The correct answer is A. Versa throughput troubleshooting documentation includes a specific section titled Check that Packets Are not Dropped by CoS. It states that if a CoS shaper or rate limiter is configured on the VOS device, it may drop packets when traffic exceeds the configured shaping rate. To check whether CoS is dropping packets, Versa recommends commands including show class-of-services interfaces brief and show class-of-services interfaces detail interface-name.

The detailed interface output displays traffic statistics such as TX packets, TX packets dropped, TX bytes, TX bytes dropped, and per-traffic-class drops. This is exactly the evidence needed to confirm whether shaping or QoS enforcement is causing the observed loss.

show alarms last-n 10 may reveal major events but will not provide per-interface CoS drop counters. show system uptime only indicates how long the system has been running. show cgnat tenants is relevant for NAT state and tenant CGNAT resources, not QoS drops.

The correct answers are A, B, and E. Versa Operating System, or VOS, is the software platform used for Versa SD-WAN branch and headend functions. Versa troubleshooting documentation explicitly refers to common runtime state across SD-WAN Controller, branch, and hub devices, confirming that VOS is used for Controller and branch-style SD-WAN roles. Versa monitoring documentation also lists SD-WAN branches, SD-WAN Controller nodes, SD-WAN hubs, vCPEs, and uCPEs as assets that are monitored and managed in Versa Director, which aligns with VOS being used as a branch/edge and controller platform.

VOS can also act as a uCPE platform. Versa documentation includes procedures to configure uCPE on a VOS device, showing that VOS can host or support uCPE deployment use cases.

The originally provided answer A, C, D is not correct. A Log Collector or log forwarder function belongs to the Versa Analytics architecture, not the VOS branch role; Versa's design guide states that the log forwarder is part of the Versa Analytics node or can run as a standalone log-forwarder server. A Zookeeper arbiter is also not a standard VOS SD-WAN device role in this context.

The correct answer is C. Versa documentation states that for Releases 22.1.3 and later, the speed test factors in network latency to derive results. In these releases, the speed test is performed in three stages: a ping test, an upload test, and a download test. The ping test calculates link latency, and the speed test uses that latency data while performing the upload and download portions.

The same documentation notes that the speed test can measure bandwidth speeds up to 1 Gbps, with actual measurement depending on factors such as in-path shapers and latency. It also states that the test may use up to 45 MB of data per upload or download in the best case and 90 MB for a complete test.

Older releases behave differently. For Releases 21.2 and earlier, the speed test is performed in two stages: upload and download. Therefore, because the question specifically states Release 22.1.3 on both client and server, the correct sequence is ping, upload, and download.

The correct answer is B. Versa documentation describes checking for asymmetrical SD-WAN paths when troubleshooting bandwidth and throughput issues. It gives the example of traffic being transmitted on one transport network and returning on another transport network that has different bandwidth. To check whether traffic is traversing an asymmetrical SD-WAN path, Versa recommends using show orgs org organization-name sessions sdwan brief.

In that output, the key fields are RX WAN CKT and TX WAN CKT. If the SD-WAN paths are symmetrical, the circuits shown in the RX and TX WAN circuit fields must be the same on the local and remote sites. If traffic goes out over Internet and returns over MPLS, throughput may differ depending on the bandwidth and quality of each circuit.

Source and destination zones are security-policy concepts, while BGP local preference and MED are routing attributes. Tenant ID and VSN ID identify context, but they do not directly prove directional WAN-circuit asymmetry.

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.''
