Free Practice Questions for EMC D-SNC-DY-00 Exam

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 (Remove current VLAN)

switchport mode access

switchport access vlan 40

The static route shown in the exhibit S* 12.0.0.0/16 via 192.168.45.254 Vlan45 is used to provide a route to the 12.0.0.0 network. This static route directs traffic destined for the 12.0.0.0/16 network through the gateway at 192.168.45.254, which is associated with VLAN 45. This configuration is typically used to ensure that traffic can reach a specific network via a defined path.

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 /

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.

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.

IPv6 Addressing Guide

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.

Here are the steps to create the VTEP and map the VNI to the VLAN:

Enter Configuration Mode:

SwitchA# configure terminal

Create VTEP Interface:

SwitchA(config)# interface vtep1

SwitchA(config-if-vtep1)# ip address 10.10.10.1/24

SwitchA(config-if-vtep1)# exit

Map VNI 400 to VLAN 40:

SwitchA(config)# vlan 40

SwitchA(config-vlan)# vn-segment 400

SwitchA(config-vlan)# exit

Enable ARP Neighbor Suppression:

SwitchA(config)# interface Vlan40

SwitchA(config-if-Vlan40)# ip address 192.168.40.254/24

SwitchA(config-if-Vlan40)# vxlan arp-suppression

SwitchA(config-if-Vlan40)# exit

Save Configuration:

SwitchA# write memory

Enter Configuration Mode:

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

Create VTEP Interface:

Enter the interface configuration mode for the VTEP interface named vtep1 using interface vtep1.

Assign the IP address 10.10.10.1/24 to the VTEP interface using the ip address command.

Exit the interface configuration mode.

Map VNI 400 to VLAN 40:

Enter the VLAN configuration mode for VLAN 40 using vlan 40.

Map the VNI 400 to VLAN 40 using the vn-segment 400 command.

Exit the VLAN configuration mode.

Enable ARP Neighbor Suppression:

Enter the interface configuration mode for VLAN 40 using interface Vlan40.

Assign the anycast IP address 192.168.40.254/24 to the VLAN interface using the ip address command.

Enable ARP neighbor suppression using the vxlan arp-suppression command.

Exit the interface configuration mode.

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 VTEP and map the VNI to VLAN 40 on Switch A, ensuring the specific requirements for IP addressing and ARP neighbor suppression are met.

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 References:

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.
