Which feature should be enabled to achieve this objective? A. Symmetric Forwarding B. Symmetric Routing C. Equal-Cost Multipath D. Packet Striping Answer: A Explanation: Symmetric Forwarding is the correct Versa SD-WAN feature for ensuring that return traffic between SD-WAN branches follows the same SD-WAN path on which the forward traffic was received. Versa documentation for SD-WAN traffic steering describes Symmetric forwarding as the option that specifies the path for reverse-direction traffic, meaning whether traffic returning from the destination branch to the originating branch should be sent on the same path on which it arrived. It further states that enabling symmetric traffic forwarding determines the reverse path for traffic returning from the destination branch to the originating branch. This is different from Symmetric Routing, which is a routing design goal or behavior, not the Versa SD-WAN forwarding-profile feature named in the product documentation. Equal-Cost Multipath can distribute flows across equal-cost routes, but it does not specifically guarantee that both directions of the same SD-WAN session use the same path. Packet Striping is used to split or distribute packets across multiple links for performance, not to enforce bidirectional path symmetry. Therefore, the verified Versa feature to enable is Symmetric Forwarding. 2.Examine the exhibit below.

You cannot get a Versa-Provider-Controller-VR IP address assigned, indicating that the IPsec tunnel to the corrector has not come up. You verified that the cables have been connected to the correct ports. What has caused this issue? Download Valid VNX301 PDF Dumps for Good Learning 4 / 8 A. The Controller IP address is incorrectly specified in the staging script. B. The default gateway is in not in the same subnet as the WAN IP address. C. The serial number was corrupted in the line feed. D. The incorrect port was specified in the staging script. Answer: D Explanation: The issue is caused by specifying the incorrect WAN port in the staging script. In the exhibit, the SOLDEU-R2 branch is physically connected to the Internet cloud through vni-0/0, while vni-0/1 is shown as the inter-device link toward SOLDEU-R1. However, the show interfaces brief output shows that the WAN IP address 192.168.122.121/24 has been assigned to vni-0/1.0, not to the Internet-facing interface. Since the cables are confirmed to be connected correctly, the mismatch must be in the staging script interface selection, not in the cabling. Versa documentation states that during SD-WAN staging, the branch establishes an IKE session with the Controller, and after that the Controller assigns an IP address to the branch device. Versa troubleshooting guidance also states that after transport connectivity to the Controller is established, the branch forms IKE-based IPsec connectivity, and if this succeeds, the ptvi interface toward the Controller comes up. If IKE/IPsec fails, the ptvi interface remains down. Because the staged WAN IP is placed on the wrong VNI interface, the branch cannot reach the Controller over the intended Internet transport, so the Controller tunnel does not come up. 3.You are configuring the BGP routing protocol between a Versa Secure SD-WAN CPE with AS number 64514 and two upstream service providers: SP1 with AS number 64515 and SP2 with AS number 64519. You want to prefer BGP routes learned from AS 64515 over routes learned from AS 64519. Which BGP path attribute would be used to accomplish this task? A. The BGP MULTI_EXIT_DISC path attribute B. The BGP ORIGIN path attribute C. The BGP LOCAL_PREF path attribute D. The BGP NEXT_HOP path attribute Answer: C Explanation: The correct answer is LOCAL_PREF. In BGP, the Local Preference attribute is used inside an autonomous system to influence which exit path is preferred for outbound traffic. In this scenario, the Versa Secure SD-WAN CPE receives routes from two upstream service providers, SP1 and SP2. To prefer routes learned from AS 64515 over routes learned from AS 64519, you would apply a BGP import or route policy that assigns a higher local preference to routes received from SP1. Versa SD-WAN design guidance shows this exact routing concept: an import policy can manipulate the Local-Pref attribute to prefer one advertised route path over another. The Versa output examples also display “ Local Preference ” as a BGP route attribute used in route selection. MULTI_EXIT_DISC, or MED, is generally used to influence how a neighboring AS enters your AS, not how your CPE prefers routes learned from different upstreams. ORIGIN is part of BGP best-path selection but is not normally the administrative tool used to prefer one provider. NEXT_HOP identifies the next-hop address and does not directly define route preference. 