Discover Requirements · Identify, collect, analyze, and document the current environment
As a Lead Architect, you are conducting a current-state discovery for a manufacturing plant planning to upgrade its campus access network. The customer currently operates a flat Layer 2 network using legacy third-party switches and wants to migrate to an HPE Aruba Networking routed access design. Which specific piece of current-state information is most critical to capture during discovery to prevent broadcast storms during the phased migration?
Answer and explanation
Correct answer: A
During a phased migration from a legacy Layer 2 network to a routed access design, the new and old networks will temporarily coexist. Understanding the specific STP variant (e.g., PVST+, MSTP, RSTP) and root bridge placement is critical to ensure Layer 2 interoperability and prevent loops or broadcast storms during the transition.

Discover Requirements · Define the technical requirements
During a requirements gathering workshop for a new university campus network, stakeholders provide various statements about what the new system must achieve. Which TWO of the following statements represent non-functional requirements rather than functional requirements? (Select TWO)
Answer and explanation
Correct answers: B, E
Scalability (supporting 25,000 concurrent clients) is a non-functional requirement as it defines the performance capacity of the system rather than a specific feature or behavior.
Non-functional requirements specify 'how well' a system must perform its functions, such as performance, availability, and scalability metrics. 99.999% availability is a classic non-functional requirement.

Discover Requirements · Define the technical requirements
A financial institution requires a new campus core network. The CIO states: 'Our trading floor applications cannot tolerate any dropped packets during maintenance windows or switch upgrades.' As an architect, how should you translate this business requirement into a specific HPE Aruba Networking technical requirement?
Answer and explanation
Correct answer: B
The business requirement demands hitless upgrades. In the HPE Aruba Networking CX portfolio, Virtual Switching Extension (VSX) combined with VSX Live Upgrade allows for independent control planes and orchestrated firmware upgrades that result in near-zero packet loss, directly satisfying the CIO's requirement.

Discover Requirements · Identify, collect, analyze, and document the current environment
You have been engaged to design a new campus access network for a large healthcare provider. The hospital consists of a main building and three adjacent clinics.
During discovery, the IT Director mentions that doctors use mobile workstations on carts (WOWs) that roam continuously between the clinics and the main building. These WOWs run a legacy charting application that relies on the client maintaining the same IP address; if the IP address changes, the application crashes and requires a 10-minute reboot process.
The hospital also has strict budget constraints and prefers to reuse their existing single-mode fiber infrastructure between buildings, which currently supports 10Gbps links. They want to manage the entire environment from a single cloud-based pane of glass.
Based on these discovery findings, which combination of requirements and constraints must drive your high-level design?
Answer and explanation
Correct answer: D
The legacy application's inability to handle IP changes dictates a strict requirement for seamless Layer 2 roaming across all buildings. The budget constraint explicitly dictates reusing the existing 10Gbps single-mode fiber. The design must accommodate these specific technical and physical constraints, likely pointing toward an overlay technology like EVPN-VXLAN or centralized AOS-10 forwarding to maintain Layer 2 over a routed underlay.
Q5Question 5
Beginner
Discover Requirements · Document assumptions
While conducting discovery for a municipal government campus, you find that the customer lacks up-to-date documentation regarding the fiber optic cabling between their 15 remote buildings and the main datacenter. The customer states they 'believe' all links are Single-Mode Fiber (SMF) capable of 10Gbps, but they cannot verify this. How should you formally handle this situation in your design documentation?
Answer and explanation
Correct answer: D
When critical data cannot be verified during discovery, it must be documented as an assumption. This protects the architect and clearly communicates the dependency and potential risk (e.g., needing different optics or facing bandwidth limitations) to the customer.
Q6Question 6
Beginner
Discover Requirements · Define the technical requirements
True or False: When discovering requirements, a business constraint (such as a strict IT budget or a mandated project completion date) should be converted directly into a technical requirement for the network architecture.
Answer and explanation
Correct answer: B
False. Business constraints (like budget or timelines) influence the design and limit technology choices, but they are not technical requirements themselves. Technical requirements dictate how the system must function and perform (e.g., protocols, throughput, availability).
