NEW QUESTION # 41
With the configuration oftwo CX 8325 switches in the VSX cluster, how would you prepare a link- aggregation for a 7000 gateway for a zero-touch provision to support protocol-based port redundancy?
- A.
- B.
- C.
- D.
Answer: A
Explanation:
The goal is to configure a Link Aggregation Group (LAG) on a VSX cluster (pair of CX 8325 switches) that connects to an Aruba 7000 series gateway undergoing Zero Touch Provisioning (ZTP). The LAG needs to support "protocol-based port redundancy" (LACP) and allow connectivity during ZTP.
* VSX Requirement:Since the LAG connects to two separate physical switches operating as a VSX pair, the LAG must be configured as a Multi-Chassis LAG (MC-LAG) on the switches. This allows the gateway to form a single LAG across both upstream devices. The command multi-chassis under the interface lag <id> context enables this.
* Protocol Redundancy Requirement:"Protocol-based port redundancy" indicates that Link Aggregation Control Protocol (LACP) should be used to dynamically negotiate and manage the LAG bundle between the switches and the gateway. The command lacp mode active enables LACP in active negotiation mode.
* ZTP Requirement:During ZTP, the gateway might not have its full configuration, including LACP settings, enabled immediately. To ensure the gateway can establish basic IP connectivity for ZTP (e.g., reach Activate/Central via DHCP/DNS), the switch ports should allow traffic even if LACP negotiation hasn't completed. The lacp fallback feature enables this, allowing individual LAG member ports to become active if LACP PDUs are not received from the peer.
* Analyzing the Options:
* A)Configures lacp mode active and lacp fallback butlacksthe multi-chassis command required for VSX.
* B)Correctly configures the LAG as multi-chassis, enables lacp mode active, and enables lacp fallback. This meets all requirements.
* C)Configures multi-chassis but uses potentially older or less standard syntax lacp enable and lacp fail-over instead of lacp mode active and lacp fallback.
* D)Lacks the multi-chassis command and uses potentially older/less standard syntax.
* Conclusion:Option B provides the complete and correct configuration using standard AOS-CX syntax to create an MC-LAG on the VSX pair with LACP enabled for redundancy and LACP fallback enabled to support gateway connectivity during ZTP.

NEW QUESTION # 42
An OSPF router has learned a path to an external network by both an E1 and E2 advertisement, both routes having the same path cost.
Which path will the router prefer?
- A. The router will prefer the E2 path.
- B. Both routes will be suppressed until the path conflict has been resolved.
- C. The router will use both paths equally my means of ECMP.
- D. The router will prefer the E1 path.
Answer: D
Explanation:
When both OSPF E1 (External Type 1) and E2 (External Type 2) routes exist to the same destination with equal cost, the router always prefers the E1 path. This is because E1 routes include both the external cost and the internal OSPF cost to reach the ASBR, making them more accurate for path selection.

NEW QUESTION # 44
Which issue may be causing the new door locks on the APs to not work?
- A. BT power to the AP is too much.
- B. AF power to the AP is not enough.
- C. AT power to the AP is not enough.
- D. AT power to the AP is too much.
Answer: B
Explanation:
802.3af (AF) PoE provides the least power. Many new devices, such as door locks attached to APs, require more power (AT or BT). If only AF power is provided, it's likely not enough for both the AP and the attached device.
NEW QUESTION # 45
Refer to the exhibit.
IGMP v3 was enabled on both VSX switches. Which switch becomes the IGMP querier forclients connected to Ace-1 switch?
- A. Agg-2
- B. both Agg-1 and Agg-2
- C. Agg-1
- D. Active gateway IP will be used as IGMP querier.
Answer: C
Explanation:
The setup has Agg-1 and Agg-2 as a VSX pair with IGMPv3 enabled. Ace-1 is a downstream switch connected to clients. The question asks which switch becomes the IGMP querier for clients connected to Ace-
1.
* IGMP Snooping & Querier:In a Layer 2 network using IGMP snooping, an IGMP querier is required on each VLAN to periodically send general queries. This prompts hosts to send membership reports, allowing snooping switches to learn which ports need which multicast streams.
