Versa Networks Versa Certified SD-WAN Specialist (VNX300) 認定 VNX301 試験問題 (Q29-Q34):

質問 # 29
Examine the exhibit below.
You are configuring an IPsec tunnel towards a non-SD-WAN site over the INETTransport-VR. The site IP address is 10.1.1.1. This tunnel is for traffic between the 192.168.100.0/24 and the 192.168.200.0/24 LAN networks. The tunnel does not establish.
Referring to the exhibit, which statement is correct?

正解：C

解説：
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.


質問 # 30
A customer wants all voice sessions pinned to the DNS-resolved SaaS path selected at session creation, so the sessions are not moved mid-flow when the SaaS monitoring score changes. Which forwarding-profile behavior is most relevant?

正解：C

解説：
The correct answer is A . In Versa SD-WAN application steering, SaaS or cloud-path selection can use monitoring and DNS-based behavior to determine the best path for an application. For real-time applications such as voice, session stability is often more important than aggressively moving active flows after every path- score change. Session pinning to DNS path is the forwarding-profile behavior that keeps a session associated with the path selected when the DNS/application path decision was made.
This matters because voice and collaboration applications can be sensitive to path changes, packet reordering, and jitter. Pinning prevents active sessions from being unnecessarily moved mid-flow as SaaS monitoring scores change, while still allowing new sessions to take advantage of newer path decisions.
Packet striping is used to distribute packets across multiple circuits and can create reordering concerns for some applications. Symmetric forwarding controls reverse-path behavior rather than DNS-based session stability. Random packet drop is a DoS mitigation action, not a SaaS path-selection feature.
Therefore, the best answer is Session pinning to DNS path.


質問 # 31
Examine the exhibit below.
You are onboarding the SOLDEU-R2 branch device using the staging script. You cannot get a Versa- Provider-Controller-VR IP address assigned, indicating that the IPsec tunnel to the corrector has not come up.
You verified that the cables have been connected to the correct ports.
What has caused this issue?

正解：A

解説：
The issue is caused by specifying the incorrect WAN port in the staging script. In the exhibit, the SOLDEU- R2 branch is physically connected to the Internet cloud through vni-0/0 , while vni-0/1 is shown as the inter- device link toward SOLDEU-R1. However, the show interfaces brief output shows that the WAN IP address
192.168.122.121/24 has been assigned to vni-0/1.0 , not to the Internet-facing interface. Since the cables are confirmed to be connected correctly, the mismatch must be in the staging script interface selection, not in the cabling.
Versa documentation states that during SD-WAN staging, the branch establishes an IKE session with the Controller, and after that the Controller assigns an IP address to the branch device. Versa troubleshooting guidance also states that after transport connectivity to the Controller is established, the branch forms IKE-based IPsec connectivity, and if this succeeds, the ptvi interface toward the Controller comes up. If IKE/IPsec fails, the ptvi interface remains down. Because the staged WAN IP is placed on the wrong VNI interface, the branch cannot reach the Controller over the intended Internet transport, so the Controller tunnel does not come up.


質問 # 32
A Versa Director operator wants to monitor CPU, memory, disk, recent events, uptime, HA status, package information, and license details from the Director GUI. Which top-level tab should be used?

正解：A

解説：
The correct answer is A . Versa documentation states that from a Director node, administrators can monitor the Director node itself, provider organizations, tenants, and VOS devices. The procedure begins by selecting the Monitor tab in the top menu bar. When a Director node is selected, the monitor screen displays panes such as System Detail , Recent Events , Package Information , Uptime , High Availability , and License .
This view is intended for operational monitoring and troubleshooting. It allows administrators to see system resource status, recent alarms and events, software package details, uptime, HA configuration, and licenses installed on managed VOS devices.
Workflows are used for provisioning and template-based configuration, not monitoring these system panes. Analytics Search is useful for querying logs and flow records, but it is not the Director system- monitoring screen described in the question. Administration > Connectors relates to integration and resource connectivity rather than Director node health and license monitoring. Therefore, the correct location is the Monitor tab.


質問 # 33
You want to ensure that devices in your branch sites cannot source traffic from IP addresses that are not assigned to the branch sites. What will solve this problem?

正解：B

解説：
The correct answer is B . The requirement is to stop branch devices from sourcing traffic using IP addresses that do not belong to the branch. This is a source-address enforcement problem, so the correct control is a stateful firewall policy that permits only traffic whose source IP address matches the valid branch LAN prefix or branch-assigned address range. Versa's stateful firewall configuration documentation explains that firewall policy rules include source matching, where the administrator selects the source zone and one or more source addresses to which the rule applies.
By creating an allow rule for the legitimate branch source prefixes and placing a deny rule for all other sources from the branch LAN zone, the VOS device prevents spoofed or unauthorized source addresses from leaving the branch. This is consistent with Versa security policy behavior, where firewall rules evaluate traffic based on zones, addresses, services, applications, and other match criteria. Captive portal verifies user identity but does not directly prevent IP spoofing. An IP filter profile based on applications does not ensure the source address belongs to the branch. Option D is incorrect because allowing traffic to the assigned LAN range controls destination traffic, while this requirement is about validating the source IP address of outbound branch traffic.
