Three of the 291 questions in this pack

Question 1

A vPC Type-1 inconsistency between two vPC peers in a VXLAN EVPN setup is discovered. Which two actions need to be attempted to resolve the issue? (Choose two.)

  1. Configure the NVE interfaces to be Up on both switches.
  2. Set a different distributed gateway virtual MAC address.
  3. Set a different secondary IP addresses on NVE source-interface.
  4. Configure the same VNI to multicast group maping.
  5. Set a different primary IP addresses on NVE source-interface.
Show answer and explanation

Correct answer: A, D. Configure the NVE interfaces to be Up on both switches; Configure the same VNI to multicast group maping.

vPC Type-1 inconsistencies in VXLAN EVPN occur when critical parameters differ between peers. Option A addresses NVE interface state, which must be operational for overlay traffic. Option D ensures that VNI-to-multicast group mappings are identical across peers, preventing BUM (broadcast, unknown unicast, multicast) traffic replication issues. These two elements are fundamental to maintaining vPC consistency in an EVPN fabric.

Why the other options are wrong

  • B. Distributed gateway virtual MAC addresses should be the same, not different, between vPC peers.
  • C. Secondary IP addresses on NVE source-interface are not a vPC Type-1 consistency requirement.
  • E. Primary IP addresses on NVE source-interface should be the same between peers, not different.

Question 2

A mission-critical server is connected to site A. Connectivity to this server is lost from site B because the MAC route is missing in the OTV VDC of the Cisco Nexus 7000 in site B due to MAC aging. Which action allows the flooding of the unknown unicast MAC on the Nexus 7000 in the OTV VDC?

  1. Use route map to statically advertise this MAC and redistribute with ISIS.
  2. Unknown unicast flooding is not allowed.
  3. Use the otv flood mac <> command to selectively flood traffic for a given MAC.
  4. Use the otv isis bfd <> command to configure BFD protocol.
Show answer and explanation

Correct answer: C. Use the otv flood mac <> command to selectively flood traffic for a given MAC.

The `otv flood mac` command allows selective MAC flooding on OTV edge devices, enabling specific MAC addresses to be flooded across the OTV overlay when normal MAC learning mechanisms fail due to aging or other reasons. This directly solves the problem of missing MAC routes by ensuring the critical server's MAC is reachable even if it has aged out of the local MAC table.

Why the other options are wrong

  • A. Static MAC advertisement via route maps and ISIS redistribution is not the standard method for OTV MAC flooding.
  • B. Unknown unicast flooding is absolutely allowed and configurable in OTV deployments.
  • D. BFD configuration does not address MAC flooding; it only monitors OTV overlay adjacency health.

Question 3

The Cisco Nexus switch is connected to a peer switch that is not running Cisco NX-OS. The switches are connected using port channel and are experiencing packet loss. Which action should be performed on the Cisco Nexus switch ports to resolve this issue?

  1. Turn on lacp suspend-individual.
  2. Turn on lacp graceful-convergence.
  3. Turn off lacp graceful-convergence.
  4. Turn off lacp suspend-individual.
Show answer and explanation

Correct answer: C. Turn off lacp graceful-convergence.

When a Cisco Nexus switch connects to a non-Cisco peer over port channel, packet loss can occur due to graceful convergence behavior waiting for protocol handshakes. Disabling `lacp graceful-convergence` allows the port channel to converge immediately without waiting for LACP negotiation completion, preventing packet loss during failover scenarios with non-standard LACP implementations.

Why the other options are wrong

  • A. Turning on `lacp suspend-individual` does not resolve packet loss with non-Cisco peers.
  • B. Graceful convergence is enabled by default and is the source of the problem.
  • D. The `lacp suspend-individual` setting is not the relevant parameter for this inter-vendor compatibility issue.

What makes the DCIT hard

DCIT is the exam that shows you outputs and asks what broke. Every objective in the v1.2 blueprint starts with the word troubleshoot, so the question style is a symptom, a show command or a log, and four plausible causes. It rewards people who have spent time on real incidents across Nexus, UCS and MDS rather than people who simply know the features.

Network and compute are 25% each. Network covers OSPFv2 and v3, MP-BGP, PIM and FHRPs, RSTP, LACP and vPC, VXLAN EVPN overlays, and ACI fabric discovery and forwarding. Compute covers UCS rack servers and blade chassis, SAN connectivity with zoning and VSANs, server pools and boot policies, and VIC adapters. Storage is Fibre Channel: fabric initialisation, buffer credit starvation, NPV and NPIV, and zoning. Automation covers EEM, the scheduler, REST API, Python, Ansible, Terraform and Intersight. Management and operations at 20% adds firmware upgrade failures, port security, AAA and RBAC, and ACI security domains.

About the exam

300-615 (Troubleshooting Cisco Data Center Infrastructure v1.2, DCIT) earns the Cisco Certified Specialist, Data Center Operations certification and counts as the concentration exam for CCNP Data Center. It covers troubleshooting data centre networking including ACI and VXLAN EVPN, UCS compute platforms, Fibre Channel storage networks, automation and programmability, and management, operations and security. No prerequisites.
