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 is looking to utilize lower-cost OS-CX switches in their wiring closets. They calculate that each closet will need a stack of qty 6 PoE (AT) and qty 4 Gigabit Ethernet switches stacked with low-cost DACs.
Which series switch should you recommend?

• A. CX 6000
• B. CX 6300F
• C. CX 6100
• D. CX 6200M

ACME retail has 38 locations spread out across five US states and two provinces in Canada.
They are looking to grow 20% over the next two years. They have an HQ 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 sq m) and the Canadian warehouse is 130K sq ft (12100 sq m). The forklifts on the loading docks are equipped with a wireless tablet on board.
A typical store is reportedly about 60,000 sq ft (5575 sq m) and smaller stores are planned at
25,000 sq ft (2320 sq m). 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 Cat5, 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 be 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 half.
The office has an MDF and two IDFs located on floors one and two. The MDF is in the basement, and you have multiple WAN circuits for the HQ 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.
What should the architect be concerned about regarding the solution? (Choose two.)

• A. IP addresses
• B. multiple locations
• C. Regulatory Domains
• D. Active Directory

The client has provided floorplans, wall density, and ceiling heights for the wireless deployment in the carpeted office space.
What else will be needed to write an accurate bill of material? (Choose two.)

• A. PoE port details
• B. flooring information
• C. sprinkler details
• D. ceiling construction details

What is the best practice for using VSX at the core of a 3-tier design?

• A. VSX-lags allow the collapsed core to connect directly to services such as gateways and services only so long as spanning tree is used to prevent loops.
• B. You should never implement VSX at the core of a 3-tier redundancy core.
• C. You should implement VSX at the core when the aggregation layer operates at layer 2 only.
• D. You should implement VSX at the core when the aggregation layer is layer 3 only with OSPF- routed traffic forwarding between the core and aggregation layers.

You are delivering a replacement collapsed core network proposal to the customer where the core switches will have the switched virtual interfaces (SVI) configured. The customer is not sure that a VSX pair of switches will be able to act as the spanning tree root in their environment.
Which options are true about spanning tree and VSX that will help assure the customer that a VSX pair of switches are appropriate for a collapsed core? (Choose two.)

• A. When LAG interfaces are configured on a VSX pair of switches, both switches are "operational primary" and ensure active-active LAG operation equally.
• B. 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.
• C. 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. 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
• E. HPE Aruba Networking VSX switches support either multiple spanning tree (MSTP) or rapid per VLAN spanning tree (RPVST).
