QUESTION: 1

A customer is evaluating device profiles on a CX 6300 switch. The test device has the following attribute:

· MAC address=81:cd:93:13:ab:31
The test device needs to be assigned the "lot-prod'' role, in addition the "lot-default" role must be applied for any other device connected lo interface 1/1/1. This is a lab environment with no configuration of any external authentication server for the test. Given the configuration example, what is required to meet this testing requirement?

Enter the command "pot-access device-profile mode block-until-profile-applied"" for interface 1/1/1.
Enter the command "port-access fallback-role lot-default globally
Enter the command "port-access onboarding-method precedence" to set device profiles with a lower precedence.
Enter the command "port-access device-profile mode block-until-profile-applied" globally.

Answer(s): B

Explanation:

The fallback role is used as a default role in the absence of a specified role or when an authentication server is not available. Given the scenario, where the test device with MAC address 81:cd:93:13:ab:31 needs to be assigned to "iot-prod" and other devices to "iot-default", and considering there is no external authentication server configured for the test, the appropriate action would be to set a global fallback role that applies to all devices connecting to the network. This ensures that any device that does not match the specific device profile will inherit the "iot-default" role. Since the configuration for a specific MAC address (81:cd:93:xx:xx:xx) to associate with the "iot- prod" role is already in place, setting the fallback role globally accommodates the requirement for other devices.

QUESTION: 2

Exhibit.

Which user role will be assigned when a voice client tries to connect for the first time, but the RADIUS server is unavailable?

CRITICAl_AUTH
DEFAULT_AUTH
CRIT1CAL_V0ICE
PRE_AUTH

Answer(s): C

Explanation:

In the provided configuration for interface 1/1/7, there are roles specified for different scenarios concerning authentication.
When a voice client attempts to connect and the RADIUS server is unreachable, the role that is assigned is the one specified as the "critical-voice-role". In this case, the "CRITICAL_VOICE" role is configured to be assigned under such circumstances, ensuring that voice clients receive appropriate network access permissions even when the RADIUS server is not available to authenticate them.

QUESTION: 3

You configured a WPA3-SAE with the following MAC Authentication Role Mapping in Cloud Authentication and Policy:

With further default settings assume a new Android phone is connected to the network.
Which role will the client be assigned after connecting for the first time?

byod
client will be rejected network access
lot-local
unmatched-device

Answer(s): D

Explanation:

The configuration shown in the third exhibit details a client role mapping that associates different client profile tags with specific client roles.
When a new device, such as an Android phone, connects to the network, it will be profiled and assigned a role based on the mappings defined. If the device does not match any predefined profiles, it would be assigned the "unmatched-device" role. This is under the assumption that default settings are in place and the client does not match the criteria for any of the specific roles like "byod", "iot-internet", or "iot-local". Therefore, an Android phone connecting for the first time and not matching any specific profile tag would be assigned to the "unmatched-device" role.

QUESTION: 4

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?

The RadSec server was defined on the switch using an IPv6 address that was unreachable
Tracking mode was set to "dead-only", and the RadSec server was marked as unreachable.
The switch is configured to establish a TLS connection with a proxy server, not the radius server.
The RADIUS TCP packets are Being dropped and the TLS tunnel is not established.

Answer(s): D

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
