D-SNC-DY-00 Exam Syllabus & Core Topics

Use this topic map to guide your study for Dell EMC D-SNC-DY-00 (Dell SONiC Deploy Exam) within the SONiC Deploy path.

  • SONiC Bundles: Understand the composition and purpose of SONiC software bundles, including version management and compatibility requirements for different hardware platforms.
  • SONiC Installation: Master the installation process from image preparation through bootloader configuration, including troubleshooting common deployment issues.
  • SONiC Configuration: Configure core system settings, interfaces, and network parameters using both CLI and configuration file methods in production scenarios.
  • Routing: Design and implement static and dynamic routing protocols, including BGP and OSPF, to ensure optimal traffic flow across network segments.
  • VXLAN: Deploy VXLAN overlays for data center networking, configure VTEP endpoints, and manage multicast or unicast flood lists in multi-tenant environments.
  • QoS: Apply quality of service policies to prioritize traffic, manage bandwidth allocation, and meet service level requirements across different application types.

Question Formats & What They Test

The D-SNC-DY-00 exam combines multiple question types to assess both foundational knowledge and applied decision-making in real-world SONiC deployment scenarios.

  • Multiple Choice: Test recall of SONiC architecture, feature definitions, protocol behaviors, and configuration best practices.
  • Scenario-Based Items: Present multi-step deployment or troubleshooting situations where you select the most appropriate solution based on business requirements and technical constraints.
  • Configuration Thinking: Require you to identify correct CLI commands, parameter values, or configuration file syntax for specific network topologies and use cases.

Questions progress in difficulty and emphasize practical application, ensuring candidates can handle real production environments after passing.

Preparation Guidance

Effective preparation combines structured topic review with hands-on practice and realistic mock exams. Allocate study time proportionally to exam weight, and reinforce learning by connecting concepts across installation, configuration, and operational workflows.

  • Map SONiC Bundles, SONiC Installation, SONiC Configuration, Routing, VXLAN, and QoS to weekly study goals; track progress and adjust pace as needed.
  • Work through practice question sets and review detailed explanations to identify knowledge gaps and clarify misconceptions.
  • Link features and concepts across deployment, runtime configuration, and troubleshooting to build a complete mental model.
  • Complete a timed mini mock exam to practice pacing, reduce test anxiety, and simulate exam conditions.
  • In the final week, focus on weak topic areas and review high-level workflows rather than memorizing isolated facts.

Frequently Asked Questions

Which topics carry the most weight on the D-SNC-DY-00 exam?

SONiC Configuration and Routing typically account for the largest portion of exam questions, as they form the foundation of practical deployment work. However, all six topics are essential; even lighter-weighted sections like QoS can include scenario-based questions that test your ability to integrate multiple concepts in real environments.

How do SONiC Installation and SONiC Configuration connect in real project workflows?

Installation establishes the base operating system and bootloader, while Configuration applies network policies, routing rules, and interface settings on top. In practice, you must first successfully deploy the correct SONiC bundle version, then immediately configure it for your specific network topology, making both skills interdependent and equally critical.

How much hands-on lab experience helps, and which areas should I prioritize?

Hands-on experience is highly beneficial because SONiC configuration involves CLI syntax and parameter values that are difficult to memorize from text alone. Prioritize labs covering SONiC Installation, basic interface configuration, and BGP or OSPF routing setup, as these appear frequently in exam questions and build confidence in command-line navigation.

What common mistakes lead to lost points on this exam?

Candidates often confuse VXLAN flood list modes (multicast versus unicast), overlook QoS configuration order and priority, or misunderstand bundle compatibility requirements across hardware platforms. Another frequent error is selecting a routing solution without considering the network topology or convergence requirements described in the scenario.

What is an effective pacing and review strategy for the final week before the exam?

In your final week, spend 60% of time on weak topic areas identified in practice tests and 40% reviewing high-level workflows and decision trees. Avoid deep dives into new material; instead, do quick refresher reads and one final timed practice test to build confidence and catch any remaining gaps before exam day.

Question No. 1

SIMULATION

Configure a VRF called "VrfGreen" and the static route in it to network 172.16.128.64/28 through next-hop 10.10.10.1. Set an administrative distance of 213.

Show Answer Hide Answer
Correct Answer: A

Here are the steps to configure the VRF and the static route:

Enter Configuration Mode:

sonic# configure terminal

Create VRF 'VrfGreen':

sonic(config)# ip vrf VrfGreen

Configure the Static Route:

sonic(config)# ip route vrf VrfGreen 172.16.128.64/28 10.10.10.1 213

Save Configuration:

sonic# write memory

Comprehensive Detailed Step by Step Explanation with Reference:

Enter Configuration Mode:

Begin by entering the global configuration mode to make changes to the switch configuration.

Create VRF 'VrfGreen':

Use the command ip vrf VrfGreen to create a new VRF named 'VrfGreen'. This command sets up a new VRF instance which will isolate the routing table for this VRF from the global routing table and other VRFs.

Configure the Static Route:

Use the command ip route vrf VrfGreen 172.16.128.64/28 10.10.10.1 213 to configure the static route.

ip route vrf VrfGreen specifies that the route should be added to the 'VrfGreen' VRF.

172.16.128.64/28 is the destination network.

10.10.10.1 is the next-hop IP address.

213 is the administrative distance, which in this case is set to a non-default value to influence route preference.

Save Configuration:

Save the configuration to ensure the changes persist after a reboot using the write memory command.

Question No. 3

How many port channels can be assigned to a single port?

Show Answer Hide Answer
Correct Answer: D

According to the Dell SONiC documentation, a single physical port can be a member of only one port channel at a time. This restriction ensures the consistency and integrity of link aggregation configurations.

Question No. 4

How many times must BGP be configured when running symmetric IRB with two VFRs?

Show Answer Hide Answer
Correct Answer: C

When running symmetric Integrated Routing and Bridging (IRB) with two Virtual Forwarding Routers (VFRs), BGP must be configured twice. Each VFR will have its own BGP instance to handle the routing information.

Question No. 5

What is an iBGP neighbor relationship?

Show Answer Hide Answer
Correct Answer: A

An iBGP (Internal Border Gateway Protocol) neighbor relationship is established between two BGP routers within the same autonomous system (AS). This relationship allows for the exchange of routing information within the AS, ensuring that internal routes are propagated correctly.
