Dell EMC Dell SONiC Deploy D-SNC-DY-00 Exam Practice Test
Question 1
How many port channels can be assigned to a single port?
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 2
What are the supported modes for the QSFP28 ports on an S5248F?
Answer : A
The QSFP28 ports on an S5248F switch support multiple modes, including 1x100G, 1x40G, 2x50G, and 4x25G. These modes provide flexibility in network design and enable the switch to support different types of network connections and bandwidth requirements.

Question 3
Refer to the exhibit.
Which three actions can a customer take to change interface Eth1/10 to operate in access mode for VLAN 40?
Answer : A, D, E
Configure the access mode for the switch port (A): This involves setting the switch port to operate in access mode.
Remove the current access VLAN configuration (D): Before changing the VLAN, the current configuration must be cleared.
Enter it into the relevant interface (E): Apply the new configuration to the specific interface, Eth1/10.
Steps:
interface Ethernet 1/10
no switchport access vlan <current VLAN> (Remove current VLAN)
switchport mode access
switchport access vlan 40

Question 4
Refer to the exhibit.
What type of route is shown?
Answer : B
The exhibit shows a BGP EVPN route in a VXLAN environment. The route type can be determined based on the details provided. Type 2 routes in BGP EVPN are used to advertise MAC address reachability information between VTEPs (Virtual Tunnel End Points). The exhibit indicates a host route from another VTEP, which corresponds to a Type 2 route.

Question 5
What interface must be selected when configuring the management port from within the MF-CLI environment?
Answer : D
Dell SONiC Management Interface Configuration:
In Dell SONiC, the management port configuration is a crucial aspect that allows administrators to access and manage the network device.
The management interface typically provides out-of-band management access to the device, ensuring that even if the data network is down, the management network can still be accessed.
Common Interface Naming Conventions:
mgmt 1/1/1: This naming convention is not typically used in Dell SONiC environments for management interfaces.
ma 0/1: This could be a potential naming convention but is not standard for Dell SONiC.
Management 0: This is a logical name but does not align with the standard interface naming conventions used in Dell SONiC.
eth0: This is the standard naming convention used for the primary management interface in most Linux-based systems, including Dell SONiC.
Verification with Dell SONiC Documentation:
Dell SONiC documentation specifies that the management interface is usually named eth0.
When accessing the management interface within the MF-CLI (Management Framework Command Line Interface) environment, eth0 is the correct interface to configure.
Practical Configuration Example:
When configuring the management port, the command might look something like:
config interface ip add eth0 <management_ip_address>/<subnet_mask>
This command specifies the management interface eth0 and assigns it an IP address for network management purposes.

This detailed step-by-step explanation confirms that the correct answer is D, providing insights into the typical interface naming conventions and configuration practices within the Dell SONiC environment.
Question 6
Refer to the exhibit.
The route distinguisher was autogenerated. Which VLAN is mapped to VNI410?
Answer : C
The route distinguisher (RD) in the exhibit is 10.0.2.26:41. The RD typically reflects the VNI and VLAN mapping configuration. Given that the VNI is 410 and the RD ends with :41, it implies that VLAN 10 is mapped to VNI 410.

Question 7
Which two elements are configured when RoCE is enabled?
Answer : B, C
When RDMA over Converged Ethernet (RoCE) is enabled, Enhanced Transmission Selection (ETS) and Priority Flow Control (PFC) are two key elements that need to be configured. ETS allows for bandwidth allocation among different traffic classes, and PFC provides lossless Ethernet operation for specific traffic classes to support low-latency, high-performance network communication.
