ACI Anywhere and multi site concepts showed up enough that I am glad I reviewed policy consistency and connectivity expectations across sites, and I passed the Implementing Cisco Application Centric Infrastructure exam. Short scenario based practice questions helped me translate the architecture into decisions under time pressure.

Management topics frequently appear as API or GUI workflow scenarios where you must choose the correct REST calls or identify which APIC policy will resolve a given fault. Spend time with APIC REST examples, health score interpretation, and role-based access control so you can reason through troubleshooting-style questions.

Integration questions can be very specific, asking how VMM domains, vCenter objects, or Kubernetes annotations map into bridge domains and endpoint groups. Understand VMM registration, host-link mappings, and policy propagation limits, someone I know passed and specifically thanked Pass4Success for a compact collection of questions that saved time.

External connectivity was the trickiest section for me, so I focused on L3Out design, route leaking, and common BGP and OSPF pitfalls before sitting the exam, and I managed to pass. The best prep was reviewing real config examples and understanding why each knob exists rather than memorizing steps.

External network connectivity problems often test L3Out design and troubleshooting with BGP or OSPF and NAT in multi-step configuration-to-failure scenarios. Study route leaking, how contracts interact with external policies, and common L3Out mistakes, a colleague passed after concentrated lab work and targeted question practice.

Packet forwarding items usually come as packet-trace problems that force you to follow encapsulation, VTEP behavior, and contract enforcement to explain dropped traffic. Practice tracing frames through bridge domains and EPGs and learn when hardware versus software forwarding applies.

The 300-620 leaned heavily on ACI fabric basics, so I spent extra time on leaf spine roles, policy constructs, and fault interpretation in the APIC GUI, and I passed on the first try. What helped most was building a small lab and practicing common bring up checks until they were automatic.

Fabric infrastructure questions often present a topology scenario where you must determine which component handles control plane functions or how endpoint discovery works.

Free Cisco 300-620 Exam Actual Questions

Note: Premium Questions for 300-620 were last updated On Oct. 06, 2026 (see below)

Question #1

What is the name of the automatically configured VLAN 3600 presented during Cisco ACI fabric discovery?

Reveal Solution Hide Solution
Correct Answer: B

The Infrastructure VLAN is automatically configured during the Cisco ACI fabric discovery process. This VLAN, often referred to as the ''infra VLAN,'' is used to enable internal communication between the ACI fabric components, such as the leaf and spine nodes. It is vital for the overlay network and the control plane functionality. In the provided output, VLAN 3600 represents the Infrastructure VLAN, which is configured for inter-node communication.


Question #2

Refer to the exhibit A Cisco ACI fabric is using out-of-band management connectivity The APIC must access a routable host with an IP address of 192 168 11 2 Which action accomplishes this goal?

Reveal Solution Hide Solution
Correct Answer: C

To enable the APIC in a Cisco ACI fabric using out-of-band management connectivity to access a routable host with an IP address of 192.168.11.2, you need to add a Fabric Access Policy that allows management connections. This involves configuring a contract that will be consumed and provided to your OOB devices. The contract will let the system know what traffic is allowed. In this case, you will use the default/common contract to permit any traffic.This is necessary because the APIC needs to be able to send traffic to and receive traffic from the management network1.

Troubleshoot ACI Management and Core Services - In-band and Out-of-band Management - Cisco2

Question #3

An engineer is implementing a Cisco ACI environment that consists of more than 20 servers. Two of the servers support only Cisco Discovery Protocol with no order link discovery protocol. The engineer wants the servers to be discovered automatically by the Cisco ACI fabric when connected. Which action must be taken to meet this requirement?

Reveal Solution Hide Solution
Correct Answer: A

To ensure that servers supporting only Cisco Discovery Protocol are discovered automatically by the Cisco ACI fabric when connected, the action that must be taken is toCreate an override policy that enables Cisco Discovery Protocol after LLDP is enabled in the default policy group


Question #4

When does the Cisco ACI leaf learn a source IP or MAC as a remote endpoint?

Reveal Solution Hide Solution
Correct Answer: D

In Cisco ACI, a leaf switch learns a source IP or MAC as a remote endpoint when VXLAN traffic arrives on a leaf fabric port from the spine, and the inner source IP is within the range of the bridge domain subnets associated with the leaf. This process is part of the ACI's COOP (Council Of Oracles Protocol), which ensures that endpoint information is accurately disseminated across the fabric for efficient traffic forwarding.


Question #5

A company is implementing a new security policy to track system access, configuration, and changes. The network engineer must enable the log collection to track user login and logout attempts. In addition, any configuration changes such as a fabric node failure must be collected in the logs. The syslog policy is configured to send logs to the company SEIM appliance. Which two log types must be enabled to meet the security requirements? (Choose two.)
