LLDP-MED (Link Layer Discovery Protocol – Media Endpoint Discovery) is specifically designed to extend standard LLDP functionality for media endpoints such as VoIP phones. On AOS-CX switches, LLDP-MED can advertise network-policy information and power-related information directly to a connected IP telephone.

HPE Aruba Networking documents that the LLDP-MED network-policy TLV allows endpoints and network devices to exchange the voice VLAN ID, IEEE 802.1p priority, and DSCP values associated with voice applications. This enables a connected VoIP phone to automatically obtain the QoS information required for correct voice traffic classification. Aruba Networking

LLDP-MED also supports PoE information through MED TLVs. AOS-CX provides the lldp med poe capability to advertise Power over Ethernet Data Link Layer Classification information and, where configured, PoE priority information. Aruba Networking

Standard LLDP provides basic device discovery but LLDP-MED adds the media-specific extensions required here. LACP negotiates link aggregation and has no role in voice endpoint provisioning. CDP is Cisco ' s proprietary discovery protocol and is not the standards-based AOS-CX mechanism specified for this purpose.

Therefore, LLDP-MED is the protocol that satisfies both the DSCP/QoS and PoE provisioning requirements.

The correct built-in AOS-CX management role is administrators. HPE Aruba Networking defines the administrators group as the default role with full management privileges and explicitly assigns it privilege level 15. Members of this group can perform firmware upgrades, modify switch configuration, view sensitive configuration information, add or remove local user accounts, change passwords, and use all supported REST API methods. Aruba Networking

The existing auditors assignment does not satisfy the requirement. The auditors group is intentionally restricted to audit-related operations and is assigned privilege level 19, not 15. Its CLI access is limited to the auditor context, and its Web UI and REST API permissions are similarly restricted to logging and auditing resources. Aruba Networking

AOS-CX also documents the mapping used with TACACS+: privilege level 15 maps to administrators, privilege level 1 maps to operators, and privilege level 19 maps to auditors. Aruba Networking

Therefore, because this user needs both firmware-upgrade capability and privilege level 15, the appropriate default management role is administrators.

In MSTP, root-bridge priority is configured per MST instance , not directly per individual VLAN. Since Core-1 already has spanning-tree instance 1 priority 0, Core-1 is intended to become the preferred root for MST instance 1 . To make VLAN 10 use that spanning-tree topology, VLAN 10 must therefore be mapped into instance 1 with:

spanning-tree instance 1 vlan 10

HPE Aruba Networking documents this exact syntax and states that the command either creates an MST instance with the specified VLAN mapping or maps a VLAN to an existing instance. Aruba Networks

This is how MSTP provides VLAN load balancing. Different VLANs can be assigned to separate MST instances, and each instance can have a different root bridge. For example, VLAN 10 can belong to instance 1 with Core-1 as root, while VLAN 20 can belong to another instance whose root priority favors Core-2 . Aruba specifically describes this ability to forward different VLAN groups along separate paths as an MSTP load-sharing mechanism. Aruba Networks

Options B, C, and D are not the appropriate AOS-CX MSTP VLAN-to-instance mapping syntax. The required command is therefore A .
