Free Practice Questions for HP HPE7-A07 Exam

The Change of Authorization (CoA) messages are used in network access control scenarios and are typically received by the network access server, in this case, an Aruba AOS 10 Gateway. The correct command to verify the receipt of a CoA message is related to the control path traffic because CoA is a control plane function.

Option B, packet-capture controlpath udp 3799, is the correct answer because it specifies capturing control plane traffic on UDP port 3799, which is the standard port for CoA messages.

Options A, C, and D are incorrect because:

Option A captures data plane traffic, not control plane traffic.

Option C's packet-capture interprocess udp 3799 does not refer to a standard command for capturing CoA messages.

Option D, tcpdump host-port 3799, does not specify the correct syntax for capturing traffic on Aruba devices.

When configuring an 802.1X supplicant in Microsoft Windows for EAP-PEAP (Protected EAP) using EAP-MSCHAPv2, both user and machine credentials can be used for authentication. The network administrator has already enabled user and machine authentication under Additional Settings, but to meet the stated requirements (AES encryption and server certificate validation), two critical steps remain:

Enable server certificate validationThis ensures the client validates the identity of the RADIUS server (such as Aruba ClearPass or another authentication server) to prevent man-in-the-middle attacks. It satisfies the requirement for “validation of server certificate in Windows 10”.

Exact Extract:

“For EAP-PEAP with EAP-MSCHAPv2, select ‘Validate server certificate’ to ensure the client trusts the authentication server’s identity. The server certificate must be signed by a CA trusted by the client.”

Enable user authenticationWhile both user and machine authentication are possible, user authentication must be explicitly enabled so that credentials (domain or local user) are sent after machine authentication completes. This enables the full EAP-MSCHAPv2-based user and machine authentication process.

Exact Extract:

“In EAP-PEAP properties, ensure ‘Enable user authentication’ is selected to authenticate both the workstation and logged-on user credentials when using EAP-MSCHAPv2.”

Additionally, Windows 10 uses AES encryption automatically when WPA2/WPA3-Enterprise is configured, fulfilling requirement (1). RC4 encryption is not applicable because AES is the default cipher for WPA2 Enterprise networks.

Why the Other Options Are Incorrect:

C. EAP-TLS-based user and machine authentication:The question specifies EAP-MSCHAPv2, not EAP-TLS. EAP-TLS uses digital certificates for mutual authentication, while PEAP with EAP-MSCHAPv2 uses username and password-based credentials.

“EAP-TLS is certificate-based; PEAP-MSCHAPv2 uses password-based authentication.”

D. Change default RC4 encryption for AES:RC4 is used in older WPA or TKIP security types. When using WPA2-Enterprise, AES is automatically selected and cannot be manually overridden.

“WPA2-Enterprise (802.1X) uses AES-CCMP encryption; RC4/TKIP is not applicable to modern configurations.”

To maximize wired bandwidth utilization, especially when multiple APs are terminating on mobility gateways, it's best practice to aggregate physical ports into a port channel. This provides redundancy and increased bandwidth by combining the throughput of multiple ports.

The fallback role is used as a default role in the absence of a specified role or when an authentication server is not available. Given the scenario, where the test device with MAC address 81:cd:93:13:ab:31 needs to be assigned to "iot-prod" and other devices to "iot-default", and considering there is no external authentication server configured for the test, the appropriate action would be to set a global fallback role that applies to all devices connecting to the network. This ensures that any device that does not match the specific device profile will inherit the "iot-default" role. Since the configuration for a specific MAC address (81:cd:93:xx:xx:xx) to associate with the "iot-prod" role is already in place, setting the fallback role globally accommodates the requirement for other devices.

In HPE Aruba Networking (AOS-CX and AOS-Switch) OSPF implementation, the routing behavior for external routes (Type 5 LSAs) distinguishes between two types of external advertisements:

E1 (Type-1 external) — The total path cost is calculated as the sum of the internal cost to reach the ASBR (Autonomous System Boundary Router) plus the external cost as advertised in the LSA.

E2 (Type-2 external) — The external cost is considered independent of the internal OSPF path cost to reach the ASBR. Thus, the metric used is only the external cost from the LSA.

When both an E1 and an E2 route exist to the same external destination, OSPF gives preference to the E1 route, regardless of metric values, because the E1 route represents a more accurate total cost to the destination (including internal OSPF cost).

Extract (as per HPE Aruba OSPF Technical Overview and AOS-CX Routing Guide):

“When both Type-1 (E1) and Type-2 (E2) external LSAs for the same destination are present, the router always prefers the Type-1 route. Type-1 routes include both internal and external costs in the total metric, while Type-2 routes use only the external cost. The E1 path is therefore considered more precise and is selected as the preferred route.”

This is consistent across Aruba’s OSPF implementation and follows standard OSPF behavior as defined by the protocol (RFC 2328).

Therefore, when both E1 and E2 routes are available and have the same overall cost, the router will always prefer the E1 path.

In WLANs, multicast frames are transmitted at the lowest basic rate, so a single multicast stream can consume significant airtime and slow the entire BSS, impacting clients that did not even join the group.

Dynamic Multicast Optimization (DMO) converts multicast streams to per-client unicast, allowing the AP to use the highest supported unicast data rate and reliable retransmission—this prevents the low-rate multicast airtime penalty.

Multicast Transmission Optimization (MTO) raises the transmit rate for any remaining multicast/broadcast that must still be sent as multicast, further reducing airtime.

The captures show multicast sent as 802.11 data at a low rate; enabling DMO + MTO addresses exactly this symptom in Aruba deployments.

When onboarding devices into a centralized management system, each device can have its individual admin password set during the onboarding process. If this password doesn't match what is expected at the group level in the central management platform, login issues such as the one described can occur.

The CLI output provided shows routing information from a CX 6300 switch. The output under "VRF: default" shows various IP routes, including a route for 10.203.1.100/32 with a next hop of 172.21.11.2. This indicates that the route to the client with IP address 10.203.1.100 is known in the network and is reachable via another device in the fabric, which has the loopback IP address 172.21.11.2. Since the route is present in the routing table, it means that the client is known and active within the fabric network.
