2024 New Training Course D-SNC-DY-00 Tutorial Preparation Guide [Q11-Q34]

Explanation:
* Ingress VTEP performs a route lookup that is based on the destination IP address.
* Ingress VTEP encapsulates the packet with VXLAN and sends it on the appropriate VNI segment.
* Egress VTEP determines that the host is local to the VNI and switches the packet.
* Egress VTEP bridges the packet after decapsulation.
Steps and Correct Order:
* Ingress VTEP performs a route lookup that is based on the destination IP address.
* The ingress VTEP (Virtual Tunnel Endpoint) first needs to determine the next hop for the packet.
This involves performing a route lookup using the destination IP address.
* Ingress VTEP encapsulates the packet with VXLAN and sends it on the appropriate VNI segment.
* Once the route lookup is complete, the ingress VTEP encapsulates the packet in a VXLAN header, which includes the appropriate VNI (VXLAN Network Identifier) segment, and forwards it.
* Egress VTEP determines that the host is local to the VNI and switches the packet.
* The egress VTEP receives the encapsulated VXLAN packet, decapsulates it, and then checks its local VNI to determine if the destination host is within the same VNI.
* Egress VTEP bridges the packet after decapsulation.
* After determining the destination host’s locality, the egress VTEP bridges the packet to the appropriate interface to deliver it to the final destination.

Explanation:
Here is the step-by-step configuration for R1:
* Enter BGP Configuration Mode:
R1# configure terminal
R1(config)# router bgp 1
* Configure the BGP Neighbor:
R1(config-router)# neighbor 10.10.12.2 remote-as 2
* Redistribute Connected Routes into BGP:
R1(config-router)# redistribute connected
* Exit BGP Configuration Mode and Save the Configuration:
R1(config-router)# end
R1# write memory
Comprehensive Detailed Step by Step Explanation with References:
* Enter BGP Configuration Mode:
* To configure BGP on R1, you need to enter global configuration mode and then enter BGP
* configuration mode with the AS number. Since R1 is in AS 1, you use the command router bgp 1.
* Configure the BGP Neighbor:
* BGP neighbors must be manually specified. In this case, R1’s neighbor is R2, which has an IP address of 10.10.12.2 and resides in AS 2. The command neighbor 10.10.12.2 remote-as 2 establishes this relationship.
* Redistribute Connected Routes into BGP:
* To ensure that all connected routes on R1 are advertised via BGP, you use the redistribute connected command. This ensures that any connected IPv4 routes are redistributed into BGP, meeting the requirement to advertise current and future connected routes.
* Exit BGP Configuration Mode and Save the Configuration:
* Once the configuration is complete, you exit BGP configuration mode by typing end and then save the configuration with the write memory command. This ensures that the changes persist after a reboot.

These steps provide a comprehensive guide to configure R1 to meet the specified requirements for BGP peering and route redistribution.

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.

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.

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

* 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.

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.

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.

In a symmetric Integrated Routing and Bridging (IRB) overlay network, the Source Virtual Tunnel End Point (VTEP) and the Destination VTEP route unencapsulated user traffic. Symmetric IRB ensures that routing occurs at both the ingress and egress VTEPs, allowing for optimized traffic flow and efficient network operations.

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.

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.

The ztp enable command is used to administratively enable the Zero Touch Provisioning (ZTP) process on the switch. This process allows the switch to automatically download and apply configuration files upon boot-up without manual intervention. The show ztp status command is used to check on the progress and status of the ZTP process, providing information about whether the process is active, completed, or encountered any issues.

The automated installation of Enterprise SONiC is typically performed using the HTTP protocol. During the Zero Touch Provisioning (ZTP) process, the switch retrieves configuration files and software images from an HTTP server, allowing for automated and streamlined deployments.

The command interface vxlan vtep-stacking followed by map vni 10010 vlan 100 maps the VLAN traffic that an SVLAN identifies to a VNI on a VTEP. In this context, SVLAN (Service VLAN) is being mapped to a VXLAN Network Identifier (VNI) for encapsulation and transport across the VXLAN tunnel.

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.

In the absence of a manually configured router ID, OSPF typically uses the highest IP address on the switch’s active interfaces. For Switch 3 in the exhibit, the highest IP address is 10.0.1.1 on Loopback 0. Therefore,
10.0.1.1 is used as the router ID for Switch 3.
