NEW QUESTION # 52
Examine the exhibit below.
A DoS Profile shown in the exhibit is applied to an SD-WAN branch.
Referring to the exhibit, which statement is correct?
Answer: C
Explanation:
The correct answer is B . The DoS profile in the exhibit is a Classified Profile using Source IP Only as the classification key. For TCP flood protection, the profile is enabled and shows an Alarm Rate of 5000 packets per second , an Activate Rate of 7000 packets per second , a Maximum Rate of 100000 packets per second , a Drop Period of 300 seconds , and an action of Random . This means the first threshold, 5000 pps, is used to trigger alarm behavior, while the second threshold, 7000 pps, activates the configured mitigation action. Since the selected action is Random , packets are randomly dropped when the TCP rate reaches the activate threshold.
Versa documentation shows that DoS policies can match traffic using source, destination, service, application, schedule, IP version, DSCP, and other conditions, and that a DoS policy can set either an aggregate or classified DoS profile. It also documents that DoS policies support enforcement actions and logging through LEF profiles for DoS events. Therefore, 7000 pps does not merely generate an alarm, and it does not mean complete dropping. Complete dropping is not selected in the exhibit.
NEW QUESTION # 53
Examine the exhibit below.
You are deploying Versa Secure SD-WAN and require high availability for the Versa Directors. You configured the Versa Director high availability parameters shown in the exhibit. With the parameters shown, which two statements are true? (Choose two.)
Answer: A,C
Explanation:
Comprehensive and Detailed 150 to 250 words of Explanation From Versa Networks SDWAN Topics:
The correct answers are B and D . In the exhibit, Enable Auto Switchover is not selected. However, the Failover Timeout value is configured as 300 seconds . Versa Director HA documentation states that the Failover Timeout is the timeout period before the standby Director node can promote itself to become the active Director node. Therefore, if the active or primary Director fails, the backup Director can automatically assume the active role after the failover condition and timeout are met.
The important distinction is that Auto Switchover controls revertive behavior after recovery, not the initial standby takeover during failure. Versa documentation explains that Director HA is non-revertive by default.
This means that when the designated master or primary Director comes back online after recovery, it is not automatically promoted back to active unless automatic switchover is enabled. To make the designated active Director automatically reclaim the active state after recovery, Enable Auto Switchover must be selected and the Auto Switchover Timeout must expire.
NEW QUESTION # 54
During onboarding, Versa Director shows the first branch-connect notification for a new CPE, but no later staged branch-connect notification appears. Which troubleshooting area should be investigated first?
Answer: A
Explanation:
The correct answer is B . Versa branch lifecycle notifications are generated at different stages of onboarding.
The first notification indicates that the branch connected using factory-default configuration. After that notification, Versa Director pushes the staging configuration to the branch and requests a reboot. After rebooting with staging configuration, the branch should connect again to the Controller, and a later branch- connect notification should appear.
If this later staged connection notification does not appear, Versa's troubleshooting guidance says to debug either the data path or IPsec connectivity from the branch to the Controller. This makes sense because the branch must have working transport reachability and IKE/IPsec establishment toward the Controller before it can continue the SD-WAN lifecycle.
Analytics disk usage, LDAP authentication, and URL filtering are not part of the branch staging control path. They may affect monitoring, user identity, or security inspection after the site is operational, but they do not explain why the branch stops after the initial factory-default onboarding notification.
NEW QUESTION # 55
You configured a Versa speed-test server on a VOS device, but the client cannot start the bandwidth test. A firewall exists between the client and server. Which port must be allowed through the firewall?
Answer: C
Explanation:
The correct answer is A . Versa link-bandwidth troubleshooting documentation explains that a VOS device can be configured as a Versa speed-test client, a Versa speed-test server, or both simultaneously. After the server is configured, the client starts the test by initiating a TCP-based connection toward the speed-test server. The server listens on port 5201 . The documentation includes an explicit note that if the VOS device is behind a firewall, port 5201 must be open .
This is different from the SD-WAN overlay data path, which commonly uses UDP-based transport encapsulation, and different from internet speed-test traffic, which uses other ports depending on the specific test type. In this scenario, the question states that a Versa speed-test server was configured, so the relevant requirement is TCP 5201 reachability from the client to the server.
TCP 443 may be used for management or web access, UDP 4790 is associated with SD-WAN transport encapsulation, and UDP 53 is DNS. None of those replace TCP 5201 for Versa speed-test server operation.
NEW QUESTION # 56
A branch device is powered on with factory-default staging configuration. The device establishes an IKE session to the staging server and receives an IP address, but it does not proceed to establish an IKE session with the Versa Controller. Which staging phase is failing?
Answer: C
Explanation:
The correct answer is B . In Versa SD-WAN onboarding, the branch progresses through three staging phases.
In Stage 1 , the branch uses its factory-default configuration to start an IKE session with the staging server.
After the IKE session comes up, the staging server assigns an IP address to the branch and notifies the branch of the Versa Director IP address. Versa Director is also notified that the branch has come up.
In Stage 2 , Versa Director pushes the stage-two configuration to the branch through the staging server. This stage changes the IPsec profile so that the Controller IP address becomes the remote IP. The branch reboots and then attempts to establish the IKE session with the Controller. If the device successfully completed Stage
1 but never forms the Controller IKE session, the failure point is Stage 2.
Stage 3 is later, when the device receives stage-three configuration, becomes operational, and creates Controller IPsec plus branch-to-branch VXLAN/ESP sessions. Therefore, the described issue is a Stage
2 staging failure.
