The primary and secondary gateway clusters are up. and the cluster preemption is enabled

The secondary gateway cluster is a homogeneous cluster with six nodes.

The primary and secondary gateway clusters are up. but the cluster preemption Is not enabled

Q61. A customer’s infrastructure is set up to use both primary and secondary gateway clusters on the SSID profile based on best practices. Why do they have an equal split of their 260 APs across the primary and secondary gateway clusters?

The primary gateway cluster is up, but some APs cannot reach the secondary gateway cluster. These APs would connect to the secondary gateway cluster

The secondary gateway cluster is homogeneous

The secondary gateway cluster is heterogeneous

The primary gateway cluster is up, but some APs cannot reach the primary gateway cluster. These APs would connect to the secondary gateway cluster

Comprehensive and Detailed Explanation From Exact Extract of HPE Aruba Networking Switching:
In AOS-10 wireless deployments, HPE Aruba Networking supports the configuration of Primary and Secondary Gateway Clusters in the SSID profile to ensure high availability, redundancy, and load distribution. This configuration follows Aruba’s gateway clustering best practices, where access points (APs) attempt to establish tunnels with their Primary Gateway Cluster first. If the AP cannot reach the primary cluster (due to reachability, latency, or network topology), it automatically connects to the Secondary Gateway Cluster.
When both gateway clusters are active and reachable but some APs cannot reach the primary cluster-for example, due to Layer 3 routing, firewall restrictions, or network segmentation-those APs will associate with the secondary cluster instead. This results in an approximately equal split of APs across both clusters, even though the primary cluster is operational.
Exact Extract from HPE Aruba Networking Switching and AOS-10 Gateway Documentation:
“Access Points attempt to form tunnels with the Primary Gateway Cluster first. If the primary cluster is unreachable or fails to respond within the defined timeout, the AP establishes a tunnel with the Secondary Gateway Cluster.”
“When the primary and secondary gateway clusters are both up but APs are distributed across separate routed networks or VLANs, APs may select the gateway cluster that is most reachable at that time, resulting in an even or partial split of AP distribution.”
“This is expected behavior when APs in different subnets cannot reach the same primary cluster due to network topology. The secondary cluster provides redundancy and connectivity continuity.” Therefore, the equal split of 260 APs is explained by the fact that while the primary cluster is active, a subset of APs cannot reach it due to routing or segmentation and thus join the secondary cluster-this behavior aligns with Aruba’s gateway redundancy mechanism.
Why the Other Options Are Incorrect:
* A. The statement reverses the cause: APs that cannot reach the primary connect to the secondary- not the other way around. The secondary cluster’s reachability does not affect AP selection when the primary is available and reachable.
“APs first attempt the primary cluster; only failure to reach it triggers fallback to secondary.”
* B. Secondary cluster is homogeneous:Cluster homogeneity refers to identical hardware/software versions between gateways; it does not influence AP distribution or equal load split.
“Homogeneity is a software version consideration, not an AP load-balancing factor.”
* C. Secondary cluster is heterogeneous:Heterogeneity (mixed hardware types) is unsupported or discouraged; it does not cause AP distribution behavior.
“Heterogeneous gateway clusters are not a cause of AP distribution variation; cluster type does not dictate AP split.” References of HPE Aruba Networking Switching Documents or Study Guide:
* ArubaOS 10 Gateway and AP Deployment Guide – “Primary and Secondary Gateway Cluster Configuration and AP Association Logic.”
* Aruba High Availability and Clustering Best Practices Guide – “Gateway Cluster Failover, Redundancy, and AP Selection.”
* Aruba Central Cloud Management and Monitoring Guide – “SSID Profile Configuration: Primary and Secondary Gateway Clusters.”
* Aruba Campus Wireless Design Guide (AOS 10.x) – “Cluster Reachability, Redundancy, and Role Propagation Across Gateways.”

