HPE7-A07 Dumps with Practice Exam Questions Answers

The configuration shown in the third exhibit details a client role mapping that associates different client profile tags with specific client roles. When a new device, such as an Android phone, connects to the network, it will be profiled and assigned a role based on the mappings defined. If the device does not match any predefined profiles, it would be assigned the "unmatched-device" role. This is under the assumption that default settings are in place and the client does not match the criteria for any of the specific roles like "byod", "iot-internet", or "iot-local". Therefore, an Android phone connecting for the first time and not matching any specific profile tag would be assigned to the "unmatched-device" role.

Comprehensive and Detailed Explanation From Exact Extract of HPE Aruba Networking Switching:

On Aruba switches (AOS-CX/AOS-S), multiple IPv4 networks can be configured on the same VLAN interface (SVI) by assigning a primary address and one or more secondary addresses. The VLAN remains one Layer-2 broadcast domain; adding more IP subnets does not create subinterfaces and does not split the broadcast domain.

Exact extract:

“A VLAN interface may be configured with a primary IP address and additional secondary IP addresses to host multiple subnets on the same Layer-2 broadcast domain.”

“A VLAN is a single broadcast domain. Broadcast and unknown unicast frames are flooded to all ports belonging to the VLAN.”

“Hosts in different IP subnets on the same VLAN still require Layer-3 routing to communicate; sharing the VLAN only means they share the same L2 broadcast domain.”

Therefore, when a second subnet is added to the same VLAN, broadcasts (ARP, DHCP, etc.) from devices in either subnet will be flooded to all member ports of that VLAN, making option C correct.

Options A (subinterfaces) are not used here; B is incorrect because inter-subnet traffic still needs routing; D is not categorically true—IGMP operates per VLAN with multicast routing configuration and is not inherently disabled by multiple subnets.

Comprehensive and Detailed Explanation From Exact Extract of HPE Aruba Networking Switching:

In AOS-10 wireless deployments, HPE Aruba Networking supports the configuration of Primary and Secondary Gateway Clusters in the SSID profile to ensure high availability, redundancy, and load distribution. This configuration follows Aruba’s gateway clustering best practices, where access points (APs) attempt to establish tunnels with their Primary Gateway Cluster first. If the AP cannot reach the primary cluster (due to reachability, latency, or network topology), it automatically connects to the Secondary Gateway Cluster.

When both gateway clusters are active and reachable but some APs cannot reach the primary cluster—for example, due to Layer 3 routing, firewall restrictions, or network segmentation—those APs will associate with the secondary cluster instead. This results in an approximately equal split of APs across both clusters, even though the primary cluster is operational.

Exact Extract from HPE Aruba Networking Switching and AOS-10 Gateway Documentation:

“Access Points attempt to form tunnels with the Primary Gateway Cluster first. If the primary cluster is unreachable or fails to respond within the defined timeout, the AP establishes a tunnel with the Secondary Gateway Cluster.”

“When the primary and secondary gateway clusters are both up but APs are distributed across separate routed networks or VLANs, APs may select the gateway cluster that is most reachable at that time, resulting in an even or partial split of AP distribution.”

“This is expected behavior when APs in different subnets cannot reach the same primary cluster due to network topology. The secondary cluster provides redundancy and connectivity continuity.”

Therefore, the equal split of 260 APs is explained by the fact that while the primary cluster is active, a subset of APs cannot reach it due to routing or segmentation and thus join the secondary cluster—this behavior aligns with Aruba’s gateway redundancy mechanism.

Why the Other Options Are Incorrect:

A. The statement reverses the cause: APs that cannot reach the primary connect to the secondary—not the other way around. The secondary cluster’s reachability does not affect AP selection when the primary is available and reachable.

“APs first attempt the primary cluster; only failure to reach it triggers fallback to secondary.”

B. Secondary cluster is homogeneous:Cluster homogeneity refers to identical hardware/software versions between gateways; it does not influence AP distribution or equal load split.

“Homogeneity is a software version consideration, not an AP load-balancing factor.”

C. Secondary cluster is heterogeneous:Heterogeneity (mixed hardware types) is unsupported or discouraged; it does not cause AP distribution behavior.

“Heterogeneous gateway clusters are not a cause of AP distribution variation; cluster type does not dictate AP split.”

In a multi-site deployment with a mix of bridged and tunneled SSIDs, if there are session sync errors between different areas, it could be due to connectivity issues with the central management platform, which in the case of Aruba, is likely HPE Aruba Networking Central. This interruption could cause inconsistencies in session states across the network.

In Aruba's infrastructure, the Access Points (APs) are configured with primary and secondary gateway clusters to ensure connectivity and resiliency. The APs will failover to the secondary gateway cluster if they are unable to reach the primary gateway cluster, even if the primary cluster is operational. This mechanism ensures that the APs maintain connectivity to the network infrastructure for continuous service delivery.
