VNX301 Dumps with Practice Exam Questions Answers

The correct answer is A . In Versa SD-WAN traffic steering, forwarding profiles define how traffic is mapped to WAN circuits, how next hops are selected, and how traffic behaves when SLA conditions are violated. If the requirement is to stop traffic when no SLA-compliant path is available, the relevant behavior is the SLA Violation Action . Setting this option to Drop prevents the VOS device from forwarding the matching traffic over a circuit that does not satisfy the policy’s SLA requirements.

This is the opposite of using Forward , which allows traffic to continue even when the available next hops violate the SLA. Forward may be appropriate for best-effort applications where degraded delivery is better than no delivery, but it is not appropriate for strict business-critical applications that must not use a degraded path.

Nexthop Failure Action controls how the system behaves when a next hop fails, such as waiting for recovery or re-evaluating. Header compression affects packet overhead, and the recompute timer controls periodic recalculation timing. None of those settings directly enforce “drop when SLA is not met.”

The correct answer is B . Versa documentation for internet speed tests explains that when you run an internet speed test from a Director node, it creates approximately 200 sessions . This is useful for measuring aggregate throughput, but it does not represent the behavior of a single application flow. The same documentation states that you can run a speed test with a single session from the device CLI, and that this is useful for simulating file transfer rates when using SCP or FTP .

Therefore, when the goal is to understand how a single file transfer behaves, the CLI-based single-session test is the best option. A default Director-based test may produce higher aggregate results because multiple sessions can use parallelism and better fill the pipe.

show interfaces brief is useful for interface status and addressing, but it does not measure file-transfer throughput. SLA latency is useful for path-quality monitoring, but latency alone does not show single-session TCP throughput.

The correct answer is B . Versa documentation describes checking for asymmetrical SD-WAN paths when troubleshooting bandwidth and throughput issues. It gives the example of traffic being transmitted on one transport network and returning on another transport network that has different bandwidth. To check whether traffic is traversing an asymmetrical SD-WAN path, Versa recommends using show orgs org organization-name sessions sdwan brief.

In that output, the key fields are RX WAN CKT and TX WAN CKT . If the SD-WAN paths are symmetrical, the circuits shown in the RX and TX WAN circuit fields must be the same on the local and remote sites. If traffic goes out over Internet and returns over MPLS, throughput may differ depending on the bandwidth and quality of each circuit.

Source and destination zones are security-policy concepts, while BGP local preference and MED are routing attributes. Tenant ID and VSN ID identify context, but they do not directly prove directional WAN-circuit asymmetry.

The correct answer is A . Versa CGNAT troubleshooting documentation includes per-pool and resource counters that show allocation behavior and failures. The counters include values such as bindings allocated, bindings freed, allocation failures, out-of-address errors, and out-of-ports errors. It also shows that CGNAT source-port resources are divided and distributed to worker threads by Versa RFD/RFM, and that allocated source-port ranges can be viewed using show rfm table src-port allocated.

If out-of-ports errors increase while out-of-address errors remain zero, the pool still has usable translated IP addresses, but the available port resource for NAT bindings is exhausted. This commonly occurs when too many concurrent sessions share a limited public IP or source-port range. The corrective action would be to expand the NAT resource, add more public translated IPs, adjust port allocation, or reduce excessive session usage.

A missing NAT IP pool would more likely produce out-of-address problems. A wrong zone match might prevent translation entirely, and OSPF in the LAN VR is unrelated to CGNAT port-resource exhaustion.
