Free Practice Questions for Versa Networks VNX301 Exam

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 A, B, and D . For large-scale Versa Secure SD-WAN onboarding, common configuration is reusable through templates and grouping. A device template , also known as a post-staging template, provides the common base configuration that is applied to multiple VOS branch appliances. Versa documentation repeatedly shows configuration tasks being performed under Templates > Device Templates , where an organization is selected and the post-staging template is opened in Appliance view for common configuration.

A device group is also shared by multiple appliances because it groups devices that should receive the same template associations and common service behavior. This is the proper way to profile many branches with similar deployment requirements. Service templates are also shared objects. They are used to apply service-specific configurations, such as SD-WAN traffic steering, application steering, QoS, security, or other common services, across devices. Versa SD-WAN design documentation explains that application-steering templates automate business-intent policies and simplify management by combining application classification, forwarding-class mapping, and SD-WAN policy logic in a reusable template.

A workflow device is device-specific, and device bind data contains site-specific values such as interface addressing, gateways, VLANs, and other per-branch parameters. Therefore, those are not the shared configuration objects.

The correct answers are A, B, and E . Versa Director supports multiple notification and event-publishing mechanisms. For email-style system and alarm notifications, Versa Director supports SMTP configuration. The Director documentation lists Configure SMTP Notifications and explains that email templates require SMTP notifications to send test emails or operational messages.

Versa Director also supports webhook notifications. The Director GUI overview states that Notification Configuration includes webhook-based notifications for alarms, and the Director documentation includes a dedicated workflow for configuring webhook notifications for alarms.

Kafka is also a supported event-notification method. Versa’s Kafka Notifications documentation states that Versa Director can publish event notifications to an Apache Kafka server when events occur on a Director node or a VOS device. It also lists notification topics for device events, Director events, Director task notifications, and object-change event notifications.

MMS is not a Versa Director system event notification method. SMS can be configured for text messaging in some notification contexts, but for the three methods listed for system event notifications in this answer set, the verified options are SMTP, Webhook, and Kafka.

The correct answer is A . Versa CGNAT troubleshooting documentation includes per-pool and resource counters that show allocation behavior and failures. The counters include values such as bindings allocated, bindings freed, allocation failures, out-of-address errors, and out-of-ports errors. It also shows that CGNAT source-port resources are divided and distributed to worker threads by Versa RFD/RFM, and that allocated source-port ranges can be viewed using show rfm table src-port allocated.

If out-of-ports errors increase while out-of-address errors remain zero, the pool still has usable translated IP addresses, but the available port resource for NAT bindings is exhausted. This commonly occurs when too many concurrent sessions share a limited public IP or source-port range. The corrective action would be to expand the NAT resource, add more public translated IPs, adjust port allocation, or reduce excessive session usage.

A missing NAT IP pool would more likely produce out-of-address problems. A wrong zone match might prevent translation entirely, and OSPF in the LAN VR is unrelated to CGNAT port-resource exhaustion.

The correct answer is A . Versa monitoring documentation states that when an administrator selects a provider organization in Director and opens the Summary tab, the screen displays several panes. The Asset Inventory pane displays the number of tenants, SD-WAN branches, SD-WAN Controller nodes, vCPEs, SD-WAN hubs, uCPEs, Director nodes, and Analytics nodes in the organization.

This pane is useful for quickly validating the managed estate and confirming whether expected infrastructure objects exist under the provider organization. It also provides a Details button to display asset information in tabular format, which can help during audits or operational checks.

Package Information shows software package details for the selected node, not organization-wide inventory. Uptime shows how long a node and its software have been running. High Availability shows Director HA information. These panes are useful, but they do not provide the organization-level asset count requested in the question.

The correct answer is A . During Versa SD-WAN onboarding, the branch uses the staging server only in the early part of the process. Versa documentation states that in Stage 1 , the branch starts an IKE session with the staging server, receives an IP address, and is informed of the Versa Director IP address. In Stage 2 , Versa Director pushes the stage-two configuration to the branch through the staging server. In this stage-two configuration, the Controller IP address is given as the remote IP address in the IPsec profile , and the branch is rebooted. After reboot, the branch should establish the IKE session with the Controller.

If the branch keeps trying to connect to the staging server after the stage-two reboot, the most likely issue is that the stage-two IPsec profile still points to the staging server or does not contain the correct Controller remote IP. Analytics, DHCP, and URL filtering settings do not determine whether the branch moves from staging-server connectivity to Controller IKE connectivity.

In the exhibit, the Add Associate Interface/Network window has Interface selected, and the interface name is set to vni-0/0 . The DSCP rewrite option is not available because rewrite behavior is intended to be applied at the network association level for the WAN network, not directly while associating only the physical/logical interface. For WAN-facing CoS, the scheduler and shaping parameters can be attached to an interface, but DSCP rewrite policies are applied to remark traffic as it exits through a network context.

Versa SD-WAN design documentation explains that QoS rewrite rules rewrite packet QoS attributes as packets leave the VOS device, and that rewrite rules can modify IEEE 802.1p bits, IPv4 TOS/DSCP bits, and IPv6 traffic class bits. It also explains that a rewrite policy is commonly applied on a WAN network to remark traffic based on the forwarding class and loss priority assigned by QoS or App QoS policies. In the design example, Versa explicitly describes applying a QoS propagation or rewrite policy on the MPLS WAN network to remark traffic to a DSCP value. Therefore, the issue is the association type: it is set to Interface, not Network.
