NEW QUESTION # 12
A Windows device attempts to connect to an 802.1X network but it is not receiving the correct role. TEAP has been configured asthe only authentication method in ClearPass.The wireless configuration is correct.
Exhibit.
What is me mostlikelycause?
- A. The Windows device needs 10 De configured tor TEAP.
- B. 802.1X is not compatible with TEAP in windows device
- C. ClearPass requires a second authentication method.
- D. Only machine authentication should be configured on the Windows device
Answer: A
Explanation:
The issue likely stems from the Windows device not being configured to use TEAP (Tunneled Extensible Authentication Protocol) as specified in the ClearPass configuration. TEAP is an EAP method that encapsulates an inner EAP method for secure authentication. The Windows device must have TEAP enabled and correctly configured in its network settings to authenticate successfully on the network using ClearPass.
NEW QUESTION # 13
Your customer added third-party USB dongles to the USB ports of their AOS 10 access points. The customer uses AP-615 and AP-635 Each AP is connected with a Cat 6A cable to a CX 6300F Class 4 PoE switch All APs are in the same group in HPE Aruba Networking Central and share the same configuration However, many of the dongles do not come up.
Which option will solve this issue?
- A. Replace the Class a PoE switches with Class 6 PoE switches.
- B. Move the AP-635 access points to a different group in Central to configure the dongles separately from the AP-615.
- C. Create two separate service profiles in the loT tab of the Central configuration settings.
- D. Perform a "poe disable" followed by a "poe enable" for the switch ports which connect to the APs so that the APs reboot.
Answer: A
Explanation:
USB dongles often require additional power, which may exceed the power delivery capabilities of Class 4 PoE switches. Aruba AP-615 and AP-635 are designed to work with USB dongles that require additional power for proper operation. Since the Cat 6A cable can support higher power levels, replacing the Class 4 PoE switches with Class 6 PoE switches, which can deliver higher power, should resolve the issue with the dongles not powering up.
NEW QUESTION # 14
What is me recommended configuration to ensure link aggregation is consistent in a campus topology using VSX with two aggregation switches and downlinks to access switches?
- A. Use the command "vsx-sync active-gateways" under the VSX context.
- B. Use the command "vsx-sync mclag-interfaces" under the VSX context.
- C. Keep the MTU values at the default setting for GRE and VXLAN communications
- D. Use a custom LACP hash algorithm for improved load Balancing.
Answer: B
Explanation:
When configuring Virtual Switching Extension (VSX) in a campus topology for link aggregation across two aggregation switches, it is important to synchronize Multi-Chassis Link Aggregation Group (MC-LAG) interfaces. The command "vsx-sync mclag-interfaces" ensures that the state and configuration of MC-LAG interfaces are synchronized between the two VSX-linked switches,providing consistent link aggregation and preventing any loops or mismatched configurations that might occur if the interfaces were not in sync.

A BGP routing tablecontains multiple routes to the same destination prefix.
Referring to the table below whichroutewould be marked with a ">" symbol?
- A. Option E
- B. Option D
- C. Option C
- D. Option A
- E. Option B
Answer: A
Explanation:
In BGP, the route marked with a ">" symbol is the best route that is chosen based on BGP attributes in the following order: highest weight (Cisco-specific), highest local preference, originated by BGP running on the local router, shortest AS path, lowest origin type, lowest MED, eBGP over iBGP, closest IGP neighbor, and lowest BGP router ID. Based on the table provided, Option E would be marked with a ">" symbol as it has the highest local preference of 100 which is a decisive factor in the BGP best path selection process.
NEW QUESTION # 17
Exhibit.
You updated your gateway to me most recent firmware However after the firmware was updated, the gateway could no longer connect to HPE Aruba Networking Central. Your corporate ITIL procedures require you to implement your backout plan. You connected a console cable to your gateway and saw the following prompt.
Cpxload#
in what order, do you need to execute the following commands to return to the previous firmware version?
