The Aruba Certified Campus Access Professional Exam (HPE7-A01)

These are two benefits enabled by LLDP-MED (Link Layer Discovery Protocol - Media Endpoint Discovery). LLDP-MED is an extension of LLDP that provides additional capabilities for network devices such as VoIP phones and APs. One of the capabilities is to automatically configure voice VLANs for VoIP phones, which allows them to be placed in a separate VLAN from data devices and receive QoS and security policies. Another capability is to request power as needed from PoE-enabled switch ports, which allows APs to adjust their power consumption and performance based on the available power budget. The other options are incorrect because they are either not enabled by LLDP-MED or not related to LLDP-MED.

To allow a new VLAN 100 between VSX pair inter-switch-link 256 for port 1/45 and 2/45, you need to use the command vlan trunk allowed 100 in LAG256. This will add VLAN 100 to the list of allowed VLANs on the trunk port LAG256, which is part of the inter-switch-link between VSX peers. The other options are incorrect because they either do not use the correct command or do not specify the correct port or VLAN.

Change of Authorization (CoA) is a feature that allows ClearPass Policy Manager (CPPM) to send messages to network devices such as switches to change the authorization state of a user session. CoA requires that both CPPM and the network device support this feature and have it enabled. For AOS-CX switches, CoA must be globally enabled using the command radius-server coa enable. If CoA is not enabled on the switch, the disconnect CoA message from CPPM will be ignored and the user session will not be terminated.

The correct answer is A. SNMPv3.

SNMPv3 is a protocol that is used to retrieve data stored in a Management Information Base (MIB), which is a database of managed objects in a network. SNMPv3 provides security and access control features that are not available in earlier versions of SNMP. SNMPv3 can also use encryption to protect the data from unauthorized access or modification.

According to the Aruba Certified Professional – Campus Access document1, one of the skills that this certification validates is:

Implement and Analyze the output from common network monitoring tools

Configure Port Mirroring to collect PCAPs

Configure NAE agents 9.4

Configure UXI sensors for internal and external tests

Describe how API scan be used to configure, manage, monitor, and troubleshoot your network

The document also mentions that the candidate should have a distinguished understanding of different protocols across vendors, which implies that they should be familiar with SNMPv3 and how it can be used to access MIB data.

 Aruba Installer App is a mobile app that simplifies site installations and enables network connectivity for Aruba devices. The app allows the user to scan the barcode of the device and add it to the network using Aruba Central. The app also automates importing Aruba devices into Aruba NetEdit for intelligent configuration management and continuous conformance validation

Two parts of the solution for these requirements are Option C and Option E.

Option C is a part of the solution because it defines a policy-based routing action list named route_test, which specifies the next hop IP address as 10.1.1.253 for the matching traffic. This is the new default route that the user wants to use for the subnet 10.2.250.0/24. The interface null parameter indicates that the traffic will be routed to the next hop without using a specific interface1.

Option E is a part of the solution because it applies the policy-based routing action list route_test to the VLAN interface 250, which has an IP address of 10.2.250.1/24. This is the subnet that the user wants to test the new default route for. The apply policy command enables policy-based routing on the interface and associates it with the action list2.

Option A is not a part of the solution because it defines a policy-based routing action list named route_test, but does not specify the next hop IP address as 10.1.1.253, which is the new default route that the user wants to use. Instead, it specifies a next hop IP address of 10.1.1.254, which is different from the requirement.

Option B is not a part of the solution because it defines a policy-based routing action list named route_test, but does not specify any next hop IP address at all, which is necessary for policy-based routing to work. Instead, it specifies an interface null parameter without any IP address, which is invalid.

Option D is not a part of the solution because it applies the policy-based routing action list route_test to the VLAN interface 200, which has an IP address of 10.2.200.1/24. This is not the subnet that the user wants to test the new default route for, but a different subnet that should not be affected by this change.

Aruba CX 6300 switches support various features to control the port access for different types of devices, such as client mode, device mode, and multidomain mode. These features can help limit the number of clients that can connect to a port and prevent unauthorized devices from accessing the network.

This is because option C shows how to configure the client limit and the auth-mode for a specific port using the interface command and the aaa authentication port-access command. The client limit specifies the maximum number of clients that can connect to a port. The auth-mode specifies the authentication mode for the port. In this case, option C sets both parameters to multi-domain mode, which allows only one voice device and one data device to be authenticated on a port

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

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.
