NO.34 A user’s role should restrict access to internal resources but allow internet access. Which policy configuration enforces this?

Configure the default enforcement for the policy to allow-all

Add a rule to restrict internal access at the end of the policy

Add a rule to restrict internal access at the start of the policy

Aruba policies operate on a “first-match” principle, meaning the switch or gateway processes rules sequentially from top to bottom. To effectively restrict access to internal resources while allowing everything else (like the internet), the restrictive rule must be placed at the beginning of the policy. If the restriction were at the end, a more general “allow” rule might trigger first, inadvertently permitting access to the internal network before the “deny” rule is ever reached.
This ensures the security boundary is checked before any broader permissions are granted.

NO.35 You need to configure four uplinks between an AOS-CX access and aggregation switch. Which HPE Aruba Networking Central configuration method should you use?

Configure four individual access ports and disable spanning-tree

Create a LAG with LACP and bind four member interfaces

Assign each port to a different VLAN for load distribution

A Link Aggregation Group (LAG) with Link Aggregation Control Protocol (LACP) is the standard method for bundling multiple physical links into a single logical high-bandwidth connection. By binding the four member interfaces into a LAG, the switches treat the uplinks as one entity, which increases total available throughput and provides redundancy. LACP specifically ensures that both ends of the link are correctly configured and functional, preventing loops or traffic loss that could occur if individual ports were manually configured or if spanning-tree were simply disabled.

NO.36 You need to ensure APs broadcast a Guest SSID in the front desk area on every company site.
How can you perform that most efficiently?

Creating SSIDs at the global level and deleting them where they are not needed.

Assign APs to a device group and assign the WLAN profile to the device group.

Creating SSIDs on each AP (device level).

Device groups in HPE Aruba Networking Central serve as the primary container for configuration at scale. By assigning the relevant access points to a specific group and applying the WLAN profile at that group level, the Guest SSID is automatically pushed to all member devices regardless of their physical site. This centralized management approach ensures configuration consistency and eliminates the repetitive manual task of configuring each access point or site individually.

NO.37 When onboarding a new switch into Aruba Central, what identifier is commonly used?

MAC address and serial number

VLAN ID only

IP address only

Devices are typically onboarded using their serial number and MAC address, allowing Aruba Central to verify ownership and assign subscriptions.

NO.38 A retail stack must survive a member failure with minimal disruption. Which configuration in HPE Aruba Networking Central addresses this goal?

Create a VRF per switch for redundancy

VSF with proper member roles and link design

A VSX stack with two or more members and MC-LAG

A VSX-based design with multiple members and MC-LAG provides high availability by maintaining independent control planes while ensuring active-active forwarding. This allows traffic to continue flowing with minimal disruption if one stack member fails, making it suitable for retail environments requiring resilient redundancy.

NO.39 A guest SSID must isolate clients from internal networks. Which configuration achieves this?

Assign a guest access role with restrictive policy

Use a mixed SSID where guests are bridged and employees are tunneled to the gateway

Guest networks must belong to a separate VRF to ensure traffic isolation

Assigning a guest access role with a restrictive policy enforces client isolation and limits access to internal resources. This role-based policy control is the standard method in HPE Aruba Networking Central to ensure guest users are restricted to internet-only access while being blocked from internal networks.

NO.40 What is true about the Developer Hub portal?

API calls are actively changing the device’s configuration.

Developer Hub provides sample codes for APIs; no API calls are made from it.

API calls are for demonstration only.

The Developer Hub portal is designed to provide documentation, API references, and sample code examples to help developers understand how to interact with the platform. It does not execute API calls against live infrastructure, so it is used for learning and development purposes rather than performing actual configuration changes.

NO.41 What is the primary purpose of firmware compliance monitoring?

Track user authentication

Ensure devices run approved software versions

Configure wireless SSIDs

Firmware compliance helps organizations maintain security and operational consistency by ensuring devices are running approved firmware versions.

NO.42 Where can you view live throughput, and client counts per AP?

AP dashboard > Connectivity performance card.

Device Health dashboard.

RF Optimization tab.

The Connectivity performance card on the specific AP dashboard provides real-time telemetry data for that individual device. This view is designed to offer immediate visibility into operational metrics, displaying the current data transfer rates and the exact number of associated clients at any given moment. This allows administrators to monitor the live load and performance impact on a per-AP basis without navigating through global network reports.

NO.43 Which AI-powered feature helps identify the root cause of network issues?

Device Inventory

AIOps Insights

Faceplate View

AIOps Insights uses artificial intelligence and machine learning to analyze network telemetry, identify anomalies, and provide root-cause analysis recommendations.

NO.44 Which design ensures continuous WLAN coverage if an AP fails?

Deploy APs in overlapping coverage zones.

Create a custom ‘single channel’ RF profile.

Increase transmit power to maximum on all Aps.

Deploying Access Points with overlapping coverage zones (typically 15% to 20% overlap) is the fundamental principle of high-availability wireless design. If a single AP fails, the neighboring APs are positioned close enough to provide a usable signal to the area previously served by the failed device. This prevents “dead zones” and allows client devices to roam to a healthy AP without losing connectivity.

NO.45 A customer needs consistent port configuration (Speed, Duplex, PoE, STP) on all access switches. Which configuration approach uses HPE Aruba Networking Central’s intent-based model?

Apply a Global alias only without profile linkage

Configure interfaces for every switch individually

Create a Port Profile and assign it to applicable interfaces

Port Profiles in HPE Aruba Networking Central implement an intent-based configuration model that allows standardized settings (such as speed, duplex, PoE, and STP behavior) to be defined once and consistently applied across multiple access switch interfaces. This ensures uniform configuration while reducing manual per-device effort and configuration drift.

NO.46 AI Insights suggests overlapping channels on multiple APs. What is the most efficient corrective action?

Manually reconfigure all APs.

Review and apply the AI recommendation.

Disable Airmatch temporarily.

HPE Aruba Networking Central utilizes AI Insights to continuously monitor the network and identify performance bottlenecks like co-channel interference. When overlapping channels are detected, the system generates specific, validated recommendations to optimize the RF environment. Applying these AI-driven recommendations is the most efficient approach because it leverages automated analysis to resolve the conflict across multiple access points simultaneously, eliminating the need for time-consuming manual channel planning or individual device reconfiguration.

NO.47 Which dashboard widget displays the overall status of managed devices?

Health Card

Audit Log

Template Manager

The Health Card provides a summary of device status, connectivity, and operational health, helping administrators quickly assess network conditions.

NO.48 AOS10 shows “Auth Timeout” for several clients. What should you check first?

RADIUS server reachability and response time.

DNS records.

VLAN assignment.

“Auth Timeout” in AOS-10 indicates that authentication requests are not receiving timely responses from the authentication infrastructure. The first step is to verify RADIUS server reachability and response time to confirm whether delays or connectivity issues are causing authentication timeouts.

NO.49 Which HPE Aruba Networking Central feature provides RF management?

Adaptive Radio Management (ARM)

Airmatch

ClientMatch

In AOS-10 environments managed by HPE Aruba Networking Central, AirMatch functions as the automated RF optimization service. It collects telemetry from all access points across the network to calculate and deploy the most efficient channel assignments, channel widths, and transmit power levels. This centralized approach allows the system to analyze the entire RF neighborhood simultaneously, minimizing interference and maximizing capacity more effectively than older, localized radio management methods.
