Versa Networks Versa Certified SD-WAN Specialist (VNX300) 認定 VNX301 試験問題 (Q10-Q15):

質問 # 10
Examine the exhibit below.
The exhibit shows a device group created for a new group of hubs. The device template called "BMBF- TEMPLATE" has an Address object called "Server". A network administrator creates the Class of Service Template called "Ship-CoS-IT" that has an Address object with the same name. Then it tries to onboard a new device to this device group.
Which statement is true about the configuration that this device will have?

正解:B

解説:
The correct answer is D . In the displayed post-staging template association order, the device template BMBF- TEMPLATE is applied before the QoS service template Ship-CoS-IT . Versa documentation explains that device templates, also called post-staging templates, provide the baseline configuration for devices, while service templates are service-specific configurations that can be applied to device configurations. It also states that service templates are associated with device groups and that, in a device group, the administrator can choose the order in which service templates are applied.
Because the QoS template is later in the shown association order, the final merged device configuration uses the Address object definition from the QoS template when the same object name exists in both templates. It does not automatically create two copies of the same Address object, because the object name is the key for the configuration element. It also should not fail merely because the same object name exists in a later template; the merge behavior resolves the effective configuration according to the template order. Therefore, the onboarded hub device receives the Server Address object version from Ship-CoS-IT, the QoS template.


質問 # 11
A customer is running VOS Release 22.1.3 on both the speed-test client and server. Which sequence is used by the Versa speed test to calculate bandwidth?

正解:C

解説:
The correct answer is C . Versa documentation states that for Releases 22.1.3 and later , the speed test factors in network latency to derive results. In these releases, the speed test is performed in three stages : a ping test, an upload test, and a download test. The ping test calculates link latency, and the speed test uses that latency data while performing the upload and download portions.
The same documentation notes that the speed test can measure bandwidth speeds up to 1 Gbps, with actual measurement depending on factors such as in-path shapers and latency. It also states that the test may use up to 45 MB of data per upload or download in the best case and 90 MB for a complete test.
Older releases behave differently. For Releases 21.2 and earlier, the speed test is performed in two stages: upload and download. Therefore, because the question specifically states Release 22.1.3 on both client and server, the correct sequence is ping, upload, and download.


質問 # 12
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:D

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.


質問 # 13
You are configuring the BGP routing protocol between a Versa Secure SD-WAN CPE with AS number
64514 and two upstream service providers: SP1 with AS number 64515 and SP2 with AS number 64519. You want to prefer BGP routes learned from AS 64515 over routes learned from AS 64519. Which BGP path attribute would be used to accomplish this task?

正解:D

解説:
The correct answer is LOCAL_PREF . In BGP, the Local Preference attribute is used inside an autonomous system to influence which exit path is preferred for outbound traffic. In this scenario, the Versa Secure SD- WAN CPE receives routes from two upstream service providers, SP1 and SP2. To prefer routes learned from AS 64515 over routes learned from AS 64519, you would apply a BGP import or route policy that assigns a higher local preference to routes received from SP1. Versa SD-WAN design guidance shows this exact routing concept: an import policy can manipulate the Local-Pref attribute to prefer one advertised route path over another. The Versa output examples also display "Local Preference" as a BGP route attribute used in route selection.
MULTI_EXIT_DISC, or MED, is generally used to influence how a neighboring AS enters your AS, not how your CPE prefers routes learned from different upstreams. ORIGIN is part of BGP best-path selection but is not normally the administrative tool used to prefer one provider. NEXT_HOP identifies the next-hop address and does not directly define route preference.


質問 # 14
A new SD-WAN branch has completed factory-default onboarding and Versa Director has pushed the staging configuration. After reboot, the branch still tries to connect to the staging server instead of the Controller.
Which configuration item is most likely incorrect or missing in the stage-two configuration?

正解:D

解説:
The correct answer is A . During Versa SD-WAN onboarding, the branch uses the staging server only in the early part of the process. Versa documentation states that in Stage 1 , the branch starts an IKE session with the staging server, receives an IP address, and is informed of the Versa Director IP address. In Stage 2 , Versa Director pushes the stage-two configuration to the branch through the staging server. In this stage-two configuration, the Controller IP address is given as the remote IP address in the IPsec profile , and the branch is rebooted. After reboot, the branch should establish the IKE session with the Controller.
If the branch keeps trying to connect to the staging server after the stage-two reboot, the most likely issue is that the stage-two IPsec profile still points to the staging server or does not contain the correct Controller remote IP. Analytics, DHCP, and URL filtering settings do not determine whether the branch moves from staging-server connectivity to Controller IKE connectivity.