* Querier Election:If multiple devices capable of querying exist on a VLAN (like routers or capable switches), an election occurs. Typically, the device with the lowest IP address on the VLAN becomes the querier.
* VSX & IGMP Querier:In an ArubaOS-CX VSX environment, the IGMP querier functionality is managed by the VSX pair. Documentation indicates that theprimary VSX switchtypically assumes the role of the IGMP querier for the VLANs it serves, including those extended via MC-LAG to downstream switches.
* Analysis of Options:
* A. Agg-2: Would only be the querier if it were the primary VSX switch.
* B. Both Agg-1 and Agg-2: Incorrect, only one active querier per VLAN is standard.
* C. Agg-1: Likely the primary VSX switch (often designated or wins election based on priority
/lower system MAC/IP) and thus becomes the querier.
* D. Active gateway IP: This is the virtual IP used for unicast routing, but the querier function runs on a physical switch, usually the primary.
* Conclusion:Assuming Agg-1 is the primary VSX switch (as is common convention or based on default election parameters if not explicitly configured), it will act as the IGMP querier for the VLAN serving clients connected to Ace-1.

NEW QUESTION # 47
Refer to the exhibit.
In the given example AGG-SW1 and AGG-SW2 use CX 8325 in VSX and Edge-1 with CX 6200F.
You want to avoid sub-optimal pathing and ISL traffic for the VSX and upstream routers R1 and R2.
What is the HPE Aruba Networking recommended solution for the SVIs on the VSX switches connected to R1 and R2?
- A. Configure the VSX SVI using the active-forwarding.
- B. Configure the VSX SVI using the VRRP virtual-ip.
- C. Configure the VSX SVI using the unicast IP.
- D. Configure the VSX SVI using the active-gateway.
Answer: D
Explanation:
In an AOS-CX VSX design, using active-gateway for SVIs ensures both VSX peers respond with the same virtual IP and virtual MAC. This avoids asymmetric routing, sub-optimal pathing, and prevents unnecessary ISL traffic between VSX peers. It is the HPE Aruba Networking recommended best practice for SVIs connected to upstream routers like R1 and R2.
NEW QUESTION # 48
Exhibit.
Acme Corp has VM workload running from ToR-1. and has noticed performancedegradation They suspect ToK-1 uplinks are periodically overutilized. List valid reasons whyToR-1 uplinks 3re being overutilized based on the diagram. (Select two.)
- A. Core-2 has been incorrectly configured as the root bridge
- B. ToR-1uplinks and downlinks are both running spanning-tree port-type admin-network.
- C. Thecustomer has used the default MSTP region configuration
- D. The VLAN to instance mapping is not the same on all switches.
- E. Core-1 and Core-2 are not running the same firmware
Answer: C,D
Explanation:
The question involves Acme Corp experiencing performance degradation due to overutilized uplinks from ToR-1 to Core-1 and Core-2, with a diagram (not provided) indicating a potential MSTP (Multiple Spanning Tree Protocol) issue. The task is to identify valid reasons for uplink overutilization.
* Analysis of Options:
* Option A:Incorrect. Incorrect root bridge configuration (e.g., Core-2 as root) may cause suboptimal paths but is not directly linked to uplink overutilization without further context.
* Option B:Correct. Inconsistent VLAN-to-instance mappings across switches can cause MSTP to block unexpected ports, funneling traffic through fewer uplinks and causing overutilization.
* Option C:Incorrect. Firmware mismatches may cause compatibility issues but are unlikely to directly cause uplink overutilization.
* Option D:Correct. Using the default MSTP region configuration (e.g., default region name and revision) across switches can lead to all switches forming a single MSTP region, potentially causing suboptimal topology and uplink overuse.
* Option E:Incorrect. Running MSTP with admin-network port-type on uplinks and downlinks is not a standard cause of overutilization; it's a specific port role.
