Comprehensive and Detailed 150 to 250 words of Explanation From Versa Networks SDWAN Topics:
The correct answers are B and D . In the exhibit, Enable Auto Switchover is not selected. However, the Failover Timeout value is configured as 300 seconds . Versa Director HA documentation states that the Failover Timeout is the timeout period before the standby Director node can promote itself to become the active Director node. Therefore, if the active or primary Director fails, the backup Director can automatically assume the active role after the failover condition and timeout are met.
The important distinction is that Auto Switchover controls revertive behavior after recovery, not the initial standby takeover during failure. Versa documentation explains that Director HA is non-revertive by default.
This means that when the designated master or primary Director comes back online after recovery, it is not automatically promoted back to active unless automatic switchover is enabled. To make the designated active Director automatically reclaim the active state after recovery, Enable Auto Switchover must be selected and the Auto Switchover Timeout must expire.

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 A . Versa's handy troubleshooting CLI command reference lists show system package- info as the command used to view information about the VOS software image running on the CPE .
This command is useful before upgrade planning because it confirms the installed software package and helps validate whether the device is on the expected release. Administrators can compare the running version against the target upgrade image, verify upgrade prerequisites, and ensure that branch and Controller releases are compatible with required features such as internet speed testing, SD-WAN policy behavior, or security services.
show system uptime only tells how long the system has been running. show interfaces brief provides operational and administrative interface status, MAC address, tenant, VRF, and IP address information. show class-of-services interfaces brief helps troubleshoot QoS or shaping behavior. None of those commands directly identifies the VOS software package. Therefore, for checking the running image before an upgrade, the correct command is show system package-info.

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.

In the exhibit, the Add Associate Interface/Network window has Interface selected, and the interface name is set to vni-0/0 . The DSCP rewrite option is not available because rewrite behavior is intended to be applied at the network association level for the WAN network, not directly while associating only the physical
/logical interface. For WAN-facing CoS, the scheduler and shaping parameters can be attached to an interface, but DSCP rewrite policies are applied to remark traffic as it exits through a network context.
Versa SD-WAN design documentation explains that QoS rewrite rules rewrite packet QoS attributes as packets leave the VOS device, and that rewrite rules can modify IEEE 802.1p bits, IPv4 TOS/DSCP bits, and IPv6 traffic class bits. It also explains that a rewrite policy is commonly applied on a WAN network to remark traffic based on the forwarding class and loss priority assigned by QoS or App QoS policies. In the design example, Versa explicitly describes applying a QoS propagation or rewrite policy on the MPLS WAN network to remark traffic to a DSCP value. Therefore, the issue is the association type: it is set to Interface, not Network.
