HP Updated HPE7-A01 Exam Questions and Answers by arwen

HPE Aruba Networking Central performs rogue AP detection, classification, and containment through RAPIDS (Rogue Access Point Intrusion Detection System). In the Classic Central interface, detected wireless devices are managed under Security > RAPIDS > Rogues. RAPIDS categorizes detected APs as Rogue, Suspected Rogue, Interfering, Neighbor, Manually Contained, or other applicable states. Aruba Networking

For manual reclassification, the administrator selects the detected AP, chooses Reclassify, and then selects the desired classification. Aruba documentation explicitly lists Rogue, Neighbor, and Manually contained among the available manual classifications. A Manually contained classification enables rogue containment against the selected AP, subject to the required containment configuration being enabled. Aruba Networking

Therefore, Security > RAPIDS is the appropriate location for this task. Applications > IDS/IPS is not the workflow used to reclassify detected APs. Devices > Access Points primarily manages authorized infrastructure APs rather than RAPIDS classifications. Audit Trail records administrative and system activities; it is not the rogue-device classification interface.

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 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
