You want to configure an MTU of 9198 for a routedlag interface on a CX 6300 switch.Which configuration achieves this?
- A.
- B.
- C.
- D.
Answer: B
Explanation:
In the context of ArubaOS-CX, particularly with the 6300 series switches, setting the MTU on a routed Link Aggregation Group (LAG) interface requires theinterface lag idcommand in the configuration, specifying the LAG interface you're configuring. Theip mtucommand is then used to set the desired MTU size for that LAG.
Option A correctly shows this configuration process, where the MTU is set to 9198 for the LAG interface, in line with the requirements for routing larger frames, which could be necessary for certain applications or data flows that require jumbo frames.
The information related to the configuration of Aruba switches is consistent with the principles and guidelines found in the technical documentation for the ArubaOS-CX 6300 series switches, which emphasizes the importance of correct MTU settings for network performance and stability.
NEW QUESTION # 32
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. The client roamed into an area that continuously operates Zigbee.
- B. Coverage AP deployment plans generally don't support enough cell overlap for VoIP.
- C. 802.tr is enabled in the WLAN Security settings.
- D. 802.1K is disabled in the WLAN Security settings
- E. There was localized interference at the caller's location
Answer: A,B
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 # 33
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 RadSec server was defined on the switch using an IPv6 address that was unreachable
- C. The RADIUS TCP packets are Being dropped and the TLS tunnel is not established.
- D. The switch is configured to establish a TLS connection with a proxy server, not the radius server.
Answer: C
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 # 34
A customer has interfering devices that are seen over the air. They contact you and ask you to configure RAPIDS to help identify interfering and rogue APs. HPE Aruba Networking Central identifies a rogue AP and displays the connected switch port.
How can HPE Aruba Networking Central identify which switch port the AP is connected to?
- A. from the switch MAC address table
- B. from the AP MAC address table
- C. device profiting on the switch
- D. from the switch LLDP neighbors table
Answer: A
Explanation:
HPE Aruba Networking Central can identify which switch port a rogue AP is connected to by using the switch's MAC address table. The MAC address table contains the associations between MAC addresses and the switch ports to which devices (including APs) are connected. When Aruba Central detects a rogue AP, it can look up the MAC address of the rogue AP in the switch's MAC address table to find the specific switch port it is connected to. This enables network administrators to quickly locate and address the rogue AP issue.

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 a custom LACP hash algorithm for improved load Balancing.
- 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 the command "vsx-sync mclag-interfaces" under the VSX context.
Answer: D
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 # 42
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. Perform a "poe disable" followed by a "poe enable" for the switch ports which connect to the APs so that the APs reboot.
- B. Create two separate service profiles in the loT tab of the Central configuration settings.
- C. Move the AP-635 access points to a different group in Central to configure the dongles separately from the AP-615.
- 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 # 43
Exhibit.
What is me expected behavior for ARP traffic sent from H1?
- A. A2 will send the ARP traffic out of ports 1/1/1-1/1/4.
- B. A2 will drop the ARP traffic.
- C. A2 willsend the ARP traffic out of ports 1/1/1 and 1/1/3.
- D. A2 willflood the ARP traffic out of all interfaces.
Answer: D
Explanation:
In a VXLAN environment, unknown unicast traffic, such as ARP requests from H1, which does not have a specific destination MAC address learned by the switch A2, will be flooded out of all interfaces. This flooding behavior is necessary because A2 needs to ensure that the ARP requestreaches its intended destination, which might be on any of the interfaces. It's a part of the standard behavior of switches to handle ARP traffic when the destination hardware address is unknown.
NEW QUESTION # 44
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 Mops to 300 Mops because Broadcast Multicast optimization (BCMCO) 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 Mbps to 300 Mops because Dynamic Multicast Optimization (DMO) was configured.
Answer: D
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 # 45
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. Add the correct values for "CPPM username" and "CPPM Password" m the authentication server configuration on HPEAruba Networking Central
- B. Add the correct IP addresses or IP subnets of the Network Access Devices(NADs) under the "Devices" tabon ClearPass
- C. Replace the AP's expiree digital certificate using the "crypto pki-import pem serverCert" command.
- 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 # 46
A customer is deploying a new warehouse with AP-634 APs inthe unitedStates with mobile devices that can operate in the 6GHz spectrum All testing and RF analyses were performed during the POC using AP-635 APs In a different location During the deployment, they noticed fewer 6GHz channels were broadcasting in the air.
Why would the AP-634 deployment have a lesser amount of broadcasting channels?
- A. The AP-634 AP's persona was configured in the Central group as Standard Power.
- B. The AP-634 APs cannot broadcast an 6Gnz channels due to regulatory restrictions.
- C. The AP-635 APs received different allowable 6GHz channels from the AFC service versus the AP-634 APs due to the POC running in a different location.
- D. The AP-634 APs do not have an advanced subscription.
Answer: C
Explanation:
In the United States, the operation in the 6GHz band for Wi-Fi devices such as the AP-634 and AP-635 is regulated by the Automated Frequency Coordination (AFC) system, which determines the channels that can be used based on the location. Since the Proof of Concept (POC) was conducted in a different location using AP-635 APs, the allowable channels identified by the AFC service for that location would be different than the channels allowed for the actual deployment location of the AP-634 APs. This would result in a different set of broadcasting channels being available for use in the new warehouse deployment.
NEW QUESTION # 47
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. VRRP preemptive mode is disabled.
- B. SW-2 has no priority configurations for VRRP 1.
- C. SW-1 cam reach SW-2 on VLAN 10.
- 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.
NEW QUESTION # 48
Exhibit.
Which would explain this issue?
- A. HTTPS certificate is not required in ClearPass Guest.
- B. HTTPS wildcard certificates are not supported
- C. ".aruba-training com needs to be entered in the Address field for the ClearPass Guest
- D. captiveportal-login aruba-training com needs to be entered m the Address field for the ClearPass Guest
Answer: C
Explanation:
The correct address for the ClearPass Guest should match the FQDN of the HTTPS certificate installed on the device, which is often the FQDN of the vendor's product. This ensures secureand proper redirection to the captive portal during the authentication process. The FQDN should be entered in the Address field for ClearPass Guest configuration.
NEW QUESTION # 49
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. The AP is configured with LACP active
- B. Each AP interface is connected to a routed-only interlace on different networks
- C. e0 is connected to a smart rate interface, and e1 is connected to a non-smart rate interface.
- D. Spanning tree and loop protect are enabled on both AP uplink ports.
Answer: A
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.
NEW QUESTION # 50
Refer to the exhibit.
Which statement is true?
- A. The client is using BSS Fast Transition
- B. The client performed passive scanning
- C. The client used an incorrect passphrase
- 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.
