Question 1 Domain 3 SONiC Configuration

What two methods can be used to upgrade or downgrade Enterprise SONiC?

Correct Answer A, D
Explanation

Enterprise SONiC can be upgraded or downgraded using:

Boot Loader (A): The boot loader can be used to select and load different versions of the SONiC firmware.

GRUB (D): GRUB (Grand Unified Bootloader) is another method used to manage and select different SONiC firmware versions during system boot-up.

Question 2 Domain 1 SONiC Bundles

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

Correct Answer C
Explanation

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 3 Domain 4 Routing

Which two things does the no vrrp 100 address-family ipv6 command delete?

Correct Answer A, D
Explanation

The no vrrp 100 address-family ipv6 command deletes the VRRP (Virtual Router Redundancy Protocol) identifier (A) and the address-family configuration (D) for VRRP group 100. This effectively removes the VRRP configuration for the specified address family.

Question 4 Domain 3 SONiC Configuration

What is an iBGP neighbor relationship?

Correct Answer A
Explanation

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.

Question 5 Domain 2 SONiC Installation

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

Correct Answer D
Explanation

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 6 Domain 5 VXLAN

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.

Question 6 exhibit

Correct Answer A
Explanation

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.

These steps provide a comprehensive guide to configure a VRF and a static route within that VRF on a SONiC-based switch, ensuring the specific requirements for routing and administrative distance are met.

Question 7 Domain 3 SONiC Configuration

What is ECMP?

Correct Answer A
Explanation

ECMP (Equal-Cost Multi-Path) is a Layer 3 routing feature that allows traffic to be forwarded using multiple available paths of equal cost. This improves bandwidth utilization and provides redundancy. ECMP is commonly used in modern networks to optimize the flow of traffic and increase the resiliency of network connections.

FAQ

D-SNC-DY-00 Exam FAQ

Common questions about the exam itself

What experience level does the D-SNC-DY-00 exam assume I have?
The exam targets intermediate professionals who deploy and maintain Enterprise SONiC networks. Dell requires hands-on product experience or completion of their recommended training courses before sitting the exam. You need solid working knowledge of networking fundamentals and some real-world experience with SONiC or similar distribution platforms.
Is the D-SNC-DY-00 exam harder than other Dell networking certifications?
Yes, it covers substantial depth across six major domains including advanced topics like VXLAN, BGP EVPN, and MC-LAG. The SONiC Configuration domain alone accounts for 40 percent of test weight and requires practical hands-on understanding rather than just theory.
Which domain in D-SNC-DY-00 gives candidates the most trouble?
Routing and SONiC Configuration together make up 64 percent of the exam, and most candidates struggle with the Routing domain because it demands understanding of BGP operations, OSPF topology, and Equal Cost Multi-Pathing. Start with foundational routing concepts and build toward BGP configuration and redistribution.
How long should I plan to study for D-SNC-DY-00?
Most candidates need four to six weeks of consistent study if they already have networking experience, or two to three months if they are new to SONiC. Dell's recommended training courses provide structured learning, and hands-on lab experience is essential to move from theory to practical competence.
What is the format of the D-SNC-DY-00 exam on test day?
You get 120 minutes to complete the exam through an online proctored session using a Dell exam voucher. The exam uses multiple-choice and scenario-based questions that test practical problem-solving in real SONiC deployment situations.
Can I retake the D-SNC-DY-00 exam if I fail?
Yes, you can retake the exam, but Dell typically imposes a waiting period between attempts. Consult Dell's retake policy on their Proven Professional website, as policies may vary by region and can change.
How long is the Dell SONiC Deploy certification valid?
Dell does not publicly state a fixed validity period for this certification on their learning platform. Check the Proven Professional website or contact Dell directly for current certification maintenance and renewal requirements.
What job role does the D-SNC-DY-00 certification prepare me for?
The certification is designed for Implementation Specialists, Storage Implementation Engineers, and Systems Engineers who deploy SONiC networks. It validates your ability to configure, maintain, and troubleshoot Enterprise SONiC Distribution systems in production environments.
How does D-SNC-DY-00 relate to other Dell networking exams?
The SONiC Deploy exam stands alone as the qualifying exam for the Dell SONiC Deploy Certification and focuses specifically on SONiC platform expertise. It is distinct from other Dell infrastructure and storage certifications but complements broader Dell Proven Professional credentials.
What VXLAN topics should I focus on for D-SNC-DY-00?
VXLAN makes up 16 percent of the exam and requires you to understand both Asymmetric and Symmetric IRB architectures. Pay close attention to configuring and verifying BGP EVPN with both IRB types, as these are central to modern SONiC data center deployments.