* Why B and D are Correct:MSTP relies on consistent region configurations (region name, revision number, VLAN-to-instance mappings) to create efficient topologies. If VLAN-to-instance mappings differ (Option B), switches treat each other as separate regions, leading to blocked ports and traffic concentration on fewer uplinks, causing overutilization. Similarly, using the default MSTP region configuration (Option D) without customizing the region name or revision can result in all switches forming a single region with suboptimal spanning tree instances, potentially overloading specific uplinks. Both issues disrupt MSTP's ability to balance traffic across redundant paths, aligning with HPE Aruba Networking's MSTP troubleshooting scenarios.
* Relevance to Certification Objectives:
* Network Resiliency and Virtualization (8%):Troubleshooting MSTP for redundancy and fault tolerance.
* Switching (19%):Diagnosing Layer 2 issues, including MSTP misconfigurations.
* Performance Optimization (6%):Remediating uplink utilization issues.

NEW QUESTION # 49
You have recently configured a switch for 802.1X authentication with HPE Aruba Networking ClearPass. A security admin is seeing events with the following description in ClearPass Event Viewer.
'RADIUS authentication attempt from unknown NAD (10.10.1.10:1812)'
Which command should you use to identify the configuration issue?
- A. show aaa authentication-server radius
- B. show radius-server detail
- C. show radius-server shared-secret
- D. show ip source-interface radius
Answer: B
Explanation:
show radius-server detail will display the configured RADIUS servers along with their IP addresses and shared secrets. This helps you verify if the switch's management IP is properly registered as a NAD (Network Access Device) in ClearPass. If the IP used by the switch to send RADIUS requests is not listed as a NAD in ClearPass, you will see the "unknown NAD" error.
NEW QUESTION # 50
Refer to the exhibit.
You plan to replace a customer's old network equipment on AGG-SW1 and AGG-SW2 with CX
8325 in VSX and Edge-1 with CX 6200F. The customer's old network equipment is configured with industry-standard protocols. You want to migrate the gateway functionality that would be supported with the old equipment for a seamless failover.
Which first-hop protocol can you use?
- A. Configure the VSX SVI using active-forwarding and vMAC matching the existing MAC.
- B. Configure the VSX SVI using the VRRP matching VRID and virtual-ip.
- C. Configure the VSX SVI using the active-gateway and vMAC matching the existing MAC.
- D. Configure the VSX SVI using the unicast IP address and vMAC.
Answer: B
Explanation:
Since the old network equipment is using industry-standard protocols for first-hop redundancy, the correct migration path is to configure the new CX 8325 VSX pair with VRRP, matching the same VRID and virtual IP. This ensures seamless interoperability and failover without requiring proprietary features like VSX active-gateway.
NEW QUESTION # 51
A user cannot connect to the wired network using 802.1X with EAP-TLS. The user's device is configured correctly and the user has a valid certificate. The RADIUS server logs show that the user is authenticating successfully.
What could be the reason for this issue?
- A. The user's device is not using the correct certificate authority.
- B. The switch is not configured to use EAP-TLS.
- C. The RADIUS server is not configured to use EAP-TLS.
- D. There is an issue with the switch interface configuration.
Answer: D
Explanation:
Since the RADIUS logs show successful authentication with a valid certificate, EAP-TLS is functioning properly between the client and the RADIUS server. If the user still cannot connect, the issue is most likely with the switch interface configuration (e.g., missing VLAN assignment, incorrect role, or port-access settings), which prevents network access after successful authentication.
NEW QUESTION # 52
Two CX 8325 switches are configured as a cluster using VSX for the core role and two CX
6300M in VSF for the aggregation role. When a major software upgrade is issued on the switches, what is the method to achieve a hitless upgrade with the core switches?
- A. ISSU update-software initiates the upgrade first on the primary switch, followed by the secondary
- B. VSX update-software initiates software upgrade first on the primary switch, followed by the secondary
- C. ISSU update-software initiates the upgrade first on the secondary switch, followed by the primary
- D. VSX update-software initiates software upgrade first on the secondary switch, followed by the primary
Answer: D
Explanation:
On AOS-CX VSX pairs, a hitless upgrade is performed using the vsx update-software command.
