NEW QUESTION # 39
When trying to add a now access switch to the network, theswitch port at the aggregation switch is automatically disabled.
What needs to be done to fix this issue?
- A. Disable spanning tree bpdu-tilter al the interface level.
- B. Disable spanning tree bpdu-guard at the interface level.
- C. Disable spanning tree root-guard at the interface level.
- D. Disable spanning tree loop-guard at the interface level.
Answer: B
Explanation:
The issue involves a new access switch's port being automatically disabled when connected to an aggregation switch, likely due to a Spanning Tree Protocol (STP) protection mechanism.
* Analysis of Options:
* Option A (Disable bpdu-filter):BPDU filtering prevents BPDUs from being sent or processed, which could cause loops, not resolve the issue.
* Option B (Disable root-guard):Root guard prevents a port from becoming the root bridge but does not cause port disablement in this context.
* Option C (Disable loop-guard):Loop guard prevents alternate ports from becoming designated but is unrelated to port disablement.
* Option D:Correct. Disabling BPDU guard on the aggregation switch's interface prevents it from disabling the port when it receives BPDUs from the new access switch.
* Why Option D is Correct:BPDU guard is an STP feature that disables a port if it receives BPDUs, assuming an unauthorized device is connected. When a new access switch isconnected, it sends BPDUs as part of normal STP operation, triggering BPDU guard on the aggregation switch and disabling the port. Disabling BPDU guard on the aggregation switch's interface (e.g., no spanning-tree bpdu-guard) allows the access switch to participate in STP without being disabled, resolving the issue while maintaining network stability.
* Relevance to Certification Objectives:
* Network Resiliency and Virtualization (8%):Involves troubleshooting STP mechanisms for fault tolerance.
* Troubleshooting (10%):Includes diagnosing and remediating STP-related issues in campus networks.
* Switching (19%):Covers Layer 2 technologies like STP and its protection features.

NEW QUESTION # 42
A Python developer was able to read but could not modify the VLAN database on an AOS-CX switch through the REST API.
Which settings should the developer check first? (Choose two.)
- A. SSH settings
- B. SNMP settings
- C. REST API settings
- D. HTTPS settings
- E. cookie settings
Answer: C,D
Explanation:
HTTPS settings → Required because the AOS-CX REST API runs over HTTPS. If HTTPS is not enabled, write operations will fail.
REST API settings → Must be checked to ensure that the REST API write mode (read/write vs.
read-only) is enabled.
NEW QUESTION # 43
Exhibit.
VSX cluster is already configured. Your task is to validate a correct configuration for the Edge-1 switch that is connected to a CCTV provider that will install its switching infrastructure. The CCTV switches do not support STP.
What needs to be configured on the Edge-1 switch ports connecting to CCTV-SW1 and CCTV-SW2 to prevent loop problems with the existing setup with automatic recovery features?
- A. configure lag with lacp fallback for CCTV switch ports
- B. configure spanning-tree with udld for CCTV switch ports
- C. configure spanning-tree with bpdu-guard timeout values for CCTV switch ports
- D. configure spanning-tree and TCN-guard timeout for CCTV switch ports
Answer: C
Explanation:
The requirement is to prevent loops on Edge-1 switch ports connected to third-party CCTV switches that do notsupport STP. The solution must also include an automatic recovery feature if a port gets disabled.
* Loop Prevention without STP:When connecting to non-STP devices, standard STP loop prevention (like BPDU Guard) might not work if the connected device doesn't send BPDUs. AOS-CX offers a feature called loop-protect which sends probes to detect loops in non-STP environments.
* Automatic Recovery:Features that disable ports (like BPDU Guard or Loop Protect) often have a timeout or auto-recovery option (port-disable-timer for Loop Protect) allowing the port to automatically re-enable after a configured period.
* Analysis of Options:
* A: LACP fallback applies to LAGs, not general loop prevention.
* B: TCN-guard is an STP feature, irrelevant here.
* C: Suggests spanning-tree with bpdu-guard timeout. BPDU Guard detects loops by listening for BPDUs, which these CCTV switches don't send. However, the timeout featuredoesprovide the required automatic recovery mechanism if the portweredisabled by BPDU Guard.
* D: UDLD detects unidirectional links, not typically bridging loops caused by topology.
* Re-evaluation:The ideal AOS-CX feature is loop-protect with port-disable-timer. Since this isn't explicitly an option, we must evaluate the given choices. Option C is theonlyone that mentions a mechanism (bpdu-guard timeout) providing automatic recovery from a disabled state. While BPDU Guard isn't the right detection mechanism here, it's the closest fit regarding the auto- recoveryrequirement. It's possible the question implicitly assumes some stray BPDUs might trigger it or that it's the intended "best fit" answer despite the detection mechanism mismatch.
* Conclusion:Given the options, Option C is the most plausible because it includes the timeout feature associated with bpdu-guard, fulfilling the automatic recovery requirement, even though BPDU guard itself is not the ideal detection method for loops involving non-STP devices.

