                                                    The H12-321 exam contains 60-70 questions and gives you 90 minutes to finish them. Before exam day, divide the total time by the question count so you know the pace you need to keep, and flag difficult items instead of getting stuck on them. Running at least one full timed session in the Actual4test test engine is the best way to make that time pressure feel familiar.

                                                    You need 600/1000 to pass, and the official registration fee is 160 USD. Keep in mind that a failed attempt means paying that fee in full again, so it pays to test yourself first. When your scores on the Actual4test timed practice tests stay consistently above the passing line, you are ready to book the exam.

                                                    Question 1

                                                    In the load balancing mode, what is the correct way for the RADIUS/Portal server to handle hot standby?

                                                    A. Fill in the backup NAS-IP-Address and billing session-id in the accounting and authentication packets.

                                                    C. The original master node DOWN/uplink interrupt, the COA/DM packet received by the node needs to be processed and synchronized to the peer end. The master device needs to send the authorization information to the AP.
                                                    If the original primary node is not the DOWN/uplink interrupt, the backup node is also configured with a loopback interface with the same IP address as the primary node. The interface is not directly added to the IGP but is imported through import direct.