Answer:
Explanation:
Explanation:
The sequence to return to the previous firmware version after an unsuccessful update would typically be:
hit any key to stop autoboot(This would prevent the system from automatically booting into the current, problematic firmware.) def_part 1(This command sets the default boot partition, which is likely where the previous working firmware is located.) bootf(This command would boot from the specified flash partition, which after the second step, would be the previous firmware.) osinfo(After the system is booted, this command could be used to confirm the firmware version now running on the gateway.)
NEW QUESTION # 18
A customer's infrastructure is set up to use both primary and secondary gateway clusters on the SSID profile cased on best practices. Why do they have an equal split of their 120 APs across the primary and secondary gateway clusters?
- A. The secondary gateway cluster is a homogeneous cluster with six nodes.
- B. The primary and secondary gateway clusters are up. and the cluster preemption is enabled
- C. The primary gateway cluster is a heterogeneous cluster with six nodes.
- D. The primary and secondary gateway clusters are up. but the cluster preemption Is not enabled
Answer: D
Explanation:
When cluster preemption is not enabled, access points (APs) will not automatically fail back to the primary gateway cluster once it is up again after having failed over to the secondary. This would result in an equal split of APs across primary and secondary clusters if both clusters are operational. Without preemption, there's no automatic rebalancing of APs back to the primary cluster, leading to the current distribution.
NEW QUESTION # 19
You recently added HPE Aruba Networking ClearPass as an authentication server to a group in HPE Aruba Networking Central. RADIUS authentication with Local User Roles (LUR) works fine, but the same access points cannot use Downloadable User Roles (DUR).
What should be corrected in this configuration to fix the issue with DUR?
- A. Modify the shared secret on the switch to match CPPM using the "radius-server host" command
- B. Add a new Enforcement Policy of type "WEBAUTH" on ClearPass and associate it with the matching service on ClearPass
- C. Uncheck the "Dynamic Authorization" checkbox in the authentication server configuration on HPE Aruba Networking Central
- D. Add the correct values for "CPPM Username" and "CPPM Password" in the authentication server configuration on HPE Aruba Networking Central
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract of HPE Aruba Networking Switching:
When using Downloadable User Roles (DUR) with HPE Aruba Networking ClearPass, the Aruba device (AP, gateway, or switch) must authenticate to ClearPass to retrieve and install the user role that ClearPass sends dynamically. This process differs from normal RADIUS authentication, where only the user credentials are verified.
In Aruba Central, when you configure an authentication server (ClearPass) and enable Downloadable Roles
, the system requires CPPM Username and CPPM Password fields. These credentials are specifically used by the Aruba device to establish a secure HTTPS (TLS) session to the ClearPass server for DUR retrieval.
If the CPPM Username or CPPM Password values are missing, incorrect, or not synchronized with the corresponding credentials defined on ClearPass, the device will fail to authenticate to ClearPass for DUR retrieval. This results in RADIUS authentication succeeding (because LUR is still functioning), but the DUR cannot be downloaded.
Exact Extract from HPE Aruba Networking Switching and ClearPass Configuration Guides:
"When Downloadable User Roles are enabled, the Aruba device must authenticate with ClearPass using configured credentials. The device uses the CPPM Username and Password for HTTPS-based role retrieval. If the credentials are not defined or are invalid, role download will fail even if RADIUS authentication succeeds."
"The CPPM Username and Password define the credentials the device uses to connect to ClearPass for downloadable role retrieval. These credentials must match the admin or API credentials configured on the ClearPass Policy Manager server." This explains why Local User Roles (LUR) work (standard RADIUS), but Downloadable User Roles (DUR) do not - the HTTPS/TLS authentication for DUR fails because the required credentials were not configured correctly.
Why the Other Options Are Incorrect:
* A. Add a new Enforcement Policy of type "WEBAUTH" on ClearPass:WebAuth enforcement policies are unrelated to DUR. Downloadable User Roles are delivered using an Aruba Downloadable Role enforcement profile, not WebAuth.
"Downloadable roles are defined and enforced through the Aruba Downloadable Role profile type. WebAuth policies are used for captive portal authentication only."
