According to the Aruba Documentation Portal 1 , the Aruba 6300 CX switches support various features to control the PoE devices on specific ports, such as device profiles and classifier policies. These features can help reduce the power consumption and improve the performance of the PoE devices.

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, LLD P-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.

VSX clustering is a feature that allows two Aruba CX switches to operate as a single logical device, providing high availability, scalability, and simplified management. VSX clustering has several benefits over spanning tree configuration, such as:

Dual control plane provides better resiliency. Unlike stacking, where switches share a single control plane, VSX switches have independent control planes that synchronize their states over an inter-switch link (ISL). This means that if one switch fails or reboots, the other switch can continue to operate without affecting traffic flows or network services.

Active-active forwarding provides better performance. Unlike spanning tree, where some links are blocked to prevent loops, VSX switches use all available links for forwarding traffic, providing load balancing and increased bandwidth utilization.

Multichassis LAG provides better redundancy. Unlike single-chassis LAG, where all member ports belong to one switch, VSX switches can form multichassis LAGs with downstream or upstream devices, where member ports are distributed across both switches. This provides link redundancy and seamless failover in case of switch or port failure.

According to the Aruba Documentation Portal 1 , the ArubaOS-CX switch supports various features to control the ingress traffic on specific ports, such as rate limiting, QoS shaping, and access control. These features can help reduce the impact of excessive broadcast traffic on the network performance and availability.

This is because rate limiting is a feature that allows you to limit the inbound or outbound traffic on a port based on a percentage of the port capacity or a fixed amount of bytes per second.  Rate limiting can help prevent broadcast storms by reducing the amount of broadcast packets that enter or leave a port

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.

To create a new OSPF configuration for a separate routing table, you need to create a new OSPF process ID with vrf name. This will create a new OSPF instance that is associated with the specified VRF and its routing table. The other options are incorrect because they either do not create a new OSPF instance or do not associate it with a VRF.

According to the Aruba Documentation Portal 1 , 802.1X is a standard for port-based network access control that uses a RADIUS server to authenticate and authorize wireless clients. 802.1X can be configured in different modes, such as bridge mode, tunnel mode, or split tunnel mode.

Option C: GRE tunnel

This is because option C shows how to configure an SSID in tunnel mode with the default AP-group settings on an Aruba switch.  In tunnel mode, all client traffic from the access points is tunneled back to the controller and the controller would in turn put the client traffic onto the network 2 .  The GRE protocol is used to encapsulate and decapsulate the traffic between the access points and the controller 3 .

Therefore, option C is correct.

The required optimization is to use IEEE 802.3az Energy Efficient Ethernet (EEE) across the AP deployment. Aruba documentation states that 802.3az allows supported APs to consume less power during periods of low data activity , which directly matches the scenario of reducing nighttime energy consumption. Aruba Networking

However, Aruba explicitly documents that 802.3az is not supported on the AP-315 or the 330 Series , which includes the AP-335. Aruba Networking Consequently, those older AP-315 and AP-335 units must be replaced with models supporting EEE. The AP-515 belongs to a newer generation and does not fall within Aruba ' s documented EEE exclusions, so replacing the AP-515 is unnecessary.

After installing EEE-capable replacements, 802.3az should be enabled across the AP environment , allowing Ethernet links to reduce power usage during low-traffic periods.

IPM is not the primary mechanism for this requirement. Aruba describes Intelligent Power Monitoring as dynamically restricting AP functions when AP consumption approaches or exceeds its available power budget . It is primarily concerned with operating an AP within available PoE resources, rather than automatically exploiting nighttime Ethernet inactivity. Aruba Networking

The command loop-protect enables loop protection on each layer 2 interface (port, LAG, or VLAN) for which loop protection is needed. Loop protection can find loops in untagged layer 2 links, as well as on tagged VLANs.
