VNX100 Exam Dumps - Versa Certified SD-WAN Associate

To apply a new URL filtering profile across all of the SD-WAN CPEs in response to a security event, you would use the Next Generation Firewall (NGFW) Template. This template is specifically designed to handle security functions, including application control, intrusionprevention, and URL filtering. By using the NGFW Template, you can enforce URL filtering policies that block or allow traffic based on URLs and categories, which is integral to controlling access to websites and ensuring network security​​.

The default load balancing algorithm set in an SD-WAN Forwarding Profile is Weighted Round Robin (WRR). This algorithm assigns weights to each path based on the available bandwidth on the access circuit. WRR is recommended when paths with equal priorities are provisioned with different bandwidths, ensuring that traffic is distributed proportionally to the bandwidth of each path, which optimizes the utilization of network resources and maintains load balancing across the WAN circuits​​.

Versa Secure Access (VSA) is designed to integrate with various authentication servers, including LDAP, and supports multifactor authentication methods like email and time-based OTP, integrating with authentication applications such as Duo, Google Authenticator, and Microsoft Authenticator. This makes the platform versatile in terms of supporting different enterpriserequirements for user authentication and enhancing security.​

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.

In the architecture of Versa SD-WAN, the control plane plays a crucial role in the discovery and management of network topology:

• SD-WAN topology is discovered using MP-iBGP (Answer B): Versa utilizes Multi-Protocol Interior Border Gateway Protocol (MP-iBGP) for the discovery and management of the SD-WAN topology. This protocol helps in the efficient exchange of routing information within the network, enabling the Versa Director and other network components to maintain an updated view of network topology.
• Versa Private Address Family is used to advertise topology information (Answer C): This unique address family within Versa’s ecosystem is specifically designed to handle and distribute topology information across the network. It ensures that all relevant Versa devices are aware of the network structure and any changes to it.
