deterministic to other dual-attached switches.
  D. Aruba VSX switches support either multiple spanning tree (MSTP) or rapid per VLAN spanning tree (RPVST).
  E. The ISL between VSX switches is never part of STP domain and doesn't send or receive BPDUs on this link and this ensures the "operational primary" and "operational secondary" switches are deterministic to other dual-attached switches.

  ---

  Explanation

  According to Aruba Campus Access documents and learning resources, Aruba VSX (Virtual Switching Extension) technology is designed to provide advanced high availability and redundancy features for campus networks. Specifically, answer D is correct because Aruba VSX supports both Multiple Spanning Tree Protocol (MSTP) and Rapid Per VLAN Spanning Tree (RPVST), ensuring efficient tree structures for VLANs and rapid convergence in case of topology changes. Answer E is also true as the Inter-Switch Link (ISL) used for the VSX pair is not part of the Spanning Tree Protocol (STP) domain, meaning it does not send or receive Bridge Protocol Data Units (BPDUs). This design prevents the ISL from influencing STP calculations, ensuring that the operational roles of the primary and secondary switches in the VSX pair are clear and predictable to the rest of the network. This separation helps maintain deterministic behavior and failover capabilities in the network, aligning with the goals of a collapsed core network design.
