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 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 A . Versa link-bandwidth troubleshooting documentation explains that a VOS device can be configured as a Versa speed-test client, a Versa speed-test server, or both simultaneously. After the server is configured, the client starts the test by initiating a TCP-based connection toward the speed-test server. The server listens on port 5201 . The documentation includes an explicit note that if the VOS device is behind a firewall, port 5201 must be open .

This is different from the SD-WAN overlay data path, which commonly uses UDP-based transport encapsulation, and different from internet speed-test traffic, which uses other ports depending on the specific test type. In this scenario, the question states that a Versa speed-test server was configured, so the relevant requirement is TCP 5201 reachability from the client to the server.

TCP 443 may be used for management or web access, UDP 4790 is associated with SD-WAN transport encapsulation, and UDP 53 is DNS. None of those replace TCP 5201 for Versa speed-test server operation.

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 branch troubleshooting documentation states that the provider organization should have MP-BGP configured for SD-WAN deployments so that notifications for all relevant branch events are delivered to the Versa Director node. This is significant during onboarding because branch lifecycle events, such as branch-connect and branch-disconnect, help Director determine where the branch is in the staging process and whether the next configuration push should occur.

MP-BGP does not replace IKE or IPsec. The branch still establishes IKE/IPsec to the staging server or Controller depending on the staging phase. MP-BGP also has nothing to do with URL filtering category updates. While BGP can be used in LAN or WAN routing designs, the specific issue described here concerns provider-organization SD-WAN control-plane event delivery.

Therefore, if branch lifecycle events are not appearing properly, validating provider-organization MP-BGP configuration is part of the correct troubleshooting workflow, especially in addition to checking data-path and IPsec connectivity.

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 . Versa SD-WAN data-path troubleshooting documentation instructs administrators to connect to the VSM control plane with vsh connect vsmd and then use show vsm p2mp local-tunnel-sites 0 to check the status of local site objects. The example output includes the local site key, neighbor IP, site type, site name, branch ID, tenant ID, and detailed WAN link information. It also shows fields such as WAN local VRF ID, WAN local link name, circuit information, link ID, behind-NAT status, shaping rate, public and private addresses, link flags, transport domain, and SLA interval.

This command is therefore highly relevant when validating whether the local SD-WAN site has learned and built the correct WAN transport objects for overlay tunnel creation. If a circuit is mapped to the wrong transport domain or has incorrect NAT/public/private address state, the local-tunnel-site output is one of the best places to confirm it.

The other commands are useful for software version, CGNAT summary, or CPU usage, but they do not show the detailed SD-WAN local tunnel-site transport mapping.

The correct answer is A . In Versa SD-WAN forwarding profiles, next-hop priorities define which circuits are preferred. When the Load Balance next-hop selection method is used and two circuits share the same priority, sessions can be distributed across those equal-priority paths as long as they are usable and SLA-compliant. A lower priority number represents a more preferred group than a higher priority number. Therefore, two circuits with priority 1 are preferred over LTE with priority 2 .

In this scenario, both internet circuits are healthy and both have priority 1. The VOS device should load-balance sessions across those two circuits. LTE remains available as a lower-priority backup path and would normally be considered only when the preferred internet circuits are unavailable, fail path checks, or no longer meet the applicable policy conditions.

Traffic is not replicated because replication is a separate feature and not implied by Load Balance. The branch does not drop traffic while valid paths exist. LTE is not preferred merely because its priority number is higher; in path selection, priority 1 is preferred over priority 2.

The correct answer is B . Versa documentation describes checking for asymmetrical SD-WAN paths when troubleshooting bandwidth and throughput issues. It gives the example of traffic being transmitted on one transport network and returning on another transport network that has different bandwidth. To check whether traffic is traversing an asymmetrical SD-WAN path, Versa recommends using show orgs org organization-name sessions sdwan brief.

In that output, the key fields are RX WAN CKT and TX WAN CKT . If the SD-WAN paths are symmetrical, the circuits shown in the RX and TX WAN circuit fields must be the same on the local and remote sites. If traffic goes out over Internet and returns over MPLS, throughput may differ depending on the bandwidth and quality of each circuit.

Source and destination zones are security-policy concepts, while BGP local preference and MED are routing attributes. Tenant ID and VSN ID identify context, but they do not directly prove directional WAN-circuit asymmetry.

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.