This process always starts with the secondary switch first, ensuring minimal disruption. Once the secondary is upgraded and resynchronized, the primary switch is upgraded. This preserves control plane stability and forwarding continuity during the upgrade.

- D. AIOps integrated into HPE Aruba Networking Central
Answer: D
Explanation:
AIOps in HPE Aruba Networking Central provides AI/ML-driven analytics, automated troubleshooting, and proactive insights. This gives clients better visibility and automates the process of detecting, analyzing, and resolving issues, which is exactly what the client is asking for.
NEW QUESTION # 54
Which issue may becausing the new door locks on the APs to notwork?
- A. BT power to the AP is too much.
- B. AF power to the AP is not enough.
- C. AT power to the AP is too much.
- D. AT power to the AP is notenough.
Answer: B
Explanation:
New PoE-powered door locks, connected via the PoE passthrough port on Aruba APs, are not working. We need to find the likely cause related to PoE power.
* PoE Passthrough:An AP feature where the AP, powered by PoE from a switch, provides PoE power out to another device connected to one of its Ethernet ports.
* Power Budget:The AP must receive enough power from the switch via its PoE input (e.g., 802.3af,
802.3at, 802.3bt) to power itselfandmeet the power demand of the downstream device (the door lock).
* PoE Standards Power (Approx. Available to Device):
* 802.3af (PoE): ~13 Watts
* 802.3at (PoE+): ~25.5 Watts
* 802.3bt (PoE++): 51W (Type 3) or 71W (Type 4)
* Analysis:Modern APs (especially Wi-Fi 6/6E) can consume significant power themselves (>15W or
>25W under load). Standard 802.3af PoE (supplying only ~13W) is often insufficient to power both a modern AP and a downstream PoE device like a door lock. The AP will power up, but won't enable PoE output if its input power budget is insufficient.
* Analysis of Options:
* A, B: Too much power (AT/BT) isn't the issue; devices only draw what they need.
* C: AF power (~13W) received by the AP is very likelynot enoughto power both the AP and the door lock.
* D: AT power (~25.5W)mightbe insufficient if the combined load of the AP and lock exceeds this, but AF being insufficient (C) is a more common limitation.
* Conclusion:Insufficient input power to the AP is the most common reason for PoE passthrough failure.
802.3af (PoE) power is often inadequate.
References:IEEE 802.3 PoE standards (af/at/bt), Aruba Access Point datasheets (PoE requirements, passthrough capabilities/budgets). This relates to "WLAN" (9%) and "Connectivity" (9%) objectives.
NEW QUESTION # 55
A customer is trialing the below colorless port configuration on a single switch and has noticed that users roaming to access points connected to the test switch are unable to receive an IP address on the corporate Wi-Fi network, which is operating in bridged mode. All other SSIDs are working as expected and the AP is Online in HPE Aruba Networking Central.
The security team reports that there have been no failed authentications in HPE Aruba Networking ClearPass Access Tracker and that the last entry for the wired port is returning the REDIUS Aruba-User-Role attribute 'Access_Point'.
Which configuration change is required to resolve the issue?
port-access client-move enable
- A. aaa authentication port-access client-limit 0
- B. port-access role Access_Point
- C. port-access onboarding-method concurrent enable
interface 1/1/1-1/1/48 - D. auth-mode device-mode
interface 1/1/1-1/1/48
Answer: D
Explanation:
For AP uplinks carrying bridged SSIDs, the switchport must authenticate only the AP and then treat all client MACs as part of the same trusted device. Enabling auth-mode device-mode under the Access_Point port-access role ensures the AP is authenticated (MAC-auth), the trunk is applied, and the switch does not attempt to re-authenticate wireless client MACs - allowing clients on the corporate SSID to obtain IP addresses.
NEW QUESTION # 56
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. There is a problem with the ACL applied to the switch port.
- B. The user's device is not configured to use the correct gateway.
- C. The user's device is using the wrong MAC address.
- D. The NAD is not able to communicate with DNS servers.
