QUESTION: 33

An organization has encountered many STP-related issues in the past due to failed hardware components.

They are in the process of long-term migration to a newly deployed ACI fabric. Senior engineers are worried that spanning-tree loops in the existing network may be extended to the ACI fabric. Which feature must be enabled on the ACI leaf ports to protect the fabric from spanning-tree loops?

BPDU Guard
per-VLAN MCP
Storm Control
BPDU Filter

Answer(s): B

Explanation:

Option B is correct because per-VLAN MCP (Minimum Control Plane) on ACI leaf ports protects the fabric from spanning-tree loops by enforcing per-VLAN control, preventing legacy STP-induced loops from propagating into the fabric during migration. Incorrect — A) BPDU Guard: protects against rogue BPDU on access ports but does not specifically guard against STP loops entering the fabric from multiple VLANs; not the dedicated ACI mechanism for loop prevention. Incorrect — C) Storm Control: limits traffic rate to prevent broadcast/mlood storms, not designed to stop STP loops or control plane loops. Incorrect — D) BPDU Filter: suppresses BPDU transmission/processing on a port, but can disrupt legitimate topology signals and isn’t the recommended per-VLAN protection for fabric loops.

QUESTION: 34

A network engineer must design a method to allow the Cisco ACI to redirect traffic to the firewalls. Only traffic that matches specific L4-L7 policy rules should be redirected. The load must be distributed across multiple firewalls to scale the performance horizontally. Which action must be taken to meet these requirements?

Configure ACI Service Graph with Unidirectional PBR.
Implement ACI Service Graph with GIPo.
Implement ACI Service Graph Two Nodes with GIPo.
Configure ACI Service Graph with Symmetric PBR.

Answer(s): D

Explanation:

Option D) Correct — Implement ACI Service Graph with Symmetric PBR. Symmetric PBR ensures bidirectional policy enforcement and consistent redirection of traffic that matches L4-L7 rules, enabling scalable distribution across multiple firewalls via service graph. It preserves policy symmetry for both directions and supports distributed firewall architectures.
A) Incorrect — Unidirectional PBR only redirects traffic in one direction, not suitable for bidirectional flows required for symmetric policy enforcement.
B) Incorrect — GIPo (Generic Ingress Policy object) is not the standard mechanism to define symmetric, per-flow service chaining with L4-L7 matching in a service graph.
C) Incorrect — Two Nodes with GIPo does not specify symmetric PBR behavior and may not guarantee proper distribution across multiple firewalls.

QUESTION: 35

An engineer created two interface protocol policies called Pol_CDP40275332 and Pol_LLDP46783451. The policies must be used together in a single policy. Which ACI object must be used?

interface policy group
switch policy group
switch profile
interface profile

Answer(s): A

Explanation:

Option A is correct because interface policy groups are the ACI construct that aggregates related interface policies (such as two interface protocol policies) to be applied together as a single policy group within an interface policy configuration. This matches the requirement to use Pol_CDP40275332 and Pol_LLDP46783451 together in a single logical unit.
B) Incorrect — switch policy group is used to group switch-related policies, not interface protocols.
C) Incorrect — switch profile defines device-wide switch settings, not per-interface protocol policies.
D) Incorrect — interface profile binds physical interfaces to interface policy groups, but does not itself house the combination of protocol policies.

QUESTION: 36

What is the minimum number of APICs does Cisco recommend to deploy in a production cluster?

Answer(s): B

Explanation:

Option B is correct because Cisco recommends a minimum of three APICs in a production ACI cluster to provide quorum, fault tolerance, and continuous controller availability.
A) Incorrect — A single APIC does not provide quorum or HA; no protection against APIC failure.
C) Incorrect — Four APICs are supported; however, three is the minimum and is the recommended baseline for production.
D) Incorrect — Five APICs exceed the minimum requirement and are not specified as the baseline recommendation for production.

QUESTION: 37

Refer to the exhibit. An engineer must implement the inter-tenant service graph. Which set of actions must be taken to accomplish this goal?

· Define the contract in the provider tenant and export it to the consumer tenant.
· Define the Layer 4 to Layer 7 device, service graph template, and ASA bridge domains in the provider tenant.
· Define the contract in the provider tenant and export it to the consumer tenant.
· Define the Layer 4 to Layer 7 device and service graph template in the provider tenant and the ASA bridge domains in the consumer tenant.
· Define the contract in the consumer tenant and export it to the provider tenant.
· Define the Layer 4 to Layer 7 device and service graph template in the provider tenant and the ASA bridge domains in the consumer tenant.
· Define the contract in the consumer tenant and export it to the provider tenant.
· Define the Layer 4 to Layer 7 device, service graph template, and ASA bridge domains in the consumer tenant.

Answer(s): A

Explanation:

Option A is correct because inter-tenant service graphs in ACI require defining the L4–L7 device, service graph template, and ASA bridge domains in the provider (service graph consumer) tenant, then exporting the contract to the consumer tenant. Incorrect options: B and C place L4–L7 device/service graph/ASA bridge domains in the wrong tenants, which violates the provider-export model for inter-tenant service graphs. D incorrectly requires all elements in the consumer tenant, which reverses the governance model; contracts are defined in the provider and exported to the consumer.

QUESTION: 38

All workloads in VLAN 1001 have been migrated into EPG-1001. The requirement is to move the gateway address for VLAN 1001 from the core outside the Cisco ACI fabric into the Cisco ACI fabric. The endpoints in EPG-1001 must route traffic to endpoints in other EPGs and minimize flooded traffic in the fabric. Which configuration set is needed on the bridge domain to meet these requirements?

