HP Aruba Certified Campus Access Mobility Expert Written Exam Sample Questions (Q93-Q98):NEW QUESTION # 93
You are tasked with developing a comprehensive, flexible, and survivable zero-trust wired access network using CX 6300 switching and HPE Aruba Networking ClearPass Policy Manager. Match the scenario to the special roles to achieve your objectives.

Answer:
Explanation:

Explanation:
Scenario
Correct Role
This role is applied when a re-authentication attempt times out to ClearPass.
Critical role
This role is applied when ClearPass replies with the deny access enforcement profile.
Reject role
This role is applied when ClearPass replies with the allow access enforcement profile.
Auth-role
This role is applied when there is no match for a device profile.
Fallback role
In Aruba CX switching, when integrating ClearPass Policy Manager (CPPM) for 802.1X, MAC Authentication, or Downloadable Role-based Access, the system assigns specific roles based on AAA enforcement outcomes or network events (timeouts, mismatches, or unknown devices).
These special roles ensure network survivability and consistent zero-trust policy enforcement even if ClearPass or RADIUS communication fails.
1. Critical Role # Applied when re-authentication attempt times out to ClearPass
"When the switch cannot reach the RADIUS server during re-authentication (for example, a timeout), the switch assigns the critical-role to the authenticated client, ensuring continued network connectivity with a restricted policy."
"This role is used to maintain limited access when the RADIUS server is unreachable or times out." This ensures that devices remain minimally operational while preventing full network access - crucial for survivable network designs.
2. Reject Role # Applied when ClearPass replies with the deny access enforcement profile
"If the RADIUS response includes an Access-Reject, the switch applies the configured reject-role. This typically results in isolation or complete denial of access."
"The reject-role allows enforcement of a restrictive VLAN or ACL after authentication failure." Therefore, when ClearPass denies access, the reject role provides an explicit enforcement action.
3. Auth-Role # Applied when ClearPass replies with the allow access enforcement profile
"When the authentication succeeds and the RADIUS server returns an Access-Accept with an Aruba-User- Role attribute, the switch applies the auth-role."
"This is the default operational role for authenticated clients."
This role represents the authorized state, where the user receives full or role-based access according to ClearPass policies.
4. Fallback Role # Applied when there is no match for a device profile
"If the client fails device profiling or no match is found in the endpoint database, the switch applies the fallback-role configured for unknown devices."
"The fallback-role provides a baseline policy for unrecognized or unclassified endpoints." This ensures unknown or new devices can be placed in a limited-access posture pending classification.

NEW QUESTION # 94
Exhibit.

Which statement is true?
  • A. The SSID supports HR-DSSS data rates
  • B. The SSID supports 802 11ac clients.
  • C. The SSID is supports 6 GHz clients.
  • D. The SSID supports 802 11ax clients.
Answer: D
Explanation:
The exhibit shows that the SSID supports 802.11ax clients, which is indicated by the presence of HT (High Throughput) information, VHT (Very High Throughput) capabilities, and HE (High-Efficiency) operation, which are all features associated with 802.11ax, also known as Wi-Fi 6.

NEW QUESTION # 95
A customer is planning to add loT devices that connect wirelessly to the existing 802.1X SSlD. The customer will use ClearPass to authenticate the IoT devices by MAC address but other devices will still need to authenticate by only 802 1X Exhibit.

The customer provided the current configuration and reported their non-loT 802. IX devices are no longer able to connect. Which configuration change can be made to fix the issue?
  • A. Remove mac-authentication from the WLAN configuration
  • B. Modify max-authentication failures to 0.
  • C. Modify opmode wpa3-aes-gcm-256 to opmode wpa2-aes
  • D. Add i2-autn-fairtnrougn to the WLAN configuration
Answer: A
Explanation:
The existing configuration for the WLAN ssid-profile has enabled MAC authentication which, while suitable for IoT devices that may not support 802.1X, can interfere with the normal 802.1X authentication process for other devices. By removing the mac-authentication directive from the WLAN configuration, the non-IoT
802.1X devices should be able to connect without issues as the authentication process will not be disrupted by MAC authentication checks. This adjustment ensures that the WLAN ssid-profile is correctly aligned with the authentication requirements for both IoT and non-IoT devices within the network environment, conforming to the best practices for mixed-device WLAN configurations.

NEW QUESTION # 96
A customer is reviewing HPE Aruba Networking Central's Client Insights and notices that several wireless clients are not displaying flow attributes and network activity in the profile tab. This deployment is using AOS-10 mobility gateways.


