Versa Networks Updated VNX301 Exam Questions and Answers by irha

The correct answers are B and C . During a migration from a legacy WAN, such as MPLS Layer 3 VPN, to Versa Secure SD-WAN, an SD-WAN gateway is used to allow communication between SD-WAN-enabled branches and legacy WAN sites. Versa SD-WAN design guidance states that an SD-WAN gateway allows sites connected to the SD-WAN VPN network to communicate with sites connected to a legacy MPLS VPN network. It also explains that this gateway facilitates route exchange between the MPLS underlay network and the SD-WAN VPN network, typically using a dynamic routing protocol such as BGP.

For this design, the hub or gateway must be configured with the Gateway option for the underlay transport so it can act as the interconnect point between the legacy and SD-WAN domains. Versa documentation further describes configuring a BGP peering session on the MPLS transport VR of the gateway to exchange routes from the MPLS provider to the SD-WAN network, and notes that Director Workflows can automate this configuration. Spoke-to-Spoke-Direct is not sufficient for legacy interconnect, and SD-WAN traffic steering policies do not advertise routes.

The correct answer is A . Versa CGNAT troubleshooting documentation provides a clear workflow for CGNAT issues. It first describes how to view CGNAT summary information using show orgs org-services < org > cgnat summary. It then shows how to view per-pool statistics using show orgs org-services < org > cgnat pools < pool-name > statistics. The sample output includes counters such as bindings-allocated , bindings-freed , alloc-failures , free-failures , out-of-address-errors , and out-of-ports-errors .

If these counters indicate failures, the next step is to inspect CGNAT state inside the vsmd daemon, including tenant state, ACL matching, pools, bindings, and source-port resources. This helps determine whether the issue is pool exhaustion, rule mismatch, resource allocation failure, or stale runtime state.

OSPF may affect routing but does not explain CGNAT allocation counters. Analytics may store logs but is not the dataplane authority for NAT allocation. Rebooting Analytics would not resolve CGNAT resource programming on the VOS device.

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 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.
