- A) A button to send manual notifications
- B) A condition that determines when to send a notification
- C) A webhook endpoint
- D) A notification template
Show Answer
Answer: B) A condition that determines when to send a notification
Explanation: Triggers define the conditions (like sync status changes, health changes, or sync failures) that determine when notifications should be sent. They reference templates that format the notification content.
- How do you define a subscription directly in a specific Application’s metadata?
- A) Change the Application replica count
- B) Add annotations to the Application with notification subscriptions
- C) Create a NotificationSubscription CRD
- D) Configure it in the ArgoCD UI
Show Answer
Answer: B) Add annotations to the Application with notification subscriptions
Explanation: Applications subscribe to notifications via annotations like notifications.argoproj.io/subscribe.on-sync-succeeded.slack: my-channel. This specifies the trigger, service, and recipient. Central ConfigMap subscriptions and AppProject annotations are other supported methods. Separate multiple recipients with semicolons.
- Which notification services does ArgoCD support out of the box?
- A) Only Slack
- B) Only email
- C) Multiple including Slack, Teams, email, webhooks, and more
- D) None, all require custom plugins
Show Answer
Answer: C) Multiple including Slack, Teams, email, webhooks, and more
Explanation: Argo CD supports formats for Slack, Teams Workflows, GitHub, email, generic webhooks, SQS, and other services. Credentials, triggers, templates, and subscriptions must be configured before delivery. A template containing several service formats does not automatically broadcast to all of them. Existing Opsgenie integrations need a migration plan for its announced shutdown.
