Question 1 Domain 2SONiC Installation

Refer to the exhibit.

Eth 1/1 of SONiC-1 and Eth1/56 of SONiC-2 should be a routed link connecting the two Enterprise SONiC switches. No traffic is passing between them.

What is the cause of the failure?

Correct Answer: A
Explanation

From the exhibit, it is evident that Eth1/56 on SONiC-2 is assigned a link-local IPv6 address (fe80::e7d:8aff:fecb

/64). Link-local addresses are not routable beyond the local network segment, which means they cannot be used to route traffic between SONiC-1 and SONiC-2. For routed links, global unicast addresses must be used.

Question 2 Domain 2SONiC Installation

An administrator is installing Enterprise SONIC in ONIE from an HTTP server.

On which interface should the administrator configure the IP?

Correct Answer: C
Explanation

When installing Enterprise SONIC from an HTTP server using the Open Network Install Environment (ONIE), the management interface typically used for network installations is eth0. This is the default interface ONIE uses for network connectivity to retrieve installation images and other configuration files.

Question 3 Domain 5VXLAN

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.

Question 4 Domain 3SONiC Configuration

An administrator obtains the following CLI output:

How much time does the local system take to detect remote failures without receiving packets?

Correct Answer: B
Explanation

The local timers in the BFD (Bidirectional Forwarding Detection) configuration show a detect multiplier of 4 and a receive interval of 300ms. The time taken to detect remote failures is calculated as detect multiplier receive interval = 4 300ms = 1200ms.

Question 5 Domain 4Routing

SIMULATION

Create port channel 10 on interfaces Eth 1/11 and 1/12, so that it connects to an already configured switch. A server will be connected on Eth 1/1. Both the server and port channel need VLAN 1 untagged and only VLAN 10 tagged.

Complete the configuration on Switch A.

Correct Answer: A
Explanation

Here are the steps to configure the required port channel and VLAN settings on Switch A:

Enter Configuration Mode:

SwitchA# configure terminal

Create Port Channel 10:

SwitchA(config)# interface port-channel 10

SwitchA(config-if-po10)# switchport mode trunk

SwitchA(config-if-po10)# switchport trunk native vlan 1

SwitchA(config-if-po10)# switchport trunk allowed vlan 1,10

Assign Interfaces Eth 1/11 and Eth 1/12 to Port Channel 10:

SwitchA(config)# interface ethernet 1/11

SwitchA(config-if-eth1/11)# channel-group 10 mode active

SwitchA(config-if-eth1/11)# exit

SwitchA(config)# interface ethernet 1/12

SwitchA(config-if-eth1/12)# channel-group 10 mode active

SwitchA(config-if-eth1/12)# exit

Configure Interface Eth 1/1 for Server Connection:

SwitchA(config)# interface ethernet 1/1

SwitchA(config-if-eth1/1)# switchport mode trunk

SwitchA(config-if-eth1/1)# switchport trunk native vlan 1

SwitchA(config-if-eth1/1)# switchport trunk allowed vlan 1,10

SwitchA(config-if-eth1/1)# end

Save Configuration:

SwitchA# write memory

Comprehensive Detailed Step by Step Explanation with Reference:

Enter Configuration Mode:

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

Create Port Channel 10:

Enter the port channel interface configuration mode using interface port-channel 10.

Set the port channel to trunk mode with switchport mode trunk.

Specify VLAN 1 as the native VLAN (untagged) using switchport trunk native vlan 1.

Allow VLANs 1 and 10 on the trunk with switchport trunk allowed vlan 1,10.

Assign Interfaces Eth 1/11 and Eth 1/12 to Port Channel 10:

Enter interface configuration mode for ethernet 1/11 and ethernet 1/12.

Assign each interface to port channel 10 using the channel-group 10 mode active command.

Exit the interface configuration mode.

Configure Interface Eth 1/1 for Server Connection:

Enter interface configuration mode for ethernet 1/1.

Set the interface to trunk mode with switchport mode trunk.

Specify VLAN 1 as the native VLAN using switchport trunk native vlan 1.

Allow VLANs 1 and 10 on the trunk with switchport trunk allowed vlan 1,10.

Exit the configuration mode.

Save Configuration:

Ensure the configuration is saved so it persists after a reboot using the write memory command.

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.