* C. Uncheck the "Dynamic Authorization" checkbox:Dynamic Authorization (RFC 3576 or CoA) allows session reauthentication or role changes. Disabling this feature would not fix DUR, as DUR relies on CPPM credentials for HTTPS authentication.
"Dynamic Authorization (CoA) enables session updates but does not control role download authentication."
* D. Modify the shared secret on the switch using the 'radius-server host' command:This option applies to switch RADIUS configuration, not Aruba Central APs or gateways. The DUR process uses HTTPS with ClearPass credentials, not the RADIUS shared secret.
"The RADIUS shared secret is used for authentication requests, not for downloadable role retrieval.
Downloadable roles require valid CPPM credentials."

NEW QUESTION # 20
A customer's infrastructure is set up to use both primary and secondary gateway clusters on the SSID profile based on best practices. Why do they have an equal split of their 144 APs across the primary and secondary gateway clusters?
- A. The primary and secondary gateway clusters are up, and the cluster preemption is enabled.
- B. The secondary gateway cluster is a homogeneous cluster with six nodes.
- C. The secondary gateway cluster is a heterogeneous cluster with four nodes.
- D. The primary and secondary gateway clusters are up, but the cluster preemption is not enabled.
Answer: D
Explanation:
Comprehensive and Detailed Explanation (Verified Extract from HPE Aruba Networking AOS-10 Gateway and Cluster Design Documentation) When primary and secondary gateway clusters are defined in an SSID profile in AOS-10, the Access Points (APs) dynamically distribute their tunnel termination sessions based on the availability of both clusters.
If both clusters are operational and cluster preemption is not enabled, the APs maintain their current session distribution, resulting in an approximately equal split of AP tunnels across both clusters.
Aruba Documentation Extract:
"When both primary and secondary gateway clusters are reachable and cluster preemption is disabled, APs remain distributed across both clusters to maintain balance and prevent disruption."
"Cluster preemption, if enabled, causes APs associated with the secondary cluster to move back to the primary cluster once it becomes available, consolidating tunnel load." Thus:
* The equal split (72 APs per cluster) indicates both clusters are active,
* and cluster preemption is disabled (so APs remain distributed instead of failing back to the primary cluster).
Why the Other Options Are Incorrect:
* A. Cluster homogeneity/heterogeneity does not influence AP distribution behavior.
* B. If preemption were enabled, APs on the secondary cluster would fail back to the primary, not stay split.
* D. The number of nodes does not determine AP load balancing or distribution.
# Final Verified answer: C. The primary and secondary gateway clusters are up, but the cluster preemption is not enabled.

NEW QUESTION # 21
A network administrator wants to configure an 802 1X supplicant for a wireless network that includes the following:
1. AES encryption
2. EAP-MSCHAPv2-based user and machine authentication
3. validation of server certificate in Microsoft Windows 10
The network administrator creates a WLAN profile and selects the change connection settings option Then the network administrator changes the security type to Microsoft Protected EAP (PEAP) and enables user and machine authentication under Additional Settings.
What must the network administrator do next to accomplish the task?
- A. Enable user authentication
- B. Change default RC4 encryption for AES
- C. Enable server certificate validation
- D. Change the security type to Microsoft: Smart Card or other certificate.
Answer: C
Explanation:
When configuring an 802.1X supplicant for wireless network access with Microsoft Windows 10, enabling server certificate validation is a critical step to ensure the security of the authentication process. Server certificate validation helps prevent man-in-the-middle attacks by ensuring the RADIUS server presenting the certificate is the correct server that the client expects to communicate with.
NEW QUESTION # 22 
A university runs its own TV station in the city. The IT department deploys a multimedia server so the TV productions can be sent out to the entire campus over the IP network using multicast-based communications.
In order to improve the bandwidth consumption, PIM Sparse Mode and IGMP Snooping features are enabled.
When wireless users join the multicast groups, all users connected to the same WLAN experience poor network performance. However, wired users are not affected in this way. While troubleshooting, the network administrator saves the packet captures shown in the exhibit and concludes that all users, even those not joining the multicast group, receive the same multicast flow at slow speeds.