NEW QUESTION # 44
Exhibit.
After Implementing a distributed overlay with distributed anycast gateways, you noticed that toomany ARP packets are being replicated to every access (leaf) switch Which command can you use to optimize the network?
- A. interface vlan 10 ip proxy-arp interface vlan 11 ip proxy-arp
- B. evpn ip proxy-arp
- C. evpn arp-suppression
- D. vlan 10 arp-suppression vlan 11 arp-suppression
Answer: C
Explanation:
In an EVPN VXLAN distributed overlay network, excessive ARP packet replication (flooding) to all leaf switches is observed. We need the command to optimize this.
* EVPN ARP Optimization:EVPN uses its control plane (BGP) to distribute MAC and IP address reachability information. Leaf switches (VTEPs) learn these mappings. To reduce ARP flooding across the VXLAN fabric:
* ARP Suppression:VTEPs intercept ARP requests. If the VTEP already knows the MAC address for the requested IP (learned via EVPN), it can suppress the ARP request, preventing it from being flooded over VXLAN.
* Proxy ARP:VTEPs intercept ARP requests. If the VTEP knows the MAC for the requested IP, it can generate an ARP replyon behalfof the remote host.
* AOS-CX Commands:These features are configured within the EVPN context.
* evpn arp-suppression (B): Enables the ARP suppression feature for EVPN.
* evpn ip proxy-arp (C): Enables the proxy ARP feature for EVPN.
* Options A and D use standard interface/VLAN level arp-suppression or proxy-arp commands, which are not specific to optimizing flooding within the EVPN VXLAN fabric itself.
* Conclusion:To optimize by reducing the replication/flooding of ARP packets across the EVPN VXLAN overlay, enabling evpn arp-suppression (Option B) is the direct command. This leverages the EVPN control plane knowledge to stop unnecessary ARP flooding.

(Snippet 1)
* Identify individual layer 2 segments in an overlay -->
vni 11
vtep-peer 10.1.0.5
vlan 11
(Snippet 3)
Comprehensive Detailed Explanation along with All References available from related to the HPE Campus Access Switching Expert certification objectives at end of each question below:
* Aggregate links across multiple switches:This requirement describes Multi-Chassis Link Aggregation (MC-LAG), where a device forms a LAG to two separate upstream switches that act as a logical pair. In AOS-CX, VSX (Virtual Switching Extension) enables this functionality. Snippet 4 shows commands related to setting up VSX (vsx, role primary, inter-switch-link, keepalive), which is the foundation for MC-LAG.
References:AOS-CX VSX Guide.Relates to "Network Resiliency and virtualization" (8%), "Switching" (19%).
Establish redundant links between the aggregation and core layers:This often involves Layer 3 routing protocols utilizing multiple paths. Snippet 2 (router ospf 1, maximum-paths 2) configures OSPF to use up to two Equal Cost Multi-Paths (ECMP). If redundant links between aggregation and core result in equal OSPF costs, this command enables load sharing and redundancy at Layer 3.
References:AOS-CX IP Routing Guide (OSPF, ECMP). Relates to "Routing" (16%), "Network Resiliency and virtualization" (8%).
Extend layer 2 across multiple sites:VXLAN (Virtual Extensible LAN) is the standard overlay technology for extending Layer 2 segments over an underlying Layer 3 network, enabling L2 adjacency across different physical locations (sites, racks, pods). Snippet 1 shows the basic configuration of a VXLAN tunnel interface (interface vxlan 1, source ip), which is the core component for VXLAN tunneling.
References:AOS-CX VXLAN Guide.Relates to "Switching" (19%), "Connectivity" (9%).
Identify individual layer 2 segments in an overlay:Within a VXLAN overlay, each separate Layer 2 broadcast domain (typically corresponding to a VLAN) is identified by a unique VXLAN Network Identifier (VNI). This VNI tags the encapsulated traffic. Snippet 3 shows the configuration associating VNI 11 with the local VLAN 11 (vni 11, vlan 11). The vtep-peer command is relevant when using EVPN as the control plane.
This configuration directly maps an L2 segment (VLAN 11) to its identifier (VNI 11) within the overlay.

