Symmetric Forwarding is the correct Versa SD-WAN feature for ensuring that return traffic between SD-WAN branches follows the same SD-WAN path on which the forward traffic was received. Versa documentation for SD-WAN traffic steering describes Symmetric forwarding as the option that specifies the path for reverse-direction traffic, meaning whether traffic returning from the destination branch to the originating branch should be sent on the same path on which it arrived. It further states that enabling symmetric traffic forwarding determines the reverse path for traffic returning from the destination branch to the originating branch.

This is different from Symmetric Routing, which is a routing design goal or behavior, not the Versa SD-WAN forwarding-profile feature named in the product documentation. Equal-Cost Multipath can distribute flows across equal-cost routes, but it does not specifically guarantee that both directions of the same SD-WAN session use the same path. Packet Striping is used to split or distribute packets across multiple links for performance, not to enforce bidirectional path symmetry. Therefore, the verified Versa feature to enable is Symmetric Forwarding.

The correct answer is A. In Versa SD-WAN application steering, SaaS or cloud-path selection can use monitoring and DNS-based behavior to determine the best path for an application. For real-time applications such as voice, session stability is often more important than aggressively moving active flows after every path-score change. Session pinning to DNS path is the forwarding-profile behavior that keeps a session associated with the path selected when the DNS/application path decision was made.

This matters because voice and collaboration applications can be sensitive to path changes, packet reordering, and jitter. Pinning prevents active sessions from being unnecessarily moved mid-flow as SaaS monitoring scores change, while still allowing new sessions to take advantage of newer path decisions.

Packet striping is used to distribute packets across multiple circuits and can create reordering concerns for some applications. Symmetric forwarding controls reverse-path behavior rather than DNS-based session stability. Random packet drop is a DoS mitigation action, not a SaaS path-selection feature. Therefore, the best answer is Session pinning to DNS path.

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 LOCAL_PREF. In BGP, the Local Preference attribute is used inside an autonomous system to influence which exit path is preferred for outbound traffic. In this scenario, the Versa Secure SD-WAN CPE receives routes from two upstream service providers, SP1 and SP2. To prefer routes learned from AS 64515 over routes learned from AS 64519, you would apply a BGP import or route policy that assigns a higher local preference to routes received from SP1. Versa SD-WAN design guidance shows this exact routing concept: an import policy can manipulate the Local-Pref attribute to prefer one advertised route path over another. The Versa output examples also display ''Local Preference'' as a BGP route attribute used in route selection.

MULTI_EXIT_DISC, or MED, is generally used to influence how a neighboring AS enters your AS, not how your CPE prefers routes learned from different upstreams. ORIGIN is part of BGP best-path selection but is not normally the administrative tool used to prefer one provider. NEXT_HOP identifies the next-hop address and does not directly define route preference.

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.
