VNX301 Exam Dumps and Practice Questions

The correct answer is B. In the exhibit, Versa Director shows multiple branch interfaces and a Live Data column. To populate the bandwidth graph with current real-time statistics for all WAN circuits, Live Data must be selected for each WAN circuit that should be monitored. Versa documentation states that from a Director node, administrators can monitor VOS devices, provider organizations, tenants, events, and alarms. It also explains that Versa Director, together with Versa Analytics, can poll VOS devices in real time to provide visibility into what is happening on those devices and to assist with troubleshooting.

Because the requirement is to find the current bandwidth of each WAN circuit, simply refreshing the page is not enough. Refreshing only reloads the dashboard; it does not enable real-time polling for interfaces that are not selected. Selecting Live Data only for MPLS circuits would populate only MPLS-related data and would not satisfy the requirement for all WAN circuits. Unselecting and reselecting only the INET circuit affects only that one circuit. Therefore, the correct operational step is to enable Live Data for all WAN circuits shown in the branch interface dashboard.

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 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. 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 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.
