Cisco 300-620 Dumps - Pass Implementing Cisco Application Centric Infrastructure Exam in 2026

The Cisco 300-620 exam, Implementing Cisco Application Centric Infrastructure, is part of the Cisco Certified Network Professional, Cisco Certified Network Professional Data Center, and Cisco Specialist certification paths. It is designed for network professionals who want to validate their ability to deploy, manage, and troubleshoot Cisco ACI environments. This exam matters because ACI skills are essential for modern data center automation, policy-based networking, and scalable infrastructure operations.

This page is built for candidates who want focused preparation for the Cisco 300-620 certification exam with practical study support and exam-style content.

Exam Topics and Approximate Weightage

# Exam Topics Sub-Topics Approximate Weightage (%)
1 ACI Fabric Infrastructure Leaf and spine architecture, fabric discovery, APIC basics, policy model fundamentals 22%
2 ACI Packet Forwarding Bridge domains, endpoint learning, flooding behavior, forwarding within the fabric 18%
3 External Network Connectivity L3Out configuration, routing integration, external EPGs, contract-based connectivity 18%
4 Integrations Virtualization integration, automation tools, API usage, orchestration workflows 15%
5 ACI Management Tenant administration, monitoring, troubleshooting, operational visibility 17%
6 ACI Anywhere Policy consistency, multi-site concepts, remote connectivity, architecture extension 10%

The Cisco 300-620 exam tests how well candidates understand ACI design concepts, fabric operations, packet flow, external connectivity, and management tasks. It also evaluates practical knowledge of integrations and broader ACI deployment scenarios. Success requires more than memorization because the exam checks your ability to apply concepts in real-world data center environments.

Actual Cisco 300-620 Exam Questions

Question 2

An ACI engineer is implementing a Layer 3 out inside the Cisco ACI fabric that must meet these requirements:

The data center core switch must be connected to one of the leaf switches with a single 1G link.

The routes must be exchanged using a link-state routing protocol that supports hierarchical network design.

The data center core switch interface must be using 802.1Q tagging, and each vlan will be configured with a dedicated IP address.

Which set of steps accomplishes these goals?

Correct answer: C

To implement a Layer 3 out (L3Out) inside the Cisco ACI fabric that meets the specified requirements, the following steps should be taken:

Configure the OSPF Protocol policy with an area of 0: This step involves setting up OSPF, a link-state routing protocol that supports hierarchical network design, as the routing protocol for the L3Out1.

Create Routed Outside object and Node Profile, selecting OSPF: This step involves creating a Routed Outside object and associating it with a Node Profile that specifies OSPF as the routing protocol1.

Build the Interface profile, selecting Routed Sub-interface and the appropriate VLAN: This step involves creating an Interface profile for the connection to the data center core switch, using 802.1Q tagging for VLAN separation2.

Configure the External Network object with a network of 0.0.0.0/0: This step involves setting up the External Network object to advertise routes to the rest of the network1.


Question 3

An engineer created a monitoring policy called Test in a Cisco ACI fabric and had to change the severity level of the monitored object Call home source. Which set of actions prevent the event from appearing in event reports?

Correct answer: C

Question 4

A network engineer must allow secure access to the Cisco ACl out-of-band (OOB) management only from external subnets 10 0 0024 and 192.168 20 G'25. Which configuration set accomplishes this goal?

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.

Question 5

A network engineer must configure a Cisco ACI system to detect network loops for untagged and tagged traffic The loop must be detected and slopped by disabling an interface within 4 seconds Which configuration must be used?

Correct answer: B

To configure a Cisco ACI system to detect network loops for both untagged and tagged traffic and to stop the loop by disabling an interface within 4 seconds, the following configuration must be used:

Enable Mis-Cabling Protocol (MCP): MCP detects loops from external sources and will err-disable the interface on which Cisco ACI receives its own packet.This is crucial for preventing loops in the network1.

Configure MCP Transmit Frequency: Set the MCP transmit frequency to a value that allows for quick loop detection. The Cisco ACI fabric provides faster loop detection with transmit frequencies from 100 milliseconds to 300 seconds.To meet the requirement of detecting and stopping a loop within 4 seconds, you would set the transmit frequency to a value less than 4 seconds2.

Set Action on Loop Detection: Configure the MCP policies to identify loops and decide how to act upon them.You can set the policy to generate a syslog message or disable the port upon loop detection2.

Implement Error Disabled Recovery Policy: Configure an error disabled recovery policy to automatically re-enable ports that were disabled due to loop detection after a configurable interval2.

By implementing these configurations, the Cisco ACI system will be able to detect and stop network loops quickly and efficiently, ensuring network stability and preventing potential disruptions.

Frequently Asked Questions

Who should take the Cisco 300-620 exam?

This exam is for network and data center professionals who want to validate skills in Cisco Application Centric Infrastructure as part of Cisco Certified Network Professional, Cisco Certified Network Professional Data Center, or Cisco Specialist paths.

Is the Cisco Implementing Cisco Application Centric Infrastructure exam difficult?

It can be challenging because it covers fabric infrastructure, forwarding, connectivity, integrations, and management. Candidates who understand the concepts and practice with exam-style questions usually feel more prepared.

Can I pass Cisco 300-620 with only braindumps?

Relying only on dumps is not the best approach. You should use them as a study aid together with conceptual review and practical understanding so you can answer scenario-based questions with confidence.

Do I need hands-on experience with Cisco ACI?

Hands-on experience is very helpful because the exam focuses on real implementation and operational knowledge. Even if you use study materials, practical exposure makes the topics easier to understand.

Are QA4Exam.com dumps enough to pass on the first attempt?

QA4Exam.com dumps and the Online Practice Test can greatly improve your preparation, but the best results come from combining them with topic review and practice. That approach helps you build accuracy, speed, and confidence for a first attempt.

What is included in the QA4Exam.com Cisco 300-620 practice test format?

The practice test is designed to simulate the exam experience with realistic questions, verified answers, and a structure that helps you practice under time pressure. It is useful for checking readiness before the real exam.

What if I fail the Cisco 300-620 exam on the first try?

If you do not pass on the first attempt, review the topics you missed, practice again with exam-style questions, and strengthen your understanding of the ACI concepts. A better preparation plan can improve your next attempt.