Q62. A customer has deployed an AOS 10 mobility gateway cluster consisting of three controllers at a single site The WLAN is configured to tunnel wireless device traffic to the AOS 10 mobility cluster The clients are authenticated by ClearPass using WPA3-Enterprise (opmode wpa3-aes-ccm-128). The security team has requested the ability to force a wireless device to reauthenticate using ClearPass.
Which steps are required to ensure ClearPass can consistently initiate a change of authorization against an AOS 10 mobility cluster, including during gateway failover scenarios? (Select two)

set cluster mode to Auto Site under High Availability – Cluster configuration

modify WLAN – SSID – VLAN – Mode Configuration

enable manual cluster configuration under High Availability – Cluster Configuration

enable Dynamic Authorization CoA under High Availability – Cluster Configuration

modify NAS IPv4 address under Security – Advanced – RADIUS Client

Q63. 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?

The secondary gateway cluster is a heterogeneous cluster with four nodes

The primary gateway cluster is a homogeneous cluster with four nodes

The primary and secondary gateway clusters are up, and the cluster preemption is enabled

The primary and secondary gateway clusters are up, but the cluster preemption is not enabled

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.”

Q73. A network administrator wants to configure an 802.1X supplicant for a wireless network that includes the following:
* AES encryption
* EAP-MSCHAPv2-based user and machine authentication
* Validation of server certificate in Microsoft Windows 10
The network administrator creates a WLAN profile and selects the Change connection settings option. Then the network administrator changes the security type to Microsoft: Protected EAP (PEAP) and enables user and machine authentication under Additional Settings.
What must the network administrator do next to accomplish the task? (Select two)

Enable server certificate validation

Enable user authentication

EAP-TLS-based user and machine authentication

Change default RC4 encryption for AES

Comprehensive and Detailed Explanation From Exact Extract of HPE Aruba Networking Switching:
When configuring an 802.1X supplicant in Microsoft Windows for EAP-PEAP (Protected EAP) using EAP-MSCHAPv2, both user and machine credentials can be used for authentication. The network administrator has already enabled user and machine authentication under Additional Settings, but to meet the stated requirements (AES encryption and server certificate validation), two critical steps remain:
* Enable server certificate validationThis ensures the client validates the identity of the RADIUS server (such as Aruba ClearPass or another authentication server) to prevent man-in-the-middle attacks.
It satisfies the requirement for “validation of server certificate in Windows 10”.
Exact Extract:
“For EAP-PEAP with EAP-MSCHAPv2, select ‘Validate server certificate’ to ensure the client trusts the authentication server’s identity. The server certificate must be signed by a CA trusted by the client.”
* Enable user authenticationWhile both user and machine authentication are possible, user authentication must be explicitly enabled so that credentials (domain or local user) are sent after machine authentication completes. This enables the full EAP-MSCHAPv2-based user and machine authentication process.
Exact Extract:
“In EAP-PEAP properties, ensure ‘Enable user authentication’ is selected to authenticate both the workstation and logged-on user credentials when using EAP-MSCHAPv2.” Additionally, Windows 10 uses AES encryption automatically when WPA2/WPA3-Enterprise is configured, fulfilling requirement (1). RC4 encryption is not applicable because AES is the default cipher for WPA2 Enterprise networks.
Why the Other Options Are Incorrect:
* C. EAP-TLS-based user and machine authentication:The question specifies EAP-MSCHAPv2, not EAP-TLS. EAP-TLS uses digital certificates for mutual authentication, while PEAP with EAP- MSCHAPv2 uses username and password-based credentials.
“EAP-TLS is certificate-based; PEAP-MSCHAPv2 uses password-based authentication.”
* D. Change default RC4 encryption for AES:RC4 is used in older WPA or TKIP security types. When using WPA2-Enterprise, AES is automatically selected and cannot be manually overridden.
“WPA2-Enterprise (802.1X) uses AES-CCMP encryption; RC4/TKIP is not applicable to modern configurations.” References of HPE Aruba Networking Switching Documents or Study Guide:
* Aruba Secure Connectivity and Authentication Guide (AOS-10) – “Configuring Windows 802.1X Supplicant for PEAP-MSCHAPv2.”
