NEW QUESTION # 16
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 opmode wpa3-aes-gcm-256 to opmode wpa2-aes
- B. Add i2-autn-fairtnrougn to the WLAN configuration
- C. Modify max-authentication failures to 0.
- D. Remove mac-authentication from the WLAN configuration
Answer: D
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 # 20
Exhibit.
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. PlM 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. Dynamic Multicast Optimization and Multicast Transmission Optimization
- B. UCC QoS correction and Multicast Transmission Optimization
- C. Dynamic Multicast Optimization and UCC QoS correction
- D. ARP broadcast conversion into unicast and Multicast Transmission Optimization
Answer: A
Explanation:
Dynamic Multicast Optimization (DMO) and Multicast Transmission Optimization are features that can help address issues with multicast traffic in wireless environments. DMO optimizes the way multicast traffic is transmitted over the air by converting multicast streams into unicast streams to the clients that need them. This reduces unnecessary traffic for clients that have not subscribed to the multicast group and can improve overall network performance. Multicast Transmission Optimization adjusts the transmission rate of multicast frames to ensure they are sent at optimal speeds, addressing the issue of multicast flow being received at slow speeds by all users.

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.
NEW QUESTION # 23
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. 802.1K is disabled in the WLAN Security settings
- D. The client roamed into an area that continuously operates Zigbee.
- E. Coverage AP deployment plans generally don't support enough cell overlap for VoIP.
Answer: D,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 # 24
Refer to the exhibit.
Which statement is true?
- A. The client is using BSS Fast Transition
- B. The client used an incorrect passphrase
- C. The client performed passive scanning
- D. The client is failing 802.1X authentication
Answer: D
Explanation:
The exhibit shows a series of 802.1X authentication steps with multiple "Deauthentication" frames, which indicate that the client is not successfully completing the authentication process. Since the frames show repeated attempts at authentication followed by deauthentication, this suggests that the client is failing the
802.1X authentication process, which is required for network access in a WPA2/WPA3-Enterprise security environment.
NEW QUESTION # 25
Based on best practices if an SSID is configured Tor a primary and secondary gateway cluster with cluster preemption enabled, which will decide if the APs move to the secondary gateway cluster if all of the nodes in the primary gateway cluster are down?
- A. every AP individually
- B. cluster leader in the secondary gateway cluster
- C. cluster leader in the primary gateway cluster
- D. tunnel orchestrator for LAN tunnel service in HPE Aruba Networking Central
Answer: A
Explanation:
In an Aruba network, if an SSID is configured for a primary and secondary gateway cluster with cluster preemption enabled, each AP individually will decide to move to the secondary gateway cluster if all of the nodes in the primary gateway cluster are down. This decentralized decision-making process enhances network resilience and ensures uninterrupted service for clients connected to the APs.
NEW QUESTION # 26
An administrator is creating a fabric withNetConductor in HPE Aruba Networking Central Considering an EVPN VXLAN fabric, click on the most appropriate layer to be configured as a Rome-Reflector Persona.
Answer:
Explanation:
Explanation:
In the context of an EVPN VXLAN fabric, the Route-Reflector Persona is most appropriately configured at theServices Aggregationlayer. This layer is responsible for interconnecting different network services and typically includes more robust, higher-capacity devices capable of handling the route-reflection functions for EVPN VXLAN.
In an Aruba Networks fabric, route reflectors are used to optimize the distribution of BGP routes. The Services Aggregation layer, which is centrally located in the network topology, is best suited for this role due to its high availability and ability to efficiently manage routes between the core and access layers.
Therefore, if you were to click on the image provided, you would select the Services Aggregation layer to configure the Route-Reflector Persona.
NEW QUESTION # 27
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. Move the AP-635 access points to a different group in Central to configure the dongles separately from the AP-615.
- B. Create two separate service profiles in the loT tab of the Central configuration settings.
- C. Perform a "poe disable" followed by a "poe enable" for the switch ports which connect to the APs so that the APs reboot.
- D. Replace the Class a PoE switches with Class 6 PoE switches.
Answer: D
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 # 28
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 mclag-interfaces" under the VSX context.
- B. Use the command "vsx-sync active-gateways" 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: A
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.
NEW QUESTION # 29
Exhibit.

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 # 30
Exhibit.
After configuring VRRP between sw-1 and SW-2. you notice that both switches are showing as active. What could be the reason for this issue?
- A. SW-2 has no priority configurations for VRRP 1.
- B. SW-1 cam reach SW-2 on VLAN 10.
- C. VRRP preemptive mode is disabled.
- D. Both switches are configured as VRRP 'primary.'
Answer: D
Explanation:
In VRRP (Virtual Router Redundancy Protocol), only one switch should be the primary (master) for a given virtual IP address, with the other switches being backups. If both switches are showing as active, it suggests a misconfiguration where both are set to act as the primary for the same VRRP group. The exhibits provided indicate that both switches believe they are the active or primary for the VRRP group, which is an incorrect configuration.
