Your organization has hundreds of projects under a single Google Cloud organization. You need to export VPC Flow Logs from every current and future project to a single BigQuery dataset for centralized security analysis, with minimal ongoing maintenance. What should you do?
Aggregated sinks created at the org level with include-children capture logs from all descendant projects automatically, including future ones, routing to a single BigQuery dataset with the least maintenance overhead.
You created an alerting policy in Cloud Monitoring with an email notification channel. The condition triggers correctly and the incident appears in the incident list, but the on-call engineer never receives an email. What is the most likely cause?
New email notification channels in Cloud Monitoring must be verified through a confirmation email sent to the recipient; unverified channels are attached to a policy but Cloud Monitoring will not deliver notifications through them until verification completes.
You have a GKE Deployment with 10 replicas serving production traffic. Node autoscaling is disabled and the cluster only has enough spare CPU for one additional pod. You need to roll out a new version with zero downtime and without exceeding available capacity. Which rolling update configuration should you set?
maxSurge=1 creates exactly one extra pod, matching the available spare capacity, while maxUnavailable=0 guarantees all 10 original replicas keep serving traffic until each new pod is ready, achieving zero downtime within the capacity limit.
You resized a Persistent Disk attached to a running Compute Engine VM from 100GB to 500GB using gcloud compute disks resize. The Console now shows 500GB for the disk, but running df -h inside the VM still shows only 100GB available. What should you do next?
Resizing a Persistent Disk in GCP only expands the underlying block device; the guest OS file system must be manually grown with a tool such as resize2fs or growpart/xfs_growfs for the additional space to become usable.
A finance team wants Google Cloud to automatically stop project spending, not just alert on it, once a monthly budget is exceeded, using only native GCP tools. What should they configure?
Cloud Billing budgets only send alert notifications; they never automatically stop spending. To enforce an automatic cutoff, the budget's Pub/Sub notification must be wired to a Cloud Function that programmatically disables billing or shuts down resources when the threshold is crossed.
A Cloud SQL for PostgreSQL primary instance is experiencing high CPU utilization due to heavy reporting queries. You want to offload these reads without impacting write performance, and you also want a way to continue serving the database if the primary's entire region becomes unavailable. What should you do?
A cross-region read replica offloads reporting reads while also holding a copy of the data in a separate region; if the primary region fails, the replica can be manually promoted to a standalone read/write instance, providing regional disaster recovery that a same-region replica cannot.