Which features should the network administrator enable to fix the problem?
- A. UCC QoS correction and Multicast Transmission Optimization
- B. Dynamic Multicast Optimization and Multicast Transmission Optimization
- C. ARP broadcast conversion into unicast and Multicast Transmission Optimization
- D. Dynamic Multicast Optimization and UCC QoS correction
Answer: B
Explanation:
* In WLANs, multicast frames are transmitted at the lowest basic rate, so a single multicast stream can consume significant airtime and slow the entire BSS, impacting clients that did not even join the group.
* Dynamic Multicast Optimization (DMO) converts multicast streams to per-client unicast, allowing the AP to use the highest supported unicast data rate and reliable retransmission-this prevents the low-rate multicast airtime penalty.
* Multicast Transmission Optimization (MTO) raises the transmit rate for any remaining multicast
/broadcast that must still be sent as multicast, further reducing airtime.
* The captures show multicast sent as 802.11 data at a low rate; enabling DMO + MTO addresses exactly this symptom in Aruba deployments.
References: Aruba WLAN Optimization and QoS guides-sections on DMO (multicast-to-unicast conversion at highest rate) and MTO (increase multicast/broadcast TX rate).
NEW QUESTION # 23
An existing AOS-10 wireless deployment is expanding its zero-trust wireless network to multiple locations.
The requirement is to propagate role information to enforce group-based policies for wireless client traffic across all locations.
To achieve this goal, which must be configured in this infrastructure?
- A. Configure "use switch fabric for role propagation" under Security # Client Roles in HPE Aruba Networking Central
- B. Tunneled SSIDs with gateways
- C. Overlay campus switch fabric with CX switches
- D. Configure the gateways to mobility type and configure the Roles under System # Client Roles in HPE Aruba Networking Central
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract of HPE Aruba Networking Switching:
In AOS-10 deployments using Zero Trust network architecture, user and device identities are enforced through roles assigned by ClearPass or Aruba Central policies. For multi-site environments, maintaining consistent policy enforcement requires role propagation between gateways across different locations.
To propagate user roles and policies across sites, tunneled SSIDs with gateways are required. This design ensures that wireless client traffic is tunneled from the access point (AP) to the Aruba gateway, where role- based access control (RBAC) and policy enforcement occur. The gateway acts as the policy enforcement point (PEP) for both local and remote traffic.
Exact Extract from HPE Aruba Networking AOS-10 and Switching Documentation:
"In AOS 10, tunneled SSIDs are used to extend centralized policy enforcement to gateways. Gateways apply user roles, firewall policies, and dynamic segmentation consistently across distributed sites."
"For zero-trust designs requiring cross-site role propagation, all wireless traffic must terminate on gateways through tunneled SSIDs. Gateways then synchronize role information through the overlay tunnel or mobility framework." Thus, the only way to propagate role information between multiple sites in a zero-trust deployment is through tunneled SSIDs that terminate at the Aruba gateways. This ensures consistent policy enforcement across locations.
Why the Other Options Are Incorrect:
* A. Configure the gateways to mobility type and configure the Roles under System # Client Roles in Central:While mobility type configuration is used for roaming, it does not enable role propagation across sites. Roles must be tied to tunneled SSIDs terminating on gateways for centralized enforcement.
"Gateway mobility enables seamless roaming, not centralized role propagation."
* B. Configure "use switch fabric for role propagation" under Security # Client Roles:This option applies to AOS-CX switch fabrics (Campus Fabric design) and not wireless AOS-10 environments.
Wireless role propagation uses gateway tunnels, not switch fabric propagation.
"Use switch fabric for role propagation applies to CX switch-based VXLAN fabrics, not wireless gateway deployments."
* C. Overlay campus switch fabric with CX switches:While Aruba CX fabrics can propagate roles in wired environments, this does not fulfill the requirement for wireless role propagation between remote sites.
