NEW QUESTION # 11
You created a new SSID with the security settings shown in the exhibit.
Some, but not all users complain that client devices are unable to connect to this SS1D. What is the reason for this?
- A. The primary servers shared key differs from the shared key configured for this server on HPE Aruba Networking Central.
- B. MAC authentication after a failed 802. ix authentication is not possible as the option "MAC Authentication Fall-Through" is disabled.
- C. The WPA3 Enterprise GCM-2S6 mode does not support transition mode.
- D. WPA3 Enterprise is not backward compatible with WPA2 Enterprise.
Answer: B
Explanation:
If some users are unable to connect to an SSID configured with WPA3-Enterprise GCM-256, and the "MAC Authentication Fall-Through" is disabled, it means that devices which fail 802.1X authentication will not attempt MAC authentication. If these client devices are configured to use MAC authentication as a backup method, they will fail to connect, explaining the issue faced by some users.

NEW QUESTION # 13
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. The LLDP system description matches the IIdp-group configuration.
- B. The device-profile precedence order is not configured.
- C. An external RADIUS server is unreachable.
- D. The test device does not support CDP.
Answer: A
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.
NEW QUESTION # 14
Which statement is true given the following CLIoutput from a CX 6300?
- A. There are three active client overlay VLANs in the overlay fabric
- B. Duplicate MAC addresses were detected in the overlay fabric
- C. There are two anycast addresses m me overlay fabric.
- D. The underlay loopback addresses are in the 172 21 11 x range.
Answer: D
Explanation:
The CLI output displays EVPN routes and their corresponding next hops. The "Route Distinguisher" entries followed by IP addresses in the 172.21.11.x range indicate these are loopback addresses used by the underlay network. The underlay network provides the basic routing and forwarding plane for the overlay network that EVPN is part of. These loopback addresses are crucial for the proper functioning of the EVPN control plane.
NEW QUESTION # 15
A deployment using AP-635S is connectedto a stack of CX 6300s as shown.
The output of the snow LACPinterfaces shews the following:
What is causing this issue?
- A. Spanning tree and loop protect are enabled on both AP uplink ports.
- B. e0 is connected to a smart rate interface, and e1 is connected to a non-smart rate interface.
- C. The AP is configured with LACP active
- D. Each AP interface is connected to a routed-only interlace on different networks
Answer: C
Explanation:
In an Aruba deployment, if an AP's interfaces show different LACP states, it often indicates a configuration mismatch. If one interface is up and the other is blocked as shown in the output,it's likely due to both interfaces on the AP being set to LACP active mode, which is a correct setting for establishing an LACP channel with Aruba switches like the CX 6300 series.

Exhibit.
Which wireless connection phase has Just been completed?
- A. L3 authentication and encryption
- B. L2 authentication and encryption
- C. 802.11 enhanced open association
- D. MAC Authentication and 4-way handshake
Answer: B
Explanation:
The wireless connection phase that has just been completed is L2 authentication and encryption. This phase includes processes such as the Extensible Authentication Protocol (EAP) exchange, RADIUS requests and responses, and the 4-way handshake which is characteristic of WPA2-AES encryption.
NEW QUESTION # 17
A customer wan a gateway connected to a device on gigabitethernet0/0/3 configures an Asset ID TLVon the device for inventory management.
Exhibit.
The customer mentions me Asset ID is not shown What is causing the issue?
- A. Unknown TLVs cannot be displayed.
- B. LLDP TX is not enabled.
- C. MTU size is too small.
- D. LLPD-MED needs to be enabled.
Answer: A
Explanation:
The issue is that unknown TLVs (Type Length Values) cannot be displayed. LLDP (Link Layer Discovery Protocol) is used to share device information with network neighbors, but if a TLV is not recognized by the LLDP implementation on the gateway, it won't be displayed or processed. Hence, the Asset ID TLV set on the device for inventory management is not showing up because it is unrecognized or unsupported by the gateway's LLDP.
NEW QUESTION # 18
You are deploying a new AOS 10 mobility gateway cluster. Due to customer requirements, the gateways must be configured with static IP addresses and are restricted from communicating using port 443 to any URLs except tor "central arubanetworks.com How would you onboard these gateways successfully into HPE Aruba Networking Central?
- A.
- B.
- C.
- D.
