Pass the Versa Networks Administrator SD-WAN Specialist VNX301 Questions and answers with Dumpstech

The correct answer is A . Versa documentation states that from a Director node, administrators can monitor the Director node itself, provider organizations, tenants, and VOS devices. The procedure begins by selecting the Monitor tab in the top menu bar. When a Director node is selected, the monitor screen displays panes such as System Detail , Recent Events , Package Information , Uptime , High Availability , and License .

This view is intended for operational monitoring and troubleshooting. It allows administrators to see system resource status, recent alarms and events, software package details, uptime, HA configuration, and licenses installed on managed VOS devices.

Workflows are used for provisioning and template-based configuration, not monitoring these system panes. Analytics Search is useful for querying logs and flow records, but it is not the Director system-monitoring screen described in the question. Administration > Connectors relates to integration and resource connectivity rather than Director node health and license monitoring. Therefore, the correct location is the Monitor tab.

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 subinterfaces, 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.

The exhibit shows the Add CGNAT Pool configuration with the IP Address/Range option selected. The configured address range is named Visitors , with a low address of 192.168.10.100 and a high address of 192.168.10.150 . In CGNAT, this pool defines the translated source address resource used by matching NAT rules; it does not define the original inside source hosts. Therefore, matching sessions will have their source address translated to an address from this configured pool range, which makes option C correct. Versa’s CGNAT configuration examples show that a rule matches original source and destination prefixes, and then attaches a translated source pool to perform NAT.

The correct answer is B . In Versa SD-WAN onboarding, the branch progresses through three staging phases. In Stage 1 , the branch uses its factory-default configuration to start an IKE session with the staging server. After the IKE session comes up, the staging server assigns an IP address to the branch and notifies the branch of the Versa Director IP address. Versa Director is also notified that the branch has come up.

In Stage 2 , Versa Director pushes the stage-two configuration to the branch through the staging server. This stage changes the IPsec profile so that the Controller IP address becomes the remote IP. The branch reboots and then attempts to establish the IKE session with the Controller. If the device successfully completed Stage 1 but never forms the Controller IKE session, the failure point is Stage 2.

Stage 3 is later, when the device receives stage-three configuration, becomes operational, and creates Controller IPsec plus branch-to-branch VXLAN/ESP sessions. Therefore, the described issue is a Stage 2 staging failure.

The correct answer is A . In Versa SD-WAN traffic steering, forwarding profiles define how traffic is mapped to WAN circuits, how next hops are selected, and how traffic behaves when SLA conditions are violated. If the requirement is to stop traffic when no SLA-compliant path is available, the relevant behavior is the SLA Violation Action . Setting this option to Drop prevents the VOS device from forwarding the matching traffic over a circuit that does not satisfy the policy’s SLA requirements.

This is the opposite of using Forward , which allows traffic to continue even when the available next hops violate the SLA. Forward may be appropriate for best-effort applications where degraded delivery is better than no delivery, but it is not appropriate for strict business-critical applications that must not use a degraded path.

Nexthop Failure Action controls how the system behaves when a next hop fails, such as waiting for recovery or re-evaluating. Header compression affects packet overhead, and the recompute timer controls periodic recalculation timing. None of those settings directly enforce “drop when SLA is not met.”

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.

The correct answer is B . The exhibit shows the branch interface summary in Versa Director with a Live Data column. To populate real-time bandwidth graphs for WAN circuits, the administrator must select Live Data for the WAN interfaces that need to be monitored. Versa monitoring documentation states that, from a Director node, you can monitor VOS devices and organizations, and that Director, together with Versa Analytics, can poll VOS devices in real time to understand what is happening on the devices. This real-time information can be displayed to assist with troubleshooting.

Because the question asks for the current bandwidth of each WAN circuit, historical analytics alone is not sufficient. The dashboard must poll live statistics from the selected WAN circuits. In the exhibit, not all WAN interfaces appear to have Live Data selected; therefore, the graph is not populated for all circuits. Refreshing the page does not enable polling and will not solve the missing data condition. Selecting only MPLS would populate only the MPLS circuit, not all WAN circuits. Unselecting and reselecting only the INET circuit would affect only that one interface. Therefore, Live Data must be selected for all WAN circuits whose current bandwidth should be displayed.

The correct answer is A . In Versa Secure SD-WAN onboarding, the branch moves through three staging phases before becoming fully operational. Versa documentation states that in Stage 3 , Versa Director pushes the stage-three configuration to the branch device over the IKE session and reboots the branch. After this stage, the branch becomes fully operational and is part of the customer SD-WAN network. At this point, IKE and IPsec sessions are created between the branch and Controller , and VXLAN and ESP sessions are created between branch to branch .

This distinction is important because the Controller connection is used for SD-WAN control-plane functions, while branch-to-branch overlay communication uses tunnel encapsulation for data forwarding. The documentation also notes that branch-to-branch ESP is maintained using a lightweight DH key-pair proprietary protocol.

Options B, C, and D are incorrect. HTTPS to Director alone does not represent the complete SD-WAN operational tunnel state. BGP to Analytics is not the required operational tunnel set. GRE-only tunnels without IPsec do not match the Versa Stage 3 SD-WAN tunnel behavior described in the staging documentation.

The correct answer is A . Versa CGNAT troubleshooting documentation provides commands to inspect CGNAT state inside the vsmd daemon. To view summary information about configured tenants, the document instructs administrators to issue show cgnat tenants . The sample output shows each tenant ID and counters such as the number of configured rules, pools, DS-Lite service chains, 6RD service chains, static NAT entries, subscribers, endpoint-independent mapping entries, endpoint-independent filtering entries, and softwires.

This command is especially useful when CGNAT configuration appears correct in Director but translation is not happening, because it confirms whether the runtime dataplane process actually has the tenant CGNAT state.

show interfaces brief shows interface status and IP addressing. show alarms shows event notifications, and show system uptime shows how long the system has been running. These are useful operational commands but do not show CGNAT tenant programming inside vsmd.

The correct answer is C . In Versa Secure SD-WAN, Direct Internet Access, or DIA, provides local internet breakout from the branch rather than backhauling internet-bound traffic through a hub. Versa design documentation explains that the DIA architecture creates an internal connection between the tenant VRF and the WAN transport VR and uses CGNAT to translate internet-bound LAN traffic to the public IP address associated with the WAN transport interface. It specifically states that the main DIA components include the CGNAT function for translating internet-bound traffic and that DIA is configured using Director Workflows when configuring tunnels.

When the workflow template is used and the DIA option is selected for the internet breakout tunnel, Director automatically builds the required DIA infrastructure, including the NAPT/CGNAT configuration associated with the internet-facing transport network. This is why manual creation of the CGNAT pool and rule is not required in the workflow-based method. Option A describes a manual configuration approach, not the workflow-generated behavior. Option B is incorrect because NAT must be associated with the internet-facing breakout path, not simply the LAN interface. Option D is incorrect because DIA normally requires address translation for LAN users accessing the public internet.
