57. Frage
Examine the exhibit below.
You are configuring Class of Service on a WAN-facing network interface, and you want to perform DSCP rewrite on the packets that are forwarded to the WAN.
However, you are not able to turn on DSCP rewrite.
Referring to the exhibit, what is the cause of this issue?
Antwort: B
Begründung:
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.
58. Frage
A branch uses a template variable for the WAN VLAN ID. During deployment, Branch-A receives VLAN
100 and Branch-B receives VLAN 200 from device bind data while using the same template. Which statement is correct?
Antwort: A
Begründung:
The correct answer is A . Versa template-based provisioning is designed to separate common configuration from site-specific values. A device template can define common interface, service, routing, and SD-WAN behavior, while variables and device bind data provide unique values for each appliance. This allows the same template to be reused across many branches while assigning different WAN IP addresses, gateways, VLAN IDs, circuit names, or other per-site parameters during onboarding.
In this scenario, Branch-A and Branch-B use the same template but receive different WAN VLAN IDs from bind data. That is normal and expected in a scalable SD-WAN deployment. Without variables, administrators would need to create a separate template for every site, which would be operationally inefficient and increase configuration drift.
The Controller does not automatically rewrite VLAN IDs after IPsec comes up; VLAN IDs must be part of the generated device configuration. It is also not required to duplicate the device template for each branch. The correct Versa design is reusable templates plus unique bind-data values.
59. 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: B
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.
60. Frage
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?
Antwort: C
Begründung:
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.
61. Frage
Which two statements are true about templates? (Choose two.)
Antwort: A,B
Begründung:
The correct answers are C and D . Versa templates are designed to reuse common configuration while still allowing per-device customization. Template variables allow the same template to be deployed to multiple appliances while using device-specific values such as addresses, VLAN IDs, DHCP information, or other bind-data values. Versa documentation for deploying templates describes assigning values to variables contained in a main template that are specific to the device. This makes option C correct.
Option D is also correct because Versa workflows are used to create templates for VOS device configuration.
Versa documentation states that workflows are used to create templates to configure VOS devices, and also to create templates for application steering, spoke groups, and service chains.
Option A is not correct in the normal Versa Director onboarding model because a group of devices is associated with one staging template and one post-staging template, rather than multiple device templates being stacked per appliance. Option B is also incorrect because service templates are optional reusable service-specific fragments. Versa documentation states that service templates can be used by multiple device templates and device groups, but it does not require every appliance to have one.
