NEW QUESTION # 21
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. lot-local
- B. client will be rejected network access
- C. byod
- D. unmatched-device
Answer: D
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 # 22
You configured a tunneled SSID with captive portal and a ClearPass Guest Self Registration workflow when testing and launching the self-registration workflow, after successful registration, the login action shows the following error:
What is the best solution to resolve this error?
- A. You need to include the root and intermediate certificates in the captive portal certificate for your gateway
- B. You need to include the root and intermediate certificates in the captive portal certificate for your access points
- C. You need to De connected to the guest SSiD while testing.
- D. You need to change the Login Address in ClearPass to securelogin arubanetworKs.com
Answer: A
Explanation:
Including the root and intermediate certificates in the captive portal certificate for the gateway will resolve the error seen during the login action after successful registration. This is necessary to ensure the SSL/TLS handshake can be completed successfully, as the client browser needs to validate the entire certificate chain.

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 # 25
An ACME company employee complained about a recent poor-quality VoIP call while moving aroundtheir office environment HPE Aruba Networking Central reported a fair UCC score for this callwhile your VoIP engineer reported that their systems reported a MOS of 2,3. The VoIP devices are operatingover the 5GHz frequency band.
What are the possible contributing factors? (Select two.)
- A. 802.tr is enabled in the WLAN Security settings.
- B. There was localized interference at the caller's location
- C. Coverage AP deployment plans generally don't support enough cell overlap for VoIP.
- D. 802.1K is disabled in the WLAN Security settings
- E. The client roamed into an area that continuously operates Zigbee.
Answer: C,E
Explanation:
VoIP quality can be negatively impacted by insufficient cell overlap in AP deployment plans, which can cause poor handoffs between APs as a user moves around. This results in a degraded VoIP experience. Additionally, roaming into an area with continuous Zigbee operation can cause interference with the 5GHz frequency band, further contributing to poor VoIP call quality. The Zigbee communication protocol operates on the same frequency band as Wi-Fi and can introduce noise and interference, which leads to a reduced MOS score, as reported by the VoIP engineer.
NEW QUESTION # 26
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: C
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.

Anetworkadministrator accesses HPE Aruba Networking Central and notices that visitors consume too much internet bandwidth starving employee traffic when accessing an external service.Therefore,the administrator wants to limitwireless bandwidth to 60 Mops in both directions among all users in the voice rote and no more than 10 Mops in both directions for YouTube traffic. Deep packet inspection, web contentclassification, andfirewall visibility are enabled.
Which configurations are required to accomplish this task? (Select two.)
- A.
- B.
- C.
- D.
Answer: A,B
Explanation:
To achieve the bandwidth limits set by the network administrator, both per-application and total limits need to be configured. Option B shows the configuration for setting a per-application bandwidth limit, which can restrict YouTube traffic to 10 Mbps in both directions. Option D shows the configuration for setting a total bandwidth limit for all users within the voice role to 50000 Kbps (or 50 Mbps), satisfying the requirement to restrict total wireless bandwidth. By applying these configurations in HPE Aruba Networking Central, the administrator will successfully implement the necessary controls to ensure that visitor traffic does not impede the network performance for employee traffic, aligning with the capabilities of Aruba solutions to manage and prioritize network resources effectively.
NEW QUESTION # 30
Exhibit.
Which user role will be assigned when a voice client tries to connect for the first time, but the RADIUS server is unavailable?
- A. CRITICAl_AUTH
- B. DEFAULT_AUTH
- C. CRIT1CAL_V0ICE
- D. PRE_AUTH
Answer: C
Explanation:
In the provided configuration for interface 1/1/7, there are roles specified for different scenarios concerning authentication. When a voice client attempts to connect and the RADIUS server is unreachable, the role that is assigned is the one specified as the "critical-voice-role". In this case, the "CRITICAL_VOICE" role is configured to be assigned under such circumstances, ensuring that voice clients receive appropriate network access permissions even when the RADIUS server is not available to authenticate them.
NEW QUESTION # 31
Which option shows the correct Banawidth Control for 1024 kbpsdown and 2048 Kops up for the SSID?
- A.
- B.
- C.
- D.
Answer: D
Explanation:
The correct Bandwidth Control settings for 1024 Kbps down and 2048 Kbps up for the SSID are shown in Option D. In Option D, the downstream is set at 1024 Kbps and the upstream at 2048 Kbps, both configured per user, which matches the requested configuration. This setup ensures that each user has a guaranteed bandwidth allocation of the specified rates when connected to the SSID, providing a controlled and predictable user experience.
NEW QUESTION # 32

