NEW QUESTION # 42
Which three notification methods does Versa Director allow you to configure for sending system event notifications? (Choose three.)
Answer: A,B,D
Explanation:
The correct answers are A, B, and E . Versa Director supports multiple notification and event-publishing mechanisms. For email-style system and alarm notifications, Versa Director supports SMTP configuration.
The Director documentation lists Configure SMTP Notifications and explains that email templates require SMTP notifications to send test emails or operational messages.
Versa Director also supports webhook notifications. The Director GUI overview states that Notification Configuration includes webhook-based notifications for alarms, and the Director documentation includes a dedicated workflow for configuring webhook notifications for alarms.
Kafka is also a supported event-notification method. Versa's Kafka Notifications documentation states that Versa Director can publish event notifications to an Apache Kafka server when events occur on a Director node or a VOS device. It also lists notification topics for device events, Director events, Director task notifications, and object-change event notifications.
MMS is not a Versa Director system event notification method. SMS can be configured for text messaging in some notification contexts, but for the three methods listed for system event notifications in this answer set, the verified options are SMTP, Webhook, and Kafka.
NEW QUESTION # 43
During branch onboarding, you need to verify whether the Controller has sent branch-connect and branch- disconnect notifications to Versa Director. Which CLI command should be used?
Answer: A
Explanation:
The correct answer is A . Versa troubleshooting documentation states that after a branch device successfully establishes an IPsec connection to the Controller node, the Controller sends a notification to the Director node. To display the details of this notification, the documentation instructs administrators to issue the show alarms CLI command. It also provides examples using show alarms | match branchd | match br101 to view branch-connect and branch-disconnect events.
These alarm entries are valuable during onboarding because they show whether the branch reached the Controller, whether staging progressed, and whether the branch later disconnected. For example, branch lifecycle notifications include factory-default connection, staged connection, Stage 3 connection with WAN IP addresses, and branch disconnect events.
show system storage is useful for disk usage, show interfaces detail helps with link state, speed, duplex, and interface counters, and show cgnat acl info is used for CGNAT matching. None of those commands directly confirms branch lifecycle notifications between Controller and Director.
NEW QUESTION # 44
What are two features of the Stateful Firewall service in the Versa Operating System? (Choose two.)
Answer: A,B
Explanation:
The correct answers are A and D . Versa stateful firewall service includes classic firewall functions that track sessions and enforce traffic policy, and it can work with DoS policy enforcement. Versa's CLI guide includes Configuring DoS policies under the security configuration area, where DoS rules can match on source, destination, services, applications, URL category, IP version, DSCP, TTL, EtherType, and other packet or session attributes, and can then apply aggregate or classified DoS profiles. This validates DoS protection as a stateful firewall/security service capability.
Application-Level Gateways, or ALGs , are also associated with stateful firewall/NAT behavior because they inspect and assist protocol handling for applications that embed addressing or dynamic port information inside the payload or control channel. This is part of traditional stateful firewall service behavior rather than UTM content inspection.
NEW QUESTION # 45
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?
Answer: C
Explanation:
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.
NEW QUESTION # 46
A branch using DIA with CGNAT reports that new internet sessions intermittently fail. CGNAT pool counters show increasing out-of-ports errors, while out-of-address errors remain zero. What is the most likely problem?
Answer: C
Explanation:
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.