"Role propagation over CX fabric applies to wired clients and does not substitute for tunneled SSID gateways in wireless networks." References of HPE Aruba Networking Switching Documents or Study Guide:
* Aruba AOS 10 Network Design Guide - "Zero-Trust Design and Role Propagation in Multi-Site Deployments."
* Aruba Campus Wireless and Gateway Deployment Guide - "Tunneled SSIDs and Centralized Role Enforcement."

NEW QUESTION # 24
A campus topology uses VSXwith a collapsed core topology.The customer added redundant SFP+ transceivers and reconfigured their mobility gateways from a single link to an aggregate Link.You are asked to verify the CLI output for the link aggregation configuration for one of the mobility gateway cluster members below.
What is a valid configuration?
- A.
- B.
- C.
- D.
Answer: C
Explanation:
The configuration shown in Option A is a valid configuration for a multi-chassis link aggregation (MC-LAG) setup. It specifies the use of LACP (Link Aggregation Control Protocol) with a fast rate of LACP PDUs exchange, which is appropriate for creating a resilient and high-throughput link aggregation. The 'vlan trunk allowed all' command allows all VLANs across the trunk, and 'vlan trunk native 100' sets VLAN 100 as the native VLAN for untagged traffic.
NEW QUESTION # 25
A customer is planning to add loT devices that connect wirelessly to the existing 802.1X SSlD. The customer will use ClearPass to authenticate the IoT devices by MAC address but other devices will still need to authenticate by only 802 1X Exhibit.
The customer provided the current configuration and reported their non-loT 802. IX devices are no longer able to connect. Which configuration change can be made to fix the issue?
- A. Modify max-authentication failures to 0.
- B. Remove mac-authentication from the WLAN configuration
- C. Modify opmode wpa3-aes-gcm-256 to opmode wpa2-aes
- D. Add i2-autn-fairtnrougn to the WLAN configuration
Answer: B
Explanation:
The existing configuration for the WLAN ssid-profile has enabled MAC authentication which, while suitable for IoT devices that may not support 802.1X, can interfere with the normal 802.1X authentication process for other devices. By removing themac-authenticationdirective from the WLAN configuration, the non-IoT
802.1X devices should be able to connect without issues as the authentication process will not be disrupted by MAC authentication checks. This adjustment ensures that the WLAN ssid-profile is correctly aligned with the authentication requirements for both IoT and non-IoT devices within the network environment, conforming to the best practices for mixed-device WLAN configurations.
NEW QUESTION # 26
Your customer's employees connected to a wired network are complaining about a poor user experience. The customer has UXI sensors deployed on their premises. These sensors nave been running for multiple months.
They are testing both the wired network (using the wired Interface of each sensor) and the wireless networks.
Your customer used the UXI dashboard to find the reason for the poor userexperience to find more details, the customer asked you to check the packet captures that have been downloaded from the sensors using the UXI dashboard.
From the zip file downloaded from the UXI sensors, you checked the "datagrams" .pcap file, but you were not able to find any issues How can you explain this?
- A. The default filers of the packet captures do not allow tailed tests to be captured by the sensor
- B. The UXI sensor could not upload the latest test results to the cloud, so the packet capture is outdated
- C. The datagrams captured on the physical Ethernet interface are in a different .pcap file.
- D. The "datagrams- pcap file only contains me successful tests Failed tests are contained in the
"datagrams-failed" .pcap file
Answer: D
Explanation:
It is a common practice to separate successful and failed test results into different files for ease of troubleshooting. If the "datagrams.pcap" file shows no issues, it's likely because it only contains successful test data, and the failed tests that could explain the poor user experience would be in a different file, such as
"datagrams-failed.pcap."
NEW QUESTION # 27
What is the recommended configuration to ensure link aggregation is consistent in a campus topology using VSX with two aggregation switches and downlinks to access switches?
- A. Use the command "vsx-sync active-gateways" under the VSX context.
- B. Use a custom LACP hash algorithm for improved load balancing.
- C. Use the command "vsx-sync mclag-interfaces" under the VSX context.
- D. Use the command "vsx-sync mclag-interfaces" from the global context.
