They must dynamically assign 5,000 newly onboarded AOS-CX switches into specific Configuration Groups based on their role, and apply appropriate Device Tags for monitoring. The enterprise utilizes a multi-tenant architecture with two distinct GreenLake Workspaces: Workspace_Corp and Workspace_Retail. The administrator executes a bulk API script to apply the tag [Status: Pre-Prod] and assign the switches to the Grp_Access_Baseline Configuration Group. API Response Snippet: { "success": 2450, "failed": 2550, "errors": [ { "device_mac": "00:1A:2B:3C:4D:5E", "error": "Group Grp_Access_Baseline not found in current context." }, { "device_mac": "00:1A:2B:3C:4D:5F", "error": "Tag assignment failed: Device belongs to a different tenant workspace." } ] } Based on the interaction between Workspace boundaries, Configuration Groups, and Tagging mechanics, which THREE statements explain these API failures? (Select all that apply.) A. Devices must be fully licensed and assigned to a Configuration Group BEFORE any Device Tags can be applied to them via the Central API. B. Configuration Groups are strictly bounded within a single Workspace. A group named Grp_Access_Baseline created in Workspace_Corp does not exist and cannot be referenced by devices in Workspace_Retail. C. Device Tags are global entities within GreenLake; however, the API token used was scoped strictly to Workspace_Corp, preventing tag application on devices residing in Workspace_Retail. D. True multi-tenant automation requires executing the group assignment and tagging API calls independently against the specific API Gateway endpoint corresponding to each distinct Workspace. E. The API script failed because it attempted to assign a tag ([Status: Pre-Prod]) that contains special characters (brackets and hyphens), which violates Central's tag naming conventions. Answer: B, C, D 2.An enterprise deploys AOS-10 Campus APs that tunnel traffic to a centralized Gateway cluster. The campus network enforces strict Zero Trust using 802.1X port-based security on all wired AOS-CX access switches. The APs must cryptographically authenticate to the switch port before gaining uplink access to the network. [AOS-CX Switch - Port Access Configuration] interface 1/1/5 port-access dot1x enable Download Valid HPE6-A90 PDF Dumps for Best Preparation 3 / 7 port-access role AP_UPLINK vlan access 10 Which THREE statements accurately describe the interaction between the AP's wired uplink authentication and the subsequent AOS-10 tunnel orchestration process? (Select all that apply.) A. If the AP fails 802.1X authentication at the switch port, it immediately reverts to Bridge mode forwarding to ensure localized IoT clients can still access the internet via the restricted fallback VLAN. B. After the AP checks in, the Central Tunnel Orchestrator service utilizes the AP's active cloud connection to securely push the routing tables and cryptographic material needed to build the data plane tunnels to the Gateway cluster. C. Once the switch port authorizes the AP and places it on the management VLAN (VLAN 10), the AP requests a DHCP address and establishes a secure WebSocket connection to HPE Aruba Networking Central. D. The upstream AOS-CX switch must dynamically push the IPsec tunnel destination IP addresses directly to the AP via a proprietary RADIUS Vendor-Specific Attribute (VSA) upon successful 802.1X authentication. E. The AOS-10 AP acts as an 802.1X supplicant, utilizing its factory-installed Trusted Platform Module (TPM) certificate or a Central-provisioned certificate to authenticate against the wired switch port. Answer: B, C, E 3.What is the primary method to securely execute CLI commands on an AOS-10 Gateway managed by Central without requiring direct network reachability to the gateway's local management IP address? A. By deploying a local Mobility Master on-premises to proxy the terminal connection back to the cloud. B. By utilizing the Remote Console feature integrated natively within the HPE Aruba Networking Central WebUI. C. By connecting a physical console cable to the gateway and using dedicated terminal emulation software. D. By establishing a direct SSH session using port 22 to the gateway's public WAN interface over the internet. Answer: B 4.Following a recent campus renovation, a NOC Operations Engineer investigates reports of severe wireless instability in a modernized open-office space. The new AOS-10 Campus APs were mounted directly on the exposed 15-foot ceilings, flush against large, metallic HVAC ductwork for aesthetic reasons. The engineer extracts the following system logs from an affected AP: Sep 14 09:12:05 ap-system[312]: <WARN> High PHY retry rate (45%) detected on radio 0 Sep 14 09:15:10 ap-rfm[441]: <ERROR> Channel utilization exceeded 80% threshold Sep 14 09:18:22 ap-system[312]: <INFO> Client a1:b2:c3:d4:e5:f6 disconnected due to excessive unacknowledged frames Based on the physical deployment constraints and the diagnostic logs, which TWO issues are the primary drivers of this network degradation? (Choose 2.) A. The metallic HVAC ductwork, owing to its high conductivity, induces severe multipath reflection and RF shadowing across operational frequency bands, directly destroying signal integrity and causing the documented 45% frame retry rate. Download Valid HPE6-A90 PDF Dumps for Best Preparation 4 / 7 B. AOS-10 firmware inherently disables MIMO processing for access points mounted above 12 feet specifically to