- A. The SSID supports HR-DSSS data rates
- B. The SSID supports 802 11ax clients.
- C. The SSID is supports 6 GHz clients.
- D. The SSID supports 802 11ac clients.
Answer: B
Explanation:
The exhibit shows that the SSID supports 802.11ax clients, which is indicated by the presence of HT (High Throughput) information, VHT (Very High Throughput) capabilities, and HE (High-Efficiency) operation, which are all features associated with 802.11ax, also known as Wi-Fi 6.
NEW QUESTION # 33
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. The WPA3 Enterprise GCM-2S6 mode does not support transition mode.
- C. MAC authentication after a failed 802. ix authentication is not possible as the option "MAC Authentication Fall-Through" is disabled.
- D. WPA3 Enterprise is not backward compatible with WPA2 Enterprise.
Answer: C
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 # 34
After onboarding three new AOS 10 gateways using the full-setup methodinto the same Central group, a customer cannot log in to one of the gateways using the HPE Aruba Networking Central remote console due to an incorrect password.
- A. The admin password created at the Central group level has expired
- B. The admin password created during the full-setup process does not match the Central group admin password
- C. The admin password created using full-setup does not match the global Central admin password.
- D. The admin password created during the run-setup process is not configured to allow me remote console access
Answer: B
Explanation:
When onboarding devices into a centralized management system, each device can have its individual admin password set during the onboarding process. If this password doesn't match what is expected at the group level in the central management platform, login issues such as the one described can occur.
NEW QUESTION # 35
Exhibit.
A network administrator attempts to improve multicast traffic flow and performs some packet captures for validation What can the network administrator conclude from the results?
- A. The data rate increased from 6 Mbps to 300 Mops because Dynamic Multicast Optimization (DMO) was configured.
- B. The type flew remains consistent because Dynamic Multicast Optimization (DMO) was configured.
- C. The capture taken after optimization does not show a packet length because Multicast Transmission Optimization was configured.
- D. The data rate increased from 6 Mops to 300 Mops because Broadcast Multicast optimization (BCMCO) was configured.
Answer: A
Explanation:
Dynamic Multicast Optimization (DMO) is a feature that enhances the delivery of multicast traffic by optimizing the data rate. The before and after optimization images show a significant increase in the data rate, which is a typical result of DMO being configured, as it allows multicast traffic to be transmitted at higher data rates by converting multicast streams into unicast streams for the clients that need them.
NEW QUESTION # 36
The ACME company has an AOS-CX 6200 switch stack with an uplink oversubscription ratio of 9.6:1. They are considering adding two more nodes to the stack without adding any additional uplinks due to cabling constraints One oftheir architects has expressed concerns that their critical UDP traffic from both wired and bridged AP clients will encounter packet drops.They have already applied the following configuration:
Which strategy will complement this solution to achieve their objective?
- A. edge mark lower priority TCP traffic with AF11
- B. edge mark critical UDP traffic with AF42
- C. edge mark critical UDP Traffic with CSS
- D. edge mark lower priority TCP traffic with AF12
Answer: B
Explanation:
Given that the ACME company's concern is about UDP traffic potentially encountering packet drops due to uplink oversubscription, they need a strategy that prioritizes critical UDP traffic to minimize loss.
Option D,edge mark critical UDP traffic with AF42, is the correct answer. Assured Forwarding (AF) classes provide a way to assign different levels of delivery assurance for IP packets. AF42 is typically used for traffic that requires low latency and low loss, such as voice and video, which often use UDP. Marking critical UDP traffic with AF42 will help ensure that this traffic is treated with higher priority over the network.
Option A (edge mark lower priority TCP traffic with AF12) and Option C (edge mark lower priority TCP traffic with AF11) suggest marking lower priority TCP traffic, which does not directly address the concern for critical UDP traffic.
Option B (edge mark critical UDP Traffic with CS5) suggests using Class Selector 5 for critical UDP traffic, which is also a valid approach but does not match the existing configuration that is focused on Assured Forwarding (AF) classes.
NEW QUESTION # 37
A customer is running out of IP addresses in a network segment. What will happen If they add an additional IPsubnet to the same VLAN?
- A. Users can reach each other and establish PTP traffic without passing an L3 point in the same VLAN
- B. Broadcasts for me two subnets win arrive on all ports in the same VLAN
- C. This would result in a single SVI using two subinterfaces.
- D. IGMP will not work in both of the subnets in the same VLAN
Answer: A
Explanation:
Adding an additional IP subnet to the same VLAN means that devices configured with either subnet can communicate at Layer 2 without the need for routing. This is because they are on the same VLAN and thus in the same broadcast domain. However, to communicate between subnets, an L3 device or inter-VLAN routing would be required.
NEW QUESTION # 38
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 datagrams captured on the physical Ethernet interface are in a different .pcap file.
- B. The UXI sensor could not upload the latest test results to the cloud, so the packet capture is outdated
- C. The default filers of the packet captures do not allow tailed tests to be captured by the sensor
- 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 # 39
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. The RadSec server was defined on the switch using an IPv6 address that was unreachable
- B. Tracking mode was set to "dead-only", and the RadSec server was marked as unreachable.
- C. The switch is configured to establish a TLS connection with a proxy server, not the radius server.
- D. The RADIUS TCP packets are Being dropped and the TLS tunnel is not established.
Answer: D
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 # 40
Exhibit.
A customer is reporting mat connectivity is Tailing for some wireless client Devices. What are your conclusions from the capture? (Select two.)
- A. The client is not receiving an IP address.
- B. The client does not have an ARP entry for me default gateway.
- C. The client does not support beamforming.
- D. The network is using WPA2-PSK key management.
- E. The network is using WPA3-SAE key management.
Answer: A,D
Explanation:
The capture shows messages related to WPA key management, indicating WPA2-PSK is being used. Also, the capture includes a DHCP request from the client but no corresponding DHCP ACK, suggesting the client is not receiving an IP address, which could explain the connectivity failure.
