Data Center, Expert (JNCIE-DC)

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 IBGP- signaled EVPN-VXLAN overlay
• Establish communication between multihomed and single- homed 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 EVPN- VXLAN overlay
• Establish communication between multihomed and single-homed end devices
• Create multiple separate Layer 3 tenant environments
• Enable routing between different Layer 3 tenants

Date 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-to-VXLAN stitching to enable tenant communication between data centers
• Identify incoming VXLAN virtual network identifier (VNI) information from an unmanaged preconfigured peer devices

Security

A successful candidate will:

• Deploy, manage, and troubleshoot security features that protect the data center infrastructure and edge device
• 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
