VNX301 Practice Questions

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 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 B and D . In the exhibit, the Next-Hop Selection Method is configured as Load Balance , and both INET and INET-2 have the same next-hop priority value of 1 . Versa SD-WAN guidance states that load balancing between WAN paths is achieved by configuring at least two circuits with equal priority. Therefore, when both INET and INET-2 satisfy the SLA requirements, sessions can be load-balanced across those two internet circuits.

Option D is also correct because the exhibit shows SLA Violation Action: Forward . This means that if no next hop is SLA-compliant, the VOS device is still allowed to forward traffic instead of dropping it. This behavior is consistent with Versa SD-WAN traffic-steering concepts, where forwarding profiles define circuit or path priorities, connection methods, load-balancing behavior, and SLA handling for traffic that matches an SD-WAN policy.

Option A is incorrect because the exhibit does not use the Automatic next-hop selection method. Versa’s performance-based SaaS optimization uses monitoring metrics to select the best path when configured for automatic/performance-based selection, but this exhibit shows Load Balance instead. Option C is not the best answer because LTE has lower priority 2 and would be considered only after the higher-priority INET and INET-2 paths are unavailable or unusable, not merely when one INET circuit fails.

The correct answers are C and D . Versa templates are designed to reuse common configuration while still allowing per-device customization. Template variables allow the same template to be deployed to multiple appliances while using device-specific values such as addresses, VLAN IDs, DHCP information, or other bind-data values. Versa documentation for deploying templates describes assigning values to variables contained in a main template that are specific to the device. This makes option C correct.

Option D is also correct because Versa workflows are used to create templates for VOS device configuration. Versa documentation states that workflows are used to create templates to configure VOS devices, and also to create templates for application steering, spoke groups, and service chains.

Option A is not correct in the normal Versa Director onboarding model because a group of devices is associated with one staging template and one post-staging template, rather than multiple device templates being stacked per appliance. Option B is also incorrect because service templates are optional reusable service-specific fragments. Versa documentation states that service templates can be used by multiple device templates and device groups, but it does not require every appliance to have one.
