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?
Answer : D
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.
You are troubleshooting a WLAN deployment with APs and gateways set up with an 802.1X tunneled SSIO. End-users are complaining that they can't connect to die enterprise SSID. Which possible AP tunnel states could be the cause of the Issue? (Select two.)
Answer : A, E
When troubleshooting a WLAN with 802.1X tunneled SSID issues, AP tunnel states indicate the status of the connection between the AP and the gateway/controller. The states 'SM_STATE_REKEYING' and 'SM_STATE_CONNECTING' could indicate transitional states where the connection has not been fully established, hence users might face issues connecting to the SSID. 'SM_STATE_REKEYING' implies that the AP is in the process of re-establishing encryption keys, while 'SM_STATE_CONNECTING' indicates that the AP is trying to establish a connection with the controller or gateway. These states could lead to temporary connectivity issues until the state transitions to 'SM_STATE_CONNECTED'.
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?
Answer : D
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
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 of their 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?
Answer : D
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.
in a WLAN network with a tunneled SSID. you see the following events in HPE Aruba Networking Central:

The customer asks you to investigate log messages What should you tell them?
Answer : B
The event log showing PMK (Pairwise Master Key) and OKC (Opportunistic Key Caching) key add/update and delete operations is indicative of normal client behavior in a WLAN environment. These events are part of the standard process for maintaining client session security and do not necessarily indicate any issue.
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?
Answer : B
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.
A campus topology uses VSX with a collapsed core topology. The customer added redundant SFP+ transceivers and reconfigured their mobility gateways from a single link to an aggregate Link. You are asked to verify the CLI output for the link aggregation configuration for one of the mobility gateway cluster members below.

What is a valid configuration?
A)

B)

C)

D)

Answer : A
The configuration shown in Option A is a valid configuration for a multi-chassis link aggregation (MC-LAG) setup. It specifies the use of LACP (Link Aggregation Control Protocol) with a fast rate of LACP PDUs exchange, which is appropriate for creating a resilient and high-throughput link aggregation. The 'vlan trunk allowed all' command allows all VLANs across the trunk, and 'vlan trunk native 100' sets VLAN 100 as the native VLAN for untagged traffic.
