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?

  1. Add a new Enforcement Policy of type `'WEBAUTH'' on ClearPass and associate it with the matching service on ClearPass
  2. Add the correct IP addresses or IP subnets of the Network Access Devices (NADs) under the "Devices" tab on ClearPass
  3. Replace the AP's expiree digital certificate using the "crypto pki-import pem serverCert" command.
  4. Add the correct values for "CPPM username" and "CPPM Password" m the authentication server configuration on HPE Aruba Networking Central

Answer(s): 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.



Which data transmission method provides the most efficient use of airtime for VoIP traffic?

  1. FDMA
  2. OFDM
  3. MU-MIMO
  4. TWT

Answer(s): C

Explanation:

MU-MIMO (Multi-User, Multiple Input, Multiple Output) provides the most efficient use of airtime for VoIP traffic among the options listed. MU-MIMO allows multiple users to receive multiple data streams simultaneously, improving the overall efficiency of the network, especially in dense environments where VoIP applications need consistent and reliable connectivity.



You deployed UBT to securely tunnel traffic from user desktop PCs connected behind VOIP phones Ail other non-UBT dents are connected to a different network. After the deployment users reported interruptions lo their phone service

  1. The VLAN on which UBT clients are placed is not configured on the switch uplink and traffic from the VoIP phones is being dropped
  2. You tailed to correctly configure a user-defined VRF to support the UBT clients behind the VoIP phones, causing traffic to drop.
  3. Broadcast/multicast packets are copied to both the tunnel and locally, causing duplicate packets and network instability
  4. The UBT client broadcast/multicast packets returned to the same switch port and corrupted the phones IMC table

Answer(s): A

Explanation:

If users report interruptions to their phone service after the deployment of User-Based Tunneling (UBT), it can be due to the VLAN designated for UBT clients not being configured on the switch uplink. As a result, traffic from VoIP phones, which may be trying to use the same VLAN, could be dropped, leading to service interruptions. Ensuring that the VLAN is properly configured on the switch uplink is crucial for the seamless operation of UBT clients and VoIP services.



An ACME company employee complained about a recent poor-quality VoIP call while moving around their office environment HPE Aruba Networking Central reported a fair UCC score for this call while your VoIP engineer reported that their systems reported a MOS of 2, 3. The VoIP devices are operating over the 5GHz frequency band.
What are the possible contributing factors? (Select two.)

  1. Coverage AP deployment plans generally don't support enough cell overlap for VoIP.
  2. 802.tr is enabled in the WLAN Security settings.
  3. There was localized interference at the caller's location
  4. 802.1K is disabled in the WLAN Security settings
  5. The client roamed into an area that continuously operates Zigbee.

Answer(s): A,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.



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?

  1. Disable 802 11r.
  2. Disable 802 11k.
  3. increase 5Gnz TX power range Min/Max.
  4. increase 5 GHz wireless coverage tuning to Aggressive.

Answer(s): C

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.
