Versa Networks Updated VNX100 Exam Questions and Answers by brayden

To require users to justify their access to specific types of websites, such as social media sites, theCaptive Portal (Answer D)feature is used. This feature intercepts users' web requests, redirecting them to a portal where they must authenticate or provide justification for accessing the requested site. It is particularly useful in enforcing corporate policies and ensuring that access to certain types of sites is for legitimate business purposes.

References:The use of captive portals for controlling and monitoring access to web resources is a common practice in network administration, as outlined in Versa's configuration guidelines for secure network access and user authentication protocols.

The Versa Operating System (VOSTM) includes a broad set of IP services. Specifically, it includes Carrier-Grade NAT (CG-NAT), which allows private network spaces to be mapped to public IP addresses; Multicast protocols such as IGMP and PIM (in Releases 20.2 and later); and the NTP server for time synchronization. HTTP Proxy and CDN are not listed among the included features for the Versa Operating System in the provided documents.​

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.​
