Answer : C

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.

Answer : B

The correct answer is B. Versa branch lifecycle notifications are generated at different stages of onboarding. The first notification indicates that the branch connected using factory-default configuration. After that notification, Versa Director pushes the staging configuration to the branch and requests a reboot. After rebooting with staging configuration, the branch should connect again to the Controller, and a later branch-connect notification should appear.

If this later staged connection notification does not appear, Versa's troubleshooting guidance says to debug either the data path or IPsec connectivity from the branch to the Controller. This makes sense because the branch must have working transport reachability and IKE/IPsec establishment toward the Controller before it can continue the SD-WAN lifecycle.

Analytics disk usage, LDAP authentication, and URL filtering are not part of the branch staging control path. They may affect monitoring, user identity, or security inspection after the site is operational, but they do not explain why the branch stops after the initial factory-default onboarding notification.

Answer : B

The correct answer is B. The DoS profile in the exhibit is a Classified Profile using Source IP Only as the classification key. For TCP flood protection, the profile is enabled and shows an Alarm Rate of 5000 packets per second, an Activate Rate of 7000 packets per second, a Maximum Rate of 100000 packets per second, a Drop Period of 300 seconds, and an action of Random. This means the first threshold, 5000 pps, is used to trigger alarm behavior, while the second threshold, 7000 pps, activates the configured mitigation action. Since the selected action is Random, packets are randomly dropped when the TCP rate reaches the activate threshold.

Versa documentation shows that DoS policies can match traffic using source, destination, service, application, schedule, IP version, DSCP, and other conditions, and that a DoS policy can set either an aggregate or classified DoS profile. It also documents that DoS policies support enforcement actions and logging through LEF profiles for DoS events. Therefore, 7000 pps does not merely generate an alarm, and it does not mean complete dropping. Complete dropping is not selected in the exhibit.

Answer : A

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.

Answer : A, B

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.