NEW QUESTION # 47
Which is a best practice for configuringGBP?
- A. Use static user roles (SUR) to configure GBP
- B. Configure GBP classes to have a destination role that is the same as the associated user rote.
- C. Configure GBP classes to have a destination role that is different from theassociated user role.
- D. Use downloadable user roles (DUR) to configure GBP.
Answer: D
Explanation:
The question asks for a best practice when configuring Group-Based Policy (GBP). GBP simplifies policy management by assigning users/devices to roles and defining policies between these roles, often leveraging dynamic assignment from an authentication server.
* GBP Concepts:Policies are typically defined based on source and destination roles. Roles can be assigned statically on the switch or dynamically via an authentication server like ClearPass.
* Analysis of Options:
* A & C: Policies define interactionsbetweenroles (source role to destination role). These roles can be the same (intra-role policy) or different (inter-role policy). Neither option represents a singular
"best practice" for all configurations.
* B: Using Static User Roles (SUR) is possible but less flexible and scalable than dynamic assignment for large or complex environments.
* D: Using Downloadable User Roles (DUR) is generally considered a best practice. DUR allows roles and associated policies (including GBP attributes like GPID) to be centrally defined on an authentication server (e.g., ClearPass) and dynamically assigned to users/devices uponsuccessful authentication. This provides scalability, consistency, and easier management.
* Conclusion:Leveraging Downloadable User Roles (DUR) from a central authentication server like ClearPass is a best practice for implementing scalable and manageable Group-Based Policies.

NEW QUESTION # 49
Which tables arc synchronized between a pair ofCX 8325 switches in a VSX cluster? (Select two.)
- A. Spanning-TreeProtocol (STP)
- B. IP Routing
- C. Link Layer Discovery Protocol (LLDP)
- D. BGP Neighbors
- E. MAC address
Answer: B,E
Explanation:
The question asks which tables are synchronized between a pair of CX 8325 switches in a Virtual Switching Extension (VSX) cluster. VSX is a high-availability solution that synchronizes specific tables to ensure consistent operation across both switches.
* Analysis of Options:
* A. BGP Neighbors:BGP neighbor tables are not synchronized in VSX; each switch maintains its own BGP sessions.
* B. MAC address:Correct. VSX synchronizes the MAC address table to ensure consistent Layer
2 forwarding across both switches.
* C. Spanning-Tree Protocol (STP):STP states are not synchronized; each switch runs its own STP instance, though they coordinate to avoid loops.
* D. IP Routing:Correct. VSX synchronizes the IP routing table to ensure consistent Layer 3 forwarding.
* E. Link Layer Discovery Protocol (LLDP):LLDP information is not synchronized; each switch maintains its own neighbor information.
* Why B and D are Correct:In a VSX cluster, the MAC address table and IP routing table are synchronized to ensure seamless Layer 2 and Layer 3 operations. This synchronization allowsboth switches to share a common view of the network, enabling features like active-active forwarding and hitless failover. The vsx-sync feature in AOS-CX ensures these tables are kept consistent across the VSX pair.
* Relevance to Certification Objectives:
* Network Resiliency and Virtualization (8%):Involves designing and troubleshooting VSX for resiliency and redundancy.
* Switching (19%):Includes implementing and troubleshooting Layer 2 technologies like MAC address tables.
* Routing (16%):Covers IP routing table synchronization in VSX environments.

HPE Aruba Networking AOS-CX Configuration Guide: VSX Configuration, detailing table synchronization.
HPE7-A06Study Guide: Covers VSX architecture and synchronization mechanisms.
HPE Aruba Networking Technical Documentation: VSX Overview, explaining MAC and routing table synchronization.
VSX (Virtual Switching Extension) synchronizes state information between the two switches in a cluster to enable active-active forwarding and provide a single logical view to downstream devices.
Analysis of Options:
A: BGP Neighbors: BGP sessions are typically established independently by each VSX member. While configurations can be synced, the dynamic state/neighbor table itself is not a core VSX synchronization item.
B: MAC address: The MAC address table is synchronized between VSX members. This is crucial for Layer 2 forwarding consistency and allowing either switch to forward traffic destined for a known MAC address learned via the VSX pair.
C: Spanning-Tree Protocol (STP): STP runs independently on each physical switch. VSX uses technologies like MC-LAG to provide loop-free active-active paths downstream, reducing reliance on STP blocking, but the STP state itself isn't synchronized via the ISL.
D: IP Routing: While the full IP routing table (RIB) is built independently on each switch via routing protocols, VSX Active Gateway synchronizes necessary Layer 3 information (like virtual gateway IP and MAC, and potentially ARP entries) to ensure consistent first-hop routing and failover. Some sources might broadly categorize ARP synchronization under L3/IP routing context in VSX. Given that the ARP table (essential for L3 forwarding consistency) is synchronized, and it's not listed separately, "IP Routing" might encompass this synchronization aspect.
E: Link Layer Discovery Protocol (LLDP): LLDP information relates to physically connected neighbors of each switch and is not synchronized across the VSX ISL.
Conclusion: The MAC address table (B) is definitively synchronized. The ARP table is also synchronized, which is fundamental for Layer 3 forwarding consistency provided by Active Gateway. As ARP is not explicitly listed, and "IP Routing" (D) is, D is the most likely second answer intended to cover the necessary L3 state synchronization (primarily ARP and Active Gateway state) performed by VSX.

