VNX100 Exam Dumps : Versa Certified SD-WAN Associate

When a speed test fails, it could be due to the speed test module not being activated or the speed test server not being enabled at the remote site. If the speed test module has not been activated, the required functionality to conduct the test will not be operational. Similarly, if the remote site does not have the speed test server enabled, it won't respond to speed test requests. Issues with the SLA path status or client configuration might be relevant to the performance and reachability but are not cited as direct reasons for a speed test failure within the documentation provided.

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 theIntf-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.

Versa CPEs support a variety of Quality of Service (QoS) functions to ensure effective bandwidth management and priority handling of network traffic. The three functions supported are:

• Hierarchical queuing (Answer B): This QoS function allows for the creation of a multi-level queue structure, enabling more granular control of traffic prioritization and bandwidth allocation among various traffic classes.
• Egress policing (Answer C): This involves setting maximum bandwidth limits for outbound traffic on network interfaces to prevent any traffic class from consuming excessive bandwidth and impacting the performance of other critical applications.
• Classification (Answer D): This is the process of marking packets based on predefined criteria, which can include source or destination IP addresses, ports, or application types. Classification is essential for applying the appropriate QoS policies to different types of traffic.

References:These functionalities are extensively described in Versa’s configuration manuals, where the setup and implications of each QoS feature are discussed, ensuring optimal network performance and adherence to organizational policies.
