Versa Networks VNX301 Practice Exam Questions & Answers

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 answers are A and C. Versa supports upgrading deployed VOS branch devices either directly on the VOS appliance or centrally through Versa Director. The Director-based method is performed from the Administration > Appliances area: Versa documentation says to select one or more Controller nodes or VOS devices, click the Upgrade Selected Appliances icon, choose the software image package, and proceed with the appliance upgrade. The same upgrade procedure is referenced for remaining VOS branch devices, including the option to upgrade branches individually or all at once.

A CLI-based upgrade using a software .bin package is also a valid operational method when the image is copied to the device and installed locally, particularly for controlled or recovery-style maintenance. Option B is not the best answer for already deployed branch upgrades because the Preferred Software Version field applies to zero-touch provisioning; Versa states that during ZTP, Director upgrades a branch to the preferred version if applicable. That setting influences onboarding behavior, not the normal upgrade workflow for already deployed branches. Option D is incorrect because System > Director Upgrade is used to upgrade the Versa Director node itself, not VOS branch appliances.

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.

The correct answer is A. Versa template-based provisioning is designed to separate common configuration from site-specific values. A device template can define common interface, service, routing, and SD-WAN behavior, while variables and device bind data provide unique values for each appliance. This allows the same template to be reused across many branches while assigning different WAN IP addresses, gateways, VLAN IDs, circuit names, or other per-site parameters during onboarding.

In this scenario, Branch-A and Branch-B use the same template but receive different WAN VLAN IDs from bind data. That is normal and expected in a scalable SD-WAN deployment. Without variables, administrators would need to create a separate template for every site, which would be operationally inefficient and increase configuration drift.

The Controller does not automatically rewrite VLAN IDs after IPsec comes up; VLAN IDs must be part of the generated device configuration. It is also not required to duplicate the device template for each branch. The correct Versa design is reusable templates plus unique bind-data values.

The correct answer is B. The DoS profile in the exhibit is a Classified Profile using Source IP Only as the classification key. For TCP flood protection, the profile is enabled and shows an Alarm Rate of 5000 packets per second, an Activate Rate of 7000 packets per second, a Maximum Rate of 100000 packets per second, a Drop Period of 300 seconds, and an action of Random. This means the first threshold, 5000 pps, is used to trigger alarm behavior, while the second threshold, 7000 pps, activates the configured mitigation action. Since the selected action is Random, packets are randomly dropped when the TCP rate reaches the activate threshold.

Versa documentation shows that DoS policies can match traffic using source, destination, service, application, schedule, IP version, DSCP, and other conditions, and that a DoS policy can set either an aggregate or classified DoS profile. It also documents that DoS policies support enforcement actions and logging through LEF profiles for DoS events. Therefore, 7000 pps does not merely generate an alarm, and it does not mean complete dropping. Complete dropping is not selected in the exhibit.

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.''