4.Examine the exhibit below. Download Valid VNX301 PDF Dumps for Good Learning 5 / 8 The exhibit shows a device group created for a new group of hubs. The device template called “ BMBF-TEMPLATE ” has an Address object called “ Server ” A network administrator creates the Class of Service Template called “ Ship-CoS-IT ” that has an Address object with the same name. Then it tries to onboard a new device to this device group. Which statement is true about the configuration that this device will have? A. The device configuration commit will fail. B. The device configuration will have the Address object that was created last. C. The device configuration will automatically create two copies of the same Address object. D. The device configuration will have the version of the Address object in the QoS template. Answer: D Explanation: The correct answer is D. In the displayed post-staging template association order, the device template BMBF-TEMPLATE is applied before the QoS service template Ship-CoS-IT. Versa documentation explains that device templates, also called post-staging templates, provide the baseline configuration for devices, while service templates are service-specific configurations that can be applied to device configurations. It also states that service templates are associated with device groups and that, in a device group, the administrator can choose the order in which service templates are applied. Because the QoS template is later in the shown association order, the final merged device configuration uses the Address object definition from the QoS template when the same object name exists in both templates. It does not automatically create two copies of the same Address object, because the object name is the key for the configuration element. It also should not fail merely because the same object name exists in a later template; the merge behavior resolves the effective configuration according to the template order. Therefore, the onboarded hub device receives the Server Address object version from Ship-CoS-IT, the QoS template. 5.As an administrator, you are migrating your legacy WAN to Versa Secure SD-WAN without changing the underlay network. You need to ensure that, during the migration process, legacy WAN sites are allowed to communicate with SD-WAN branches. Which two steps should be implemented to accomplish this task? (Choose two.) A. Apply the Spoke-to-Spoke-Direct topology for the SD-WAN branches. B. Using workflows, configure the Gateway option in the hub template for the underlay links. C. Configure BGP on the hub underlay links to advertise and receive the prefixes. Download Valid VNX301 PDF Dumps for Good Learning 6 / 8 D. Configure an SD-WAN traffic steering policy to advertise the SD-WAN routes. Answer: B, C Explanation: The correct answers are B and C. During a migration from a legacy WAN, such as MPLS Layer 3 VPN, to Versa Secure SD-WAN, an SD-WAN gateway is used to allow communication between SD-WAN-enabled branches and legacy WAN sites. Versa SD-WAN design guidance states that an SD-WAN gateway allows sites connected to the SD-WAN VPN network to communicate with sites connected to a legacy MPLS VPN network. It also explains that this gateway facilitates route exchange between the MPLS underlay network and the SD-WAN VPN network, typically using a dynamic routing protocol such as BGP. For this design, the hub or gateway must be configured with the Gateway option for the underlay transport so it can act as the interconnect point between the legacy and SD-WAN domains. Versa documentation further describes configuring a BGP peering session on the MPLS transport VR of the gateway to exchange routes from the MPLS provider to the SD-WAN network, and notes that Director Workflows can automate this configuration. Spoke-to-Spoke-Direct is not sufficient for legacy interconnect, and SD-WAN traffic steering policies do not advertise routes. 6.You are onboarding a branch with one WAN and one LAN interface. After a successful branch activation, the branch is not able to reach the Versa Controller. You realize that the WAN gateway IP address originally entered under the Device Bind Data menu in Versa Director is incorrect. Which action will you perform to solve the problem? A. Change the WAN gateway IP address on the branch appliance from the Versa Director Appliance context. B. Change the WAN gateway IP address in Device Bind Data and onboard the branch appliance again. C. Connect to the branch appliance from the Versa Controller Control VR and modify the WAN gateway IP address using the branch CLI. D. Reset the branch appliance from Versa Director to automatically ping the correct WAN gateway IP address. Answer: B Explanation: The correct action is to update the WAN gateway IP address in Device Bind Data and onboard the branch appliance again. Device Bind Data supplies site-specific values, such as WAN interface addressing and gateway information, that are merged with the workflow and template configuration during onboarding. If the wrong WAN gateway is entered, the branch may activate successfully from a workflow perspective, but the resulting WAN routing configuration is incorrect. As a result, the branch cannot establish proper transport reachability to the Controller. Versa troubleshooting documentation explains that, after establishing transport connectivity from a branch to a Controller, at least one WAN interface must be available, and the branch then establishes IKE-based IPsec connectivity to the Controller. If that IKE/IPsec connectivity fails, the Controller-facing ptvi interface remains down. Changing the configuration only from the Appliance context is not the best answer because the incorrect value originated in the bind-data source used for provisioning. Modifying it manually from the branch CLI is also not recommended because the device is managed by Versa Director and template-driven configuration. Resetting the device does not automatically discover or “ ping ” the correct gateway. The correct remediation is to fix the bind data and repeat onboarding so the branch receives the correct generated configuration.

