DCACI 300-620 is a 90-minute, ~55-65 question CCNP Data Center concentration exam delivered by Pearson VUE for US$300. The official v1.2 blueprint is weighted 20% ACI Fabric Infrastructure, 15% ACI Packet Forwarding, 20% External Network Connectivity, 15% Integrations, 20% ACI Management, and 10% ACI Anywhere. There are no formal prerequisites, although Cisco recommends valid CCNA-level knowledge and hands-on Cisco ACI experience. Passing DCACI plus the 350-601 DCCOR core earns the CCNP Data Center certification, and DCACI alone earns a Cisco Certified Specialist credential. Cisco certifications remain valid for three years.

1What is the recommended minimum number of APIC controllers for a production Cisco ACI fabric cluster?
A.1
B.2
C.3
D.5
Explanation: Cisco requires a minimum of three APIC controllers in a production cluster to provide quorum for the distributed multi-active database that uses sharding. Recommended cluster sizes are 3, 5, or 7; cluster sizes of 4 and 6 are explicitly not recommended.
2Which routing protocol does the ACI fabric use in the infra VRF (overlay-1) for spine-leaf reachability?
A.OSPF
B.EIGRP
C.IS-IS
D.BGP
Explanation: The ACI fabric runs IS-IS in the infra VRF (overlay-1) to exchange TEP (tunnel endpoint) reachability between leaf and spine nodes. MP-BGP runs as an overlay for endpoint reachability inside tenant VRFs, but the underlay routing in overlay-1 is IS-IS.
3In the ACI Object Model, what does a Distinguished Name (DN) uniquely identify?
A.The relative position of an object within its parent
B.A managed object's globally unique location in the management information tree
C.The class name of an object
D.The fault severity associated with an object
Explanation: The Distinguished Name (DN) is the full hierarchical path that uniquely identifies a managed object (MO) in the ACI Management Information Tree (MIT). It is composed of one or more Relative Names (RNs) concatenated from root down to the object.
4Which fault severity level in ACI indicates a service-affecting condition that requires immediate attention?
A.Warning
B.Minor
C.Major
D.Critical
Explanation: ACI fault severities are Critical, Major, Minor, and Warning. Critical is the highest severity and indicates a service-affecting condition that needs immediate operator attention. Faults are visible in the GUI under System > Faults and stored as faultInst objects.
5Which protocol does ACI use during fabric discovery to identify directly connected fabric neighbors?
A.CDP
B.LLDP
C.STP
D.BFD
Explanation: ACI uses LLDP (Link Layer Discovery Protocol) on fabric ports for switch and APIC discovery. LLDP carries TLVs that allow APIC to identify leaf and spine roles, build the topology, and assign node IDs and TEP addresses through bootstrap.
6Which ACI logical construct provides Layer 3 separation similar to a traditional VRF and contains one or more Bridge Domains?
A.Tenant
B.VRF (Context)
C.Application Profile
D.Endpoint Group
Explanation: A VRF (also called a Context) inside an ACI tenant provides a Layer 3 routing domain. One or more Bridge Domains attach to a VRF, and subnets are routed within that VRF. Multiple VRFs can exist within a single tenant for multi-tenancy.
7Which scope on an ACI contract limits its applicability to EPGs within the same VRF only?
A.Global
B.Tenant
C.VRF
D.Application Profile
Explanation: Contract scope controls how broadly the contract can be consumed/provided. Scope VRF (Context) limits the contract to EPGs sharing the same VRF. Larger scopes (Tenant, Global) widen applicability, while Application Profile narrows it further.
8Which ACI feature allows all EPGs within a VRF to communicate freely without explicitly defining contracts between every pair?
A.Preferred Group
B.Contract Inheritance
C.vzAny
D.ESG Selectors
Explanation: vzAny is a logical construct that represents 'any EPG in a VRF.' Configuring a contract on vzAny applies it to every EPG in that VRF as both provider and consumer, which scales policy without per-EPG entries and is the preferred way to allow free intra-VRF communication.
9What is the primary advantage of an Endpoint Security Group (ESG) over a traditional EPG?
A.ESGs eliminate the need for VRFs
B.ESGs decouple security policy from the network forwarding (Bridge Domain) construct
C.ESGs only work in stretched fabrics
D.ESGs replace the APIC database
Explanation: ESGs decouple Layer 3/Layer 4 security policy from forwarding. While EPGs are tightly tied to a single Bridge Domain, ESGs span EPGs/BDs within a VRF and use selectors (IP, tag, EPG) to classify endpoints, simplifying policy across application tiers.
10Which APIC policy object groups VLAN pools, AAEPs, and domains so they can be applied consistently to leaf access ports?
A.Switch Profile
B.Leaf Interface Profile
C.Leaf Access Port Policy Group
D.Pod Profile
Explanation: A Leaf Access Port Policy Group bundles interface-level policies (CDP, LLDP, LACP, link level) with the AAEP, which in turn references domains and VLAN pools. The policy group is applied to ports through Interface Selector objects under a Leaf Interface Profile.

Cisco DCACI 300-620 Study Tips from Top Performers

1Build a small ACI lab in dCloud or Cisco Modeling Labs and walk through APIC bootstrap, fabric discovery via LLDP, tenant/VRF/BD/EPG creation, and contract enforcement end to end.
2Memorize APIC cluster sizing rules: 3, 5, or 7 APICs are supported; 4 and 6 are explicitly NOT recommended due to sharding behavior.
3Master the BD knobs: L2 Unknown Unicast (Hardware Proxy default vs Flood), Unicast Routing on/off, ARP Flooding on/off, and Multi-Destination Flooding scope (BD/Encap/Drop).
4Drill the External EPG flags: 'External Subnets for the External EPG' classifies, 'Export Route Control Subnet' redistributes outbound, 'Import Route Control' applies when import enforcement is enabled.
5Know Resolution Immediacy (Pre-provision/Immediate/On Demand) and Deployment Immediacy (Immediate/On Demand) cold; the exam tests when each is appropriate for VMM domains.
6Compare Multi-Pod vs Multi-Site clearly: one APIC cluster across pods (Multi-Pod) versus separate APIC clusters per site orchestrated by NDO with BGP-EVPN (Multi-Site).

Frequently Asked Questions
