Versa Networks Versa Certified SD-WAN Specialist (VNX300) Sample Questions (Q17-Q22):

NEW QUESTION # 17
A branch device has completed Stage 3 onboarding. Which set of tunnels or sessions should exist after the device becomes fully operational in the customer SD-WAN network?

A. GRE-only tunnels between all branches without IPsec
B. IKE and IPsec sessions between the branch and Controller, and VXLAN and ESP sessions between branches
C. Only an HTTPS session between the branch and Director
D. Only a BGP session between the branch and Analytics

Answer: B

Explanation:
The correct answer is A . In Versa Secure SD-WAN onboarding, the branch moves through three staging phases before becoming fully operational. Versa documentation states that in Stage 3 , Versa Director pushes the stage-three configuration to the branch device over the IKE session and reboots the branch. After this stage, the branch becomes fully operational and is part of the customer SD-WAN network. At this point, IKE and IPsec sessions are created between the branch and Controller , and VXLAN and ESP sessions are created between branch to branch .
This distinction is important because the Controller connection is used for SD-WAN control-plane functions, while branch-to-branch overlay communication uses tunnel encapsulation for data forwarding. The documentation also notes that branch-to-branch ESP is maintained using a lightweight DH key-pair proprietary protocol.
Options B, C, and D are incorrect. HTTPS to Director alone does not represent the complete SD-WAN operational tunnel state. BGP to Analytics is not the required operational tunnel set. GRE-only tunnels without IPsec do not match the Versa Stage 3 SD-WAN tunnel behavior described in the staging documentation.

NEW QUESTION # 18
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?

A. CGNAT and DNS configuration
B. SNMP community and syslog server
C. OSPF area ID and BGP MED
D. VRRP priority and DHCP lease time

Answer: A

Explanation:
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.

NEW QUESTION # 19
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?

A. The Policy Configuration is missing an additional policy with the subnets swapped.
B. The Routing Instance should be changed to global.
C. A precedence higher than 0 needs to be set.
D. The Tunnel Routing Instance is incorrect.

Answer: D

Explanation:
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.

NEW QUESTION # 20
While troubleshooting the SD-WAN data path, you run show vsf tunnel access-circuits ... detail and see the following encapsulation chain: VMLH, MPLS-over-GRE, IPsec-ESP, and VXLAN. What does this output primarily confirm?

A. The branch is using only plain-text GRE without encryption.
B. The traffic is being bridged without SD-WAN encapsulation.
C. The traffic is bypassing the VOS data plane.
D. The branch has created an SD-WAN tunnel encapsulation stack for overlay forwarding.

Answer: D

Explanation:
The correct answer is B . Versa's SD-WAN data-path troubleshooting documentation shows that show vsf tunnel access-circuits ... detail can display the access-circuit state and encapsulation chain used for tunnel forwarding. In the example, the output lists multiple encapsulations, including VMLH , MPLS-over-GRE , IPsec-ESP , and VXLAN . It also shows transport details such as source IP, destination IP, UDP transport, tunnel MTU, SPI values, and SLA state.
This confirms that the VOS data plane has built the SD-WAN tunnel encapsulation stack required to forward overlay traffic across the underlay. IPsec-ESP in the chain indicates encrypted tunnel handling, while VXLAN and other encapsulation components are part of the SD-WAN overlay forwarding structure.
The output does not indicate simple bridging, plain-text-only GRE, or bypass of the VOS data plane.
Instead, it proves that the packet path is being processed through the VOS tunnel forwarding framework and that the administrator is looking at the SD-WAN access-circuit tunnel state.

NEW QUESTION # 21
A branch user reports poor throughput over an SD-WAN tunnel. The command show interfaces detail vni-0/0 shows the interface is operating at half-duplex / 100 Mbps , although the circuit is expected to run at 1 Gbps full duplex. What is the most likely cause?

A. There is an underlay link speed or duplex mismatch.
B. SD-WAN SLA probing is disabled.
C. VXLAN encapsulation is missing on the overlay.
D. The Controller is not advertising branch routes.

Answer: A

Explanation:
The correct answer is C . Versa's bandwidth and throughput troubleshooting documentation specifically instructs administrators to check link speed and half-duplex conditions with the command show interfaces detail interface-name. The example output shows an interface operating at half-duplex / 100 Mbps , and the documentation states that the interface should not be in half-duplex mode and that 100 Mbps was incorrect in that scenario.
A duplex mismatch or incorrect negotiated speed can severely reduce effective throughput, cause collisions or retransmissions, and make SD-WAN overlay performance appear poor even when the overlay itself is functioning. Versa recommends fixing half-duplex and link-speed issues by correcting the configuration on the device to which the VOS device is connected and checking the ISP-side transmission mode, such as auto
/auto.
SLA probing, Controller route advertisement, and VXLAN encapsulation may affect SD-WAN path selection or tunnel formation, but the evidence in the question directly points to a physical or underlay Ethernet negotiation problem.
