HPE4-A51 Sample Questions

  1. Question 1

    Intermediate

    Device Management and Onboarding · Zero Touch Provisioning (ZTP) and One Touch Provisioning (OTP)

    A large university is deploying 500 HPE Aruba Networking APs across a new campus extension. The deployment utilizes HPE Aruba Networking Central for management. The network architect has configured a DHCP server to support Zero Touch Provisioning (ZTP). However, during the initial rollout, the APs obtain IP addresses but fail to appear in the Central 'Device Inventory'. The firewall team confirms that HTTPS traffic is allowed. Which specific DHCP option must be verified to ensure the APs can resolve the Central URL correctly?

    Answer and explanation

    Correct answer: D

    For ZTP to function, the device must be able to resolve the URL 'device.arubanetworks.com' (or the specific regional URL). If the device gets an IP but cannot resolve the Central URL, it cannot check in. DHCP Option 6 provides the DNS server IP addresses necessary for this name resolution. While Option 43 and 60 are used for Controller discovery or specific vendor identification, DNS (Option 6) is fundamental for cloud discovery.

  2. Question 2

    Advanced

    Device Management and Onboarding · HPE Aruba Networking Central UI Groups

    You are designing a configuration hierarchy in HPE Aruba Networking Central for a multinational corporation with sites in New York, London, and Tokyo. The requirement is to have a global SSID configuration for 'Eduroam' but distinct RF profiles for each region due to regulatory domain differences. Which approach best utilizes Central's Group and Site architecture to minimize administrative overhead?

    Answer and explanation

    Correct answer: A

    In HPE Aruba Networking Central, configuration is primarily defined at the Group level. While it is possible to override some settings at the device level, creating separate groups for distinct regulatory domains or major RF differences is the standard best practice. This allows for specific RF profiles per region while maintaining the ability to replicate the SSID config (or use APIs to sync them). Central does not support a 'Global Group' inheritance model where a child group inherits an SSID but overrides the RF profile in the way suggested by other options.

  3. Question 3

    Intermediate

    Device Management and Onboarding · Sync devices' configuration with HPE Aruba Networking Central

    An engineer needs to replace a failed AOS-CX switch that is managed by HPE Aruba Networking Central. The new switch is the exact same model. Which workflow ensures the new switch receives the exact configuration of the failed unit with minimal manual intervention?

    Answer and explanation

    Correct answer: C

    HPE Aruba Networking Central provides a specific 'Replace Device' workflow. By selecting the faulty device and choosing 'Replace', you can map the old configuration, license, and group assignment to the new device's serial number/MAC. This ensures that not just the Group configuration, but also device-specific overrides and historical data associations (where applicable) are transferred or preserved.

  4. Question 4

    Intermediate

    Device Management and Onboarding · Zero Touch Provisioning (ZTP) and One Touch Provisioning (OTP)

    You are deploying a pair of Aruba 9004 Gateways at a branch site. The site has no local IT staff. You plan to use One Touch Provisioning (OTP). Which of the following statements correctly describes the OTP requirement for these gateways?

    Answer and explanation

    Correct answer: A

    OTP for gateways allows them to communicate with Central even if ZTP (DHCP/DNS) fails or is unavailable. It involves connecting a computer to the gateway's OOB console or specific port and pushing a basic configuration (uplink setup) to allow it to reach the cloud. This is often necessary when static IPs or PPPoE are required for the WAN link.

  5. Question 5

    Advanced

    Device Management and Onboarding · Manual provisioning

    A network administrator is creating a configuration template for AOS-CX switches in Central. They need to ensure that the hostname of each switch is dynamically set based on the device's properties defined in the variable file. Which syntax correctly represents the variable for hostname assignment?

    Answer and explanation

    Correct answer: C

    In HPE Aruba Networking Central templates for AOS-CX, variables are enclosed in percentage signs. For example, hostname %hostname% allows the system to replace %hostname% with the value specified in the uploaded variables CSV or JSON file for that specific device serial number.

  6. Question 6

    Intermediate

    Device Management and Onboarding · HPE Aruba Networking Central UI Groups

    When moving a pre-configured AP from a 'Test' UI group to a 'Production' UI group in HPE Aruba Networking Central, what happens to the AP's configuration?

    Answer and explanation

    Correct answer: D

    In Central, the Group is the source of truth for configuration. When a device is moved to a new group, it will synchronize with the new group's configuration. This typically involves a reboot for APs to apply the new settings (SSIDs, RF profiles, etc.), effectively overwriting the previous group's settings.
