NEW QUESTION # 23
You configured Direct Internet Access on your Versa branches using the workflow template. Which statement is true in this scenario?
- A. You must define a CGNAT address pool and rule, and associate the rule with the LAN interface.
- B. DIA configured in a workflow automatically creates a CGNAT pool and rule, and associates it with the internet-facing network.
- C. CGNAT is not required when you configure DIA services.
- D. You must define a CGNAT address pool and rule, and associate the rule with the internet-facing network.
Answer: B
Explanation:
The correct answer is C . In Versa Secure SD-WAN, Direct Internet Access, or DIA, provides local internet breakout from the branch rather than backhauling internet-bound traffic through a hub. Versa design documentation explains that the DIA architecture creates an internal connection between the tenant VRF and the WAN transport VR and uses CGNAT to translate internet-bound LAN traffic to the public IP address associated with the WAN transport interface. It specifically states that the main DIA components include the CGNAT function for translating internet-bound traffic and that DIA is configured using Director Workflows when configuring tunnels.
When the workflow template is used and the DIA option is selected for the internet breakout tunnel, Director automatically builds the required DIA infrastructure, including the NAPT/CGNAT configuration associated with the internet-facing transport network. This is why manual creation of the CGNAT pool and rule is not required in the workflow-based method. Option A describes a manual configuration approach, not the workflow-generated behavior. Option B is incorrect because NAT must be associated with the internet-facing breakout path, not simply the LAN interface. Option D is incorrect because DIA normally requires address translation for LAN users accessing the public internet.
NEW QUESTION # 24
Examine the exhibit below.
Which two statements correctly explain the routing shown in the exhibit. (Choose two.)
- A. The tvi-0/603 interface is a stub interface for black holing an unknown IP unicast destination.
- B. The IP address configured on the tvi-0-603 interface its misconfigured by the template.
- C. The tvi-0/603 interface is paired with an interface in another VR for the default route.
- D. Any unknown IP unicast destination will use the tvi-0/603 interface for its exit.
Answer: C,D
Explanation:
The correct answers are A and C . The route table shown in the Versa SD-WAN design documentation includes a default route, 0.0.0.0/0 , with next hop 169.254.0.2 and exit interface tvi-0/603.0 . A default route is used when no more specific route exists in the routing table, so any unknown IPv4 unicast destination will follow that active default route through the tvi-0/603 interface. This directly supports option C.
The same design context describes local or central internet breakout, where Director workflows create TVI- based connectivity for breakout or gateway-style forwarding. In Versa SD-WAN, TVI interfaces are commonly used as internal virtual tunnel interfaces between routing instances, such as between a tenant LAN VR and a transport or breakout VR. The documentation also describes virtual TVI interface pairs being created by Director workflows between VRs for gateway routing use cases. Therefore, option A is also correct: tvi-0/603 is paired with another interface in another VR to support the default-route forwarding path.
The IP address is not shown as misconfigured; 169.254.x.x addressing is commonly used for point-to- point internal TVI links. The route is also not a blackhole route, because it has an active next hop and an exit interface.
NEW QUESTION # 25
Examine the exhibit below.
The exhibit shows a device group created for a new group of hubs. The device template called "BMBF- TEMPLATE" has an Address object called "Server". A network administrator creates the Class of Service Template called "Ship-CoS-IT" that has an Address object with the same name. Then it tries to onboard a new device to this device group.
Which statement is true about the configuration that this device will have?
- A. The device configuration will have the Address object that was created last.
- B. The device configuration commit will fail.
- C. The device configuration will automatically create two copies of the same Address object.
- D. The device configuration will have the version of the Address object in the QoS template.
Answer: D
Explanation:
The correct answer is D . In the displayed post-staging template association order, the device template BMBF- TEMPLATE is applied before the QoS service template Ship-CoS-IT . Versa documentation explains that device templates, also called post-staging templates, provide the baseline configuration for devices, while service templates are service-specific configurations that can be applied to device configurations. It also states that service templates are associated with device groups and that, in a device group, the administrator can choose the order in which service templates are applied.
Because the QoS template is later in the shown association order, the final merged device configuration uses the Address object definition from the QoS template when the same object name exists in both templates. It does not automatically create two copies of the same Address object, because the object name is the key for the configuration element. It also should not fail merely because the same object name exists in a later template; the merge behavior resolves the effective configuration according to the template order. Therefore, the onboarded hub device receives the Server Address object version from Ship-CoS-IT, the QoS template.
NEW QUESTION # 26
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. SD-WAN SLA probing is disabled.
- B. VXLAN encapsulation is missing on the overlay.
- C. There is an underlay link speed or duplex mismatch.
- D. The Controller is not advertising branch routes.
