Identify the required configuration steps to enable DHCP EndpointProfiling with HPE Aruba Networking ClearPass. (Not all will be used)

Correct Answer:

Explanation:

To enable DHCP Endpoint Profiling, the switch needs to forward relevant DHCP packets from the client to the ClearPass server. The most common method is configuring the switch to act as a DHCP relay agent for the ClearPass server IP address on the client VLAN's Switched Virtual Interface (SVI).
In scenarios where port access control (like 802.1X or MAC Auth) is enabled, clients might need to send DHCP requestsbeforethey are fully authenticated. To allow this while maintaining security, a pre- authentication role with limited access (specifically allowing DHCP) can be applied to the port initially.
The logical sequence based on the provided steps, assuming a pre-authentication workflow is intended, is:
* Create the role:Define the pre-authentication role container and associate it with the appropriate initial VLAN if needed.
* Permit DHCP in the role:Apply an Access Control List (ACL) or policy to this role that permits the necessary DHCP traffic (UDP ports 67 and 68). The step provided only mentions UDP 67, which allows the client's initial Discover/Request packets towards the server/relay. (A complete solution requires allowing return traffic on UDP 68 as well).
* Apply the role:Configure the client-facing physical interface to use this pre-authentication role before the final role is assigned post-authentication.
* Configure DHCP Relay:Configure the ip helper-address <clearpass_ip> command on the client's VLAN SVI. This instructs the switch to forward the DHCP packets it receives from clients in that VLAN to the ClearPass server (in addition to forwarding them to the actual DHCP server). ClearPass receives these packets and extracts information for profiling.
This sequence ensures that even before full authentication, DHCP is permitted, and the necessary packets are relayed to ClearPass for profiling.

Place the recommended troubleshooting steps in order.

Correct Answer:

Explanation:
The correct order is:
* identify
* analyze
* hypothesize
* validate
* implement
* verify
This question requires arranging standard troubleshooting steps into a logical sequence. A systematic approach is crucial for effective network troubleshooting.
* identify:The first step is always to clearly identify and define the problem. What are the symptoms?
Who is affected? What is the scope? When did it start? Understanding the problem precisely is essential before proceeding.
* analyze:Once the problem is identified, gather relevant data and analyze the situation. This involves checking logs, looking at configurations, examining network topology diagrams, checking status commands, and potentially capturing packets. This analysis helps build context around the identified issue.
* hypothesize:Based on the identification and analysis, form a hypothesis (or multiple hypotheses) about the probable cause of the problem. This involves using technical knowledge and experience to theorize what might be wrong.
* validate:Test the hypothesis to determine if it's correct. This step involves performing specific tests or checks designed to confirm or refute the theory. For example, if the hypothesis is a bad cable, test the cable. If it's a routing issue, check the routing table and perform trace routes. This step validates the cause before implementing a fix.
* implement:Once the cause has been validated, implement the solution. This could involve replacing hardware, correcting configuration, clearing states, etc.
* verify:After implementing the solution, verify that the original problem is resolved. It's also critical to check that the fix hasn't introduced any new issues. Monitor the system to ensure stability.
