Free Versa Networks VNX301 Practice Exam with Questions & Answers

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.

In Versa SD-WAN, a Spoke-to-Hub-Only topology is specifically designed for deployments where spoke branches communicate only with hub resources and not with other spokes. Versa’s SD-WAN design documentation states that in a spoke-to-hub-only topology, the default behavior is that only hub routes are advertised, and spoke routes are not re-advertised by the hub branch. It also explains that this topology is used when spokes do not have to communicate with each other.

Even though the hub in the exhibit advertises a default route, that does not change the topology behavior into spoke-to-spoke communication. The default route can attract unknown traffic from the spokes toward the hub, but the Spoke-to-Hub-Only policy prevents the spoke prefixes from being redistributed or imported in a way that allows spoke-to-spoke reachability. Versa documentation further shows that spoke routes are filtered using BGP communities and import policies, and that the spoke route table contains only destinations behind the hubs, not other spoke routes.

The correct answers are A and C . If the onboarding VPN tunnel from the branch device to the Controller is up, the branch has reached at least the initial staging/control connectivity stage. Versa troubleshooting documentation explains that after a branch establishes IPsec connectivity to the Controller, the Controller sends a branch-connect notification to Versa Director. In response, Director pushes staging configuration and continues the onboarding lifecycle. If the expected later notification is not seen, the branch has not completed staging and further onboarding/debug steps are required.

The Tasks list in Versa Director is useful because device deployment and onboarding actions are executed as Director tasks. If template commit, workflow deployment, device claiming, or configuration push fails, the task output can show the error. The Unknown Devices dashboard is also relevant because a device that reaches the Controller but cannot be matched or fully associated with an expected workflow/appliance record may appear as an unknown device awaiting administrative review. The Monitor dashboard is not the best choice because the device is missing from the Appliances list and has not completed onboarding. Resource Pool is related to connector resources, not branch onboarding completion.

The correct answer is A . The exhibit shows that the IPsec VPN is being configured with Tunnel Routing Instance: XIAN-Control-VR . However, the question states that the tunnel is toward a non-SD-WAN site over the INET-Transport-VR . For a site-to-site IPsec tunnel, the tunnel routing instance must match the routing instance used to reach the peer public IP address. In this case, the remote non-SD-WAN peer is 10.1.1.1 , and the intended underlay transport is INET-Transport-VR , not the Control VR.

Versa troubleshooting documentation explains that routing instances are used to define where traffic is sourced and forwarded. For example, configuration examples select routing instances when enabling services or initiating tests, and traffic must use the correct WAN or transport routing instance to reach the remote endpoint. Versa branch troubleshooting also emphasizes that after transport connectivity is available, the branch establishes IKE-based IPsec connectivity; if that connectivity fails, the IPsec-related interface remains down.

Changing the routing instance to global would not be correct because the intended path is specifically INET-Transport-VR. A higher precedence value is not required to establish the tunnel. The policy selector shown already defines local-to-remote interesting traffic, and the key failure is the incorrect tunnel routing instance.

The correct answer is A . Versa’s handy troubleshooting CLI command reference lists show system package-info as the command used to view information about the VOS software image running on the CPE .

This command is useful before upgrade planning because it confirms the installed software package and helps validate whether the device is on the expected release. Administrators can compare the running version against the target upgrade image, verify upgrade prerequisites, and ensure that branch and Controller releases are compatible with required features such as internet speed testing, SD-WAN policy behavior, or security services.

show system uptime only tells how long the system has been running. show interfaces brief provides operational and administrative interface status, MAC address, tenant, VRF, and IP address information. show class-of-services interfaces brief helps troubleshoot QoS or shaping behavior. None of those commands directly identifies the VOS software package. Therefore, for checking the running image before an upgrade, the correct command is show system package-info.

The correct answers are A and D . Versa stateful firewall service includes classic firewall functions that track sessions and enforce traffic policy, and it can work with DoS policy enforcement. Versa’s CLI guide includes Configuring DoS policies under the security configuration area, where DoS rules can match on source, destination, services, applications, URL category, IP version, DSCP, TTL, EtherType, and other packet or session attributes, and can then apply aggregate or classified DoS profiles. This validates DoS protection as a stateful firewall/security service capability.

Application-Level Gateways, or ALGs , are also associated with stateful firewall/NAT behavior because they inspect and assist protocol handling for applications that embed addressing or dynamic port information inside the payload or control channel. This is part of traditional stateful firewall service behavior rather than UTM content inspection.

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 answers are A, B, and E . Versa Operating System, or VOS , is the software platform used for Versa SD-WAN branch and headend functions. Versa troubleshooting documentation explicitly refers to common runtime state across SD-WAN Controller, branch, and hub devices , confirming that VOS is used for Controller and branch-style SD-WAN roles. Versa monitoring documentation also lists SD-WAN branches, SD-WAN Controller nodes, SD-WAN hubs, vCPEs, and uCPEs as assets that are monitored and managed in Versa Director, which aligns with VOS being used as a branch/edge and controller platform.

VOS can also act as a uCPE platform . Versa documentation includes procedures to configure uCPE on a VOS device, showing that VOS can host or support uCPE deployment use cases.

The originally provided answer A, C, D is not correct. A Log Collector or log forwarder function belongs to the Versa Analytics architecture, not the VOS branch role; Versa’s design guide states that the log forwarder is part of the Versa Analytics node or can run as a standalone log-forwarder server. A Zookeeper arbiter is also not a standard VOS SD-WAN device role in this context.

The correct answer is B . Versa documentation for internet speed tests explains that when you run an internet speed test from a Director node, it creates approximately 200 sessions . This is useful for measuring aggregate throughput, but it does not represent the behavior of a single application flow. The same documentation states that you can run a speed test with a single session from the device CLI, and that this is useful for simulating file transfer rates when using SCP or FTP .

Therefore, when the goal is to understand how a single file transfer behaves, the CLI-based single-session test is the best option. A default Director-based test may produce higher aggregate results because multiple sessions can use parallelism and better fill the pipe.

show interfaces brief is useful for interface status and addressing, but it does not measure file-transfer throughput. SLA latency is useful for path-quality monitoring, but latency alone does not show single-session TCP throughput.

The correct answer is A . Versa’s handy CLI command reference lists show interfaces brief as the command used to view a list of interfaces along with their MAC addresses, operational and administrative status, tenant ID, VRF, and IP addresses. This is one of the first commands administrators run when validating device bring-up, staging interface assignment, WAN/LAN mapping, or whether a template applied interface addressing as expected.

For deeper interface troubleshooting, show interfaces detail provides additional information such as interface index, host interface, MTU, speed and duplex settings, RX/TX errors, and bridge information. However, for a quick overview of state and addressing across interfaces, show interfaces brief is the correct choice.

show system package-info identifies the running VOS software package. show system storage reports system storage resources. show coredumps shows generated core files. These are valuable operational commands, but they do not provide the requested interface status and addressing summary.
