A company runs a large-scale data processing workload on Dataflow. The pipeline processes streaming data from Pub/Sub and writes results to BigQuery. The current monthly Dataflow cost is $50,000, and the company wants to reduce it. They have already optimized the pipeline code and reduced data shuffling. They notice that the Dataflow workers are running at 100% CPU for most of the time, but the job's autoscaling is set to 'throughput-based' and currently uses 20 workers. The job's latency SLAs are tight. They consider switching to 'flexible resource scheduling' (FlexRS) to reduce costs. What should they evaluate before enabling FlexRS?

An e-commerce company uses Cloud SQL for MySQL to support their online store. The database has a 500GB dataset. They notice that monthly costs have increased significantly. On reviewing the billing export to BigQuery, they see that the highest cost is from 'Cloud SQL - Storage' and 'Cloud SQL - Backups'. They currently have automated backups enabled with a retention of 7 days. They also take manual backups before every deployment, which are stored for 30 days. They want to reduce backup storage costs without compromising disaster recovery. What should they do?

A company is using Google Cloud and wants to monitor and control costs. Which TWO actions should they take? (Choose two.)

A company runs a production workload on Google Kubernetes Engine (GKE) with cluster autoscaling enabled. The cluster has three node pools: one for general-purpose workloads (n1-standard-4), one for memory-intensive workloads (n2-highmem-8), and one for GPU-accelerated jobs (with 1 NVIDIA Tesla T4 per node). The workloads are a mix of stateless microservices and stateful databases. Over the past month, the monthly GKE cost has increased by 40% despite no significant change in application traffic or resource requests. The team has verified that vertical pod autoscaling and node auto-provisioning are enabled. They have also checked that there are no orphaned resources. They suspect that overspending is due to inefficient resource utilization or node selection. What should the team do to identify and reduce the unnecessary cost?

You are a DevOps engineer at a large e-commerce company that runs its production workloads on Google Kubernetes Engine (GKE) in the us-central1 region. The cluster has 500 nodes, each with 8 vCPUs and 32 GB of memory, and uses preemptible VMs for cost savings. Over the past month, the monthly GKE cost has increased by 30% unexpectedly. Upon reviewing the billing reports, you notice a significant spike in Compute Engine costs, specifically for 'Sustained Use Discount' line items, but the total cost is higher than expected. You also observe that the cluster's node utilization is inconsistent, with some nodes running at 90% CPU and memory while others are below 20%. Your team has been deploying stateless microservices and using Cluster Autoscaler with default settings. The application traffic is variable but predictable, with peaks on weekends. You need to reduce the GKE costs without impacting performance. What should you do?

The job is designed to handle interruptions gracefully by saving checkpoint files to Cloud Storage every few minutes. The startup wants to minimize compute costs. The current setup uses a managed instance group with 10 n1-standard-4 VMs running for the entire 6-hour window. They are considering using preemptible VMs. However, they are concerned about cost stability and potential preemption. What should they do?

A mid-size company has multiple Google Cloud projects for different departments. The finance team wants to set up budget alerts to track spending across all projects. They have enabled billing export to BigQuery. The budget should trigger alerts when total cumulative spending exceeds 80% and 100% of the monthly budget of $10,000. The budget must be applied across all projects in the organization. They created a budget at the billing account level with amount $10,000, set alert thresholds at 80% and 100%, and added email recipients. However, after two weeks, spending in one project alone has exceeded $8,000 but no alert was triggered. What is the most likely cause?
