Comprehensive and Detailed Explanation From Exact Extract of HPE Aruba Networking Switching:

When an AOS-10 gateway is onboarded into Aruba Central using the Full-Setup method, a local admin password is defined during the setup wizard on the gateway itself. Later, when the gateway joins an existing Aruba Central group, the group-level configuration (which includes the admin password defined for that group) is automatically pushed down to all devices in that group for configuration consistency.

However, if the password defined during full-setup is different from the admin password defined in the Aruba Central group, the synchronization process can cause a mismatch between the local device password and the one expected by Central. This mismatch prevents remote console login from working properly because Aruba Central attempts to authenticate to the gateway using the group-level admin credentials, not the local credentials from full-setup.

Exact Extract from HPE Aruba Networking Switching and Aruba Central Configuration Documents:

“During onboarding, the admin password configured at the group level in Aruba Central is applied to all devices in the group. If a device is added using full-setup with a different password, it may fail Central-initiated authentication functions such as remote console.”

“When gateways are provisioned using the full-setup workflow, the local administrator password must match the group-level administrator credentials in Aruba Central to allow remote console and CLI access through Central.”

Therefore, the issue arises because the full-setup password for the gateway does not match the group admin password defined in Aruba Central, resulting in the ‘incorrect password’ error when attempting to access the gateway remotely through Central.

Why the Other Options Are Incorrect:

A. The full-setup admin password is valid for remote access; there is no separate configuration option that “allows” or “disallows” remote console use.

“Remote console access uses the same admin account configured for device login; there is no additional enablement required.”

B. Aruba Central admin passwords do not expire by default. Group-level admin credentials are persistent configuration items, not time-based credentials.

“Local and group administrator passwords are static until manually changed.”

C. There is no “global Aruba Central admin password” used to authenticate to devices; authentication is performed using per-group or per-device credentials configured in Central.

“Each Aruba Central group maintains its own admin credentials that are propagated to member devices; there is no single global password for all groups.”

The Modulation and Coding Scheme (MCS) used by wireless stations is directly affected by the signal-to-noise ratio (SNR) and the frequency band. Higher SNR can lead to higher MCS values, which means better data rates. The frequency band can affect MCS due to different channel characteristics, such as the presence of interference and propagation properties, which are factors in determining data rates.

The Aruba AP-615 is a tri-band Wi-Fi 6E access point, capable of operating on the 2.4 GHz, 5 GHz, and 6 GHz bands. However, in the default configuration, Aruba AP-615 radios operate in dual-band mode (2.4 GHz and 5 GHz).

The 6 GHz radio (the “E” band for Wi-Fi 6E) remains disabled by default until explicitly enabled by configuration through the ArubaOS or Aruba Central interface.

According to the Aruba Access Point Configuration Guide and Wi-Fi 6E Deployment Guide:

“Tri-band APs such as the AP-615 support operation in 2.4GHz, 5GHz, and 6GHz frequency bands. By default, the AP operates in dual-band mode (2.4GHz and 5GHz). The 6GHz band must be explicitly enabled by configuring the radio profile to tri-band mode.”

Thus, when a tri-band SSID is created without explicitly modifying the radio band configuration, the AP-615 continues to use 2.4GHz and 5GHz by default.

Option Analysis:

A. Incorrect – The 6GHz radio is not enabled by default.

B. Correct – Default operation is on the 2.4GHz and 5GHz bands.

C. Incorrect – 6GHz is only enabled through manual configuration.

D. Incorrect – While partially true, the question specifies default tri-band SSID behavior, which defaults to 2.4GHz and 5GHz.

The correct address for the ClearPass Guest should match the FQDN of the HTTPS certificate installed on the device, which is often the FQDN of the vendor's product. This ensures secure and proper redirection to the captive portal during the authentication process. The FQDN should be entered in the Address field for ClearPass Guest configuration.

Comprehensive and Detailed Explanation From Exact Extract of HPE Aruba Networking Switching:

The requirement in this question is to allow IT staff to provision unique pre-shared keys (PSKs) for each IoT device on a single SSID, ensuring that one device’s PSK cannot be used by another. This is the definition of Multi-Pre-Shared Key (MPSK) functionality.

HPE Aruba Networking supports three main MPSK deployment methods:

MPSK Local – Keys are defined locally on the AP or gateway; no external integration.

MPSK with ClearPass – Keys are managed and validated via ClearPass Policy Manager.

MPSK with Cloud Authentication – Keys are generated, stored, and managed natively through Aruba Central Cloud Authentication.

In this scenario, the IT Helpdesk wants a simplified, cloud-based method to generate and manage per-device unique PSKs without needing a ClearPass deployment. This aligns directly with MPSK AES with HPE Aruba Networking Central Cloud Authentication.

Exact Extract from HPE Aruba Networking Switching and Central Documentation:

“MPSK with Cloud Authentication allows administrators to configure a single SSID where each device is assigned a unique PSK. The PSKs are securely stored and validated using Aruba Central’s cloud-based authentication service.”

“Each PSK is tied to a specific client identity. If another device attempts to connect using the same PSK, the authentication will fail.”

