1500 Questions | CCIE Data Center: The Complete Guide 2026

Detailed Exam Domain Coverage

To achieve the CCIE Data Center certification, you must demonstrate expert-level knowledge across these core domains. This practice test suite is designed to align perfectly with the official curriculum:

• DC Network Infrastructure (15%): Implementing DCNM for configuration management, FabricPath for Layer 3 switching, and vDSAN for virtualization environments.

• Storage Networking (12%): Mastering Fibre Channel, FCoE, iSCSI, and NVMe protocols alongside SAN and NAS system management.

• Data Center Networking (14%): Designing robust architectures, implementing VXLAN for Layer 2 transport, and configuring BFD for rapid convergence.

• Application and Automation Networking (22%): Automating infrastructure with Ansible and Python, managing CI/CD pipelines, and deploying service mesh architectures like Istio.

• Security (19%): Building comprehensive security frameworks, managing complex ACLs, and enforcing segmentation through network virtualization.

• Operations and Management (18%): Troubleshooting large-scale data center networks using both GUI and CLI while maintaining strict change control and documentation.

Course Description

I have meticulously engineered this CCIE Data Center practice exam course to be the final step in your certification journey. With 1,500 original, high-level questions, I provide the depth and technical rigor required to face the actual 250-question exam with absolute confidence.

Navigating the CCIE level requires more than just memorization; it requires a deep architectural understanding. That is why I have included exhaustive explanations for every single option in this bank. I break down the "why" behind the correct configurations and, perhaps more importantly, explain why certain distractors are incorrect in a data center context.

Sample Practice Questions

• Question 1: A network engineer is implementing a VXLAN EVPN fabric and needs to ensure rapid link failure detection for the underlying IGP. Which protocol should be configured to achieve sub-second convergence?

  • A. LACP (Link Aggregation Control Protocol)

  • B. BFD (Bidirectional Forwarding Detection)

  • C. VTP (VLAN Trunking Protocol)

  • D. PAgP (Port Aggregation Protocol)

  • E. MSTP (Multiple Spanning Tree Protocol)

  • F. HSRP (Hot Standby Router Protocol)

  • Correct Answer: B

  • Explanation:

    • B (Correct): BFD provides low-overhead, fast detection of failures in the forwarding path between two adjacent routers, essential for CCIE-level network convergence.

    • A (Incorrect): LACP manages link bundles but does not provide the sub-second path failure detection required for routing protocols.

    • C (Incorrect): VTP is for VLAN propagation and is generally avoided or used in transparent mode in modern DC fabrics.

    • D (Incorrect): PAgP is a Cisco-proprietary link aggregation protocol and does not handle IGP convergence.

    • E (Incorrect): MSTP handles loop prevention but is significantly slower than BFD for path failure detection in a VXLAN leaf-spine architecture.

    • F (Incorrect): HSRP is a first-hop redundancy protocol, not a mechanism for underlying IGP path liveness.

• Question 2: Which storage protocol allows for the transport of Fibre Channel frames over an Ethernet network while maintaining the lossless characteristics of a traditional SAN?

  • A. iSCSI

  • B. NVMe-oF (TCP)

  • C. NFS

  • D. FCoE (Fibre Channel over Ethernet)

  • E. SMB 3.0

  • F. HTTP/S

  • Correct Answer: D

  • Explanation:

    • D (Correct): FCoE encapsulates FC frames into Ethernet, requiring Priority Flow Control (PFC) to ensure the "lossless" fabric required by storage.

    • A (Incorrect): iSCSI runs over standard TCP/IP and does not encapsulate Fibre Channel frames directly.

    • B (Incorrect): While NVMe-oF is high-performance, FCoE is the specific protocol for carrying legacy FC frames over Ethernet.

    • C (Incorrect): NFS is a file-level NAS protocol, not a block-level SAN protocol.

    • E (Incorrect): SMB is a Windows-centric file sharing protocol.

    • F (Incorrect): HTTP/S is an application-layer protocol and not used for raw storage fabric transport.

• Question 3: When using Ansible to automate Cisco NX-OS devices, which module is primarily used to execute a specific list of configuration commands on the target device?

  • A. nxos_interface

  • B. nxos_vlan

  • C. nxos_config

  • D. nxos_facts

  • E. nxos_bgp

  • F. nxos_feature

  • Correct Answer: C

  • Explanation:

    • C (Correct): The nxos_config module is the versatile "catch-all" module for sending arbitrary configuration commands to an NX-OS device.

    • A (Incorrect): nxos_interface is specific to managing physical or logical interface attributes only.

    • B (Incorrect): nxos_vlan is scoped specifically to VLAN creation and management.

    • D (Incorrect): nxos_facts is used to collect information from the device, not to push configuration changes.

    • E (Incorrect): nxos_bgp is dedicated solely to BGP routing configurations.

    • F (Incorrect): nxos_feature is used to enable or disable NX-OS features (like feature ospf).
