The default management role that should have been assigned for the user is B. operators.

The operators user role is a predefined role that allows users to view nonsensitive configuration information on the switch, such as interfaces,

VLANs, routing protocols, statistics, and more. The operators user role has a privilege level of 1, which is the lowest level of access on

the switch 1 .

The administrators user role is a predefined role that has full access to all switch configuration information and all REST API methods. This role is more than what the Director of Security requires 1 .

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 .

Encryption is a feature supported by SNMPv3 that provides an advantage over SNMPv2c. Encryption protects the confidentiality and integrity of SNMP messages by encrypting them with a secret key. SNMPv2c does not support encryption and relies on community strings for authentication and authorization, which are transmitted in clear text and can be easily intercepted or spoofed. Transport mapping, community strings, and GetBulk are features that are common to both SNMPv2c and SNMPv3.

These are the correct requirements to ensure that WMM (Wi-Fi Multimedia) is working effectively. WMM is a standard that provides quality of service (QoS) for wireless networks by prioritizing traffic into four categories: voice, video, best effort, and background. To use WMM, both the APs and the controller must be Wi-Fi CERTIFIED for WMM, which means they have passed interoperability tests and comply with the standard. WMM must also be enabled on the APs and the controller, which is usually the default setting. The client device must also be Wi-Fi CERTIFIED for WMM and configured for WMM marking, which means it can tag its traffic with the appropriate priority level based on the application type. The other options are incorrect because they are either not related to WMM or not required for WMM to work.

Opportunistic Wireless Encryption (OWE) is a feature that provides encryption for open wireless networks without requiring authentication. OWE uses an enhanced version of the 4-way handshake to establish a pairwise key between the client and the AP, which is then used to encrypt the wireless traffic using WPA2 or WPA3 protocols. OWE can be used for visitor networks where encryption is needed but authentication is not required. References: https://www.arubanetworks.com/assets/tg/TG_OWE.pdf
