1An engineer is troubleshooting an OSPFv2 adjacency that is stuck in EXSTART/EXCHANGE on a Nexus 9000. Which mismatch most commonly causes this state?
A.Authentication key mismatch
B.Hello/Dead timer mismatch
C.MTU mismatch on the segment
D.Different OSPF process IDs
Explanation: When neighbors reach EXSTART/EXCHANGE, they have already agreed on Hello/Dead timers, area, and authentication. They negotiate master/slave and exchange DBD packets. If interface MTUs differ, DBD packets cannot be processed and the adjacency stalls in EXSTART or EXCHANGE. Either fix the MTU or use the ip ospf mtu-ignore command on the interface.
2Which NX-OS command displays the OSPFv2 neighbor state machine progression for all neighbors on a Nexus switch?
A.show ip ospf neighbor detail
B.show ip ospf database
C.show ip route ospf
D.show running-config ospf
Explanation: show ip ospf neighbor detail lists each OSPF neighbor with its current state (DOWN, INIT, 2WAY, EXSTART, EXCHANGE, LOADING, FULL), router ID, dead time, address, and DR/BDR role. It is the first command for OSPF adjacency troubleshooting.
3A vPC peer-link is up but the secondary peer suspends all vPC member ports. Which condition most likely triggered this behavior?
A.vPC peer-keepalive link is down
B.Type-1 global inconsistency (e.g., STP mode mismatch)
C.Different vPC role-priority values
D.vPC domain ID mismatch
Explanation: Type-1 global inconsistencies (STP mode, MST region, LACP system MAC for vPC, etc.) cause both vPCs and the peer-link to suspend all vPC member ports on the secondary so traffic does not loop or black-hole. show vpc consistency-parameters global highlights the mismatch.
4Which command verifies that the vPC peer-keepalive is alive between two Nexus peers?
A.show vpc role
B.show vpc peer-keepalive
C.show vpc consistency-parameters global
D.show port-channel summary
Explanation: show vpc peer-keepalive displays the keepalive status, source and destination IP, VRF, and the time of the last received message. The keepalive does not pass data; it detects peer failure to prevent dual-active when the peer-link goes down.
5An MP-BGP EVPN session between two VTEPs is stuck in Active state. Which check is most useful first?
A.Verify NVE source-interface IP reachability via the underlay
B.Confirm L2VPN EVPN address-family is activated under the neighbor
C.Check that ingress replication is configured on every VLAN
D.Validate spanning-tree mode matches between VTEPs
Explanation: BGP stuck in Active typically means the TCP session never established or the neighbor is not configured for the desired address-family. For EVPN, you must explicitly enable the L2VPN EVPN address-family under each neighbor (address-family l2vpn evpn / send-community extended). Underlay reachability is also required, but the most common EVPN-specific cause is forgetting to activate the AFI on the neighbor.
6Which NX-OS command lists all locally and remotely learned MAC addresses for VXLAN EVPN, including the next-hop VTEP?
A.show mac address-table
B.show l2route mac all
C.show bgp ipv4 unicast
D.show nve interface
Explanation: show l2route mac all is the EVPN control-plane view: it lists every MAC the switch knows from BGP EVPN and the local bridge domain, along with the producer (BGP vs Local), VNI, and next-hop VTEP IP. It is essential for verifying EVPN MAC propagation.
7When using PIM ASM with a static RP, which command verifies which RP a Nexus switch is using for a multicast group?
A.show ip pim rp
B.show ip mroute summary
C.show ip igmp groups
D.show ip pim interface
Explanation: show ip pim rp lists the RP-to-group mappings the device is using, the RP source (static, BSR, or Auto-RP), and the originating router. This is the starting point when PIM (*,G) trees fail to form.
8BUM traffic in a VXLAN EVPN fabric without a multicast underlay is forwarded using which mechanism?
A.Source-specific multicast (SSM)
B.Bidirectional PIM (BIDIR-PIM)
C.Ingress replication via BGP EVPN type-3 routes
D.Anycast-RP via MSDP
Explanation: Without a multicast-capable underlay, BUM (broadcast, unknown unicast, multicast) traffic is delivered using ingress replication. Each VTEP advertises its membership for a VNI through a BGP EVPN type-3 (Inclusive Multicast Ethernet Tag) route, and the source VTEP unicast-encapsulates BUM frames to every remote VTEP listed.
9A leaf switch in an ACI fabric is stuck in the DISCOVERING state and never reaches REGISTERED. Which check is most relevant?
A.Verify the APIC has the leaf's serial number registered with a node ID
B.Confirm BGP route reflectors are configured under fabric policies
C.Validate the leaf's TEP pool overlaps with the spine TEP pool
D.Run acidiag fnvread on the leaf
Explanation: A leaf must be assigned a node ID and node name through the APIC fabric membership policy before it transitions from DISCOVERING to REGISTERED to ACTIVE. The leaf is identified to the APIC by its serial number; until the APIC registers the serial, the leaf will sit in DISCOVERING.
10Which ACI object directly defines which leaf interfaces are bundled into a vPC towards a downstream device?
A.VRF
B.Bridge Domain
C.Interface Policy Group of type vPC
D.Endpoint Group
Explanation: In ACI access policies, an Interface Policy Group of type vPC bundles two leaf-side ports across a vPC pair to form a single port-channel toward a downstream switch or server. The IPG is then attached to interfaces via Interface Profiles and Switch Profiles.

Cisco DCIT 300-615 Study Tips from Top Performers

1Spend equal time on Network and Compute Platforms (25% each) — they together carry 50% of the blueprint and are the heaviest troubleshooting domains.
2Memorize the OSPF state machine (DOWN, INIT, 2WAY, EXSTART, EXCHANGE, LOADING, FULL) and the canonical stuck-in-EXSTART = MTU mismatch symptom — this and other state-to-cause mappings are heavily tested.
3Master the vPC inconsistency model: Type-1 global (STP mode, system MAC) suspends vPCs, Type-1 LAN (VLAN-list at the peer-link) suspends per-VLAN, and Type-2 (MTU, speed) only logs warnings.
4Build a small VXLAN EVPN lab in Cisco Modeling Labs (CML) with two leaves and one spine, then practice show nve peers, show l2route mac all, show bgp l2vpn evpn, and ingress replication via type-3 routes.
5Drill UCS troubleshooting flows end-to-end: blade discovery via IOM, service profile association faults (F0157), maintenance policies (User Ack vs Immediate), and the recommended UCSM-then-IOM-then-FI-then-blade firmware upgrade order.
6For storage, practice show flogi database, show fcns database vsan <id>, show zone active, and zone-merge troubleshooting; understand BB_credit starvation symptoms and slow-drain mitigations on MDS.
7Get comfortable with NX-API and EEM applets — write a syslog-pattern applet and a small Python script in Guest Shell that calls NX-API CLI, then parse the ins_api.outputs.output.body JSON path.