Answer: D
Explanation:
Option A includes all necessary steps for a full setup of an AOS 10 mobility gateway cluster, including setting the system name, switch role, ACP FQDN address, uplink port information, IP address and default gateway, DNS IP address, controller country code, timezone and clock, andadmin password. Since the gateways must have static IP addresses and can only communicate on port 443 for a specific URL, this configuration would need to allow for static IP configuration and restrict communication to the required URL.

The wireless administrator for a college campus is gelling reports of connectivity issues when students are working outdoors.
Reviewing the settings above, watch change is needed to align with best practices?
- A. increase 5Gnz TX power range Min/Max.
- B. Disable 802 11r.
- C. increase 5 GHz wireless coverage tuning to Aggressive.
- D. Disable 802 11k.
Answer: A
Explanation:
To address connectivity issues when students are working outdoors, increasing the transmission (TX) power range for the 5GHz radios can help improve signal strength and coverage. The setting shown indicates a conservative approach to power settings, which might not provide sufficient coverage for outdoor areas. By increasing the power range, you can extend the wireless signal reach, which aligns with best practices for outdoor wireless coverage.
NEW QUESTION # 21
You recently added ClearPass as an authentication server to an HPE Aruba Networking Central group.
RADIUS authentication with Local User Roles (LUR) works fine Out the same access points cannot use Downloadable User Roles (DUR).
What should he corrected in this configuration to fa the issue with DUR?
- A. Replace the AP's expiree digital certificate using the "crypto pki-import pem serverCert" command.
- B. Add the correct IP addresses or IP subnets of the Network Access Devices(NADs) under the "Devices" tabon ClearPass
- C. Add the correct values for "CPPM username" and "CPPM Password" m the authentication server configuration on HPEAruba Networking Central
- D. Add a new Enforcement Policy of type ''WEBAUTH''on ClearPass and associate it with the matching service on ClearPass
Answer: B
Explanation:
For Downloadable User Roles (DUR) to function correctly with ClearPass, the Network Access Devices (NADs) need to be correctly defined in ClearPass under the "Devices" tab. This ensures that ClearPass can identify and communicate with the NADs to deliver the appropriate user roles. If the NADs are not correctly defined, ClearPass will not be able to provide the DURs to the access points for enforcement. This is a common configuration step that is required to integrate ClearPass with network devices for advanced role-based access control.
NEW QUESTION # 22
in a WLAN network with a tunneled SSID. you see the following events in HPE Aruba Networking Central:
The customer asks you to investigate log messages What should you tell them?
- A. This indicates a client WLAN driver issue for the client with a MAC address ending with 37:18
:Od. You should upgrade the client WLAN driver. - B. This is normal, expected behavior. No further actions are needed.
- C. This indicates a security issue. The client with a MAC address ending with 37 18;0d Is performing a Denial-of-Service attack on your network. You should track down the client and remove it from the network.
- D. There is a roaming issue Enable Fast Roaming 802.11r and OKC to resolve the issue.
Answer: B
Explanation:
The event log showing PMK (Pairwise Master Key) and OKC (Opportunistic Key Caching) key add/update and delete operations is indicative of normal client behavior in a WLAN environment. These events are part of the standard process for maintaining client session security and do not necessarily indicate any issue.
NEW QUESTION # 23
Which command would allow you to verity receipt of a CoA message on an AOS 10 GW?
- A. tcpdump host-port 3799
- B. packet-capture datapath udp 3799
- C. packet-capture interprocess udp 3799
- D. packet-capture controipath udp 3799
Answer: D
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.
NEW QUESTION # 24
You configured a WPA3-SAE with the following MAC Authentication Role Mapping inCloud Authentication and Policy:
With further default settings assume a new Android phone is connected to the network. Which role will the client be assigned after connecting forthe first time?
- A. unmatched-device
- B. byod
- C. client will be rejected network access
- D. lot-local
Answer: A
Explanation:
The configuration shown in the third exhibit details a client role mapping that associates different client profile tags with specific client roles. When a new device, such as an Android phone, connects to the network, it will be profiled and assigned a role based on the mappings defined. If the device does not match any predefined profiles, it would be assigned the "unmatched-device" role. This is under the assumption that default settings are in place and the client does not match the criteria for any of the specific roles like "byod", "iot-internet", or
"iot-local". Therefore, an Android phone connecting for the first time and not matching any specific profile tag would be assigned to the "unmatched-device" role.
