Versa Networks VNX301 Exam With Confidence Using Practice Dumps

The correct answer is A . The exhibit shows that the IPsec VPN is being configured with Tunnel Routing Instance: XIAN-Control-VR . However, the question states that the tunnel is toward a non-SD-WAN site over the INET-Transport-VR . For a site-to-site IPsec tunnel, the tunnel routing instance must match the routing instance used to reach the peer public IP address. In this case, the remote non-SD-WAN peer is 10.1.1.1 , and the intended underlay transport is INET-Transport-VR , not the Control VR.

Versa troubleshooting documentation explains that routing instances are used to define where traffic is sourced and forwarded. For example, configuration examples select routing instances when enabling services or initiating tests, and traffic must use the correct WAN or transport routing instance to reach the remote endpoint. Versa branch troubleshooting also emphasizes that after transport connectivity is available, the branch establishes IKE-based IPsec connectivity; if that connectivity fails, the IPsec-related interface remains down.

Changing the routing instance to global would not be correct because the intended path is specifically INET-Transport-VR. A higher precedence value is not required to establish the tunnel. The policy selector shown already defines local-to-remote interesting traffic, and the key failure is the incorrect tunnel routing instance.

The correct answers are A and C . Versa supports upgrading deployed VOS branch devices either directly on the VOS appliance or centrally through Versa Director. The Director-based method is performed from the Administration > Appliances area: Versa documentation says to select one or more Controller nodes or VOS devices, click the Upgrade Selected Appliances icon, choose the software image package, and proceed with the appliance upgrade. The same upgrade procedure is referenced for remaining VOS branch devices, including the option to upgrade branches individually or all at once.

A CLI-based upgrade using a software .bin package is also a valid operational method when the image is copied to the device and installed locally, particularly for controlled or recovery-style maintenance. Option B is not the best answer for already deployed branch upgrades because the Preferred Software Version field applies to zero-touch provisioning; Versa states that during ZTP, Director upgrades a branch to the preferred version if applicable. That setting influences onboarding behavior, not the normal upgrade workflow for already deployed branches. Option D is incorrect because System > Director Upgrade is used to upgrade the Versa Director node itself, not VOS branch appliances.

The correct answer is B . The exhibit shows the OSPF neighbor in the exst state, which means Exchange Start . Versa documentation lists the OSPF neighbor state codes and identifies exst as “exchange start,” followed by exchange, loading, and full. In normal OSPF adjacency formation, neighbors progress through initialization and two-way communication before they negotiate database exchange. If the neighbor becomes stuck in ExStart or Exchange, a common and highly probable cause is an MTU mismatch between the two OSPF peers. During database description packet negotiation, the peers must agree on parameters that allow LSDB exchange; an MTU mismatch can prevent the adjacency from advancing to Full.

Option A is less likely because an area mismatch usually prevents the neighbor relationship from forming correctly rather than leaving it stuck in ExStart. Option C is also incorrect because the neighbor has already progressed beyond early states, which indicates that bidirectional communication has occurred. Option D is not the best answer because dropping OSPF multicast 224.0.0.5 would typically prevent discovery or keep the adjacency in an earlier state, not specifically in ExStart. Therefore, the probable cause is an interface MTU mismatch.
