An OSPF router has learned a pain 10 an external network by Doth an E1 and an E2 advertisement Both routes have the same path cost Which path will the router prefer?

  1. The router will prefer the E1 path.
  2. The router will use Doth paths equally utilizing ECMP.
  3. The router will prefer the E2 path.
  4. Both routes will be suppressed until the path conflict has been resolved.

Answer(s): A

Explanation:

In OSPF, when a router learns about an external network through both E1 and E2 advertisements, and if both have the same path cost, the router will prefer the E1 path. This is because E1 routes consider both the external cost to reach the external network and the internal cost to reach the ASBR, providing a more comprehensive metric. E2 routes only consider the external cost and ignore the internal cost to the ASBR, which could potentially lead to suboptimal routing. Therefore, the router will choose the E1 path due to its more accurate representation of the total path cost.



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.
