NEW QUESTION # 16
A device is being onboarded with two Internet interfaces. Direct Internet Access (DIA) needs to be configured.
In this scenario, which two statements are true? (Choose two.)
- A. Both Internet interfaces can be selected for DIA in workflows.
- B. Each underlay interface belongs to its own VR instance.
- C. All underlay interfaces belong to the same VR instance.
- D. Only one Internet interface can be selected for DIA in workflows.
Answer: A,B
Explanation:
In a scenario where a device is onboarded with two Internet interfaces and Direct Internet Access (DIA) is being configured, the following statements hold true:
* Each underlay interface belongs to its own VR instance (Answer B): Typically, in Versa SD-WAN configurations, each underlay interface is assigned to its own virtual router (VR) instance. This approach allows for greater flexibility and isolation in managing routing and security policies specific to each interface. It supports independent operation and control, which is crucial for optimizing performance and security management.
* Both Internet interfaces can be selected for DIA in workflows (Answer C): In Versa workflows, it is possible to configure both Internet interfaces for DIA. This configuration enhances redundancy and ensures that there is always an active path for Internet access, which is critical for maintaining high availability and network resilience.
The option A (All underlay interfaces belong to the same VR instance) is not typically true in complex deployments where separation of control and data planes is required for better management and security.
Option D (Only one Internet interface can be selected for DIA in workflows) is incorrect because Versa SD-WAN allows multiple interfaces to be configured for DIA to leverage failover and load-balancing capabilities.
References:This explanation is based on the standard practices of deploying Versa SD-WAN solutions, where the architecture supports multiple virtual routers and the capability to configure multiple interfaces for DIA.

(Choose two.)
- A. Versa Analytics sites availability dashboard
- B. Versa Director troubleshooting tools
- C. Versa Director device monitoring dashboard
- D. Versa Analytics SD-WAN dashboard
Answer: A,C
Explanation:
In the event of a network outage, to verify the live status of the WAN links, Versa Director device monitoring dashboard and Versa Analytics sites availability dashboard are the tools to use.These components provide real-time visibility into the status and health of WAN links, allowing for rapid identification and troubleshooting of connectivity issues.
NEW QUESTION # 18
By default, when configuring DIA through workflows, which protocol runs between the tvi interfaces connecting an Internet VR with the LAN VRF?
- A. OSPF
- B. VRRP
- C. BGP
- D. static routing
Answer: C
Explanation:
By default, when configuring Direct Internet Access (DIA) through workflows, the protocol that runs between the tenant virtual router (VRF) and the transport WAN Virtual Router (VR), connected by the TVI interfaces, is EBGP (External Border Gateway Protocol). This protocol is used to control route distribution and is a fundamental part of the VOS Edge Device DIA Architecture. In such a configuration, the tenant VRF uses EBGP to advertise the default route, which is resolved using the logical tunnel created for DIA.
NEW QUESTION # 19
What are two roles of a Versa Controller? (Choose two.)
- A. to provide clock synchronization to the SD-WAN branches
- B. to provide connectivity to the rest of the head-end components
- C. to onboard the SD-WAN branches
- D. to provide Internet breakout to the SD-WAN branches
Answer: B,C
Explanation:
The roles of a Versa Controller include onboarding SD-WAN VOS branches into the network and maintaining a secure control channel with each node. The Versa Controller authenticates branch VOS instances, handles management activities between the remote and headend nodes, and distributes control plane information. It does not provide Internet breakout, which is a function typically performed by edge devices at the branches themselves, nor does it provide clock synchronization to the branches, which is generally a function of network protocols like NTP that operate independently of SD-WAN control.
NEW QUESTION # 20
You are asked to configure an SD-WAN branch so that Internet bound traffic uses the local Internet link.
In this scenario, which template provides this configuration?
- A. Service Chain Template
- B. QoS Template
- C. Post-staging Template
- D. Application Template
Answer: A
Explanation:
To configure an SD-WAN branch so that Internet-bound traffic uses the local Internet link, the Service Chain Template is used. This template is part of the Director Workflows and allows the local breakout of internet traffic directly from the branch, bypassing the central or regional breakout points. This is an essential component of the Versa Secure SD-WAN design, where traffic intended for the internet can be directed through the most efficient route, often through a local Internet link at the branch site, instead of being backhauled to a central location.
NEW QUESTION # 21
Review the exhibit.
Which hub topology is shown in the exhibit?
- A. spoke-to-spoke direct
- B. spoke-hub-hub-spoke
- C. spoke-to-spoke via hub
- D. spoke-to-spoke only
Answer: C
Explanation:
The diagram in the exhibit illustrates a hub and spoke topology where the spokes connect through a central hub. This is evident from the dashed lines that show the data flow between the spokes is mediated by the hub (Hub1). In this topology, while the spokes may have direct connections, the data flows between them pass through the hub. This kind of topology is commonly used in SD-WAN deployments to simplify routing and policy enforcement, which are managed centrally at the hub, as opposed to setting up direct paths between all spoke sites, which would be indicative of a full mesh or spoke-to-spoke direct topology.

