How would you deploy a model on Vertex AI?medium

Type
scenario
Topic
vertex
Frequency
common
Answer

Register the model, deploy to an endpoint, configure scaling, monitor predictions, and control rollout.

Explanation

Include Artifact Registry, model registry, online prediction endpoints, traffic splitting, Cloud Monitoring, model evaluation, and IAM boundaries.

Follow-upHow would you compare online and batch prediction?

How do you optimize BigQuery cost and performance?medium

Type

Topic
bigquery
Frequency
common
Answer

Partition, cluster, reduce scanned columns, use materialized views, and monitor query plans.

Explanation

Interviewers want you to understand columnar storage, bytes scanned, partition pruning, clustering selectivity, slots, and avoiding SELECT * on large tables.

Follow-upWhen would you use reservations?

How would you build a streaming pipeline with Pub/Sub and Dataflow?hard

Type
scenario
Topic
pubsub-dataflow
Frequency
common
Answer

Publish events to Pub/Sub, process them with Dataflow, handle windows, write to storage, and monitor lag.

Explanation

A good answer covers event time vs processing time, retries, dead-letter topics, idempotent writes, watermarks, autoscaling, and schema evolution.

Follow-upHow would you handle duplicates?

When would you use GKE vs Cloud Run?medium

Frequency
common
Answer

Use Cloud Run for simple serverless containers and GKE when you need Kubernetes control or complex orchestration.

Explanation

Compare operational overhead, networking, autoscaling, workloads, GPU needs, service mesh, and platform team maturity.

Follow-upHow would you deploy a GPU inference service?

Which Google Cloud certifications support interview preparation?easy

Topic
cert-path
Frequency
common
Answer

Professional Machine Learning Engineer and Professional Data Engineer are most relevant for AI/data interviews.

Explanation

Use certs to organize study around BigQuery, Vertex AI, pipelines, IAM, monitoring, and cost. Pair them with hands-on deployment projects.