- E. There is an EAP-type mismatch.
Answer: A,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.
NEW QUESTION # 57
Refer to the exhibit.
A gateway cluster needs to be connected to the VSX-enabled switches where MC-LAG is configured. What is a possible constraint?
- A. The command lacp fallback is missing on the interface lag level.
- B. lacp mode active needs to be configured on the gateways when using "static-activate" mode.
- C. LACP is not supported during the initial provisioning and needs to be turned off.
- D. LLDP needs to be enabled to detect LACP-configured interfaces.
Answer: C
Explanation:
When connecting a gateway cluster to VSX-enabled switches with MC-LAG, LACP cannot be used during the initial provisioning phase (ZTP/OTP). You must use static port-channeling (no LACP) for the first setup. Once provisioning is complete, you can re-enable LACP. This is a documented constraint for initial gateway provisioning with Aruba gateways.
NEW QUESTION # 58
Refer to thefour numbered steps in theexhibit.
Which action is the first step in applying a role-to-role ACL on thetraffic from mobile device M1 to role H2?
- A. The AP forwards the pocket from M1 to gateway 1.
- B. The edge switch acts as the intermediate node and transfers theGroup Policy ID over static VXLAN to dynamic VXLAN tunnel and forwards the packet to switch A1.
- C. Switch A1 determines the destination role based on destination MAC or destination IP and enforces role-to-role ACLs.
- D. Gateway 1 forwards the traffic over the static VXLAN tunnel to the edge switch, this packet carries the Group Policy ID corresponding to the role of M1.
Answer: A
Explanation:
The question asks for the first step in applying a role-to-role ACL (Access Control List) on traffic from a mobile device (M1) to a role (H2) in a network using Dynamic Segmentation with VXLAN and role-based policies.
* Analysis of Options:
* Option A:Describes an intermediate step where the edge switch transfers the Group Policy ID over VXLAN, which occurs later in the process.
* Option B:Correct. The first step is the AP forwarding the packet from the mobile device (M1) to the gateway, which initiates the traffic flow in a tunneled Dynamic Segmentation setup.
* Option C:Describes a later step where the destination switch (A1) enforces the role-to-role ACL, after the packet has traversed the network.
* Option D:Describes a step where the gateway forwards traffic over a VXLAN tunnel, which occurs after the AP forwards the packet.
* Why Option B is Correct:In HPE Aruba Networking's Dynamic Segmentation architecture, wireless clients (e.g., M1) connect to an AP, which tunnels traffic to a gateway (e.g., in tunneled mode). The first step in the traffic flow is the AP forwarding the client's packet to the gateway, which then processes the packet for role assignment and policy enforcement. This aligns with the role-to-role ACL application process, where the gateway applies policies based on the source (M1's role) and destination (H2's role) using Group Policy IDs over VXLAN.
* Relevance to Certification Objectives:
* Security (10%):Involves designing and troubleshooting role-based security policies in customer networks.
* WLAN (9%):Includes implementing and troubleshooting wireless traffic flows in Dynamic Segmentation.
* Switching (19%):Covers Layer 2/3 interconnection technologies like VXLAN for policy enforcement.

NEW QUESTION # 59
The customer is experiencing periodic uplink congestion between campus-1's AGG-1 and core.
This has been negatively affecting voice communications. The VoIP phones edge mark packets with DSCP EF. The uplink from AGG-1 to core is LAG1.
The customer has already configured the following class and policy on AGG-1:
Based on this policy, which script, when deployed on AGG-1, will improve the reliable forwarding of voice traffic between AGG-1 and its uplink to the core?
- A.
- B.
- C.
- D.
Answer: A
Explanation:
The policy already classifies VoIP traffic (DSCP EF) and sets local-priority 6. To ensure reliable forwarding during congestion, that traffic must be mapped into a strict priority queue on the uplink (LAG1). Script A configures queue 7 as a strict priority queue with a bandwidth limit, and applies the schedule profile to LAG1, ensuring voice traffic is dequeued before other traffic. This guarantees low latency and jitter for VoIP.