The tvi-0/603 interface is paired with an interface in another VR for the default route. B. The IP address configured on the tvi-0-603 interface its misconfigured by the template. C. Any unknown IP unicast destination will use the tvi-0/603 interface for its exit. D. The tvi-0/603 interface is a stub interface for black holing an unknown IP unicast destination. Answer: A, C Explanation: The correct answers are A and C. The route table shown in the Versa SD-WAN design documentation includes a default route, 0.0.0.0/0, with next hop 169.254.0.2 and exit interface tvi-0/603.0. A default route is used when no more specific route exists in the routing table, so any unknown IPv4 unicast destination will follow that active default route through the tvi-0/603 interface. This directly supports option C. The same design context describes local or central internet breakout, where Director workflows create TVI-based connectivity for breakout or gateway-style forwarding. In Versa SD-WAN, TVI interfaces are commonly used as internal virtual tunnel interfaces between routing instances, such as between a tenant LAN VR and a transport or breakout VR. The documentation also describes virtual TVI interface pairs being created by Director workflows between VRs for gateway routing use cases. Therefore, option A is also correct: tvi-0/603 is paired with another interface in another VR to support the default-route forwarding path. The IP address is not shown as misconfigured; 169.254.x.x addressing is commonly used for point-to-point internal TVI links. The route is also not a blackhole route, because it has an active next hop and an exit interface. 8.Examine the exhibit below. Download Valid VNX301 PDF Dumps for Good Learning 8 / 8 Referring to the exhibit, which two statements are correct? (Choose two.) A. All branches will have the same VLAN ID for the LAN network. B. All branches can have separate VLAN IDs on the MPLS WAN network. C. The VLAN ID must be provided for the INET WAN network. D. The VLAN ID field MPLS-WAN network is incorrect. Answer: A, B Explanation: The correct answers are A and B. In the exhibit, the LAN interface shows a fixed VLAN ID value of 100. Because this value is directly configured in the template rather than represented as a per-device variable, every branch that uses this template will receive the same LAN VLAN ID. This supports option A. Versa configuration examples show that VLAN-tagged interfaces are created by defining logical units with a vlan-id, and organizations then use those tagged interfaces for traffic identification and routing services. For the MPLS WAN network, the VLAN ID field is shown as a variable or bind-data style value rather than a fixed number. This allows each branch device to receive a different MPLS VLAN ID during onboarding, depending on the branch-specific values supplied in the workflow or device bind data. Therefore, branches can have separate VLAN IDs on the MPLS WAN transport, which supports option B. Versa SD-WAN troubleshooting output also shows WAN interfaces as logical VNI sub interfaces, such as vni-0/1.0 and vni-0/2.0, mapped to SD-WAN transport networks like INET and MPLS. Option C is incorrect because an INET interface can be untagged, commonly represented with VLAN ID 0. Option D is incorrect because the MPLS VLAN field is intentionally parameterized, not incorrectly configured.
