Set. and Act. Route maps in Enterprise SONIC are used for controlling and modifying routing information. They contain a series of commands with matching criteria and actions. The permit or deny clause within route maps determines whether the matching routes are permitted or denied from being redistributed.References:* Dell Technologies SONiC Route Map Configuration Guide* Dell Networking Configuration GuideQUESTION 22What is the impact of entering the qos-mode uniform command on a VTEP interface?  The DCSP values for the local and remote VTEPs are synchronized.  The local VNI value is aligned to the VNI of the remote VTEP interface.  A uniform VNI value is configured on local and remote VTEP interfaces.  The payload DSCP value is copied to the outer header DSCP value. Entering the qos-mode uniform command on a VTEP interface ensures that the DSCP (Differentiated Services Code Point) value of the payload is copied to the outer header DSCP value. This maintains the Quality of Service (QoS) markings across the VXLAN tunnel, allowing consistent traffic prioritization.References:* Dell Technologies SONiC documentation* VXLAN and QoS Configuration GuideQUESTION 23What does the show vian command display?  All configured VLANs  Only VLANs in an active state  All 4094 VLANs The show vlan command displays all configured VLANs on the device, including their status, ports, and other relevant details. It does not limit the display to only active VLANs or all possible VLANs but shows those that are currently configured.References:* Dell Technologies SONiC Command Reference Guide* Dell Networking Configuration GuideQUESTION 24What is an iBGP neighbor relationship?  Two BGP neighbors have the same autonomous system numbers  Two BGP neighbors share L2VPN EVPN advertisements.  Two BGP neighbors share only native BGP networks.  Two BGP neighbors share only private networks. An iBGP (Internal Border Gateway Protocol) neighbor relationship is established between two BGP routers within the same autonomous system (AS). This relationship allows for the exchange of routing information within the AS, ensuring that internal routes are propagated correctly.References:* Dell Technologies SONiC Routing Guide* BGP Configuration GuideQUESTION 25Which two additional Q-in-Q VLAN tunnel configuration steps must be followed if the provider network uses a VXLAN overlay?  Configure VLAN Translation.  Map the SVLAN traffic to a VNI.  Remove the CVLAN-to-SVLAN mapping.  Configure the BGP route-target and route-distinguisher. * 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.References:* Dell Technologies SONiC documentation* VXLAN Configuration GuideQUESTION 26What is the purpose of the write erase boot command option?  Delete the startup and enable zero touch provisioning.  Remove user-installed packages and tile changes.  Delete the startup configuration and the management interface configuration.  Delete the running configuration and all user accounts. The write erase boot command option deletes the startup configuration and enables zero touch provisioning (ZTP). This is used to reset the switch to its default state and prepare it for automated configuration through ZTP.References:* Dell Technologies SONiC Command Reference Guide* Switch Configuration GuideQUESTION 27Refer to the exhibit.What is the primary VRRP router for VRRP group 10?  Router-1  Router-2  Router-3 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.References:* Dell Technologies SONiC VRRP Configuration Guide* VRRP Protocol OverviewQUESTION 28Refer to the exhibit.What can be determined from this show command?  Traffic below 100 KB is marked as congested  ECN is enabled for all colors  ECN is enabled for all DSCP values  There is a 10% probability that traffic is marked as congested 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.References:* Dell Enterprise SONiC documentation* Dell Technologies InfoHubQUESTION 29Which network devices route unencapsulated user traffic in a symmetric IRB overlay network?  Leaf router and spine router  Source VTEP and destination VTEP  Autonomous system boundary router and source VTEP  Capability extended next hop router and leaf router 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.References:* Dell Technologies SONiC documentation* VXLAN Configuration GuideQUESTION 30Create port channel 10 on interfaces Eth 1/11 and 1/12, so that it connects to an already configured switch.

These modes provide flexibility in network design and enable the switch to support different types of network connections and bandwidth requirements.References:* Dell S5248F Switch Data Sheet* Dell Technologies InfoHubQUESTION 33Refer to the exhibits.PC1 has a valid address on the 192.168.10.0 network, and PC2 has a valid address on the 192.168.20.0 network.What happens when a ping command is issued between PC1 and PC2?  The ping is successful because there is a route to 10.0.1.1, which is connected to 1(10.2.2, which is connected to PC2.  The ping is unsuccessful because there is no route to the VLAN 10 gateway address of 192.168.10.254.  The ping is successful because there are two routes from switch1 to switch2 which are connected to PC2.  The ping is unsuccessful because there is no route from switch 1 to the 192.168.20.0 network. * Network Topology Analysis:* PC1 is on VLAN 10 with an IP address in the 192.168.10.0/24 subnet.* PC2 is on VLAN 20 with an IP address in the 192.168.20.0/24 subnet.* The network uses OSPF for routing between the switches.* The OSPF area is 0, and all switches have loopback interfaces for OSPF.* Routing Table Examination (from switch1):* The show ip route command output from switch1 provides a detailed look at the routing table.* Routes to the 192.168.10.0/24 network (directly connected via Vlan10) are present.* No routes to the 192.168.20.0/24 network are listed in switch1’s routing table.* Explanation:* For PC1 to communicate with PC2, switch1 must have a route to the 192.168.20.0/24 network.* The absence of a route to the 192.168.20.0/24 network in switch1’s routing table means that switch1 cannot forward packets destined for 192.168.20.0/24.* Therefore, any ping from PC1 to PC2 will be unsuccessful as switch1 does not know how to route packets to PC2’s network.* Verification with Dell SONiC:* In Dell SONiC environments, OSPF is configured to ensure dynamic routing.* The configuration must include all necessary networks for inter-switch routing.* If a network (like 192.168.20.0/24) is not included in OSPF configurations on switch1, routes to that network will not be advertised or learned, leading to failed connectivity tests like the ping from PC1 to PC2.References:* Dell Enterprise SONiC Deployment Guide* Dell Technologies Networking – SONiCQUESTION 34Configure a VRF called “VrfGreen” and the static route in it to network 172.16.128.64/28 through next-hop10.10.10.1. Set an administrative distance of 213. see the explanation for all step by step solution with all explanation.Explanation: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 memoryComprehensive 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.References:* Dell Technologies Networking – SONiC* Dell Enterprise SONiC Deployment GuideThese steps provide a comprehensive guide to configure a VRF and a static route within that VRF on a SONiC-based switch, ensuring the specific requirements for routing and administrative distance are met.QUESTION 35Refer 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?  An incorrect IPv6 address type was used for interface Eth1/56 of SONiC-2.  A spanning-tree is blocking the routed link.  IPv6 is not enabled on interface Eth 1/1 of SONiC-1.  There is a cable that is unplugged between SONiC-1 and SONiC-2. 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.References:* Dell Technologies SONiC documentation* IPv6 Addressing GuideQUESTION 36An administrator issues The ztp enable and show ztp status commands. What two objectives are they trying to accomplish?  Administratively enable the ZTP process.  Remove the ZTP function from the switch.  Disable the ZTP process.  Check on the progress of the ZTP process. 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.References:* Dell Technologies SONiC documentation* Dell Networking Configuration GuideQUESTION 37A customer must configure a peer link between two switches in the L2 MC-LAG scenario.SwitchB has already been configured.
