質問 # 44
You have deployed a group of devices in Versa Director, and the field technicians have performed the onboarding tasks onsite. One of the devices has not finished the onboarding process and does not appear in the Appliances list in Versa Director. The onboarding VPN tunnel from the device to the Controller is up.
Which two actions would help you solve this problem? (Choose two.)
正解：A、B
解説：
The correct answers are A and C . If the onboarding VPN tunnel from the branch device to the Controller is up, the branch has reached at least the initial staging/control connectivity stage. Versa troubleshooting documentation explains that after a branch establishes IPsec connectivity to the Controller, the Controller sends a branch-connect notification to Versa Director. In response, Director pushes staging configuration and continues the onboarding lifecycle. If the expected later notification is not seen, the branch has not completed staging and further onboarding/debug steps are required.
The Tasks list in Versa Director is useful because device deployment and onboarding actions are executed as Director tasks. If template commit, workflow deployment, device claiming, or configuration push fails, the task output can show the error. The Unknown Devices dashboard is also relevant because a device that reaches the Controller but cannot be matched or fully associated with an expected workflow/appliance record may appear as an unknown device awaiting administrative review. The Monitor dashboard is not the best choice because the device is missing from the Appliances list and has not completed onboarding. Resource Pool is related to connector resources, not branch onboarding completion.
質問 # 45
Examine the exhibit below.
You are onboarding the SOLDEU-R2 branch device using the staging script. You cannot get a Versa- Provider-Controller-VR IP address assigned, indicating that the IPsec tunnel to the corrector has not come up.
You verified that the cables have been connected to the correct ports.
What has caused this issue?
正解：C
解説：
The issue is caused by specifying the incorrect WAN port in the staging script. In the exhibit, the SOLDEU- R2 branch is physically connected to the Internet cloud through vni-0/0 , while vni-0/1 is shown as the inter- device link toward SOLDEU-R1. However, the show interfaces brief output shows that the WAN IP address
192.168.122.121/24 has been assigned to vni-0/1.0 , not to the Internet-facing interface. Since the cables are confirmed to be connected correctly, the mismatch must be in the staging script interface selection, not in the cabling.
Versa documentation states that during SD-WAN staging, the branch establishes an IKE session with the Controller, and after that the Controller assigns an IP address to the branch device. Versa troubleshooting guidance also states that after transport connectivity to the Controller is established, the branch forms IKE-based IPsec connectivity, and if this succeeds, the ptvi interface toward the Controller comes up. If IKE/IPsec fails, the ptvi interface remains down. Because the staged WAN IP is placed on the wrong VNI interface, the branch cannot reach the Controller over the intended Internet transport, so the Controller tunnel does not come up.
質問 # 46
A branch has correct underlay speed and no asymmetric SD-WAN paths, but users still report packet loss during large transfers. You suspect QoS shaping is dropping traffic. Which command is most appropriate to verify interface-level CoS drops?
正解：A
解説：
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.
質問 # 47
Examine the CLI output in the exhibit.
You are reviewing the OSPF adjacency on a VOS CPE, and the output is shown in the exhibit. In this scenario, what is the probable cause of the OSPF adjacency issue?
正解：B
解説：
The correct answer is B . The exhibit shows the OSPF neighbor in the exst state, which means Exchange Start . Versa documentation lists the OSPF neighbor state codes and identifies exst as "exchange start," followed by exchange, loading, and full. In normal OSPF adjacency formation, neighbors progress through initialization and two-way communication before they negotiate database exchange. If the neighbor becomes stuck in ExStart or Exchange, a common and highly probable cause is an MTU mismatch between the two OSPF peers. During database description packet negotiation, the peers must agree on parameters that allow LSDB exchange; an MTU mismatch can prevent the adjacency from advancing to Full.
Option A is less likely because an area mismatch usually prevents the neighbor relationship from forming correctly rather than leaving it stuck in ExStart. Option C is also incorrect because the neighbor has already progressed beyond early states, which indicates that bidirectional communication has occurred. Option D is not the best answer because dropping OSPF multicast 224.0.0.5 would typically prevent discovery or keep the adjacency in an earlier state, not specifically in ExStart.
Therefore, the probable cause is an interface MTU mismatch.
質問 # 48
An SD-WAN branch is deployed behind a NAT device. In the VSM local-tunnel-site output, which field or flag indicates that a WAN link is behind NAT?
正解：D
解説：
The correct answer is A . Versa SD-WAN data-path troubleshooting documentation shows the VSM local- tunnel-site output and includes a legend in which BN means Behind NAT . In the WAN local link details, the output also displays a field named WAN lcl link behind NAT , with values such as 1 or 0, and link flags including [ BN CT PT SLA-P ] when the WAN link is behind NAT.
This information is important because NAT status affects how SD-WAN tunnel endpoints are discovered and how public and private transport addresses are represented. The same output includes both public and private WAN link addresses, making it useful for troubleshooting sites behind NAT, stale tunnel endpoints, or incorrect public-address learning.
WAN lcl vrf-id identifies the local transport routing instance ID, not NAT status. Tenant ID identifies the tenant context. Neighbour site type identifies whether the remote endpoint is a Controller, hub, or SD-WAN site. None of those fields specifically confirms whether the local WAN transport is behind NAT.