Answer: C
NEW QUESTION # 27
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. VRRP priority and DHCP lease time
- C. OSPF area ID and BGP MED
- D. SNMP community and syslog server
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 # 28
Which three notification methods does Versa Director allow you to configure for sending system event notifications? (Choose three.)
- A. SMTP
- B. MMS
- C. Kafka
- D. Webhook
- E. SMS
Answer: A,C,D
Explanation:
The correct answers are A, B, and E . Versa Director supports multiple notification and event-publishing mechanisms. For email-style system and alarm notifications, Versa Director supports SMTP configuration.
The Director documentation lists Configure SMTP Notifications and explains that email templates require SMTP notifications to send test emails or operational messages.
Versa Director also supports webhook notifications. The Director GUI overview states that Notification Configuration includes webhook-based notifications for alarms, and the Director documentation includes a dedicated workflow for configuring webhook notifications for alarms.
Kafka is also a supported event-notification method. Versa's Kafka Notifications documentation states that Versa Director can publish event notifications to an Apache Kafka server when events occur on a Director node or a VOS device. It also lists notification topics for device events, Director events, Director task notifications, and object-change event notifications.
MMS is not a Versa Director system event notification method. SMS can be configured for text messaging in some notification contexts, but for the three methods listed for system event notifications in this answer set, the verified options are SMTP, Webhook, and Kafka.
NEW QUESTION # 29
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?
- A. The LAN routing instance is missing OSPF.
- B. The NAT pool has no IP addresses assigned.
- C. The NAT pool has no available source ports left for allocation.
- D. The CGNAT rule is matching the wrong destination zone.
Answer: C
Explanation:
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.
NEW QUESTION # 30
As an administrator, you are migrating your legacy WAN to Versa Secure SD-WAN without changing the underlay network. You need to ensure that, during the migration process, legacy WAN sites are allowed to communicate with SD-WAN branches. Which two steps should be implemented to accomplish this task?
(Choose two.)
- A. Using workflows, configure the Gateway option in the hub template for the underlay links.
- B. Configure an SD-WAN traffic steering policy to advertise the SD-WAN routes.
- C. Apply the Spoke-to-Spoke-Direct topology for the SD-WAN branches.
- D. Configure BGP on the hub underlay links to advertise and receive the prefixes.
Answer: A,D
Explanation:
The correct answers are B and C . During a migration from a legacy WAN, such as MPLS Layer 3 VPN, to Versa Secure SD-WAN, an SD-WAN gateway is used to allow communication between SD-WAN-enabled branches and legacy WAN sites. Versa SD-WAN design guidance states that an SD-WAN gateway allows sites connected to the SD-WAN VPN network to communicate with sites connected to a legacy MPLS VPN network. It also explains that this gateway facilitates route exchange between the MPLS underlay network and the SD-WAN VPN network, typically using a dynamic routing protocol such as BGP.
For this design, the hub or gateway must be configured with the Gateway option for the underlay transport so it can act as the interconnect point between the legacy and SD-WAN domains. Versa documentation further describes configuring a BGP peering session on the MPLS transport VR of the gateway to exchange routes from the MPLS provider to the SD-WAN network, and notes that Director Workflows can automate this configuration. Spoke-to-Spoke-Direct is not sufficient for legacy interconnect, and SD-WAN traffic steering policies do not advertise routes.
NEW QUESTION # 31
Which two statements are true about templates? (Choose two.)
- A. You can use a Workflow Template to create new device templates.
- B. You can use variables in a template to allow devices to have unique values.
- C. You must have at least one service template per appliance.
- D. You can have more than one device template per appliance.
Answer: A,B
Explanation:
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.
NEW QUESTION # 32
What are two features of the Stateful Firewall service in the Versa Operating System? (Choose two.)
- A. Application-Level Gateways (ALG)
- B. DoS protection
- C. Intrusion Detection System
- D. URL filtering
Answer: A,B
Explanation:
The correct answers are A and D . Versa stateful firewall service includes classic firewall functions that track sessions and enforce traffic policy, and it can work with DoS policy enforcement. Versa's CLI guide includes Configuring DoS policies under the security configuration area, where DoS rules can match on source, destination, services, applications, URL category, IP version, DSCP, TTL, EtherType, and other packet or session attributes, and can then apply aggregate or classified DoS profiles. This validates DoS protection as a stateful firewall/security service capability.
Application-Level Gateways, or ALGs , are also associated with stateful firewall/NAT behavior because they inspect and assist protocol handling for applications that embed addressing or dynamic port information inside the payload or control channel. This is part of traditional stateful firewall service behavior rather than UTM content inspection.
NEW QUESTION # 33
Which two statements are true about the differences between a stateful firewall and a next-generation firewall (NGFW) in a Versa solution? (Choose two.)
- A. Stateful firewalls cannot log information into Versa Analytics; only NGFW can send logs into Versa Analytics.
