Exam Objectives
Here is a high-level view of the skillset required to successfully complete the JNCIE-DC certification exam.
Layer 3 Underlay
In a controllerless data center, a successful candidate will:
• Build, deploy, and troubleshoot an IP fabric
• Use routing policies to ensure that only required addresses are advertised
• Use all available links for forwarding traffic
In a data center managed by Juniper® Apstra software, a successful candidate will:
• Build, deploy, and troubleshoot an IP fabric
• Use routing policies to ensure that only required addresses are advertised
• Create and use custom tags
• Restrict all fabric device configurations to Apstra
• Use all available links for forwarding traffic
Overlay
In a controllerless data center, a successful candidate will:
• Deploy, manage, and troubleshoot an EBGP- or IBGPsignaled EVPN-VXLAN overlay
• Establish communication between multihomed and singlehomed end devices
• Create multiple separate Layer 2 and Layer 3 tenant environments
• Enable routing between different Layer 3 tenants
• Configure and optimize multicast communication In a data center managed by Apstra, a successful candidate will:
• Deploy, manage, and troubleshoot an EBGP-signaled EVPNVXLAN overlay
• Establish communication between multihomed and singlehomed end devices
• Create multiple separate Layer 3 tenant environments
• Enable routing between different Layer 3 tenants
Data Center Interconnect (DCI)
A successful candidate will:
• Deploy, manage, and troubleshoot a DCI solution between a Juniper Apstra-managed data center and a controllerless data center using Type 2 or Type 5 EVPN routes to enable tenant communication between data centers without the use of Apstra configlets
• Deploy, manage, and troubleshoot a DCI solution between two controllerless data centers using seamless VXLAN-toVXLAN stitching to enable tenant communication between data centers
• Identify incoming VXLAN virtual network identifier (VNI) information from an unmanaged preconfigured peer device
Security
A successful candidate will:
• Deploy, manage, and troubleshoot security features that protect the data center infrastructure and edge devices
• Restrict device access from unauthorized protocols and networks
• Monitor and log excessive traffic events
• Monitor and track various spanning-tree messages and take required actions according to the defined security
requirements
Class of Service (CoS)
A successful candidate will:
• Configure and troubleshoot CoS settings for server traffic connected to leaf nodes
Management
A successful candidate will:
• Use tags and probes to track critical services and trigger Apstra anomalies when specific conditions are met or
exceeded
• Create and use custom Apstra configlets
• Enable subsecond link failure detection using Bidirectional Forwarding Detection (BFD) between leaf and external devices
• Implement date and time synchronization for devices
• Configure local and remote system logging
• Enable streaming telemetry on custom ports
• Use SNMP monitoring in the data centers