NEW QUESTION # 22
Review the exhibit.
Which set of conditions match the policy shown in the exhibit?
- A. Traffic flows that meet any of the following two conditions:
Source Zone - Intf-LAN1 Zone
Source Zone - Intf-WLAN-Zone
In addition, the below condition must also match
Application - SharePoint - B. Traffic flows that meet any one of the following three conditions:
Source Zone - Intf-LAN1 Zone
Source Zone - Intf-WLAN-Zone
Application - SharePoint - C. Traffic flows that meet any one of the following three conditions:
Source Zone - Intf-LAN1 Zone
Source Zone - Intf-WLAN-Zone
Application - SharePoint - D. Traffic flows that meet all of the following two conditions:
Source Zone - Intf-LAN1 Zone
Source Zone - Intf-WLAN-Zone
In addition, the below condition must also match
Application - SharePoint
Answer: A
Explanation:
The policy shown in the exhibit appears to match traffic flows based on multiple conditions involving the source zone and the application. Given the information in the screenshot:
* The policy is configured with multiple zones as source zones:Intf-LAN1-ZoneandIntf-WLAN-Zone.
* An application is specified:SHAREPOINT.
The policy is likely to be applied to traffic originating from either of the specified zones and specifically related to the SharePoint application. This implies that both conditions related to the source zones are not mutually exclusive but rather a union; the same goes for the application condition.
Given this interpretation, the correct set of conditions that match the policy shown would be:
B:Traffic flows that meet any of the following two conditions:
* Source Zone - Intf-LAN1 Zone
* Source Zone - Intf-WLAN-Zone
In addition, the below condition must also match:
* Application - SharePoint
This means that traffic will match the policy if it comes from either theIntf-LAN1-Zoneor the Intf-WLAN-Zoneandis SharePoint application traffic.
However, to be more precise in the context of Versa SD-WAN configurations, it's important to note that policies are usually applied when all conditions within a single rule are met. If the configuration in the screenshot intends to express that traffic is matched if it comes from either of the two zones and is for the SharePoint application, then the correct answer should reflect this logic. If the configuration system is set up to require all conditions in a rule to be met, then the answer could potentially be different. Since the user interface design can sometimes vary, it's important to understand the specific logic of the system in question.

- A. Versa Director
- B. Versa Hub
- C. Versa Analytics
- D. Versa Gateway
Answer: A,C
Explanation:
The Versa Secure SD-WAN Head-end consists of the Versa Controller, Versa Director, and Versa Analytics.
However, when referring to headend nodes as components, the Versa Director and Versa Analytics are part of it. The Versa Controller, while an integral part of the SD-WAN control plane, is not listed under 'Headend Node' in the provided documentation. The Versa Director and Versa Analytics work in conjunction to manage a network of VOS devices, with the Director being the provisioning and management application and Analytics providing the analytics engine. Versa Gateway is not mentioned as part of the head-end components in the context provided.
NEW QUESTION # 26
You have configured a Versa Secure SD-WAN solution with a Full Mesh topology.
In this scenario, which statement is true?
- A. The CPE devices send SLA probes on the active forwarding path only.
- B. The CPE devices send SLA probes to the Versa Controller, and the Versa Controller distributes active site statistics to other CPEs.
- C. The CPE devices send SLA probes to the Versa Controller, and the Versa Controller relays the probes to CPE devices.
- D. The CPE devices send SLA probes on all possible transport paths between devices.
Answer: D
Explanation:
In a Versa Secure SD-WAN solution configured with a Full Mesh topology, the true statement is that CPE devices send SLA probes on all possible transport paths between devices (B). This approach ensures any-to-any communication among branches, enabling direct communication using overlay tunnels without the need to transit through a hub or centralized site. SLA monitoring probes are utilized to track reachability and to measure link metrics for each access circuit towards any given remote site. These probes are critical for maintaining high-quality communication paths and for implementing traffic steering based on predefined SLA parameters.

