HPE7-A01 Sample Questions & Answers
Managing and monitoring the WLAN carries the top share, ahead of configuring the mobility conductor and controller, implementing secure WLAN and gateway features, tuning wired infrastructure performance, and troubleshooting connectivity issues.

Configuring and Using the Mobility Conductor and Mobility Controller · Tunneled Node
A company is setting up a Tunneled Node environment to provide unified policy enforcement for both wired and wireless users. A user connects their laptop to an ArubaOS-CX switch port that is configured for user-based tunneling. What is the expected behavior for the user's traffic?
Show answer & explanation
Correct answer: C
In a user-based tunneling (Tunneled Node) setup, after successful authentication (typically 802.1X), the switch encapsulates all data traffic from the authenticated user into a GRE tunnel directed to a Mobility Controller. The controller then applies the user's assigned role and firewall policies before forwarding the traffic, thus unifying policy enforcement for wired and wireless clients.

Implementing and Operating Secure Wireless LAN Features · Gateway Security Features
What is the primary purpose of the 'Control Plane Security' feature on an Aruba Mobility Controller?
Show answer & explanation
Correct answer: B
Control Plane Security (CPSec) is designed to protect the control communications (PAPI) between Aruba APs and the Mobility Controller. When enabled, it uses certificates to mutually authenticate the AP and controller and then encrypts all subsequent control plane traffic. This prevents rogue APs from joining the network and protects management traffic from eavesdropping or tampering.

Configuring and Optimizing Network Performance · VSF Implementation
A network administrator needs to provide a Layer 3 default gateway on an ArubaOS-CX switch stack created with VSF. The gateway must be resilient to the failure of the VSF conductor. How should this be configured?
Show answer & explanation
Correct answer: B
A VSF stack operates as one virtual switch with a single control plane. A single SVI configured on the stack is therefore a resilient default gateway: if the conductor fails, the standby takes over the conductor role and the SVI stays up. No FHRP such as VRRP or Active Gateway (a VSX feature) is needed inside a VSF stack.

Managing and Monitoring the Wireless LAN (WLAN) · AirWave Management
A hospital is using the VisualRF tool within AirWave to monitor its wireless network. A nurse reports a coverage hole in a specific area of the oncology ward. What is the most effective way for a network administrator to validate and visualize this reported issue using VisualRF?
Show answer & explanation
Correct answer: A
VisualRF's core function is to visualize RF data on a floor plan. By generating a signal strength heatmap for the specific floor and ward, the administrator can visually identify areas of weak signal (coverage holes). This allows them to confirm the user's report and make informed decisions about adding, moving, or adjusting the power of nearby APs.

Configuring and Optimizing Network Performance · VSX and VSF Implementation
What is the command to create a checkpoint of the running configuration on an ArubaOS-CX switch with the name 'pre-maintenance'?
Show answer & explanation
Correct answer: C
The correct command syntax on ArubaOS-CX to save the current running configuration to a named checkpoint is
copy running-config checkpoint. This allows for easy rollback to a known good state. - Question 6Beginner
Managing and Monitoring the Wireless LAN (WLAN) · WLAN Design and Implementation
When planning an outdoor mesh network using Aruba APs, what is the primary function of the Mesh Portal AP (MPP)?
Show answer & explanation
Correct answer: C
In an Aruba mesh network, the Mesh Portal (MPP) is the AP that has a physical Ethernet connection to the wired network. It serves as the gateway for all other mesh APs (Mesh Points) to backhaul their traffic. All traffic from the wireless mesh ultimately flows through the MPP to reach the rest of the network.

Configuring and Optimizing Network Performance · VSX and VSF Implementation
A network architect is designing a high-availability solution for a large university campus using ArubaOS-CX switches. The core layer requires a redundant architecture that supports active-active forwarding, independent control planes for software upgrades without downtime, and synchronization of ARP and MAC tables. Which technology should the architect select and how should the Inter-Switch Link (ISL) be configured?
Show answer & explanation
Correct answer: B
VSX keeps an independent control plane on each switch and synchronizes MAC, ARP, LACP and other states over the Inter-Switch Link (ISL), which is normally a LAG that carries all VLANs plus the VSX synchronization traffic. Because the control planes are independent, the pair is upgraded one peer at a time (
vsx update-software, a live software upgrade with near-zero downtime) while the other peer keeps forwarding, and VSX LAGs give active-active forwarding. VSF and backplane stacking use a single control plane, and VRRP with MSTP blocks redundant links instead of forwarding active-active. - Question 8Intermediate
Configuring and Using the Mobility Conductor and Mobility Controller · Mobility Master Deployment
A network administrator is configuring an Aruba Mobility Conductor (MCR) to manage a hierarchy of controllers. The administrator wants to ensure that a specific WLAN configuration is applied only to the controllers located in the 'West-Coast' branch office, while maintaining global settings for other parameters. Where should this WLAN profile be defined in the configuration hierarchy?
Show answer & explanation
Correct answer: C
In ArubaOS 8 architecture, configurations should be applied at the most specific group level required. Creating a dedicated group (e.g., /md/West-Coast) allows specific settings like the WLAN profile to be applied only to those devices, while they still inherit global settings from the /md node.
