Suggested answer

For a Cisco ACI data center network, when integrating Cisco Nexus 2000 Series 10G fabric extenders, the physical topology needs to ensure proper connectivity and communication between the devices. The correct topology for such an implementation is depicted in Diagram D. In this topology, each FEX (Nexus 2000 Series) is directly connected to one parent switch (Nexus 9000 Series). This setup ensures efficient and reliable network performance, adhering to Cisco's best practices for ACI setups. Diagrams A, B, and C show different forms of connectivity that don't align with the recommended single-parent switch connection for each FEX.

Question 2 of 404

An ACI administrator notices a change in the behavior of the fabric. Which action must be taken to determine if a human intervention introduced the change?

Answer choices
Show answer

Correct answer: C

To determine if human intervention introduced a change in the behavior of the ACI fabric, it is necessary to inspect the audit logs in the APIC UI. The audit logs track user actions and configuration changes, enabling administrators to identify any modifications made by users. This makes them the most appropriate resource for understanding human interactions with the system.

Question 3 of 404

An engineer is creating a configuration import policy that must terminate if the imported configuration is incompatible with the existing system. Which import mode achieves this result?

Answer choices
Show answer

Correct answer: B

The configuration import mode that terminates if the imported configuration is incompatible with the existing system is 'atomic.' In atomic mode, the configuration is applied as a whole, and any error in the process will cause the entire import to be rolled back, ensuring that the system does not end up in an inconsistent state.

Question 4 of 404

Which components MUST be configured for the BGP Route Reflector policy to take effect?

Answer choices
Show answer

Correct answer: C

To configure the BGP Route Reflector policy in a Cisco ACI environment, the appropriate components to configure are pod policy groups and profiles. These settings are essential for ensuring the route reflector function operates correctly within the pod framework, which handles the intra-fabric routing. By specifying policies at the pod level, you can control and manage route reflection rules efficiently across the ACI fabric.

Question 5 of 404

Which type of policy configures the suppression of faults that are generated from a port being down?

Answer choices
Show answer

Correct answer: A

A fault lifecycle assignment policy is designed to configure and manage the suppression of faults, such as those generated from a port being down. This type of policy deals directly with the lifecycle of faults, including their creation, suppression, and overall management within the system.

Stories from the certified

As this was my first certification exam, I was understandably nervous about what to expect. These study materials made the preparation process much easier, and many of the questions closely reflected those on the actual exam.

Wasted about a month going through the free dump sites scattered all over reddit, half the answers were wrong and the other half were for a version of the exam that doesn't even exist anymore. Eventually gave in and paid the small fee here, and the difference was night and day.

Honestly, I had already gone through the official documentation quite thoroughly, but still didn't feel fully confident going in. This helped things finally click for me. I realized I knew the material, but just hadn't connected all the pieces yet.
