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?

AEnter the command 'pot-access device-profile mode block-until-profile-applied'' for interface 1/1/1.

BEnter the command 'port-access fallback-role lot-default globally

CEnter the command 'port-access onboarding-method precedence' to set device profiles with a lower precedence.

DEnter the command 'port-access device-profile mode block-until-profile-applied' globally.

Answer : B

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

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?

AOption A

BOption B

COption C

DOption 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.

Question 3

What directly affects the MCS used by wireless stations? (Select two.)

ASNR

Bretry rate

Cchannel utilization

Dnumber of connected clients

Efrequency band

Answer : A, E

The Modulation and Coding Scheme (MCS) used by wireless stations is directly affected by the signal-to-noise ratio (SNR) and the frequency band. Higher SNR can lead to higher MCS values, which means better data rates. The frequency band can affect MCS due to different channel characteristics, such as the presence of interference and propagation properties, which are factors in determining data rates.

Question 4

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?

AThe router will prefer the E1 path.

BThe router will use Doth paths equally utilizing ECMP.

CThe router will prefer the E2 path.

DBoth routes will be suppressed until the path conflict has been resolved.

Answer : A

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.

Question 5

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?

AAdd a new Enforcement Policy of type ''WEBAUTH'' on ClearPass and associate it with the matching service on ClearPass

BAdd the correct IP addresses or IP subnets of the Network Access Devices (NADs) under the 'Devices' tab on ClearPass

CReplace the AP's expiree digital certificate using the 'crypto pki-import pem serverCert' command.

DAdd the correct values for 'CPPM username' and 'CPPM Password' m the authentication server configuration on HPE Aruba Networking Central

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.

Question 6

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

* MAC address = 81:cd:93:13:ab:31

* LLDP sys-desc = iotcontroller

The test device is being assigned to the ''lot-dev'' role However, the customer requires the "lot-prod'' role be applied.

Given the configuration, what is causing the "iot-dev" role to be applied to the device'?

AThe test device does not support CDP.

BThe device-profile precedence order is not configured.

CAn external RADIUS server is unreachable.

DThe LLDP system description matches the IIdp-group configuration.

Answer : D

In device profile configuration, the device role is often determined by matching attributes such as MAC address, LLDP system description, and CDP information against defined conditions. The test device is being assigned the 'iot-dev' role because its LLDP system description matches the 'iot-lldp' group configuration that is associated with the 'iot-dev' role.

Question 7

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?

AYou need to include the root and intermediate certificates in the captive portal certificate for your access points

BYou need to De connected to the guest SSiD while testing.

CYou need to change the Login Address in ClearPass to securelogin arubanetworKs.com

DYou need to include the root and intermediate certificates in the captive portal certificate for your gateway

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.