NEW QUESTION # 25
A customer has deployed an AOS 10 mobility gateway cluster consisting of three controllers at a single site The WLAN is configured to tunnel wireless device traffic to the AOS 10 mobility cluster The clients are authenticated by ClearPass using WPA3-Enterprise (opmode wpa3-aes-ccm-128). The security team has requested the ability to force a wireless device to reauthenticate using ClearPass.
Which steps are required to ensure ClearPass can consistently initiate a change of authorization against an AOS 10 mobility cluster, including during gateway failover scenarios? (Select two)
- A. modify NAS IPv4 address under Security - Advanced - RADIUS Client
- B. enable Dynamic Authorization CoA under High Availability - Cluster Configuration
- C. modify WLAN - SSID - VLAN - Mode Configuration
- D. set cluster mode to Auto Site under High Availability - Cluster configuration
- E. enable manual cluster configuration under High Availability - Cluster Configuration
Answer: A,B
Explanation:
To ensure that ClearPass can initiate a Change of Authorization (CoA) consistently, it's important to enable dynamic authorization to allow RADIUS CoA messages to be processed. This setting typically falls under the high-availability cluster configuration to ensure that it persists across gateway failovers. Additionally, the NAS IP address must be configured under RADIUS client settings to ensure that the correct IP address is used for RADIUS communications, which is necessary for CoA to function correctly.
NEW QUESTION # 26
A network technician racked up two 9240 mobility gateways in a single cluster that will be terminating 1700 APs in a medium-sized branch office Next, the technician cabled the gateways with two SFP28 Direct Attach Copper (DAC) cables, distributed between a two-member core switching stack and powered them up.
What must the network administrator do next regarding the gateway configuration to ensure maximum wired bandwidth utilization?
- A. Make an ports trunk interfaces and permit data VLANs
- B. Manually set 25Gbps speeds on all ports.
- C. Disable the spanning tree and allocate unique VLANs to each port.
- D. Map two physical ports to a port channel on each gateway.
Answer: D
Explanation:
To maximize wired bandwidth utilization, especially when multiple APs are terminating on mobility gateways, it's best practice to aggregate physical ports into a port channel. This provides redundancy and increased bandwidth by combining the throughput of multiple ports.
NEW QUESTION # 27
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 datagrams captured on the physical Ethernet interface are in a different .pcap file.
- C. The UXI sensor could not upload the latest test results to the cloud, so the packet capture is outdated
- 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 # 28
You are testing the use of the automated port-access role configuration process using RadSec authentication over VXLAN. During your testing you observed that the RadSec connection will fan during the digital certificate exchange What would be the cause of this Issue?
- A. Tracking mode was set to "dead-only", and the RadSec server was marked as unreachable.
- B. The RADIUS TCP packets are Being dropped and the TLS tunnel is not established.
- C. The switch is configured to establish a TLS connection with a proxy server, not the radius server.
- D. The RadSec server was defined on the switch using an IPv6 address that was unreachable
Answer: B
Explanation:
During the testing of RadSec authentication over VXLAN, if the RadSec connection fails during the digital certificate exchange, it typically indicates an issue with the establishment of the TLS tunnel, which is required for RadSec's secure communication. The failure of TLS tunnel establishment can occur due to RADIUS TCP packets being dropped, preventing the secure exchange of digital certificates necessary for RadSec authentication. The other options, such as IPv6 address reachability, tracking mode settings, and proxy server misconfiguration, are not directly related to the failure of the TLS tunnel establishment during the certificate exchange process
NEW QUESTION # 29
A customer's infrastructure is set up to use Doth primary and secondary gateway clusters on the SSID profile What is a valid reason for the AP to failover to the secondary gateway cluster?
- A. The primary gateway cluster is up. out the AP is unable to reach the primary gateway cluster.
- B. The secondary gateway cluster is homogeneous.
- C. The secondary gateway cluster is heterogeneous.
- D. The secondary gateway cluster is up. hut the AP is unable to reach the secondary gateway cluster
Answer: A
Explanation:
In Aruba's infrastructure, the Access Points (APs) are configured with primary and secondary gateway clusters to ensure connectivity and resiliency. The APs will failover to the secondary gateway cluster if they are unable to reach the primary gateway cluster, even if the primary cluster is operational. This mechanism ensures that the APs maintain connectivity to the network infrastructure for continuous service delivery.
