The reason is that ClearPass OnBoard is a tool that allows you to enroll Mac computers into a ClearPass Policy Manager site using an Apple MDM push certificate. This certificate can be obtained from Apple or from a third-party PKI provider.

Apple Configurator is a tool that allows you to configure and deploy Mac computers using a GPO. This tool can also be used to enroll Mac computers into a ClearPass Policy Manager site using an Apple MDM push certificate.

The default value for config-revision on Core-1 is 0. Config-revision is a parameter that indicates the configuration version of a VSX pair. It is used to synchronize the configuration between the VSX peers and to detect any configuration mismatch. The config-revision value is set to 0 by default on both VSX peers and is incremented by 1 every time a configuration change is made on either peer. The other options are incorrect because they do not reflect the default value of config-revision.

The capability that enables plug-and-play provisioning of access points in an HPE Aruba network is the UCC Service. The UCC Service is a cloud-based service that allows the access points to automatically discover and connect to the Aruba Central management platform without any manual intervention. The UCC Service also provides zero-touch configuration, firmware updates, and monitoring for the access points 1 .

The other options are incorrect because:

B. LLDP-MED: LLDP-MED is a protocol that enhances the interoperability between network devices and IP phones. It does not enable plug-and-play provisioning of access points 2 .

C. SRTP: SRTP is a protocol that provides encryption and authentication for voice and video traffic. It does not enable plug-and-play provisioning of access points 3 .

D. CSMA: CSMA is a protocol that regulates how devices share a common medium, such as a wireless channel. It does not enable plug-and-play provisioning of access points.

This is the most likely cause of the issue where the access points in a Microbranch group are online in Aruba Central, but no VPN tunnels are forming. A Microbranch group is a group that contains both APs and Gateways and allows them to form VPN tunnels for secure communication. The VPN tunnels use GRE (Generic Routing Encapsulation) as the encapsulation protocol and IPSec as the encryption protocol. If there is a firewall blocking GRE traffic between the AP and the gateway, the VPN tunnels cannot be established. The other options are incorrect because they either do not affect the VPN tunnel formation or do not apply to a Microbranch group.

The component that is used by the Aruba Network Analytics Engine (NAE) is D. Current State Database.

The Current State Database is a database that stores the configuration and state information of the switch, such as interfaces, VLANs, routing protocols, statistics, and more. The NAE can access this database through the AOS-CX REST API and monitor the values of any data point using monitors. The NAE can also track the history of the values in a time-series database and correlate them with network events or configuration changes 1 . The Current State Database provides NAE with direct visibility into the entire current state of the device, which enables intelligent troubleshooting and automation of network tasks 1 .

The other options are incorrect because:

A. JSON-based scripts: JSON is a data format that is used to exchange information between applications. It is not a scripting language that can be used by NAE. NAE scripts are written in Python, which is a popular and powerful programming language 1 .

B. Lisp-based agents: Lisp is a family of programming languages that are mainly used for artificial intelligence and functional programming. It is not a language that can be used by NAE. NAE agents are instances of scripts that run on the switch and collect relevant network information and trigger alerts or actions 1 .

C. Ruby-based scripts: Ruby is a general-purpose programming language that is known for its expressiveness and elegance. It is not a language that can be used by NAE. NAE scripts are written in Python, which is a popular and powerful programming language 1 .

This is the appropriate solution for this scenario where wireless 802.1X authentication will be against a RADIUS server in the cloud and the security team is concerned that the traffic between the AP and the RADIUS server will be exposed. RadSec, also known as RADIUS over TLS, is a protocol that provides encryption and authentication for RADIUS traffic over TCP and TLS. RadSec can be configured on both the AP and the RADIUS server to establish a secure tunnel for exchanging RADIUS packets. The other options are incorrect because they either do not provide encryption or authentication for RADIUS traffic or do not involve RadSec.

Active gateway is a first hop redundancy protocol that eliminates a single point of failure. The active gateway feature is used to increase the availability of the default gateway servicing hosts on the same subnet. An active gateway improves the reliability and performance of the host network by enabling a virtual router to act as the default gateway for that network.  If you have enabled active gateway, VRRP is not required 3 . Active gateway is similar to VRRP in that routed traffic from the VSX node is sourced from the switch interface MAC and not the virtual MAC address (VMAC). Each active gateway sends a periodic broadcast hello packet to avoid VMAC aging on the access switches.  The switch views the active gateway IP as a self IP address 3 .  Active gateway is preferable over VRRP because with VRRP traffic is still pushed over the ISL link, resulting in latency in the network 3 . Therefore, VRRP and active gateway are mutually exclusive on a VLAN, and answer A is correct.

The correct answers are C and D.

MPSK (Multi Pre-Shared Key) is a feature that allows multiple PSKs to be used on a single SSID, providing device-specific or group-specific passphrases for enhanced security and deployment flexibility for headless IoT devices 1 . MPSK requires MAC authentication against a ClearPass Policy Manager server, which returns the encrypted passphrase for the device in a RADIUS VSA 2 . ClearPass Policy Manager is a platform that provides role- and device-based network access control for any user across any wired, wireless and VPN infrastructure 3 . ClearPass Policy Manager can also use device profiling and posture assessment to assign roles based on device fingerprint information 4 .

MPSK Local is a variant of MPSK that allows the user to configure up to 24 PSKs per SSID locally on the device, without requiring ClearPass Policy Manager 5 . MPSK Local can be combined with EAP-TLS (Extensible Authentication Protocol-Transport Layer Security), which is a secure authentication method that uses certificates to encrypt the wireless traffic between the IoT devices and the access points 6 . EAP-TLS can also use device certificates to perform role-based access control 6 .

Therefore, both ClearPass Policy Manager and MPSK Local with EAP-TLS can meet the customer’s requirements for wireless authentication, encryption, unique passphrase, and role-based access for their IoT devices.

MPSK and an internal RADIUS server is not a valid solution, because MPSK does not support internal RADIUS servers and requires ClearPass Policy Manager 7 8 9 . MPSK Local with MAC Authentication is not a valid solution, because MAC Authentication does not encrypt the wireless traffic or use fingerprint information for role-based access 2 . Local User Derivation Rules are not a valid solution, because they do not provide unique passphrase per device or use fingerprint information for role-based access 10 11 12 .
