Important Dell EMC D-SNC-DY-00 Exam Questions

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.

IPv6 Addressing Guide

Answer: B

Explanation:

The show interface breakout port slot/slot command displays the breakout modes available for the specified port. Breakout modes determine how a single high-speed port can be split into multiple lower-speed ports, providing flexibility in network port configurations.

Port Breakout Configuration Guide

Answer: B

Explanation:

Based on the exhibit, Router-2 has the highest priority (90) in VRRP group 10. In VRRP, the router with the highest priority becomes the primary (master) router. Therefore, Router-2 is the primary VRRP router for VRRP group 10.

VRRP Protocol Overview

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.

VRRP Configuration Guide

Answer: A

Explanation:

Here are the steps to configure the required VLAN translations on a Dell SONiC switch:

Map a Single-Tagged CVLAN 100 to SVLAN 200 on Interface Eth1/1:

sonic# configure terminal

sonic(config)# interface Ethernet1/1

sonic(config-if-Ethernet1/1)# switchport mode trunk

sonic(config-if-Ethernet1/1)# switchport vlan mapping 100 200

sonic(config-if-Ethernet1/1)# end

sonic# write memory

Map a Double-Tagged VLAN Packet with Outer CVLAN 100 and Inner dot1q 200 to SVLAN 300 on Interface Eth1/2:

sonic# configure terminal

sonic(config)# interface Ethernet1/2

sonic(config-if-Ethernet1/2)# switchport mode trunk

sonic(config-if-Ethernet1/2)# switchport vlan mapping 100 200 300

sonic(config-if-Ethernet1/2)# end

sonic# write memory

Comprehensive Detailed Step by Step Explanation with Reference:

Enter Configuration Mode:

Access the global configuration mode using the configure terminal command.

Configure Interface Eth1/1:

Enter interface configuration mode for Ethernet1/1 using the command interface Ethernet1/1.

Set the switchport mode to trunk with the command switchport mode trunk.

Configure the VLAN translation using the switchport vlan mapping 100 200 command, which maps CVLAN 100 to SVLAN 200.

Exit the interface configuration mode by typing end.

Save the configuration with write memory.

Configure Interface Eth1/2:

Enter interface configuration mode for Ethernet1/2 using the command interface Ethernet1/2.

Set the switchport mode to trunk with the command switchport mode trunk.

Configure the double-tagged VLAN translation using the switchport vlan mapping 100 200 300 command, which maps packets with outer CVLAN 100 and inner dot1q 200 to SVLAN 300.

Exit the interface configuration mode by typing end.

Save the configuration with write memory.
