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 correct answer is A . Versa template-based provisioning is designed to separate common configuration from site-specific values. A device template can define common interface, service, routing, and SD-WAN behavior, while variables and device bind data provide unique values for each appliance. This allows the same template to be reused across many branches while assigning different WAN IP addresses, gateways, VLAN IDs, circuit names, or other per-site parameters during onboarding.

In this scenario, Branch-A and Branch-B use the same template but receive different WAN VLAN IDs from bind data. That is normal and expected in a scalable SD-WAN deployment. Without variables, administrators would need to create a separate template for every site, which would be operationally inefficient and increase configuration drift.

The Controller does not automatically rewrite VLAN IDs after IPsec comes up; VLAN IDs must be part of the generated device configuration. It is also not required to duplicate the device template for each branch. The correct Versa design is reusable templates plus unique bind-data values.

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.

The correct answers are C and D . Versa templates are designed to reuse common configuration while still allowing per-device customization. Template variables allow the same template to be deployed to multiple appliances while using device-specific values such as addresses, VLAN IDs, DHCP information, or other bind-data values. Versa documentation for deploying templates describes assigning values to variables contained in a main template that are specific to the device. This makes option C correct.

Option D is also correct because Versa workflows are used to create templates for VOS device configuration. Versa documentation states that workflows are used to create templates to configure VOS devices, and also to create templates for application steering, spoke groups, and service chains.

Option A is not correct in the normal Versa Director onboarding model because a group of devices is associated with one staging template and one post-staging template, rather than multiple device templates being stacked per appliance. Option B is also incorrect because service templates are optional reusable service-specific fragments. Versa documentation states that service templates can be used by multiple device templates and device groups, but it does not require every appliance to have one.

The correct answers are B and D . In the exhibit, Enable Auto Switchover is not selected. However, the Failover Timeout value is configured as 300 seconds . Versa Director HA documentation states that the Failover Timeout is the timeout period before the standby Director node can promote itself to become the active Director node. Therefore, if the active or primary Director fails, the backup Director can automatically assume the active role after the failover condition and timeout are met.

The important distinction is that Auto Switchover controls revertive behavior after recovery, not the initial standby takeover during failure. Versa documentation explains that Director HA is non-revertive by default. This means that when the designated master or primary Director comes back online after recovery, it is not automatically promoted back to active unless automatic switchover is enabled. To make the designated active Director automatically reclaim the active state after recovery, Enable Auto Switchover must be selected and the Auto Switchover Timeout must expire.