These templates are crucial for automating device provisioning and configuration within the Versa SD-WAN architecture.
NEW QUESTION # 29
Which two parts in the SD-WAN policy rules are used to steer traffic? (Choose two.)
- A. Logging
- B. Anti-virus
- C. Schedules
- D. Applications
Answer: C,D
Explanation:
In SD-WAN policy rules, two parts used to steer traffic are Schedules and Applications. Schedules allow administrators to define when certain policy rules should be active, effectively determining the timing for when traffic steering decisions should be applied. Applications, on the other hand, enable traffic steering decisions based on the type of application traffic being detected. This allows for more granular control and optimization of traffic flows based on application requirements and characteristics.

NEW QUESTION # 35
Which two statements about a Versa Secure SD-WAN deployment are true? (Choose two.)
- A. By default, all data traffic is forwarded on unencrypted tunnels.
- B. By default, all control traffic is forwarded on unencrypted tunnels.
- C. By default, all data traffic is forwarded on IPSec tunnels.
- D. By default, all control traffic is forwarded on IPSec tunnels.
Answer: C,D
Explanation:
In a Versa Secure SD-WAN deployment, the following statements about traffic forwarding are accurate:
* By default, all data traffic is forwarded on IPSec tunnels (Answer A): Versa SD-WAN solutions typically encrypt all data traffic by default using IPSec tunnels. This security measure ensures that data remains protected while transiting over the public or private WAN, safeguarding against eavesdropping and data theft.
* By default, all control traffic is forwarded on IPSec tunnels (Answer B): Similarly, control traffic in Versa SD-WAN is also encrypted and sent through IPSec tunnels. This practice secures the signaling and management traffic, preventing potential attacks that could target the network's control plane.
Options C (By default, all data traffic is forwarded on unencrypted tunnels) and D (By default, all control traffic is forwarded on unencrypted tunnels) are incorrect as they contradict the security-oriented design of Versa SD-WAN, which emphasizes the encryption of both data and control traffic by default.
References:This explanation utilizes Versa SD-WAN's documented security features and general network security protocols that prioritize encrypted communications for both data and control planes.
NEW QUESTION # 36
What are two features of the Versa Secure SD-WAN? (Choose two.)
- A. on demand resource pooling
- B. single-pane-of-glass management with embedded analytics
- C. multitenancy and Role Based Access Control (RBAC)

Answer: B,C
NEW QUESTION # 37
Review the exhibit.
Your manager asks you to explain what the DIA option does when configuring split tunnels as shown in the exhibit.
In this scenario, which statement is true?
- A. It implements a BGP default route advertisement into the control network of the tenant.
- B. It implements a BGP default route advertisement into the underlay transport of the tenant.
- C. It implements a BGP default route advertisement into the overlay network of remote tenants.
- D. It implements a BGP default route advertisement into the local LAN VRF of the tenant.
Answer: D
Explanation:
The Direct Internet Access (DIA) option in the configuration of split tunnels for an SD-WAN device, as shown in the exhibit, is a feature that allows traffic destined for the internet to bypass the SD-WAN overlay network and be sent directly out of the local branch's internet connection. This can significantly improve access to cloud services andinternet performance by reducing latency and avoiding backhauling traffic through the corporate data center or another central location.
When DIA is enabled, traffic that is destined for the internet does not traverse the SD-WAN overlay network; instead, it is routed directly from the branch to the internet. The SD-WAN appliance can still enforce security policies on this traffic, and it can also be programmed to dynamically decide whether to use the DIA path based on real-time performance metrics and other criteria.
By implementing the BGP default route advertisement into the local LAN Virtual Routing and Forwarding (VRF) of the tenant, the SD-WAN appliance advertises a default route to the local site. This allows the site to route internet-bound traffic directly to the internet without having to send it across the SD-WAN network. This eases the internal network traffic load and can potentially reduce costs associated with data transmission over the corporate WAN.
References:The explanation provided above aligns with standard SD-WAN architecture and practices for configuring split tunnels and the use of Direct Internet Access in SD-WAN environments.