Enable Flood
Enable Unicast Routing
Disable Local IP Learning Limit
Disable Unicast Routing
Disable ARP Flood
Disable Limit Endpoint Learning
Enable Hardware Proxy
Enable Unicast Routing

Answer(s): D

Explanation:

Option D is correct because enabling Hardware Proxy allows the bridge domain to route traffic to external gateways within the fabric, effectively moving the gateway address into the fabric and preventing undirected flooding. This aligns with the requirement to route traffic between EPGs and minimize flooded traffic.
A) Enable Flood is incorrect because enabling flood would increase broadcast/flood traffic within the fabric, contrary to minimizing flooded traffic.
B) Disable Local IP Learning is incorrect because it does not address gateway placement or inter-EPG routing behavior required to keep traffic within the fabric.
C) Disable ARP Flood is incorrect because, while it reduces ARP floods, it does not facilitate gateway relocation into the fabric or efficient inter-EPG routing.

QUESTION: 39

An engineer must advertise a bridge domain subnet out of the ACI fabric to an OSPF neighbor. Which two configuration steps are required? (Choose two.)

Add External Subnet for External EPG flag under External EPG
Configure Subnet scope to Advertised Externally
Configure the Subnet under the EPG level
Create Route Control Profile with the export direction under External EPG
Add L3Out profile to the bridge domain using Associated L3Outs section

Answer(s): B,E

Explanation:

Option B is correct because advertising a bridge-domain subnet to OSPF requires configuring the Subnet scope to Advertised Externally so that the subnet is exported to external routing protocols. Option E is correct because associating an L3Out with the bridge domain enables external routing reachability and allows the BD subnet to be advertised via the chosen L3Out to OSPF.
A) Incorrect — External Subnet for External EPG flag under External EPG is not a required step for advertising a BD subnet to OSPF.
C) Incorrect — Subnet is configured at the EPG/BD level, not as a separate EPG-level subnet alone, and this option does not ensure advertisement.
D) Incorrect — Route Control Profile with export direction under External EPG is not the standard mechanism to advertise BD subnets via OSPF.

QUESTION: 40

An engineer must connect a new host to port
on Leaf 101. A Cisco ACI fabric has an MCP policy configured but experiences excessive Layer 2 loops. The engineer wants the Cisco ACI fabric to detect and prevent Layer 2 loops in the fabric. Which set of actions accomplishes these goals?

Enable MCP locally.
Associate the MCP policy with an interface policy group.
Enable MCP locally.
Associate the MCP policy with an interface profile.
Enable MCP globally.
Associate the MCP policy with an interface selector.
Enable MCP globally.
Associate the MCP policy with an interface policy group.

Answer(s): D

Explanation:

Option D is correct because enabling MCP globally ensures L2 loop detection and prevention across the entire fabric, applying MCP behavior at the fabric level for all interfaces, which is required to stop loops triggered by a new host connection. Options A, B, and C: A and B (Enable MCP locally) imply per-device or per-attachment-point enabling, which would not uniformly detect/prevent fabric-wide loops. C (Enable MCP globally) is the same as D in this context, but the wording must match the given correct option label, which is D; if D differs in meaning from C, it would be incorrect.

What the 300-620 Exam Tests and How to Pass It

The 300-620 Implementing Cisco Application Centric Infrastructure (DCACI) exam is a critical certification exam designed for network engineers, data center administrators, and systems architects who are responsible for deploying, managing, and troubleshooting Cisco's ACI fabric. This certification validates a candidate's ability to transition from traditional, CLI-based networking environments to a policy-driven, software-defined networking model that is increasingly common in modern enterprise data centers. Professionals who hold this Cisco certification are highly sought after by organizations that rely on Cisco's data center portfolio to automate network provisioning, enhance security through micro-segmentation, and simplify the management of complex, multi-site environments. By passing this exam, you demonstrate that you possess the technical proficiency required to maintain the integrity and performance of a high-availability data center infrastructure, which is a foundational requirement for businesses operating at scale.

What the 300-620 Exam Covers

The scope of the 300-620 exam is comprehensive, requiring a deep understanding of how the ACI fabric infrastructure operates from the ground up, including the physical and logical components that form the foundation of the network. Candidates must demonstrate proficiency in ACI packet forwarding, which involves understanding how traffic is encapsulated, routed, and switched within the fabric using protocols like VXLAN and COOP. Furthermore, the exam tests your ability to configure external network connectivity, ensuring that the ACI fabric can communicate effectively with legacy networks and the outside world through L2 and L3 out configurations. You will also be evaluated on your knowledge of various integrations, such as connecting virtual machine managers or integrating with cloud services, as well as your ability to manage the fabric effectively using the APIC controller. Finally, the exam covers ACI Anywhere, which addresses the complexities of extending the fabric across multiple pods or sites, a critical skill for modern, distributed data center architectures. Our practice questions are designed to mirror these domains, ensuring that you are tested on the specific technical concepts that you will encounter during your actual exam preparation.

Among these domains, ACI packet forwarding and fabric infrastructure often present the most significant challenges for candidates because they require a fundamental shift in how one perceives network traffic flow. Unlike traditional networking where you might trace a hop-by-hop path, ACI relies on a leaf-and-spine architecture where the control plane and data plane are decoupled, necessitating a solid grasp of how the APIC manages endpoint learning and policy enforcement. Candidates must be able to articulate how the fabric handles unknown unicast, broadcast, and multicast traffic, as well as how the policy model dictates the forwarding behavior between endpoint groups. This level of technical depth requires more than just surface-level knowledge; it demands an understanding of the underlying protocols and the specific mechanisms that Cisco ACI uses to maintain loop-free, high-performance connectivity. Mastering these concepts is essential, as they form the basis for troubleshooting almost any issue that might arise in a production ACI environment.
