A large retail company with hundreds of stores is planning to deploy a standardized network architecture managed from a single point of control. A key requirement is zero-touch provisioning (ZTP) for new store deployments to minimize the need for onsite IT staff. After analyzing this requirement, the architect determines the solution must be cloud-based. Which HPE Aruba Networking product is the foundation for this architecture?
Show answer details
Correct answer: A
HPE Aruba Networking Central is Aruba's cloud-based network management and operations platform. It is specifically designed for distributed enterprises and provides key features like ZTP, centralized configuration management via templates and groups, monitoring, and reporting, which perfectly match the retailer's requirements.

True or False: In a VSX environment, the Inter-Switch Link (ISL) is used exclusively for control plane synchronization and keepalives; it does not carry any end-user data traffic.
Show answer details
Correct answer: B
This statement is false. While the ISL's primary roles are synchronization and keepalives, it also serves as a data path for traffic that needs to traverse between the VSX peers. This can happen for 'orphan' devices connected to only one peer or for Layer 3 traffic that is routed on one peer but needs to egress via a link on the other peer. This is often called the 'data plane' function of the ISL.

A manufacturing plant is upgrading its network to support a large deployment of IoT sensors and automated machinery. A key technical objective is to minimize network convergence time to less than 200ms in the event of a link or switch failure in the distribution layer. The proposed design uses OSPF as the routing protocol. Which OSPF feature must be included in the architecture to meet this stringent convergence requirement?
Show answer details
Correct answer: B
OSPF's default dead timers are several seconds long, which is too slow for the requirement. Bidirectional Forwarding Detection (BFD) is a protocol designed to provide very fast failure detection for routing protocols. By enabling BFD for OSPF adjacencies, link failures can be detected in milliseconds, allowing OSPF to converge almost instantly and meet the sub-200ms requirement. Stub areas, route summarization, and virtual links are OSPF features for topology management and scaling, not fast convergence.

A network architect is designing a solution for a company that has a strict policy against using proprietary vendor lock-in technologies. The design requires a high-availability solution at the core layer that supports active-active forwarding and is based on open standards. Which technology should the architect prioritize in the design?
Show answer details
Correct answer: C
BGP EVPN (Ethernet VPN) is an open, standards-based technology (RFC 7432) used as a control plane for network virtualization overlays like VXLAN. It provides advanced features like active-active multihoming for redundant server connections, which meets the high-availability requirement without vendor lock-in. VSF and VSX are powerful but are HPE Aruba-specific technologies. VRRP is a standard but provides active-standby gateway redundancy, not active-active forwarding for multi-homed links.

After presenting a network design to a customer, the technical lead raises a concern about a documented assumption: 'It is assumed that the existing building-to-building fiber runs have sufficient capacity for 10GbE uplinks.' The architect has not physically verified these fiber runs. What is the most significant risk associated with this unverified assumption?
Show answer details
Correct answer: B
The most significant risk is that the physical infrastructure cannot support the proposed design. If the existing fiber is older multimode (e.g., OM1) it may not support 10GbE over the required distance. Discovering this during implementation would force a costly and time-consuming remediation (pulling new fiber), leading to major project delays and budget overruns. The other options are secondary consequences of this primary physical layer failure.

A consultant is performing a network assessment and needs to identify all active devices on the current network, map their physical interconnections, and retrieve basic configuration details like VLANs and STP status. Which tool or protocol is most effective for automatically discovering this Layer 2 topology information in a multi-vendor environment?
Show answer details
Correct answer: C
LLDP (and its Cisco proprietary equivalent, CDP) is specifically designed for neighbor discovery on Layer 2. Network devices use LLDP to advertise their identity and capabilities to adjacent devices. By querying the LLDP information from all switches, an architect can accurately map the physical topology (which switch port connects to which other switch port). SNMP can retrieve configuration data but is less direct for topology mapping. NetFlow is for traffic analysis.

An architect is designing a wireless network for a convention center that will host multiple, simultaneous events for different organizations. The design must ensure that each organization's wireless traffic is completely isolated and that they cannot see or interact with each other's devices (e.g., printers, casting devices). Which Aruba technology is designed for this specific multi-tenant scenario?
Show answer details
Correct answer: B
AirGroup is the Aruba technology that manages device discovery protocols like mDNS (Bonjour) and SSDP. In a multi-tenant environment, AirGroup can be configured to create separate domains, ensuring that users associated with one event (and one user role/VLAN) can only discover and interact with devices within their own group. This prevents broadcast and multicast traffic from leaking between tenants, providing the required isolation.

A financial services firm is architecting a new campus network and requires strict traffic separation between its Corporate, Guest, and high-frequency Trading user groups. The primary design goal is to enforce security policies at the network edge and ensure that traffic from one group cannot be snooped by another, even within the same physical switch. The solution must scale to hundreds of policies. Which HPE Aruba Networking technology is specifically designed to meet this requirement by creating encrypted tunnels from the access switch to the gateway cluster?
Show answer details
Correct answer: B
Dynamic Segmentation is the correct technology. It uses a centralized, policy-based approach to create secure GRE tunnels from the access device (switch or AP) to a Gateway Cluster. This encapsulates user traffic and enforces policies centrally, providing the required traffic isolation and security at the edge. VSX is for high availability, EVPN-VXLAN is a fabric technology, and VSF is for switch stacking; none provide this specific user-to-gateway tunneling mechanism for policy enforcement.

During the analysis phase for a university campus network upgrade, the architect identifies two critical requirements: 1) The ability to provide Layer 2 adjacency for a legacy application across different campus buildings, and 2) A scalable, standards-based underlay and overlay that simplifies network management. Which combination of technologies should the architect select for the final design? (Select TWO)
Show answer details
Correct answer: B, C
BGP is the standard control plane protocol for EVPN, used to distribute MAC and IP reachability information across the VXLAN fabric, making it a key component of the solution.
EVPN-VXLAN is a modern fabric technology that provides Layer 2 extension over a Layer 3 underlay. This directly addresses the requirement for L2 adjacency across buildings while offering a scalable, standards-based overlay.

A consultant is creating a proposal document for a new campus design. To illustrate the planned, phased migration from the existing legacy network to the new HPE Aruba Networking architecture, which type of diagram would be most effective for conveying the project timeline and dependencies to stakeholders?
Show answer details
Correct answer: C
A Gantt chart is a project management tool specifically designed to illustrate a project schedule over time. It is ideal for showing the start and end dates of different phases (e.g., core upgrade, distribution rollout, access layer refresh), their dependencies, and the overall project timeline, making it perfect for a migration plan. The other diagram types are used for showing data relationships, interactions, or system states, not project timelines.
