A developer wants to deploy a containerized web application on GCP without managing any infrastructure, scaling automatically to zero when idle. Which service fits best?
Answer: Cloud Run
Cloud Run is a fully managed serverless platform that runs containers and scales to zero when there is no traffic, eliminating idle costs.
When configuring VPC firewall rules in GCP, what is the implied default rule if no matching rule is found for ingress traffic?
Answer: Deny all ingress traffic
GCP VPCs have an implied deny-all ingress rule at the lowest priority (65535), blocking all inbound traffic unless a higher-priority allow rule exists.
Which GCP monitoring feature allows a Cloud Engineer to define a threshold on a metric and send notifications when that threshold is breached?
Answer: Alerting policy in Cloud Monitoring
An alerting policy in Cloud Monitoring specifies conditions based on metric thresholds and triggers notifications via channels like email, PagerDuty, or Pub/Sub.
