HPE4-A54 Sample Questions

  1. Question 1

    Intermediate

    Discover Requirements · Identify, collect, analyze, and document the current environment

    You are assessing a customer's current environment for a campus core upgrade to HPE Aruba Networking CX switches. The customer currently uses a legacy 3-tier architecture with MSTP for loop prevention. They have experienced occasional network-wide outages due to broadcast storms. Which discovery action is MOST critical before proposing a modern AOS-CX VSX core deployment?

    Answer and explanation

    Correct answer: A

    When migrating from a legacy spanning tree environment to a VSX core, it is critical to understand the existing MSTP configuration (regions, revisions, root placement). VSX switches can participate in MSTP, but misconfigurations during migration (such as mismatched region names) can isolate the new core or cause loops. Understanding the root bridge placement allows the architect to plan the shift of the root to the new VSX core.

  2. Question 2

    IntermediateMultiple answers

    Discover Requirements · Define the technical requirements

    During a requirements discovery workshop, a university CIO states: 'We need to reduce our operational expenses by 20% over the next three years while ensuring students can connect seamlessly across the entire 50-building campus.' Which TWO of the following represent the translation of these business goals into verifiable technical requirements? (Select TWO)

    Answer and explanation

    Correct answers: A, B

    The business goal of reducing operational expenses translates to technical requirements for centralized management, automation, and AIOps (provided by Aruba Central) to reduce IT overhead and troubleshooting time.

    The business goal of 'connecting seamlessly across the entire campus' translates technically to a requirement for fast roaming (Layer 2 or Layer 3 roaming with session persistence), which often dictates the use of Aruba Gateways or EVPN-VXLAN to stretch subnets or handle mobility.

  3. Question 3

    Intermediate

    Discover Requirements · Document assumptions

    You are designing a wireless network for a historical building where the customer cannot provide architectural floor plans with accurate wall attenuation values. A physical site survey is not permitted until after the contract is signed. How should you properly document this situation in your design proposal?

    Answer and explanation

    Correct answer: A

    When critical data (like wall attenuation in a historical building) is missing and cannot be obtained, the architect must document a baseline assumption (e.g., standard drywall or brick) and clearly state the associated risk that the Bill of Materials (BoM) and design may require modification once a physical survey is conducted.

  4. Question 4

    Beginner

    Discover Requirements · Identify, collect, analyze, and document the current environment

    True or False: When discovering requirements for a greenfield deployment, analyzing the existing network topology is completely unnecessary since all new HPE Aruba Networking hardware will be installed.

    Answer and explanation

    Correct answer: B

    False. Even in a greenfield deployment (new hardware), the new network must often integrate with existing upstream ISP connections, shared WAN infrastructure, legacy authentication servers (RADIUS/AD), or physical cabling constraints. Therefore, some analysis of the existing environment is still required.

  5. Question 5

    Advanced

    Discover Requirements · Identify, collect, analyze, and document the current environment

    A large hospital is refreshing its campus network. During discovery, you map out their current architecture (see diagram). They require seamless roaming for VoIP devices across all wards. The current design uses traditional L2 VLANs stretched across multiple access switches, leading to large broadcast domains. Which constraint MUST you document when proposing a migration to a routed access layer with EVPN-VXLAN?

    flowchart TD Core[Legacy Core] -->|L2 Trunk| Agg1[Agg Switch 1] Core -->|L2 Trunk| Agg2[Agg Switch 2] Agg1 -->|VLAN 10,20| Acc1[Ward A Access] Agg2 -->|VLAN 10,20| Acc2[Ward B Access] Acc1 -.->|VoIP Roaming| Acc2
    Answer and explanation

    Correct answer: B

    When migrating from a centralized gateway (legacy core) to a distributed anycast gateway (EVPN-VXLAN at the access/agg layer), the migration is a major constraint. You cannot easily have the same subnet gateway active on both the legacy core and the new VXLAN fabric simultaneously without careful routing and L2 extension planning (like using a border leader or L2 DCI). This constraint must be documented.

  6. Question 6

    Beginner

    Discover Requirements · Identify, collect, analyze, and document the current environment

    When performing network discovery, an architect needs to quickly map the physical topology of third-party IP phones and APs connected to an existing Aruba CX switch. The architect should use the _____ protocol command outputs to identify these directly connected neighbors.

    Answer and explanation

    Correct answer: B

    Link Layer Discovery Protocol (LLDP) is the vendor-neutral standard protocol used to discover directly connected devices, such as IP phones, APs, and other switches. Viewing LLDP neighbors is a fundamental step in physical topology discovery.
