HPE4-A51 sample questions

Question 1

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?

Accepted Answer

Option 6 (Domain Name Server)

Answer

Option 60 (Vendor Class Identifier)

Answer

Option 43 (Vendor Specific Information)

Answer

Option 15 (Domain Name)

Question 2

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?

Accepted Answer

Create three separate UI Groups (NY, LON, TYO), configure the Eduroam SSID identically in each, and apply specific RF profiles to each group.

Answer

Create a single Global UI Group with the Eduroam SSID and use Site-level overrides for the RF profiles.

Answer

Create a single Global UI Group and use Label-based configuration to apply different RF profiles based on device tags.

Answer

Create a Template Group for the APs and use variable interpolation for the Regulatory Domain setting only.

Question 3

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?

Accepted Answer

Use the 'Replace Device' workflow in the Central Device Inventory, select the down device, and map it to the new device serial number.

Answer

Add the new switch to the Device Inventory, assign it to the same Group as the old switch, and Central will automatically push the group configuration.

Answer

Manually copy the configuration from the Audit Trail of the old switch and paste it into the console of the new switch before connecting it to the network.

Answer

De-provision the old switch, wait 15 minutes for the license to release, then provision the new switch and restore the configuration from a local backup.

Question 4

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?

Accepted Answer

True

Answer

False

Question 5

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?

Accepted Answer

%hostname%

Answer

${hostname}

Answer

Answer

#hostname#

Question 6

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?

Accepted Answer

The AP is automatically rebooted and adopts the configuration defined in the 'Production' group, losing previous group-level settings.

Answer

The AP retains its 'Test' configuration as local overrides until manually cleared.

Answer

The AP merges the 'Test' configuration with the 'Production' configuration.

Answer

The AP enters a 'Config Mismatch' state and requires manual intervention to accept the new group profile.
