Question 1
'Don't Buy at Us' is a US-based retail company that is expanding Into Europe. They are expanding into EMEA with a regional headquarters called HQ2 inside The Netherlands.
Their US-based headquarters HQ1 was refreshed last year based on the Aruba ESP architecture. You have treated the design for HQ? based on the same design as HQ1. a two-tier architecture. The high level is shown below.
Switch BOM for this project based on Two Tier:
Collapsed Core: 2 x Aruba 8360-16Y2C in VSX (ISL 2 ICOG0E DAC)
Access Slack: 10 x Slack of Aruba 6200F 48G Class4 PoE 4SFP- 740W each stack has A members. VSF
with 10GbE VSF links) 12 x 10GbE uplink pet stack)
During the presentation of your design to the CTO of 'Don't Buy at Us' you were informed about the updated fiber infrastructure that Don't Buy at Us' has installed in HQ2.
The core stack is Installed in the MDF and per IOF there is one access stack installed. Based on best practice, what is the most cost-effective update to the switch BOM?
A)
B)
C)
D)
Answer : B
Option B is the most cost-effective solution, as it does not include long-range optics, which are unnecessary given the distances and fiber types specified. The 10GbE-SR optics are suitable for short-range connections up to 300 meters over OM3 fiber and would cover the needs of the longest fiber run mentioned, which is 250 meters. The 10GbE-LRM optics, while capable of reaching up to 220 meters over OM2 fiber, would not be necessary as the longest OM2 run is 71 meters, which is within the range of standard 10GbE-SR optics. Thus, Option B provides the required connectivity without incurring additional costs for long-range optics that are not needed given the fiber infrastructure of HQ2.
Question 2
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 would take to ensure redundant RADIUS resources in each of their three geographical regions (AMER. EME
Answer : B
In the scenario provided, each of the clients in the three geographical regions (AMER, EMEA, and APAC) will require OnGuard licensing for health validation through a local agent, covering both wired and wireless authentications as well as personal device Wi-Fi authentication. Given the client counts range between 4,435 and 5,859 in each region, and assuming the upper limit for planning purposes, we have approximately 5,859 clients per region. Multiplying by three regions gives us 17,577, which would be rounded up to the nearest available licensing tier. In this case, 15,000 licenses would not be sufficient, so the next logical tier would likely be around 20,000 licenses. However, since this exact number isn't an option, and based on the principle of providing the most accurate and cost-effective solution, the best estimate with the given options would be 15,000, understanding that this might involve purchasing additional licenses to cover the exact needs.

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 or 25Gbps over OM4 MM fiber They would also like to keep the stacking cabling cost to a minimum.
Which stacking components would be required to meet the customer's requirements in the most cost-effective way if the closets were 190 m (620 ft) apart? (Select two.)
Answer : B, D
To meet the customer's requirement of managing two wiring closets as a single stack with a minimum transport speed of 25Gbps over OM4 MM fiber, especially when the closets are 190m apart, the most cost-effective solution would involve using SFP transceivers. SFP28 transceivers can support speeds up to 25Gbps, aligning with the customer's minimum speed requirement. For higher speeds or future-proofing, SFP56 transceivers, which can support speeds up to 50Gbps, could also be considered. Both types are compatible with OM4 multimode fiber, which is capable of supporting these high speeds over the distance specified. DAC (Direct Attach Cable) solutions like options A and C would not be feasible due to the 190m distance between the closets, as DAC cables are typically used for much shorter distances.
