VMware 3V0-22.25 Practice Test Questions Answers

The failure is caused by removal of the Linux socket statistics utility, ss , and visibility is restored by reinstalling or restoring that utility. VCF Operations Service Discovery relies on in-guest commands to identify running services and network relationships. For UNIX/Linux operating systems, the documented Service Discovery command and utility requirements are ps , ss , and top . If a hardened Linux image removes ss under least-functionality controls, VMware Tools and the Service Discovery plug-in can still be present, but the collector cannot perform the required service enumeration. This explains why legacy Linux systems still work while newly hardened systems do not. The correction is to restore the ss utility and ensure the discovery user can execute it. The documentation also shows that for non-root Linux users, sudoers may need NOPASSWD entries that include the ss path so collection scripts do not block on password prompts . tcpdump is not listed as a Service Discovery prerequisite, and netstat is a Windows Service Discovery utility in this context, not the required Linux dependency.

The administrator must configure a Webhook Notification plug-in. Action-based notifications in VCF Operations are tied to Workload Placement actions, where the notification is sent when a workload-placement action succeeds, fails, or times out. Broadcom’s documentation for creating notification rules for notification type Action identifies this workflow as Workload Placement action-based notification. ( TechDocs ) For outbound delivery, the required plug-in type is the Webhook Notification plug-in, which is the supported outbound mechanism for sending action notification payloads to an external endpoint. Broadcom’s outbound plug-in documentation describes adding a Webhook Notification plug-in instance so alert or event data can be sent outside the operations platform. ( TechDocs ) A Log File plug-in is not used for action-based notification delivery. “SMTP Trap” is not the correct VCF Operations outbound plug-in type; email uses Standard Email, and trap delivery would be SNMP-oriented. Standard Email is valid for alert-style notification workflows, but WLP action-based notification requires Webhook.

The next required step is to download and run the helper script from the cloud proxy, then restart Telegraf . Installing Telegraf and defining OS or application input plug-ins is only part of the configuration. To send data to VCF Operations, Telegraf must also be configured with the correct output plug-in that targets the VCF Operations cloud proxy. The documentation states that after installing open source Telegraf, the administrator must run the helper script to configure Telegraf to send data to the cloud proxy. Running the helper script creates the cloudproxy-http.conf file and adds the output plug-in properties required for sending data; it also updates input plug-ins for OS metrics . The same workflow then requires the Telegraf service to be started or restarted so the new configuration is loaded . Direct communication to the VCF Operations load balancer is not the collection path; Telegraf sends to the cloud proxy or collector group. Operator rights do not control the Telegraf service runtime, and rebooting cloud proxies is unnecessary.

The correct setting is ssl_accept_any_trusted=yes in the agent configuration. VCF Operations for Logs agent SSL communication is controlled from the agent configuration file under the [server] section. A secure agent configuration uses proto=cfapi, ssl=yes, and the secure ingestion port, and then defines how the agent validates the server certificate. Broadcom documentation examples for secure Operations for Logs agent communication show the agent configuration using ssl_accept_any_trusted=yes, with ssl=yes and the certificate trust settings, to allow the agent to establish encrypted communication while accepting the trusted certificate presented by the server . Broadcom’s Operations for Logs SSL parameter documentation also states that ssl_accept_any accepts any certificate when set to yes or 1, but that is broader and less controlled than accepting the trusted self-signed certificate path . Port 9000 is not the SSL ingestion setting, and proto=syslog is not the Log Insight agent CFAPI configuration. Copying the certificate alone is not the requested agent.ini modification.

The correct troubleshooting sources are the Request Log , the Management Pack Builder Adapter log , and the Integration Designer Controller log . Management Pack Builder troubleshooting is centered on validating the API requests, collection execution, adapter behavior, and server-side design processing. The VCF 9.0 documentation states that every test request or test collection in Management Pack Builder exposes request tabs showing the body, headers, and logs; these are used to diagnose response-code errors and request/response issues . For collection problems after installation, the administrator should review Management Pack Builder Adapter logs , located under $VCOPS_BASE/user/log/adapters/MPBAdapter on the selected node or cloud proxy, because these logs show adapter-side warnings and errors during collection . If the issue appears to be with Management Pack Builder itself, the official guidance identifies /usr/lib/vmware-vcops/user/log/integration-designer-controller.log as the server-side log to review . The Design Screen is used to build and verify definitions, but it is not one of the listed troubleshooting data sources. Observability Workbench is for infrastructure troubleshooting, not Management Pack Builder design diagnostics. Reference topic: Objective 4.8 – Management Pack Builder / Troubleshooting a Design .