“This method simplifies onboarding of IoT and headless devices while maintaining security equivalent to 802.1X.”

Thus, the correct recommendation is MPSK AES with Aruba Central Cloud Authentication, which fully supports per-device key uniqueness, centralized management, and cloud-based authentication—ideal for IoT device onboarding.

Why the Other Options Are Incorrect:

A. MPSK AES with ClearPass:Valid and secure, but requires an on-prem ClearPass Policy Manager deployment. The question specifies a simpler method for IT Helpdesk to manage keys directly, which Cloud Authentication provides natively.

“ClearPass MPSK requires policy manager integration; Aruba Central Cloud Authentication provides a simpler cloud-native alternative.”

C. MPSK Local:Suitable for small static environments, but not scalable and requires manual key creation on the AP or gateway. Does not allow IT staff to easily generate new keys per device via Central.

“MPSK Local does not support centralized lifecycle management or key revocation.”

D. MPSK AES with MAC Auth:MPSK already handles per-device authentication via unique keys; MAC authentication is unnecessary and less secure.

“MAC authentication is an alternate method for non-802.1X devices but is not required with MPSK.”

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.”

In OSPF, the "EXSTART/DR" state indicates that the routers are trying to establish an adjacency but are unable to progress. This can happen if the OSPF network type is incorrectly configured for the type of connection between the routers. Given that R1 and R2 are connected via a point-to-point link (as suggested by the /31 subnet), setting the network type to point-to-point on both routers will remove the need for DR/BDR election, which is unnecessary on a point-to-point link, and allow OSPF to progress past the "EXSTART" state and form a full adjacency.

Comprehensive and Detailed Explanation From Exact Extract of HPE Aruba Networking Switching:

When using Downloadable User Roles (DUR) with HPE Aruba Networking ClearPass, the Aruba device (AP, gateway, or switch) must authenticate to ClearPass to retrieve and install the user role that ClearPass sends dynamically. This process differs from normal RADIUS authentication, where only the user credentials are verified.

In Aruba Central, when you configure an authentication server (ClearPass) and enable Downloadable Roles, the system requires CPPM Username and CPPM Password fields. These credentials are specifically used by the Aruba device to establish a secure HTTPS (TLS) session to the ClearPass server for DUR retrieval.

If the CPPM Username or CPPM Password values are missing, incorrect, or not synchronized with the corresponding credentials defined on ClearPass, the device will fail to authenticate to ClearPass for DUR retrieval. This results in RADIUS authentication succeeding (because LUR is still functioning), but the DUR cannot be downloaded.

Exact Extract from HPE Aruba Networking Switching and ClearPass Configuration Guides:

“When Downloadable User Roles are enabled, the Aruba device must authenticate with ClearPass using configured credentials. The device uses the CPPM Username and Password for HTTPS-based role retrieval. If the credentials are not defined or are invalid, role download will fail even if RADIUS authentication succeeds.”

“The CPPM Username and Password define the credentials the device uses to connect to ClearPass for downloadable role retrieval. These credentials must match the admin or API credentials configured on the ClearPass Policy Manager server.”

This explains why Local User Roles (LUR) work (standard RADIUS), but Downloadable User Roles (DUR) do not — the HTTPS/TLS authentication for DUR fails because the required credentials were not configured correctly.

Why the Other Options Are Incorrect:

A. Add a new Enforcement Policy of type "WEBAUTH" on ClearPass:WebAuth enforcement policies are unrelated to DUR. Downloadable User Roles are delivered using an Aruba Downloadable Role enforcement profile, not WebAuth.

“Downloadable roles are defined and enforced through the Aruba Downloadable Role profile type. WebAuth policies are used for captive portal authentication only.”

C. Uncheck the "Dynamic Authorization" checkbox:Dynamic Authorization (RFC 3576 or CoA) allows session reauthentication or role changes. Disabling this feature would not fix DUR, as DUR relies on CPPM credentials for HTTPS authentication.

“Dynamic Authorization (CoA) enables session updates but does not control role download authentication.”

D. Modify the shared secret on the switch using the 'radius-server host' command:This option applies to switch RADIUS configuration, not Aruba Central APs or gateways. The DUR process uses HTTPS with ClearPass credentials, not the RADIUS shared secret.

“The RADIUS shared secret is used for authentication requests, not for downloadable role retrieval. Downloadable roles require valid CPPM credentials.”

When configuring Virtual Switching Extension (VSX) in a campus topology for link aggregation across two aggregation switches, it is important to synchronize Multi-Chassis Link Aggregation Group (MC-LAG) interfaces. The command "vsx-sync mclag-interfaces" ensures that the state and configuration of MC-LAG interfaces are synchronized between the two VSX-linked switches, providing consistent link aggregation and preventing any loops or mismatched configurations that might occur if the interfaces were not in sync.

In VRRP (Virtual Router Redundancy Protocol), only one switch should be the primary (master) for a given virtual IP address, with the other switches being backups. If both switches are showing as active, it suggests a misconfiguration where both are set to act as the primary for the same VRRP group. The exhibits provided indicate that both switches believe they are the active or primary for the VRRP group, which is an incorrect configuration.