- B. Stateful firewalls are available in all of Versa's licensing offerings, while NGFW requires specific licensing to operate.
- C. Stateful firewalls can run with any version of VOS, while NGFW requires specific VOS images to operate.
- D. Stateful firewalls focus on examining information in L2, L3, and L4 fields, while NGFW can examine all fields of a packet, including L7.
Answer: B,D
Explanation:
The correct answers are A and D . A Versa stateful firewall primarily enforces security by tracking connection state and matching packet/session information such as source, destination, zones, services, protocol, and L3/L4 attributes. Versa's CLI configuration guide shows stateful firewall access-policy match options for source and destination addresses, services, IP version, IP flags, DSCP, TTL, and also optional application and URL-category match fields when enhanced services are available.
A Versa NGFW extends this inspection model by adding deeper Layer 7 and UTM capabilities, such as IDS
/IPS, antivirus, URL filtering, file or data filtering, and application-aware enforcement. Versa's SD-WAN design guide specifically describes internet security using the Versa next-generation firewall with unified threat management features, including IDS/IPS and antivirus inspection for DIA traffic. Licensing is also a valid distinction: Versa's SD-WAN licensing overview describes NGFW features as part of solution tiers, so the availability of advanced security functions depends on the licensed tier or subscription
NEW QUESTION # 34
A branch device is stuck after staging. The Controller does not show the expected branch lifecycle notification. Which statement best describes the role of MP-BGP in the provider organization for this process?
- A. MP-BGP is recommended so notifications for relevant branch events are delivered to Versa Director.
- B. MP-BGP is used only between branch LAN routers and user subnets.
- C. MP-BGP replaces IKE and IPsec during branch staging.
- D. MP-BGP is required only for URL filtering category updates.
Answer: A
Explanation:
The correct answer is A . Versa branch troubleshooting documentation states that the provider organization should have MP-BGP configured for SD-WAN deployments so that notifications for all relevant branch events are delivered to the Versa Director node. This is significant during onboarding because branch lifecycle events, such as branch-connect and branch-disconnect, help Director determine where the branch is in the staging process and whether the next configuration push should occur.
MP-BGP does not replace IKE or IPsec. The branch still establishes IKE/IPsec to the staging server or Controller depending on the staging phase. MP-BGP also has nothing to do with URL filtering category updates. While BGP can be used in LAN or WAN routing designs, the specific issue described here concerns provider-organization SD-WAN control-plane event delivery.
Therefore, if branch lifecycle events are not appearing properly, validating provider-organization MP- BGP configuration is part of the correct troubleshooting workflow, especially in addition to checking data-path and IPsec connectivity.
NEW QUESTION # 35
A customer has purchased 10 Versa SD-WAN licenses. In this scenario, which statement is correct?
- A. The customer will be provided 10 Versa SD-WAN CPEs loaded with a Versa SD-WAN license.
- B. The customer's CPE will subjugate to Versa Controller using ZTP; afterward, the licenses and license subscriptions will be managed by Versa Controller.
- C. The customer will be provided 10 Versa SD-WAN soft licenses.
- D. The customer's SD-WAN CPE will subjugate to Versa Director using ZTP; afterward, the license subscriptions will be managed by Versa Director.
Answer: D
Explanation:
The correct answer is C . In Versa Secure SD-WAN, licensing and device management are centralized through Versa Director , not directly through the Controller. During zero-touch provisioning and staging, the branch device is brought under centralized management, and Director pushes the required staging and operational configuration. Versa staging documentation explains that during Stage 2 and Stage 3, Versa Director pushes configuration to the branch device, and after Stage 3 the branch becomes fully operational as part of the customer SD-WAN network.
Versa monitoring documentation also shows that the Director node provides license visibility, specifically stating that the Director monitoring view includes a License pane that displays information about the licenses installed on the VOS devices managed by the Director node. This confirms that license administration is handled from Director, not from the Controller. The Controller is responsible for SD-WAN control-plane functions and tunnel connectivity, but it is not the primary system for managing customer license subscriptions.
Option A is incomplete because the practical operational model is not simply receiving individual soft licenses. Option B incorrectly implies licenses are preloaded on physical CPEs as the key licensing method. Option D is incorrect because ZTP management and license subscription handling are not performed by the Controller.
NEW QUESTION # 36
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. Only a BGP session between the branch and Analytics
- B. GRE-only tunnels between all branches without IPsec
- C. Only an HTTPS session between the branch and Director
- D. IKE and IPsec sessions between the branch and Controller, and VXLAN and ESP sessions between branches
Answer: D
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 # 37
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?
- A. show alarms last-n 10
- B. show system uptime
- C. show cgnat tenants
- D. show class-of-services interfaces detail interface-name
Answer: D
Explanation:
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.