conserve PoE power drawn from the access switch. C. The elevated PHY retry rate stems from upstream gateway cluster dropping IPsec tunnel packets, compelling the AP to retransmit payload repeatedly over the wireless medium. D. The APs were mistakenly configured with WPA2-Personal security protocol instead of WPA3, resulting in wireless driver rejection of legacy client connections due to authentication protocol incompatibilities. E. High ceiling mounting of APs in reflective environments scatters the omnidirectional RF signal, expanding coverage to include co-channel interference from neighboring floors and driving channel utilization beyond the 80% threshold. Answer: A, E 5.An HPE Aruba Solutions Consultant is assisting a customer who needs to provide the executive team with a weekly summary of AP uptime, unique client counts, and total bandwidth consumption. The executives do not have user accounts in HPE Aruba Networking Central and do not want to log into a technical dashboard. Executive Delivery Requirements Frequency: Every Monday at 08:00 AM Format: Non-editable document (PDF) Authentication: No Central login required by recipient Which Central reporting feature directly satisfies these specific delivery requirements? A. Configure an outbound Webhook via REST API to push raw JSON telemetry data directly to the executives' email inboxes. B. Create a Read-Only RBAC role mapped to an external SSO provider (SAML 2.0) so executives bypass the login screen to access the Central dashboard. C. Schedule the "Network Summary" report to automatically email a PDF to the executives' distribution list. D. Export the Central Audit Trail via the Bulk Data API and use a Python script to format the CLI output into a weekly SMS message. Answer: C 6.A Network Solutions Consultant is designing an extensive monitoring dashboard that continuously aggregates client telemetry from HPE Aruba Networking Central via REST APIs. During load testing, the API responses suddenly begin returning 429 Too Many Requests HTTP errors. Which TWO statements accurately describe the API rate limiting architecture in HPE Aruba Networking Central and how the consultant should mitigate this issue? (Choose 2.) A. Rate limits are enforced strictly on a per-application (token) basis, with specific thresholds assigned for both requests-per-second and requests-per-day. B. The consultant must distribute the API polling script across multiple source IP addresses to bypass Central's ingress IP-based rate limiting firewall. C. The consultant should refactor the code to utilize the Central Streaming API (WebSockets) to continuously ingest telemetry without consuming the REST API polling quotas. D. Central dynamically increases the API rate limit automatically if the organization purchases and assigns additional AOS-CX Advanced switch licenses to the inventory. E. Rate limits are enforced on a global per-customer tenant basis, meaning all independent API scripts Download Valid HPE6-A90 PDF Dumps for Best Preparation 5 / 7 across the entire organization share the exact same daily quota pool. Answer: A, C 7.A NOC Operations Engineer is troubleshooting a datacenter redundancy issue. Remote Microbranch APs are configured to build primary IPsec tunnels to VPNC-Primary and secondary tunnels to VPNC-Standby. When VPNC-Primary was rebooted for scheduled maintenance, the Microbranch APs failed to establish tunnels to VPNC-Standby, causing a complete site outage. [Microbranch AP Datapath Log] 10:02:15 IKE Phase 1: Initiating main mode to VPNC-Primary (198.51.100.10) 10:02:20 IKE Phase 1: Timeout connecting to VPNC-Primary 10:02:20 IKE Phase 1: Initiating main mode to VPNC-Standby (203.0.113.50) 10:02:21 IKE Phase 1: VPNC-Standby rejected proposal. MM_NO_STATE 10:02:21 ERROR: IPsec Tunnel to VPNC-Standby failed to establish. Based on the provided log data, which TWO configurations are the most likely causes of this failover failure? (Choose 2.) A. Microbranch APs inherently only support a single, non-redundant IPsec tunnel to a single VPNC to conserve memory. B. VPNC-Standby has a mismatched IPsec Pre-Shared Key (PSK) or certificate trust chain compared to the Microbranch APs' provisioning profiles. C. VPNC-Standby is missing the correct routing configuration to advertise the datacenter subnets to the remote Microbranch APs. D. The IKE/IPsec crypto maps on the VPNC-Standby do not match the encryption algorithms proposed by the remote Microbranch AP. E. The Microbranch APs lack the Advanced subscription license required to support multiple concurrent IPsec tunnel destinations. Answer: B, D 8.A Campus IT Manager is evaluating the routing architecture for a new EVPN-VXLAN overlay. They must choose between implementing a Centralized L3 Gateway design (routing at the Border/Spine) and a Distributed L3 Gateway design (Anycast gateway at the Leaf/Edge). Which THREE statements accurately evaluate the trade-offs and operational mechanics of these two architectural models? (Select all that apply.) A. Implementing a Distributed L3 Gateway requires the access layer switches (e.g., AOS-CX 6300) to support advanced routing capabilities and possess sufficient hardware resources to maintain the synchronized Anycast MAC/IP tables. B. A Distributed L3 Gateway design (Anycast Gateway) optimizes East-West traffic by routing packets at the ingress edge switch, reducing latency and avoiding traffic hairpinning through the core. C. The Distributed L3 