Dell EMC D-SNC-DY-00 Exam Questions
- Topic 1: SONiC Bundles: In this topic, your understanding of Enterprise SONiC bundles will be assessed. As a cloud engineer, you must be able to compare different SONiC bundles, demonstrating your expertise in selecting the appropriate bundle for various cloud environments. Mastery of this will ensure you can optimize network configurations effectively.
- Topic 2: SONiC Installation: Your proficiency in SONiC installation, upgrade, and downgrade methods will be tested in this Dell EMC D-SNC-DY-00 exam topic. You will need to install SONiC using both the ONIE manual and automatic methods. This topic measures your hands-on skills in managing SONiC installations efficiently.
- Topic 3: SONiC Configuration: This comprehensive topic evaluates your ability to administer and configure critical network components. You will need to manage port groups, configure management access, handle VLANs, and verify advanced features like Link Aggregation Groups and MC-LAG. Proficiency in these Dell EMC D-SNC-DY-00 exam areas is crucial for ensuring robust and scalable network operations.
- Topic 4: Routing: Here, your routing knowledge will be tested, particularly in administering L3 IP addressing, configuring static routes, and understanding OSPF and BGP operations. As a cloud engineer, you must be adept at managing routing protocols and configurations to maintain efficient network traffic flow.
- Topic 5: VXLAN: This topic focuses on your ability to manage VXLAN operations, including configuring and verifying BGP EVPN with both Asymmetric and Symmetric IRB. Understanding VXLAN is essential for enabling scalable and efficient cloud networks, making this topic critical to your D-SNC-DY-00 exam success.
- Topic 6: QoS: Your understanding of Quality of Service (QoS) is essential to become a certified Dell cloud engineer. The exam evaluates your ability to configure and verify QoS features. This section tests your ability to ensure optimal network performance, a vital skill in managing cloud environments where service quality is paramount.

Enterprise SONiC Switch 1 and Switch 2 are part of a symmetric VXLAN fabric in a data center environment. Switch 1 has learned MAC addresses from its local VLANs.
What role does BGP EVPN play in this scenario?
BGP EVPN (Border Gateway Protocol Ethernet VPN) is used in a VXLAN fabric to distribute MAC address reachability information between switches. In this scenario, Switch 1 uses BGP EVPN to advertise the locally learned MAC addresses to Switch 2. This distribution of MAC addresses enables the switches to build and maintain an efficient forwarding table, facilitating communication across the VXLAN fabric.

Refer to the exhibit.
What can be determined from this show command?
The output of the command show qos wred-policy pfc34 shows the ECN (Explicit Congestion Notification) configuration for the policy pfc34. The line ecn: ecn_all indicates that ECN is enabled for all traffic classes (all DSCP values). Additionally, the green-min-threshold, green-max-threshold, and green-drop-probability settings are shown, but there is no indication of a 10% probability for marking traffic as congested. Therefore, the correct answer is B.

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?
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.

Which two additional Q-in-Q VLAN tunnel configuration steps must be followed if the provider network uses a VXLAN overlay?
Configure VLAN Translation (A): VLAN translation is necessary to translate customer VLANs (CVLANs) to service VLANs (SVLANs) for Q-in-Q tunneling in a VXLAN environment.
Map the SVLAN traffic to a VNI (B): SVLAN traffic must be mapped to a VXLAN Network Identifier (VNI) for encapsulation and transport across the VXLAN overlay network.

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