Sample Cisco DCCOR (350-601) Practice Questions

Try these sample questions to test your Cisco DCCOR (350-601) exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1On a pair of Cisco Nexus 9000 switches, which link is required between the two peers BEFORE the vPC peer-link can come up?
A.The peer-keepalive link
B.The orphan-port link
C.An OSPF backbone adjacency
D.A FabricPath core port
Explanation: The peer-keepalive link must be operational before NX-OS will bring up the vPC peer-link. Keepalive runs as a Layer 3 heartbeat, typically over the management VRF or a dedicated VRF, and is used to detect a dual-active condition if the peer-link fails.
2What is the DEFAULT vPC role priority on a Cisco Nexus switch, and which peer becomes the vPC primary?
A.Default 1; lowest priority becomes primary
B.Default 32667; lowest priority becomes primary
C.Default 32768; highest priority becomes primary
D.Default 100; highest priority becomes primary
Explanation: The default vPC role priority is 32667. The switch with the LOWEST role priority becomes the vPC primary; if priorities tie, the switch with the lower system MAC wins. Role priority does not preempt by default — a reload is required for a new primary to take over.
3Which statement BEST describes a vPC Type-1 consistency check failure?
A.Only newly added ports are suspended; existing vPCs continue to forward
B.All vPC member ports on the secondary peer are suspended
C.The peer-link is reset and renegotiated
D.Only the orphan ports are shut down
Explanation: Type-1 (global) consistency parameters include things like STP mode, MST region, and vPC domain ID. A Type-1 mismatch is considered fatal: the secondary peer suspends ALL of its vPC member ports until the mismatch is corrected. Type-2 mismatches generate warnings but keep traffic forwarding.
4Which OSPF area type allows external Type-7 LSAs originated within the area but blocks Type-5 LSAs from outside?
A.Stub area
B.Totally stubby area
C.Not-so-stubby area (NSSA)
D.Backbone area
Explanation: An NSSA permits an ASBR inside the area to redistribute external routes as Type-7 LSAs, which the ABR then translates to Type-5 when leaving the area. Standard Type-5 LSAs from other ASBRs outside the NSSA are blocked from entering it.
5In a VXLAN EVPN fabric, which BGP EVPN route type carries host MAC and IP reachability between VTEPs?
A.Type 1 — Ethernet Auto-Discovery
B.Type 2 — MAC/IP advertisement
C.Type 3 — Inclusive Multicast Ethernet Tag
D.Type 5 — IP Prefix
Explanation: EVPN Route Type 2 advertises a host MAC address and optionally its IP address (and the L2VNI/L3VNI labels) so remote VTEPs can install both the MAC for L2 forwarding and the host route for L3 (silent host) forwarding via integrated routing and bridging.
6A VXLAN EVPN fabric uses ingress replication for BUM traffic. Which EVPN route type signals the list of VTEPs that should receive a copy of BUM traffic for an L2VNI?
A.Type 1
B.Type 2
C.Type 3
D.Type 4
Explanation: Inclusive Multicast Ethernet Tag (Type 3) routes are advertised by every VTEP that is interested in a given L2VNI. With ingress replication, each VTEP uses the Type 3 list as its replication target list for broadcast, unknown-unicast, and multicast frames.
7In a Cisco ACI fabric, which controller component MAINTAINS the policy and configuration database that is then pushed to leaf and spine switches?
A.Nexus Dashboard Fabric Controller (NDFC)
B.APIC cluster
C.vCenter VMM domain
D.Nexus Insights
Explanation: The Application Policy Infrastructure Controller (APIC) cluster is the single point of policy and management for an ACI fabric. APICs (typically a 3+ node cluster for production) hold the policy model and program leaf/spine switches, but data-plane forwarding does not depend on the APICs being online.
8Which ACI object groups endpoints that share the same security policy regardless of subnet or VLAN?
A.Bridge Domain (BD)
B.VRF
C.Endpoint Group (EPG)
D.Tenant
Explanation: An EPG is the ACI policy primitive that groups endpoints with the same security and forwarding requirements. Communication between EPGs requires a contract (provider/consumer); endpoints inside an EPG can communicate freely unless intra-EPG isolation or microsegmentation is configured.
9An ACI tenant needs external Layer 3 connectivity to a WAN router running OSPF. Which ACI construct should be configured?
A.L2Out
B.L3Out
C.vzAny
D.uSeg EPG
Explanation: An L3Out (External Routed Network) under a VRF defines the routing protocol (OSPF, BGP, EIGRP, static), the border-leaf interface, and the External EPG used to apply contracts to external prefixes. It is the standard way to peer ACI with external L3 networks.
10Which ACI feature lets every EPG in a VRF communicate freely while still allowing contract enforcement against EPGs outside the group?
A.vzAny
B.Preferred Group
C.Contract Inheritance
D.Intra-EPG Isolation
Explanation: Preferred Group is a VRF-level setting where any EPG marked as a member of the preferred group can communicate freely with all other preferred-group EPGs without contracts. Communication outside the group still requires contracts.

Cisco DCCOR (350-601) Study Tips from Top Performers

1Memorize the EVPN route types: Type 2 = MAC/IP host advertisement, Type 3 = Inclusive Multicast for BUM, Type 5 = IP Prefix — these come up repeatedly in DCCOR scenarios
2Drill vPC details: peer-keepalive must be up before peer-link, default role priority is 32667, lowest priority becomes primary, and Type-1 consistency mismatches suspend ALL vPC ports on the secondary
3Build a mental map of UCS service profile vs template (Initial vs Updating), pool types (MAC, UUID, WWNN, WWPN, server), and policies (boot, BIOS, maintenance, host firmware) — UCS has the most named objects on the exam
4Learn the Fibre Channel port-type letters cold (E_Port between switches, F_Port to host F-side, N_Port on the host, NP_Port for NPV uplinks) and the FLOGI -> PLOGI -> PRLI sequence
5Practice the difference between NPV (edge) and NPIV (core) plus when you would enable each, and remember smart zoning trims TCAM by skipping initiator-to-initiator entries
6Know the automation tools by API target: cisco.nxos for NX-OS, cisco.aci for APIC, cisco.ucs for UCS Manager, cisco.intersight for Intersight, plus EEM/Scheduler/POAP for on-box automation