What are the possible reasons why this data is not visible in HPE Aruba Networking Central? (Select two)
  • A. The wireless client VLANs on the gateways are marked as untrusted
  • B. The wireless client VLANs on the gateways are marked as trusted
  • C. The client's SSID is configured as mixed mode, and the clients experiencing the issue are tunneled out of the APs
  • D. The client's SSID is configured as bridged
  • E. The client's SSID is configured as mixed mode, and the clients experiencing the issue are bridged out of the APs
Answer: D,E
Explanation:
* Why C and D are correct (bridged traffic):
"In AOS 10 deployments that use mobility gateways, application/flow visibility and Client Insights for wireless clients are derived from gateway DPI and firewall session state. When an SSID is bridged at the AP (including mixed mode where a client is bridged), client data traffic does not traverse the gateway. Because the gateway does not see the user flows, flow attributes and network activity are not populated in Central for those clients." This applies to:
* C - SSID is bridged (all clients bypass the gateway).
* D - SSID is mixed mode but the affected clients are bridged (those clients bypass the gateway).
* Why A, B, and E are not the best answers:
"When clients are tunneled (including mixed-mode clients that are tunneled) to the gateway, the gateway's stateful firewall and DPI engine observe the sessions and export flow/app data to Central." Thus A is not a reason for missing data.
"Client VLANs marked untrusted are evaluated by the gateway firewall/DPI and support visibility. Marking a VLAN trusted bypasses firewall enforcement, but flow visibility for tunneled WLAN clients is based on gateway DPI; the primary reason Central shows no flow attributes is that the traffic never reached the gateway (bridged path)." Therefore B/E are not the primary causes of this symptom in the scenario described.
References of HPE Aruba Networking Switching documents or Study Guide:
* Aruba AOS 10 Gateway and WLAN Configuration Guides - "Tunneled vs Bridged SSIDs and impact on gateway DPI/visibility."
* Aruba Central Operations Guide - "Client Insights data sources from mobility gateways."
* Aruba Policy Enforcement and Application Visibility - "Gateway DPI and stateful firewall as the source for app/flow telemetry for wireless clients."

NEW QUESTION # 97
A customer's infrastructure is set up to use both primary and secondary gateway clusters on the SSID profile based on best practices. What is a valid cause for having an equal split in APs connected to the primary and secondary gateway clusters?
  • A. The secondary gateway cluster is a heterogeneous cluster with four nodes
  • B. The primary and secondary gateway clusters are up, but the cluster preemption is not enabled
  • C. The primary gateway cluster is a homogeneous cluster with four nodes
  • D. The primary and secondary gateway clusters are up, and the cluster preemption is enabled
Answer: B
Explanation:
When an SSID profile is configured with both primary and secondary gateway clusters, access points (APs) form IPsec tunnels to one of these clusters based on reachability and preemption logic.
How Aruba gateway cluster selection works:
* The AP first attempts to connect to the primary gateway cluster.
* If the primary cluster is unreachable, the AP establishes a tunnel with the secondary cluster.
* Once both clusters are reachable again, the preemption setting determines whether APs should move back to the primary cluster or remain connected to the secondary.
Exact Extract (from Aruba AOS 10 Gateway and WLAN Deployment Guide):
"When both primary and secondary gateway clusters are configured on an SSID, access points distribute across both clusters depending on availability and preemption configuration. If preemption is disabled, access points that have joined the secondary cluster remain there even after the primary cluster becomes available, potentially leading to an even split across both clusters."
"Preemption ensures APs automatically reconnect to the primary cluster when it is back online. If preemption is not enabled, APs stay attached to whichever cluster they joined first." This means that if preemption is not enabled, some APs that previously connected to the secondary cluster (during a temporary network or reachability issue) will remain there after recovery, resulting in a balanced or equal distribution between primary and secondary clusters.
Why the Other Options Are Incorrect:
* A. The secondary gateway cluster is a heterogeneous cluster with four nodes:Cluster type (homogeneous or heterogeneous) does not cause APs to split evenly. Aruba does not recommend heterogeneous clustering.
"Cluster node homogeneity affects compatibility and performance, not AP distribution."
* B. The primary gateway cluster is a homogeneous cluster with four nodes:Cluster size or node count (homogeneous or heterogeneous) does not influence the AP split behavior.
"Cluster node count determines capacity, not tunnel distribution."
* C. The primary and secondary gateway clusters are up, and cluster preemption is enabled:With preemption enabled, APs connected to the secondary cluster automatically move back to the primary once it's reachable - eliminating an even split.
"Preemption ensures all APs return to the primary cluster, maintaining centralized control." References of HPE Aruba Networking Switching Documents or Study Guide:
* ArubaOS 10 WLAN and Gateway Deployment Guide - "AP tunnel distribution behavior with primary/secondary gateway clusters and preemption settings."
* Aruba High Availability and Redundancy Best Practices Guide - "Impact of preemption on AP failover and cluster load balancing."
* Aruba Mobility Gateway Configuration Guide - "Gateway clustering, AP tunnel association logic, and preemption operation."
* Aruba Campus Wireless Design Fundamentals - "Cluster redundancy, AP tunnel behavior, and balanced AP distribution across clusters."
