Pass the HP Aruba Certified Professional - Campus Access HPE7-A01 Questions and answers with CertsForce

When a UXI sensor must be deployed into an environment protected by 802.1X but lacks cellular connectivity, the appropriate bootstrap mechanism is the UXI Onboarding application using Bluetooth. The sensor initially cannot authenticate to the protected network because it has not yet obtained the required 802.1X credentials, certificates, or other connectivity configuration. Bluetooth provides an out-of-band path for supplying that initial configuration.

HPE Aruba Networking ' s UXI onboarding documentation states that when Ethernet connectivity or cellular onboarding is unavailable, the UXI onboarding app can send the sensor ' s initial configuration over Bluetooth. The application supports configuring network parameters including 802.1X credentials and certificates. Cape Networks Help Center

HPE ' s UXI QuickSpecs likewise confirms that UXI sensors include a Bluetooth 5.0 radio specifically enabling setup through the UXI mobile application. Hewlett Packard Enterprise

Therefore, D is correct. Barcode scanning alone does not solve the sensor ' s protected-network connectivity requirement. Sensors are not onboarded by daisy-chaining configuration from another UXI, and UXI deployment is not based on serial-CLI provisioning.

According to the Aruba Documentation Portal1, 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 network2. The GRE protocol is used to encapsulate and decapsulate the traffic between the access points and the controller3.

Therefore, option C is correct.

 The system-mac command is used to configure a fixed MAC address for the VSX system. This MAC address is used as the source MAC address for all routed traffic from the VSX node. The system-mac command is highly recommended for preventing traffic disruptions when the primary VSX switch restores after the secondary VSX switch, such as during a primary switch hardware replacement or a power outage2. During the initial VSX configuration, the system-mac is assigned with a fixed MAC based on VSX ID. The system-mac command can be used to change this default MAC address if needed2. Therefore, answer D is correct.

PAPI is the protocol that is used to establish tunnels between the CX switch and the Aruba Gateway for Dynamic Segmentation1. By default, PAPI uses a simple checksum to verify the integrity of the messages, but it does not encrypt the payload2. This could expose the network to spoofing or replay attacks by malicious actors. To address this situation, the administrator must enable Enhanced PAPI security, which uses AES-256 encryption and HMAC-SHA1 authentication to protect the tunnel traffic2. Enhanced PAPI security can be enabled on the CX switch by using the command system papi enhanced-security enable3. This will ensure that the tunnels built between the CX switch and the Aruba Gateway are encrypted and authenticated.

In the AOS-CX behavior covered by this Campus Access question, an HPE Compute/Server DAC is treated as an unsupported transceiver product when it is not specifically included in the supported Aruba CX transceiver matrix. HPE Aruba ' s AOS-CX Fundamentals documentation explicitly identifies HPE-branded products intended for HPE Compute Servers or Storage as examples of products classified as unsupported for AOS-CX switching platforms. Aruba Networking

The AOS-CX mechanism for permitting such devices is Unsupported Transceiver Mode (UT-mode) , controlled using the global:

allow-unsupported-transceiver

command. The command permits unsupported optical transceivers, DACs, and AOCs to establish connections on supported interfaces. Aruba Networking

Therefore, for the certification scenario, the Server DAC connected to interface 1/1/26 requires allow-unsupported-transceiver to be enabled, making C the intended answer. Simply stating that the port remains disabled describes the consequence when unsupported-transceiver operation is not permitted, but C identifies the actual configuration requirement.

Be aware that Aruba has changed default UT-mode behavior in later AOS-CX releases, so this question should be interpreted according to the course/exam software context rather than assuming every current release behaves identically. Aruba Networking

Option C is the correct configuration to ensure that APs will work properly. It uses the ap command to configure a port profile for APs with VLAN 100 as the native VLAN and VLAN 200 and 300 as tagged VLANs. It also enables LLDP on the ports to discover the APs and assign them to the port profile automatically. The other options are incorrect because they either do not use the ap command, do not enable LLDP, or do not configure the VLANs correctly.

MPSK Local is a feature that can reduce the IT administration overhead associated with deploying devices that do not support 802.1X authentication while maintaining a secure environment. MPSK Local allows the switch to automatically generate and assign unique pre-shared keys for devices based on their MAC addresses, without requiring any configuration on the devices or an external authentication server. The other options are incorrect because they either require manual intervention by the installers or the MPSK gateway, or they do not provide unique pre-shared keys for devices.

AOS-CX Active Gateway is used with a VSX pair to provide an active-active first-hop gateway. Both VSX peers share the same virtual IP address and virtual MAC address (VMAC), allowing either peer to route traffic received from downstream hosts.

HPE Aruba Networking documents that each Active Gateway periodically sends a broadcast hello packet so that downstream access switches continue learning the Active Gateway VMAC and do not age it out of their MAC address tables . HPE Support

For this Active Gateway hello mechanism, the relevant implementation is a Layer 2, non-IP Ethernet packet . This is consistent with its purpose: the packet is used primarily to refresh Layer 2 MAC learning for the shared VMAC rather than to establish an IP-layer neighbor relationship.

The other answers correspond to unrelated mechanisms. UDP port 5555 is associated in Aruba environments with functions such as AP packet-capture traffic, not VSX Active Gateway hello operation. Aruba Networks TCP port 6363 and multicast address 224.0.1.3 are likewise not used for Active Gateway hello messages.

Therefore, the correct answer is D. Non-IP Ethernet packet .

The information that the Inter-Switch Link Protocol configuration uses in the configuration created is B. MAC tables.

The Inter-Switch Link Protocol (ISL) is a protocol that enables the synchronization of data and state information between two VSX peer switches. The ISL uses a version control mechanism and provides backward compatibility regarding VSX synchronization capabilities. The ISL can span long distances (transceiver dependent) and supports different speeds, such as 10G, 25G, 40G, or 100G1.

One of the data components that the ISL synchronizes is the MAC table, which is a database that stores the MAC addresses of the devices connected to the switch and the corresponding ports or VLANs. The ISL ensures that both VSX peers have the same MAC table entries and can forward traffic to the correct destination2. The ISL also synchronizes other data components, such as ARP table, LACP states for VSX LAGs, and MSTP states2.
