質問 # 20
Examine the exhibit below.
As an administrator of a Versa Secure SD-WAN deployment, you are asked to find the current bandwidth of each WAN circuit used for SD-WAN connectivity in a branch, but Versa Director is not displaying any information for the WAN circuits. In this scenario, what should be done to get the graph populated for all WAN circuits?
正解：A
解説：
The correct answer is B . In the exhibit, Versa Director shows multiple branch interfaces and a Live Data column. To populate the bandwidth graph with current real-time statistics for all WAN circuits, Live Data must be selected for each WAN circuit that should be monitored. Versa documentation states that from a Director node, administrators can monitor VOS devices, provider organizations, tenants, events, and alarms. It also explains that Versa Director, together with Versa Analytics, can poll VOS devices in real time to provide visibility into what is happening on those devices and to assist with troubleshooting.
Because the requirement is to find the current bandwidth of each WAN circuit, simply refreshing the page is not enough. Refreshing only reloads the dashboard; it does not enable real-time polling for interfaces that are not selected. Selecting Live Data only for MPLS circuits would populate only MPLS- related data and would not satisfy the requirement for all WAN circuits. Unselecting and reselecting only the INET circuit affects only that one circuit. Therefore, the correct operational step is to enable Live Data for all WAN circuits shown in the branch interface dashboard.
質問 # 21
Examine the exhibit below.
Referring to the exhibit, which two statements are correct? (Choose two.)
正解：A、B
解説：
The correct answers are A and B . In the exhibit, the LAN interface shows a fixed VLAN ID value of 100 .
Because this value is directly configured in the template rather than represented as a per-device variable, every branch that uses this template will receive the same LAN VLAN ID. This supports option A. Versa configuration examples show that VLAN-tagged interfaces are created by defining logical units with a vlan- id, and organizations then use those tagged interfaces for traffic identification and routing services.
For the MPLS WAN network , the VLAN ID field is shown as a variable or bind-data style value rather than a fixed number. This allows each branch device to receive a different MPLS VLAN ID during onboarding, depending on the branch-specific values supplied in the workflow or device bind data. Therefore, branches can have separate VLAN IDs on the MPLS WAN transport, which supports option B. Versa SD-WAN troubleshooting output also shows WAN interfaces as logical VNI subinterfaces, such as vni-0/1.0 and vni-0/2.
0, mapped to SD-WAN transport networks like INET and MPLS.
Option C is incorrect because an INET interface can be untagged, commonly represented with VLAN ID 0. Option D is incorrect because the MPLS VLAN field is intentionally parameterized, not incorrectly configured.
質問 # 22
A branch has Direct Internet Access enabled. Users can resolve DNS, but application traffic fails. You find that the internet speed test also fails to fetch the server list. Which two configurations should be checked first?
正解：C
解説：
The correct answer is A . Versa documentation for internet speed tests states that before running an internet speed test, administrators must verify WAN internet connectivity and verify that CGNAT is configured on the provider organization. It also states that administrators should verify that they can retrieve the list of predeployed internet speed-test servers. If an error occurs while fetching the server list, the documentation instructs administrators to check the CGNAT and DNS configurations and then click Fetch Server List again.
This aligns with the scenario because DNS resolution and internet breakout depend on correct DNS reachability, NAT translation, and routing through the internet-facing transport. Even if DNS appears partially functional, CGNAT misconfiguration can still prevent application or HTTP test traffic from completing properly.
OSPF, BGP MED, SNMP, syslog, VRRP, and DHCP may be important in other designs, but they are not the first items Versa identifies for a failed internet speed-test server-list fetch in a DIA context.
質問 # 23
A branch using DIA with CGNAT reports that new internet sessions intermittently fail. CGNAT pool counters show increasing out-of-ports errors, while out-of-address errors remain zero. What is the most likely problem?
正解：A
解説：
The correct answer is A . Versa CGNAT troubleshooting documentation includes per-pool and resource counters that show allocation behavior and failures. The counters include values such as bindings allocated, bindings freed, allocation failures, out-of-address errors, and out-of-ports errors. It also shows that CGNAT source-port resources are divided and distributed to worker threads by Versa RFD/RFM, and that allocated source-port ranges can be viewed using show rfm table src-port allocated.
If out-of-ports errors increase while out-of-address errors remain zero, the pool still has usable translated IP addresses, but the available port resource for NAT bindings is exhausted. This commonly occurs when too many concurrent sessions share a limited public IP or source-port range. The corrective action would be to expand the NAT resource, add more public translated IPs, adjust port allocation, or reduce excessive session usage.
A missing NAT IP pool would more likely produce out-of-address problems. A wrong zone match might prevent translation entirely, and OSPF in the LAN VR is unrelated to CGNAT port-resource exhaustion.
質問 # 24
You are troubleshooting a branch that cannot form SD-WAN overlay tunnels. The branch has WAN interfaces up, but you suspect remote endpoint objects were not learned. Which VSM command should you use to verify whether remote site objects were learned from BGP or from configuration?
正解：D
解説：
The correct answer is A . Versa data-path troubleshooting documentation gives a specific VSM control-plane workflow for checking SD-WAN tunnel objects. After connecting to the VSM daemon, administrators can use show vsm p2mp local-tunnel-sites 0 to inspect local site objects. To check whether remote site objects were learned from BGP or from configuration , Versa instructs administrators to issue show vsm p2mp tunnel-remote-endpoint tenant < tenant-id > on the VSM control plane.
This command is highly relevant when local WAN interfaces are operational, but overlay tunnel formation is incomplete. It shows remote endpoints such as Controllers, hubs, or branches, along with site type, site name, branch ID, tenant ID, remote WAN link information, and tunnel state-related fields.
show interfaces brief confirms interface state and IP addresses, but it does not show learned remote SD- WAN endpoint objects. CGNAT summary is unrelated to tunnel endpoint learning. System storage is useful for disk checks, but not for SD-WAN overlay endpoint troubleshooting.
