HPE7-A13 Sample Questions & Answers
Picking technologies and sketching a topology with a preliminary BOM ties with writing the technical proposal document and finalizing that BOM for the top weighting, alongside documenting today's environment and requirements, and defending the finished solution.

- Question 1Advanced
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?
Show answer & 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.
- Question 2Beginner
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?
Show answer & 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.
- Question 3Beginner
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.
Show answer & 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).
- Question 4Beginner
Discover Requirements · Identify, collect, analyze, and document the current environment
You are assessing a customer's installed base of network equipment to prepare for a campus refresh. The customer relies heavily on multicast video streaming for corporate communications. Which specific traffic metric is most critical to analyze during the current-state discovery to properly size the new core and aggregation switches?
Show answer & explanation
Correct answer: B
When sizing a network that relies heavily on multicast video, it is critical to analyze the peak bandwidth utilization to ensure adequate throughput, as well as the multicast state table sizes (IGMP/PIM entries) to ensure the proposed hardware can support the required scale.
- Question 5Intermediate
Discover Requirements · Define the technical requirements
During the discovery phase for a large enterprise campus, you identify that the customer has a strict requirement for micro-segmentation based on user roles, regardless of physical location. They also mandate that the solution must integrate natively with their existing third-party Identity Provider (IdP) via SAML. What is the most appropriate action to take with this information?
Show answer & explanation
Correct answer: D
Micro-segmentation based on roles and IdP integration are functional requirements that describe specific behaviors the system must perform. In the HPE Aruba Networking ecosystem, this directly drives the need for role-based access control (ClearPass) and potentially dynamic segmentation (Central NetConductor).
- Question 6Beginner
Build a high-level design · Identify technologies to satisfy requirements
A customer requires a cost-optimized wired access layer for a new 3-story office building. The requirements specify PoE+ for standard VoIP phones and Wi-Fi 6 access points, basic Layer 2 switching capabilities, and stacking up to 4 units per closet. Advanced Layer 3 routing protocols (like OSPF or BGP) are not required at the access edge. Which HPE Aruba Networking switch series is the most appropriate and cost-effective choice for this high-level design?
Show answer & explanation
Correct answer: A
The CX 6200 series is designed as a cost-effective, enterprise-class access switch that provides PoE+, Layer 2 features, and VSF stacking (up to 8 members), making it perfectly suited for cost-optimized access layer deployments that do not require advanced Layer 3 routing.
