21. Frage
A branch device is powered on with factory-default staging configuration. The device establishes an IKE session to the staging server and receives an IP address, but it does not proceed to establish an IKE session with the Versa Controller. Which staging phase is failing?
Antwort: B
Begründung:
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.
22. Frage
Examine the exhibit below.
Which two statements correctly explain the routing shown in the exhibit. (Choose two.)
Antwort: B,C
Begründung:
The correct answers are A and C . The route table shown in the Versa SD-WAN design documentation includes a default route, 0.0.0.0/0 , with next hop 169.254.0.2 and exit interface tvi-0/603.0 . A default route is used when no more specific route exists in the routing table, so any unknown IPv4 unicast destination will follow that active default route through the tvi-0/603 interface. This directly supports option C.
The same design context describes local or central internet breakout, where Director workflows create TVI- based connectivity for breakout or gateway-style forwarding. In Versa SD-WAN, TVI interfaces are commonly used as internal virtual tunnel interfaces between routing instances, such as between a tenant LAN VR and a transport or breakout VR. The documentation also describes virtual TVI interface pairs being created by Director workflows between VRs for gateway routing use cases. Therefore, option A is also correct: tvi-0/603 is paired with another interface in another VR to support the default-route forwarding path.
The IP address is not shown as misconfigured; 169.254.x.x addressing is commonly used for point-to- point internal TVI links. The route is also not a blackhole route, because it has an active next hop and an exit interface.
23. Frage
During branch onboarding, you need to verify whether the Controller has sent branch-connect and branch- disconnect notifications to Versa Director. Which CLI command should be used?
Antwort: D
Begründung:
The correct answer is A . Versa troubleshooting documentation states that after a branch device successfully establishes an IPsec connection to the Controller node, the Controller sends a notification to the Director node. To display the details of this notification, the documentation instructs administrators to issue the show alarms CLI command. It also provides examples using show alarms | match branchd | match br101 to view branch-connect and branch-disconnect events.
These alarm entries are valuable during onboarding because they show whether the branch reached the Controller, whether staging progressed, and whether the branch later disconnected. For example, branch lifecycle notifications include factory-default connection, staged connection, Stage 3 connection with WAN IP addresses, and branch disconnect events.
show system storage is useful for disk usage, show interfaces detail helps with link state, speed, duplex, and interface counters, and show cgnat acl info is used for CGNAT matching. None of those commands directly confirms branch lifecycle notifications between Controller and Director.
24. Frage
Examine the exhibit below.
Spoke1 and Spoke2 are part of Spoke-to-Hub-Only spoke group, the hub is advertising a default route to both the spokes.
Referring to the exhibit, which statement is true?
Antwort: A
Begründung:
In Versa SD-WAN, a Spoke-to-Hub-Only topology is specifically designed for deployments where spoke branches communicate only with hub resources and not with other spokes. Versa's SD-WAN design documentation states that in a spoke-to-hub-only topology, the default behavior is that only hub routes are advertised, and spoke routes are not re-advertised by the hub branch. It also explains that this topology is used when spokes do not have to communicate with each other.
Even though the hub in the exhibit advertises a default route, that does not change the topology behavior into spoke-to-spoke communication. The default route can attract unknown traffic from the spokes toward the hub, but the Spoke-to-Hub-Only policy prevents the spoke prefixes from being redistributed or imported in a way that allows spoke-to-spoke reachability. Versa documentation further shows that spoke routes are filtered using BGP communities and import policies, and that the spoke route table contains only destinations behind the hubs, not other spoke routes.
25. Frage
Examine the exhibit below.
You are configuring an IPsec tunnel towards a non-SD-WAN site over the INETTransport-VR. The site IP address is 10.1.1.1. This tunnel is for traffic between the 192.168.100.0/24 and the 192.168.200.0/24 LAN networks. The tunnel does not establish.
Referring to the exhibit, which statement is correct?
Antwort: C
Begründung:
The correct answer is A . The exhibit shows that the IPsec VPN is being configured with Tunnel Routing Instance: XIAN-Control-VR . However, the question states that the tunnel is toward a non-SD-WAN site over the INET-Transport-VR . For a site-to-site IPsec tunnel, the tunnel routing instance must match the routing instance used to reach the peer public IP address. In this case, the remote non-SD-WAN peer is
10.1.1.1 , and the intended underlay transport is INET-Transport-VR , not the Control VR.
Versa troubleshooting documentation explains that routing instances are used to define where traffic is sourced and forwarded. For example, configuration examples select routing instances when enabling services or initiating tests, and traffic must use the correct WAN or transport routing instance to reach the remote endpoint. Versa branch troubleshooting also emphasizes that after transport connectivity is available, the branch establishes IKE-based IPsec connectivity; if that connectivity fails, the IPsec-related interface remains down.
Changing the routing instance to global would not be correct because the intended path is specifically INET-Transport-VR. A higher precedence value is not required to establish the tunnel. The policy selector shown already defines local-to-remote interesting traffic, and the key failure is the incorrect tunnel routing instance.