NEW QUESTION # 50
Which setof commands willapply the device profile 'AP'to the device shown in the LLDP neighbor output below?
- A.
- B.
- C.
- D.
Answer: A
Explanation:
The goal is to configure the switch to automatically apply a specific device profile (named AP-PROFILE in the options) to ports where an Aruba AP Model 635 connects, using LLDP information for detection.
* LLDP Information:The LLDP neighbor output shows:
* Neighbor Chassis-Description: ArubaOS (MODEL: 635), Version Aruba AP
* Neighbor Chassis-Name: AP-42
* Device Profile Mechanism:This involves creating an LLDP group that matches specific attributes of the desired device, creating a device profile containing the desired port configurations (VLAN, PoE, QoS, Role, etc.), associating the profile with the LLDP group, and enabling the feature globally.
* Analyzing Configuration Options:All options configure an LLDP group AP-LLDP-GROUP and a device profile AP-PROFILE. The key is the matching condition within the LLDP group and the completeness of the profile configuration.
* Matching Condition:
* Options A, C, D use seq 10 match sys-desc 635. This condition checks if the LLDP System Description contains the string "635". Based on the output (...MODEL: 635...), this conditionwill matchthe target AP.
* Option B uses seq 10 match sys-name 635. This checks if the LLDP System Name contains
"635". The output shows Neighbor Chassis-Name: AP-42. This conditionwill not match.
NEW QUESTION # 51
Refer to the exhibit.
Based on the screenshot, what is required to correct the state displayed in the exhibit?
- A. Use the force vsx-sync to start sync process.
- B. Use the same OS-CX image on the secondary that is active on primary.
- C. Use copy running-config vsx-peer on the secondary switch.
- D. Use the Enhanced Software Update process to correct the state.
Answer: B
Explanation:
The exhibit shows that the VSX config-sync is non-operational with the error state SW version mismatch. This occurs when the primary and secondary switches are running different ArubaOS- CX software versions. To correct this, both peers must run the same OS-CX image. The recommended remediation explicitly suggests running show images to confirm the software image and ensure the same version is loaded on both peers.
NEW QUESTION # 52
A pair of CX 8325 series switches is configured in a VSX cluster. Which function is executed on both VSX members during normal operation?
- A. periodically sends gratuitous ARP and broadcast hello packets
- B. replies to ARP requests with the cluster vMAC
- C. routes PIM and PIM-DR
- D. relays DHCP requests or servers DHCP offer
Answer: C
Explanation:
In an AOS-CX VSX cluster, both members act as independent routing and multicast-capable devices. Each VSX node maintains its own control plane, so both members can independently perform functions like routing, running PIM, and acting as PIM Designated Router (PIM-DR).
Other functions, such as ARP replies with the cluster vMAC or gratuitous ARPs, are handled by the active gateway only, not both switches.
NEW QUESTION # 53
Refer to the exhibit.
Acme Corp has VM workload running from ToR-1, and has noticed performance degradation.
They suspect ToR-1 uplinks are periodically overutilized.
List valid reasons why ToR-1 uplinks are being overutilized based on the diagram. (Choose two.)
- A. The VLAN to instance mapping is not the same on all switches.
- B. The customer has used the default MSTP region configuration.
- C. Core-1 and Core-2 are not running the same firmware.
- D. Core-2 has been incorrectly configured as the root bridge.
- E. ToR-1 uplinks and downlinks are both running spanning-tree port-type admin-network.
Answer: A,B
Explanation:
With default MSTP region settings, devices form different regions, so only the CIST participates across them. This removes per-instance load-sharing and pushes all VLANs over a single active uplink, overutilizing it.
If VLAN-to-instance mappings differ between switches, MSTP instances don't align end-to-end, so VLANs cannot split paths per instance and converge onto one uplink, causing periodic overutilization.
NEW QUESTION # 54
The user's device a failing 802.1X with EAP-TLS authentication. We know that the client-side certificate is valid. What is the likely cause of this issue? (Choose two.)
- A. The NAD is not able to communicate with DNS servers.
- B. The user's device is not configured to use the correct gateway.
- C. There is a problem with the ACL applied to the switch port.
- D. The user's device is using the wrong MAC address.
- E. There is an EAP-type mismatch.
Answer: C,E
Explanation:
A restrictive ACL on the switch port can block required authentication or EAP traffic, causing
802.1X failure.
An EAP-type mismatch between client and network (for example, if the switch or RADIUS is not configured for EAP-TLS) will also cause authentication to fail, even if the certificate is valid.