Gateway model dictates that all external Internet-bound traffic must bypass the EVPN-VXLAN overlay entirely and route natively over the OSPF underlay. D. A Centralized L3 Gateway design inherently requires embedded Data Processing Units (DPUs) on all edge access switches to offload the massive MAC address learning tables. E. A Centralized L3 Gateway design simplifies the configuration of the access switches, as they only perform Layer 2 VXLAN encapsulation and rely entirely on the Border/Spine nodes for inter-VLAN Download Valid HPE6-A90 PDF Dumps for Best Preparation 6 / 7 routing. Answer: A, B, E 9.A Network Architect is reviewing the deployment of AOS-10 Tri-band APs. The APs require 802.3bt (Class 6 - 60W) PoE to fully power all three radios, the USB port, and the secondary Ethernet port. However, the legacy AOS-CX 6200 access switches in the building only provide 802.3at (Class 4 - 30W) PoE+. The architect reviews the switch port and Central status for one of these APs: [AOS-CX Switch] Interface 1/1/10 Power Allocated: 25.5W (Class 4) LLDP-MED Power Negotiation: Successful [Central AP Health Status] Status: Power Restricted Operational State: 2.4GHz (2x2), 5GHz (2x2), 6GHz (Disabled) Based on the provided data, which TWO statements accurately describe how the AOS-10 AP and AirMatch interact with this hardware power constraint? (Choose 2.) A. The AOS-CX switch enforces a localized Control Plane Policing (CoPP) policy to drop the AP's management traffic until a valid Class 6 midspan injector is physically installed. B. The AP leverages Intelligent Power Monitoring (IPM) to dynamically disable specific hardware features (like the 6 GHz radio) according to a prioritized list, ensuring the core functionality survives within the 30W budget. C. AirMatch automatically detects the AP's reduced power state and adjusts the overall campus RF plan, knowing that the specific AP cannot provide 6 GHz coverage or maximum EIRP on the remaining bands. D. The AP automatically transitions its remaining 2.4 GHz and 5 GHz radios into a localized Bridge mode to offset the CPU power required for IPsec encapsulation. E. AirMatch overrides the switch's LLDP-MED negotiation, forcing the port to draw 60W, which risks triggering a hardware overcurrent shutdown on the legacy AOS-CX switch. Answer: B, C 10.What is the primary purpose of enabling IGMP Snooping on an AOS-CX switch VLAN within a campus network? A. To actively prune IPv4 multicast traffic so it is only forwarded to physical ports with explicitly interested receivers. B. To prevent IPv6 multicast traffic from flooding the Layer 2 broadcast domain by utilizing MLD snooping features. C. To dynamically establish point-to-multipoint IPsec tunnels across the campus core for secure video delivery. D. To translate Layer 2 broadcast frames into unicast frames to reduce overall airtime utilization on the wireless network. Answer: A 11.A Network Architect is designing the EVPN-VXLAN overlay for a multi-building campus. The design utilizes AOS-CX 8360 switches at the core and AOS-CX 6300 switches at the edge. Download Valid HPE6-A90 PDF Dumps for Best Preparation 7 / 7 To support centralized management and micro-segmentation via Central NetConductor, how must the overlay routing be orchestrated? A. The architect must manually configure static VXLAN tunnels between each AOS-CX 6300 series access switch and the AOS-CX 8360 core switches using the device's local command-line interface (CLI). B. OSPF must be configured natively on the overlay virtual network interfaces (VNIs) to aggressively advertise the MAC addresses of connected endpoints. C. The AOS-10 Gateway cluster must be configured as the sole Route Reflector (RR), terminating all VXLAN tunnels from the wired edge switches directly. D. Central orchestrates EVPN-VXLAN overlay tunnels between fabric edge and border nodes via BGP EVPN control plane. Answer: D 12.A Network Architect is designing a high-density AOS-10 wireless network using ultra-tri-band APs. To support multi-gigabit throughput, the APs are connected to AOS-CX access switches using two physical Ethernet uplinks configured for Link Aggregation (LACP). [AOS-CX Switch - Port Configuration] interface lag 10 multi-chassis no shutdown no routing vlan trunk native 10 vlan trunk allowed 10,20,30 lacp mode active Which THREE statements accurately describe the operational behavior and tunnel orchestration dynamics of an AOS-10 AP utilizing LACP uplinks? (Select all that apply.) A. The AP will load-balance the tunneled IPsec traffic across both physical links by utilizing a proprietary payload-decapsulation hashing algorithm to bypass the switch's native LAG hashing. B. Central requires the administrator to manually define the MAC address of the upstream switch's LAG interface within the AP Group's uplink configuration to permit tunnel establishment. C. The AP utilizes the aggregated logical link to establish its single management IP and subsequently builds its high-throughput IPsec data tunnels to the Gateway cluster over this bonded connection. D. If LACP negotiation fails (e.g., switch misconfiguration), the AOS-10 AP will inherently fall back to an active/standby uplink model to ensure management connectivity to Central is not completely lost. E. The AOS-10 AP automatically negotiates LACP using standard 802.3ad protocols, meaning the upstream AOS-CX switch must have the two corresponding ports configured as an active LAG. Answer: C, D, E