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Exact Extract of HPE Aruba Networking Switching:
The VSX synchronization feature provides per-feature synchronization from the primary to the secondary VSX peer. For multi-chassis LAGs (MC-LAGs), the command that ensures both VSX peers maintain consistent LAG interface associations and attributes is entered under the VSX configuration context:
* Command syntax: vsx-sync mclag-interfaces
* Command context: config-vsx
Description (extract): Enables VSX synchronization of VSX LAG interface associations and attributes from the primary VSX switch to the secondary peer switch.
In a campus design with two aggregation switches in a VSX pair and access switches dual-homed using MC- LAG, enabling vsx-sync mclag-interfaces under the VSX context ensures consistent LAG membership, attributes, and behavior across the pair-avoiding configuration drift and aggregation inconsistencies.

NEW QUESTION # 29
A customer is evaluating device profiles on a CX 6300 switch. The test device has the following attributes:
* MAC address = 81:cd:93:13:ab:31
* LLDP sys-desc = iotcontroller
The test device is being assigned to the ''lot-dev'' role However, the customer requires the "lot-prod'' role be applied.
Given the configuration, what is causing the "iot-dev" role to be applied to the device'?
- A. An external RADIUS server is unreachable.
- B. The test device does not support CDP.
- C. The LLDP system description matches the IIdp-group configuration.
- D. The device-profile precedence order is not configured.
Answer: C
Explanation:
In device profile configuration, the device role is often determined by matching attributes such as MAC address, LLDP system description, and CDP information against defined conditions. The test device is being assigned the "iot-dev" role because its LLDP system description matches the 'iot-lldp' group configuration that is associated with the 'iot-dev' role.

Which command would allow you to verity receipt of a CoA message on an AOS 10 GW?
- A. packet-capture controipath udp 3799
- B. packet-capture datapath udp 3799
- C. packet-capture interprocess udp 3799
- D. tcpdump host-port 3799
Answer: A
Explanation:
The Change of Authorization (CoA) messages are used in network access control scenarios and are typically received by the network access server, in this case, an Aruba AOS 10 Gateway. The correct command to verify the receipt of a CoA message is related to the control path traffic because CoA is a control plane function.
Option B,packet-capture controlpath udp 3799, is the correct answer because it specifies capturing control plane traffic on UDP port 3799, which is the standard port for CoA messages.
Options A, C, and D are incorrect because:
Option A captures data plane traffic, not control plane traffic.
Option C'spacket-capture interprocess udp 3799does not refer to a standard command for capturing CoA messages.
Option D,tcpdump host-port 3799, does not specify the correct syntax for capturing traffic on Aruba devices.

An engineer has applied the above configuration to R1 and R2. However, the router's OSPF adjacency never progresses past the "EXSTART/DR" state.
Which configuration action on either router will allow R1 and R2 to progress past the "EXSTART/DR" state?
- A. Remove the layer 3 MTU configuration
- B. Change R1 and R2 to a network type of point-to-point
- C. Change the IP address and mask applied to interface 1/1/1
- D. Ensure the OSPF process is not configured with passive-interface default
Answer: A
Explanation:
In Aruba AOS-CX, OSPF neighbors that reach EXSTART/EXCHANGE but fail to advance typically indicate a database description (DD) negotiation issue, most commonly caused by an MTU mismatch on the link. The OSPF header carries the interface MTU; if the values do not match, the peer rejects DD packets and the adjacency remains stuck at EXSTART (often shown as EXSTART/DR or EXSTART/BDR).
Aruba's OSPF guidance states:
* "If neighbors remain in EXSTART/EXCHANGE, verify that the Layer-3 MTU matches on both ends of the adjacency. An MTU mismatch causes DD packets to be rejected and prevents the adjacency from reaching FULL."
* Recommended corrective action is to align or remove custom L3 MTU settings on the participating interfaces (or use the mtu-ignore feature where appropriate).
In this scenario, removing the custom Layer-3 MTU configuration so both sides use the same default MTU allows DD packet negotiation to succeed and the adjacency to progress to FULL.
